Description

[Technical field]

[0001] The present invention relates to a processing machine, a processing machine stand, and a processing auxiliary tool. [Background technology]

[0002] Conventionally, known processing machines (including handheld power tools; the same applies below) that use rotating blades (bits) to cut various materials (metal, plastic, wood, and other hard and soft materials) include drill presses (including milling machines; the same applies below) as disclosed in Patent Document 1 and routers (including trimmers; the same applies below) as disclosed in Patent Document 2. [Prior art documents] [Patent documents]

[0003] [Patent Document 1] Japanese Utility Model Application Publication No. 55-129714 [Patent Document 2] Patent No. 5575713 Summary of the Invention [Problem to be solved by the invention]

[0004] In recent years, with an emphasis on high precision and mass production, processing machines equipped with NC (Numerical Control) functions that are numerically controlled by a computer (hereafter referred to as NC processing machines) have become mainstream. In other words, such NC functions are effective for mass-producing identical items with high precision. On the other hand, it is also true that due to the diversification of user needs, it is necessary to respond to the production of small quantities of a wide variety of items. Also, with the spread of DIY (Do-it-yourself), when individuals use processing machines, they actually want to easily produce only a few identical items.

[0005] However, when machining such a small quantity of many different items or a few identical items, using an NC machine inevitably increases costs and is not realistic. Also, using a drill press as disclosed in Patent Document 1 or a router as disclosed in Patent Document 2 has the problem that sufficient machining precision cannot be obtained.

[0006] The present invention has been made to solve the above-mentioned problems, and aims to provide a processing machine, a processing machine stand, and a processing auxiliary tool that can ensure high precision manually even without NC functionality. [Means for solving the problem]

[0007] In order to achieve the above object, a first aspect of the present invention is a processing machine comprising: a holding unit capable of holding a cylindrical processing tool having one end as a spindle and a blade portion with the other end of the processing tool facing downward, a first driving unit capable of rotating the processing tool held in the holding unit about the spindle, a table on which a workpiece can be mounted facing upward so as to face the one end of the processing tool, and a cylindrical or cylindrical protrusion attached to the upper surface of the table, having an axis coinciding with the spindle and having a diameter in a direction perpendicular to the spindle that is the same as the diameter of the blade portion of the processing tool in the perpendicular direction, the protrusion being used for positioning the processing tool relative to the workpiece to be moved to the same shape as a mold portion attached to the underside of the workpiece during processing of the workpiece. By using such a processing machine, the processing tool having the same spindle as the protrusion can also move along the shape of the mold portion by moving the protrusion along the shape of the mold portion during processing of the workpiece. Therefore, it becomes possible to move the processing tool to match the shape of the mold portion, and as a result, it becomes possible to perform operations with high precision such as producing a workpiece of the same shape as the mold portion from the processed material, cutting the end of the processed material to match the shape of the mold portion, or drawing a shape (pattern) on the surface of the processed material that is the same as the shape of the mold portion.

[0008] Furthermore, in the processing machine of the first embodiment, if a second drive unit capable of adjusting the vertical positional relationship between one end of the processing tool and the table is further provided, operations such as placing the workpiece on the table and removing the workpiece or workpiece from the table can be easily performed. The second drive unit may be one that manually controls the feed amount in the axial direction (vertical direction) of the processing tool or table using a handle, or one that automatically controls the feed speed in the axial direction of the processing tool or table by button operation or remote operation (for example, smartphone app operation), etc.

[0009] Furthermore, in the processing machine of the first embodiment, if the protrusion and table are configured so that when the processing tool is replaced, the protrusion can also be replaced accordingly, the protrusion can be changed according to the type of processing tool (e.g., a cutting bit, an edge processing bit, a groove cutting bit, a surface scraping bit, etc.) and its size, making it possible to perform high-precision cutting processing for various processing tools.

[0010] The second aspect of the present invention is a processing auxiliary tool used in the processing machine according to the first aspect, characterized in that it comprises a plate-shaped main body on whose upper surface a workpiece is fixed, and a mold part attached to the lower surface of the main body, and the mold part is used as a template for moving a processing tool along the shape of the mold part by moving a protruding part along the shape of the mold part when processing the workpiece. By using such a processing auxiliary tool, when processing the workpiece, a processing tool having the same main shaft as the protruding part also moves along the shape of the mold part, so that it is possible to move the processing tool to the same shape as the mold part. As a result, it is possible to perform operations such as manufacturing a workpiece having the same shape as the mold part from the workpiece, cutting the end of the workpiece to the same shape as the mold part, or drawing a shape (pattern) on the surface of the workpiece to the same shape as the mold part with high precision.

[0011] The third aspect of the present invention is a processing machine comprising: a holding part capable of holding a main shaft and a cylindrical processing tool having one end as a blade part with the other end of the processing tool facing upward; a first driving part capable of rotating the processing tool held in the holding part around the main shaft; a table having a lower surface, an upper surface, and a hole part for projecting one end of the processing tool from the lower surface side to the upper surface side, on which a workpiece can be mounted; and a cylindrical or cylindrical protrusion arranged from above the table downward, having an axis coinciding with the main shaft, and having a diameter in a direction perpendicular to the main shaft equal to the diameter of the blade part of the processing tool in the perpendicular direction, the protrusion being used for positioning the processing tool relative to the workpiece to be moved to the same shape as a mold part attached to the upper surface of the workpiece when processing the workpiece. By using such a processing machine, when processing the workpiece, the protrusion is moved along the shape of the mold part, so that the processing tool having the same main shaft as the protrusion also moves along the shape of the mold part. Therefore, it becomes possible to move the processing tool to match the shape of the mold portion, and as a result, it becomes possible to perform operations with high precision such as producing a workpiece of the same shape as the mold portion from the processed material, cutting the end of the processed material to match the shape of the mold portion, or drawing a shape (pattern) on the surface of the processed material that is the same as the shape of the mold portion.

[0012] Furthermore, in the processing machine of the third aspect, if a second drive unit capable of adjusting the vertical positional relationship between one end of the processing tool and the table is further provided, operations such as placing the workpiece on the table and removing the workpiece or workpiece from the table can be easily performed. The second drive unit may be one that manually controls the feed amount in the axial direction (vertical direction) of the processing tool or table using a handle, or one that automatically controls the feed speed in the axial direction of the processing tool or table by button operation or remote operation (for example, smartphone app operation), etc.

[0013] Furthermore, in the third embodiment of the processing machine, if the protrusion and table are configured so that when the processing tool is replaced, the protrusion can also be replaced accordingly, the protrusion can be changed according to the type of processing tool (e.g., cut-out bit, edge processing bit, groove cutting bit, surface scraping bit, etc.) and its size, making it possible to perform high-precision cutting processing for various processing tools.

[0014] The fourth aspect of the present invention is a processing auxiliary tool used in the processing machine according to the third aspect, characterized in that it comprises a plate-shaped main body on whose underside a workpiece is fixed and a mold part attached to the upper surface of the main body, and the mold part is used as a template for moving a processing tool along the shape of the mold part by moving a protruding part along the shape of the mold part when processing the workpiece. By using such a processing auxiliary tool, a processing tool having the same main shaft as the protruding part also moves along the shape of the mold part when processing the workpiece, so that it is possible to move the processing tool to the same shape as the mold part. As a result, it is possible to perform operations such as manufacturing a workpiece having the same shape as the mold part from the workpiece, cutting the end of the workpiece to the same shape as the mold part, or drawing a shape (pattern) on the surface of the workpiece to the same shape as the mold part with high precision.

[0015] A fifth aspect of the present invention relates to a processing machine stand capable of mounting a processing machine having a holding part capable of holding a main shaft and a cylindrical processing tool having one end serving as a blade portion with the other end of the processing tool facing upward, and a first drive part capable of rotating the processing tool held in the holding part around the main shaft, the processing machine stand comprising: a table having a bottom surface, a top surface, and a hole portion allowing one end of the processing tool to protrude from the bottom surface to the top surface, the bottom surface being capable of mounting the processing machine and a workpiece being mounted on the top surface; and a cylindrical or cylindrical protrusion arranged from above to below the table, having an axis coinciding with the main shaft, and having a diameter in a direction perpendicular to the main shaft that is the same as the diameter of the blade portion of the processing tool in that perpendicular direction, the protrusion being used for alignment purposes to move the processing tool relative to the workpiece to the same shape as a mold part attached to the top surface of the workpiece when processing the workpiece. By using such a processing machine stand, when processing the workpiece with the processing machine, the protruding part is moved along the shape of the mold part, and the processing tool, which has the same main shaft as the protruding part, can also be moved along the shape of the mold part. Therefore, the processing tool moves in the same shape as the mold part, and as a result, operations such as manufacturing a workpiece having the same shape as the mold part from the workpiece, cutting the end of the workpiece to the same shape as the mold part, or drawing a shape (pattern) on the surface of the workpiece to the same shape as the mold part can be performed with high precision.

[0016] Furthermore, in the processing machine of the fifth aspect, if a second drive unit capable of adjusting the vertical positional relationship between one end of the protrusion and the table is further provided, operations such as placing the workpiece on the table and removing the workpiece or workpiece from the table can be easily performed. The second drive unit may be one that manually controls the feed amount in the axial direction (vertical direction) of the processing tool or table using a handle, or one that automatically controls the feed speed in the axial direction of the processing tool or table by button operation or remote operation (for example, smartphone app operation), etc.

[0017] Furthermore, in the processing machine of the fifth aspect, if the protrusion is configured to be replaceable when the processing tool is replaced, the protrusion can be changed according to the type of processing tool (e.g., a cutting bit, an edge processing bit, a groove cutting bit, a surface scraping bit, etc.) and its size, making it possible to perform high-precision cutting processing for various processing tools.

[0018] The sixth aspect of the present invention is a processing auxiliary tool used for the processing machine stand according to the fifth aspect, characterized in that it comprises a plate-shaped main body on whose underside a workpiece is fixed and a mold part attached to the upper surface of the main body, and the mold part is used as a template for moving a processing tool along the shape of the mold part by moving a protruding part along the shape of the mold part when processing the workpiece. By using such a processing auxiliary tool, when processing the workpiece with a processing machine, a processing tool having the same main shaft as the protruding part also moves along the shape of the mold part, so that it is possible to move the processing tool to the same shape as the mold part. As a result, it is possible to perform operations such as manufacturing a workpiece having the same shape as the mold part from the workpiece, cutting the end of the workpiece to the same shape as the mold part, or drawing a shape (pattern) on the surface of the workpiece to the same shape as the mold part with high precision. Effect of the Invention

[0019] According to each aspect of the present invention, it is possible to realize a processing machine, a stand for the processing machine, and a processing auxiliary tool that can ensure high precision manually even without NC functions. This makes it possible to process a small amount of a wide variety of products or several identical items without increasing costs. [Brief description of the drawings]

[0021] Hereinafter, an embodiment of the present invention will be described with reference to the drawings.

[0022] In the following description, the processing tool (e.g., a bit) is assumed to have a cylindrical shape as a whole, with a main shaft and one end serving as a cutting part. The upward direction, the upper side, and the upper side are respectively parallel to the main shaft of the processing tool and generally opposite to the direction of the earth's gravity. The downward direction, the lower side, and the lower side are respectively parallel to the main shaft of the processing tool and generally in the direction of the earth's gravity. Furthermore, the left-right direction is a direction perpendicular to the main shaft of the processing tool and refers to the left-right direction as seen by a user of the processing machine, the processing machine stand, and the processing auxiliary tool. Furthermore, the front-rear direction is a direction perpendicular to the main shaft of the processing tool and refers to the front-rear direction as seen by a user of the processing machine, the processing machine stand, and the processing auxiliary tool.

[0023] (First embodiment) ·Processing machine FIG. 1 shows a processing machine according to a first embodiment of the present invention. The processing machine according to the first embodiment includes a holding unit 12 capable of holding a processing tool 11, a first driving unit 13 capable of rotating the processing tool 11 held by the holding unit 12 about a main axis AX, a table 14 on which a workpiece can be mounted with its processing surface (the surface facing the processing tool 11) facing upward, and a protrusion 16 attached to the upper surface and center of the table 14. The holding unit 12, the first driving unit 13, and the table 14 are attached to a pillar-shaped member 10B called a column that supports them. The pillar-shaped member 10B is attached to a foundation 10A called a base in order to stably place the processing machine on a substrate such as the ground, a floor, or a desk.

[0024] The processing tool 11 has a blade portion SP at one end and a handle portion at the other end. The holding portion 12 can hold the handle portion at the other end of the processing tool 11 with the blade portion SP at one end of the processing tool 11 facing downward. The processing tool 11 can change its function, for example, cutting, grooving, drilling, carving, grinding, etc., depending on the shape of the blade portion SP. The holding portion 12 grasps and holds the handle portion at the other end of the processing tool 11, and transmits a rotational motion about the main axis AX to the processing tool 11. The first driving portion 13 has an electric motor and generates a rotational motion that is transmitted to the processing tool 11. As a result, the processing tool 11 held by the holding portion 12 can rotate about the main axis AX.

[0025] The second drive unit 15 has a function of adjusting the positional relationship in the main axis direction (vertical direction) between one end of the processing tool 11 and the table 14. The second drive unit 15 may be one that manually operates the vertical feed amount of the processing tool 11, for example, one that includes a handle that manually generates a rotational force and a rack and pinion that converts the rotational force into linear movement (vertical movement) of the processing tool 11 and the holding unit 12, or may be one that automatically operates the vertical feed speed of the processing tool 11 and the holding unit 12 by button operation or remote operation (for example, smartphone app operation).

[0026] Further, instead of these, the second driving unit 15 may change the vertical position of the table 14 instead of the processing tool 11 and the holding unit 12. Also, the second driving unit 15 may change both the vertical positions of the processing tool 11 and the holding unit 12 and the vertical position of the table 14.

[0027] The second drive unit 15 can be omitted, but by providing it, it has the effect of making it easier to perform operations such as placing the workpiece on the table 14 and removing the workpiece or workpiece from the table 14.

[0028] The table 14 is intended to mount the workpiece with its processing surface facing upward so that the processing surface of the workpiece faces the blade portion SP at one end of the processing tool 11, making it easier for the user to process the workpiece using this processing machine. The upper surface of the table 14 is preferably perpendicular to the main axis AX and flat. The upper surface of the table 14 may also be provided with concentric or radial grooves or patterns to assist in processing the workpiece. In this example, the table 14 has a disk shape, but the shape of the table is not limited to this and may be replaced with other shapes such as a square plate.

[0029] A protrusion 16 is provided at the center of the table 14, protruding upward from the upper surface of the table 14. The protrusion 16 has an axis coinciding with the main axis (rotation axis) AX of the processing tool 11 held by the holding part 12, and has a columnar or cylindrical shape so as to have the same external shape as the processing tool 11. Furthermore, the diameter φ1 of the protrusion 16 in a direction perpendicular to the main axis AX is the same as the diameter φ2 of the blade portion SP of the processing tool 11 in the perpendicular direction. Here, the diameter φ2 of the blade portion SP of the processing tool 11 means the diameter of the blade portion SP when the diameter is constant, and means the maximum diameter when the diameter of the blade portion SP changes.

[0030] This protrusion 16 is used for alignment purposes when processing the workpiece on the table 14, to move the processing tool 11 relative to the workpiece to match the shape of a mold portion (details of which will be described later) attached to the underside of the workpiece.

[0031] For this positioning application, it is desirable that the protrusion amount (height) h of the protrusion 16 is set to be equal to or smaller than the thickness of the mold part attached to the underside of the workpiece. This is a device to make it easier for the user to operate the processing auxiliary tool (details of which will be described later) when processing the workpiece using this processing machine, and to improve the positioning accuracy. Specifically, this is to prevent the processing auxiliary tool (workpiece) from rattling or shaking in the vertical direction when processing the workpiece. In other words, if the protrusion amount h of the protrusion 16 is larger than the thickness of the mold part attached to the underside of the workpiece, a space will be generated between the mold part and the upper surface of the table 14, and the processing auxiliary tool will not be stable when processing the workpiece, so the above-mentioned provision of the protrusion amount h is intended to prevent this.

[0032] Further, to further evolve this positioning application, it is desirable that the protrusion 16 and the table 14 are configured so that when the processing tool 11 is replaced, the protrusion 16 can also be replaced accordingly. This is because when the type of processing changes, the type of processing tool (for example, a cutting bit, an edge processing bit, a groove cutting bit, a surface scraping bit, etc.) also changes. In other words, since the diameter φ2 of the blade portion SP of the processing tool 11 changes depending on the type of processing tool 11, when various processing is performed using this processing machine, it is desirable that the protrusion 16 is configured so as to be replaceable in order to ensure high precision for these various processing.

[0033] By using such a processing machine according to the first embodiment, when processing a workpiece, the protrusion 16 is moved along the shape of the mold portion, and the processing tool 11, which has the same main axis AX as the protrusion 16, also moves along the shape of the mold portion. Therefore, it is possible to move the processing tool 11 along the shape of the mold portion, and as a result, it is possible to perform operations with high precision, such as manufacturing a workpiece having the same shape as the mold portion from the workpiece, cutting the end of the workpiece into the same shape as the mold portion, or drawing a shape (pattern) on the surface of the workpiece that is the same as the shape of the mold portion.

[0034] - First example of processing aid Fig. 2(a) shows a first example of a processing auxiliary tool used in the processing machine of Fig. 1, in which the mold part is an elliptical shape having only an outer shape. Fig. 2(b) is a cross-sectional view taken along line II-II of Fig. 2(a). Fig. 2(c) shows a state in which a workpiece is mounted on the processing auxiliary tool of Fig. 2(b).

[0035] This processing aid comprises a plate-shaped main body 20 to which a workpiece 26 is fixed on the upper surface side, and a mold part 21 attached to the lower surface of the main body 20. The workpiece 26 is not particularly limited, but is mainly resin (plastic material) or wood. The main body 20 can be made of, for example, resin such as acrylic or FRP (Fiber Reinforced Plastics), metal such as aluminum alloy or iron, glass such as soda glass, or wood such as lauan. It is desirable for the main body 20 to have sufficient strength, and from that viewpoint, the material and thickness are appropriately selected. In addition, it is desirable for the main body 20 to be made of a transparent material, for example, a transparent acrylic plate or a glass plate, in order to improve the visibility of the mold part 21 by the user when processing the workpiece 26.

[0036] The mold part 21 is used as a template for moving the processing tool 11 in FIG. 1 along the shape (outer shape) of the mold part 21 by moving the protrusion 16 in FIG. 1 along the shape of the mold part 21 when processing the workpiece 26. The mold part 21, like the main body 20, can be made of, for example, resin such as acrylic or FRP, metal such as aluminum alloy or iron, glass such as soda glass, or wood such as lauan. When the main body 20 and the mold part 21 are made of the same material, they may be integrated (integrally molded). When the main body 20 and the mold part 21 are made of different materials, it is also possible to make the main body 20 out of a transparent material and the mold part 21 out of an opaque material.

[0037] Furthermore, although not essential components of this processing aid, the processing aid may be provided with the following components for purposes such as preventing damage to the processing aid when processing the workpiece 26 and improving operability for the user.

[0038] For example, a plate-shaped buffer layer 22 may be provided on the upper surface of the main body 20. The buffer layer 22 is intended to prevent the tip of the blade portion SP of the processing tool 11 in FIG. 1 from penetrating through the main body 20 or beyond it during processing of the workpiece 26, causing damage to the processing auxiliary tool. From this perspective, it is preferable that the buffer layer 22 is made of a material softer than the processing tool 11, such as resin or wood. In addition, in order to improve the visibility of the above-mentioned mold portion 21, it is preferable that the buffer layer 22 is also made of a transparent material, such as a transparent acrylic plate. The material and thickness of the buffer layer 22 are appropriately selected from the perspective of preventing the blade portion SP of the processing tool 11 from penetrating through. In addition, when the main body 20 also has the function of the buffer layer 22, the buffer layer 22 can be omitted.

[0039] In addition, the left and right ends of the main body 20 may be provided with a fixing portion for fixing the workpiece 26 and a handle 25 for improving the user's operability. In this example, the fixing portion includes a frame portion 23 into which the workpiece 26 is fitted and a screw portion 24 for fixing the workpiece 26. However, the fixing portion is not limited to this, and various configurations can be adopted as long as the workpiece 26 can be fixed. Two handles 25 are provided, one on the left side of the main body 20 and one on the right side of the main body. The left handle 25 is a portion that the user's left hand holds, and the right handle 25 is a portion that the user's right hand holds. By providing such handles 25, the user can freely move the processing auxiliary tool in the up and down direction, the left and right direction, and the front and back direction, respectively, without any discomfort, with good operability.

[0040] 1 and the main axis AX, moves along the shape of the mold part 21 during processing of the workpiece 26, so that it is possible to move the workpiece 11 to the same shape (outer shape) as the mold part 26. As a result, it is possible to perform operations with high precision, such as manufacturing a workpiece having the same shape as the mold part 21 from the workpiece 26, cutting the end of the workpiece 26 to the same shape as the mold part 21, or drawing a shape (pattern) on the surface of the workpiece 26 that is the same shape as the mold part 21 (outer shape).

[0041] Processing method using the processing auxiliary tool in the first example Next, an example of a processing method for processing a workpiece using the above-mentioned processing machine and processing auxiliary tool will be described with reference to Figures 3 to 6. Here, as an example, a processing method for manufacturing a workpiece having the same shape as the shape of the mold part of the processing auxiliary tool from the workpiece will be described. In the following explanation, for ease of understanding, the drawings will show only the processing tool 11, table 14, and protrusion 16 on the processing machine side, and only the main body 20, mold portion 21, buffer layer 22, and processing material 26 on the processing auxiliary tool side.

[0042] First, as shown in FIG. 3, the workpiece 26 is mounted and fixed on the processing aid. After that, the user holds the handle of the processing aid and moves the processing aid onto the table 14 of the processing machine. At this time, the mold part 21 of the processing aid is in contact with the upper surface of the table 14, and a part of the outer shape of the mold part 21 (cutting start point) is in contact with the protruding part 16. In this state, the processing machine is driven to rotate the processing tool 11 (to make it in a cutting possible state). Next, the processing machine is operated to move the tip (blade part) of the processing tool 11 downward to start cutting the processing material 26. In addition, the tip of the processing tool 11 is further moved downward to penetrate the processing material 26 (cutting). Here, since the buffer layer 22 exists as the base of the processing material 26, even if the tip of the processing tool 11 penetrates the processing material 26, the processing aid is not damaged.

[0043] Next, as shown in Figures 4 and 5, the user operates the processing auxiliary tool in the left-right and front-back directions to move the protrusion 16 of the processing machine from the cutting start point to the shape (outer shape) of the mold part 21 of the processing auxiliary tool until it returns to the cutting start point again (to the cutting end point). At this time, the protrusion 16 of the processing machine moves to the shape of the mold part 21 of the processing auxiliary tool. Similarly, the processing tool 11 having the same main axis AX as the axis of the protrusion 16 also moves to the shape of the mold part 21. Therefore, as shown in Figure 4 (cutting midpoint) and Figure 5 (cutting end point), it is possible to move the processing tool 11 of the processing machine to the same shape as the mold part 21 of the processing auxiliary tool.

[0044] As a result, as shown in FIG. 6, a workpiece 26g having the same shape (outer shape) as the shape of the die portion 21 of the processing auxiliary tool can be manufactured from the workpiece 26.

[0045] Second example of processing aid Fig. 7(a) shows a second example of a processing auxiliary tool used in the processing machine of Fig. 1, the mold part of which is a frame-shaped ellipse having an outer shape and an inner shape. Fig. 7(b) is a cross-sectional view taken along line VII-VII of Fig. 7(a). Fig. 7(c) shows a state in which a workpiece is loaded onto the processing auxiliary tool of Fig. 7(b).

[0046] This processing auxiliary tool is characterized by the shape of the mold portion 21 when compared with the first example (FIGS. 2(a) to 2(c)). Other points are the same as those of the first example. Therefore, in the following explanation, the same elements as those of the first example are given the same reference numerals, and detailed explanations thereof will be omitted.

[0047] The processing auxiliary tool of the second example mainly comprises a plate-shaped main body 20 to which workpiece 26 is fixed on the upper surface, and a frame-shaped elliptical mold part 21 attached to the lower surface of the main body 20. The mold part 21 is used as a template for moving the processing tool 11 in Fig. 1 along the shape of the mold part 21 (the outer or inner shape of the frame shape) by moving the protrusion 16 in Fig. 1 along the shape of the mold part 21 when processing the workpiece 26.

[0048] As in the first example, the mold part 21 can be made of, for example, resin such as acrylic or FRP, metal such as aluminum alloy or iron, glass such as soda glass, or wood such as lauan. When the main body 20 and the mold part 21 are made of the same material, they may be integrated (integrally molded). When the main body 20 and the mold part 21 are made of different materials, it is also possible to make the main body 20 from a transparent material and the mold part 21 from an opaque material.

[0049] 1 and the shape (external or internal shape) of the mold portion 21 during machining of the workpiece 26, it is possible to move the workpiece 11 to the same shape as the mold portion 26. As a result, it is possible to perform operations with high precision, such as manufacturing a workpiece having the same shape as the mold portion 21 from the workpiece 26, cutting the end of the workpiece 26 to the same shape as the mold portion 21, or drawing a shape (pattern) on the surface of the workpiece 26 that is the same shape as the mold portion 21 (external shape).

[0050] - Processing method using processing auxiliary tools in the second example Next, an example of a processing method for processing a workpiece using the processing machine of Fig. 1 and the processing auxiliary tool of the second example described above will be described with reference to Fig. 8 to Fig. 11. Here, as an example, a processing method for manufacturing a workpiece having the same shape as the shape (inner shape) of the mold part of the processing auxiliary tool from the workpiece will be described. In the following explanation, for ease of understanding, the drawings will show only the processing tool 11, table 14, and protrusion 16 on the processing machine side, and only the main body 20, mold portion 21, buffer layer 22, and processing material 26 on the processing auxiliary tool side.

[0051] First, as shown in FIG. 8, the workpiece 26 is mounted and fixed on the processing aid. After that, the user holds the handle of the processing aid and moves the processing aid onto the table 14 of the processing machine. At this time, the mold part 21 of the processing aid is in contact with the upper surface of the table 14, and a part of the inner shape of the mold part 21 (cutting start point) is in contact with the protruding part 16. In this state, the processing machine is driven to rotate the processing tool 11 (to make it in a cutting possible state). Next, the processing machine is operated to move the tip (blade part) of the processing tool 11 downward to start cutting the processing material 26. In addition, the tip of the processing tool 11 is further moved downward to penetrate the processing material 26 (cutting). Here, since the buffer layer 22 exists as the base of the processing material 26, even if the tip of the processing tool 11 penetrates the processing material 26, the processing aid is not damaged.

[0052] Next, as shown in Figures 9 and 10, the user operates the processing auxiliary tool in the left-right and front-back directions to move the protrusion 16 of the processing machine from the cutting start point to the shape (inner shape) of the mold part 21 of the processing auxiliary tool until it returns to the cutting start point again (to the cutting end point). At this time, the protrusion 16 of the processing machine moves to the shape of the mold part 21 of the processing auxiliary tool. Similarly, the processing tool 11 having the same main axis AX as the axis of the protrusion 16 also moves to the shape of the mold part 21. Therefore, as shown in Figures 9 (cutting midpoint) and 10 (cutting end point), it is possible to move the processing tool 11 of the processing machine to the same shape as the mold part 21 of the processing auxiliary tool.

[0053] As a result, as shown in FIG. 11, a workpiece 26g having the same shape as the shape (inner shape) of the die portion 21 of the processing auxiliary tool can be manufactured from the workpiece 26.

[0054] -Modification of processing aids Next, with reference to Figures 12 to 17, it will be explained how various cutting operations can be performed on the workpiece by changing the mold part 21 of the processing auxiliary tool in Figure 2. In these explanations, for the sake of simplicity, only the main body 20 and the mold part 21 of the components in Figure 2 will be illustrated and explained.

[0055] First, in the case of manufacturing a workpiece having the same shape as the shape of the mold part from the processed material, for example, as shown in Fig. 12(a), by changing the mold part 21 of the processing auxiliary tool to a cross shape, a cross-shaped workpiece having the same shape as the mold part 21 can be obtained from the processed material. Similarly, as shown in Figs. 12(b) and (c), by changing the mold part 21 of the processing auxiliary tool to a crescent shape and a heart shape, respectively, a crescent-shaped workpiece having the same shape as the mold part 21 can be obtained from the processed material.

[0056] In addition, by using a processing auxiliary tool in which the mold portion 21 of the processing auxiliary tool has been modified to a square shape (large) as shown in Figure 13(a) and a processing auxiliary tool in which the mold portion 21 of the processing auxiliary tool has been modified to a square shape (small) as shown in Figure 13(b), it is possible to manufacture a frame-shaped workpiece 26g having a width equivalent to the size difference between the two as shown in Figure 13(c).

[0057] Next, in the case where the end of the workpiece is cut to have the same shape as the mold portion, for example, by changing the mold portion 21 of the processing aid to a rectangular shape as shown in Figure 14(a), a workpiece 26edg whose end shape is the same rectangular shape as the mold portion 21 can be produced from the workpiece, as shown in Figure 14(b).

[0058] Next, in the case of drawing a shape (pattern) on the surface of the workpiece that is the same as the shape of the mold parts, for example, as shown in Figures 15(a)-(c) and 16(a)-(b), by using five circular mold parts 21a, 21b, 21c, 21d, and 21e of the same size but shifted in relative positions, a five-ring shape (pattern) 26des can be drawn on the surface of the workpiece as shown in Figure 17. The relative positions of the mold parts 21a, 21b, 21c, 21d, and 21e based on the main body 20 are illustrated as shown in Figure 16(c).

[0059] As described above, according to the first embodiment, by moving the protruding portion along the shape of the mold portion when machining the workpiece, the machining tool having the same main shaft as the protruding portion can also be moved along the shape of the mold portion. Therefore, it is possible to realize a machining machine and machining auxiliary tool that can ensure high precision manually even without NC function. This makes it possible to handle machining of small quantities of a wide variety of products or several identical items without increasing costs.

[0060] Second embodiment ·Processing machine FIG. 18 shows a processing machine according to a second embodiment of the present invention. The processing machine according to the second embodiment includes a holding unit 12 capable of holding a processing tool 11, a first driving unit 13 capable of rotating the processing tool 11 held by the holding unit 12 around the spindle AX, a table 14 having a lower surface, an upper surface, and a hole OP that protrudes one end of the processing tool 11 from the lower surface side to the upper surface side, on which a workpiece can be mounted with the processing surface facing downward, and a protrusion 16 arranged from above the hole OP of the table 14 downward. The holding unit 12, the first driving unit 13, the table 14, and the protrusion 16 are attached to a columnar member 10B that supports them, for example, and is called a column. The columnar member 10B is attached to a base 10A called a base in order to stably place the processing machine on a substrate such as the ground, a floor, or a desk.

[0061] The processing tool 11 has a blade portion SP at one end and a handle portion at the other end. The holding part 12 can hold the handle portion at the other end of the processing tool 11 with the blade portion SP at one end of the processing tool 11 facing upward. The processing tool 11 can change its function, for example, cutting, grooving, drilling, carving, grinding, etc., depending on the shape of the blade portion SP. The holding part 12 grasps and holds the handle portion at the other end of the processing tool 11, and transmits a rotational motion about the main axis AX to the processing tool 11. The first driving part 13 has an electric motor and generates a rotational motion that is transmitted to the processing tool 11. As a result, the processing tool 11 held by the holding part 12 can rotate about the main axis AX.

[0062] The second drive unit 15 has a function of adjusting the positional relationship in the main axis direction (vertical direction) between one end of the processing tool 11 and the table 14. The second drive unit 15 may be one that manually operates the vertical feed amount of the processing tool 11, for example, one that includes a handle that manually generates a rotational force and a rack and pinion that converts the rotational force into linear movement (vertical movement) of the processing tool 11 and the holding unit 12, or may be one that automatically operates the vertical feed speed of the processing tool 11 and the holding unit 12 by button operation or remote operation (for example, smartphone app operation).

[0063] Further, instead of these, the second driving unit 15 may change the vertical position of the table 14 instead of the processing tool 11 and the holding unit 12. Also, the second driving unit 15 may change both the vertical positions of the processing tool 11 and the holding unit 12 and the vertical position of the table 14.

[0064] The table 14 is intended to mount the workpiece with its processing surface facing downward so that the processing surface of the workpiece faces the blade portion SP at one end of the processing tool 11, making it easier for the user to process the workpiece using this processing machine. The upper surface of the table 14 is preferably perpendicular to the main axis AX and flat. The upper surface of the table 14 may also be provided with concentric or radial grooves or patterns to assist in processing the workpiece. In this example, the table 14 has a disk shape, but the shape of the table is not limited to this and may be replaced with other shapes such as a square plate.

[0065] A protrusion 16 is provided above a hole OP in the center of the table 14, extending downward from the top of the table 14. The protrusion 16 has an axis coinciding with the main axis (rotation axis) AX of the processing tool 11 held by the holding part 12, and has a columnar or cylindrical shape so as to have the same external shape as the processing tool 11. Furthermore, the diameter φ1 of the protrusion 16 in a direction perpendicular to the main axis AX is the same as the diameter φ2 of the blade portion SP of the processing tool 11 in the perpendicular direction. Here, the diameter φ2 of the blade portion SP of the processing tool 11 means the diameter of the blade portion SP when the diameter is constant, and means the maximum diameter when the diameter of the blade portion SP changes.

[0066] This protrusion 16 is used for alignment purposes when processing the workpiece on the table 14, to move the processing tool 11 relative to the workpiece to match the shape of a mold portion (details of which will be described later) attached to the underside of the workpiece.

[0067] Regarding this alignment application, in the second embodiment, there is no protrusion 16 on the table 14. That is, the upper surface of the table 14 is flat, and only the processing surface of the workpiece comes into contact with this flat upper surface (details will be described later). Therefore, the user can more easily operate the processing auxiliary tool (details will be described later) compared to the case where the processing machine and processing auxiliary tool of the first embodiment are used, and as a result, the alignment accuracy can be further improved.

[0068] In addition, it is preferable that the protruding portion 16 is configured so as to be replaceable when the processing tool 11 is replaced. This is because when the type of processing changes, the type of processing tool (for example, a cutting bit, an edge processing bit, a groove cutting bit, a surface scraping bit, etc.) also changes. In other words, since the diameter φ2 of the blade portion SP of the processing tool 11 changes according to the type of processing tool 11, when various processing is performed using this processing machine, it is preferable that the protruding portion 16 is configured so as to be replaceable in order to ensure high precision for these various processing.

[0069] By using such a processing machine according to the second embodiment, when processing a workpiece, the protrusion 16 is moved along the shape of the mold portion, and the processing tool 11, which has the same main axis AX as the protrusion 16, also moves along the shape of the mold portion. Therefore, it is possible to move the processing tool 11 along the shape of the mold portion, and as a result, it is possible to perform operations with high precision, such as manufacturing a workpiece having the same shape as the mold portion from the workpiece, cutting the end of the workpiece into the same shape as the mold portion, or drawing a shape (pattern) on the surface of the workpiece that is the same as the shape of the mold portion.

[0070] Third embodiment ·Processing machine In recent years, with the concept of being easier and simpler, processing machines (including handy types) such as routers (including mini-routers) that are compact and lightweight by removing the base 10A, column 10B, table 14, second drive unit 15, etc. from the processing machines shown in Figures 1 and 18 have been available on the market. While such processing machines have the advantage of being able to be used easily anywhere, they are somewhat inconvenient to use, as skilled techniques are required to obtain sufficient processing accuracy.

[0071] Therefore, the present inventors have studied and verified whether the present invention can be easily applied to such commercially available processing machines, and whether a certain level of processing accuracy can be obtained regardless of the type of processing machine used. As a result, the inventors have come to the conclusion that the same effects as the processing machines according to the first and second embodiments can be obtained by devising a processing machine stand (corresponding to table 14 in Figs. 1 and 18) used in such processing machines independently of the processing machines. An example of a processing machine stand that led to this conclusion will be described below.

[0072] FIG. 19 shows a processing machine stand according to a third embodiment of the present invention. The processing machine stand according to the third embodiment includes a table 14 having a lower surface, an upper surface, and a hole portion OP that projects one end of a processing tool 11 of a processing machine R / T from the lower surface side to the upper surface side, on which a workpiece can be mounted with the processing surface facing downward, and a protrusion portion 16 that is arranged downward from above the hole portion OP of the table 14. The table 16 is configured so that the processing machine R / T can be attached to its lower surface by an attachment member 17 such as a screw or a hook. That is, the processing machine R / T is suspended from the table 14 on the lower surface of the table 14. The attachment member 17 is also adjustable in length (the vertical distance between the processing machine R / T and the table 14) in order to adjust the vertical position of the processing machine R / T.

[0073] The processing machine R / T is a commercially available processing machine and is not limited to a particular type, but for example, its main components include a main spindle AX, a holding portion 12 capable of holding one end of a cylindrical processing tool 11 having one end as a cutting portion SP, with the other end of the processing tool 11 facing upward, and a first drive unit 13 capable of rotating the processing tool 11 held by the holding portion 12 around the main spindle AX.

[0074] The table 14 and the protruding portion 16 are attached to a pillar-shaped member 10B called a column that supports them. The pillar-shaped member 10B is attached to a foundation 10A called a base so that the processing machine stand can be stably placed on an underlying surface such as the ground, a floor, or a desk.

[0075] The second drive unit 15 has a function of adjusting the positional relationship in the main axis direction (vertical direction) between one end of the protrusion 16 and the table 14. The second drive unit 15 may be one that manually operates the vertical feed amount of the protrusion 16, for example, one that includes a handle that manually generates a rotational force and a rack and pinion that converts the rotational force into linear movement (vertical movement) of the processing tool 11 and the holding unit 12, or may be one that automatically operates the vertical feed speed of the protrusion 16 by button operation or remote operation (for example, smartphone app operation).

[0076] Further, instead of these, the second drive unit 15 may change the vertical position of the table 14 and the processing machine R / T instead of the protrusion 16. Also, the second drive unit 15 may change both the vertical position of the protrusion 16 and the vertical position of the table 14 and the processing machine R / T.

[0077] The table 14 is intended to mount the workpiece with its processing surface facing downward so that the processing surface of the workpiece faces the blade portion SP at one end of the processing tool 11, making it easier for the user to process the workpiece using this processing machine. The upper surface of the table 14 is preferably perpendicular to the main axis AX and flat. The upper surface of the table 14 may also be provided with concentric or radial grooves or patterns to assist in processing the workpiece. In this example, the table 14 has a disk shape, but the shape of the table is not limited to this and may be replaced with other shapes such as a square plate.

[0078] A protrusion 16 is provided above a hole OP in the center of the table 14, extending downward from the top of the table 14. The protrusion 16 has an axis coinciding with the main axis (rotation axis) AX of the processing tool 11 held by the holding part 12, and has a columnar or cylindrical shape so as to have the same external shape as the processing tool 11. Furthermore, the diameter φ1 of the protrusion 16 in a direction perpendicular to the main axis AX is the same as the diameter φ2 of the blade portion SP of the processing tool 11 in the perpendicular direction. Here, the diameter φ2 of the blade portion SP of the processing tool 11 means the diameter of the blade portion SP when the diameter is constant, and means the maximum diameter when the diameter of the blade portion SP changes.

[0079] This protrusion 16 is used for alignment purposes when processing the workpiece on the table 14, to move the processing tool 11 relative to the workpiece to match the shape of a mold portion (details of which will be described later) attached to the underside of the workpiece.

[0080] Regarding this alignment application, in the third embodiment, like the second embodiment, there is no protrusion 16 on the table 14. That is, the upper surface of the table 14 is flat, and only the processing surface of the workpiece comes into contact with this flat upper surface (details will be described later). Therefore, it is easier for the user to operate the processing auxiliary tool (details will be described later) compared to the case where the processing machine and processing auxiliary tool of the first embodiment are used, and as a result, the alignment accuracy can be further improved.

[0081] In addition, it is preferable that the protruding portion 16 is configured so as to be replaceable when the processing tool 11 is replaced. This is because when the type of processing changes, the type of processing tool (for example, a cutting bit, an edge processing bit, a groove cutting bit, a surface scraping bit, etc.) also changes. In other words, since the diameter φ2 of the blade portion SP of the processing tool 11 changes according to the type of processing tool 11, when various processing is performed using this processing machine, it is preferable that the protruding portion 16 is configured so as to be replaceable in order to ensure high precision for these various processing.

[0082] If such a processing machine stand according to the third embodiment is used, when the processing machine R / T is attached to the processing machine stand, the configuration will be the same as that of the processing machine of the second embodiment. That is, when processing a workpiece, by moving the protruding portion 16 along the shape of the mold portion, the processing tool 11, which has the same main axis AX as the protruding portion 16, also moves along the shape of the mold portion. Therefore, it is possible to move the processing tool 11 in the same shape as the mold portion, and as a result, it is possible to perform operations with high precision, such as manufacturing a workpiece having the same shape as the mold portion from the workpiece, cutting the end of the workpiece to the same shape as the mold portion, or drawing a shape (pattern) on the surface of the workpiece to the same shape as the mold portion.

[0083] (Examples of processing aids) Next, an example of a processing auxiliary tool used in the processing machine according to the second embodiment and the processing machine stand according to the third embodiment will be described. In the second and third embodiments, as described in the first embodiment, the processing auxiliary tool can be, for example, a mold portion 21 having only an outer shape (FIG. 2) or a frame shape having an outer shape and an inner shape (FIG. 7). Hereinafter, an example of a processing auxiliary tool used in the second and third embodiments in the case where a tool having only an outer shape is used as the mold portion 21 will be described.

[0084] Fig. 20(a) shows an example of a processing auxiliary tool used in the processing machine of Fig. 18 or the processing machine stand of Fig. 19, in which the mold part is an elliptical shape having only an outer shape. Fig. 20(b) is a cross-sectional view taken along line XX-XX of Fig. 20(a). Fig. 20(c) shows a state in which a workpiece is loaded on the processing auxiliary tool of Fig. 20(b).

[0085] This processing auxiliary tool comprises a plate-shaped main body 20 to which a workpiece 26 is fixed on the underside, and a mold part 21 attached to the upper surface of the main body 20. The workpiece 26 is not particularly limited, but is mainly resin (plastic material) or wood. The main body 20 can be made of, for example, resin such as acrylic or FRP, metal such as aluminum alloy or iron, glass such as soda glass, or wood such as lauan. It is desirable for the main body 20 to have sufficient strength, and from that viewpoint, the material and thickness are appropriately selected.

[0086] The mold part 21 is used as a template for moving the processing tool 11 of FIG. 18 or 19 along the shape (outer shape) of the mold part 21 by moving the protruding part 16 of FIG. 18 or 19 along the shape of the mold part 21 when processing the workpiece 26. The mold part 21 can be made of, for example, resin such as acrylic or FRP, metal such as aluminum alloy or iron, glass such as soda glass, or wood such as lauan, just like the main body 20. When the main body 20 and the mold part 21 are made of the same material, they may be integrated (integrally molded). In addition, the main body 20 and the mold part 21 may be made of different materials. In this example, the mold part 21 is disposed at the top of the processing auxiliary tool, so that the user can easily view the mold part 21, unlike the first embodiment, even if the main body 20 is not made of a transparent material.

[0087] Furthermore, although not essential components of this processing aid, similarly to the first embodiment, the processing aid may be provided with the following components for purposes such as preventing damage to the processing aid when processing the workpiece 26 and improving operability for the user.

[0088] For example, a plate-shaped buffer layer 22 may be provided on the lower surface of the main body 20. The buffer layer 22 is intended to prevent the tip of the blade portion SP of the processing tool 11 shown in FIG. 18 or FIG. 19 from penetrating through the main body 20 or beyond it during processing of the workpiece 26, causing damage to the processing auxiliary tool. From this viewpoint, it is preferable that the buffer layer 22 is made of a material softer than the processing tool 11, such as resin or wood. The material and thickness of the buffer layer 22 are appropriately selected from the viewpoint of preventing the blade portion SP of the processing tool 11 from penetrating through. In addition, when the main body 20 also has the function of the buffer layer 22, the buffer layer 22 can be omitted.

[0089] In addition, the left and right ends of the main body 20 may be provided with a fixing portion for fixing the workpiece 26 and a handle 25 for improving the user's operability. In this example, the fixing portion includes a frame portion 23 into which the workpiece 26 is fitted and a screw portion 24 for fixing the workpiece 26. However, the fixing portion is not limited to this, and various configurations can be adopted as long as the workpiece 26 can be fixed. Two handles 25 are provided, one on the left side of the main body 20 and one on the right side of the main body. The left handle 25 is a portion that the user's left hand holds, and the right handle 25 is a portion that the user's right hand holds. By providing such handles 25, the user can freely move the processing auxiliary tool in the up and down direction, the left and right direction, and the front and back direction, respectively, without any discomfort, with good operability.

[0090] By using such a processing auxiliary tool, the processing tool 11, which has the same main axis AX as the protrusion 16, also moves along the shape of the mold part 21 when processing the workpiece 26, so it becomes possible to move the processing tool 11 to the same shape (outer shape) of the mold part 26. As a result, it becomes possible to perform operations with high precision, such as manufacturing a workpiece having the same shape as the mold part 21 from the workpiece 26, cutting the end of the workpiece 26 to the same shape as the mold part 21, or drawing a shape (pattern) on the surface of the workpiece 26 that is the same shape as the mold part 21 (outer shape).

[0091] (Processing method using the processing auxiliary tool in Figure 20) Next, an example of a processing method for processing a workpiece using the processing machine of Fig. 18 or the processing machine stand of Fig. 19 and the processing auxiliary tool of Fig. 20 will be described with reference to Figs. 21 to 24. Here, as an example, a processing method for manufacturing a workpiece having the same shape as the shape of the mold part of the processing auxiliary tool from the workpiece will be described. In the following explanation, for ease of understanding, the drawings will show only the processing tool 11, table 14, and protrusion 16 on the processing machine side, and only the main body 20, mold portion 21, buffer layer 22, and processing material 26 on the processing auxiliary tool side.

[0092] First, as shown in FIG. 21, the workpiece 26 is mounted and fixed on the processing aid. After that, the user holds the handle of the processing aid and moves the processing aid onto the table 14 of the processing machine or the processing machine stand. At this time, the processing surface of the workpiece 26 mounted on the processing aid is in contact with the upper surface of the table 14, and a part of the outer shape of the uppermost mold part 21 (cutting start point) is in contact with the protruding part 16. In this state, the processing machine is driven to rotate the processing tool 11 (to make it in a cutting possible state). Next, the processing machine is operated to move the tip (blade part) of the processing tool 11 upward to start cutting the workpiece 26. In addition, the tip of the processing tool 11 is further moved upward to penetrate the workpiece 26 (cutting out). Here, since the buffer layer 22 exists as the top of the workpiece 26, even if the tip of the processing tool 11 penetrates the workpiece 26, the processing aid is not damaged.

[0093] Next, as shown in Figures 22 and 23, the user operates the processing auxiliary tool in the left-right and front-back directions to move the protrusion 16 of the processing machine from the cutting start point to the shape (outer shape) of the mold part 21 of the processing auxiliary tool until it returns to the cutting start point again (to the cutting end point). At this time, the protrusion 16 of the processing machine moves along the shape of the mold part 21 of the processing auxiliary tool. Similarly, the processing tool 11 having the same main axis AX as the axis of the protrusion 16 also moves along the shape of the mold part 21. Therefore, as shown in Figure 22 (cutting midpoint) and Figure 23 (cutting end point), it is possible to move the processing tool 11 of the processing machine to the same shape as the mold part 21 of the processing auxiliary tool.

[0094] As a result, as shown in FIG. 24, a workpiece 26g having the same shape (outer shape) as the shape of the die portion 21 of the processing auxiliary tool can be manufactured from the workpiece 26.

That is, the present invention extends to the scope of the present invention that is equivalent to these disclosures, and further to the scope that a person skilled in the art can easily arrive at.

[0096] For example, the present invention can be easily applied to handy types of processing machines such as drill presses, milling machines, routers, trimmers, etc. In recent years, due to the popularity of DIY, there are also small power tools such as mini-routers that can be held like a pen. By attaching such power tools to the processing machine stand of the present invention, even amateurs can cut materials with high precision (including grinding, cutting, engraving, etc.). For example, it becomes possible to easily assemble plastic models and make parts, make parts for handmade accessories, replicate miniature goods, engrave letters and illustrations on glass, create fishing lures, replicate dies, etc.

[0097] (Patentability of the Invention) The processing machine according to the present invention is characterized in that it is equipped with a protrusion for positioning the processing tool to move it in the same shape as the mold part of the processing auxiliary tool relative to the workpiece. The processing machine stand according to the present invention is also characterized in that it is equipped with a similar protrusion. The protrusion equipped to such a processing machine or processing machine stand is novel, and in consideration of the remarkable effect that anyone can manually produce high-precision workpieces in response to needs such as small-lot, high-mix production and production of only a few identical items, it is also fully inventive.

[0098] The processing auxiliary tool according to the present invention is characterized in that it is provided with a template mold part for moving the processing tool in a predetermined direction relative to the workpiece when processing the workpiece using the processing machine or processing machine stand. The mold part provided on such a processing auxiliary tool is new, and also has sufficient inventive step, considering the remarkable effect that anyone can manually produce high-precision workpieces in response to needs such as small-lot, high-mix production and production of only a few identical items, as described above.

[0099] Therefore, the processing machine, processing machine stand, and processing auxiliary tool according to the present invention are all fully patentable.

[0100] (Conclusion) As described above, according to each embodiment of the present invention, it is possible to realize a processing machine, a processing machine stand, and a processing auxiliary tool that can ensure high precision manually even without NC functions. This makes it possible to process small quantities of a wide variety of products or several identical items without increasing costs. Although several embodiments of the present invention have been described, these embodiments are merely presented as examples and are not intended to limit the scope of the present invention. Since these embodiments can be implemented in various other forms, the present invention can be variously omitted, replaced, modified, etc., without departing from the gist of the invention. Therefore, the present invention extends to the invention and its equivalents defined by the invention-specifying matters described in the claims. [Explanation of symbols]
