Description

Technical Field

[0001] The invention relates to the technical field of milling machines, in particular to a milling machine with a lifting platform and a use method thereof. Background Art

[0002] A milling machine is a machine tool that uses a milling cutter to process various surfaces of a workpiece. It uses the rotary cutting of the tool on the surface of the workpiece to produce the required shape, size and position accuracy on the workpiece surface. The milling machine drives the tool to rotate and cut through the spindle, and at the same time the workpiece or milling cutter performs feed motion to achieve the processing of the workpiece surface. During the cutting process, the rotary motion of the tool generates cutting force, which cuts off the metal layer on the workpiece to achieve the processing purpose. Milling machines are widely used in machinery manufacturing, aerospace, automobile manufacturing, mold manufacturing and other fields. It can process various metal and non-metal materials, such as steel, iron, aluminum, copper, plastic, etc., to meet the processing needs of different industries. It has the advantages of high processing accuracy, wide processing range, high production efficiency and strong adaptability. The milling machine with lifting function adopts digital control technology, which can accurately control the feed speed and depth of the milling cutter, thereby achieving high-precision processing. Its CNC system can automatically identify the processing program and adjust it according to different metal materials and processing requirements to ensure processing accuracy. The milling cutter of the lifting table milling machine can move up and down to achieve processing of different depths. In addition, by replacing different milling cutters and accessories, it can realize the processing of workpieces of different materials and complex shapes, enhancing the flexibility of processing. The lifting table milling machine can realize various processing methods and parameter settings through programming, which is convenient and fast.

[0015] The present invention also discloses a method for using a milling machine with a lifting platform, which further includes the following steps, wherein: S1. Before using the milling machine, first conduct a safety check to ensure that all parts of the machine are normal and free of abnormal wear or looseness. Wear protective equipment such as work clothes, safety helmets and protective glasses. At the same time, clamp the workpiece correctly on the workbench and adjust the position to ensure stability and ease of processing.

[0016] S2. Start the milling machine power supply and control system to make the spindle run normally. Then perform the tool setting operation, use the edge finder or the tool setting bite at the bottom of the tool to make the tool parallel to the workpiece surface or reach the required accuracy, and input the measured coordinate value into the machine tool workpiece coordinate system.

[0017] S3. Set appropriate cutting parameters according to the workpiece material and tool type.

[0018] S4. Select the appropriate processing mode. In manual mode, control the machine tool through the manual operating device to perform trial cutting or adjustment. After confirmation, start automatic operation. The machine tool will automatically cut according to the set processing program.

[0019] S5. After the processing is completed, turn off the machine tool spindle motor and control system, return the tool to its original position, clean the processing area and the machine tool surface, and perform necessary maintenance work, such as cleaning the cutting fluid and checking the tool wear. Finally, turn off the machine tool power and leave the operation site.

[0020] The present invention has the following beneficial effects: 1. The milling machine with a lifting platform and the method for using the same drive assembly drive the telescopic housing to slide to the left, thereby driving the telescopic housing, the telescopic inner rod, the second rotating rod, and the T-shaped oil outlet block to slide to the left synchronously. Due to the rotation design between the telescopic inner rod and the second rotating rod, and the spiral design of the spiral groove and the spiral slider, the T-shaped oil outlet block is extended in a rotating manner. The extension of the T-shaped oil outlet block can drive the oil outlet on the side wall of the T-shaped oil outlet block to spray lubricating oil around the T-shaped oil outlet block. The design of the spiral groove and the spiral slider makes the T-shaped oil outlet block Rotary spraying, this design further improves the spraying range of the T-shaped oil outlet block and ensures the coverage of the lubricating oil on the surface of the lifting track groove. Since there are multiple groups of oil outlet components, telescopic outer shells, and telescopic inner rods, each group is connected by a synchronous connecting rod to achieve synchronous movement. The design of the limit sliding groove and the limit sliding rod ensures the stability of each group of components when sliding. At the same time, when the synchronous connecting rod slides to the left, since a piston plate is connected to one side of the synchronous connecting rod, the piston plate will squeeze the space in the oil tank and supply the lubricating oil in the oil tank to the T-shaped oil outlet block through the hose and the one-way oil outlet channel.

[0021] 2. The milling machine with a lifting platform and the method of using the same, each time the lifting slider slides to the top of the lifting track groove, the lifting slider resists the one-way drive rack and slides upward, at which time the one-way drive rack drives the No. 1 one-way gear to rotate, and when the lifting slider slides downward, the one-way drive rack slides downward under the action of the one-way spring, and at this time, due to the one-way design between the one-way drive rack and the No. 1 one-way gear, the one-way drive rack will not drive the No. 1 one-way gear to rotate in the opposite direction during the descent process, so the No. 1 one-way gear and the connecting rod and worm fixedly connected thereto can only rotate in one direction, and the cross design of the No. 1 rotating groove and the connecting rod ensures that the connecting rod and the worm will not appear The horizontal displacement ensures the stability of the transmission. During the rotation of the worm, the worm wheel will drive the worm wheel to rotate synchronously. Since the bottom of the worm wheel is connected to the No. 1 pulley through the torsion spring and the No. 1 rotating rod, and due to the self-locking function of the worm wheel and the worm and the locking of the No. 1 pulley by the release device, the worm wheel cannot rotate in the opposite direction. Therefore, each rotation of the worm wheel will drive the torsion spring to accumulate energy. After the worm wheel rotates one circle, the restriction on the No. 1 pulley is released through the movement of the release device, allowing the No. 1 pulley to rotate. Through this design, the lifting slider can drive the T-shaped oil outlet block to discharge oil after sliding several times, which effectively saves oil consumption and avoids unnecessary waste.

[0022] 3. The milling machine with a lifting platform and the method of using the same, when the lifting slider is at the top, the lifting slider slides to the right against the No. 1 sliding rack, and drives the No. 2 sliding rack to slide to the left through the transmission of the anti-stuck gear. At this time, one side of the No. 2 sliding rack will not contact the limiting plate, and the telescopic shell at the bottom of the limiting plate can slide left and right normally. When the lifting slider does not contact the No. 1 sliding rack, the No. 1 sliding rack slides to the right driven by the No. 2 reset spring, and one end of the No. 2 sliding rack will contact the limiting plate. At this time, the limiting plate The telescopic shell at the bottom will not be able to slide, thereby ensuring that the T-shaped oil outlet block cannot extend. Through this design, it is ensured that when the lifting slider is in the sliding process, the T-shaped oil outlet block will not extend outward under any circumstances, and when the lifting slider is at the top, the No. 2 sliding rack does not restrict the telescopic shell, and the T-shaped oil outlet block can extend freely at this time. Through this design, it is effectively guaranteed that the lifting slider will not be affected by the T-shaped oil outlet block during the sliding process, causing the lifting slider to be unable to slide normally, thereby ensuring the stability of normal operation of the device.

[0036] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0037] Embodiment 1: This embodiment is intended to help solve the problem that when the slider slides inside the slide groove, there may be a blockage or jamming phenomenon at the contact interface between the slider and the slide groove. Figures 1 to 12 .

[0038] A milling machine with a lifting platform comprises a working device 1, wherein the working device 1 comprises a working table 11, a gantry 12 is fixedly connected to the upper surface of the working table 11, a lifting track groove 16 is provided in the gantry 12, a lifting slider 17 is slidably connected in the lifting track groove 16, a working plate 14 is fixedly connected between the lifting sliders 17, a milling machine processing equipment 13 is fixedly connected to the bottom of the working plate 14, an output end of a lifting cylinder 15 is fixedly connected to the upper surface of the working plate 14, the lifting cylinder 15 is installed at the upper end of the gantry 12, and an oil outlet assembly 5 is provided on the side wall of the lifting track groove 16.

[0039] The workbench 11 and the gantry 12 provide support for the lifting and lowering of the milling machine processing equipment 13. The lifting cylinder 15 is used to drive the milling machine processing equipment 13 to slide up and down. The working plate 14, the lifting track groove 16 and the lifting slider 17 ensure the stability of the milling machine processing equipment 13 during the lifting process (the working principle and internal components of the milling machine processing equipment 13 are prior art, so this solution will not be described in detail). The design of the oil outlet component 5 enables the lifting slider 17 to drive the T-shaped oil outlet block 52 to spray lubricating oil onto the inner wall of the lifting track groove 16 after lifting several times, so as to ensure the smooth sliding of the lifting slider 17 in the lifting track groove 16 and prevent blockage.

[0040] The oil outlet assembly 5 includes a T-shaped installation groove 51 provided in the gantry 12 . A T-shaped oil outlet block 52 is installed in the T-shaped installation groove 51 . The interior of the T-shaped oil outlet block 52 is communicated with the oil bin 57 .

[0041] The opening of the T-shaped mounting groove 51 makes the surface of the T-shaped oil outlet block 52 flush with the lifting track groove 16, preventing the lifting slider 17 from being affected by the T-shaped oil outlet block 52 during the descending process. The interior of the T-shaped oil outlet block 52 is hollow in design, and the side wall of the T-shaped oil outlet block 52 is provided with a small nozzle for spraying lubricating oil. The oil outlet on the surface of the T-shaped oil outlet block 52 is provided with items such as cotton that can slow down the spraying force. Through this design, it can be ensured that the lubricating oil on the surface of the T-shaped oil outlet block 52 that is flush with the lifting track groove 16 is seeped out, preventing the lubricating oil from being unable to cover the surface of the lifting track groove 16 due to excessive oil discharge force. The side wall of the T-shaped oil outlet block 52 is provided with a normal nozzle to increase the spraying range of the side wall of the T-shaped oil outlet block 52, and ensure that the inner wall of the lifting track groove 16 is covered with lubricating oil.

[0042] The oil outlet assembly 5 includes a No. 2 rotating groove 53 opened at the bottom of the T-shaped oil outlet block 52, and a No. 2 rotating rod 54 is rotatably connected in the No. 2 rotating groove 53. A one-way oil outlet channel 55 is opened in the No. 2 rotating rod 54 and the T-shaped oil outlet block 52. The one-way oil outlet channel 55 is connected to a hose 56. One end of the hose 56 is fixedly connected to the side wall of the No. 2 rotating rod 54, and the other end of the hose 56 is connected to an oil tank 57. The oil tank 57 is fixedly connected in the movable groove 31. A piston plate 58 is slidably connected in the oil tank 57, and a one-way oil inlet pipeline 59 is opened in the oil tank 57.

[0043] The gantry 12 is provided with a spiral groove 510 at the T-shaped installation groove 51 , in which a spiral slider 511 is slidably connected, and the spiral slider 511 is fixedly connected to the side wall of the T-shaped oil outlet block 52 .

[0044] The sliding of the piston plate 58 and the T-shaped oil outlet block 52 is driven by the pushing assembly 6, which includes a tooth block 62 meshing with the driving gear 312, the tooth block 62 is fixedly connected to one side of the telescopic shell 61, and a telescopic inner rod 63 is slidably connected in the telescopic shell 61. The telescopic inner rod 63 is elastically connected to the telescopic shell 61 through a telescopic spring 64. The oil outlet assembly 5, the telescopic shell 61, the telescopic inner rod 63, and the telescopic spring 64 are provided in multiple groups, and several telescopic shells 61 are connected through a synchronous connecting rod 65. One side of the synchronous connecting rod 65 is fixedly connected to a limit slide 67, and the other end of the limit slide 67 is slidably connected in a limit sliding groove 66. The limit sliding groove 66 is provided in the gantry 12, and the limit slide 67 is connected to the limit sliding groove 66 through a limit spring 68. The side wall of the synchronous connecting rod 65 is fixedly connected to the piston plate 58.

[0045] Each time the lifting slider 17 slides, it will conflict with the driving component 2 at the top of the lifting track groove 16. Through the driving of the driving component 2 and the restriction of the power storage transmission component 3 and the release device 4, the oil outlet component 5 is driven by the pushing component 6 to spray oil to the inner wall of the lifting track groove 16 after the lifting slider 17 slides and conflicts for several times. The drive assembly 2 is driven by the force transmission assembly 3 to drive the telescopic housing 61 to slide to the left, thereby driving the telescopic housing 61, the telescopic inner rod 63, the second rotating rod 54, and the T-shaped oil outlet block 52 to slide to the left synchronously. Due to the rotation design between the telescopic inner rod 63 and the second rotating rod 54, and the spiral design of the spiral groove 510 and the spiral slider 511, the T-shaped oil outlet block 52 is extended in a rotational manner. The extension of the T-shaped oil outlet block 52 can drive the oil outlet on the side wall of the T-shaped oil outlet block 52 to spray lubricating oil around the T-shaped oil outlet block 52. The design of the spiral groove 510 and the spiral slider 511 makes the T-shaped oil outlet block 52 rotate and spray. This design further improves the spraying range of the T-shaped oil outlet block 52, and ensures the coverage of the lubricating oil on the surface of the lifting track groove 16. Since the oil outlet assembly 5 and the telescopic outer shell 61 and the telescopic inner rod 63 are provided in multiple groups, each group is connected by a synchronous connecting rod 65 to achieve synchronous movement. The design of the limiting sliding groove 66 and the limiting sliding rod 67 ensures the stability of each group of components when sliding. At the same time, when the synchronous connecting rod 65 slides to the left, since one side of the synchronous connecting rod 65 is connected to the piston plate 58, the piston plate 58 will squeeze the space in the oil tank 57, and the lubricating oil in the oil tank 57 is supplied to the T-shaped oil outlet block 52 through the hose 56 and the one-way oil outlet channel 55. After spraying, the lifting track groove 16 descends. At this time, the driving component 2 no longer drives the telescopic shell 61. At this time, the telescopic shell 61 and other components will slide to the right under the drive of the limit spring 68. At the same time, since a one-way oil inlet pipe 59 is provided on one side of the oil tank 57, the other end of the one-way oil inlet pipe 59 is connected to the oil supply component through a pipe, and the one-way design of the one-way oil outlet channel 55 and the one-way oil inlet pipe 59 makes it possible to supply oil to the T-shaped oil outlet block 52 when the piston plate 58 slides to the left, and to absorb oil from the oil supply component through the one-way oil inlet pipe 59 when the piston plate 58 slides to the right. This design ensures that the oil tank 57 is always full of lubricating oil, so as to ensure the supply of lubricating oil.

[0046] In order to limit the sliding distance of the milling machine processing equipment 13 each time, a stopper is usually set in the lifting track groove 16 (prior art, not marked), but the position of the stopper may be adjusted at any time. When the stopper is set on the surface of a T-shaped oil outlet block 52, the T-shaped oil outlet block 52 here will not be able to slide outward. Therefore, through the telescopic design of the telescopic outer shell 61 and the telescopic inner rod 63, the T-shaped oil outlet block 52 here cannot be extended, while ensuring that the telescopic outer shell 61 and other groups of T-shaped oil outlet blocks 52 can operate normally to prevent jamming.

[0047] Embodiment 2: This embodiment is intended to promote the solution of the problem that each time the lifting slider 17 is lifted, the T-shaped oil outlet block 52 is driven to discharge oil, resulting in the T-shaped oil outlet block 52 discharging oil too frequently. This embodiment is an explanation based on the embodiment 1. For details, please refer to Figures 1 to 12 .

[0048] A driving assembly 2 is provided inside the upper part of one side of the gantry 12, and the driving assembly 2 includes a driving groove 21 opened in the gantry 12, a one-way driving rack 22 is slidably connected in the driving groove 21, and the one-way driving rack 22 is meshedly connected with a one-way gear 23 No. 1, and a one-way spring 26 is fixedly connected to the top of the one-way driving rack 22, and the other end of the one-way spring 26 is fixedly connected in the driving groove 21, and a connecting rod 25 is fixedly connected to one side of the No. 1 one-way gear 23, and the connecting rod 25 is rotatably connected in the No. 1 rotating groove 24, and the No. 1 rotating groove 24 is opened in the gantry 12, and the other end of the connecting rod 25 is provided with a power storage transmission assembly 3.

[0049] The power storage transmission component 3 includes a movable groove 31 opened in the gantry 12, a connecting rod 25 is fixedly connected to a worm 32 at one end away from the No. 1 one-way gear 23, a side wall of the worm 32 is connected to a worm wheel 33, a No. 1 rotating groove 34 is opened at the bottom of the worm wheel 33, a No. 1 rotating groove 34 is rotatably connected to a No. 1 rotating rod 35, the No. 1 rotating rod 35 and the No. 1 rotating groove 34 are connected by a torsion spring 36, the bottom of the No. 1 rotating rod 35 is fixedly connected to a No. 1 pulley 37, the bottom of the No. 1 pulley 37 is rotatably connected to a No. 1 fixed shaft 38, and the No. 1 fixed shaft 38 is fixedly connected to the inner wall of the gantry 12.

[0050] Through the design of the driving component 2, the power storage transmission component 3 and the release device 4, the lifting slider 17 can drive the T-shaped oil outlet block 52 to discharge oil only after sliding several times. Through this design, oil consumption is effectively saved and unnecessary waste is avoided.

[0051] Each time the lifting slider 17 slides to the top of the lifting track groove 16, the lifting slider 17 resists the one-way drive rack 22 and slides upward. At this time, the one-way drive rack 22 drives the No. 1 one-way gear 23 to rotate. When the lifting slider 17 slides downward, the one-way drive rack 22 slides downward under the action of the one-way spring 26. At this time, due to the one-way design between the one-way drive rack 22 and the No. 1 one-way gear 23, the one-way drive rack 22 will not drive the No. 1 one-way gear 23 to rotate in the opposite direction during the descent process. Therefore, the No. 1 one-way gear 23 and the connecting rod 25 and the worm 32 fixedly connected thereto can only rotate in one direction. The cross design of the No. 1 rotating groove 24 and the connecting rod 25 ensures that the connecting rod 25 and the worm 32 will not be displaced in the horizontal direction, thereby ensuring the stability of the transmission.

[0052] During the rotation of the worm gear 32, the worm wheel 33 is driven to rotate synchronously. Since the bottom of the worm wheel 33 is connected to the No. 1 pulley 37 through the torsion spring 36 and the No. 1 rotating rod 35, and due to the self-locking function of the worm wheel 33 and the worm gear 32 and the locking of the No. 1 pulley 37 by the release device 4, the worm wheel 33 cannot rotate in the opposite direction. Therefore, each rotation of the worm wheel 33 drives the torsion spring 36 to accumulate energy. After the worm wheel 33 rotates one circle, the movement of the release device 4 releases the restriction on the No. 1 pulley 37, allowing the No. 1 pulley 37 to rotate. Through this design, the lifting slider 17 can drive the T-shaped oil outlet block 52 to discharge oil after sliding several times, which effectively saves oil consumption and avoids unnecessary waste.

[0053] A release device 4 is provided at the bottom of the worm gear 33 and the No. 1 pulley 37, and the release device 4 includes a locking groove 41 opened at the bottom of the No. 1 pulley 37, a pointed slide bar 42 is inserted in the locking groove 41, the bottom of the pointed slide bar 42 is slidably connected in the slide groove 43, the slide groove 43 is opened in the gantry 12, a release spring 44 is fixedly connected to the bottom of the pointed slide bar 42, the other end of the release spring 44 is fixedly connected in the slide groove 43, a side wall of the pointed slide bar 42 is provided with a trapezoidal inclined groove 45, the trapezoidal inclined groove 45 is resisted by one end of a release folding rod 46, and the other end of the release folding rod 46 is fixedly connected to the bottom of the worm gear 33.

[0054] The bottom of the first pulley 37 is restricted from rotating by the insertion of the locking groove 41 and the pointed slide bar 42. During the rotation of the worm gear 33, the release folding rod 46 located at the bottom of the worm gear 33 will abut the trapezoidal inclined groove 45 on the side wall of the pointed slide bar 42, thereby driving the pointed slide bar 42 to slide downward and compress the release spring 44, thereby driving the first pulley 37 to rotate normally. When the worm gear 33 continues to slide until the release folding rod 46 does not abut the trapezoidal inclined groove 45, the pointed slide bar 42 will slide upward under the action of the release spring 44 and be reinserted into the locking groove 41 at the bottom of the first pulley 37. There are several locking grooves 41 at the bottom of the first pulley 37, and they are arranged circumferentially with the central axis of the first pulley 37 as the axis. Through this design, the T-shaped oil outlet block 52 can be driven to discharge oil every time the worm gear 33 rotates one circle. This indirect design saves oil consumption and avoids unnecessary waste.

[0055] The inner wall of the gantry 12 is rotatably connected to the second fixed shaft 39, and the side wall of the second fixed shaft 39 is provided with a second pulley 311. The second pulley 311 and the first pulley 37 are connected through a transmission belt 310. One end of the second fixed shaft 39 is fixedly connected to a driving gear 312, and the inner wall of the second pulley 311 is fixedly connected to the first ratchet 313. The first ratchet 313 is meshedly connected to the second ratchet 314, and the second ratchet 314 is fixedly connected to the outer wall of the second fixed shaft 39.

[0056] The first pulley 37 is connected to the second pulley 311 through the transmission belt 310. When the second pulley 311 rotates, it drives the driving gear 312 to rotate through the connection between the second fixed shaft 39 and the driving gear 312, thereby driving the telescopic housing 61 to slide. However, after the torsion spring 36 releases the elastic force, the first pulley 37 will be restricted by the release device 4 again. At this time, the second fixed shaft 39 and the second pulley 311 will not be able to rotate. At this time, the telescopic housing 61 will slide in the reverse direction under the action of the limit spring 68, thereby driving the driving gear 312 in the reverse direction. Rotation, therefore, a first ratchet 313 and a second ratchet 314 are arranged between the second fixed shaft 39 and the second pulley 311. Through the one-way design of the first ratchet 313 and the second ratchet 314, when the driving gear 312 and the second fixed shaft 39 are driven by the limit spring 68 to rotate in the opposite direction, the second pulley 311 will not be driven to rotate. At the same time, this one-way design will not affect the rotation of the driving gear 312 driven by the second pulley 311. Through this design, the transmission system is effectively prevented from being stuck, and the stability of the transmission system transmission is effectively guaranteed.

[0057] Embodiment 3, this embodiment is intended to promote the solution of the problem that when the lifting slider 17 slides downward, the T-shaped oil outlet block 52 may still be in an extended state, affecting the sliding of the lifting slider 17. This embodiment is an explanation based on the embodiment 2. For details, please refer to Figures 1 to 12 .

[0058] An anti-stuck component 7 is provided in the gantry 12, and the anti-stuck component 7 includes an anti-stuck mounting groove 71 opened in the gantry 12, and a No. 1 sliding rack 72 and a No. 2 sliding rack 75 are slidably connected in the anti-stuck mounting groove 71, and the No. 1 sliding rack 72 and the No. 2 sliding rack 75 are connected by an anti-stuck gear 74, and the anti-stuck gear 74 is rotatably connected in the anti-stuck mounting groove 71, and the No. 1 sliding rack 72 is connected to the anti-stuck mounting groove 71 through a No. 1 return spring 73, and the No. 2 sliding rack 75 is connected to the anti-stuck mounting groove 71 through a No. 2 return spring 76, and one end of the No. 2 sliding rack 75 is in contact with a limiting plate 77, and the limiting plate 77 is fixedly connected to the upper surface of the telescopic shell 61.

[0059] In order to prevent the extended T-shaped oil outlet block 52 from affecting the sliding of the lifting slider 17, when the lifting slider 17 is at the top, the lifting slider 17 resists the No. 1 sliding rack 72 to slide to the right, and drives the No. 2 sliding rack 75 to slide to the left through the transmission of the anti-stuck gear 74. At this time, one side of the No. 2 sliding rack 75 will not resist the limiting plate 77. At this time, the telescopic shell 61 at the bottom of the limiting plate 77 can slide left and right normally. When the lifting slider 17 does not resist the No. 1 sliding rack 72, the No. 1 sliding rack 72 slides to the right under the drive of the No. 2 return spring 76. At this time, one end of the No. 2 sliding rack 75 will resist the limiting plate 77. This design ensures that the T-shaped oil outlet block 52 will not extend outward under any circumstances when the lifting slider 17 is in the sliding process, and when the lifting slider 17 is at the top, the No. 2 sliding rack 75 does not restrict the telescopic shell 61, and the T-shaped oil outlet block 52 can extend freely at this time. This design effectively ensures that the lifting slider 17 will not be affected by the T-shaped oil outlet block 52 during the sliding process, resulting in the lifting slider 17 being unable to slide normally, thereby ensuring the stability of the normal operation of the device.

Wear protective equipment such as work clothes, safety helmets and protective glasses. At the same time, clamp the workpiece correctly on the workbench and adjust the position to ensure stability and ease of processing.

[0061] Start the milling machine power supply and control system to make the spindle run normally. Then perform the tool setting operation, use the edge finder or the tool setting bite at the bottom of the tool to make the tool parallel to the workpiece surface or reach the required accuracy, and input the measured coordinate values ​​into the machine tool workpiece coordinate system.
