Description

Technical Field

[0001] This application relates to the field of machine tool processing technology, and in particular to a five-axis machining center. Background Technology

[0002] When some workpieces need to be machined into curved blades, machining equipment is required.

[0003] The blades that the workpiece needs to be machined into are usually thin-walled structures. During machining, the cutting tool cannot provide flexible machining. The tool presses the workpiece hard, which will affect the cutting force, clamping force, or the vibration and elastic deformation released by its own residual stress. This will lead to a decrease in machining accuracy and make the workpiece scrap easily. Moreover, cutting chips tend to accumulate in the machining area during machining, requiring frequent cleaning. If not cleaned in time, the cutting chips can easily scratch the blade surface, affecting the machining quality of the tool and the blade. Summary of the Invention

[0004] To address the aforementioned problems, this application provides a five-axis machining center.

[0005] The five-axis machining center provided in this application adopts the following technical solution: A five-axis machining center includes a base, a first-direction drive mechanism, a sliding member, a second-direction drive mechanism, a worktable, a rotary table, a rotating mechanism, a vertical machine tool, a third-direction drive mechanism, a swing mechanism, a machining structure, and a tool magazine. The base has a concave structure, and the first-direction drive mechanism is installed inside the base. The sliding member is connected to the drive end of the first-direction drive mechanism and moves along the first direction under drive. The second-direction drive mechanism is installed on the sliding member. The rotary table is connected to the drive end of the second-direction drive mechanism and moves along the second direction under drive. A rotating mechanism is provided on the rotary table to fix the workpiece and drive the workpiece to rotate. The vertical machine tool is installed on the base and is installed vertically. The third-direction drive mechanism is installed on the vertical machine tool. The swing mechanism is connected to the drive end of the third-direction drive mechanism and moves along the third direction under drive. The machining structure is connected to the swing end of the swing mechanism. The tool magazine is installed on the vertical machine tool to store machining tools.

[0006] By adopting the above technical solution, after the workpiece is installed on the rotating mechanism, the sliding part is driven to move along the first direction by the first direction driving mechanism, and the rotating table and rotating mechanism are driven to move along the second direction by the second direction driving mechanism. The cutting tool is installed on the machining structure, and the machining structure is oscillating by the swing mechanism. The swing mechanism is driven by the third direction driving mechanism, which drives the machining structure to move in the third direction, thereby achieving the effect of five-axis linkage machining. By providing flexible machining of the workpiece in multiple directions and angles, the pressure on the workpiece is reduced, and the yield is improved. The workpiece is rotated by the rotating mechanism, thereby dumping the cutting chips into the concave part of the base, avoiding affecting the machining quality of the workpiece.

[0007] Optionally, the first direction drive mechanism, the second direction drive mechanism, and the third direction drive mechanism have the same structure, but differ in their installation position and installation direction.

[0008] By adopting the above technical solution, three different directions provide drive for the orientation of the tool and the workpiece, and the swing mechanism and rotation mechanism enable the workpiece and the tool to obtain flexible processing conditions, reducing the force of the tool pressing or contacting the workpiece.

[0009] Optionally, the base has a chip discharge port, which is equipped with a chip discharge mechanism that runs through the base and drives the cutting chips to be discharged from the chip discharge port.

[0010] By adopting the above technical solution, the chip removal mechanism discharges the cutting chips accumulated on the base towards the chip removal port, so as to avoid a large amount of cutting chips accumulating and being difficult to remove, while without stopping the processing of the workpiece.

[0011] Optionally, the base is equipped with an inclined plate, which is tilted towards the chip removal mechanism.

[0012] By adopting the above technical solution, the inclined plate can use the inclined direction to make the cutting chips slide towards the chip removal mechanism under the action of gravity, thereby improving the chip removal efficiency.

[0013] Optionally, the base is also equipped with a chip-pushing mechanism that moves along the base and pushes the cutting chips toward the chip removal mechanism.

[0014] By adopting the above technical solution, the chip pushing mechanism can push stubborn cutting chips to the chip removal mechanism, thereby improving chip removal efficiency.

[0015] Optionally, the chip-pushing mechanism includes a support plate, a chip-pushing drive unit, a first drive wheel, a second drive wheel, a linkage belt, the chip-pushing part, and a load-bearing rail; the support plate is installed along the side of the base; the chip-pushing drive unit is installed on the support plate, and its drive end extends outward through the support plate; the first drive wheel is connected to the drive end of the chip-pushing drive unit, and the second drive wheel is installed on the side of the support plate away from the chip-pushing drive unit; the linkage belt is sleeved between the first drive wheel and the second drive wheel; the chip-pushing part is connected to the linkage belt; the load-bearing rail is located on the other side of the base, and the chip-pushing part slides through the base plate and is slidably connected to the load-bearing rail.

[0016] By adopting the above technical solution, one end of the chip pusher is slidably connected to the load-bearing rail, and the other end is connected to the linkage belt. The chip pusher drive unit drives the first drive wheel to rotate, and the linkage belt drives the second drive wheel to rotate. The linkage belt rotates synchronously, and during the rotation, the chip pusher moves along the load-bearing rail. The chip pusher contacts the base or inclined plate, thereby pushing the cutting chips on the base or inclined plate towards the chip removal mechanism, so as to facilitate the cleaning of stubborn cutting chips and prevent accumulation.

[0017] Optionally, the support plate is also provided with a guide groove, and the chip pusher is slidably connected to the guide groove.

[0018] By adopting the above technical solution, the chip pusher is slidably connected to the guide groove, so that the chip pusher can be supported by the bearing plate, and the linkage belt only provides a pulling effect, so as to ensure the stable movement of the chip pusher.

[0019] Optionally, the base is also equipped with a chip-blocking mechanism, which is located at the initial position of the chip-pushing part and connected to the chip-pushing part.

[0020] By adopting the above technical solution, when the chip pusher moves toward the chip removal mechanism, the chip blocking mechanism blocks the area that the chip pusher has moved through, thereby preventing the cutting chips from falling onto the base.

[0021] Optionally, the chip-blocking mechanism includes a pivot frame, a pivot shaft, a winding drive unit, a roll, and a shielding cloth; two sets of pivot frames are provided, respectively installed on both sides of the base, and a pivot shaft is provided between the two sets of pivot frames; the winding drive unit is installed on one of the pivot frames, and the drive end is connected to the pivot shaft; the roll is sleeved and installed on the pivot shaft, and rotates with the pivot shaft; one end of the shielding cloth is wound into the roll, and the other end is connected to the chip-pushing unit.

[0022] By adopting the above technical solution, when the chip pusher moves, it pulls the shielding cloth to unfold. The shielding cloth drives the drum and pivot shaft to rotate and unwind. As the chip pusher moves, the moved position is covered by the continuously unfolding shielding cloth. When the cutting chips fall, they fall on the shielding cloth and cannot fall to the base or inclined plate.

[0023] Optionally, the pivot frame is also equipped with a recovery trough located below the drum.

[0024] By adopting the above technical solution, when the shielding cloth is being rolled up, the stubborn cutting chips attached to the shielding cloth will be rolled up along with the shielding cloth until it reaches the roll. At the end of the roll, the shielding cloth will pour the cutting chips into the recycling tank, so as to facilitate the recycling of excess cutting chips.

[0025] In summary, this application includes at least one of the following beneficial technical effects: 1. After the workpiece is installed on the rotating mechanism, the sliding part is driven to move along the first direction by the first direction driving mechanism, and the rotating table and rotating mechanism are driven to move along the second direction by the second direction driving mechanism. The tool is installed on the machining structure, and the machining structure is oscillating by the swing mechanism. The swing mechanism is driven by the third direction driving mechanism, which drives the machining structure to move in the third direction, realizing the effect of five-axis linkage machining. By providing flexible machining of the workpiece in multiple directions and angles, the pressure on the workpiece is reduced and the yield is improved. The workpiece is rotated by the rotating mechanism, thereby dumping the cutting chips into the concave part of the base to avoid affecting the machining quality of the workpiece. 2. Three different directions provide drive for the orientation of the tool and the workpiece, and together with the swing mechanism and the rotation mechanism, the workpiece and the tool can obtain flexible processing conditions, reducing the force of the tool pressing or contacting the workpiece. 3. The chip removal mechanism is used to discharge the cutting chips accumulated on the base towards the chip removal port, so as to avoid a large accumulation of cutting chips that are difficult to remove, and at the same time, the workpiece processing can be stopped. 4. The inclined plate can use its tilt to make the cutting chips slide towards the chip removal mechanism under the action of gravity, thereby improving chip removal efficiency.

[0032] The following is in conjunction with the appendix Figure 1 -Appendix Figure 5 This application will be described in further detail below.

[0033] This application discloses a five-axis machining center.

[0034] A five-axis machining center, reference Figure 1 As shown, it includes a base 1, a first direction drive mechanism 2, a sliding member 3, a second direction drive mechanism 4, a worktable 5, a rotating table 6, a rotating mechanism 7, a vertical machine base 8, a third direction drive mechanism 9, a swing mechanism 10, a machining structure, and a tool magazine 12; the base 1 has a concave structure, that is, an inner groove is provided in the base 1 to provide for the accumulation of cutting chips and prevent the oblique chips from affecting the cutting of the blades; the first direction drive mechanism 2 is installed in the base 1.

[0035] The sliding member 3 is connected to the driving end of the first direction driving mechanism 2. The sliding member 3 can be a saddle or a bed saddle, and can move along the first direction under the drive of the first direction driving mechanism 2.

[0036] The second direction drive mechanism 4 is installed on the top of the slider 3. Therefore, the second direction drive mechanism 4 can move along the first direction with the slider 3. The rotating table 6 is connected to the drive end of the second direction drive mechanism 4 and moves along the second direction under the drive. Thus, the rotating table 6 can move synchronously along the first direction or the second direction.

[0037] The rotating table 6 is equipped with a rotating mechanism 7, which can be composed of two sets of rotating motors. The rotating end of the rotating motor can be equipped with a rotating clamp. The rotating mechanism 7 can fix the workpiece and drive the workpiece to rotate, while also driving the workpiece to move along the first direction and the second direction.

[0038] The vertical machine base 8 is installed on the base 1 and is installed in the vertical direction. The third-direction drive mechanism 9 is installed on the vertical machine base 8. The swing mechanism 10 is connected to the drive end of the third-direction drive mechanism 9 and moves in the third direction under the drive. The swing mechanism 10 can be a swing seat and a swing motor. The swing mechanism 10 can follow the third-direction drive mechanism 9 to move in the third direction. Since the vertical machine base 8 is installed in the vertical direction, the third direction can be the vertical direction.

[0039] The machining structure is connected to the swing end of the swing mechanism 10, which is the swing end of the swing motor. The machining structure can swing through the swing end of the swing mechanism 10 to change the machining position in multiple directions. The machining structure can use a tool motor, a tool spindle and a tool holder. The tool motor drives the tool spindle to rotate, and the tool holder is installed on the tool spindle and fixes the tool, so that the tool can be driven to process the workpiece.

[0040] Tool magazine 12 is installed on vertical machine base 8 to provide storage for machining tools, facilitating replacement of tools after prolonged use and damage.

[0041] With the top surface of base 1 as the reference plane, the first direction can be the front-back direction of base 1, the second direction can be the left-right direction of base 1, and the third direction can be the vertical direction of base 1, that is, the X-axis, Y-axis and Z-axis provide three-axis drive.

[0042] The tool magazine 12 may be equipped with a tool changing structure to push the tool out of the tool magazine 12. Since it is not related to the technical issues of this application, it will not be described in detail.

[0043] Specifically, after the workpiece is installed on the rotating mechanism 7, the sliding member 3 is driven to move along the first direction by the first direction driving mechanism 2, and the rotating table 6 and the rotating mechanism 7 are driven to move along the second direction by the second direction driving mechanism 4. The cutting tool is installed on the machining structure, and the machining structure is oscillating by the swing mechanism 10. The swing mechanism 10 is driven by the third direction driving mechanism 9, which drives the machining structure to move in the third direction, thereby achieving the effect of five-axis linkage machining. By providing flexible machining of the workpiece in multiple directions and angles, the pressure on the workpiece is reduced, and the yield is improved. The workpiece is rotated by the rotating mechanism 7, thereby dumping the cutting chips into the concave part of the base 1, avoiding affecting the machining quality of the workpiece.

[0044] Further reference Figure 1As shown, the first direction drive mechanism 2, the second direction drive mechanism 4, and the third direction drive mechanism 9 have the same structure, the difference being the installation position and installation direction. That is, the first direction drive mechanism 2 is installed on the base 1, the second direction drive mechanism 4 is installed on the sliding member 3, and the third direction drive mechanism 9 is installed on the vertical machine table 8. The installation positions are different, and the installation directions are the X-axis, Y-axis, and Z-axis directions. The three different directions provide drive for the orientation of the tool and the workpiece, and together with the swing mechanism 10 and the rotation mechanism 7, the workpiece and the tool can obtain flexible processing conditions, reducing the force of the tool pressing or contacting the workpiece.

[0045] The first direction drive mechanism 2, the second direction drive mechanism 4, and the third direction drive mechanism 9 have the same structure. They can all adopt a motor and lead screw structure, that is, the motor drives the lead screw to rotate, and the sliding rail and threaded part provide limit. The threaded part is screwed to the lead screw and slidably connected to the sliding rail. The motor drives the lead screw to rotate, so that the threaded part moves along the sliding rail. The threaded part can be a nut or a slider with a threaded hole.

[0046] In some embodiments, reference Figure 2 and Figure 3 As shown, the base 1 has a chip discharge port 101, and a chip discharge mechanism 13 is provided inside the chip discharge port 101. The chip discharge mechanism 13 is installed through the base 1 and drives the cutting chips to be discharged from the chip discharge port 101. The chip discharge mechanism 13 discharges the cutting chips accumulated on the base 1 towards the chip discharge port 101 to avoid a large amount of cutting chips accumulating and being difficult to discharge, while not having to stop the processing of the workpiece.

[0047] Furthermore, the base 1 is provided with an inclined plate (not shown in the figure), which is inclined towards the chip removal mechanism 13. Since the inclined plate is an inclined surface with a preset angle, the inclined plate can use the inclined direction to make the cutting chips slide towards the chip removal mechanism 13 under the action of gravity, thereby improving the chip removal efficiency.

[0048] Furthermore, refer to Figure 2 or Figure 3 As shown, the chip removal mechanism 13 includes a chip removal motor 131, a chip removal shaft 132, and a spiral blade 133. The chip removal motor 131 is mounted outside the base 1. The chip removal shaft 132 is connected to the drive end of the chip removal motor 131 and extends through the base 1 from the chip removal port 101. The spiral blade 133 is connected to the chip removal shaft 132. Under the drive of the chip removal motor 131, the spiral motor rotates, thereby driving the cutting chips to be conveyed out of the chip removal port 101 in a spiral direction.

[0049] In some embodiments, reference Figure 3 and Figure 4As shown, the base 1 is also provided with a chip pushing mechanism 14. The chip pushing mechanism 14 moves along the base 1 and pushes the cutting chips toward the chip removal mechanism 13. The chip pushing mechanism 14 is used to push the cutting chips in the base 1 to the chip removal mechanism 13. Since some cutting chips are stubborn or have complex shapes that cannot slide along the inclined plate, or some machining centers are also provided with cooling structures that can spray coolant for cooling, the cutting chips are prone to being attached to water stains and have tension, adhering to the inner wall of the base 1 or the inclined plate. Therefore, the chip pushing mechanism 14 is provided to push the stubborn cutting chips to the chip removal mechanism 13, thereby improving the chip removal efficiency.

[0050] If a chip-pushing mechanism 14 is provided, an inclined plate can be set as needed. If an inclined plate is set, the chip-pushing mechanism 14 needs to be tilted according to the tilt angle of the inclined plate.

[0051] The chip-pushing mechanism 14 is lower than the height of the first direction drive mechanism 2, while the sliding member 3, the second direction drive mechanism 4 and other mechanisms are above the first direction drive mechanism 2. Therefore, the chip-pushing mechanism 14 will push the cutting chips from below the first direction drive mechanism 2 without affecting the operation of other mechanisms.

[0052] Further reference Figure 3 and Figure 4 As shown, the chip-pushing mechanism 14 includes a support plate 141, a chip-pushing drive unit 142, a first drive wheel 143, a second drive wheel 144, a linkage belt 145, a chip-pushing part 146, and a load-bearing rail 147. The support plate 141 is installed along the side of the base 1. A barrier cover can be provided outside the support plate 141 to prevent cutting chips from falling onto the support plate 141. The support plate 141 serves as the support and mounting structure for the overall chip-pushing mechanism 14.

[0053] The chip pushing drive unit 142 is mounted on the support plate 141, and the drive end extends outward through the support plate 141. The chip pushing drive unit 142 can be a chip pushing motor or a chip pushing motor. The support plate 141 can be provided with a through-hole, which extends upward through the support plate 141.

[0054] The first drive wheel 143 is connected to the drive end of the chip-pushing drive unit 142, and the second drive wheel 144 is installed on the side of the support plate 141 away from the chip-pushing drive unit 142. The first drive wheel 143 and the second drive wheel 144 can be of different types depending on the requirements. They can be pulleys or sprockets, and both are composed of a rotating shaft and a wheel body. The rotating shaft of the first drive wheel 143 is connected to the chip-pushing drive unit 142, and the wheel body is fixedly connected to the rotating shaft. The rotating bearing support plate 141 of the second drive wheel 144 is fixedly connected, and the wheel body is pivotally connected to the rotating shaft, so that the first drive wheel 143 can rotate with the chip-pushing drive unit 142, and the second drive wheel 144 can rotate along the rotating shaft.

[0055] The linkage belt 145 is sleeved between the first drive wheel 143 and the second drive wheel 144. When the first drive wheel 143 rotates, the linkage belt 145 drives the second drive wheel 144 to rotate synchronously. The type of linkage belt 145 is determined according to the type of the first drive wheel 143 and the second drive wheel 144. If it is a pulley, the linkage belt 145 is a flat belt; if it is a sprocket, a chain can be used.

[0056] The chip-pushing part 146 is connected to the linkage belt 145. The chip-pushing part 146 can be a pusher frame and a wedge block 1462. The surface of the wedge block 1462 is inclined. The pusher frame spans the base 1, and the wedge block 1462 abuts against the surface of the base 1 or the inclined plate. When the linkage belt 145 rotates with the first drive wheel 143 and the second drive wheel 144, the chip-pushing part 146 moves with the linkage belt 145. The two ends of the bearing plate 141 are located at the two ends of the base 1, so the positions of the first drive wheel 143 and the second drive wheel 144 are also located at the two ends of the base 1, so that the linkage belt 145 can drive the chip-pushing part 146 to move from one end of the base 1 to the other end. The position of the chip removal mechanism 13 corresponds to the position of the second drive wheel 144 or the first drive wheel 143, so that the chip-pushing part 146 can push the cutting chips as a whole to the chip removal mechanism 13.

[0057] The load-bearing rail 147 is located on the other side of the base 1. The chip-pushing part 146 passes through the base plate and is slidably connected to the load-bearing rail 147. The linkage belt 145 connects one end of the chip-pushing part 146 and supports the other end of the chip-pushing part 146 through the load-bearing rail 147, so that the two ends are balanced and the stability of movement is guaranteed.

[0058] If the height of the chip-pushing drive unit 142 is insufficient, a pad can be installed at the bottom of the base 1 to raise the height of the base 1. The chip-pushing drive unit 142 can be installed through the base 1 to meet the height requirements.

[0059] Specifically, one end of the chip-pushing part 146 is slidably connected to the load-bearing rail 147, and the other end is connected to the linkage belt 145. The chip-pushing drive part 142 drives the first drive wheel 143 to rotate, and the linkage belt 145 drives the second drive wheel 144 to rotate. The linkage belt 145 rotates synchronously. During the rotation, the chip-pushing part 146 moves along the load-bearing rail 147. The chip-pushing part 146 contacts the base 1 or the inclined plate, thereby pushing the cutting chips on the base 1 or the inclined plate toward the chip removal mechanism 13, so as to facilitate the cleaning of stubborn cutting chips and prevent accumulation.

[0060] Further reference Figure 4As shown, the support plate 141 is also provided with a guide groove 1411. The chip-pushing part 146 is slidably connected to the guide groove 1411. Since the linkage belt 145 is a soft structure, it is only tensioned by the first drive wheel 143 and the second drive wheel 144. If the friction between the chip-pushing part 146 and the base 1 or the inclined plate is too large, the chip-pushing part 146 will not be able to move smoothly. Therefore, the support plate 141 is provided with a guide groove 1411. The bottom of the chip-pushing part 146 can be provided with guide protrusions or balls to reduce friction. The chip-pushing part 146 slides along the guide groove 1411 and maintains the movement trajectory, so that the chip-pushing part 146 uses the support plate 141 to provide load, and the linkage belt 145 only provides the pulling effect to ensure the stable movement of the chip-pushing part 146.

[0061] In some embodiments, reference Figure 5 As shown, the base 1 is also provided with a chip blocking mechanism 15. The chip blocking mechanism 15 is located at the initial position of the chip pushing part 146 and is connected to the chip pushing part 146. The function of the chip blocking mechanism 15 is that when the chip pushing part 146 is driven to move along the base 1 or the inclined plate towards the chip removal mechanism 13, if the chip falls to the position pushed by the chip pushing part 146 during the movement towards the chip removal mechanism 13, the chip pushing part 146 will return to its reset position and push the chip away from the chip removal mechanism 13, resulting in the inability to recover the chips. Therefore, the chip blocking mechanism 15 is provided so that when the chip pushing part 146 moves towards the chip removal mechanism 13, the chip blocking mechanism 15 blocks the area that the chip pushing part 146 has moved through, thereby preventing the chip from falling onto the base 1 or the inclined plate.

[0062] Further reference Figure 5 As shown, the chip blocking mechanism 15 includes a pivot frame 151, a drum 154, and a shielding cloth 155. There are two sets of pivot frames 151, which are respectively installed on both sides of the base 1. A pivot shaft 152 is provided between the two sets of pivot frames 151. The pivot shaft 152 is set across the base 1. A pivot hole can be opened on the pivot frame 151. The pivot shaft 152 is inserted into the pivot hole and rotates along the pivot hole.

[0063] The winding drive unit 153 is mounted on one of the pivot frames 151, and the drive end is connected to the pivot shaft 152. In the figure, the pivot shaft 152 is covered by the winding drive unit 153 and is therefore represented by a dashed line. The winding drive unit 153 can be a winding motor, which can drive the pivot shaft 152 to rotate for winding.

[0064] The roll 154 is mounted on the pivot shaft 152 and rotates with the pivot shaft 152. One end of the shielding cloth 155 is wound up on the roll 154, and the other end is connected to the chip pusher 146. The shielding cloth 155 is wound on the roll 154 and remains wound up when not unfolded.

[0065] The height of the chip blocking mechanism 15 does not exceed that of the first direction drive mechanism 2, so as to ensure that the chip blocking mechanism 15 will not affect the operation of the sliding member 3 and the mechanism connected thereto. The vertical machine platform 8 can be set on the top of the base 1 and does not contact the ground of the base 1, so it is not within the movement path of the chip blocking mechanism 15 and the chip pushing mechanism 14.

[0066] Specifically, when the chip-pushing part 146 moves, it pulls the shielding cloth 155 to unfold. The shielding part drives the drum 154 and the pivot shaft 152 to rotate and unwind. As the chip-pushing part 146 moves, the moved position is covered by the continuously unfolding shielding cloth 155. When the chips fall, they fall on the shielding cloth 155 and cannot fall to the base 1 or the inclined plate. At the same time, due to the pivot frame 151, the height of the drum 154 is higher than that of the chip-pushing part 146. Therefore, when the chip-pushing part 146 moves, the unfolded shielding part also forms an inclined surface, tilting towards the chip removal mechanism 13. This allows the falling chips to roll down with the shielding cloth 155 onto the chip removal mechanism 13 or the base 1 or the inclined plate in the direction of movement of the chip-pushing part 146.

[0067] When the chip-pushing section 146 finishes pushing the chips, the chip-pushing drive section 142 rotates in the opposite direction, driving the linkage belt 145 to move in the opposite direction, causing the chip-pushing section 146 to move back to the initial position. At this time, the winding drive section 153 rotates synchronously, winding the shielding cloth 155 onto the roll 154.

[0068] A sensor for detecting tension can be connected to the pivot shaft 152. When the chip pusher 146 moves in the opposite direction, the tension of the shielding cloth 155 changes and it no longer has tension. At this time, the sensor can transmit the information to the back-end, and the back-end sends the opening and closing command to the winding drive unit 153.

[0069] Furthermore, refer to Figure 5 As shown, the pivot frame 151 is also provided with a recovery trough 156, which is located below the drum 154. The opening of the recovery trough 156 faces upward, i.e. towards the drum 154, so that when the shielding cloth 155 is being wound up, the stubborn cutting chips attached to the shielding cloth 155 will be wound up along with the shielding cloth 155 until the drum 154 is reached. At this point, the shielding cloth 155 pours the cutting chips into the recovery trough 156, thereby facilitating the recovery of excess cutting chips.
