For ordinary technicians in this field, the specific meanings of the above terms in the present invention can be understood according to specific circumstances.

[0020] In addition, in the description of the present application, the terms "first", "second", etc. are only used to distinguish the description and cannot be understood as indicating or implying relative importance.

[0021] Reference Figure 1, which is the first embodiment of the present invention, proposes a CNC tool, including: a tool base 101, a cutting edge 102 at the top corner of the tool base 101, the cutting edge 102 is used for processing a workpiece, the cutting edge 102 has a concave spherical surface 103, the concave spherical surface 103 is used for chip removal from the cutting edge 102; a protrusion 103, arranged on the tool base 101, the protrusion 103 has a flange 105, the flange 105 is used for chip breaking; a mounting hole 106, which is arranged through the middle of the tool base 101, and the mounting hole 106 is used to mount the tool base 101 on a guide rod.

[0022] In the above scheme, there is a cutting edge 102 at the top corner of the tool base 101, and a concave spherical surface 103 is provided at the cutting edge 102. The concave spherical surface 103 can effectively guide the chips to be discharged smoothly, reduce the accumulation of chips at the cutting edge 102, and thus improve the chip removal effect. The protrusion 103 is provided on the tool base 101, which has a flange 105. The function of the flange 105 is to produce a chip breaking effect during the cutting process, prevent long chips from being entangled on the tool, and improve the processing accuracy and efficiency. Through the mounting hole 106, the tool base 101 can be conveniently installed on the guide rod, which is convenient for use in the machine tool. Specifically, the tool base 101 is made of cemented carbide material to ensure the durability and cutting performance of the tool. A concave spherical surface 103 is provided at the cutting edge 102 at the top corner of the tool base 101, and the curvature radius of the concave spherical surface 103 is designed according to the specific processing requirements to ensure the best chip removal effect. . The diameter and depth of the mounting hole 106 should match the guide rod to ensure that the installation is firm and easy to disassemble. The present invention can effectively improve the chip removal effect and reduce the accumulation of chips at the cutting edge 102 by setting a concave spherical surface 103 at the cutting edge 102, thereby improving the cutting efficiency. The flange 105 of the protrusion 103 can realize the chip breaking function, avoid long chips from being entangled on the tool, and improve the processing accuracy and efficiency. The mounting hole 106 allows the tool to be quickly installed on the guide rod, which is convenient for use in a machine tool and improves production efficiency. The CNC tool 1 of the present invention can significantly improve cutting efficiency and extend the service life of the tool.

[0023] Furthermore, the number of flanges 105 is the same as the number of edge lines of the tool base 101 , and each flange 105 corresponds to one edge line.

[0024] In the above scheme, the CNC tool 1 can be a triangle, rectangle, rhombus or polygon, and the number of flanges 105 is the same as the number of sides of the CNC tool 1, which is convenient for chip breaking. The design that each flange 105 corresponds to a side line can ensure that an effective chip breaking point is formed during the cutting process, avoid long chips from being entangled on the tool, improve processing accuracy and efficiency, and reduce vibration and noise generated during the cutting process by optimizing chip breaking and chip removal effects, thereby improving the finish and overall quality of the processed surface. It can be adjusted according to different processing materials and conditions to achieve the best chip breaking effect.

[0025] Furthermore, the mounting hole 106 is a shrinking hole structure, and the diameter of the mounting hole 106 gradually decreases from the top surface to the bottom surface of the tool base 101.

[0026] In the above scheme, the design of the shrinking hole can increase the contact area between the tool and the guide rod, thereby improving the stability of the tool during use. The gradually shrinking diameter can better fix the tool, reduce the shaking of the tool during high-speed cutting, and improve the processing accuracy.

[0027] Furthermore, the tool substrate 101 is made of cemented carbide.

[0028] In the above scheme, cemented carbide is selected as the main material of the tool substrate 101 because cemented carbide has high hardness, wear resistance and heat resistance. The stability and wear resistance of cemented carbide help to improve processing accuracy and surface finish, and it is very suitable for manufacturing high-quality cutting tools.

[0029] Reference Figure 2~Figure 9 A polishing device for CNC tool processing is used for processing CNC tool 1, including: a workbench 2; a loading device 4, which is arranged on the workbench 2, and the loading device 4 is used to place the CNC tool 1 to be processed; a mechanical arm 3, which is arranged on the workbench 2, and the mechanical arm 3 is used to take the CNC tool 1; a grinding and polishing device 5, which is arranged on the workbench 2; a control device 6, which is arranged on the workbench 2, after the mechanical arm 3 puts the tool to be processed into the control device 6, the control device 6 is close to the grinding and polishing device 5 to process the CNC tool 1.

[0030] In the above scheme, it should be noted that when manufacturing and processing the CNC tool 1, the side of the CNC tool 1 needs to be polished and ground, but the protrusion 103, flange 105 and cutting edge 102 of the CNC tool 1 cannot be polished and ground. Therefore, a polishing device for processing the CNC tool 1 is required to polish and grind the protrusion 103, flange 105 and cutting edge 102 of the CNC tool 1, and can timely discharge the debris particles generated by polishing. The device can accurately polish and grind specific parts of the CNC tool 1, and can timely discharge the debris particles generated during the polishing process, so as to improve the processing efficiency and tool quality.

[0031] Specifically, the workbench 2 is the basic platform of the entire equipment, which is used to carry and position other components. The loading device 4 is arranged on the workbench 2, and is used to place the CNC tool 1 to be processed. The loading device 4 can be a device with a placement area, which can place several CNC tools 1 at the same time. The robot arm 3 is arranged on the workbench 2, and is used to take the CNC tool 1 and place it accurately to a predetermined position. The robot arm 3 can be equipped with a precise positioning system to ensure that the CNC tool 1 can be accurately placed on the control device 6. The grinding and polishing device 5 is arranged on the workbench 2, and is used to polish the CNC tool 1. The control device 6 is arranged on the workbench 2 to control the entire polishing process. When the robot arm 3 puts the tool to be processed into the control device 6, the control device 6 can receive instructions, and the control device 6 adjusts the control by sliding, and starts to process the CNC tool 1 in cooperation with the grinding and polishing device 5. The control device 6 can be integrated with advanced sensors and software algorithms to ensure precise control of the polishing process.

After the telescopic arm 7 moves, the clamp 12 approaches or moves away from the grinding and polishing device 5.

[0033] In the above scheme, the base 8 is arranged on the workbench 2, and as the basic structure of the control device 6, the base 8 has an arc-shaped slide groove 801 for guiding the moving path of the slide 10. Through the arc-shaped slide groove 801 of the base 8, the moving direction of the slide 10 can be accurately controlled, and then the relative position between the CNC tool 1 and the grinding and polishing device 5 can be adjusted. The slide 10 can slide on the arc-shaped slide groove 801 to achieve movement along the arc path. The movement of the slide 10 can adjust the position of the CNC tool 1 relative to the grinding and polishing device 5 to adapt to different polishing requirements. The telescopic arm 7 is horizontally slidably arranged on the slide 10 and has a mounting portion 9. The telescopic arm 7 can be telescopically moved in the horizontal direction to adjust its length. Through the telescopic arm 7, the distance between the CNC tool 1 and the grinding and polishing device 5 can be further adjusted to ensure an accurate polishing process. The clamp 12 is rotatably arranged in the mounting portion 9 of the telescopic arm 7, and is used to clamp the CNC tool 1. The clamp 12 can rotate to adjust the orientation of the CNC tool 1. By rotating the fixture 12, the angle of the CNC tool 1 can be adjusted to ensure that the side of the CNC tool 1 can accurately contact the grinding and polishing device 5 to avoid damaging key parts.

[0034] Specifically, through the combined use of the arc-shaped slide groove 801 of the base 8, the slide 10 and the telescopic arm 7, the position of the CNC tool 1 can be accurately controlled to ensure the accuracy and controllability of the polishing process. The combination of the telescopic arm 7 and the clamp 12 provides additional flexibility and can adapt to CNC tools 1 of different sizes and shapes. By accurately controlling the position of the CNC tool 1, damage to key parts such as the protrusion 103, the flange 105 and the cutting edge 102 can be avoided, ensuring the quality and service life of the tool. In summary, the control device 6 can achieve accurate control and adjustment of the position of the CNC tool 1 through the design of the base 8, the slide 10, the telescopic arm 7 and the clamp 12, ensuring the accuracy and controllability of the polishing process, while protecting the key parts of the tool from damage.

[0036] In the above scheme, the support 1201 has a recessed portion 1202 for accommodating a part of the CNC tool 1. By rotating the support 1201, the position and angle of the CNC tool 1 can be adjusted to meet different polishing requirements. The first pressure rod 13 is fixed on the support 1201 and is used to fix the CNC tool 1. The first pressure rod 13 and the second pressure rod 14 work together to clamp the CNC tool 1. The second pressure rod 14 slides through the other side of the support 1201 and is coaxially arranged with the first pressure rod 13. The second pressure rod 14 can slide along the support 1201, and the CNC tool 1 is clamped by the cooperation of the circular hole groove 1401 and the pressing rod 1301. When the second pressure rod 14 is close to the first pressure rod 13, the circular hole groove 1401 is used to accommodate and squeeze the pressing rod 1301. The pressing rod 1301 cooperates with the circular hole groove 1401 of the second pressure rod 14 to achieve effective clamping of the CNC tool 1 by squeezing the pressing rod 1301. Through the cooperation of the first pressure rod 13 and the second pressure rod 14, and the action of the pressing rod 1301, the CNC tool 1 can be stably clamped, ensuring the stable position of the CNC tool 1 during the polishing process. Through the combined use of the first pressure rod 13, the second pressure rod 14 and the pressing rod 1301, the CNC tool 1 can be accurately clamped, ensuring the stable position of the CNC tool 1 during the polishing process. The sliding design of the second pressure rod 14 allows the CNC tools 1 of different sizes and shapes to be clamped. By accurately controlling the position of the CNC tool 1, damage to key parts such as the protrusion 103, the flange 105 and the cutting edge 102 can be avoided, ensuring the quality and service life of the tool.

[0037] Furthermore, the first pressure rod 13 has a water flow channel 21 inside, and the water flow channel 21 is connected to an external water source. The end face of the first pressure rod 13 close to the second pressure rod 14 has a plurality of water outlet holes 1302, and the plurality of water outlet holes 1302 are arranged along the tangent direction of the end face. The water outlet holes 1302 are connected to the water flow channel 21, and the water outlet holes 1302 are used to transport water to the surface of the CNC tool 1.

After the pressing rod 1301 slides, the water retaining ring 20 blocks or cancels the blocking of the water hole 1901.

[0038] In the above scheme, water is transported to the surface of the CNC tool 1 through the water flow channel 21 to play a role in cooling, cleaning and lubrication. These water outlet holes 1302 are arranged along the tangent direction of the end face and are connected to the water flow channel 21. The water flow is guided to the surface of the CNC tool 1 through the water outlet holes 1302 to ensure that the water flow is evenly distributed and improve the cooling and cleaning effects. The intercepting plate 19 has a plurality of water holes 1901 in the circumferential direction. The flow rate of the water flow is controlled by the water holes 1901 to achieve uniform distribution of the water flow. When the pressing rod 1301 slides, the water retaining ring 20 can block or cancel the blocking of the water holes 1901 on the intercepting plate 19. By sliding the water retaining ring 20, it is possible to control whether the water flow in the water flow channel 21 can flow out through the water holes 1901, thereby controlling the opening or closing of the water flow.

[0039] Furthermore, the first pressure rod 13 also has a spiral channel 18, which is located in the inner wall of the first pressure rod 13 and is connected to the water flow channel 21; it also includes: a rotating paddle 17, which is rotatably arranged in the water flow channel 21; an annular ring 16, which is arranged in the water flow channel 21, and has a water inlet 1602 and a plurality of drain ports 1601, the water inlet 1602 is connected to the spiral channel 18, and the plurality of drain ports 1601 are arranged at intervals on the annular inner wall, and the rotating paddle 17 is located in the annular ring 16.

One end of the sleeve 15 is arranged on the grinding wheel 22, and the other end is arranged on the rotating paddle 17. The rotational power of the rotating paddle 17 is transmitted to the grinding wheel 22 through the sleeve 15, so that the grinding wheel 22 rotates.

The grinding balls 2201 on the grinding wheel 22 can accurately grind the protrusion 103 and the cutting edge 102 of the numerical control tool 1, thereby improving the grinding effect. The rotational power of the water flow is not only used for cooling and cleaning, but also for driving the grinding wheel 22 to rotate, thereby improving the comprehensive utilization rate of the equipment.
