Description

Technical Field

[0001] The utility model relates to the technical field of numerical control machine tools, in particular to a machining tool for a numerical control machine tool. Background Art

[0002] CNC nanomachining is a method of nanoscale processing using computer numerical control (CNC) technology. This processing technology combines sophisticated mechanical systems, advanced measurement technology and high-precision control algorithms to accurately manufacture and process parts or structures at the nanoscale.

[0003] Although the processing accuracy of CNC machine tools is already quite high, there is still a common and thorny problem when processing aluminum products. The shape angle design of existing CNC machine tool tools may not fully adapt to the processing characteristics of workpieces such as aluminum products. For example, the selection of rake angle, back angle and deflection angle may not effectively disperse the cutting force, thereby increasing the possibility of burrs. Utility Model Content

[0004] The utility model aims to overcome the deficiencies of the prior art and provide a CNC machine tool processing tool to solve the technical problem that the workpiece has more burrs after the prior tool is processed.

[0005] In order to solve the above technical problems, the utility model adopts the following technical solutions:

[0006] A CNC machine tool machining tool comprises a tool body, wherein the tool body comprises: a tool handle and a cutting edge arranged at one end of the tool handle, wherein the cutting edge comprises a first transition section, a first cutting section, a second transition section, a second cutting section and a third cutting section which are sequentially connected and arranged, wherein the longitudinal section of the first transition section is an isosceles trapezoid whose width gradually decreases in a direction away from the tool handle, the longitudinal section of the first cutting section is an isosceles trapezoid whose width gradually decreases in a direction away from the tool handle, and the inclination angle of the first cutting section is greater than the inclination angle of the first transition section; the longitudinal section of the second transition section is a rectangle; the longitudinal section of the second cutting section is an isosceles trapezoid whose width gradually increases in a direction away from the tool handle; and the longitudinal section of the third cutting section is a rectangle.

[0007] Preferably, the length L2 of the second cutting segment is 10.26 mm±0.01, and the angle α between two side edges of the longitudinal section of the second cutting segment is 29.6°.

[0008] Preferably, the angle β between the two side edges of the longitudinal section of the first cutting segment is 165.0°.

[0009] Preferably, the longitudinal section length L3 of the third cutting segment is 0.54 mm±0.01, and the longitudinal section width D2 of the third cutting segment is 10.85 mm±0.01.

[0010] Preferably, the width D3 of the longitudinal section of the second transition section is 5.42 mm±0.01.

[0011] Preferably, the length L1 of the blade body is 103.05 mm±0.01.

[0012] Preferably, the width D1 of the handle is 10.26 mm±0.01.

[0013] The beneficial effects of the utility model are as follows: the first transition section and the first cutting section adopt an isosceles trapezoidal design with a gradually decreasing width. This structure enables the tool to gradually cut in with a gentler slope when contacting the workpiece material, thereby reducing the material tearing or fiber breakage caused by sudden impact, thereby reducing the generation of burrs. The inclination angle of the first cutting section is greater than that of the first transition section, which helps to improve the cutting efficiency and ensure the stability of the initial cutting stage. The larger cutting angle can provide a better chip splitting effect, making it easier to discharge the chips generated by cutting, and reducing the burrs formed by the extrusion of the chips. The second transition section is a rectangular cross-section, and its straight design ensures the stability during the cutting process, avoids the edge burr problem caused by excessive deformation, and is also conducive to the smooth transition between different cutting sections. The longitudinal section of the second cutting section is an isosceles trapezoidal shape with a width gradually increasing in the direction away from the handle. Such a design helps to trim and smooth the machined surface in the further cutting process, and can effectively reduce the burr phenomenon of the edge residue. The third cutting section also adopts a rectangular cross-section, which can provide accurate and stable cutting conditions in the final stage, and has a significant effect on eliminating the possible residual micro burrs and improving the surface quality of the workpiece. The CNC machine tool processing tool has achieved effective control from cutting in, main cutting to finishing through fine geometric shape design, which not only improves the cutting performance and efficiency, but also significantly reduces the burr generation after workpiece processing, thereby improving product quality and production efficiency.

[0026] In this embodiment, the first transition section 25 and the first cutting section 21 are designed with an isosceles trapezoid with a gradually decreasing width. This structure allows the tool to gradually cut in with a gentler slope when contacting the workpiece 200 material, thereby reducing material tearing or fiber breakage caused by sudden impact, thereby reducing the generation of burrs. The inclination angle of the first cutting section 21 is greater than that of the first transition section 25, which helps to improve cutting efficiency and ensures the stability of the initial cutting stage. A larger cutting angle can provide a better chip separation effect, making it easier to discharge the chips generated by cutting and reducing burrs formed by chip extrusion.

Such a design helps to trim and smooth the processed surface during further cutting, and can effectively reduce the burr phenomenon remaining on the edge. The third cutting section 24 also adopts a rectangular cross section, which can provide accurate and stable cutting conditions in the final stage, and has a significant effect on eliminating possible residual micro burrs and improving the surface quality of the workpiece 200. The CNC machine tool processing tool realizes effective control from cutting, main cutting to finishing through fine geometric shape design, which not only improves cutting performance and efficiency, but also significantly reduces the generation of burrs after the workpiece 200 is processed, thereby improving product quality and production efficiency.

[0027] In this embodiment, the included angle β of both sides of the longitudinal section of the first cutting segment 21 is 165.0°.

[0028] In this embodiment, the longitudinal section length L3 of the third cutting segment 24 is 0.54 mm±0.01, and the longitudinal section width D2 of the third cutting segment 24 is 10.85 mm±0.01.

[0029] In this embodiment, the width D3 of the longitudinal section of the second transition section 22 is 5.42 mm±0.01.

[0030] In this embodiment, the length L1 of the blade body 100 is 103.05 mm±0.01.

[0032] In summary, compared with the existing technology, the CNC machine tool processing tool has at least the following beneficial effects: through the fine geometric shape design, the CNC machine tool processing tool realizes effective control of each stage from cutting in, main cutting to finishing, which not only improves the cutting performance and efficiency, but also significantly reduces the burr generation of the workpiece 200 after processing, thereby improving product quality and production efficiency.

To make the description concise, not all possible combinations of the technical features in the above-described embodiments are described. However, as long as there is no contradiction in the combination of these technical features, they should be considered to be within the scope of this specification.

[0034] The above-mentioned embodiments only express several implementation methods of the utility model, and the description is relatively specific and detailed, but it cannot be understood as limiting the scope of the utility model patent. It should be pointed out that for ordinary technicians in this field, several modifications and improvements can be made without departing from the concept of the utility model, which all belong to the protection scope of the utility model.
