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 nanometer level.

[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 two cutting edges arranged at one end of the tool handle and arranged opposite to each other, the cutting edges comprising a first cutting segment, a second cutting segment and a third cutting segment which are arranged in sequence, the first cutting segment being arranged obliquely to the length direction of the tool handle, the two first cutting segments being arranged close to each other in a direction away from the tool handle, the second cutting segment being arranged in an outwardly protruding arc shape, and the third cutting segment being arranged parallel to the tool handle.

[0007] Furthermore, the tolerance of the angle α between the two first cutting segments is 37°±0.0.

[0008] Furthermore, the tolerance of the arc radius R1 of the second cutting segment is 36 mm±0.01.

[0009] Furthermore, an arc transition is arranged between the first cutting segment and the second cutting segment, and the tolerance of the arc radius R2 is 15 mm±0.01.

[0010] Furthermore, the tolerance of the length L1 of the blade body is 38.00 mm±0.01.

[0011] Furthermore, the tolerance of the length L2 of the second cutting segment and the third cutting segment is 1.60 mm±0.01.

[0012] Furthermore, the width D1 of the blade body has a tolerance of 4.00 mm±0.01.

[0013] Furthermore, the tolerance of the width D2 of the cutting edge away from one end of the blade body is 4.00 mm±0.01.

[0014] Beneficial effects of the utility model: The unique design of the tool body, including a tool handle and two opposing cutting edges arranged at one end of the tool handle, enables the tool to more accurately control the cutting force and direction when performing cutting operations, thereby reducing unnecessary workpiece tearing and burr generation. The segmented structural design of the cutting edge, including a first cutting segment, a second cutting segment and a third cutting segment, helps to gradually and smoothly remove the workpiece material and avoid the generation of burrs caused by sudden force changes. The first cutting segment is arranged obliquely to the length direction of the tool handle, and the two first cutting segments approach each other in the direction away from the tool handle. This design is conducive to dispersing stress during initial cutting and reducing the possibility of burr formation. The second cutting segment is arranged in an outwardly protruding arc shape. This feature enables the tool to transition more smoothly during the cutting process, avoiding stress concentration and burr problems caused by right angles or sharp angles. The arc-shaped design helps to evenly distribute the cutting force and further reduce the generation of burrs. BRIEF DESCRIPTION OF THE DRAWINGS
