[0030] It should be noted that, without conflict, the embodiments in the present application and the features in the embodiments can be combined with each other. The following will refer to the drawings and combine with the embodiments to detail the present application.

[0031] As Figures 1 - 3 shown, the present application relates to an alloy forming tool for machining half holes. The alloy forming tool for machining half holes includes: a tool shank 10; the tool shank 10 refers to the shank part of the tool, which can achieve good clamping and fixing effects, so as to achieve good cooperation effects with other components, and further provide the basis and guarantee for subsequent precise cutting.

[0033] A cutting edge part 30, connected to the connecting part 20 away from one end of the tool shank 10; it can achieve good cutting effects, so as to accurately obtain the required dimensional requirements.

[0034] Wherein, the cutting edge part 30 adopts a two-edge structure with two opposite settings to machine half holes. By adopting the two-edge structure with opposite settings, good half-hole machining effects can be achieved.

[0035] From the above description, it can be seen that the present application has achieved the following technical effects:

Furthermore, it solves the technical problems that in the current half-hole processing, due to the inability of the tool edge band to support, tool deflection during processing, out-of-tolerance cylindricity of the hole, or abnormal wear of the tool edge often occur. Therefore, a milling cutter smaller than the diameter is used for circular interpolation, but the processing time will be greatly extended, and it is often helpless in the processing of the hole opening forming position.

[0040] Furthermore, the edge width of the main cutting edge 301 is 0.05 - 0.15 mm. It can be understood that by setting the edge width of the main cutting edge 301 in the above range, the effect of reducing the burr rate can be achieved.

[0041] Preferably, the edge width of the main cutting edge 301 is 0.1 mm; by controlling the width of the two main cutting edges 301 to be 0.1 mm and verifying the anti-burr of the half hole in the cutting experiment, the burr rate will be reduced by about 30% - 50%.

[0042] Furthermore, a tool chip evacuation groove 40 is provided between the two cutting edge portions 30. It can be understood that good chip evacuation effects can be achieved, thereby not only improving the cutting efficiency and processing accuracy, but also extending the tool service life, reducing manual intervention and processing interruption, and further achieving the purpose of cost saving and production efficiency improvement.
