[0021] In the embodiment, the tool face of front end surface bottom edge 1 opposite to the transition surface of workpiece is provided with plane clearance angle structure, and the plane clearance angle structure includes end tooth first clearance angle 101, end tooth second clearance angle 102, end tooth first R angle clearance angle 103 and end tooth second R angle clearance angle 104; front end surface bottom edge 1 is provided with chip pocket 105 at one end close to outer circumferential edge 2; end tooth first clearance angle 101 and end tooth second clearance angle 102 are respectively located on two opposite edges of front end surface bottom edge 1; end tooth first R angle clearance angle 103 is located in one corner area of front end surface bottom edge 1 and is connected with end tooth first clearance angle 101; end tooth second R angle clearance angle 104 is located in another corner area of front end surface bottom edge 1 and is connected with end tooth second clearance angle 102.
[0022] The surface of the outer circumferential edge 2 is provided with a relief structure, which includes an outer circumferential edge first relief 201 and an outer circumferential edge second relief 202 on the two side surfaces of the outer circumferential edge 2 adjacent to the machined surface of the workpiece;
[0023] Specifically, during machining, the unequal division of the spiral grooves 203 can effectively disperse the cutting force and reduce the vibration between the tool and the workpiece. The relief of the outer circumferential edge 2 adopts a special arc relief form, which, in combination with the unequal division of the spiral grooves 203, further improves the cutting stability of the tool. This design enables the tool to cut into the workpiece more smoothly during machining, reduces the cutting errors caused by vibration, and thus ensures the stability and accuracy of the machining size.
[0024] In embodiment two, the surface of the rear end surface bottom edge 3 opposite to the transition surface of the workpiece is provided with a planar relief structure, which includes a rear end surface bottom edge first relief 301, a rear end surface bottom edge second relief 302, a rear end surface bottom edge first R-angle relief 303, and a rear end surface bottom edge second R-angle relief 304.

[0025] The rear end surface bottom edge first relief 301 is in the form of a finishing edge structure.
[0026] Specifically, the tool is made of super wear-resistant material such as high-performance tungsten steel material, and the surface of the milling tool is also subjected to sandblasting treatment. The tool increases R-angle structure on the surfaces of the front end surface bottom edge 1 and the rear end surface bottom edge 3 opposite to the transition surface of the workpiece, which specifically includes an end tooth first R-angle relief 103, an end tooth second R-angle relief 104, a rear end surface bottom edge first R-angle relief 303, and a rear end surface bottom edge second R-angle relief 304.
[0027] The design of these R-angle structures significantly increases the contact area when the tool tip processes the workpiece, thereby improving the impact resistance of the front and rear end surface tool tips. During cutting, even if hard points or sudden changes in working conditions are encountered, the tool can remain stable and is not prone to jumping or chipping. In addition, the rear end surface bottom edge first relief 301 adopts a finishing edge form structure, which not only improves the wear resistance of the tool in high-efficiency machining scenarios, but also further enhances the overall impact resistance of the tool.
