Figure 1 As shown, this X-shaped composite bevel not only ensures the welding of the carbon steel layer but also better ensures the welding of the stainless steel layer. The single-sided contour of this X-shaped composite bevel is composed of a first processing surface 100, a second processing surface 200, a third processing surface 300, a fourth processing surface 400, and a fifth processing surface 500 connected sequentially from top to bottom. Currently, the processing methods for this X-shaped composite bevel mainly include the following two methods: one is to use a planer to mechanically process each bevel surface, and after multiple processing steps, the desired stepped X-shaped composite bevel is finally obtained; the other is to use two milling machines, the first machine first mills out the X-shaped bevel shape, and the second machine then mills out the composite layer bevel and the steps, finally obtaining the desired stepped X-shaped composite bevel.

[0034] Optionally, in order to improve the structural strength of the auxiliary block and the tool holder 2, the tool holder 2 and the auxiliary block are integrally formed.

[0035] For details, please refer to Figures 1 to 7The aforementioned plurality of tool holders 2 include a first holder 201, a second holder 202, a third holder 203, and a fourth holder 204 arranged sequentially along the rotation direction of the tool disc body 1.

The tool holder 2 is then fixed by two bolts 5 to restrict the longitudinal movement of the tool holder 2, thereby improving the connection strength between the tool holder 2 and the cutter head body 1 and preventing the tool holder 2 from loosening during processing.

[0038] In some embodiments, please refer to Figures 8 to 10A first through groove 211 is provided on the end face of the first block 21 near the bottom of the first groove 111. In this embodiment, there are four first through grooves 211. During processing, the cutting of the blade will generate a lot of heat. By setting four first through grooves 211, the heat dissipation area of ​​the first block 21 can be increased to facilitate heat dissipation of the blade.

[0039] In some embodiments, a second through groove 212 is provided at the bottom of the first block 21 along its width direction, and the second through groove 212 communicates with the first through groove 211. A third through groove 221 is provided at the bottom of the second block 22 along the connection direction of the first block 21 and the second block 22, and the third through groove 221 communicates with the second through groove 212. Through the above arrangement, the first through groove 211, the second through groove 212 and the third through groove 221 can be connected in sequence to form a heat dissipation channel. In application, while the cutting fluid cools the cutting tool, it can also flow through the above heat dissipation channel through the side wall and bottom surface of the tool holder 2 to absorb the heat transferred by the tool holder 2, further improving the cooling effect of the cutting fluid.

[0040] The above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Any modifications, equivalent substitutions and improvements made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
