[0028] The installation inclination angle of the A teeth 2 is 5° in the positive direction, and the installation inclination angle a of the B teeth 3 is 5° in the negative direction.

[0029] As shown in Figure 2The figure shows a schematic diagram of the AB tooth combination. In the present invention, the A tooth and the B tooth are installed in reverse. Since the tool is side milling, the overlapping width of the side milling edge width D1 of the A tooth and the side milling edge width D2 of the B tooth is P. The total edge width after overlap is D1+D2-P=L, where L is the width of the T-slot to be processed.

[0030] The side milling edge width D1 of tooth A and the side milling edge width D2 of tooth B may be the same or different.

[0031] like Figure 3 As shown, the end face angles of the cutter head 1 are not equally divided. In this embodiment, the number of A teeth 2 and B teeth 3 are both 2, and the end face angles are 93°, 87°, 93°, and 87° respectively.
