A method for manufacturing a knurl wheel as claimed in claim 8, wherein the step of machining a plurality of tapered grooves to form the semi-finished knurl grooves (4) comprises: the round-head milling cutter is fed to the wheel disc body (1) in the radial direction at a low speed, the radial feed speed of the round-head milling cutter is 0.05/s-0.5mm/s, and the processing depth is the target embossing groove (4) depth.
10. The method for manufacturing a knurl wheel as claimed in claim 1, wherein the step of forming the embossing groove (4) in the wheel disc body (1) to obtain the knurl wheel comprises: the milling width is kept consistent towards two end surfaces along the axial direction of the semi-finished product embossing groove (4), the feeding speed along the axial direction is 0.1-1 mm/s, and the single feeding amount along the radial direction is 0.5-0.1 mm.
