A symmetric helical tooth milling cutter for processing a narrow long straight sidewall of a thin-walled part, comprising: a cutter head and a shank connected by a keyway; the cutter head comprises: the top of the blade is affixed to each other and symmetrically arranged The upper milling cutter and the lower milling cutter; the upper milling cutter and the lower milling cutter have the same spiral tooth shape. The invention can precisely process thin-walled parts, especially thin-walled parts such as blade leaf crowns, can greatly reduce the axial cutting force during the cutting process, reduce the cutting flutter, improve the cutting surface quality, and the surface texture is uniform and smooth. No sticking, the crown surface is reduced, and the size and precision meet the inspection standards. |
