Do not shovel the condition of technology of figuration milling cutter that grind to be as follows: One, exterior surface roughness 1, before tooth, inside the tooth back face that aperture surface, end panel and shovel wear milling cutter, do not be more than Ra 0.

8 μ M. 2, the milling cutter that shovel tine (do not shovel grind) tooth back face, do not be more than Ra 1.

15 5, material and material of milling cutter of heat treatment figuration use high-speed steel commonly. The hardness after heat treatment should be 63 ～ 66HRC. In the working section of milling cutter, must not have decarburized layer and soft spots. Shovel the figuration milling cutter that grind, its public errand and grade of exterior surface roughness should rise appropriately, can consult from the back example. CNC Milling
