Sharpening of circular arc cutter arc
Our tool workshop mainly produces various types of carbide turning tools. When manufacturing straight shank and crank turning tools, the grinding of the arc part of the insert has been manually ground, which not only has low surface roughness, but also The radius of the arc is also difficult to ensure. To this end, we use the special grinding head of the circular arc head to sharpen the arc of the blade on the tool grinding machine, and achieved good results. The surface roughness of the blade arc is R_α0.8, and the radius is consistent, which meets the drawing requirements. .
