Milling

Regard the cutting of cutting tool as treatment with gyral milling cutter. Milling undertakes on milling machine or boring machine commonly, comfortable at machining all sorts of planar, groove, figuration faces (be like spline, gear and whorl) the special entity face with the mould. The feature of milling is: Each tooth participates in ① milling cutter periodicly discontinuous cutting; Every tooth is in ② the cutting ply in cutting process is change. Graph 1 it is a few kinds of familiar milling treatment pattern.

Graph the tooth back appearance of milling cutter of 6 pointed tine

Milling cutter presses the treatment means cent of tooth back to be two kinds. Milling cutter of ① needle tine: Go up at the back grind give a narrow first flank in order to form hind horn, because cutting angle is reasonable, its life is taller. The tooth back of pointed tine milling cutter has linear curve and broken line 3 kinds of forms (graph 6) . Linear tooth back is commonly used the finish machining milling cutter at serration. The tooth strength of curve and broken line tooth back is better, can bear heavier cutting load, commonly used at thick tine milling cutter. ② shovels tine milling cutter: Cut with the shovel at the back of its (or the shovel is ground) the tooth back that the method processes corkscrewed yarn of Cheng Aji Meade, milling cutter is used blunt hind simply is ground again in front, can carry original tooth form changeless, use at making all sorts of figuration milling cutter such as gear milling cutter.
