传统铣削加工一般在粗铣时要求铣刀刀齿强度大、容屑槽宽大 ,因此常选择 2齿立铣刀 ;而精铣时每齿负荷小 ,切下切屑少 ,容屑槽可小一些 ,因此一般选择刀齿较密的 4齿或多齿立铣刀。三菱综合材料公司最近推出的粗铣用 4刃整体立铣刀无疑是对传统铣削模式的一个挑战。ＳＺＥ4型立 Conventional milling usually requires milling cutter tooth strength, coarse flute groove, so often choose 2 tooth end mill; and fine milling each tooth load, cut less chips, chip flute may be smaller , So the general choice of more dense teeth 4-tooth or multi-tooth end mill. Mitsubishi General Materials recently introduced roughing and 4-end milling cutter is undoubtedly a challenge to the traditional milling mode. SZE4 type legislation
