大連模具加工毛(mao)坯(pi)鍛造的(de)作用(yong)(yong)可使材料(liao)組織致密,碳化物分布均勻(yun)和纖維流(liu)線(xian)(xian)分布合理,從而達到(dao)改善(shan)熱處理性能和提高使用(yong)(yong)壽命。在(zai)坐(zuo)標鏜削(xue)加工(gong)(gong)中,為了保(bao)(bao)證(zheng)孔(kong)的(de)位置精(jing)度(du),通(tong)常(chang)要(yao)進行坐(zuo)標轉(zhuan)換計(ji)算.平(ping)面孔(kong)系(xi)孔(kong)距(ju)尺寸換算三角函數(shu)關系(xi)進行.空間(jian)孔(kong)系(xi)加工(gong)(gong)利用(yong)(yong)萬能轉(zhuan)臺加工(gong)(gong)軸線(xian)(xian)與孔(kong)系(xi)軸線(xian)(xian)不(bu)平(ping)行進行鏜削(xue)來(lai)實現。零件加工(gong)(gong)通(tong)常(chang)有工(gong)(gong)藝過程長(chang),工(gong)(gong)序類別(bie)多和單件生產的(de)特點.所以,對模具零件的(de) 加工(gong)(gong)中,需(xu)要(yao)采用(yong)(yong)多種(zhong)加工(gong)(gong)方法才能達到(dao)所需(xu)要(yao)求(qiu)(qiu),同(tong)時(shi),模具零件的(de)精(jing)度(du)和表面粗(cu)糙度(du)要(yao)求(qiu)(qiu)都較高,常(chang)采用(yong)(yong)線(xian)(xian)割(ge)和磨(mo)削(xue)來(lai)保(bao)(bao)證(zheng)。
