大連模具加工毛坯鍛(duan)造的作用(yong)可使材料組織致密,碳化物分(fen)布(bu)均勻和(he)纖維流(liu)線分(fen)布(bu)合理,從而達(da)到(dao)(dao)改善熱(re)處理性能和(he)提高使用(yong)壽命。在坐標(biao)鏜削加工(gong)(gong)(gong)中,為了保(bao)證孔的位置精度,通常(chang)(chang)要(yao)(yao)進(jin)(jin)行坐標(biao)轉換(huan)(huan)計算.平面孔系(xi)孔距尺寸換(huan)(huan)算三角函數關系(xi)進(jin)(jin)行.空間孔系(xi)加工(gong)(gong)(gong)利用(yong)萬能轉臺(tai)加工(gong)(gong)(gong)軸線與孔系(xi)軸線不平行進(jin)(jin)行鏜削來實現。零件加工(gong)(gong)(gong)通常(chang)(chang)有工(gong)(gong)(gong)藝過程長(chang),工(gong)(gong)(gong)序類別(bie)多和(he)單(dan)件生產(chan)的特點(dian).所以,對(dui)模具零件的 加工(gong)(gong)(gong)中,需(xu)要(yao)(yao)采用(yong)多種加工(gong)(gong)(gong)方(fang)法才(cai)能達(da)到(dao)(dao)所需(xu)要(yao)(yao)求,同時,模具零件的精度和(he)表面粗糙度要(yao)(yao)求都較高,常(chang)(chang)采用(yong)線割(ge)和(he)磨削來保(bao)證。
