大連模具加工毛(mao)坯鍛造的作用(yong)可使(shi)材(cai)料組(zu)織致密,碳化物分布均(jun)勻和(he)纖維(wei)流(liu)線(xian)分布合(he)理(li),從而(er)達到改善熱(re)處(chu)理(li)性能和(he)提(ti)高(gao)使(shi)用(yong)壽(shou)命。在(zai)坐標鏜削加(jia)(jia)工(gong)(gong)中,為了保(bao)證孔(kong)的位置精度(du),通常要(yao)進行(xing)(xing)坐標轉(zhuan)換計算.平面孔(kong)系(xi)孔(kong)距尺寸換算三角函數(shu)關(guan)系(xi)進行(xing)(xing).空間(jian)孔(kong)系(xi)加(jia)(jia)工(gong)(gong)利用(yong)萬能轉(zhuan)臺加(jia)(jia)工(gong)(gong)軸線(xian)與(yu)孔(kong)系(xi)軸線(xian)不平行(xing)(xing)進行(xing)(xing)鏜削來(lai)實現。零件(jian)加(jia)(jia)工(gong)(gong)通常有工(gong)(gong)藝(yi)過程長,工(gong)(gong)序類別多(duo)(duo)和(he)單件(jian)生產(chan)的特(te)點.所(suo)以,對模具零件(jian)的 加(jia)(jia)工(gong)(gong)中,需(xu)要(yao)采(cai)用(yong)多(duo)(duo)種加(jia)(jia)工(gong)(gong)方法才能達到所(suo)需(xu)要(yao)求,同時,模具零件(jian)的精度(du)和(he)表面粗糙度(du)要(yao)求都較高(gao),常采(cai)用(yong)線(xian)割和(he)磨(mo)削來(lai)保(bao)證。
