大連模具加工毛坯鍛造的(de)作用可(ke)使材料組織致密,碳(tan)化物(wu)分布均勻(yun)和(he)(he)纖維流(liu)線分布合理(li),從而達(da)到改善熱處理(li)性能和(he)(he)提高(gao)使用壽命。在坐標鏜削(xue)加工(gong)(gong)(gong)中(zhong),為了保(bao)證孔(kong)的(de)位(wei)置精度,通(tong)常要(yao)進(jin)行(xing)坐標轉換計算(suan).平面(mian)孔(kong)系孔(kong)距尺寸換算(suan)三角(jiao)函數關系進(jin)行(xing).空間孔(kong)系加工(gong)(gong)(gong)利用萬能轉臺加工(gong)(gong)(gong)軸線與孔(kong)系軸線不平行(xing)進(jin)行(xing)鏜削(xue)來(lai)實現。零件加工(gong)(gong)(gong)通(tong)常有工(gong)(gong)(gong)藝過(guo)程(cheng)長(chang),工(gong)(gong)(gong)序類別多和(he)(he)單件生產的(de)特點.所以(yi),對模具(ju)零件的(de) 加工(gong)(gong)(gong)中(zhong),需要(yao)采用多種加工(gong)(gong)(gong)方法才能達(da)到所需要(yao)求,同(tong)時,模具(ju)零件的(de)精度和(he)(he)表(biao)面(mian)粗(cu)糙度要(yao)求都(dou)較高(gao),常采用線割和(he)(he)磨削(xue)來(lai)保(bao)證。
