精密零件加工(gong)是(shi)一(yi)種機(ji)械(xie)加工(gong)，更加精準(zhun)，是(shi)較(jiao)高的(de)(de)生產(chan)機(ji)械(xie)和加工(gong)工(gong)藝。伴隨(sui)著(zhu)現代化(hua)(hua)的(de)(de)發展，精密機(ji)械(xie)加工(gong)的(de)(de)類型越(yue)來越(yue)多(duo)，方位越(yue)來越(yue)細(xi)，越(yue)來越(yue)系統化(hua)(hua)。機(ji)械(xie)設備由很多(duo)不一(yi)樣的(de)(de)小零件構(gou)成，每一(yi)個零件都起(qi)著(zhu)重要的(de)(de)作用。

為了更(geng)好地保證精(jing)密零(ling)(ling)件(jian)(jian)加(jia)(jia)(jia)工(gong)(gong)(gong)精(jing)密度(du)，將初加(jia)(jia)(jia)工(gong)(gong)(gong)和深度(du)加(jia)(jia)(jia)工(gong)(gong)(gong)的機械(xie)(xie)零(ling)(ling)件(jian)(jian)分(fen)離(li)。因為在(zai)加(jia)(jia)(jia)工(gong)(gong)(gong)不光滑的機械(xie)(xie)零(ling)(ling)件(jian)(jian)時要開展(zhan)很多鉆削，產品工(gong)(gong)(gong)件(jian)(jian)承擔(dan)很大(da)(da)的切(qie)削速(su)度(du)，夾持力，熱值多，而且機械(xie)(xie)零(ling)(ling)件(jian)(jian)的表(biao)層(ceng)具備顯著的冷(leng)作硬化狀況，存有較大(da)(da)的內部地應力。如何持續加(jia)(jia)(jia)工(gong)(gong)(gong)粗機械(xie)(xie)零(ling)(ling)件(jian)(jian)和細(xi)致機械(xie)(xie)零(ling)(ling)件(jian)(jian)，因地應力的再次遍布，深度(du)加(jia)(jia)(jia)工(gong)(gong)(gong)后零(ling)(ling)件(jian)(jian)的精(jing)密度(du)將迅(xun)速(su)缺失。精(jing)密零(ling)(ling)件(jian)(jian)加(jia)(jia)(jia)工(gong)(gong)(gong)線(xian)路(lu)中，常(chang)分(fen)配(pei)熱處(chu)理方法。熱處(chu)理工(gong)(gong)(gong)藝全過程(cheng)的部位分(fen)配(pei)：為了更(geng)好地提升(sheng)金屬材料的加(jia)(jia)(jia)工(gong)(gong)(gong)性，如淬火(huo)、熱處(chu)理等一般分(fen)配(pei)在(zai)機械(xie)(xie)零(ling)(ling)件(jian)(jian)加(jia)(jia)(jia)工(gong)(gong)(gong)前開展(zhan)。

在機械制造業(ye)的(de)發展中，大家越來(lai)越關(guan)心精密(mi)零(ling)件(jian)加(jia)工(gong)工(gong)藝的(de)品質，選用有關(guan)的(de)方(fang)式(shi)方(fang)法開展解決，進一步(bu)提高(gao)了精密(mi)零(ling)件(jian)加(jia)工(gong)的(de)精密(mi)度(du)。
