精密零(ling)(ling)件(jian)加工是一種機械(xie)加工，更加精準，是較高的(de)生產(chan)機械(xie)和(he)加工工藝。伴隨著現(xian)代(dai)化(hua)(hua)的(de)發(fa)展，精密機械(xie)加工的(de)類型(xing)越(yue)(yue)來(lai)越(yue)(yue)多，方(fang)位越(yue)(yue)來(lai)越(yue)(yue)細(xi)，越(yue)(yue)來(lai)越(yue)(yue)系(xi)統(tong)化(hua)(hua)。機械(xie)設備由很多不一樣的(de)小(xiao)零(ling)(ling)件(jian)構成，每一個零(ling)(ling)件(jian)都起著重要(yao)的(de)作用。

為了(le)更好(hao)地(di)保證精密(mi)零(ling)(ling)(ling)件(jian)(jian)加(jia)(jia)工(gong)(gong)(gong)精密(mi)度，將(jiang)初加(jia)(jia)工(gong)(gong)(gong)和(he)深(shen)度加(jia)(jia)工(gong)(gong)(gong)的機(ji)(ji)械(xie)零(ling)(ling)(ling)件(jian)(jian)分(fen)(fen)離。因為在加(jia)(jia)工(gong)(gong)(gong)不光滑的機(ji)(ji)械(xie)零(ling)(ling)(ling)件(jian)(jian)時要開展很(hen)多鉆削，產品工(gong)(gong)(gong)件(jian)(jian)承擔很(hen)大的切削速(su)度，夾(jia)持力(li)(li)，熱(re)值多，而且機(ji)(ji)械(xie)零(ling)(ling)(ling)件(jian)(jian)的表層具備顯著的冷作硬化(hua)狀況(kuang)，存(cun)有較(jiao)大的內部地(di)應(ying)力(li)(li)。如何持續加(jia)(jia)工(gong)(gong)(gong)粗機(ji)(ji)械(xie)零(ling)(ling)(ling)件(jian)(jian)和(he)細致機(ji)(ji)械(xie)零(ling)(ling)(ling)件(jian)(jian)，因地(di)應(ying)力(li)(li)的再次遍布(bu)，深(shen)度加(jia)(jia)工(gong)(gong)(gong)后零(ling)(ling)(ling)件(jian)(jian)的精密(mi)度將(jiang)迅速(su)缺失。精密(mi)零(ling)(ling)(ling)件(jian)(jian)加(jia)(jia)工(gong)(gong)(gong)線路中，常分(fen)(fen)配(pei)熱(re)處(chu)理(li)方法。熱(re)處(chu)理(li)工(gong)(gong)(gong)藝全過程的部位分(fen)(fen)配(pei)：為了(le)更好(hao)地(di)提升(sheng)金屬材料的加(jia)(jia)工(gong)(gong)(gong)性，如淬火、熱(re)處(chu)理(li)等一般分(fen)(fen)配(pei)在機(ji)(ji)械(xie)零(ling)(ling)(ling)件(jian)(jian)加(jia)(jia)工(gong)(gong)(gong)前開展。

在(zai)機械制造業的發展中，大家越來越關(guan)心(xin)精(jing)密零(ling)件(jian)加(jia)工(gong)工(gong)藝的品質(zhi)，選用有關(guan)的方式方法開展解決，進一步提高了精(jing)密零(ling)件(jian)加(jia)工(gong)的精(jing)密度。
