精密(mi)零(ling)(ling)(ling)件加工(gong)(gong)是一種機(ji)械(xie)(xie)加工(gong)(gong)，更加精準，是較高的(de)生產機(ji)械(xie)(xie)和加工(gong)(gong)工(gong)(gong)藝。伴隨著(zhu)(zhu)現代化的(de)發展，精密(mi)機(ji)械(xie)(xie)加工(gong)(gong)的(de)類型越來越多，方位越來越細，越來越系統(tong)化。機(ji)械(xie)(xie)設備由(you)很多不一樣的(de)小零(ling)(ling)(ling)件構成，每(mei)一個零(ling)(ling)(ling)件都起著(zhu)(zhu)重(zhong)要的(de)作用。

為(wei)了更好(hao)地保證精密(mi)零(ling)(ling)(ling)件(jian)(jian)(jian)(jian)(jian)加(jia)工(gong)精密(mi)度(du)(du)，將(jiang)初(chu)加(jia)工(gong)和深度(du)(du)加(jia)工(gong)的(de)(de)(de)(de)機(ji)械(xie)零(ling)(ling)(ling)件(jian)(jian)(jian)(jian)(jian)分離。因(yin)為(wei)在(zai)加(jia)工(gong)不(bu)光滑(hua)的(de)(de)(de)(de)機(ji)械(xie)零(ling)(ling)(ling)件(jian)(jian)(jian)(jian)(jian)時要開展很多(duo)鉆(zhan)削，產品工(gong)件(jian)(jian)(jian)(jian)(jian)承擔(dan)很大(da)的(de)(de)(de)(de)切削速度(du)(du)，夾持力(li)，熱(re)(re)值多(duo)，而且機(ji)械(xie)零(ling)(ling)(ling)件(jian)(jian)(jian)(jian)(jian)的(de)(de)(de)(de)表層具備顯著的(de)(de)(de)(de)冷(leng)作(zuo)硬化狀(zhuang)況，存有較大(da)的(de)(de)(de)(de)內部地應力(li)。如(ru)何持續(xu)加(jia)工(gong)粗機(ji)械(xie)零(ling)(ling)(ling)件(jian)(jian)(jian)(jian)(jian)和細致(zhi)機(ji)械(xie)零(ling)(ling)(ling)件(jian)(jian)(jian)(jian)(jian)，因(yin)地應力(li)的(de)(de)(de)(de)再次遍(bian)布，深度(du)(du)加(jia)工(gong)后(hou)零(ling)(ling)(ling)件(jian)(jian)(jian)(jian)(jian)的(de)(de)(de)(de)精密(mi)度(du)(du)將(jiang)迅速缺(que)失。精密(mi)零(ling)(ling)(ling)件(jian)(jian)(jian)(jian)(jian)加(jia)工(gong)線(xian)路中，常分配(pei)熱(re)(re)處(chu)理方(fang)法。熱(re)(re)處(chu)理工(gong)藝全過程的(de)(de)(de)(de)部位分配(pei)：為(wei)了更好(hao)地提升金屬材料的(de)(de)(de)(de)加(jia)工(gong)性(xing)，如(ru)淬(cui)火(huo)、熱(re)(re)處(chu)理等一般(ban)分配(pei)在(zai)機(ji)械(xie)零(ling)(ling)(ling)件(jian)(jian)(jian)(jian)(jian)加(jia)工(gong)前開展。

在機械制(zhi)造業的(de)發展中，大家越來越關心精密零(ling)件(jian)加工工藝的(de)品質，選(xuan)用有關的(de)方(fang)(fang)式(shi)方(fang)(fang)法開展解決，進一步提高了(le)精密零(ling)件(jian)加工的(de)精密度。
