精密機械零件加工是一種用加工機械對工件的外形尺寸或性能進行改變的過程。一般精密機械加工的(de)定義(yi)是指(zhi)按步驟，按工序完(wan)成各主要表(biao)(biao)面(mian)(mian)的(de)加工，其中包括有工件(jian)平(ping)行度(du)，表(biao)(biao)面(mian)(mian)光(guang)潔度(du)，表(biao)(biao)面(mian)(mian)垂直度(du)，表(biao)(biao)面(mian)(mian)硬度(du)等(deng)等(deng)，可以讓零件(jian)的(de)加工精度(du)以及加工表(biao)(biao)面(mian)(mian)質量達到(dao)圖紙規定的(de)要求。

平(ping)行(xing)度(du)(du)(du)要(yao)求：就(jiu)(jiu)是要(yao)求工件(jian)(jian)周圍(wei)的(de)公差(cha)要(yao)求，比如是矩形(xing)的(de)工件(jian)(jian)，那就(jiu)(jiu)需要(yao)工件(jian)(jian)四(si)個(ge)角(jiao)的(de)厚度(du)(du)(du)要(yao)達(da)到一定(ding)的(de)公差(cha)范圍(wei)內，如果四(si)邊的(de)厚度(du)(du)(du)達(da)不(bu)到公差(cha)的(de)要(yao)求，則達(da)不(bu)到平(ping)行(xing)度(du)(du)(du)的(de)要(yao)求。

垂直度(du)要(yao)求(qiu)(qiu)：就是要(yao)求(qiu)(qiu)工件的側面和地面達(da)到公差要(yao)求(qiu)(qiu)，可以理解成正當體，從數軸來(lai)看(kan)，分為XYZ三面，一(yi)般要(yao)求(qiu)(qiu)XZ，YZ達(da)到公差要(yao)求(qiu)(qiu)，出現誤差也和平(ping)行(xing)度(du)要(yao)求(qiu)(qiu)的大致(zhi)，一(yi)般按(an)照平(ping)行(xing)度(du)要(yao)求(qiu)(qiu)來(lai)處理則可。

同時我們(men)精密機械零件加(jia)(jia)(jia)工(gong)(gong)(gong)(gong)(gong)按照它所處(chu)的(de)的(de)溫度狀態(tai)﹐分為(wei)冷(leng)加(jia)(jia)(jia)工(gong)(gong)(gong)(gong)(gong)和(he)熱加(jia)(jia)(jia)工(gong)(gong)(gong)(gong)(gong)。一(yi)般在(zai)常溫下(xia)加(jia)(jia)(jia)工(gong)(gong)(gong)(gong)(gong),并且不(bu)引起(qi)工(gong)(gong)(gong)(gong)(gong)件的(de)化學或(huo)物(wu)相變化﹐稱冷(leng)加(jia)(jia)(jia)工(gong)(gong)(gong)(gong)(gong)。一(yi)般在(zai)高于或(huo)低于常溫狀態(tai)的(de)加(jia)(jia)(jia)工(gong)(gong)(gong)(gong)(gong)﹐會(hui)引起(qi)工(gong)(gong)(gong)(gong)(gong)件的(de)化學或(huo)物(wu)相變化﹐稱熱加(jia)(jia)(jia)工(gong)(gong)(gong)(gong)(gong)。冷(leng)加(jia)(jia)(jia)工(gong)(gong)(gong)(gong)(gong)按加(jia)(jia)(jia)工(gong)(gong)(gong)(gong)(gong)方(fang)式的(de)差別可(ke)分為(wei)切削(xue)加(jia)(jia)(jia)工(gong)(gong)(gong)(gong)(gong)和(he)壓(ya)力加(jia)(jia)(jia)工(gong)(gong)(gong)(gong)(gong)。熱加(jia)(jia)(jia)工(gong)(gong)(gong)(gong)(gong)常見(jian)有熱處(chu)理﹐鍛造﹐鑄造和(he)焊接。
