CNC精密機械零件加工是(shi)一(yi)種用加(jia)工(gong)(gong)機(ji)(ji)械(xie)(xie)對工(gong)(gong)件(jian)的外形尺寸或性能進行改(gai)變的過(guo)程。CNC精(jing)密(mi)(mi)機(ji)(ji)械(xie)(xie)零件(jian)加(jia)工(gong)(gong)過(guo)程中會有(you)用許(xu)多設備(bei)，一(yi)些常用的機(ji)(ji)械(xie)(xie)設備(bei)有(you)：車(che)床、銑床、磨床、內(nei)/外圓磨、快/慢走絲、火花(hua)機(ji)(ji)、細孔放電機(ji)(ji)、CNC等(deng)精(jing)密(mi)(mi)機(ji)(ji)臺，配有(you)噴砂機(ji)(ji)、滾(gun)磨機(ji)(ji)、清洗機(ji)(ji)等(deng)加(jia)工(gong)(gong)輔助(zhu)設備(bei)。

精密機械零(ling)件(jian)加(jia)工(gong)(gong)(gong)工(gong)(gong)(gong)藝(yi)是規定零(ling)件(jian)精密機械零(ling)件(jian)加(jia)工(gong)(gong)(gong)工(gong)(gong)(gong)藝(yi)過(guo)程和操作方法等(deng)的(de)工(gong)(gong)(gong)藝(yi)，它(ta)是在具(ju)體(ti)的(de)生產(chan)(chan)條件(jian)下，把較為合理(li)的(de)工(gong)(gong)(gong)藝(yi)過(guo)程和操作方法，按照(zhao)規定的(de)形(xing)式(shi)書寫成工(gong)(gong)(gong)藝(yi)文件(jian)，經審批后，用來指導(dao)生產(chan)(chan)。精密機械零(ling)件(jian)加(jia)工(gong)(gong)(gong)工(gong)(gong)(gong)藝(yi)規程一般包括以下內容：工(gong)(gong)(gong)件(jian)加(jia)工(gong)(gong)(gong)的(de)工(gong)(gong)(gong)藝(yi)路線、各工(gong)(gong)(gong)序的(de)具(ju)體(ti)內容及(ji)所(suo)用的(de)設備和工(gong)(gong)(gong)藝(yi)裝(zhuang)備、工(gong)(gong)(gong)件(jian)的(de)檢(jian)驗項(xiang)目及(ji)檢(jian)驗方法、切削用量(liang)、時間定額(e)等(deng)。

CNC精(jing)密(mi)機(ji)(ji)械零件(jian)加工(gong)的優點有很(hen)多(duo)，首先精(jing)密(mi)機(ji)(ji)械零件(jian)加工(gong)能(neng)有效提高勞(lao)動生(sheng)產(chan)率，增加產(chan)量，有較高的經濟效益，減少企業成(cheng)本(ben)。精(jing)密(mi)機(ji)(ji)械零件(jian)加工(gong)還能(neng)改(gai)善(shan)勞(lao)動條件(jian)，降低勞(lao)動強度(du)，縮短勞(lao)動時間，提高文明生(sheng)產(chan)程度(du)。再加上精(jing)密(mi)機(ji)(ji)械零件(jian)加工(gong)能(neng)夠減少生(sheng)產(chan)工(gong)人，廠房面積，縮短生(sheng)產(chan)周期，降低生(sheng)產(chan)成(cheng)本(ben)，節(jie)約(yue)能(neng)源，所以(yi)精(jing)密(mi)機(ji)(ji)械零件(jian)加工(gong)可以(yi)說(shuo)是好處多(duo)多(duo)。
