CNC精密機械零件加工是一(yi)(yi)種用(yong)(yong)加(jia)工(gong)(gong)(gong)機(ji)(ji)械(xie)對工(gong)(gong)(gong)件的外(wai)形尺寸或性能進行改變(bian)的過(guo)程。CNC精(jing)密機(ji)(ji)械(xie)零件加(jia)工(gong)(gong)(gong)過(guo)程中會有(you)用(yong)(yong)許多設備(bei)(bei)(bei)，一(yi)(yi)些常用(yong)(yong)的機(ji)(ji)械(xie)設備(bei)(bei)(bei)有(you)：車床(chuang)(chuang)、銑床(chuang)(chuang)、磨床(chuang)(chuang)、內/外(wai)圓(yuan)磨、快/慢走絲、火花(hua)機(ji)(ji)、細孔放電(dian)機(ji)(ji)、CNC等精(jing)密機(ji)(ji)臺，配有(you)噴(pen)砂機(ji)(ji)、滾(gun)磨機(ji)(ji)、清洗機(ji)(ji)等加(jia)工(gong)(gong)(gong)輔助設備(bei)(bei)(bei)。

精(jing)密(mi)機(ji)械零(ling)件(jian)(jian)(jian)加(jia)(jia)工工藝是規定(ding)零(ling)件(jian)(jian)(jian)精(jing)密(mi)機(ji)械零(ling)件(jian)(jian)(jian)加(jia)(jia)工工藝過程和(he)操作(zuo)方法等的(de)工藝，它(ta)是在具體(ti)的(de)生(sheng)產條件(jian)(jian)(jian)下(xia)(xia)，把較為合理的(de)工藝過程和(he)操作(zuo)方法，按照規定(ding)的(de)形(xing)式書寫成工藝文件(jian)(jian)(jian)，經(jing)審(shen)批后，用來指導生(sheng)產。精(jing)密(mi)機(ji)械零(ling)件(jian)(jian)(jian)加(jia)(jia)工工藝規程一般包括以下(xia)(xia)內容：工件(jian)(jian)(jian)加(jia)(jia)工的(de)工藝路線、各(ge)工序的(de)具體(ti)內容及(ji)所用的(de)設備(bei)和(he)工藝裝備(bei)、工件(jian)(jian)(jian)的(de)檢驗(yan)項目(mu)及(ji)檢驗(yan)方法、切(qie)削用量、時間定(ding)額(e)等。

CNC精密機械(xie)零件加(jia)(jia)(jia)工(gong)(gong)(gong)的(de)優點有很多，首先精密機械(xie)零件加(jia)(jia)(jia)工(gong)(gong)(gong)能(neng)有效提(ti)高勞動生(sheng)產率，增加(jia)(jia)(jia)產量，有較高的(de)經濟效益，減(jian)(jian)少(shao)企業(ye)成本。精密機械(xie)零件加(jia)(jia)(jia)工(gong)(gong)(gong)還能(neng)改(gai)善勞動條件，降(jiang)低勞動強度(du)，縮(suo)短勞動時間，提(ti)高文(wen)明生(sheng)產程度(du)。再加(jia)(jia)(jia)上精密機械(xie)零件加(jia)(jia)(jia)工(gong)(gong)(gong)能(neng)夠減(jian)(jian)少(shao)生(sheng)產工(gong)(gong)(gong)人，廠房面積，縮(suo)短生(sheng)產周期，降(jiang)低生(sheng)產成本，節約能(neng)源(yuan)，所以精密機械(xie)零件加(jia)(jia)(jia)工(gong)(gong)(gong)可(ke)以說是好處多多。
