CNC精密機械零件加工是一(yi)種用加工(gong)機(ji)(ji)(ji)(ji)械(xie)(xie)(xie)對工(gong)件(jian)的外(wai)形尺寸或性(xing)能進(jin)行改變(bian)的過(guo)程。CNC精(jing)密機(ji)(ji)(ji)(ji)械(xie)(xie)(xie)零件(jian)加工(gong)過(guo)程中會有(you)用許多(duo)設備，一(yi)些常用的機(ji)(ji)(ji)(ji)械(xie)(xie)(xie)設備有(you)：車(che)床(chuang)、銑(xian)床(chuang)、磨(mo)床(chuang)、內/外(wai)圓磨(mo)、快/慢(man)走絲、火(huo)花機(ji)(ji)(ji)(ji)、細孔(kong)放電機(ji)(ji)(ji)(ji)、CNC等精(jing)密機(ji)(ji)(ji)(ji)臺，配有(you)噴(pen)砂(sha)機(ji)(ji)(ji)(ji)、滾磨(mo)機(ji)(ji)(ji)(ji)、清洗機(ji)(ji)(ji)(ji)等加工(gong)輔助設備。

精(jing)密(mi)機械(xie)零件(jian)加工(gong)(gong)(gong)(gong)(gong)工(gong)(gong)(gong)(gong)(gong)藝(yi)(yi)是規定零件(jian)精(jing)密(mi)機械(xie)零件(jian)加工(gong)(gong)(gong)(gong)(gong)工(gong)(gong)(gong)(gong)(gong)藝(yi)(yi)過程(cheng)和操(cao)(cao)作(zuo)(zuo)方法(fa)等的(de)(de)(de)(de)工(gong)(gong)(gong)(gong)(gong)藝(yi)(yi)，它是在具(ju)體的(de)(de)(de)(de)生產條(tiao)件(jian)下，把較(jiao)為合(he)理(li)的(de)(de)(de)(de)工(gong)(gong)(gong)(gong)(gong)藝(yi)(yi)過程(cheng)和操(cao)(cao)作(zuo)(zuo)方法(fa)，按照(zhao)規定的(de)(de)(de)(de)形式書寫成工(gong)(gong)(gong)(gong)(gong)藝(yi)(yi)文件(jian)，經審批后，用(yong)來指導生產。精(jing)密(mi)機械(xie)零件(jian)加工(gong)(gong)(gong)(gong)(gong)工(gong)(gong)(gong)(gong)(gong)藝(yi)(yi)規程(cheng)一般包括(kuo)以(yi)下內容：工(gong)(gong)(gong)(gong)(gong)件(jian)加工(gong)(gong)(gong)(gong)(gong)的(de)(de)(de)(de)工(gong)(gong)(gong)(gong)(gong)藝(yi)(yi)路線、各工(gong)(gong)(gong)(gong)(gong)序的(de)(de)(de)(de)具(ju)體內容及(ji)所(suo)用(yong)的(de)(de)(de)(de)設備(bei)和工(gong)(gong)(gong)(gong)(gong)藝(yi)(yi)裝(zhuang)備(bei)、工(gong)(gong)(gong)(gong)(gong)件(jian)的(de)(de)(de)(de)檢驗項目及(ji)檢驗方法(fa)、切削用(yong)量(liang)、時間(jian)定額等。

CNC精(jing)(jing)(jing)密(mi)機械零(ling)(ling)件(jian)加(jia)工(gong)的(de)優點(dian)有很多，首先精(jing)(jing)(jing)密(mi)機械零(ling)(ling)件(jian)加(jia)工(gong)能有效(xiao)提高(gao)勞(lao)(lao)動生(sheng)(sheng)產(chan)率，增(zeng)加(jia)產(chan)量，有較高(gao)的(de)經濟效(xiao)益，減(jian)少企(qi)業成本。精(jing)(jing)(jing)密(mi)機械零(ling)(ling)件(jian)加(jia)工(gong)還(huan)能改(gai)善勞(lao)(lao)動條件(jian)，降低勞(lao)(lao)動強度，縮短勞(lao)(lao)動時間，提高(gao)文明生(sheng)(sheng)產(chan)程度。再加(jia)上精(jing)(jing)(jing)密(mi)機械零(ling)(ling)件(jian)加(jia)工(gong)能夠減(jian)少生(sheng)(sheng)產(chan)工(gong)人，廠房(fang)面積，縮短生(sheng)(sheng)產(chan)周期，降低生(sheng)(sheng)產(chan)成本，節約能源，所以精(jing)(jing)(jing)密(mi)機械零(ling)(ling)件(jian)加(jia)工(gong)可(ke)以說是(shi)好(hao)處多多。
