精密零件加(jia)工是(shi)個復雜(za)而嚴謹(jin)的過程，是(shi)由每個分步的加(jia)工過程組(zu)合而成，那么精密零件加(jia)工的生產具體有哪些要點呢？下面來為大家介(jie)紹下：

機(ji)器的(de)(de)(de)(de)生產(chan)(chan)過(guo)程是指從原材(cai)(cai)料(或(huo)半(ban)成(cheng)(cheng)品(pin))制成(cheng)(cheng)產(chan)(chan)品(pin)的(de)(de)(de)(de)全部過(guo)程。對機(ji)器生產(chan)(chan)而言包(bao)括原材(cai)(cai)料的(de)(de)(de)(de)運輸(shu)和(he)保存，生產(chan)(chan)的(de)(de)(de)(de)準備，毛(mao)坯(pi)的(de)(de)(de)(de)制造(zao)，零件的(de)(de)(de)(de)加工和(he)熱處理，產(chan)(chan)品(pin)的(de)(de)(de)(de)裝配、及(ji)調試，油漆和(he)包(bao)裝等內容。生產(chan)(chan)過(guo)程的(de)(de)(de)(de)內容十分廣泛(fan)，現代(dai)企業用(yong)系統(tong)工程學的(de)(de)(de)(de)原理和(he)方法組織生產(chan)(chan)和(he)指導生產(chan)(chan)，將生產(chan)(chan)過(guo)程看成(cheng)(cheng)是一個具有(you)輸(shu)入和(he)輸(shu)出(chu)的(de)(de)(de)(de)生產(chan)(chan)系統(tong)。

在生(sheng)產過程(cheng)(cheng)中，凡(fan)是改(gai)變(bian)生(sheng)產對象的(de)(de)(de)形狀、尺寸、位(wei)置和性(xing)質等(deng)，使其成為成品或(huo)(huo)者(zhe)半成品的(de)(de)(de)過程(cheng)(cheng)稱(cheng)(cheng)為工(gong)(gong)(gong)藝過程(cheng)(cheng)。它是生(sheng)產過程(cheng)(cheng)的(de)(de)(de)主要(yao)部分。工(gong)(gong)(gong)藝過程(cheng)(cheng)又(you)可分為鑄造、鍛造、沖壓、焊接(jie)、機(ji)械(xie)加工(gong)(gong)(gong)、裝(zhuang)(zhuang)配等(deng)工(gong)(gong)(gong)藝過程(cheng)(cheng)，機(ji)械(xie)制(zhi)造工(gong)(gong)(gong)藝過程(cheng)(cheng)一(yi)般是指零件(jian)的(de)(de)(de)機(ji)械(xie)加工(gong)(gong)(gong)工(gong)(gong)(gong)藝過程(cheng)(cheng)和機(ji)器的(de)(de)(de)裝(zhuang)(zhuang)配工(gong)(gong)(gong)藝過程(cheng)(cheng)的(de)(de)(de)總(zong)和，其他過程(cheng)(cheng)則稱(cheng)(cheng)為輔助過程(cheng)(cheng)，例如運(yun)輸、保管、動力供(gong)應、設備維修等(deng)。工(gong)(gong)(gong)藝過程(cheng)(cheng)又(you)是由(you)一(yi)個(ge)或(huo)(huo)若干(gan)個(ge)順序排列(lie)的(de)(de)(de)工(gong)(gong)(gong)序組成的(de)(de)(de)，一(yi)個(ge)工(gong)(gong)(gong)序由(you)有若干(gan)個(ge)工(gong)(gong)(gong)步(bu)組成。

精密零件(jian)加工(gong)(gong)(gong)(gong)工(gong)(gong)(gong)(gong)藝(yi)過(guo)程(cheng)工(gong)(gong)(gong)(gong)序(xu)(xu)是組成機(ji)械加工(gong)(gong)(gong)(gong)工(gong)(gong)(gong)(gong)藝(yi)過(guo)程(cheng)的(de)基(ji)本單元。所謂(wei)工(gong)(gong)(gong)(gong)序(xu)(xu)是指(zhi)一(yi)(yi)個(或(huo)一(yi)(yi)組)工(gong)(gong)(gong)(gong)人，在一(yi)(yi)臺機(ji)床上(或(huo)一(yi)(yi)個工(gong)(gong)(gong)(gong)作地(di)點)，對同(tong)一(yi)(yi)工(gong)(gong)(gong)(gong)件(jian)(或(huo)同(tong)時對幾個工(gong)(gong)(gong)(gong)件(jian))所連續完成的(de)那一(yi)(yi)部(bu)分(fen)工(gong)(gong)(gong)(gong)藝(yi)過(guo)程(cheng)。構成一(yi)(yi)個工(gong)(gong)(gong)(gong)序(xu)(xu)的(de)主要(yao)特點是不改變加工(gong)(gong)(gong)(gong)對象、設備(bei)和操(cao)作者(zhe)，而且工(gong)(gong)(gong)(gong)序(xu)(xu)的(de)內(nei)容是連續完成的(de)。
