  加工中心簡稱CNC，是由機械設備與數控系統組成的使用于加工復雜形狀工件的高效率自動化機床。加工中心又被稱電腦鑼。加工中心備有刀庫，具有自動換刀功能，是對工件一次裝夾后進行多工序加工的數控機床。加(jia)工(gong)(gong)中心是(shi)高(gao)度機電一體化的(de)(de)產品，工(gong)(gong)件(jian)(jian)裝(zhuang)夾后，數控(kong)系統能(neng)控(kong)制機床按不同(tong)工(gong)(gong)序自(zi)(zi)動(dong)選擇、更(geng)換刀(dao)(dao)具(ju)、自(zi)(zi)動(dong)對(dui)刀(dao)(dao)、自(zi)(zi)動(dong)改變主軸轉速、進給(gei)量(liang)等，可連續完(wan)成鉆、鏜、銑、鉸(jiao)、攻絲等多種工(gong)(gong)序，因而大大減(jian)少(shao)了(le)工(gong)(gong)件(jian)(jian)裝(zhuang)夾時間、測量(liang)和(he)機床調整(zheng)等輔助工(gong)(gong)序時間，對(dui)加(jia)工(gong)(gong)形狀比較(jiao)(jiao)復雜，精度要求較(jiao)(jiao)高(gao)，品種更(geng)換頻繁(fan)的(de)(de)零件(jian)(jian)具(ju)有良好的(de)(de)經濟效果(guo)。

        數控機床實現了中、小批量加工自動化，改善了勞動條件。此外，它還具有生產率高、加工精度穩定、產品成本低等一系列優點。CNC零件加工中心廠家為了進(jin)一(yi)步發揮這些優點，數控(kong)機床(chuang)遂(sui)向“工(gong)序集中(zhong)”，即一(yi)臺數控(kong)機床(chuang)在一(yi)次(ci)裝夾零件后能完(wan)成多(duo)工(gong)序加工(gong)的數控(kong)機床(chuang)(即加工(gong)中(zhong)心)方(fang)面發展。

        CNC立式加工中心的用途:

        （1）期性重復投產的工件:有些產品的市場需求具有周期性和季節性，如果采用專門生產線則得不償失，用普通設備加工效率又太低，且質量不穩定，數量也難以。而采用CNC加工中心，首(shou)件(jian)(批)試(shi)切完后，程序(xu)和(he)相關生產(chan)(chan)信息可(ke)保(bao)留下來，下次產(chan)(chan)品再生產(chan)(chan)時(shi)，只要(yao)很少的(de)準(zhun)備(bei)(bei)時(shi)間就(jiu)可(ke)以開始生產(chan)(chan)。CNC加(jia)(jia)工(gong)(gong)(gong)中(zhong)心工(gong)(gong)(gong)時(shi)包(bao)括準(zhun)備(bei)(bei)工(gong)(gong)(gong)時(shi)和(he)加(jia)(jia)工(gong)(gong)(gong)工(gong)(gong)(gong)時(shi)，CNC加(jia)(jia)工(gong)(gong)(gong)中(zhong)心把很長的(de)單(dan)件(jian)準(zhun)備(bei)(bei)工(gong)(gong)(gong)時(shi)平(ping)均(jun)分配到每(mei)一個(ge)工(gong)(gong)(gong)件(jian)上，使每(mei)次生產(chan)(chan)的(de)平(ping)均(jun)實際工(gong)(gong)(gong)時(shi)減少，生產(chan)(chan)周期(qi)大大縮短。

        （2）高(gao)精(jing)度(du)工(gong)(gong)件(jian):有些(xie)工(gong)(gong)件(jian)需求甚少，但(dan)屬關鍵部件(jian)，要求精(jing)度(du)高(gao)且工(gong)(gong)期短，用傳統(tong)工(gong)(gong)藝需用多(duo)臺機床協調工(gong)(gong)作，其周期長、效率低，在長工(gong)(gong)序(xu)流程中(zhong)，受(shou)人(ren)(ren)為(wei)(wei)影響(xiang)容易出(chu)廢品(pin)，從(cong)而造成重大(da)經濟損(sun)失。而采用CNC加工(gong)(gong)中(zhong)心進行(xing)加工(gong)(gong),生產完(wan)全由程序(xu)自動控制.避免了長工(gong)(gong)序(xu)流程,減少了硬件(jian)投資及人(ren)(ren)為(wei)(wei)干擾，具有生產效益(yi)高(gao)及質量穩定(ding)的特點。

        （3）批(pi)量(liang)生(sheng)產的(de)工(gong)(gong)(gong)件:CNC加(jia)(jia)工(gong)(gong)(gong)中(zhong)心(xin)生(sheng)產的(de)柔性不(bu)(bu)僅體(ti)現在(zai)對特殊要求(qiu)的(de)快(kuai)速反應上，而(er)且可(ke)以(yi)快(kuai)速實(shi)現批(pi)量(liang)生(sheng)產，以(yi)提高市場競爭(zheng)能(neng)力。CNC加(jia)(jia)工(gong)(gong)(gong)中(zhong)心(xin)適合(he)于(yu)中(zhong)小(xiao)批(pi)量(liang)生(sheng)產，特別是小(xiao)批(pi)量(liang)生(sheng)產，在(zai)應用(yong)(yong)CNC加(jia)(jia)工(gong)(gong)(gong)中(zhong)心(xin)時。盡量(liang)使批(pi)量(liang)大于(yu)經濟(ji)(ji)批(pi)量(liang),以(yi)達到良(liang)好的(de)經濟(ji)(ji)效果。隨(sui)著CNC加(jia)(jia)工(gong)(gong)(gong)中(zhong)心(xin)的(de)不(bu)(bu)斷發展，經濟(ji)(ji)批(pi)量(liang)越來越小(xiao)，對一些復雜(za)工(gong)(gong)(gong)件，5-10件就(jiu)可(ke)以(yi)生(sheng)產，甚至(zhi)單件生(sheng)產時也可(ke)以(yi)考慮用(yong)(yong)CNC加(jia)(jia)工(gong)(gong)(gong)中(zhong)心(xin)。
