  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。加工(gong)(gong)(gong)中心(xin)是高度機電(dian)一體化的(de)產品(pin)，工(gong)(gong)(gong)件裝夾后，數控系(xi)統能控制機床按不(bu)同工(gong)(gong)(gong)序自(zi)(zi)動選擇、更換刀具(ju)(ju)、自(zi)(zi)動對刀、自(zi)(zi)動改變主軸轉速、進給量(liang)(liang)等，可連續完(wan)成鉆(zhan)、鏜、銑、鉸、攻絲等多(duo)種工(gong)(gong)(gong)序，因而大大減少(shao)了工(gong)(gong)(gong)件裝夾時間(jian)、測量(liang)(liang)和機床調整等輔助工(gong)(gong)(gong)序時間(jian)，對加工(gong)(gong)(gong)形狀比(bi)較復雜，精度要求較高，品(pin)種更換頻繁(fan)的(de)零件具(ju)(ju)有(you)良好的(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(le)進一(yi)步發(fa)揮這(zhe)些優點(dian)，數控(kong)機(ji)床(chuang)遂向(xiang)“工(gong)序集中(zhong)”，即一(yi)臺數控(kong)機(ji)床(chuang)在一(yi)次(ci)裝夾零件后能完成多工(gong)序加工(gong)的數控(kong)機(ji)床(chuang)(即加工(gong)中(zhong)心)方面發(fa)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，首件(jian)(批)試切完(wan)后，程序和(he)相關生(sheng)產(chan)信息可保(bao)留(liu)下(xia)來(lai)，下(xia)次(ci)產(chan)品再(zai)生(sheng)產(chan)時(shi)(shi)(shi)，只要很少的(de)準(zhun)(zhun)備(bei)時(shi)(shi)(shi)間就可以開始生(sheng)產(chan)。CNC加工(gong)(gong)(gong)(gong)(gong)中心工(gong)(gong)(gong)(gong)(gong)時(shi)(shi)(shi)包括準(zhun)(zhun)備(bei)工(gong)(gong)(gong)(gong)(gong)時(shi)(shi)(shi)和(he)加工(gong)(gong)(gong)(gong)(gong)工(gong)(gong)(gong)(gong)(gong)時(shi)(shi)(shi)，CNC加工(gong)(gong)(gong)(gong)(gong)中心把很長的(de)單件(jian)準(zhun)(zhun)備(bei)工(gong)(gong)(gong)(gong)(gong)時(shi)(shi)(shi)平均(jun)分配到每一個(ge)工(gong)(gong)(gong)(gong)(gong)件(jian)上，使每次(ci)生(sheng)產(chan)的(de)平均(jun)實際工(gong)(gong)(gong)(gong)(gong)時(shi)(shi)(shi)減(jian)少，生(sheng)產(chan)周期大(da)大(da)縮短。

        （2）高(gao)精度工(gong)(gong)(gong)件(jian):有(you)些(xie)工(gong)(gong)(gong)件(jian)需(xu)求甚少，但屬關(guan)鍵部件(jian)，要求精度高(gao)且(qie)工(gong)(gong)(gong)期短，用(yong)(yong)傳(chuan)統工(gong)(gong)(gong)藝需(xu)用(yong)(yong)多臺機床(chuang)協調工(gong)(gong)(gong)作，其(qi)周期長、效率低，在長工(gong)(gong)(gong)序(xu)流(liu)程(cheng)中(zhong)，受人為影響容易出廢(fei)品，從而(er)造成重大(da)經濟損失。而(er)采用(yong)(yong)CNC加工(gong)(gong)(gong)中(zhong)心進行加工(gong)(gong)(gong),生產完全由(you)程(cheng)序(xu)自動控(kong)制(zhi).避免了長工(gong)(gong)(gong)序(xu)流(liu)程(cheng),減少了硬件(jian)投(tou)資及人為干(gan)擾，具有(you)生產效益高(gao)及質量穩(wen)定的特點。

        （3）批量(liang)(liang)(liang)生產(chan)的(de)(de)工(gong)(gong)件(jian)(jian):CNC加(jia)工(gong)(gong)中(zhong)心(xin)生產(chan)的(de)(de)柔(rou)性不(bu)僅體現在對特殊(shu)要求的(de)(de)快速(su)反應(ying)上，而且可以(yi)(yi)快速(su)實現批量(liang)(liang)(liang)生產(chan)，以(yi)(yi)提(ti)高市場競爭能力。CNC加(jia)工(gong)(gong)中(zhong)心(xin)適(shi)合于(yu)中(zhong)小(xiao)(xiao)批量(liang)(liang)(liang)生產(chan)，特別是小(xiao)(xiao)批量(liang)(liang)(liang)生產(chan)，在應(ying)用(yong)CNC加(jia)工(gong)(gong)中(zhong)心(xin)時。盡量(liang)(liang)(liang)使批量(liang)(liang)(liang)大于(yu)經(jing)濟批量(liang)(liang)(liang),以(yi)(yi)達(da)到良好的(de)(de)經(jing)濟效果(guo)。隨(sui)著CNC加(jia)工(gong)(gong)中(zhong)心(xin)的(de)(de)不(bu)斷發展，經(jing)濟批量(liang)(liang)(liang)越來越小(xiao)(xiao)，對一些復(fu)雜工(gong)(gong)件(jian)(jian)，5-10件(jian)(jian)就可以(yi)(yi)生產(chan)，甚(shen)至單件(jian)(jian)生產(chan)時也可以(yi)(yi)考慮用(yong)CNC加(jia)工(gong)(gong)中(zhong)心(xin)。
