  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)(gong)中心(xin)是高(gao)度(du)機電一體化的產品，工(gong)(gong)(gong)(gong)件裝(zhuang)夾后，數控(kong)系統能(neng)控(kong)制(zhi)機床按不同工(gong)(gong)(gong)(gong)序自(zi)動(dong)(dong)選擇(ze)、更換刀(dao)具(ju)、自(zi)動(dong)(dong)對(dui)刀(dao)、自(zi)動(dong)(dong)改變主軸轉速、進給量等，可連續完成鉆、鏜、銑、鉸、攻絲(si)等多種工(gong)(gong)(gong)(gong)序，因而大大減(jian)少(shao)了工(gong)(gong)(gong)(gong)件裝(zhuang)夾時間、測量和機床調整等輔助工(gong)(gong)(gong)(gong)序時間，對(dui)加工(gong)(gong)(gong)(gong)形狀比(bi)較復雜，精度(du)要(yao)求較高(gao)，品種更換頻繁的零件具(ju)有(you)良(liang)好(hao)的經濟效果。

        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)進一步發(fa)揮這(zhe)些(xie)優點，數控(kong)機(ji)床遂向“工序集中(zhong)(zhong)”，即一臺數控(kong)機(ji)床在一次(ci)裝夾零件后(hou)能完成多工序加(jia)工的數控(kong)機(ji)床(即加(jia)工中(zhong)(zhong)心)方(fang)面發(fa)展(zhan)。

        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)(jian)(批)試(shi)切完后，程序和(he)相關生(sheng)產(chan)信息可保(bao)留下來，下次產(chan)品再(zai)生(sheng)產(chan)時(shi)(shi)，只要很少的(de)準備時(shi)(shi)間就可以開始(shi)生(sheng)產(chan)。CNC加工(gong)(gong)中心工(gong)(gong)時(shi)(shi)包(bao)括準備工(gong)(gong)時(shi)(shi)和(he)加工(gong)(gong)工(gong)(gong)時(shi)(shi)，CNC加工(gong)(gong)中心把很長(chang)的(de)單件(jian)(jian)準備工(gong)(gong)時(shi)(shi)平均分配到每(mei)一個工(gong)(gong)件(jian)(jian)上，使每(mei)次生(sheng)產(chan)的(de)平均實際工(gong)(gong)時(shi)(shi)減(jian)少，生(sheng)產(chan)周期(qi)大大縮(suo)短(duan)。

        （2）高精(jing)度工(gong)(gong)(gong)件:有些工(gong)(gong)(gong)件需求(qiu)甚少(shao)，但屬關(guan)鍵部件，要求(qiu)精(jing)度高且工(gong)(gong)(gong)期短，用傳統工(gong)(gong)(gong)藝需用多臺機(ji)床協調工(gong)(gong)(gong)作，其(qi)周期長、效(xiao)率低，在長工(gong)(gong)(gong)序(xu)流程中，受(shou)人(ren)為(wei)影響容易出(chu)廢品(pin)，從而(er)造(zao)成重大(da)經濟損失(shi)。而(er)采用CNC加工(gong)(gong)(gong)中心進行加工(gong)(gong)(gong),生(sheng)產(chan)完全由程序(xu)自(zi)動控制(zhi).避免了長工(gong)(gong)(gong)序(xu)流程,減(jian)少(shao)了硬(ying)件投資及(ji)人(ren)為(wei)干擾(rao)，具有生(sheng)產(chan)效(xiao)益(yi)高及(ji)質量穩定的特點。

        （3）批(pi)量(liang)(liang)(liang)(liang)生產(chan)的(de)工(gong)(gong)件(jian):CNC加(jia)工(gong)(gong)中(zhong)(zhong)(zhong)心(xin)(xin)生產(chan)的(de)柔性(xing)不(bu)(bu)僅體現(xian)在(zai)對特(te)殊要求的(de)快速(su)反應上，而且可(ke)以(yi)快速(su)實現(xian)批(pi)量(liang)(liang)(liang)(liang)生產(chan)，以(yi)提高市(shi)場競爭能力。CNC加(jia)工(gong)(gong)中(zhong)(zhong)(zhong)心(xin)(xin)適合于(yu)中(zhong)(zhong)(zhong)小批(pi)量(liang)(liang)(liang)(liang)生產(chan)，特(te)別是小批(pi)量(liang)(liang)(liang)(liang)生產(chan)，在(zai)應用(yong)CNC加(jia)工(gong)(gong)中(zhong)(zhong)(zhong)心(xin)(xin)時。盡量(liang)(liang)(liang)(liang)使批(pi)量(liang)(liang)(liang)(liang)大于(yu)經濟批(pi)量(liang)(liang)(liang)(liang),以(yi)達(da)到良好的(de)經濟效果。隨(sui)著(zhu)CNC加(jia)工(gong)(gong)中(zhong)(zhong)(zhong)心(xin)(xin)的(de)不(bu)(bu)斷發展(zhan)，經濟批(pi)量(liang)(liang)(liang)(liang)越(yue)來越(yue)小，對一些復雜工(gong)(gong)件(jian)，5-10件(jian)就可(ke)以(yi)生產(chan)，甚至單件(jian)生產(chan)時也(ye)可(ke)以(yi)考慮(lv)用(yong)CNC加(jia)工(gong)(gong)中(zhong)(zhong)(zhong)心(xin)(xin)。
