  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。加工中心(xin)是高(gao)度機(ji)電一體化的(de)產品(pin)，工件裝(zhuang)夾(jia)(jia)后，數控(kong)系統能控(kong)制機(ji)床按不(bu)同工序(xu)自動(dong)(dong)選擇、更換(huan)刀(dao)(dao)具、自動(dong)(dong)對刀(dao)(dao)、自動(dong)(dong)改(gai)變主軸轉速、進(jin)給量等(deng)，可連續完成鉆(zhan)、鏜、銑、鉸、攻(gong)絲等(deng)多種(zhong)(zhong)工序(xu)，因(yin)而大(da)大(da)減少了工件裝(zhuang)夾(jia)(jia)時間、測量和機(ji)床調整等(deng)輔(fu)助工序(xu)時間，對加工形狀(zhuang)比較復雜，精(jing)度要(yao)求較高(gao)，品(pin)種(zhong)(zhong)更換(huan)頻繁的(de)零(ling)件具有良好的(de)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進一(yi)步(bu)發揮這些優點，數控(kong)機(ji)(ji)床(chuang)遂向(xiang)“工(gong)序(xu)集(ji)中”，即一(yi)臺(tai)數控(kong)機(ji)(ji)床(chuang)在一(yi)次(ci)裝夾零件后能完成多工(gong)序(xu)加工(gong)的數控(kong)機(ji)(ji)床(chuang)(即加工(gong)中心(xin))方面發展(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，首件(批)試切完(wan)后，程序和相關生產(chan)(chan)(chan)(chan)信息可(ke)保留(liu)下(xia)來(lai)，下(xia)次(ci)產(chan)(chan)(chan)(chan)品再生產(chan)(chan)(chan)(chan)時(shi)(shi)，只要很(hen)少的(de)準備時(shi)(shi)間就可(ke)以(yi)開(kai)始生產(chan)(chan)(chan)(chan)。CNC加(jia)工(gong)中心(xin)工(gong)時(shi)(shi)包括準備工(gong)時(shi)(shi)和加(jia)工(gong)工(gong)時(shi)(shi)，CNC加(jia)工(gong)中心(xin)把很(hen)長的(de)單件準備工(gong)時(shi)(shi)平均分配到每一個工(gong)件上，使(shi)每次(ci)生產(chan)(chan)(chan)(chan)的(de)平均實際工(gong)時(shi)(shi)減少，生產(chan)(chan)(chan)(chan)周(zhou)期大大縮短。

        （2）高(gao)精度工(gong)(gong)件(jian)(jian)(jian):有些工(gong)(gong)件(jian)(jian)(jian)需(xu)求甚少(shao)，但屬(shu)關鍵部件(jian)(jian)(jian)，要求精度高(gao)且工(gong)(gong)期(qi)短，用(yong)傳統工(gong)(gong)藝(yi)需(xu)用(yong)多臺(tai)機床協調工(gong)(gong)作，其(qi)周期(qi)長(chang)、效率低(di)，在長(chang)工(gong)(gong)序流程(cheng)中，受人(ren)為(wei)影(ying)響容(rong)易出廢品(pin)，從而(er)造(zao)成重大經濟損失。而(er)采用(yong)CNC加工(gong)(gong)中心進行(xing)加工(gong)(gong),生(sheng)產完全由程(cheng)序自動控(kong)制.避(bi)免了長(chang)工(gong)(gong)序流程(cheng),減(jian)少(shao)了硬(ying)件(jian)(jian)(jian)投資及人(ren)為(wei)干擾(rao)，具有生(sheng)產效益高(gao)及質(zhi)量穩定的特點。

        （3）批(pi)(pi)量生(sheng)(sheng)產(chan)的工(gong)(gong)(gong)(gong)(gong)件(jian)(jian):CNC加(jia)(jia)工(gong)(gong)(gong)(gong)(gong)中(zhong)心生(sheng)(sheng)產(chan)的柔性(xing)不僅體現在(zai)對(dui)特殊要求(qiu)的快速(su)反(fan)應上，而(er)且可(ke)以快速(su)實現批(pi)(pi)量生(sheng)(sheng)產(chan)，以提高市場競爭能力(li)。CNC加(jia)(jia)工(gong)(gong)(gong)(gong)(gong)中(zhong)心適合于中(zhong)小批(pi)(pi)量生(sheng)(sheng)產(chan)，特別是小批(pi)(pi)量生(sheng)(sheng)產(chan)，在(zai)應用(yong)(yong)CNC加(jia)(jia)工(gong)(gong)(gong)(gong)(gong)中(zhong)心時。盡量使(shi)批(pi)(pi)量大于經濟(ji)批(pi)(pi)量,以達到(dao)良好的經濟(ji)效果。隨著CNC加(jia)(jia)工(gong)(gong)(gong)(gong)(gong)中(zhong)心的不斷發(fa)展，經濟(ji)批(pi)(pi)量越來越小，對(dui)一些復雜(za)工(gong)(gong)(gong)(gong)(gong)件(jian)(jian)，5-10件(jian)(jian)就可(ke)以生(sheng)(sheng)產(chan)，甚至單件(jian)(jian)生(sheng)(sheng)產(chan)時也(ye)可(ke)以考慮用(yong)(yong)CNC加(jia)(jia)工(gong)(gong)(gong)(gong)(gong)中(zhong)心。
