  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)中(zhong)心是(shi)高度(du)機(ji)電一(yi)體化的產品，工(gong)(gong)件(jian)裝夾后，數(shu)控系統能控制機(ji)床按(an)不同(tong)工(gong)(gong)序(xu)自(zi)動(dong)選擇、更換刀(dao)具(ju)、自(zi)動(dong)對刀(dao)、自(zi)動(dong)改變(bian)主軸(zhou)轉速、進給量等(deng)，可連續完成鉆、鏜、銑、鉸、攻絲等(deng)多種(zhong)工(gong)(gong)序(xu)，因而大大減少了工(gong)(gong)件(jian)裝夾時間(jian)、測量和機(ji)床調整等(deng)輔(fu)助工(gong)(gong)序(xu)時間(jian)，對加工(gong)(gong)形狀(zhuang)比較(jiao)復雜，精(jing)度(du)要求較(jiao)高，品種(zhong)更換頻(pin)繁的零件(jian)具(ju)有(you)良好的經濟效(xiao)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步發揮(hui)這些優點，數控(kong)機床遂向“工(gong)序集中”，即(ji)一臺數控(kong)機床在一次裝夾零件(jian)后能完成多工(gong)序加(jia)工(gong)的數控(kong)機床(即(ji)加(jia)工(gong)中心)方面(mian)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(jian)(批)試(shi)切完后，程序(xu)和相關生(sheng)產(chan)信(xin)息可(ke)保留下來，下次產(chan)品再生(sheng)產(chan)時(shi)，只要很少的準備時(shi)間就(jiu)可(ke)以開(kai)始生(sheng)產(chan)。CNC加工(gong)(gong)(gong)中心(xin)工(gong)(gong)(gong)時(shi)包括(kuo)準備工(gong)(gong)(gong)時(shi)和加工(gong)(gong)(gong)工(gong)(gong)(gong)時(shi)，CNC加工(gong)(gong)(gong)中心(xin)把(ba)很長(chang)的單件(jian)準備工(gong)(gong)(gong)時(shi)平均(jun)分配(pei)到每(mei)一個工(gong)(gong)(gong)件(jian)上，使(shi)每(mei)次生(sheng)產(chan)的平均(jun)實際工(gong)(gong)(gong)時(shi)減(jian)少，生(sheng)產(chan)周期大大縮(suo)短。

        （2）高(gao)精度工(gong)(gong)件(jian):有些工(gong)(gong)件(jian)需求(qiu)甚(shen)少，但(dan)屬關鍵部件(jian)，要求(qiu)精度高(gao)且(qie)工(gong)(gong)期短，用(yong)傳統工(gong)(gong)藝需用(yong)多臺機(ji)床協調工(gong)(gong)作，其周期長(chang)、效(xiao)率(lv)低，在長(chang)工(gong)(gong)序(xu)流(liu)程(cheng)中(zhong)，受人為(wei)影響(xiang)容易出廢品，從而造成(cheng)重大經濟損失(shi)。而采用(yong)CNC加工(gong)(gong)中(zhong)心進行(xing)加工(gong)(gong),生(sheng)產(chan)(chan)完(wan)全由程(cheng)序(xu)自動控制.避(bi)免了長(chang)工(gong)(gong)序(xu)流(liu)程(cheng),減少了硬件(jian)投資及(ji)人為(wei)干擾，具有生(sheng)產(chan)(chan)效(xiao)益高(gao)及(ji)質(zhi)量(liang)穩(wen)定的(de)特點。

        （3）批(pi)(pi)(pi)(pi)量(liang)(liang)生(sheng)(sheng)產(chan)的(de)工(gong)(gong)(gong)件(jian):CNC加(jia)工(gong)(gong)(gong)中心生(sheng)(sheng)產(chan)的(de)柔性不(bu)僅體現(xian)(xian)在對特殊要求的(de)快速反應上，而且可以(yi)(yi)快速實現(xian)(xian)批(pi)(pi)(pi)(pi)量(liang)(liang)生(sheng)(sheng)產(chan)，以(yi)(yi)提高市場競爭能力。CNC加(jia)工(gong)(gong)(gong)中心適合(he)于中小批(pi)(pi)(pi)(pi)量(liang)(liang)生(sheng)(sheng)產(chan)，特別是小批(pi)(pi)(pi)(pi)量(liang)(liang)生(sheng)(sheng)產(chan)，在應用CNC加(jia)工(gong)(gong)(gong)中心時。盡量(liang)(liang)使批(pi)(pi)(pi)(pi)量(liang)(liang)大于經濟批(pi)(pi)(pi)(pi)量(liang)(liang),以(yi)(yi)達到(dao)良好的(de)經濟效果。隨著CNC加(jia)工(gong)(gong)(gong)中心的(de)不(bu)斷發展(zhan)，經濟批(pi)(pi)(pi)(pi)量(liang)(liang)越(yue)來(lai)越(yue)小，對一些復雜工(gong)(gong)(gong)件(jian)，5-10件(jian)就可以(yi)(yi)生(sheng)(sheng)產(chan)，甚至(zhi)單(dan)件(jian)生(sheng)(sheng)產(chan)時也可以(yi)(yi)考慮用CNC加(jia)工(gong)(gong)(gong)中心。
