  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(xin)是高度機(ji)電一體化的(de)產(chan)品(pin)(pin)，工(gong)(gong)件(jian)裝夾后，數控系統能(neng)控制機(ji)床按(an)不同工(gong)(gong)序自動選(xuan)擇、更換(huan)刀具(ju)、自動對刀、自動改(gai)變主軸轉速、進給量等，可連續(xu)完(wan)成鉆、鏜、銑(xian)、鉸、攻絲等多(duo)種工(gong)(gong)序，因而大大減少了(le)工(gong)(gong)件(jian)裝夾時間(jian)、測量和機(ji)床調(diao)整(zheng)等輔助工(gong)(gong)序時間(jian)，對加(jia)工(gong)(gong)形狀比較復雜，精度要求較高，品(pin)(pin)種更換(huan)頻繁的(de)零件(jian)具(ju)有良(liang)好的(de)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(le)進(jin)一(yi)步發揮這些(xie)優(you)點，數控(kong)機床遂向“工(gong)序集(ji)中”，即(ji)一(yi)臺(tai)數控(kong)機床在一(yi)次裝夾零件后能完成(cheng)多工(gong)序加工(gong)的數控(kong)機床(即(ji)加工(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(pi))試切完后，程序(xu)和(he)相關生(sheng)產信息可保(bao)留(liu)下來(lai)，下次(ci)(ci)產品(pin)再生(sheng)產時(shi)(shi)(shi)，只要很少(shao)的準備(bei)(bei)時(shi)(shi)(shi)間就可以開始生(sheng)產。CNC加工(gong)(gong)(gong)中(zhong)心工(gong)(gong)(gong)時(shi)(shi)(shi)包(bao)括準備(bei)(bei)工(gong)(gong)(gong)時(shi)(shi)(shi)和(he)加工(gong)(gong)(gong)工(gong)(gong)(gong)時(shi)(shi)(shi)，CNC加工(gong)(gong)(gong)中(zhong)心把很長的單件(jian)準備(bei)(bei)工(gong)(gong)(gong)時(shi)(shi)(shi)平(ping)均(jun)分(fen)配到每一個工(gong)(gong)(gong)件(jian)上(shang)，使每次(ci)(ci)生(sheng)產的平(ping)均(jun)實際(ji)工(gong)(gong)(gong)時(shi)(shi)(shi)減少(shao)，生(sheng)產周(zhou)期大大縮短。

        （2）高精度工(gong)(gong)件:有(you)些工(gong)(gong)件需求甚(shen)少，但屬(shu)關(guan)鍵部件，要求精度高且(qie)工(gong)(gong)期短，用(yong)(yong)傳統(tong)工(gong)(gong)藝需用(yong)(yong)多臺機(ji)床協調工(gong)(gong)作，其周期長、效(xiao)率(lv)低(di)，在長工(gong)(gong)序(xu)流(liu)程中(zhong)，受人為影響容(rong)易出廢品，從而造(zao)成重大經濟損失(shi)。而采用(yong)(yong)CNC加工(gong)(gong)中(zhong)心進(jin)行加工(gong)(gong),生產(chan)完全由(you)程序(xu)自(zi)動控制.避(bi)免了長工(gong)(gong)序(xu)流(liu)程,減少了硬件投資及(ji)人為干擾(rao)，具有(you)生產(chan)效(xiao)益高及(ji)質量穩定的特點。

        （3）批量(liang)(liang)生(sheng)(sheng)(sheng)(sheng)產(chan)的工(gong)(gong)(gong)件(jian)(jian):CNC加工(gong)(gong)(gong)中(zhong)(zhong)心(xin)生(sheng)(sheng)(sheng)(sheng)產(chan)的柔(rou)性(xing)不(bu)(bu)僅(jin)體現(xian)在對特殊(shu)要(yao)求的快(kuai)速(su)反應上，而且可以快(kuai)速(su)實現(xian)批量(liang)(liang)生(sheng)(sheng)(sheng)(sheng)產(chan)，以提高市(shi)場競爭能力。CNC加工(gong)(gong)(gong)中(zhong)(zhong)心(xin)適合于(yu)中(zhong)(zhong)小(xiao)批量(liang)(liang)生(sheng)(sheng)(sheng)(sheng)產(chan)，特別是小(xiao)批量(liang)(liang)生(sheng)(sheng)(sheng)(sheng)產(chan)，在應用CNC加工(gong)(gong)(gong)中(zhong)(zhong)心(xin)時。盡量(liang)(liang)使批量(liang)(liang)大于(yu)經(jing)濟批量(liang)(liang),以達到良好的經(jing)濟效果。隨著(zhu)CNC加工(gong)(gong)(gong)中(zhong)(zhong)心(xin)的不(bu)(bu)斷發展(zhan)，經(jing)濟批量(liang)(liang)越來(lai)越小(xiao)，對一些(xie)復雜工(gong)(gong)(gong)件(jian)(jian)，5-10件(jian)(jian)就可以生(sheng)(sheng)(sheng)(sheng)產(chan)，甚至單件(jian)(jian)生(sheng)(sheng)(sheng)(sheng)產(chan)時也可以考慮用CNC加工(gong)(gong)(gong)中(zhong)(zhong)心(xin)。
