  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)中心是高(gao)度(du)機(ji)(ji)電一體化(hua)的產品(pin)，工(gong)(gong)(gong)件(jian)(jian)裝(zhuang)夾(jia)后，數(shu)控系統能控制(zhi)機(ji)(ji)床按(an)不同工(gong)(gong)(gong)序自(zi)動(dong)(dong)選擇、更(geng)換(huan)刀具、自(zi)動(dong)(dong)對刀、自(zi)動(dong)(dong)改變(bian)主軸(zhou)轉速、進給量等(deng)，可連(lian)續完成鉆、鏜、銑(xian)、鉸、攻絲(si)等(deng)多種工(gong)(gong)(gong)序，因(yin)而大(da)大(da)減少了工(gong)(gong)(gong)件(jian)(jian)裝(zhuang)夾(jia)時間、測量和機(ji)(ji)床調整等(deng)輔助工(gong)(gong)(gong)序時間，對加工(gong)(gong)(gong)形狀(zhuang)比較(jiao)復(fu)雜，精(jing)度(du)要求(qiu)較(jiao)高(gao)，品(pin)種更(geng)換(huan)頻(pin)繁的零件(jian)(jian)具有(you)良好的經濟效果。

        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)進一步發揮這(zhe)些優點，數控機(ji)床(chuang)遂向“工序集中(zhong)(zhong)”，即一臺(tai)數控機(ji)床(chuang)在一次裝夾零件后能(neng)完(wan)成多工序加工的數控機(ji)床(chuang)(即加工中(zhong)(zhong)心)方面發展。

        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(批)試切完(wan)后，程(cheng)序和(he)相關生(sheng)產(chan)信息可保留下來，下次產(chan)品再生(sheng)產(chan)時，只要很少的準(zhun)備(bei)時間就可以開始生(sheng)產(chan)。CNC加(jia)工(gong)(gong)中心工(gong)(gong)時包(bao)括準(zhun)備(bei)工(gong)(gong)時和(he)加(jia)工(gong)(gong)工(gong)(gong)時，CNC加(jia)工(gong)(gong)中心把(ba)很長的單件準(zhun)備(bei)工(gong)(gong)時平(ping)均(jun)分配(pei)到每(mei)一個工(gong)(gong)件上(shang)，使(shi)每(mei)次生(sheng)產(chan)的平(ping)均(jun)實際工(gong)(gong)時減少，生(sheng)產(chan)周(zhou)期大大縮短(duan)。

        （2）高精(jing)度工(gong)(gong)件(jian):有些工(gong)(gong)件(jian)需(xu)(xu)求甚(shen)少，但屬關鍵部件(jian)，要求精(jing)度高且(qie)工(gong)(gong)期短(duan)，用(yong)傳統工(gong)(gong)藝需(xu)(xu)用(yong)多臺機床協調工(gong)(gong)作，其周期長、效率(lv)低(di)，在長工(gong)(gong)序流程(cheng)中，受人為(wei)(wei)影響容易出(chu)廢(fei)品，從而造成重大經(jing)濟損失。而采(cai)用(yong)CNC加工(gong)(gong)中心(xin)進(jin)行加工(gong)(gong),生產(chan)完全由程(cheng)序自(zi)動控制.避免了(le)長工(gong)(gong)序流程(cheng),減少了(le)硬件(jian)投資(zi)及(ji)人為(wei)(wei)干擾，具有生產(chan)效益高及(ji)質量穩定的特點。

        （3）批(pi)量(liang)生(sheng)產(chan)的工(gong)(gong)(gong)(gong)(gong)件(jian):CNC加(jia)(jia)工(gong)(gong)(gong)(gong)(gong)中心生(sheng)產(chan)的柔性不僅體(ti)現(xian)在對特殊要求(qiu)的快速(su)反應(ying)上，而且可以快速(su)實現(xian)批(pi)量(liang)生(sheng)產(chan)，以提(ti)高市(shi)場競爭能力。CNC加(jia)(jia)工(gong)(gong)(gong)(gong)(gong)中心適合于中小批(pi)量(liang)生(sheng)產(chan)，特別是(shi)小批(pi)量(liang)生(sheng)產(chan)，在應(ying)用CNC加(jia)(jia)工(gong)(gong)(gong)(gong)(gong)中心時。盡量(liang)使批(pi)量(liang)大于經濟(ji)批(pi)量(liang),以達到(dao)良好的經濟(ji)效果。隨著CNC加(jia)(jia)工(gong)(gong)(gong)(gong)(gong)中心的不斷發展，經濟(ji)批(pi)量(liang)越來越小，對一些(xie)復(fu)雜工(gong)(gong)(gong)(gong)(gong)件(jian)，5-10件(jian)就可以生(sheng)產(chan)，甚(shen)至單件(jian)生(sheng)產(chan)時也可以考慮用CNC加(jia)(jia)工(gong)(gong)(gong)(gong)(gong)中心。
