  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(chuang)。加(jia)工(gong)中心(xin)是高(gao)度(du)(du)機電一體(ti)化的(de)(de)產(chan)品，工(gong)件(jian)裝夾后，數控系統(tong)能(neng)控制機床(chuang)按不同工(gong)序自動選擇、更換刀(dao)具、自動對刀(dao)、自動改變(bian)主軸(zhou)轉速(su)、進(jin)給量等(deng)，可連續(xu)完成鉆、鏜、銑、鉸、攻絲等(deng)多種工(gong)序，因(yin)而大大減(jian)少了工(gong)件(jian)裝夾時(shi)間、測量和機床(chuang)調整等(deng)輔助工(gong)序時(shi)間，對加(jia)工(gong)形狀比較復雜，精度(du)(du)要求較高(gao)，品種更換頻繁的(de)(de)零(ling)件(jian)具有良好的(de)(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(wei)了(le)進一(yi)(yi)步發揮這些優點(dian)，數控機床(chuang)遂(sui)向(xiang)“工序集中”，即一(yi)(yi)臺數控機床(chuang)在(zai)一(yi)(yi)次(ci)裝夾零(ling)件(jian)后(hou)能完(wan)成多工序加工的數控機床(chuang)(即加工中心)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(shou)件(jian)(批(pi))試切完后，程序和相關生(sheng)產(chan)(chan)(chan)信息可保留(liu)下來(lai)，下次產(chan)(chan)(chan)品再生(sheng)產(chan)(chan)(chan)時(shi)，只(zhi)要很少的準備(bei)時(shi)間就(jiu)可以開始生(sheng)產(chan)(chan)(chan)。CNC加工(gong)(gong)中心(xin)工(gong)(gong)時(shi)包括準備(bei)工(gong)(gong)時(shi)和加工(gong)(gong)工(gong)(gong)時(shi)，CNC加工(gong)(gong)中心(xin)把很長的單件(jian)準備(bei)工(gong)(gong)時(shi)平(ping)均(jun)分配到(dao)每一個工(gong)(gong)件(jian)上，使(shi)每次生(sheng)產(chan)(chan)(chan)的平(ping)均(jun)實際工(gong)(gong)時(shi)減少，生(sheng)產(chan)(chan)(chan)周(zhou)期大大縮短(duan)。

        （2）高(gao)精(jing)度(du)(du)工(gong)(gong)(gong)(gong)(gong)件:有些工(gong)(gong)(gong)(gong)(gong)件需求甚少(shao)，但(dan)屬(shu)關鍵部件，要求精(jing)度(du)(du)高(gao)且工(gong)(gong)(gong)(gong)(gong)期短，用(yong)傳統工(gong)(gong)(gong)(gong)(gong)藝(yi)需用(yong)多臺機(ji)床協調工(gong)(gong)(gong)(gong)(gong)作(zuo)，其(qi)周(zhou)期長、效率低，在長工(gong)(gong)(gong)(gong)(gong)序流(liu)程(cheng)中，受人(ren)為影響容易(yi)出(chu)廢(fei)品(pin)，從而(er)造成(cheng)重大經濟(ji)損失。而(er)采用(yong)CNC加工(gong)(gong)(gong)(gong)(gong)中心進(jin)行加工(gong)(gong)(gong)(gong)(gong),生(sheng)產(chan)完(wan)全由程(cheng)序自(zi)動控制.避免了長工(gong)(gong)(gong)(gong)(gong)序流(liu)程(cheng),減少(shao)了硬件投資及人(ren)為干(gan)擾，具(ju)有生(sheng)產(chan)效益高(gao)及質量(liang)穩定的特點。

        （3）批(pi)(pi)量(liang)(liang)(liang)生(sheng)產(chan)的工(gong)(gong)件(jian)(jian)(jian):CNC加(jia)工(gong)(gong)中(zhong)(zhong)(zhong)心(xin)生(sheng)產(chan)的柔性不僅體現(xian)在對特殊要(yao)求的快(kuai)速反應上，而(er)且可(ke)以(yi)(yi)快(kuai)速實現(xian)批(pi)(pi)量(liang)(liang)(liang)生(sheng)產(chan)，以(yi)(yi)提高市場競爭能力。CNC加(jia)工(gong)(gong)中(zhong)(zhong)(zhong)心(xin)適合于(yu)中(zhong)(zhong)(zhong)小(xiao)批(pi)(pi)量(liang)(liang)(liang)生(sheng)產(chan)，特別是(shi)小(xiao)批(pi)(pi)量(liang)(liang)(liang)生(sheng)產(chan)，在應用(yong)(yong)CNC加(jia)工(gong)(gong)中(zhong)(zhong)(zhong)心(xin)時。盡量(liang)(liang)(liang)使批(pi)(pi)量(liang)(liang)(liang)大于(yu)經(jing)濟批(pi)(pi)量(liang)(liang)(liang),以(yi)(yi)達到良好的經(jing)濟效果。隨著CNC加(jia)工(gong)(gong)中(zhong)(zhong)(zhong)心(xin)的不斷發展，經(jing)濟批(pi)(pi)量(liang)(liang)(liang)越(yue)來(lai)越(yue)小(xiao)，對一些復(fu)雜工(gong)(gong)件(jian)(jian)(jian)，5-10件(jian)(jian)(jian)就(jiu)可(ke)以(yi)(yi)生(sheng)產(chan)，甚至(zhi)單件(jian)(jian)(jian)生(sheng)產(chan)時也可(ke)以(yi)(yi)考慮用(yong)(yong)CNC加(jia)工(gong)(gong)中(zhong)(zhong)(zhong)心(xin)。
