  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)(chuang)。加(jia)工(gong)中心是高度(du)機電一體化的產品，工(gong)件(jian)裝夾后，數(shu)控系(xi)統能控制(zhi)機床(chuang)(chuang)按不同(tong)工(gong)序自動選擇、更換刀具、自動對(dui)刀、自動改變主軸轉速、進給量等(deng)，可(ke)連(lian)續完成鉆、鏜(tang)、銑、鉸、攻絲(si)等(deng)多種(zhong)工(gong)序，因(yin)而大大減少了工(gong)件(jian)裝夾時間、測量和(he)機床(chuang)(chuang)調(diao)整等(deng)輔助工(gong)序時間，對(dui)加(jia)工(gong)形狀比較復(fu)雜，精度(du)要(yao)求較高，品種(zhong)更換頻繁的零件(jian)具有良(liang)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(jin)一(yi)步發(fa)揮這些優點，數(shu)(shu)控機(ji)床遂向(xiang)“工(gong)序集中(zhong)”，即一(yi)臺(tai)數(shu)(shu)控機(ji)床在一(yi)次裝夾零(ling)件后能完成多工(gong)序加工(gong)的數(shu)(shu)控機(ji)床(即加工(gong)中(zhong)心)方面發(fa)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(shi)切(qie)完后，程(cheng)序(xu)和相關生(sheng)產(chan)(chan)信息可(ke)保留(liu)下來，下次產(chan)(chan)品(pin)再生(sheng)產(chan)(chan)時，只要很少的(de)準備(bei)(bei)時間就可(ke)以開始(shi)生(sheng)產(chan)(chan)。CNC加(jia)工(gong)(gong)(gong)中(zhong)心工(gong)(gong)(gong)時包括(kuo)準備(bei)(bei)工(gong)(gong)(gong)時和加(jia)工(gong)(gong)(gong)工(gong)(gong)(gong)時，CNC加(jia)工(gong)(gong)(gong)中(zhong)心把很長的(de)單(dan)件準備(bei)(bei)工(gong)(gong)(gong)時平(ping)均(jun)分配到每(mei)一個工(gong)(gong)(gong)件上，使每(mei)次生(sheng)產(chan)(chan)的(de)平(ping)均(jun)實際工(gong)(gong)(gong)時減(jian)少，生(sheng)產(chan)(chan)周期大(da)(da)大(da)(da)縮短(duan)。

        （2）高精度工件:有(you)(you)些工件需求甚少，但(dan)屬關鍵(jian)部件，要求精度高且工期(qi)短，用(yong)傳統工藝需用(yong)多(duo)臺機床協調工作，其周期(qi)長、效率低，在(zai)長工序(xu)(xu)流程中(zhong)，受人(ren)為(wei)影(ying)響容易出廢品，從而造成重(zhong)大經濟損失。而采(cai)用(yong)CNC加工中(zhong)心進行(xing)加工,生產完全由程序(xu)(xu)自(zi)動控(kong)制.避免了長工序(xu)(xu)流程,減少了硬件投(tou)資及(ji)人(ren)為(wei)干擾，具有(you)(you)生產效益高及(ji)質(zhi)量穩(wen)定(ding)的特點。

        （3）批(pi)(pi)量(liang)(liang)(liang)生(sheng)(sheng)(sheng)產(chan)(chan)的(de)工(gong)(gong)(gong)件(jian):CNC加(jia)(jia)(jia)工(gong)(gong)(gong)中(zhong)(zhong)(zhong)(zhong)心(xin)(xin)生(sheng)(sheng)(sheng)產(chan)(chan)的(de)柔性不僅體現在對特(te)殊要(yao)求的(de)快(kuai)速反應上，而且可以(yi)(yi)快(kuai)速實(shi)現批(pi)(pi)量(liang)(liang)(liang)生(sheng)(sheng)(sheng)產(chan)(chan)，以(yi)(yi)提高市場競爭(zheng)能力。CNC加(jia)(jia)(jia)工(gong)(gong)(gong)中(zhong)(zhong)(zhong)(zhong)心(xin)(xin)適(shi)合于(yu)中(zhong)(zhong)(zhong)(zhong)小批(pi)(pi)量(liang)(liang)(liang)生(sheng)(sheng)(sheng)產(chan)(chan)，特(te)別是小批(pi)(pi)量(liang)(liang)(liang)生(sheng)(sheng)(sheng)產(chan)(chan)，在應用(yong)CNC加(jia)(jia)(jia)工(gong)(gong)(gong)中(zhong)(zhong)(zhong)(zhong)心(xin)(xin)時。盡量(liang)(liang)(liang)使(shi)批(pi)(pi)量(liang)(liang)(liang)大于(yu)經(jing)(jing)濟(ji)(ji)批(pi)(pi)量(liang)(liang)(liang),以(yi)(yi)達到良(liang)好的(de)經(jing)(jing)濟(ji)(ji)效果。隨著CNC加(jia)(jia)(jia)工(gong)(gong)(gong)中(zhong)(zhong)(zhong)(zhong)心(xin)(xin)的(de)不斷(duan)發展，經(jing)(jing)濟(ji)(ji)批(pi)(pi)量(liang)(liang)(liang)越來越小，對一些(xie)復雜工(gong)(gong)(gong)件(jian)，5-10件(jian)就可以(yi)(yi)生(sheng)(sheng)(sheng)產(chan)(chan)，甚至單(dan)件(jian)生(sheng)(sheng)(sheng)產(chan)(chan)時也可以(yi)(yi)考慮用(yong)CNC加(jia)(jia)(jia)工(gong)(gong)(gong)中(zhong)(zhong)(zhong)(zhong)心(xin)(xin)。
