  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)中心是高度機電一體化的(de)產(chan)品，工(gong)(gong)(gong)件裝(zhuang)夾后，數控(kong)系統能控(kong)制(zhi)機床按不(bu)同工(gong)(gong)(gong)序自動選擇、更(geng)(geng)換刀具(ju)、自動對刀、自動改變(bian)主(zhu)軸轉(zhuan)速、進(jin)給(gei)量等，可連續完成鉆、鏜、銑、鉸、攻(gong)絲等多(duo)種(zhong)工(gong)(gong)(gong)序，因而大大減少了工(gong)(gong)(gong)件裝(zhuang)夾時(shi)間、測量和(he)機床調整等輔助工(gong)(gong)(gong)序時(shi)間，對加工(gong)(gong)(gong)形(xing)狀(zhuang)比較復雜，精度要(yao)求較高，品種(zhong)更(geng)(geng)換頻(pin)繁的(de)零件具(ju)有良好的(de)經濟(ji)效(xiao)果(guo)。

        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(bu)發揮(hui)這(zhe)些(xie)優點，數(shu)(shu)控(kong)(kong)機(ji)床遂向“工序集中”，即一臺數(shu)(shu)控(kong)(kong)機(ji)床在一次裝夾零件(jian)后能完成(cheng)多工序加工的數(shu)(shu)控(kong)(kong)機(ji)床(即加工中心)方(fang)面發展(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)試切(qie)完后，程(cheng)序和相關生(sheng)產(chan)(chan)(chan)信息可保留下(xia)來，下(xia)次產(chan)(chan)(chan)品再生(sheng)產(chan)(chan)(chan)時(shi)(shi)，只要很(hen)少的(de)準備時(shi)(shi)間就可以開始生(sheng)產(chan)(chan)(chan)。CNC加(jia)工(gong)(gong)(gong)(gong)中心(xin)工(gong)(gong)(gong)(gong)時(shi)(shi)包(bao)括(kuo)準備工(gong)(gong)(gong)(gong)時(shi)(shi)和加(jia)工(gong)(gong)(gong)(gong)工(gong)(gong)(gong)(gong)時(shi)(shi)，CNC加(jia)工(gong)(gong)(gong)(gong)中心(xin)把很(hen)長的(de)單件(jian)準備工(gong)(gong)(gong)(gong)時(shi)(shi)平(ping)均分配到每一個工(gong)(gong)(gong)(gong)件(jian)上，使每次生(sheng)產(chan)(chan)(chan)的(de)平(ping)均實際工(gong)(gong)(gong)(gong)時(shi)(shi)減(jian)少，生(sheng)產(chan)(chan)(chan)周(zhou)期大大縮短。

       ; （2）高精度工(gong)(gong)件(jian):有些工(gong)(gong)件(jian)需求(qiu)甚(shen)少(shao)，但(dan)屬關鍵部件(jian)，要求(qiu)精度高且工(gong)(gong)期(qi)(qi)短(duan)，用(yong)傳統工(gong)(gong)藝需用(yong)多臺機(ji)床協調工(gong)(gong)作，其周(zhou)期(qi)(qi)長(chang)、效(xiao)率(lv)低，在(zai)長(chang)工(gong)(gong)序(xu)(xu)流程(cheng)中(zhong)，受人為影響容易出廢(fei)品，從而造成(cheng)重大經(jing)濟(ji)損失(shi)。而采(cai)用(yong)CNC加工(gong)(gong)中(zhong)心進行(xing)加工(gong)(gong),生產完全由(you)程(cheng)序(xu)(xu)自動控制.避免了長(chang)工(gong)(gong)序(xu)(xu)流程(cheng),減少(shao)了硬件(jian)投資(zi)及(ji)人為干擾，具有生產效(xiao)益高及(ji)質量(liang)穩定的特點。

        （3）批(pi)(pi)量(liang)(liang)生(sheng)產(chan)(chan)的工(gong)件(jian):CNC加工(gong)中(zhong)(zhong)心(xin)生(sheng)產(chan)(chan)的柔性(xing)不(bu)僅體(ti)現在對特殊要求的快速(su)反(fan)應上，而(er)且可(ke)以(yi)(yi)快速(su)實現批(pi)(pi)量(liang)(liang)生(sheng)產(chan)(chan)，以(yi)(yi)提高市場競爭能力(li)。CNC加工(gong)中(zhong)(zhong)心(xin)適合(he)于中(zhong)(zhong)小批(pi)(pi)量(liang)(liang)生(sheng)產(chan)(chan)，特別(bie)是小批(pi)(pi)量(liang)(liang)生(sheng)產(chan)(chan)，在應用CNC加工(gong)中(zhong)(zhong)心(xin)時。盡量(liang)(liang)使批(pi)(pi)量(liang)(liang)大于經(jing)濟批(pi)(pi)量(liang)(liang),以(yi)(yi)達到良(liang)好的經(jing)濟效果。隨著CNC加工(gong)中(zhong)(zhong)心(xin)的不(bu)斷(duan)發展，經(jing)濟批(pi)(pi)量(liang)(liang)越(yue)來越(yue)小，對一些(xie)復雜(za)工(gong)件(jian)，5-10件(jian)就可(ke)以(yi)(yi)生(sheng)產(chan)(chan)，甚至單件(jian)生(sheng)產(chan)(chan)時也(ye)可(ke)以(yi)(yi)考(kao)慮(lv)用CNC加工(gong)中(zhong)(zhong)心(xin)。
