  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。加工中心是(shi)高度機電(dian)一體化的產(chan)品，工件裝夾(jia)后，數控(kong)系(xi)統能控(kong)制機床按不同工序自(zi)(zi)動選擇、更換刀具、自(zi)(zi)動對刀、自(zi)(zi)動改變主(zhu)軸轉速(su)、進給量等(deng)，可連續(xu)完成鉆、鏜、銑、鉸、攻絲(si)等(deng)多種工序，因而大大減少了(le)工件裝夾(jia)時間、測(ce)量和機床調整(zheng)等(deng)輔助(zhu)工序時間，對加工形狀比較復(fu)雜，精度要求較高，品種更換頻繁的零件具有良好的經(jing)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進一(yi)步(bu)發(fa)揮這些優(you)點(dian)，數控(kong)機床(chuang)(chuang)遂向(xiang)“工序(xu)集(ji)中(zhong)”，即(ji)一(yi)臺數控(kong)機床(chuang)(chuang)在一(yi)次(ci)裝夾零件(jian)后能完成多工序(xu)加工的數控(kong)機床(chuang)(chuang)(即(ji)加工中(zhong)心(xin))方(fang)面(mian)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)試切(qie)完(wan)后(hou)，程(cheng)序和相關生(sheng)產(chan)信息(xi)可(ke)保留下來，下次產(chan)品(pin)再生(sheng)產(chan)時(shi)，只要很少(shao)的準備(bei)(bei)時(shi)間就可(ke)以開始生(sheng)產(chan)。CNC加工(gong)(gong)中心工(gong)(gong)時(shi)包括準備(bei)(bei)工(gong)(gong)時(shi)和加工(gong)(gong)工(gong)(gong)時(shi)，CNC加工(gong)(gong)中心把(ba)很長的單件準備(bei)(bei)工(gong)(gong)時(shi)平均分配到(dao)每一個工(gong)(gong)件上，使每次生(sheng)產(chan)的平均實際(ji)工(gong)(gong)時(shi)減少(shao)，生(sheng)產(chan)周期大大縮短。

        （2）高(gao)精(jing)(jing)度工(gong)(gong)(gong)件(jian):有些工(gong)(gong)(gong)件(jian)需求(qiu)甚少(shao)，但屬(shu)關鍵部件(jian)，要(yao)求(qiu)精(jing)(jing)度高(gao)且工(gong)(gong)(gong)期(qi)短，用(yong)傳統(tong)工(gong)(gong)(gong)藝需用(yong)多臺(tai)機床協調(diao)工(gong)(gong)(gong)作，其(qi)周期(qi)長、效率低，在長工(gong)(gong)(gong)序(xu)流程(cheng)中，受(shou)人為影響容易出廢品(pin)，從而造成重大經(jing)濟損(sun)失(shi)。而采用(yong)CNC加工(gong)(gong)(gong)中心(xin)進行加工(gong)(gong)(gong),生產(chan)完全由(you)程(cheng)序(xu)自動控制.避免了(le)長工(gong)(gong)(gong)序(xu)流程(cheng),減少(shao)了(le)硬件(jian)投資及人為干(gan)擾，具(ju)有生產(chan)效益高(gao)及質量(liang)穩定(ding)的特點。

        （3）批(pi)量生(sheng)(sheng)產(chan)(chan)的(de)(de)工(gong)(gong)(gong)件(jian):CNC加(jia)(jia)工(gong)(gong)(gong)中(zhong)心(xin)生(sheng)(sheng)產(chan)(chan)的(de)(de)柔性不(bu)僅(jin)體現(xian)在(zai)(zai)對(dui)特殊要求的(de)(de)快速反應上(shang)，而且可(ke)以快速實現(xian)批(pi)量生(sheng)(sheng)產(chan)(chan)，以提高(gao)市場(chang)競爭能力。CNC加(jia)(jia)工(gong)(gong)(gong)中(zhong)心(xin)適合于中(zhong)小(xiao)批(pi)量生(sheng)(sheng)產(chan)(chan)，特別(bie)是小(xiao)批(pi)量生(sheng)(sheng)產(chan)(chan)，在(zai)(zai)應用(yong)CNC加(jia)(jia)工(gong)(gong)(gong)中(zhong)心(xin)時。盡量使(shi)批(pi)量大(da)于經濟批(pi)量,以達到良(liang)好的(de)(de)經濟效(xiao)果。隨(sui)著CNC加(jia)(jia)工(gong)(gong)(gong)中(zhong)心(xin)的(de)(de)不(bu)斷發展，經濟批(pi)量越來越小(xiao)，對(dui)一些復雜工(gong)(gong)(gong)件(jian)，5-10件(jian)就可(ke)以生(sheng)(sheng)產(chan)(chan)，甚(shen)至單件(jian)生(sheng)(sheng)產(chan)(chan)時也可(ke)以考慮用(yong)CNC加(jia)(jia)工(gong)(gong)(gong)中(zhong)心(xin)。
