  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)。加工(gong)中(zhong)心是高(gao)度(du)機電(dian)一體化的(de)(de)產(chan)品(pin)，工(gong)件(jian)裝夾后，數控(kong)系統能控(kong)制機床(chuang)(chuang)按(an)不同工(gong)序(xu)自(zi)動(dong)選擇(ze)、更換刀具、自(zi)動(dong)對刀、自(zi)動(dong)改變主軸轉速、進給量等(deng)，可連(lian)續完成鉆、鏜、銑、鉸(jiao)、攻絲等(deng)多種工(gong)序(xu)，因而大大減少(shao)了(le)工(gong)件(jian)裝夾時(shi)間、測量和(he)機床(chuang)(chuang)調(diao)整等(deng)輔助工(gong)序(xu)時(shi)間，對加工(gong)形狀比(bi)較復雜，精度(du)要求(qiu)較高(gao)，品(pin)種更換頻繁的(de)(de)零(ling)件(jian)具有良好的(de)(de)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(jia)為(wei)了(le)進(jin)一步發揮這些(xie)優點，數控(kong)(kong)機(ji)床遂(sui)向“工序集中(zhong)”，即(ji)一臺數控(kong)(kong)機(ji)床在一次裝(zhuang)夾零件后能完成(cheng)多工序加工的數控(kong)(kong)機(ji)床(即(ji)加工中(zhong)心)方面發展(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)試切完后(hou)，程序(xu)和相關生(sheng)(sheng)產(chan)(chan)信息可保留下(xia)來，下(xia)次產(chan)(chan)品再生(sheng)(sheng)產(chan)(chan)時(shi)，只(zhi)要(yao)很少的準備時(shi)間就(jiu)可以(yi)開(kai)始(shi)生(sheng)(sheng)產(chan)(chan)。CNC加工(gong)(gong)中(zhong)心(xin)工(gong)(gong)時(shi)包括(kuo)準備工(gong)(gong)時(shi)和加工(gong)(gong)工(gong)(gong)時(shi)，CNC加工(gong)(gong)中(zhong)心(xin)把(ba)很長的單(dan)件(jian)準備工(gong)(gong)時(shi)平均(jun)分配(pei)到每(mei)一(yi)個工(gong)(gong)件(jian)上，使每(mei)次生(sheng)(sheng)產(chan)(chan)的平均(jun)實際工(gong)(gong)時(shi)減(jian)少，生(sheng)(sheng)產(chan)(chan)周期(qi)大大縮短。

        （2）高精度工(gong)(gong)件(jian):有些工(gong)(gong)件(jian)需求(qiu)甚少(shao)，但屬關鍵(jian)部件(jian)，要求(qiu)精度高且工(gong)(gong)期(qi)短，用(yong)傳(chuan)統工(gong)(gong)藝需用(yong)多臺機床(chuang)協調(diao)工(gong)(gong)作，其周期(qi)長、效率(lv)低，在(zai)長工(gong)(gong)序流(liu)程(cheng)(cheng)中(zhong)，受人為(wei)影響容易出廢品，從而造成重大(da)經濟損失。而采用(yong)CNC加(jia)工(gong)(gong)中(zhong)心進行加(jia)工(gong)(gong),生產完(wan)全由(you)程(cheng)(cheng)序自動控(kong)制(zhi).避免了長工(gong)(gong)序流(liu)程(cheng)(cheng),減少(shao)了硬(ying)件(jian)投資及人為(wei)干擾，具(ju)有生產效益高及質量穩定的特點。

        （3）批(pi)量(liang)(liang)(liang)生(sheng)(sheng)(sheng)產(chan)(chan)(chan)的工(gong)(gong)(gong)件(jian)(jian):CNC加工(gong)(gong)(gong)中(zhong)心(xin)生(sheng)(sheng)(sheng)產(chan)(chan)(chan)的柔性不僅體現(xian)在對特殊要求的快速反應上，而且可以快速實現(xian)批(pi)量(liang)(liang)(liang)生(sheng)(sheng)(sheng)產(chan)(chan)(chan)，以提高市場競爭能力。CNC加工(gong)(gong)(gong)中(zhong)心(xin)適(shi)合于(yu)中(zhong)小批(pi)量(liang)(liang)(liang)生(sheng)(sheng)(sheng)產(chan)(chan)(chan)，特別(bie)是小批(pi)量(liang)(liang)(liang)生(sheng)(sheng)(sheng)產(chan)(chan)(chan)，在應用(yong)CNC加工(gong)(gong)(gong)中(zhong)心(xin)時(shi)。盡量(liang)(liang)(liang)使批(pi)量(liang)(liang)(liang)大(da)于(yu)經(jing)濟批(pi)量(liang)(liang)(liang),以達到良好的經(jing)濟效果。隨著CNC加工(gong)(gong)(gong)中(zhong)心(xin)的不斷發展，經(jing)濟批(pi)量(liang)(liang)(liang)越來越小，對一些復雜工(gong)(gong)(gong)件(jian)(jian)，5-10件(jian)(jian)就可以生(sheng)(sheng)(sheng)產(chan)(chan)(chan)，甚至單件(jian)(jian)生(sheng)(sheng)(sheng)產(chan)(chan)(chan)時(shi)也可以考慮用(yong)CNC加工(gong)(gong)(gong)中(zhong)心(xin)。
