  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)(gong)中(zhong)心是高(gao)度機(ji)(ji)電一(yi)體化(hua)的(de)產品，工(gong)(gong)件裝夾后，數控(kong)系統能控(kong)制機(ji)(ji)床(chuang)(chuang)按不同工(gong)(gong)序自(zi)動(dong)(dong)選擇、更換刀(dao)具、自(zi)動(dong)(dong)對(dui)刀(dao)、自(zi)動(dong)(dong)改(gai)變主軸轉速、進給量(liang)(liang)等(deng)，可連(lian)續完(wan)成鉆、鏜、銑(xian)、鉸、攻(gong)絲等(deng)多種工(gong)(gong)序，因而大大減少了工(gong)(gong)件裝夾時(shi)間、測量(liang)(liang)和(he)機(ji)(ji)床(chuang)(chuang)調(diao)整等(deng)輔助工(gong)(gong)序時(shi)間，對(dui)加工(gong)(gong)形(xing)狀(zhuang)比較復(fu)雜，精(jing)度要求(qiu)較高(gao)，品種更換頻繁的(de)零件具有(you)良好的(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了進一(yi)步發揮這些優點，數控(kong)(kong)機床遂向“工序集中(zhong)”，即一(yi)臺(tai)數控(kong)(kong)機床在一(yi)次裝夾零件后能(neng)完成多工序加工的數控(kong)(kong)機床(即加工中(zhong)心)方(fang)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，首件(批)試(shi)切完后，程(cheng)序和(he)相關生(sheng)產信息可保留下來(lai)，下次產品再生(sheng)產時(shi)(shi)(shi)，只要很(hen)少的(de)準備時(shi)(shi)(shi)間就可以開始生(sheng)產。CNC加(jia)(jia)工(gong)(gong)(gong)(gong)中心工(gong)(gong)(gong)(gong)時(shi)(shi)(shi)包括準備工(gong)(gong)(gong)(gong)時(shi)(shi)(shi)和(he)加(jia)(jia)工(gong)(gong)(gong)(gong)工(gong)(gong)(gong)(gong)時(shi)(shi)(shi)，CNC加(jia)(jia)工(gong)(gong)(gong)(gong)中心把很(hen)長的(de)單(dan)件準備工(gong)(gong)(gong)(gong)時(shi)(shi)(shi)平(ping)均分配到每一個工(gong)(gong)(gong)(gong)件上，使每次生(sheng)產的(de)平(ping)均實際工(gong)(gong)(gong)(gong)時(shi)(shi)(shi)減少，生(sheng)產周(zhou)期大大縮短。

        （2）高(gao)精度工(gong)(gong)(gong)件(jian):有些工(gong)(gong)(gong)件(jian)需求甚少，但屬(shu)關鍵部件(jian)，要求精度高(gao)且(qie)工(gong)(gong)(gong)期(qi)短(duan)，用(yong)傳統工(gong)(gong)(gong)藝需用(yong)多臺機床協調工(gong)(gong)(gong)作，其周(zhou)期(qi)長、效(xiao)率(lv)低，在長工(gong)(gong)(gong)序(xu)流程中(zhong)，受人(ren)為影響容易出廢品，從而(er)造成重大經濟損失。而(er)采(cai)用(yong)CNC加工(gong)(gong)(gong)中(zhong)心進行(xing)加工(gong)(gong)(gong),生產完全(quan)由(you)程序(xu)自動控制.避免了長工(gong)(gong)(gong)序(xu)流程,減(jian)少了硬件(jian)投資及人(ren)為干擾，具有生產效(xiao)益高(gao)及質量穩(wen)定的特點。

        （3）批(pi)(pi)(pi)(pi)量(liang)(liang)生(sheng)(sheng)(sheng)產(chan)(chan)的(de)(de)工(gong)(gong)件(jian)(jian):CNC加工(gong)(gong)中(zhong)(zhong)心生(sheng)(sheng)(sheng)產(chan)(chan)的(de)(de)柔(rou)性(xing)不僅(jin)體現在對特(te)殊要求的(de)(de)快(kuai)速反應上，而且可(ke)以(yi)(yi)快(kuai)速實現批(pi)(pi)(pi)(pi)量(liang)(liang)生(sheng)(sheng)(sheng)產(chan)(chan)，以(yi)(yi)提高市場競(jing)爭能力。CNC加工(gong)(gong)中(zhong)(zhong)心適合于中(zhong)(zhong)小批(pi)(pi)(pi)(pi)量(liang)(liang)生(sheng)(sheng)(sheng)產(chan)(chan)，特(te)別(bie)是小批(pi)(pi)(pi)(pi)量(liang)(liang)生(sheng)(sheng)(sheng)產(chan)(chan)，在應用(yong)CNC加工(gong)(gong)中(zhong)(zhong)心時(shi)。盡量(liang)(liang)使批(pi)(pi)(pi)(pi)量(liang)(liang)大于經(jing)(jing)濟(ji)(ji)批(pi)(pi)(pi)(pi)量(liang)(liang),以(yi)(yi)達(da)到良好的(de)(de)經(jing)(jing)濟(ji)(ji)效果。隨著CNC加工(gong)(gong)中(zhong)(zhong)心的(de)(de)不斷發展，經(jing)(jing)濟(ji)(ji)批(pi)(pi)(pi)(pi)量(liang)(liang)越(yue)來越(yue)小，對一些(xie)復雜工(gong)(gong)件(jian)(jian)，5-10件(jian)(jian)就可(ke)以(yi)(yi)生(sheng)(sheng)(sheng)產(chan)(chan)，甚(shen)至單(dan)件(jian)(jian)生(sheng)(sheng)(sheng)產(chan)(chan)時(shi)也可(ke)以(yi)(yi)考慮(lv)用(yong)CNC加工(gong)(gong)中(zhong)(zhong)心。
