  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)。加(jia)工(gong)(gong)(gong)中心是高度機電一體化的產品(pin)，工(gong)(gong)(gong)件裝夾(jia)后，數控(kong)系統能(neng)控(kong)制機床(chuang)按(an)不同(tong)工(gong)(gong)(gong)序(xu)自動選擇、更(geng)換刀具、自動對(dui)刀、自動改變主軸(zhou)轉(zhuan)速(su)、進給(gei)量(liang)等(deng)，可連(lian)續完成(cheng)鉆(zhan)、鏜、銑、鉸、攻絲(si)等(deng)多種工(gong)(gong)(gong)序(xu)，因而(er)大大減少(shao)了工(gong)(gong)(gong)件裝夾(jia)時間、測量(liang)和(he)機床(chuang)調整等(deng)輔(fu)助(zhu)工(gong)(gong)(gong)序(xu)時間，對(dui)加(jia)工(gong)(gong)(gong)形狀(zhuang)比較復雜，精(jing)度要求較高，品(pin)種更(geng)換頻繁的零件具有良好(hao)的經濟(ji)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(le)進一步發揮這些優點(dian)，數控機床遂(sui)向“工(gong)序集(ji)中”，即一臺數控機床在一次裝夾零件后能(neng)完成多工(gong)序加工(gong)的數控機床(即加工(gong)中心)方面發展。

        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(jian)(批)試切完后，程序和(he)相關生(sheng)產(chan)(chan)(chan)信息可保留(liu)下(xia)(xia)來(lai)，下(xia)(xia)次產(chan)(chan)(chan)品再生(sheng)產(chan)(chan)(chan)時(shi)(shi)，只要(yao)很少的準備(bei)(bei)時(shi)(shi)間就可以開始生(sheng)產(chan)(chan)(chan)。CNC加工(gong)(gong)(gong)(gong)中心工(gong)(gong)(gong)(gong)時(shi)(shi)包括(kuo)準備(bei)(bei)工(gong)(gong)(gong)(gong)時(shi)(shi)和(he)加工(gong)(gong)(gong)(gong)工(gong)(gong)(gong)(gong)時(shi)(shi)，CNC加工(gong)(gong)(gong)(gong)中心把(ba)很長的單件(jian)準備(bei)(bei)工(gong)(gong)(gong)(gong)時(shi)(shi)平(ping)(ping)均(jun)分配到每一個工(gong)(gong)(gong)(gong)件(jian)上，使每次生(sheng)產(chan)(chan)(chan)的平(ping)(ping)均(jun)實際(ji)工(gong)(gong)(gong)(gong)時(shi)(shi)減少，生(sheng)產(chan)(chan)(chan)周期大大縮短。

        （2）高精度(du)工(gong)(gong)件(jian):有(you)些工(gong)(gong)件(jian)需求甚少(shao)，但屬關鍵部(bu)件(jian)，要求精度(du)高且工(gong)(gong)期短，用(yong)傳統工(gong)(gong)藝(yi)需用(yong)多臺機(ji)床協調工(gong)(gong)作(zuo)，其周期長(chang)(chang)、效(xiao)(xiao)率低，在長(chang)(chang)工(gong)(gong)序流程(cheng)(cheng)中，受(shou)人為(wei)影響容易出廢(fei)品，從(cong)而造(zao)成重大經濟損失。而采(cai)用(yong)CNC加工(gong)(gong)中心進行加工(gong)(gong),生產(chan)完(wan)全(quan)由程(cheng)(cheng)序自動控制.避免了長(chang)(chang)工(gong)(gong)序流程(cheng)(cheng),減少(shao)了硬件(jian)投資及人為(wei)干(gan)擾，具有(you)生產(chan)效(xiao)(xiao)益高及質量穩定的(de)特點。

        （3）批(pi)量(liang)(liang)生(sheng)(sheng)(sheng)產的(de)工(gong)件(jian):CNC加(jia)工(gong)中(zhong)心(xin)生(sheng)(sheng)(sheng)產的(de)柔性(xing)不(bu)僅體(ti)現在對特(te)殊要求的(de)快速反應上，而且可(ke)以(yi)快速實(shi)現批(pi)量(liang)(liang)生(sheng)(sheng)(sheng)產，以(yi)提高市(shi)場競爭(zheng)能(neng)力。CNC加(jia)工(gong)中(zhong)心(xin)適(shi)合于中(zhong)小(xiao)批(pi)量(liang)(liang)生(sheng)(sheng)(sheng)產，特(te)別是小(xiao)批(pi)量(liang)(liang)生(sheng)(sheng)(sheng)產，在應用(yong)CNC加(jia)工(gong)中(zhong)心(xin)時。盡量(liang)(liang)使批(pi)量(liang)(liang)大于經(jing)濟批(pi)量(liang)(liang),以(yi)達(da)到良好(hao)的(de)經(jing)濟效果。隨著CNC加(jia)工(gong)中(zhong)心(xin)的(de)不(bu)斷發展，經(jing)濟批(pi)量(liang)(liang)越來越小(xiao)，對一些(xie)復雜工(gong)件(jian)，5-10件(jian)就可(ke)以(yi)生(sheng)(sheng)(sheng)產，甚至(zhi)單(dan)件(jian)生(sheng)(sheng)(sheng)產時也可(ke)以(yi)考(kao)慮用(yong)CNC加(jia)工(gong)中(zhong)心(xin)。
