  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)。加工(gong)(gong)中心是高(gao)度機電一(yi)體(ti)化(hua)的產(chan)品，工(gong)(gong)件(jian)裝夾后，數控系(xi)統(tong)能控制機床(chuang)按不(bu)同工(gong)(gong)序(xu)自(zi)動(dong)選擇、更換刀具、自(zi)動(dong)對刀、自(zi)動(dong)改變主軸轉速(su)、進給(gei)量(liang)等，可連續完成鉆、鏜、銑(xian)、鉸、攻(gong)絲等多(duo)種工(gong)(gong)序(xu)，因而大大減少了工(gong)(gong)件(jian)裝夾時間(jian)、測量(liang)和機床(chuang)調整等輔助工(gong)(gong)序(xu)時間(jian)，對加工(gong)(gong)形狀比(bi)較(jiao)復雜，精(jing)度要求較(jiao)高(gao)，品種更換頻繁的零件(jian)具有良好的經濟效果(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)發揮這些優點(dian)，數控(kong)機床(chuang)遂向“工(gong)序集(ji)中”，即(ji)一臺數控(kong)機床(chuang)在一次裝夾零(ling)件(jian)后(hou)能完成多(duo)工(gong)序加(jia)工(gong)的數控(kong)機床(chuang)(即(ji)加(jia)工(gong)中心)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(qie)完后，程序和相關生(sheng)產信息可保(bao)留(liu)下(xia)來(lai)，下(xia)次產品再生(sheng)產時(shi)(shi)(shi)，只要(yao)很少(shao)的準(zhun)備(bei)時(shi)(shi)(shi)間就可以開始生(sheng)產。CNC加(jia)(jia)工(gong)(gong)(gong)(gong)中心(xin)工(gong)(gong)(gong)(gong)時(shi)(shi)(shi)包(bao)括準(zhun)備(bei)工(gong)(gong)(gong)(gong)時(shi)(shi)(shi)和加(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(xin)把很長的單件(jian)準(zhun)備(bei)工(gong)(gong)(gong)(gong)時(shi)(shi)(shi)平均(jun)分配到每一個工(gong)(gong)(gong)(gong)件(jian)上，使每次生(sheng)產的平均(jun)實際(ji)工(gong)(gong)(gong)(gong)時(shi)(shi)(shi)減少(shao)，生(sheng)產周期大大縮短。

        （2）高精度工(gong)(gong)(gong)件:有些工(gong)(gong)(gong)件需求(qiu)甚少(shao)，但屬關鍵部件，要求(qiu)精度高且工(gong)(gong)(gong)期(qi)短(duan)，用傳統工(gong)(gong)(gong)藝需用多臺機床協調工(gong)(gong)(gong)作，其周期(qi)長、效(xiao)率(lv)低，在長工(gong)(gong)(gong)序(xu)流程中，受人為(wei)影響容易出廢品，從而(er)造成重大經濟損(sun)失。而(er)采用CNC加工(gong)(gong)(gong)中心(xin)進行加工(gong)(gong)(gong),生產(chan)完(wan)全(quan)由(you)程序(xu)自(zi)動(dong)控制.避(bi)免了長工(gong)(gong)(gong)序(xu)流程,減(jian)少(shao)了硬件投資及人為(wei)干擾，具(ju)有生產(chan)效(xiao)益高及質量穩定(ding)的特點。

        （3）批(pi)(pi)量(liang)(liang)生(sheng)產(chan)的(de)工(gong)(gong)(gong)(gong)件(jian):CNC加工(gong)(gong)(gong)(gong)中心(xin)生(sheng)產(chan)的(de)柔(rou)性不(bu)僅體現在(zai)對特(te)殊要(yao)求的(de)快速反應上，而且(qie)可以(yi)快速實現批(pi)(pi)量(liang)(liang)生(sheng)產(chan)，以(yi)提高市場(chang)競爭能力(li)。CNC加工(gong)(gong)(gong)(gong)中心(xin)適(shi)合于(yu)中小批(pi)(pi)量(liang)(liang)生(sheng)產(chan)，特(te)別是小批(pi)(pi)量(liang)(liang)生(sheng)產(chan)，在(zai)應用CNC加工(gong)(gong)(gong)(gong)中心(xin)時(shi)。盡(jin)量(liang)(liang)使批(pi)(pi)量(liang)(liang)大于(yu)經(jing)濟批(pi)(pi)量(liang)(liang),以(yi)達到良好的(de)經(jing)濟效果。隨著CNC加工(gong)(gong)(gong)(gong)中心(xin)的(de)不(bu)斷發展，經(jing)濟批(pi)(pi)量(liang)(liang)越來(lai)越小，對一些復(fu)雜(za)工(gong)(gong)(gong)(gong)件(jian)，5-10件(jian)就(jiu)可以(yi)生(sheng)產(chan)，甚至單件(jian)生(sheng)產(chan)時(shi)也(ye)可以(yi)考慮用CNC加工(gong)(gong)(gong)(gong)中心(xin)。
