  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)中心是(shi)高(gao)度機(ji)電一(yi)體化的(de)(de)產(chan)品，工(gong)件(jian)裝(zhuang)夾后，數(shu)控(kong)系統能控(kong)制(zhi)機(ji)床(chuang)按不同工(gong)序(xu)自動(dong)選擇、更(geng)換(huan)刀(dao)(dao)具(ju)(ju)、自動(dong)對(dui)刀(dao)(dao)、自動(dong)改變主(zhu)軸轉速、進(jin)給量(liang)(liang)等，可連續完(wan)成鉆、鏜、銑、鉸、攻絲等多種(zhong)工(gong)序(xu)，因而大(da)大(da)減少(shao)了工(gong)件(jian)裝(zhuang)夾時(shi)間、測量(liang)(liang)和機(ji)床(chuang)調整等輔助工(gong)序(xu)時(shi)間，對(dui)加(jia)工(gong)形狀比(bi)較(jiao)復雜(za)，精度要求較(jiao)高(gao)，品種(zhong)更(geng)換(huan)頻繁(fan)的(de)(de)零件(jian)具(ju)(ju)有(you)良好的(de)(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步發揮(hui)這些(xie)優點，數控機床(chuang)遂向“工(gong)序集中(zhong)”，即一臺數控機床(chuang)在一次裝夾零件后能(neng)完成多(duo)工(gong)序加工(gong)的(de)數控機床(chuang)(即加工(gong)中(zhong)心(xin))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(批)試切(qie)完后(hou)，程序和(he)相(xiang)關生(sheng)產(chan)(chan)信(xin)息可保留下來，下次產(chan)(chan)品再生(sheng)產(chan)(chan)時(shi)，只要很少的(de)準(zhun)備時(shi)間就(jiu)可以開始生(sheng)產(chan)(chan)。CNC加(jia)工(gong)(gong)(gong)(gong)(gong)中心工(gong)(gong)(gong)(gong)(gong)時(shi)包(bao)括準(zhun)備工(gong)(gong)(gong)(gong)(gong)時(shi)和(he)加(jia)工(gong)(gong)(gong)(gong)(gong)工(gong)(gong)(gong)(gong)(gong)時(shi)，CNC加(jia)工(gong)(gong)(gong)(gong)(gong)中心把很長(chang)的(de)單件準(zhun)備工(gong)(gong)(gong)(gong)(gong)時(shi)平(ping)(ping)均(jun)(jun)分配到每一個工(gong)(gong)(gong)(gong)(gong)件上(shang)，使(shi)每次生(sheng)產(chan)(chan)的(de)平(ping)(ping)均(jun)(jun)實際工(gong)(gong)(gong)(gong)(gong)時(shi)減少，生(sheng)產(chan)(chan)周期大大縮短。

        （2）高(gao)(gao)精度工(gong)(gong)件(jian)(jian):有些工(gong)(gong)件(jian)(jian)需(xu)(xu)求甚少，但屬關鍵部件(jian)(jian)，要求精度高(gao)(gao)且工(gong)(gong)期(qi)短，用(yong)傳統工(gong)(gong)藝(yi)需(xu)(xu)用(yong)多臺(tai)機床(chuang)協調工(gong)(gong)作，其周(zhou)期(qi)長、效率(lv)低，在長工(gong)(gong)序流程中，受(shou)人(ren)為影響容(rong)易(yi)出廢品，從而造成重大經濟損(sun)失。而采用(yong)CNC加(jia)工(gong)(gong)中心進(jin)行加(jia)工(gong)(gong),生產完全由(you)程序自(zi)動控制.避(bi)免了長工(gong)(gong)序流程,減少了硬件(jian)(jian)投資及人(ren)為干擾(rao)，具(ju)有生產效益高(gao)(gao)及質量穩(wen)定的特點(dian)。

        （3）批(pi)(pi)(pi)量(liang)(liang)生產(chan)(chan)(chan)的(de)工(gong)(gong)件(jian)(jian):CNC加工(gong)(gong)中心生產(chan)(chan)(chan)的(de)柔性不僅體現(xian)在對特殊要求的(de)快速(su)反應(ying)上，而且可以(yi)(yi)快速(su)實現(xian)批(pi)(pi)(pi)量(liang)(liang)生產(chan)(chan)(chan)，以(yi)(yi)提高市(shi)場競爭能力。CNC加工(gong)(gong)中心適合于中小批(pi)(pi)(pi)量(liang)(liang)生產(chan)(chan)(chan)，特別是小批(pi)(pi)(pi)量(liang)(liang)生產(chan)(chan)(chan)，在應(ying)用(yong)CNC加工(gong)(gong)中心時。盡量(liang)(liang)使批(pi)(pi)(pi)量(liang)(liang)大于經(jing)濟批(pi)(pi)(pi)量(liang)(liang),以(yi)(yi)達到良好的(de)經(jing)濟效果(guo)。隨著CNC加工(gong)(gong)中心的(de)不斷發展，經(jing)濟批(pi)(pi)(pi)量(liang)(liang)越來越小，對一些(xie)復雜工(gong)(gong)件(jian)(jian)，5-10件(jian)(jian)就可以(yi)(yi)生產(chan)(chan)(chan)，甚至單件(jian)(jian)生產(chan)(chan)(chan)時也(ye)可以(yi)(yi)考慮用(yong)CNC加工(gong)(gong)中心。
