  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。加工(gong)(gong)(gong)中心是高度機(ji)電(dian)一體化(hua)的(de)產品(pin)，工(gong)(gong)(gong)件(jian)裝夾(jia)后，數(shu)控(kong)系統能控(kong)制(zhi)機(ji)床按不同工(gong)(gong)(gong)序(xu)自(zi)(zi)動(dong)選擇、更(geng)換(huan)刀具、自(zi)(zi)動(dong)對(dui)刀、自(zi)(zi)動(dong)改變主(zhu)軸(zhou)轉(zhuan)速、進給(gei)量等(deng)，可連續完成鉆、鏜、銑、鉸(jiao)、攻絲等(deng)多種(zhong)工(gong)(gong)(gong)序(xu)，因而大(da)(da)大(da)(da)減少(shao)了(le)工(gong)(gong)(gong)件(jian)裝夾(jia)時(shi)間、測量和機(ji)床調整等(deng)輔助工(gong)(gong)(gong)序(xu)時(shi)間，對(dui)加工(gong)(gong)(gong)形狀(zhuang)比較(jiao)復雜，精度要求(qiu)較(jiao)高，品(pin)種(zhong)更(geng)換(huan)頻繁的(de)零件(jian)具有(you)良(liang)好的(de)經濟(ji)效(xiao)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(wei)了進一(yi)步發(fa)揮這些優點，數(shu)控(kong)(kong)機(ji)床遂向“工(gong)序集中(zhong)”，即(ji)一(yi)臺數(shu)控(kong)(kong)機(ji)床在(zai)一(yi)次裝(zhuang)夾零(ling)件后能完成多工(gong)序加工(gong)的數(shu)控(kong)(kong)機(ji)床(即(ji)加工(gong)中(zhong)心)方面(mian)發(fa)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(shou)件(批)試(shi)切完(wan)后(hou)，程序(xu)和相(xiang)關(guan)生(sheng)產(chan)(chan)信息(xi)可(ke)(ke)保(bao)留下來，下次產(chan)(chan)品再生(sheng)產(chan)(chan)時，只要很少(shao)的準備時間就(jiu)可(ke)(ke)以(yi)開始生(sheng)產(chan)(chan)。CNC加(jia)工(gong)(gong)(gong)中(zhong)心(xin)工(gong)(gong)(gong)時包括(kuo)準備工(gong)(gong)(gong)時和加(jia)工(gong)(gong)(gong)工(gong)(gong)(gong)時，CNC加(jia)工(gong)(gong)(gong)中(zhong)心(xin)把很長的單件準備工(gong)(gong)(gong)時平(ping)均(jun)分配到每一個工(gong)(gong)(gong)件上(shang)，使每次生(sheng)產(chan)(chan)的平(ping)均(jun)實際工(gong)(gong)(gong)時減少(shao)，生(sheng)產(chan)(chan)周期大大縮短(duan)。

        （2）高(gao)(gao)精(jing)度(du)工(gong)(gong)(gong)件(jian):有些工(gong)(gong)(gong)件(jian)需求甚少，但屬關鍵部件(jian)，要求精(jing)度(du)高(gao)(gao)且工(gong)(gong)(gong)期短，用(yong)(yong)傳統工(gong)(gong)(gong)藝(yi)需用(yong)(yong)多臺(tai)機床協調工(gong)(gong)(gong)作，其周期長(chang)、效率低，在(zai)長(chang)工(gong)(gong)(gong)序(xu)流(liu)(liu)程中，受(shou)人(ren)為影(ying)響容易出廢品，從而(er)造(zao)成(cheng)重大經濟損失。而(er)采用(yong)(yong)CNC加工(gong)(gong)(gong)中心(xin)進行加工(gong)(gong)(gong),生產完(wan)全由程序(xu)自(zi)動控制(zhi).避免(mian)了(le)(le)長(chang)工(gong)(gong)(gong)序(xu)流(liu)(liu)程,減少了(le)(le)硬件(jian)投資及(ji)人(ren)為干擾(rao)，具有生產效益高(gao)(gao)及(ji)質量穩定的特點。

        （3）批量(liang)(liang)生(sheng)(sheng)產(chan)(chan)的工(gong)(gong)件(jian):CNC加(jia)工(gong)(gong)中(zhong)(zhong)(zhong)(zhong)心(xin)生(sheng)(sheng)產(chan)(chan)的柔性(xing)不僅體現在對特殊要(yao)求的快速(su)反應上，而且可以(yi)(yi)快速(su)實現批量(liang)(liang)生(sheng)(sheng)產(chan)(chan)，以(yi)(yi)提高市場(chang)競(jing)爭能力。CNC加(jia)工(gong)(gong)中(zhong)(zhong)(zhong)(zhong)心(xin)適合于(yu)中(zhong)(zhong)(zhong)(zhong)小批量(liang)(liang)生(sheng)(sheng)產(chan)(chan)，特別是小批量(liang)(liang)生(sheng)(sheng)產(chan)(chan)，在應用(yong)CNC加(jia)工(gong)(gong)中(zhong)(zhong)(zhong)(zhong)心(xin)時。盡量(liang)(liang)使批量(liang)(liang)大(da)于(yu)經(jing)濟(ji)批量(liang)(liang),以(yi)(yi)達到良好的經(jing)濟(ji)效果。隨著CNC加(jia)工(gong)(gong)中(zhong)(zhong)(zhong)(zhong)心(xin)的不斷發展，經(jing)濟(ji)批量(liang)(liang)越來越小，對一些復雜(za)工(gong)(gong)件(jian)，5-10件(jian)就可以(yi)(yi)生(sheng)(sheng)產(chan)(chan)，甚至(zhi)單件(jian)生(sheng)(sheng)產(chan)(chan)時也可以(yi)(yi)考(kao)慮用(yong)CNC加(jia)工(gong)(gong)中(zhong)(zhong)(zhong)(zhong)心(xin)。
