  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(shi)高度機電一體化的產品，工(gong)(gong)件(jian)裝夾(jia)后，數控系(xi)統能控制機床(chuang)按不同(tong)工(gong)(gong)序(xu)自(zi)動(dong)選擇、更換(huan)刀具、自(zi)動(dong)對(dui)刀、自(zi)動(dong)改變主軸轉速、進給量等(deng)，可連續(xu)完成鉆(zhan)、鏜、銑、鉸、攻(gong)絲等(deng)多(duo)種(zhong)(zhong)工(gong)(gong)序(xu)，因而大大減(jian)少了工(gong)(gong)件(jian)裝夾(jia)時間(jian)(jian)、測量和(he)機床(chuang)調整等(deng)輔(fu)助工(gong)(gong)序(xu)時間(jian)(jian)，對(dui)加工(gong)(gong)形狀(zhuang)比較復雜，精度要求(qiu)較高，品種(zhong)(zhong)更換(huan)頻繁的零(ling)件(jian)具有良好的經濟效果。

        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(fa)揮這些優點，數控機床(chuang)遂向“工序集中”，即一臺數控機床(chuang)在一次裝(zhuang)夾(jia)零(ling)件(jian)后能完成多(duo)工序加(jia)工的數控機床(chuang)(即加(jia)工中心)方面發(fa)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)(jian)(批)試切完后，程序和相關生產(chan)信息可保留下(xia)(xia)來，下(xia)(xia)次(ci)(ci)產(chan)品再生產(chan)時(shi)，只要很少的(de)準備時(shi)間(jian)就可以開始生產(chan)。CNC加(jia)工中心工時(shi)包括準備工時(shi)和加(jia)工工時(shi)，CNC加(jia)工中心把(ba)很長的(de)單件(jian)(jian)準備工時(shi)平均(jun)分配到每一個工件(jian)(jian)上，使每次(ci)(ci)生產(chan)的(de)平均(jun)實際工時(shi)減少，生產(chan)周(zhou)期大大縮短。

        （2）高精度工(gong)(gong)(gong)(gong)件(jian):有些工(gong)(gong)(gong)(gong)件(jian)需求甚少(shao)，但(dan)屬關鍵部件(jian)，要(yao)求精度高且工(gong)(gong)(gong)(gong)期短，用傳統工(gong)(gong)(gong)(gong)藝需用多臺機床協調工(gong)(gong)(gong)(gong)作，其周期長、效率低，在長工(gong)(gong)(gong)(gong)序(xu)流(liu)程(cheng)(cheng)中(zhong)，受人為影響容易出廢品，從而造成重大經(jing)濟損失(shi)。而采用CNC加(jia)工(gong)(gong)(gong)(gong)中(zhong)心進行加(jia)工(gong)(gong)(gong)(gong),生(sheng)產完(wan)全由(you)程(cheng)(cheng)序(xu)自動控(kong)制.避免了長工(gong)(gong)(gong)(gong)序(xu)流(liu)程(cheng)(cheng),減少(shao)了硬件(jian)投資及(ji)人為干擾，具有生(sheng)產效益高及(ji)質量穩定的(de)特點。

        （3）批(pi)量(liang)(liang)生(sheng)(sheng)產(chan)的工(gong)(gong)(gong)件:CNC加(jia)工(gong)(gong)(gong)中(zhong)(zhong)心(xin)生(sheng)(sheng)產(chan)的柔(rou)性不僅體現(xian)在對特(te)殊要求的快速(su)反應(ying)上，而且(qie)可以(yi)(yi)快速(su)實現(xian)批(pi)量(liang)(liang)生(sheng)(sheng)產(chan)，以(yi)(yi)提高市場(chang)競爭能力。CNC加(jia)工(gong)(gong)(gong)中(zhong)(zhong)心(xin)適合于中(zhong)(zhong)小(xiao)批(pi)量(liang)(liang)生(sheng)(sheng)產(chan)，特(te)別是(shi)小(xiao)批(pi)量(liang)(liang)生(sheng)(sheng)產(chan)，在應(ying)用CNC加(jia)工(gong)(gong)(gong)中(zhong)(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)(yi)達到良(liang)好的經(jing)濟效果(guo)。隨著CNC加(jia)工(gong)(gong)(gong)中(zhong)(zhong)心(xin)的不斷發(fa)展(zhan)，經(jing)濟批(pi)量(liang)(liang)越來越小(xiao)，對一些(xie)復雜工(gong)(gong)(gong)件，5-10件就可以(yi)(yi)生(sheng)(sheng)產(chan)，甚至(zhi)單件生(sheng)(sheng)產(chan)時也可以(yi)(yi)考慮(lv)用CNC加(jia)工(gong)(gong)(gong)中(zhong)(zhong)心(xin)。
