  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(jia)工(gong)(gong)中心是高度機電(dian)一體化的(de)產品(pin)，工(gong)(gong)件裝夾(jia)后，數控系統能控制機床按(an)不同工(gong)(gong)序自(zi)(zi)動(dong)(dong)選擇、更換(huan)刀(dao)具、自(zi)(zi)動(dong)(dong)對刀(dao)、自(zi)(zi)動(dong)(dong)改變主(zhu)軸轉(zhuan)速、進(jin)給(gei)量(liang)等(deng)(deng)(deng)，可連續完成鉆、鏜(tang)、銑(xian)、鉸、攻絲等(deng)(deng)(deng)多種(zhong)(zhong)工(gong)(gong)序，因而(er)大大減少了工(gong)(gong)件裝夾(jia)時(shi)(shi)間(jian)、測量(liang)和機床調(diao)整(zheng)等(deng)(deng)(deng)輔(fu)助工(gong)(gong)序時(shi)(shi)間(jian)，對加(jia)工(gong)(gong)形狀比較復雜，精度要求(qiu)較高，品(pin)種(zhong)(zhong)更換(huan)頻(pin)繁的(de)零件具有良好的(de)經濟效(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(jia)為了進(jin)一(yi)步發揮這些(xie)優點，數(shu)控(kong)(kong)機床(chuang)(chuang)遂向“工(gong)(gong)序(xu)集中”，即(ji)(ji)一(yi)臺數(shu)控(kong)(kong)機床(chuang)(chuang)在一(yi)次(ci)裝夾(jia)零件后能完成多工(gong)(gong)序(xu)加(jia)工(gong)(gong)的數(shu)控(kong)(kong)機床(chuang)(chuang)(即(ji)(ji)加(jia)工(gong)(gong)中心)方面(mian)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(批)試切(qie)完后，程序和(he)相關(guan)生(sheng)(sheng)產信息(xi)可保留下來(lai)，下次(ci)產品再生(sheng)(sheng)產時(shi)，只要(yao)很少的(de)準備(bei)時(shi)間就可以開始生(sheng)(sheng)產。CNC加工(gong)(gong)中心工(gong)(gong)時(shi)包(bao)括(kuo)準備(bei)工(gong)(gong)時(shi)和(he)加工(gong)(gong)工(gong)(gong)時(shi)，CNC加工(gong)(gong)中心把很長的(de)單件準備(bei)工(gong)(gong)時(shi)平均分(fen)配到每一(yi)個工(gong)(gong)件上，使(shi)每次(ci)生(sheng)(sheng)產的(de)平均實際工(gong)(gong)時(shi)減少，生(sheng)(sheng)產周期大(da)大(da)縮短。

        （2）高精(jing)度(du)工(gong)件:有些(xie)工(gong)件需求甚少，但屬(shu)關鍵部件，要求精(jing)度(du)高且工(gong)期(qi)短，用(yong)(yong)傳統(tong)工(gong)藝(yi)需用(yong)(yong)多臺機(ji)床協(xie)調工(gong)作，其周(zhou)期(qi)長(chang)、效率低，在(zai)長(chang)工(gong)序流(liu)程(cheng)中(zhong)，受人為(wei)(wei)影響容易出廢(fei)品，從而造成(cheng)重(zhong)大經濟損(sun)失(shi)。而采用(yong)(yong)CNC加工(gong)中(zhong)心進行(xing)加工(gong),生(sheng)產完(wan)全(quan)由(you)程(cheng)序自動(dong)控制.避免了長(chang)工(gong)序流(liu)程(cheng),減少了硬件投資及人為(wei)(wei)干擾，具有生(sheng)產效益高及質量穩定的特點(dian)。

        （3）批(pi)(pi)(pi)(pi)(pi)量(liang)(liang)生(sheng)(sheng)產(chan)(chan)的(de)(de)工(gong)件(jian)(jian):CNC加工(gong)中(zhong)(zhong)心(xin)生(sheng)(sheng)產(chan)(chan)的(de)(de)柔性不(bu)僅體現在對特殊要求的(de)(de)快速(su)反應上，而(er)且(qie)可以快速(su)實現批(pi)(pi)(pi)(pi)(pi)量(liang)(liang)生(sheng)(sheng)產(chan)(chan)，以提高市場競爭(zheng)能力(li)。CNC加工(gong)中(zhong)(zhong)心(xin)適合于中(zhong)(zhong)小(xiao)批(pi)(pi)(pi)(pi)(pi)量(liang)(liang)生(sheng)(sheng)產(chan)(chan)，特別(bie)是(shi)小(xiao)批(pi)(pi)(pi)(pi)(pi)量(liang)(liang)生(sheng)(sheng)產(chan)(chan)，在應用CNC加工(gong)中(zhong)(zhong)心(xin)時(shi)。盡量(liang)(liang)使(shi)批(pi)(pi)(pi)(pi)(pi)量(liang)(liang)大于經濟批(pi)(pi)(pi)(pi)(pi)量(liang)(liang),以達(da)到良好的(de)(de)經濟效(xiao)果。隨著CNC加工(gong)中(zhong)(zhong)心(xin)的(de)(de)不(bu)斷發展，經濟批(pi)(pi)(pi)(pi)(pi)量(liang)(liang)越來(lai)越小(xiao)，對一(yi)些復雜工(gong)件(jian)(jian)，5-10件(jian)(jian)就可以生(sheng)(sheng)產(chan)(chan)，甚至單(dan)件(jian)(jian)生(sheng)(sheng)產(chan)(chan)時(shi)也可以考慮用CNC加工(gong)中(zhong)(zhong)心(xin)。
