  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)(gong)中心(xin)是(shi)高度機電一體化的產品(pin)，工(gong)(gong)(gong)件(jian)(jian)裝(zhuang)夾(jia)后(hou)，數控(kong)(kong)系統(tong)能控(kong)(kong)制機床按不同工(gong)(gong)(gong)序(xu)自(zi)動選擇、更換(huan)刀具(ju)、自(zi)動對刀、自(zi)動改變主軸轉速、進給量(liang)(liang)等(deng)，可(ke)連續完成(cheng)鉆、鏜、銑、鉸、攻絲等(deng)多(duo)種(zhong)(zhong)工(gong)(gong)(gong)序(xu)，因而(er)大大減少了工(gong)(gong)(gong)件(jian)(jian)裝(zhuang)夾(jia)時間、測(ce)量(liang)(liang)和機床調整等(deng)輔助工(gong)(gong)(gong)序(xu)時間，對加(jia)工(gong)(gong)(gong)形狀比較(jiao)復雜，精度要求(qiu)較(jiao)高，品(pin)種(zhong)(zhong)更換(huan)頻繁的零件(jian)(jian)具(ju)有良好的經濟效(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零件加工中心廠家為了進(jin)一(yi)步(bu)發(fa)揮(hui)這些優點，數控(kong)(kong)機床遂向“工序(xu)集中(zhong)”，即(ji)(ji)一(yi)臺數控(kong)(kong)機床在一(yi)次(ci)裝夾零件后能完成(cheng)多工序(xu)加工的數控(kong)(kong)機床(即(ji)(ji)加工中(zhong)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(shou)件(批)試切完后，程序(xu)和(he)相關生(sheng)(sheng)產(chan)信息可保(bao)留下(xia)來，下(xia)次(ci)產(chan)品(pin)再生(sheng)(sheng)產(chan)時(shi)，只要很(hen)少(shao)的準備(bei)時(shi)間就可以開始生(sheng)(sheng)產(chan)。CNC加工(gong)(gong)中心工(gong)(gong)時(shi)包括(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(hen)長的單件準備(bei)工(gong)(gong)時(shi)平均分配到每一個工(gong)(gong)件上，使每次(ci)生(sheng)(sheng)產(chan)的平均實(shi)際工(gong)(gong)時(shi)減(jian)少(shao)，生(sheng)(sheng)產(chan)周期(qi)大大縮短。

        （2）高(gao)精度工(gong)(gong)(gong)件(jian):有(you)些工(gong)(gong)(gong)件(jian)需求(qiu)甚少(shao)，但屬關鍵部件(jian)，要求(qiu)精度高(gao)且工(gong)(gong)(gong)期(qi)短，用(yong)傳(chuan)統工(gong)(gong)(gong)藝需用(yong)多臺機床協調工(gong)(gong)(gong)作，其周期(qi)長(chang)、效(xiao)率(lv)低，在(zai)長(chang)工(gong)(gong)(gong)序流(liu)程(cheng)中，受人為影(ying)響容易出廢品(pin)，從(cong)而(er)造成(cheng)重大經濟(ji)損失。而(er)采(cai)用(yong)CNC加工(gong)(gong)(gong)中心進行加工(gong)(gong)(gong),生(sheng)(sheng)產完(wan)全由程(cheng)序自(zi)動(dong)控(kong)制.避(bi)免了長(chang)工(gong)(gong)(gong)序流(liu)程(cheng),減少(shao)了硬件(jian)投資及人為干擾(rao)，具(ju)有(you)生(sheng)(sheng)產效(xiao)益(yi)高(gao)及質量穩定的(de)特點。

        （3）批(pi)(pi)量生(sheng)(sheng)產(chan)(chan)(chan)的(de)工(gong)件(jian):CNC加(jia)(jia)工(gong)中(zhong)心(xin)(xin)生(sheng)(sheng)產(chan)(chan)(chan)的(de)柔性不僅(jin)體現在(zai)對(dui)特殊(shu)要求的(de)快速反(fan)應上，而且可(ke)以(yi)快速實(shi)現批(pi)(pi)量生(sheng)(sheng)產(chan)(chan)(chan)，以(yi)提高市場競爭(zheng)能力。CNC加(jia)(jia)工(gong)中(zhong)心(xin)(xin)適合于(yu)中(zhong)小批(pi)(pi)量生(sheng)(sheng)產(chan)(chan)(chan)，特別(bie)是(shi)小批(pi)(pi)量生(sheng)(sheng)產(chan)(chan)(chan)，在(zai)應用CNC加(jia)(jia)工(gong)中(zhong)心(xin)(xin)時。盡量使批(pi)(pi)量大(da)于(yu)經濟(ji)批(pi)(pi)量,以(yi)達到良(liang)好的(de)經濟(ji)效果。隨著CNC加(jia)(jia)工(gong)中(zhong)心(xin)(xin)的(de)不斷(duan)發展(zhan)，經濟(ji)批(pi)(pi)量越來(lai)越小，對(dui)一(yi)些復雜(za)工(gong)件(jian)，5-10件(jian)就可(ke)以(yi)生(sheng)(sheng)產(chan)(chan)(chan)，甚至(zhi)單件(jian)生(sheng)(sheng)產(chan)(chan)(chan)時也可(ke)以(yi)考(kao)慮用CNC加(jia)(jia)工(gong)中(zhong)心(xin)(xin)。
