  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(du)機(ji)(ji)電一體化的(de)產品(pin)，工(gong)(gong)(gong)件(jian)裝(zhuang)夾后，數控(kong)系統能(neng)控(kong)制機(ji)(ji)床按不同工(gong)(gong)(gong)序(xu)自動選(xuan)擇、更換刀(dao)具(ju)、自動對刀(dao)、自動改變主(zhu)軸轉速、進給(gei)量等，可連續完成鉆、鏜、銑、鉸、攻絲(si)等多種(zhong)工(gong)(gong)(gong)序(xu)，因(yin)而大(da)大(da)減少了工(gong)(gong)(gong)件(jian)裝(zhuang)夾時(shi)間、測量和(he)機(ji)(ji)床調(diao)整(zheng)等輔助工(gong)(gong)(gong)序(xu)時(shi)間，對加工(gong)(gong)(gong)形狀比較(jiao)復(fu)雜，精度(du)要求較(jiao)高，品(pin)種(zhong)更換頻繁的(de)零(ling)件(jian)具(ju)有(you)良(liang)好的(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(jia)為了進一(yi)步(bu)發揮這(zhe)些優點，數控(kong)(kong)機床遂向(xiang)“工序(xu)集中”，即一(yi)臺數控(kong)(kong)機床在一(yi)次裝夾零(ling)件后能完成多工序(xu)加工的數控(kong)(kong)機床(即加工中心)方面發展。

        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(jian)(jian)(批(pi))試(shi)切完后，程(cheng)序和相關生(sheng)產信息可(ke)保留(liu)下(xia)來，下(xia)次產品再生(sheng)產時，只要很少的準(zhun)備(bei)時間就可(ke)以開始生(sheng)產。CNC加工(gong)(gong)中(zhong)心(xin)(xin)工(gong)(gong)時包括(kuo)準(zhun)備(bei)工(gong)(gong)時和加工(gong)(gong)工(gong)(gong)時，CNC加工(gong)(gong)中(zhong)心(xin)(xin)把(ba)很長的單件(jian)(jian)準(zhun)備(bei)工(gong)(gong)時平均(jun)分配到每(mei)一個工(gong)(gong)件(jian)(jian)上，使每(mei)次生(sheng)產的平均(jun)實際(ji)工(gong)(gong)時減少，生(sheng)產周期大(da)大(da)縮(suo)短。

        （2）高(gao)(gao)精度工(gong)(gong)(gong)件(jian):有些工(gong)(gong)(gong)件(jian)需求甚少(shao)(shao)，但(dan)屬關鍵部件(jian)，要求精度高(gao)(gao)且工(gong)(gong)(gong)期(qi)短，用(yong)(yong)傳統工(gong)(gong)(gong)藝需用(yong)(yong)多臺機床協(xie)調工(gong)(gong)(gong)作，其周期(qi)長、效率(lv)低，在(zai)長工(gong)(gong)(gong)序流程中，受人為(wei)影響(xiang)容(rong)易出廢品(pin)，從而造成(cheng)重(zhong)大經(jing)濟(ji)損失。而采用(yong)(yong)CNC加工(gong)(gong)(gong)中心(xin)進(jin)行(xing)加工(gong)(gong)(gong),生(sheng)產(chan)完全由程序自(zi)動控制.避(bi)免了(le)長工(gong)(gong)(gong)序流程,減少(shao)(shao)了(le)硬件(jian)投資及(ji)人為(wei)干擾(rao)，具(ju)有生(sheng)產(chan)效益高(gao)(gao)及(ji)質量(liang)穩定的特(te)點(dian)。

        （3）批(pi)(pi)(pi)量(liang)(liang)(liang)(liang)生(sheng)(sheng)產(chan)的工件(jian)(jian):CNC加(jia)工中(zhong)(zhong)心(xin)(xin)生(sheng)(sheng)產(chan)的柔性不僅體現在對特殊(shu)要(yao)求的快速反應(ying)上，而且可(ke)以(yi)快速實現批(pi)(pi)(pi)量(liang)(liang)(liang)(liang)生(sheng)(sheng)產(chan)，以(yi)提高市場競(jing)爭能力(li)。CNC加(jia)工中(zhong)(zhong)心(xin)(xin)適合于中(zhong)(zhong)小批(pi)(pi)(pi)量(liang)(liang)(liang)(liang)生(sheng)(sheng)產(chan)，特別是(shi)小批(pi)(pi)(pi)量(liang)(liang)(liang)(liang)生(sheng)(sheng)產(chan)，在應(ying)用(yong)(yong)CNC加(jia)工中(zhong)(zhong)心(xin)(xin)時(shi)。盡量(liang)(liang)(liang)(liang)使批(pi)(pi)(pi)量(liang)(liang)(liang)(liang)大于經(jing)濟(ji)批(pi)(pi)(pi)量(liang)(liang)(liang)(liang),以(yi)達到良好的經(jing)濟(ji)效果(guo)。隨著(zhu)CNC加(jia)工中(zhong)(zhong)心(xin)(xin)的不斷(duan)發展，經(jing)濟(ji)批(pi)(pi)(pi)量(liang)(liang)(liang)(liang)越來越小，對一些(xie)復雜工件(jian)(jian)，5-10件(jian)(jian)就可(ke)以(yi)生(sheng)(sheng)產(chan)，甚至單(dan)件(jian)(jian)生(sheng)(sheng)產(chan)時(shi)也(ye)可(ke)以(yi)考(kao)慮用(yong)(yong)CNC加(jia)工中(zhong)(zhong)心(xin)(xin)。
