  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)(jia)工(gong)(gong)中心是高(gao)度機(ji)電一體化的產品，工(gong)(gong)件裝夾后(hou)，數控系(xi)統能控制機(ji)床按不同工(gong)(gong)序(xu)自動選擇、更(geng)換(huan)刀(dao)具(ju)、自動對刀(dao)、自動改變主軸轉速、進給量(liang)等(deng)，可(ke)連續(xu)完(wan)成鉆、鏜、銑、鉸、攻絲(si)等(deng)多種(zhong)工(gong)(gong)序(xu)，因而大大減少了工(gong)(gong)件裝夾時間、測量(liang)和機(ji)床調整(zheng)等(deng)輔助工(gong)(gong)序(xu)時間，對加(jia)(jia)工(gong)(gong)形狀比較復雜，精度要求較高(gao)，品種(zhong)更(geng)換(huan)頻繁(fan)的零件具(ju)有良好的經濟(ji)效(xiao)果(guo)。

        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)步發揮這些優點，數控(kong)(kong)機床(chuang)(chuang)遂向“工(gong)序(xu)集中”，即一(yi)臺數控(kong)(kong)機床(chuang)(chuang)在一(yi)次(ci)裝夾零件(jian)后能完(wan)成多(duo)工(gong)序(xu)加工(gong)的(de)數控(kong)(kong)機床(chuang)(chuang)(即加工(gong)中心)方面發展(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，首件(批)試切完后，程序和(he)相關生(sheng)(sheng)產信息(xi)可(ke)保(bao)留下來，下次產品再生(sheng)(sheng)產時(shi)(shi)，只(zhi)要(yao)很(hen)少(shao)的(de)(de)準(zhun)備(bei)時(shi)(shi)間就可(ke)以開(kai)始(shi)生(sheng)(sheng)產。CNC加工(gong)(gong)中心(xin)工(gong)(gong)時(shi)(shi)包括準(zhun)備(bei)工(gong)(gong)時(shi)(shi)和(he)加工(gong)(gong)工(gong)(gong)時(shi)(shi)，CNC加工(gong)(gong)中心(xin)把很(hen)長的(de)(de)單件準(zhun)備(bei)工(gong)(gong)時(shi)(shi)平均分配到每(mei)一個(ge)工(gong)(gong)件上，使每(mei)次生(sheng)(sheng)產的(de)(de)平均實(shi)際工(gong)(gong)時(shi)(shi)減(jian)少(shao)，生(sheng)(sheng)產周期大大縮短。

        （2）高(gao)精(jing)度(du)工(gong)(gong)(gong)件(jian)(jian):有些工(gong)(gong)(gong)件(jian)(jian)需(xu)求(qiu)甚少，但屬關鍵部件(jian)(jian)，要求(qiu)精(jing)度(du)高(gao)且工(gong)(gong)(gong)期短，用(yong)(yong)傳統(tong)工(gong)(gong)(gong)藝需(xu)用(yong)(yong)多臺機床協調(diao)工(gong)(gong)(gong)作，其周期長(chang)(chang)、效率低，在(zai)長(chang)(chang)工(gong)(gong)(gong)序流程中(zhong)，受(shou)人為影響(xiang)容易出(chu)廢品(pin)，從而(er)(er)造成重(zhong)大經濟損失。而(er)(er)采用(yong)(yong)CNC加(jia)工(gong)(gong)(gong)中(zhong)心進行加(jia)工(gong)(gong)(gong),生產完全由(you)程序自動控制.避免了長(chang)(chang)工(gong)(gong)(gong)序流程,減少了硬件(jian)(jian)投資及(ji)人為干擾，具有生產效益高(gao)及(ji)質量穩定的特(te)點。

        （3）批(pi)(pi)量(liang)(liang)生(sheng)產的(de)工(gong)(gong)件:CNC加(jia)工(gong)(gong)中(zhong)心(xin)生(sheng)產的(de)柔性(xing)不(bu)僅體現在對(dui)特殊要求的(de)快速反應上(shang)，而且(qie)可(ke)以(yi)(yi)快速實現批(pi)(pi)量(liang)(liang)生(sheng)產，以(yi)(yi)提高市場競爭能力。CNC加(jia)工(gong)(gong)中(zhong)心(xin)適(shi)合于中(zhong)小批(pi)(pi)量(liang)(liang)生(sheng)產，特別是小批(pi)(pi)量(liang)(liang)生(sheng)產，在應用CNC加(jia)工(gong)(gong)中(zhong)心(xin)時(shi)(shi)。盡量(liang)(liang)使(shi)批(pi)(pi)量(liang)(liang)大于經濟(ji)批(pi)(pi)量(liang)(liang),以(yi)(yi)達(da)到良好的(de)經濟(ji)效(xiao)果(guo)。隨著CNC加(jia)工(gong)(gong)中(zhong)心(xin)的(de)不(bu)斷發展，經濟(ji)批(pi)(pi)量(liang)(liang)越(yue)來越(yue)小，對(dui)一些復雜(za)工(gong)(gong)件，5-10件就可(ke)以(yi)(yi)生(sheng)產，甚至單(dan)件生(sheng)產時(shi)(shi)也可(ke)以(yi)(yi)考(kao)慮用CNC加(jia)工(gong)(gong)中(zhong)心(xin)。
