  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)(chuang)。加工(gong)(gong)(gong)中心(xin)是高(gao)度(du)機電一體化的(de)(de)產品(pin)，工(gong)(gong)(gong)件(jian)裝夾后，數控系統能控制機床(chuang)(chuang)按不同(tong)工(gong)(gong)(gong)序自動(dong)選擇、更(geng)換刀(dao)具、自動(dong)對刀(dao)、自動(dong)改(gai)變主軸轉速、進給(gei)量等，可(ke)連續完成鉆(zhan)、鏜、銑(xian)、鉸、攻(gong)絲(si)等多種(zhong)工(gong)(gong)(gong)序，因而(er)大大減少了工(gong)(gong)(gong)件(jian)裝夾時(shi)間、測量和機床(chuang)(chuang)調整等輔助(zhu)工(gong)(gong)(gong)序時(shi)間，對加工(gong)(gong)(gong)形(xing)狀比(bi)較復(fu)雜，精度(du)要(yao)求較高(gao)，品(pin)種(zhong)更(geng)換頻繁的(de)(de)零件(jian)具有良好的(de)(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零件加工中心廠家為了進一步發(fa)揮(hui)這些優點，數(shu)控(kong)機床(chuang)遂向“工(gong)序集中”，即一臺數(shu)控(kong)機床(chuang)在一次(ci)裝(zhuang)夾零件(jian)后能完成(cheng)多工(gong)序加工(gong)的數(shu)控(kong)機床(chuang)(即加工(gong)中心(xin))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)(批)試切完后，程序和(he)相關生(sheng)(sheng)產(chan)信息可保留下來，下次產(chan)品再生(sheng)(sheng)產(chan)時(shi)(shi)，只要很少(shao)的(de)(de)(de)準(zhun)備(bei)(bei)時(shi)(shi)間(jian)就可以開始生(sheng)(sheng)產(chan)。CNC加工(gong)中心工(gong)時(shi)(shi)包括準(zhun)備(bei)(bei)工(gong)時(shi)(shi)和(he)加工(gong)工(gong)時(shi)(shi)，CNC加工(gong)中心把(ba)很長的(de)(de)(de)單(dan)件(jian)準(zhun)備(bei)(bei)工(gong)時(shi)(shi)平均(jun)分配(pei)到每一(yi)個工(gong)件(jian)上，使每次生(sheng)(sheng)產(chan)的(de)(de)(de)平均(jun)實際工(gong)時(shi)(shi)減(jian)少(shao)，生(sheng)(sheng)產(chan)周期大大縮短(duan)。

        （2）高精度工(gong)(gong)(gong)(gong)(gong)(gong)件:有(you)些工(gong)(gong)(gong)(gong)(gong)(gong)件需(xu)求甚少，但屬關鍵(jian)部件，要求精度高且工(gong)(gong)(gong)(gong)(gong)(gong)期短(duan)，用傳統工(gong)(gong)(gong)(gong)(gong)(gong)藝需(xu)用多臺機床協調工(gong)(gong)(gong)(gong)(gong)(gong)作(zuo)，其周期長、效(xiao)率低，在長工(gong)(gong)(gong)(gong)(gong)(gong)序(xu)流程中(zhong)，受人(ren)為影響(xiang)容易出廢(fei)品，從而(er)造成重(zhong)大經濟損失(shi)。而(er)采用CNC加工(gong)(gong)(gong)(gong)(gong)(gong)中(zhong)心進行加工(gong)(gong)(gong)(gong)(gong)(gong),生(sheng)產完全由程序(xu)自動控(kong)制.避免了長工(gong)(gong)(gong)(gong)(gong)(gong)序(xu)流程,減(jian)少了硬(ying)件投(tou)資及人(ren)為干擾，具有(you)生(sheng)產效(xiao)益高及質量穩定(ding)的特點。

        （3）批量(liang)(liang)(liang)生(sheng)(sheng)(sheng)產(chan)(chan)(chan)的(de)工(gong)件(jian):CNC加(jia)工(gong)中心(xin)生(sheng)(sheng)(sheng)產(chan)(chan)(chan)的(de)柔性不僅體現(xian)在對(dui)特殊(shu)要求的(de)快速(su)反應(ying)(ying)上(shang)，而且可(ke)(ke)以(yi)快速(su)實現(xian)批量(liang)(liang)(liang)生(sheng)(sheng)(sheng)產(chan)(chan)(chan)，以(yi)提高市場競爭能力。CNC加(jia)工(gong)中心(xin)適(shi)合于中小批量(liang)(liang)(liang)生(sheng)(sheng)(sheng)產(chan)(chan)(chan)，特別是小批量(liang)(liang)(liang)生(sheng)(sheng)(sheng)產(chan)(chan)(chan)，在應(ying)(ying)用CNC加(jia)工(gong)中心(xin)時。盡(jin)量(liang)(liang)(liang)使批量(liang)(liang)(liang)大于經(jing)濟批量(liang)(liang)(liang),以(yi)達到(dao)良好的(de)經(jing)濟效果。隨(sui)著CNC加(jia)工(gong)中心(xin)的(de)不斷發展，經(jing)濟批量(liang)(liang)(liang)越來越小，對(dui)一(yi)些復雜(za)工(gong)件(jian)，5-10件(jian)就(jiu)可(ke)(ke)以(yi)生(sheng)(sheng)(sheng)產(chan)(chan)(chan)，甚至單件(jian)生(sheng)(sheng)(sheng)產(chan)(chan)(chan)時也(ye)可(ke)(ke)以(yi)考慮用CNC加(jia)工(gong)中心(xin)。
