  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(gao)度(du)機(ji)電(dian)一(yi)體化的(de)產品(pin)，工(gong)(gong)(gong)件裝(zhuang)夾后，數控(kong)(kong)系統能控(kong)(kong)制機(ji)床按不(bu)同工(gong)(gong)(gong)序自(zi)動(dong)(dong)選擇、更換刀(dao)具(ju)(ju)、自(zi)動(dong)(dong)對刀(dao)、自(zi)動(dong)(dong)改變主(zhu)軸轉速(su)、進給量等，可(ke)連續(xu)完成鉆、鏜、銑、鉸、攻(gong)絲等多種(zhong)工(gong)(gong)(gong)序，因(yin)而(er)大(da)(da)大(da)(da)減少了工(gong)(gong)(gong)件裝(zhuang)夾時間(jian)(jian)、測量和機(ji)床調整(zheng)等輔(fu)助工(gong)(gong)(gong)序時間(jian)(jian)，對加工(gong)(gong)(gong)形狀比較(jiao)復雜，精度(du)要(yao)求較(jiao)高(gao)，品(pin)種(zhong)更換頻繁的(de)零件具(ju)(ju)有(you)良好的(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零件加工中心廠家為了進一(yi)步(bu)發揮(hui)這些優點(dian)，數控機(ji)床(chuang)遂向“工(gong)序(xu)集中”，即(ji)一(yi)臺數控機(ji)床(chuang)在一(yi)次裝夾零件(jian)后(hou)能完成多工(gong)序(xu)加工(gong)的數控機(ji)床(chuang)(即(ji)加工(gong)中心(xin))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)試切完后(hou)，程序和相關生(sheng)(sheng)產(chan)信(xin)息(xi)可(ke)(ke)保留下(xia)(xia)來(lai)，下(xia)(xia)次產(chan)品再(zai)生(sheng)(sheng)產(chan)時(shi)(shi)，只要(yao)很少(shao)的(de)準(zhun)備時(shi)(shi)間(jian)就可(ke)(ke)以(yi)開始生(sheng)(sheng)產(chan)。CNC加(jia)工(gong)(gong)(gong)中心工(gong)(gong)(gong)時(shi)(shi)包括準(zhun)備工(gong)(gong)(gong)時(shi)(shi)和加(jia)工(gong)(gong)(gong)工(gong)(gong)(gong)時(shi)(shi)，CNC加(jia)工(gong)(gong)(gong)中心把很長的(de)單(dan)件準(zhun)備工(gong)(gong)(gong)時(shi)(shi)平均(jun)分配到(dao)每一個工(gong)(gong)(gong)件上，使(shi)每次生(sheng)(sheng)產(chan)的(de)平均(jun)實(shi)際(ji)工(gong)(gong)(gong)時(shi)(shi)減少(shao)，生(sheng)(sheng)產(chan)周(zhou)期大大縮短。

        （2）高(gao)(gao)精度工(gong)件(jian):有(you)些工(gong)件(jian)需求甚少，但屬關(guan)鍵部(bu)件(jian)，要求精度高(gao)(gao)且工(gong)期短(duan)，用(yong)傳(chuan)統工(gong)藝需用(yong)多臺機(ji)床協(xie)調工(gong)作，其周期長(chang)、效率低，在長(chang)工(gong)序流(liu)程(cheng)中(zhong)，受人(ren)為(wei)影(ying)響容易出廢品(pin)，從而造成(cheng)重(zhong)大經濟(ji)損失。而采用(yong)CNC加工(gong)中(zhong)心進(jin)行加工(gong),生(sheng)產完全由程(cheng)序自(zi)動控(kong)制.避(bi)免了長(chang)工(gong)序流(liu)程(cheng),減少了硬(ying)件(jian)投(tou)資(zi)及人(ren)為(wei)干(gan)擾，具(ju)有(you)生(sheng)產效益高(gao)(gao)及質量穩(wen)定的特點。

        （3）批(pi)量(liang)(liang)(liang)(liang)(liang)生(sheng)產(chan)的(de)工(gong)(gong)件:CNC加工(gong)(gong)中(zhong)心生(sheng)產(chan)的(de)柔性不僅體現在(zai)對特殊要求的(de)快速反(fan)應(ying)(ying)上(shang)，而(er)且可(ke)(ke)以快速實現批(pi)量(liang)(liang)(liang)(liang)(liang)生(sheng)產(chan)，以提高市場競爭能力。CNC加工(gong)(gong)中(zhong)心適合于中(zhong)小批(pi)量(liang)(liang)(liang)(liang)(liang)生(sheng)產(chan)，特別(bie)是(shi)小批(pi)量(liang)(liang)(liang)(liang)(liang)生(sheng)產(chan)，在(zai)應(ying)(ying)用CNC加工(gong)(gong)中(zhong)心時。盡量(liang)(liang)(liang)(liang)(liang)使批(pi)量(liang)(liang)(liang)(liang)(liang)大于經濟(ji)批(pi)量(liang)(liang)(liang)(liang)(liang),以達到良(liang)好的(de)經濟(ji)效果。隨著(zhu)CNC加工(gong)(gong)中(zhong)心的(de)不斷發展，經濟(ji)批(pi)量(liang)(liang)(liang)(liang)(liang)越來(lai)越小，對一些復雜工(gong)(gong)件，5-10件就可(ke)(ke)以生(sheng)產(chan)，甚至(zhi)單(dan)件生(sheng)產(chan)時也可(ke)(ke)以考慮用CNC加工(gong)(gong)中(zhong)心。
