  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)中心是高度機(ji)電一體化的(de)(de)產品，工(gong)(gong)(gong)件(jian)裝(zhuang)夾后，數控(kong)系統能控(kong)制機(ji)床按(an)不同工(gong)(gong)(gong)序(xu)自動選擇、更換刀具、自動對刀、自動改變主軸(zhou)轉速、進(jin)給(gei)量(liang)等(deng)(deng)，可連(lian)續完成鉆、鏜、銑、鉸、攻(gong)絲等(deng)(deng)多種工(gong)(gong)(gong)序(xu)，因(yin)而大大減少(shao)了工(gong)(gong)(gong)件(jian)裝(zhuang)夾時(shi)間(jian)、測量(liang)和機(ji)床調整等(deng)(deng)輔助工(gong)(gong)(gong)序(xu)時(shi)間(jian)，對加工(gong)(gong)(gong)形狀(zhuang)比(bi)較(jiao)復雜，精度要求較(jiao)高，品種更換頻繁的(de)(de)零件(jian)具有(you)良好的(de)(de)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一步發揮這些優點，數控(kong)機(ji)床遂(sui)向“工序(xu)集(ji)中(zhong)”，即一臺數控(kong)機(ji)床在(zai)一次裝夾零件后能完(wan)成多工序(xu)加工的數控(kong)機(ji)床(即加工中(zhong)心(xin))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(shou)件(批)試切完后(hou)，程序和相關(guan)生(sheng)(sheng)產(chan)(chan)(chan)(chan)信息可保(bao)留下來，下次(ci)產(chan)(chan)(chan)(chan)品再生(sheng)(sheng)產(chan)(chan)(chan)(chan)時，只要很少的(de)準備時間就可以開始生(sheng)(sheng)產(chan)(chan)(chan)(chan)。CNC加(jia)(jia)工(gong)(gong)中心(xin)工(gong)(gong)時包括(kuo)準備工(gong)(gong)時和加(jia)(jia)工(gong)(gong)工(gong)(gong)時，CNC加(jia)(jia)工(gong)(gong)中心(xin)把很長(chang)的(de)單件準備工(gong)(gong)時平均分配到每一(yi)個工(gong)(gong)件上(shang)，使每次(ci)生(sheng)(sheng)產(chan)(chan)(chan)(chan)的(de)平均實際工(gong)(gong)時減少，生(sheng)(sheng)產(chan)(chan)(chan)(chan)周期大大縮(suo)短。

        （2）高(gao)精度工(gong)(gong)(gong)件:有些工(gong)(gong)(gong)件需求甚少(shao)，但屬(shu)關鍵部件，要求精度高(gao)且工(gong)(gong)(gong)期短，用傳統工(gong)(gong)(gong)藝需用多(duo)臺機床協調(diao)工(gong)(gong)(gong)作(zuo)，其(qi)周期長(chang)(chang)(chang)、效率低，在長(chang)(chang)(chang)工(gong)(gong)(gong)序流(liu)程中(zhong)，受人為影響容易出廢品，從而造成重(zhong)大經(jing)濟損失。而采用CNC加工(gong)(gong)(gong)中(zhong)心進行加工(gong)(gong)(gong),生產(chan)完全由程序自動控(kong)制.避(bi)免了(le)長(chang)(chang)(chang)工(gong)(gong)(gong)序流(liu)程,減少(shao)了(le)硬(ying)件投資(zi)及人為干擾，具有生產(chan)效益(yi)高(gao)及質量穩定的(de)特點。

        （3）批(pi)(pi)量(liang)(liang)(liang)生產(chan)(chan)的(de)工(gong)(gong)件:CNC加(jia)工(gong)(gong)中(zhong)(zhong)(zhong)(zhong)心生產(chan)(chan)的(de)柔性不(bu)僅體現在(zai)對特殊要(yao)求(qiu)的(de)快(kuai)速(su)反應(ying)上，而且可以(yi)快(kuai)速(su)實(shi)現批(pi)(pi)量(liang)(liang)(liang)生產(chan)(chan)，以(yi)提高市場競爭(zheng)能力(li)。CNC加(jia)工(gong)(gong)中(zhong)(zhong)(zhong)(zhong)心適合于(yu)中(zhong)(zhong)(zhong)(zhong)小批(pi)(pi)量(liang)(liang)(liang)生產(chan)(chan)，特別是小批(pi)(pi)量(liang)(liang)(liang)生產(chan)(chan)，在(zai)應(ying)用(yong)CNC加(jia)工(gong)(gong)中(zhong)(zhong)(zhong)(zhong)心時。盡(jin)量(liang)(liang)(liang)使(shi)批(pi)(pi)量(liang)(liang)(liang)大于(yu)經濟批(pi)(pi)量(liang)(liang)(liang),以(yi)達(da)到良好的(de)經濟效果(guo)。隨著CNC加(jia)工(gong)(gong)中(zhong)(zhong)(zhong)(zhong)心的(de)不(bu)斷發展，經濟批(pi)(pi)量(liang)(liang)(liang)越(yue)來越(yue)小，對一(yi)些復(fu)雜工(gong)(gong)件，5-10件就可以(yi)生產(chan)(chan)，甚至(zhi)單件生產(chan)(chan)時也可以(yi)考(kao)慮用(yong)CNC加(jia)工(gong)(gong)中(zhong)(zhong)(zhong)(zhong)心。
