  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)。加工(gong)中心是高度(du)機(ji)電(dian)一(yi)體化的產品，工(gong)件裝(zhuang)(zhuang)夾(jia)后(hou)，數(shu)控(kong)系統能控(kong)制機(ji)床(chuang)按不同工(gong)序(xu)(xu)自動(dong)選擇(ze)、更換刀(dao)具、自動(dong)對刀(dao)、自動(dong)改變(bian)主軸轉速、進給(gei)量(liang)等(deng)，可連續完成鉆、鏜、銑、鉸、攻絲等(deng)多種工(gong)序(xu)(xu)，因而大大減少了工(gong)件裝(zhuang)(zhuang)夾(jia)時間、測(ce)量(liang)和機(ji)床(chuang)調整等(deng)輔助工(gong)序(xu)(xu)時間，對加工(gong)形狀比較(jiao)復雜，精度(du)要求較(jiao)高，品種更換頻繁的零(ling)件具有良好的經濟(ji)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(le)進一步發(fa)揮這(zhe)些(xie)優點，數控機床(chuang)(chuang)遂向(xiang)“工(gong)序集中(zhong)”，即一臺數控機床(chuang)(chuang)在(zai)一次裝夾零件后能(neng)完(wan)成多工(gong)序加工(gong)的數控機床(chuang)(chuang)(即加工(gong)中(zhong)心)方(fang)面發(fa)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(shou)件(批)試切完(wan)后，程序和相關生產(chan)(chan)信息可保留下(xia)(xia)來，下(xia)(xia)次產(chan)(chan)品再生產(chan)(chan)時(shi)，只要(yao)很少的準(zhun)(zhun)備時(shi)間就可以開始(shi)生產(chan)(chan)。CNC加(jia)工(gong)(gong)中心工(gong)(gong)時(shi)包(bao)括準(zhun)(zhun)備工(gong)(gong)時(shi)和加(jia)工(gong)(gong)工(gong)(gong)時(shi)，CNC加(jia)工(gong)(gong)中心把很長(chang)的單件準(zhun)(zhun)備工(gong)(gong)時(shi)平均(jun)分(fen)配到每一個工(gong)(gong)件上，使每次生產(chan)(chan)的平均(jun)實際(ji)工(gong)(gong)時(shi)減少，生產(chan)(chan)周期大(da)大(da)縮(suo)短。

        （2）高(gao)精度工(gong)(gong)件:有(you)些工(gong)(gong)件需(xu)求(qiu)甚(shen)少(shao)，但(dan)屬關鍵部件，要(yao)求(qiu)精度高(gao)且工(gong)(gong)期短(duan)，用傳統(tong)工(gong)(gong)藝需(xu)用多(duo)臺機(ji)床協調工(gong)(gong)作，其周期長(chang)、效率(lv)低，在長(chang)工(gong)(gong)序(xu)(xu)流程中，受人為影響容(rong)易出(chu)廢品，從而造成重大(da)經(jing)濟(ji)損失。而采用CNC加(jia)工(gong)(gong)中心進(jin)行加(jia)工(gong)(gong),生(sheng)產(chan)完全由程序(xu)(xu)自動控(kong)制.避免了長(chang)工(gong)(gong)序(xu)(xu)流程,減少(shao)了硬件投資及人為干擾，具有(you)生(sheng)產(chan)效益高(gao)及質量(liang)穩(wen)定的(de)特點。

        （3）批(pi)量(liang)生(sheng)(sheng)產(chan)(chan)的(de)(de)工(gong)(gong)(gong)件:CNC加工(gong)(gong)(gong)中(zhong)(zhong)(zhong)心生(sheng)(sheng)產(chan)(chan)的(de)(de)柔性不(bu)僅體現(xian)在對(dui)特(te)殊(shu)要求(qiu)的(de)(de)快速反應上，而且可以快速實現(xian)批(pi)量(liang)生(sheng)(sheng)產(chan)(chan)，以提高市場競爭能力(li)。CNC加工(gong)(gong)(gong)中(zhong)(zhong)(zhong)心適合于中(zhong)(zhong)(zhong)小(xiao)批(pi)量(liang)生(sheng)(sheng)產(chan)(chan)，特(te)別是(shi)小(xiao)批(pi)量(liang)生(sheng)(sheng)產(chan)(chan)，在應用CNC加工(gong)(gong)(gong)中(zhong)(zhong)(zhong)心時(shi)。盡量(liang)使批(pi)量(liang)大(da)于經(jing)(jing)濟(ji)批(pi)量(liang),以達到良好的(de)(de)經(jing)(jing)濟(ji)效果。隨著(zhu)CNC加工(gong)(gong)(gong)中(zhong)(zhong)(zhong)心的(de)(de)不(bu)斷(duan)發展，經(jing)(jing)濟(ji)批(pi)量(liang)越來越小(xiao)，對(dui)一些復雜工(gong)(gong)(gong)件，5-10件就可以生(sheng)(sheng)產(chan)(chan)，甚至單件生(sheng)(sheng)產(chan)(chan)時(shi)也可以考慮(lv)用CNC加工(gong)(gong)(gong)中(zhong)(zhong)(zhong)心。
