  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(zhong)心是高(gao)(gao)度機(ji)電一體化的產品(pin)，工(gong)(gong)(gong)件裝(zhuang)夾(jia)后，數控系統能控制機(ji)床(chuang)(chuang)按不(bu)同工(gong)(gong)(gong)序自(zi)動(dong)選擇、更換(huan)刀(dao)具、自(zi)動(dong)對(dui)刀(dao)、自(zi)動(dong)改變主軸轉速、進給量(liang)等(deng)，可連續(xu)完成鉆、鏜、銑、鉸、攻絲等(deng)多(duo)種工(gong)(gong)(gong)序，因而大(da)大(da)減少了(le)工(gong)(gong)(gong)件裝(zhuang)夾(jia)時間(jian)、測量(liang)和(he)機(ji)床(chuang)(chuang)調整(zheng)等(deng)輔助工(gong)(gong)(gong)序時間(jian)，對(dui)加工(gong)(gong)(gong)形狀比較(jiao)復雜，精度要求較(jiao)高(gao)(gao)，品(pin)種更換(huan)頻繁的零件具有良好(hao)的經濟效果。

        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(bu)發(fa)揮(hui)這些優點，數控機(ji)床遂向“工序集中”，即(ji)(ji)一臺數控機(ji)床在(zai)一次裝夾(jia)零件后(hou)能完成(cheng)多工序加(jia)工的數控機(ji)床(即(ji)(ji)加(jia)工中心)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(批)試切完后，程(cheng)序和相關生產信息可保留下來(lai)，下次產品再生產時(shi)，只要很(hen)少(shao)的準備時(shi)間就可以開始(shi)生產。CNC加(jia)(jia)工(gong)(gong)(gong)中(zhong)心(xin)工(gong)(gong)(gong)時(shi)包括準備工(gong)(gong)(gong)時(shi)和加(jia)(jia)工(gong)(gong)(gong)工(gong)(gong)(gong)時(shi)，CNC加(jia)(jia)工(gong)(gong)(gong)中(zhong)心(xin)把很(hen)長的單件準備工(gong)(gong)(gong)時(shi)平均分配到每(mei)一個工(gong)(gong)(gong)件上，使每(mei)次生產的平均實際(ji)工(gong)(gong)(gong)時(shi)減(jian)少(shao)，生產周期(qi)大(da)大(da)縮(suo)短。

        （2）高(gao)精度(du)工件(jian):有些工件(jian)需求甚少(shao)，但(dan)屬關鍵部件(jian)，要求精度(du)高(gao)且工期短(duan)，用傳統工藝需用多(duo)臺機床協調(diao)工作，其周期長、效(xiao)率(lv)低，在長工序(xu)流程中，受人為(wei)影響容易出廢(fei)品，從而造成重(zhong)大經濟損失。而采用CNC加工中心(xin)進(jin)行(xing)加工,生產完全由程序(xu)自動控制(zhi).避免(mian)了(le)長工序(xu)流程,減少(shao)了(le)硬件(jian)投資及人為(wei)干(gan)擾，具有生產效(xiao)益高(gao)及質量穩定的特點。

        （3）批(pi)量(liang)(liang)(liang)(liang)生(sheng)(sheng)(sheng)產(chan)(chan)(chan)的工(gong)(gong)件(jian):CNC加(jia)(jia)工(gong)(gong)中(zhong)(zhong)心生(sheng)(sheng)(sheng)產(chan)(chan)(chan)的柔性不僅體現在對特殊要求的快速(su)反應上，而且可以快速(su)實現批(pi)量(liang)(liang)(liang)(liang)生(sheng)(sheng)(sheng)產(chan)(chan)(chan)，以提高市場競(jing)爭能力。CNC加(jia)(jia)工(gong)(gong)中(zhong)(zhong)心適合于(yu)中(zhong)(zhong)小批(pi)量(liang)(liang)(liang)(liang)生(sheng)(sheng)(sheng)產(chan)(chan)(chan)，特別是(shi)小批(pi)量(liang)(liang)(liang)(liang)生(sheng)(sheng)(sheng)產(chan)(chan)(chan)，在應用(yong)CNC加(jia)(jia)工(gong)(gong)中(zhong)(zhong)心時。盡量(liang)(liang)(liang)(liang)使批(pi)量(liang)(liang)(liang)(liang)大(da)于(yu)經(jing)濟(ji)批(pi)量(liang)(liang)(liang)(liang),以達到(dao)良好的經(jing)濟(ji)效(xiao)果。隨著(zhu)CNC加(jia)(jia)工(gong)(gong)中(zhong)(zhong)心的不斷發(fa)展，經(jing)濟(ji)批(pi)量(liang)(liang)(liang)(liang)越(yue)來越(yue)小，對一些復雜工(gong)(gong)件(jian)，5-10件(jian)就可以生(sheng)(sheng)(sheng)產(chan)(chan)(chan)，甚(shen)至(zhi)單件(jian)生(sheng)(sheng)(sheng)產(chan)(chan)(chan)時也(ye)可以考慮用(yong)CNC加(jia)(jia)工(gong)(gong)中(zhong)(zhong)心。
