  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)中(zhong)心是(shi)高(gao)度機電一體化(hua)的(de)(de)產(chan)品(pin)，工(gong)件(jian)(jian)(jian)裝夾(jia)后，數控系統能控制(zhi)機床按不同工(gong)序(xu)(xu)自動選擇、更換刀具、自動對刀、自動改變主軸轉速(su)、進給量等(deng)，可連續完成鉆、鏜、銑、鉸、攻(gong)絲等(deng)多種工(gong)序(xu)(xu)，因(yin)而大大減少了工(gong)件(jian)(jian)(jian)裝夾(jia)時間、測量和機床調整等(deng)輔(fu)助工(gong)序(xu)(xu)時間，對加工(gong)形(xing)狀比較(jiao)復(fu)雜，精度要求較(jiao)高(gao)，品(pin)種更換頻繁的(de)(de)零件(jian)(jian)(jian)具有良好(hao)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(jin)一(yi)步發揮這(zhe)些(xie)優點，數(shu)控機床遂(sui)向“工(gong)(gong)序(xu)集中”，即一(yi)臺數(shu)控機床在(zai)一(yi)次裝夾零件后能完成(cheng)多工(gong)(gong)序(xu)加工(gong)(gong)的數(shu)控機床(即加工(gong)(gong)中心)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，首件(jian)(批(pi))試切(qie)完后(hou)，程序和(he)相關生產(chan)信息可保留下(xia)來(lai)，下(xia)次(ci)產(chan)品再生產(chan)時(shi)，只要很(hen)少的準(zhun)備(bei)時(shi)間(jian)就可以開始(shi)生產(chan)。CNC加(jia)工(gong)(gong)中心(xin)(xin)工(gong)(gong)時(shi)包括準(zhun)備(bei)工(gong)(gong)時(shi)和(he)加(jia)工(gong)(gong)工(gong)(gong)時(shi)，CNC加(jia)工(gong)(gong)中心(xin)(xin)把很(hen)長的單件(jian)準(zhun)備(bei)工(gong)(gong)時(shi)平均分配(pei)到每一個工(gong)(gong)件(jian)上(shang)，使每次(ci)生產(chan)的平均實際工(gong)(gong)時(shi)減少，生產(chan)周期大(da)大(da)縮(suo)短。

        （2）高(gao)精度(du)工(gong)(gong)(gong)(gong)件(jian)(jian):有些(xie)工(gong)(gong)(gong)(gong)件(jian)(jian)需(xu)(xu)求(qiu)甚少，但(dan)屬關鍵部件(jian)(jian)，要求(qiu)精度(du)高(gao)且工(gong)(gong)(gong)(gong)期(qi)短，用傳統工(gong)(gong)(gong)(gong)藝需(xu)(xu)用多臺機床協調(diao)工(gong)(gong)(gong)(gong)作，其周期(qi)長、效率低，在長工(gong)(gong)(gong)(gong)序(xu)流程中(zhong)，受人為影響容易出廢品，從而造成重(zhong)大經濟損失。而采(cai)用CNC加(jia)工(gong)(gong)(gong)(gong)中(zhong)心進行加(jia)工(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)序(xu)流程,減(jian)少了硬件(jian)(jian)投資及人為干(gan)擾，具有生(sheng)產效益高(gao)及質(zhi)量穩定的特(te)點。

        （3）批(pi)(pi)量生(sheng)產(chan)(chan)(chan)(chan)的工(gong)(gong)(gong)件(jian):CNC加工(gong)(gong)(gong)中(zhong)(zhong)(zhong)心(xin)(xin)生(sheng)產(chan)(chan)(chan)(chan)的柔性不(bu)僅(jin)體現(xian)在對(dui)特(te)殊要求的快(kuai)速反應(ying)上，而且可以(yi)(yi)快(kuai)速實現(xian)批(pi)(pi)量生(sheng)產(chan)(chan)(chan)(chan)，以(yi)(yi)提高市場競爭能力(li)。CNC加工(gong)(gong)(gong)中(zhong)(zhong)(zhong)心(xin)(xin)適合(he)于(yu)(yu)中(zhong)(zhong)(zhong)小批(pi)(pi)量生(sheng)產(chan)(chan)(chan)(chan)，特(te)別是(shi)小批(pi)(pi)量生(sheng)產(chan)(chan)(chan)(chan)，在應(ying)用CNC加工(gong)(gong)(gong)中(zhong)(zhong)(zhong)心(xin)(xin)時(shi)。盡量使(shi)批(pi)(pi)量大于(yu)(yu)經(jing)(jing)濟批(pi)(pi)量,以(yi)(yi)達到(dao)良好(hao)的經(jing)(jing)濟效果(guo)。隨(sui)著(zhu)CNC加工(gong)(gong)(gong)中(zhong)(zhong)(zhong)心(xin)(xin)的不(bu)斷發展(zhan)，經(jing)(jing)濟批(pi)(pi)量越(yue)來(lai)越(yue)小，對(dui)一些復(fu)雜(za)工(gong)(gong)(gong)件(jian)，5-10件(jian)就(jiu)可以(yi)(yi)生(sheng)產(chan)(chan)(chan)(chan)，甚(shen)至單(dan)件(jian)生(sheng)產(chan)(chan)(chan)(chan)時(shi)也可以(yi)(yi)考慮用CNC加工(gong)(gong)(gong)中(zhong)(zhong)(zhong)心(xin)(xin)。
