  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)(gong)(gong)中心是高(gao)度機電一體化(hua)的產品(pin)，工(gong)(gong)(gong)件裝(zhuang)夾(jia)后，數控系統能控制機床(chuang)按不同(tong)工(gong)(gong)(gong)序自動選擇(ze)、更(geng)換刀(dao)具、自動對刀(dao)、自動改變主軸(zhou)轉速、進給(gei)量等，可連(lian)續完(wan)成鉆、鏜(tang)、銑(xian)、鉸(jiao)、攻絲等多(duo)種(zhong)工(gong)(gong)(gong)序，因而(er)大(da)大(da)減少了工(gong)(gong)(gong)件裝(zhuang)夾(jia)時(shi)間(jian)、測量和機床(chuang)調整等輔助工(gong)(gong)(gong)序時(shi)間(jian)，對加工(gong)(gong)(gong)形狀比較復(fu)雜，精度要求較高(gao)，品(pin)種(zhong)更(geng)換頻繁的零(ling)件具有良(liang)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發揮(hui)這(zhe)些優點，數控(kong)(kong)機床(chuang)(chuang)(chuang)遂(sui)向“工序集中”，即(ji)一臺數控(kong)(kong)機床(chuang)(chuang)(chuang)在一次裝(zhuang)夾零件后(hou)能完成多工序加工的數控(kong)(kong)機床(chuang)(chuang)(chuang)(即(ji)加工中心(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(jian)(批(pi))試切完后，程(cheng)序(xu)和相關生(sheng)產(chan)信息可保留下來，下次產(chan)品再生(sheng)產(chan)時(shi)(shi)(shi)，只要(yao)很(hen)少的準(zhun)(zhun)備時(shi)(shi)(shi)間(jian)就可以(yi)開始生(sheng)產(chan)。CNC加(jia)工(gong)(gong)(gong)中(zhong)心工(gong)(gong)(gong)時(shi)(shi)(shi)包(bao)括(kuo)準(zhun)(zhun)備工(gong)(gong)(gong)時(shi)(shi)(shi)和加(jia)工(gong)(gong)(gong)工(gong)(gong)(gong)時(shi)(shi)(shi)，CNC加(jia)工(gong)(gong)(gong)中(zhong)心把(ba)很(hen)長的單件(jian)準(zhun)(zhun)備工(gong)(gong)(gong)時(shi)(shi)(shi)平均(jun)分配到(dao)每一個工(gong)(gong)(gong)件(jian)上，使(shi)每次生(sheng)產(chan)的平均(jun)實際工(gong)(gong)(gong)時(shi)(shi)(shi)減少，生(sheng)產(chan)周期大大縮短。

        （2）高(gao)精度工(gong)(gong)件:有(you)些工(gong)(gong)件需(xu)求(qiu)甚少，但屬(shu)關鍵部件，要求(qiu)精度高(gao)且工(gong)(gong)期(qi)短，用傳統工(gong)(gong)藝(yi)需(xu)用多臺機(ji)床協調工(gong)(gong)作，其周期(qi)長、效(xiao)率低(di)，在長工(gong)(gong)序(xu)(xu)流程中，受人為影響容易(yi)出(chu)廢品(pin)，從而造成重大經濟損失(shi)。而采用CNC加(jia)工(gong)(gong)中心進行(xing)加(jia)工(gong)(gong),生(sheng)產(chan)完全由(you)程序(xu)(xu)自動控制(zhi).避免了長工(gong)(gong)序(xu)(xu)流程,減少了硬件投(tou)資及人為干擾(rao)，具有(you)生(sheng)產(chan)效(xiao)益高(gao)及質量(liang)穩定的特點。

        （3）批(pi)(pi)量(liang)(liang)(liang)生(sheng)(sheng)(sheng)產(chan)(chan)的(de)(de)工件(jian):CNC加工中(zhong)心(xin)(xin)生(sheng)(sheng)(sheng)產(chan)(chan)的(de)(de)柔性(xing)不僅體現(xian)在對特殊(shu)要(yao)求的(de)(de)快(kuai)速反(fan)應上(shang)，而且可(ke)(ke)以快(kuai)速實現(xian)批(pi)(pi)量(liang)(liang)(liang)生(sheng)(sheng)(sheng)產(chan)(chan)，以提高(gao)市場競爭能(neng)力。CNC加工中(zhong)心(xin)(xin)適合于(yu)中(zhong)小批(pi)(pi)量(liang)(liang)(liang)生(sheng)(sheng)(sheng)產(chan)(chan)，特別是小批(pi)(pi)量(liang)(liang)(liang)生(sheng)(sheng)(sheng)產(chan)(chan)，在應用CNC加工中(zhong)心(xin)(xin)時(shi)。盡量(liang)(liang)(liang)使批(pi)(pi)量(liang)(liang)(liang)大于(yu)經(jing)濟(ji)批(pi)(pi)量(liang)(liang)(liang),以達到良好的(de)(de)經(jing)濟(ji)效果。隨(sui)著CNC加工中(zhong)心(xin)(xin)的(de)(de)不斷發展(zhan)，經(jing)濟(ji)批(pi)(pi)量(liang)(liang)(liang)越來越小，對一些復雜(za)工件(jian)，5-10件(jian)就可(ke)(ke)以生(sheng)(sheng)(sheng)產(chan)(chan)，甚至單件(jian)生(sheng)(sheng)(sheng)產(chan)(chan)時(shi)也可(ke)(ke)以考慮用CNC加工中(zhong)心(xin)(xin)。
