  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)中心是高度(du)(du)機(ji)(ji)電一體化的(de)產品，工(gong)(gong)(gong)件裝夾后(hou)，數控系統能控制機(ji)(ji)床(chuang)(chuang)按(an)不同工(gong)(gong)(gong)序自動選(xuan)擇、更換刀(dao)具(ju)、自動對(dui)刀(dao)、自動改變主軸轉(zhuan)速、進給量(liang)等(deng)(deng)，可(ke)連續完成鉆、鏜、銑、鉸(jiao)、攻絲(si)等(deng)(deng)多種(zhong)工(gong)(gong)(gong)序，因而大大減(jian)少了工(gong)(gong)(gong)件裝夾時(shi)間(jian)、測(ce)量(liang)和機(ji)(ji)床(chuang)(chuang)調整等(deng)(deng)輔助工(gong)(gong)(gong)序時(shi)間(jian)，對(dui)加工(gong)(gong)(gong)形狀比較復雜，精度(du)(du)要(yao)求較高，品種(zhong)更換頻繁的(de)零件具(ju)有良好的(de)經(jing)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(yi)步發揮(hui)這(zhe)些優點，數控(kong)機床(chuang)(chuang)遂(sui)向“工序(xu)集中”，即(ji)一(yi)臺數控(kong)機床(chuang)(chuang)在一(yi)次裝(zhuang)夾零件(jian)后能完成多工序(xu)加工的數控(kong)機床(chuang)(chuang)(即(ji)加工中心)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(批)試切(qie)完(wan)后，程序和相關生(sheng)(sheng)產(chan)信息(xi)可保留下來，下次產(chan)品再(zai)生(sheng)(sheng)產(chan)時(shi)(shi)，只要很(hen)少的準(zhun)備時(shi)(shi)間就(jiu)可以開始(shi)生(sheng)(sheng)產(chan)。CNC加(jia)工(gong)(gong)中(zhong)心(xin)工(gong)(gong)時(shi)(shi)包括準(zhun)備工(gong)(gong)時(shi)(shi)和加(jia)工(gong)(gong)工(gong)(gong)時(shi)(shi)，CNC加(jia)工(gong)(gong)中(zhong)心(xin)把很(hen)長的單件準(zhun)備工(gong)(gong)時(shi)(shi)平均(jun)分配到每一個工(gong)(gong)件上，使每次生(sheng)(sheng)產(chan)的平均(jun)實(shi)際工(gong)(gong)時(shi)(shi)減少，生(sheng)(sheng)產(chan)周期大大縮短。

        （2）高精度(du)工(gong)件(jian)(jian):有些工(gong)件(jian)(jian)需求甚少(shao)，但屬關(guan)鍵部件(jian)(jian)，要(yao)求精度(du)高且(qie)工(gong)期短，用(yong)傳統(tong)工(gong)藝需用(yong)多臺機床協調工(gong)作，其周期長、效(xiao)率低(di)，在長工(gong)序流程中(zhong)(zhong)，受人為影響容(rong)易出(chu)廢品，從而造(zao)成重大(da)經(jing)濟損(sun)失(shi)。而采用(yong)CNC加工(gong)中(zhong)(zhong)心進行加工(gong),生產(chan)完全由程序自(zi)動控制(zhi).避免了長工(gong)序流程,減少(shao)了硬件(jian)(jian)投資及(ji)人為干擾(rao)，具(ju)有生產(chan)效(xiao)益高及(ji)質(zhi)量穩定的特點。

        （3）批(pi)(pi)量(liang)生(sheng)產(chan)的工(gong)(gong)(gong)(gong)(gong)件(jian):CNC加(jia)(jia)工(gong)(gong)(gong)(gong)(gong)中心(xin)(xin)生(sheng)產(chan)的柔性不僅體現(xian)在(zai)對(dui)特殊要求的快速(su)反(fan)應(ying)上，而且(qie)可(ke)(ke)以(yi)快速(su)實現(xian)批(pi)(pi)量(liang)生(sheng)產(chan)，以(yi)提高(gao)市場競爭能力。CNC加(jia)(jia)工(gong)(gong)(gong)(gong)(gong)中心(xin)(xin)適合于(yu)(yu)中小(xiao)批(pi)(pi)量(liang)生(sheng)產(chan)，特別是小(xiao)批(pi)(pi)量(liang)生(sheng)產(chan)，在(zai)應(ying)用CNC加(jia)(jia)工(gong)(gong)(gong)(gong)(gong)中心(xin)(xin)時。盡(jin)量(liang)使批(pi)(pi)量(liang)大(da)于(yu)(yu)經(jing)濟(ji)批(pi)(pi)量(liang),以(yi)達到良好的經(jing)濟(ji)效(xiao)果。隨著CNC加(jia)(jia)工(gong)(gong)(gong)(gong)(gong)中心(xin)(xin)的不斷發展，經(jing)濟(ji)批(pi)(pi)量(liang)越(yue)來越(yue)小(xiao)，對(dui)一些復雜工(gong)(gong)(gong)(gong)(gong)件(jian)，5-10件(jian)就可(ke)(ke)以(yi)生(sheng)產(chan)，甚至單件(jian)生(sheng)產(chan)時也可(ke)(ke)以(yi)考慮(lv)用CNC加(jia)(jia)工(gong)(gong)(gong)(gong)(gong)中心(xin)(xin)。
