  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)(gong)(gong)(gong)中心是(shi)高(gao)度(du)機電一體(ti)化(hua)的產品(pin)，工(gong)(gong)(gong)(gong)件裝(zhuang)夾(jia)(jia)后，數控(kong)(kong)系(xi)統能(neng)控(kong)(kong)制機床按不同工(gong)(gong)(gong)(gong)序(xu)自動選擇、更換刀(dao)具、自動對(dui)刀(dao)、自動改變主軸轉速、進給量等(deng)，可連續完成(cheng)鉆、鏜、銑、鉸、攻絲等(deng)多種(zhong)(zhong)工(gong)(gong)(gong)(gong)序(xu)，因而大(da)大(da)減(jian)少了(le)工(gong)(gong)(gong)(gong)件裝(zhuang)夾(jia)(jia)時間、測量和機床調整等(deng)輔(fu)助工(gong)(gong)(gong)(gong)序(xu)時間，對(dui)加工(gong)(gong)(gong)(gong)形狀比較(jiao)復雜，精度(du)要求較(jiao)高(gao)，品(pin)種(zhong)(zhong)更換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(jia)為了進(jin)一(yi)步發揮這些優點，數控機床遂向(xiang)“工(gong)(gong)(gong)序集中”，即(ji)(ji)一(yi)臺數控機床在一(yi)次裝(zhuang)夾零件后(hou)能完成(cheng)多工(gong)(gong)(gong)序加工(gong)(gong)(gong)的數控機床(即(ji)(ji)加工(gong)(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(批)試切完后，程序和(he)相關(guan)生(sheng)產(chan)信息可保留(liu)下來，下次產(chan)品(pin)再生(sheng)產(chan)時，只要很(hen)少的準備(bei)時間就可以開始生(sheng)產(chan)。CNC加工(gong)(gong)中心工(gong)(gong)時包(bao)括準備(bei)工(gong)(gong)時和(he)加工(gong)(gong)工(gong)(gong)時，CNC加工(gong)(gong)中心把很(hen)長的單件準備(bei)工(gong)(gong)時平均分(fen)配到每一(yi)個工(gong)(gong)件上，使每次生(sheng)產(chan)的平均實際工(gong)(gong)時減少，生(sheng)產(chan)周期大大縮(suo)短。

        （2）高精度工(gong)(gong)件(jian):有些工(gong)(gong)件(jian)需(xu)求甚少，但屬關鍵部件(jian)，要求精度高且(qie)工(gong)(gong)期短(duan)，用傳統工(gong)(gong)藝需(xu)用多臺機床(chuang)協調工(gong)(gong)作，其周期長(chang)(chang)、效率低(di)，在長(chang)(chang)工(gong)(gong)序(xu)流程中(zhong)，受人為影(ying)響(xiang)容易出廢品(pin)，從(cong)而造(zao)成重大經(jing)濟損(sun)失。而采用CNC加工(gong)(gong)中(zhong)心進行加工(gong)(gong),生(sheng)產完全由程序(xu)自動控制.避免了(le)(le)長(chang)(chang)工(gong)(gong)序(xu)流程,減少了(le)(le)硬件(jian)投資(zi)及人為干擾，具有生(sheng)產效益高及質(zhi)量穩定的特點。

        （3）批量(liang)(liang)生(sheng)產(chan)(chan)(chan)(chan)的(de)工(gong)(gong)(gong)(gong)件:CNC加(jia)工(gong)(gong)(gong)(gong)中心生(sheng)產(chan)(chan)(chan)(chan)的(de)柔性不(bu)僅體現在(zai)對(dui)特(te)殊要求的(de)快速反(fan)應上，而且(qie)可以(yi)快速實現批量(liang)(liang)生(sheng)產(chan)(chan)(chan)(chan)，以(yi)提高市場競(jing)爭能力(li)。CNC加(jia)工(gong)(gong)(gong)(gong)中心適(shi)合于中小(xiao)批量(liang)(liang)生(sheng)產(chan)(chan)(chan)(chan)，特(te)別(bie)是小(xiao)批量(liang)(liang)生(sheng)產(chan)(chan)(chan)(chan)，在(zai)應用CNC加(jia)工(gong)(gong)(gong)(gong)中心時(shi)。盡量(liang)(liang)使批量(liang)(liang)大于經濟批量(liang)(liang),以(yi)達到良好的(de)經濟效果。隨著CNC加(jia)工(gong)(gong)(gong)(gong)中心的(de)不(bu)斷發展(zhan)，經濟批量(liang)(liang)越(yue)來(lai)越(yue)小(xiao)，對(dui)一些復(fu)雜工(gong)(gong)(gong)(gong)件，5-10件就可以(yi)生(sheng)產(chan)(chan)(chan)(chan)，甚至單件生(sheng)產(chan)(chan)(chan)(chan)時(shi)也可以(yi)考慮用CNC加(jia)工(gong)(gong)(gong)(gong)中心。
