  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)。加工中心是(shi)高度機電一體化的(de)產(chan)品(pin)，工件(jian)(jian)裝(zhuang)夾后，數控系統能控制機床(chuang)按不同工序(xu)自動(dong)選擇、更換刀具(ju)(ju)、自動(dong)對刀、自動(dong)改變主(zhu)軸轉速、進給量(liang)等(deng)，可連(lian)續完成鉆、鏜、銑、鉸、攻絲等(deng)多(duo)種工序(xu)，因而(er)大(da)大(da)減少了工件(jian)(jian)裝(zhuang)夾時(shi)間、測量(liang)和機床(chuang)調整(zheng)等(deng)輔助工序(xu)時(shi)間，對加工形狀比(bi)較復雜，精度要求較高，品(pin)種更換頻(pin)繁的(de)零(ling)件(jian)(jian)具(ju)(ju)有(you)良(liang)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(jia)為了進一步發(fa)揮這(zhe)些優點，數(shu)(shu)控(kong)機床(chuang)(chuang)遂向(xiang)“工(gong)(gong)(gong)序集中”，即一臺數(shu)(shu)控(kong)機床(chuang)(chuang)在一次裝(zhuang)夾零件后能完成多工(gong)(gong)(gong)序加工(gong)(gong)(gong)的數(shu)(shu)控(kong)機床(chuang)(chuang)(即加工(gong)(gong)(gong)中心(xin))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(jian)(jian)(批)試切完后，程序(xu)和(he)相關(guan)生產(chan)(chan)(chan)信息(xi)可保留下來，下次產(chan)(chan)(chan)品再(zai)生產(chan)(chan)(chan)時，只要很少(shao)(shao)的(de)準(zhun)(zhun)備時間就(jiu)可以開(kai)始生產(chan)(chan)(chan)。CNC加工(gong)(gong)中(zhong)心工(gong)(gong)時包(bao)括準(zhun)(zhun)備工(gong)(gong)時和(he)加工(gong)(gong)工(gong)(gong)時，CNC加工(gong)(gong)中(zhong)心把很長的(de)單(dan)件(jian)(jian)準(zhun)(zhun)備工(gong)(gong)時平均分配(pei)到每(mei)一個(ge)工(gong)(gong)件(jian)(jian)上(shang)，使每(mei)次生產(chan)(chan)(chan)的(de)平均實際(ji)工(gong)(gong)時減少(shao)(shao)，生產(chan)(chan)(chan)周期(qi)大大縮短。

        （2）高(gao)精度(du)工(gong)(gong)(gong)(gong)件(jian):有些工(gong)(gong)(gong)(gong)件(jian)需求甚少(shao)，但屬關鍵部件(jian)，要求精度(du)高(gao)且工(gong)(gong)(gong)(gong)期短，用(yong)傳(chuan)統工(gong)(gong)(gong)(gong)藝需用(yong)多臺機床協(xie)調工(gong)(gong)(gong)(gong)作，其周期長、效率低(di)，在長工(gong)(gong)(gong)(gong)序(xu)流程(cheng)中，受人為影(ying)響容易出廢品，從而(er)造成重大經濟損失。而(er)采用(yong)CNC加工(gong)(gong)(gong)(gong)中心進行加工(gong)(gong)(gong)(gong),生產(chan)完全由(you)程(cheng)序(xu)自動控制.避免了(le)長工(gong)(gong)(gong)(gong)序(xu)流程(cheng),減少(shao)了(le)硬(ying)件(jian)投資(zi)及人為干擾，具有生產(chan)效益高(gao)及質量(liang)穩定(ding)的(de)特點。

        （3）批(pi)(pi)(pi)量(liang)生(sheng)產(chan)(chan)(chan)(chan)的工件:CNC加工中(zhong)心(xin)(xin)生(sheng)產(chan)(chan)(chan)(chan)的柔性(xing)不(bu)僅體(ti)現在對(dui)特殊要求(qiu)的快速反應上，而且(qie)可(ke)(ke)以快速實現批(pi)(pi)(pi)量(liang)生(sheng)產(chan)(chan)(chan)(chan)，以提高(gao)市場競(jing)爭能(neng)力。CNC加工中(zhong)心(xin)(xin)適合于中(zhong)小批(pi)(pi)(pi)量(liang)生(sheng)產(chan)(chan)(chan)(chan)，特別是小批(pi)(pi)(pi)量(liang)生(sheng)產(chan)(chan)(chan)(chan)，在應用CNC加工中(zhong)心(xin)(xin)時。盡量(liang)使(shi)批(pi)(pi)(pi)量(liang)大(da)于經濟批(pi)(pi)(pi)量(liang),以達(da)到良好的經濟效果。隨著CNC加工中(zhong)心(xin)(xin)的不(bu)斷發展，經濟批(pi)(pi)(pi)量(liang)越來越小，對(dui)一些(xie)復(fu)雜工件，5-10件就(jiu)可(ke)(ke)以生(sheng)產(chan)(chan)(chan)(chan)，甚至單件生(sheng)產(chan)(chan)(chan)(chan)時也可(ke)(ke)以考慮用CNC加工中(zhong)心(xin)(xin)。
