  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(shi)高度(du)機電一體化的產品，工(gong)(gong)(gong)件(jian)裝(zhuang)夾后，數(shu)控系(xi)統能控制機床(chuang)(chuang)按不同(tong)工(gong)(gong)(gong)序自(zi)動選擇、更(geng)(geng)換刀具(ju)、自(zi)動對刀、自(zi)動改變主軸轉(zhuan)速(su)、進給量等(deng)，可連續完(wan)成鉆、鏜、銑、鉸、攻絲(si)等(deng)多種工(gong)(gong)(gong)序，因而大大減少了工(gong)(gong)(gong)件(jian)裝(zhuang)夾時(shi)間、測量和機床(chuang)(chuang)調(diao)整等(deng)輔(fu)助工(gong)(gong)(gong)序時(shi)間，對加工(gong)(gong)(gong)形狀比較(jiao)復雜，精度(du)要求較(jiao)高，品種更(geng)(geng)換頻繁(fan)的零件(jian)具(ju)有良好的經濟效果。

        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(le)進一(yi)步發揮這些優點(dian)，數(shu)控(kong)機(ji)床(chuang)(chuang)遂向“工(gong)序(xu)集(ji)中”，即一(yi)臺數(shu)控(kong)機(ji)床(chuang)(chuang)在一(yi)次裝夾零件后能完(wan)成多工(gong)序(xu)加工(gong)的數(shu)控(kong)機(ji)床(chuang)(chuang)(即加工(gong)中心)方面(mian)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(hou)，程(cheng)序(xu)和(he)相(xiang)關生產信息可保留(liu)下(xia)來，下(xia)次(ci)產品再生產時(shi)，只要很少的準(zhun)(zhun)備(bei)時(shi)間就可以(yi)開始生產。CNC加(jia)工(gong)(gong)(gong)(gong)中心(xin)工(gong)(gong)(gong)(gong)時(shi)包括準(zhun)(zhun)備(bei)工(gong)(gong)(gong)(gong)時(shi)和(he)加(jia)工(gong)(gong)(gong)(gong)工(gong)(gong)(gong)(gong)時(shi)，CNC加(jia)工(gong)(gong)(gong)(gong)中心(xin)把很長的單件準(zhun)(zhun)備(bei)工(gong)(gong)(gong)(gong)時(shi)平均分配到每一個工(gong)(gong)(gong)(gong)件上，使每次(ci)生產的平均實際工(gong)(gong)(gong)(gong)時(shi)減少，生產周期大(da)(da)大(da)(da)縮短。

        （2）高精度工(gong)件:有些工(gong)件需(xu)求甚少，但屬關鍵(jian)部(bu)件，要求精度高且(qie)工(gong)期短，用傳統工(gong)藝需(xu)用多臺機床協(xie)調工(gong)作，其周期長(chang)、效率低，在長(chang)工(gong)序(xu)(xu)流程(cheng)中，受人(ren)為影響容易出廢品，從而造(zao)成重大經(jing)濟損失。而采用CNC加工(gong)中心進行(xing)加工(gong),生(sheng)產完全(quan)由(you)程(cheng)序(xu)(xu)自(zi)動控制.避(bi)免了長(chang)工(gong)序(xu)(xu)流程(cheng),減少了硬件投資及人(ren)為干擾(rao)，具有生(sheng)產效益(yi)高及質(zhi)量穩定的(de)特(te)點。

        （3）批(pi)量(liang)生(sheng)(sheng)產的(de)工(gong)(gong)(gong)件:CNC加(jia)(jia)工(gong)(gong)(gong)中(zhong)心(xin)生(sheng)(sheng)產的(de)柔(rou)性不僅(jin)體(ti)現在(zai)對特殊要求(qiu)的(de)快速反應(ying)(ying)上(shang)，而且可以(yi)(yi)快速實現批(pi)量(liang)生(sheng)(sheng)產，以(yi)(yi)提高(gao)市場競爭能力。CNC加(jia)(jia)工(gong)(gong)(gong)中(zhong)心(xin)適(shi)合于中(zhong)小批(pi)量(liang)生(sheng)(sheng)產，特別是小批(pi)量(liang)生(sheng)(sheng)產，在(zai)應(ying)(ying)用(yong)CNC加(jia)(jia)工(gong)(gong)(gong)中(zhong)心(xin)時。盡量(liang)使批(pi)量(liang)大于經(jing)(jing)濟批(pi)量(liang),以(yi)(yi)達到良好的(de)經(jing)(jing)濟效果。隨著CNC加(jia)(jia)工(gong)(gong)(gong)中(zhong)心(xin)的(de)不斷(duan)發展，經(jing)(jing)濟批(pi)量(liang)越來(lai)越小，對一些(xie)復雜工(gong)(gong)(gong)件，5-10件就可以(yi)(yi)生(sheng)(sheng)產，甚至單件生(sheng)(sheng)產時也可以(yi)(yi)考慮(lv)用(yong)CNC加(jia)(jia)工(gong)(gong)(gong)中(zhong)心(xin)。
