加工中心（英文縮寫(xie)為(wei)CNC 全稱為(wei)Computerized Numerical Control），翻(fan)譯過(guo)來就(jiu)是(shi)：電腦數值控(kong)制。俗稱“數控(kong)”，是(shi)帶有刀庫和自動(dong)換(huan)刀裝置的(de)一種高度自動(dong)化的(de)多(duo)功(gong)能數控(kong)機床。

CNC加(jia)工(gong)(gong)具有加(jia)工(gong)(gong)質量(liang)穩定，加(jia)工(gong)(gong)精(jing)度高(gao)，重復精(jing)度高(gao)，可加(jia)工(gong)(gong)復雜型(xing)面，加(jia)工(gong)(gong)效率很高(gao)等優點。數控(kong)技術的不斷發(fa)展也逐步(bu)應(ying)用到加(jia)工(gong)(gong)制造業中，因此數控(kong)機床（cnc加(jia)工(gong)(gong)中心）應(ying)運而生。

CNC加工中(zhong)心在國(guo)內(nei)尤(you)其是華(hua)南、華(hua)東地區得到快速發展。據統計，每(mei)年用于加工手機外殼的(de)CNC數量(liang)都(dou)在幾十萬(wan)的(de)數量(liang)級，市場巨大！

加(jia)(jia)工(gong)(gong)中心(xin)(xin)(xin)通(tong)常以(yi)主(zhu)軸(zhou)(zhou)與工(gong)(gong)作臺(tai)相對位置分類，分為臥(wo)式、立(li)式和萬(wan)i能加(jia)(jia)工(gong)(gong)中心(xin)(xin)(xin)。1）臥(wo)式加(jia)(jia)工(gong)(gong)中心(xin)(xin)(xin)：是(shi)(shi)指(zhi)主(zhu)軸(zhou)(zhou)軸(zhou)(zhou)線(xian)與工(gong)(gong)作臺(tai)平行(xing)設置的(de)(de)加(jia)(jia)工(gong)(gong)中心(xin)(xin)(xin)，主(zhu)要(yao)適(shi)用于加(jia)(jia)工(gong)(gong)箱體類零件。2）立(li)式加(jia)(jia)工(gong)(gong)中心(xin)(xin)(xin)：是(shi)(shi)指(zhi)主(zhu)軸(zhou)(zhou)軸(zhou)(zhou)線(xian)與工(gong)(gong)作臺(tai)垂直設置的(de)(de)加(jia)(jia)工(gong)(gong)中心(xin)(xin)(xin)，主(zhu)要(yao)適(shi)用于加(jia)(jia)工(gong)(gong)板類、盤類、模具及(ji)小型(xing)殼體類復雜零件。3）萬(wan)i能加(jia)(jia)工(gong)(gong)中心(xin)(xin)(xin)(又稱多軸(zhou)(zhou)聯動(dong)型(xing)加(jia)(jia)工(gong)(gong)中心(xin)(xin)(xin))：是(shi)(shi)指(zhi)通(tong)過加(jia)(jia)工(gong)(gong)主(zhu)軸(zhou)(zhou)軸(zhou)(zhou)線(xian)與工(gong)(gong)作臺(tai)回轉軸(zhou)(zhou)線(xian)的(de)(de)角度可控(kong)制聯動(dong)變化，完成復雜空(kong)間(jian)曲面加(jia)(jia)工(gong)(gong)的(de)(de)加(jia)(jia)工(gong)(gong)中心(xin)(xin)(xin)。適(shi)用于具有復雜空(kong)間(jian)曲面的(de)(de)葉輪(lun)轉子、模具、刃具等(deng)工(gong)(gong)件的(de)(de)加(jia)(jia)工(gong)(gong)。

加(jia)工(gong)中(zhong)(zhong)心常按主軸(zhou)在(zai)空間所處的狀態(tai)分為(wei)立式(shi)(shi)(shi)加(jia)工(gong)中(zhong)(zhong)心、臥式(shi)(shi)(shi)加(jia)工(gong)中(zhong)(zhong)心、龍門加(jia)工(gong)中(zhong)(zhong)心、萬(wan)i能(neng)加(jia)工(gong)中(zhong)(zhong)心。加(jia)工(gong)中(zhong)(zhong)心的主軸(zhou)在(zai)空間處于(yu)垂直狀態(tai)的稱(cheng)為(wei)立式(shi)(shi)(shi)加(jia)工(gong)中(zhong)(zhong)心，主軸(zhou)在(zai)空間處于(yu)水平狀態(tai)的稱(cheng)為(wei)臥式(shi)(shi)(shi)加(jia)工(gong)中(zhong)(zhong)心。

立式(shi)加工(gong)中(zhong)心(xin)：結構形式(shi)多為(wei)固定立柱式(shi)，工(gong)作(zuo)(zuo)臺為(wei)長方形，適合加工(gong)盤、套、板(ban)類零件(jian)。立式(shi)加工(gong)中(zhong)心(xin)通常有三個直線運(yun)動坐標，XYZ軸(zhou)，還可(ke)以在工(gong)作(zuo)(zuo)臺上安裝一個第四軸(zhou)A軸(zhou)。

立式(shi)加(jia)工(gong)中(zhong)心的優點：裝夾方便(bian)，便(bian)于操作，便(bian)于觀察加(jia)工(gong)情況，泰州模具加(jia)工(gong)，調(diao)試程序方便(bian)，但(dan)受(shou)立柱高(gao)度和換刀機(ji)構的影(ying)響，不能加(jia)工(gong)太高(gao)的零(ling)件。立式(shi)加(jia)工(gong)中(zhong)心結構簡單(dan)，占地面積小，價格(ge)較(jiao)低。

臥(wo)式加(jia)(jia)工中心：通(tong)常(chang)采用移動(dong)式立(li)柱(zhu)，模具加(jia)(jia)工公司，主軸箱在兩(liang)立(li)柱(zhu)之(zhi)間，沿導軌上下移動(dong)。臥(wo)式加(jia)(jia)工中心通(tong)常(chang)有三個直線運動(dong)坐標，模具數控加(jia)(jia)工，面對機床(chuang)，左右移動(dong)為(wei)(wei)X軸，前后移動(dong)為(wei)(wei)Z軸，上下移動(dong)為(wei)(wei)Y軸。臥(wo)式加(jia)(jia)工中心還可以在工作臺(tai)上安裝一個第四軸A軸。可以加(jia)(jia)工螺旋(xuan)線類、圓柱(zhu)凸輪等(deng)零件(jian)。
