加(jia)(jia)(jia)工(gong)中(zhong)(zhong)心(xin)(xin)常(chang)按(an)主(zhu)軸在(zai)(zai)空(kong)間(jian)所處(chu)的(de)狀(zhuang)態(tai)分為立式(shi)加(jia)(jia)(jia)工(gong)中(zhong)(zhong)心(xin)(xin)和臥式(shi)加(jia)(jia)(jia)工(gong)中(zhong)(zhong)心(xin)(xin)，加(jia)(jia)(jia)工(gong)中(zhong)(zhong)心(xin)(xin)的(de)主(zhu)軸在(zai)(zai)空(kong)間(jian)處(chu)于垂直狀(zhuang)態(tai)的(de)稱為立式(shi)加(jia)(jia)(jia)工(gong)中(zhong)(zhong)心(xin)(xin)，主(zhu)軸在(zai)(zai)空(kong)間(jian)處(chu)于水(shui)(shui)平狀(zhuang)態(tai)的(de)稱為臥式(shi)加(jia)(jia)(jia)工(gong)中(zhong)(zhong)心(xin)(xin)。主(zhu)軸可作垂直和水(shui)(shui)平轉換的(de)，稱為立臥式(shi)加(jia)(jia)(jia)工(gong)中(zhong)(zhong)心(xin)(xin)或五(wu)面加(jia)(jia)(jia)工(gong)中(zhong)(zhong)心(xin)(xin)，也(ye)稱復合加(jia)(jia)(jia)工(gong)中(zhong)(zhong)心(xin)(xin)。

按加(jia)工中心運動坐(zuo)標數和(he)同時(shi)控制(zhi)的(de)坐(zuo)標數分(fen)：有三(san)軸(zhou)二聯(lian)(lian)(lian)動、三(san)軸(zhou)三(san)聯(lian)(lian)(lian)動、四軸(zhou)三(san)聯(lian)(lian)(lian)動、五軸(zhou)四聯(lian)(lian)(lian)動、六(liu)軸(zhou)五聯(lian)(lian)(lian)動等(deng)。三(san)軸(zhou)、四軸(zhou)是(shi)(shi)指加(jia)工中心具(ju)有的(de)運動坐(zuo)標數，聯(lian)(lian)(lian)動是(shi)(shi)指控制(zhi)系統可以同時(shi)控制(zhi)運動的(de)坐(zuo)標數，從而(er)實(shi)現刀具(ju)相對工件(jian)的(de)位置和(he)速度控制(zhi)。

五軸cnc加工

按工(gong)(gong)作臺(tai)的數(shu)量(liang)和(he)功(gong)能分：有單工(gong)(gong)作臺(tai)加工(gong)(gong)中心、雙(shuang)工(gong)(gong)作臺(tai)加工(gong)(gong)中心，和(he)多工(gong)(gong)作臺(tai)加工(gong)(gong)中心。

按加工精度分：有(you)普通加工中(zhong)(zhong)心和高(gao)精度加工中(zhong)(zhong)心。普通加工中(zhong)(zhong)心，分辨(bian)率(lv)為1μm，很大進給速(su)度15～25m/min，定(ding)(ding)位精度l0μm左(zuo)右。高(gao)精度加工中(zhong)(zhong)心、分辨(bian)率(lv)為0.1μm，很大進給速(su)度為15～100m/min，定(ding)(ding)位精度為2μm左(zuo)右。介于2～l0μm之間的(de)，以±5μm較多，可稱精密(mi)級。
