加(jia)(jia)(jia)(jia)工(gong)(gong)中(zhong)心(xin)常按主(zhu)軸(zhou)(zhou)(zhou)在空(kong)間(jian)所處(chu)的(de)狀(zhuang)(zhuang)態(tai)分為(wei)立(li)(li)式(shi)(shi)加(jia)(jia)(jia)(jia)工(gong)(gong)中(zhong)心(xin)和臥(wo)(wo)式(shi)(shi)加(jia)(jia)(jia)(jia)工(gong)(gong)中(zhong)心(xin)，加(jia)(jia)(jia)(jia)工(gong)(gong)中(zhong)心(xin)的(de)主(zhu)軸(zhou)(zhou)(zhou)在空(kong)間(jian)處(chu)于(yu)垂直(zhi)狀(zhuang)(zhuang)態(tai)的(de)稱(cheng)為(wei)立(li)(li)式(shi)(shi)加(jia)(jia)(jia)(jia)工(gong)(gong)中(zhong)心(xin)，主(zhu)軸(zhou)(zhou)(zhou)在空(kong)間(jian)處(chu)于(yu)水平狀(zhuang)(zhuang)態(tai)的(de)稱(cheng)為(wei)臥(wo)(wo)式(shi)(shi)加(jia)(jia)(jia)(jia)工(gong)(gong)中(zhong)心(xin)。主(zhu)軸(zhou)(zhou)(zhou)可作垂直(zhi)和水平轉換的(de)，稱(cheng)為(wei)立(li)(li)臥(wo)(wo)式(shi)(shi)加(jia)(jia)(jia)(jia)工(gong)(gong)中(zhong)心(xin)或五面加(jia)(jia)(jia)(jia)工(gong)(gong)中(zhong)心(xin)，也稱(cheng)復(fu)合加(jia)(jia)(jia)(jia)工(gong)(gong)中(zhong)心(xin)。

五軸加工零件

按加工(gong)中(zhong)心(xin)運動坐(zuo)標(biao)數(shu)(shu)和同時控制(zhi)的坐(zuo)標(biao)數(shu)(shu)分(fen)：有三軸二聯動、三軸三聯動、四(si)軸三聯動、五(wu)軸四(si)聯動、六軸五(wu)聯動等。三軸、四(si)軸是指(zhi)加工(gong)中(zhong)心(xin)具有的運動坐(zuo)標(biao)數(shu)(shu)，聯動是指(zhi)控制(zhi)系統可以同時控制(zhi)運動的坐(zuo)標(biao)數(shu)(shu)，從而實現刀具相對工(gong)件(jian)的位置和速(su)度(du)控制(zhi)。

按工(gong)(gong)(gong)(gong)作(zuo)臺(tai)的數量和功能分(fen)：有(you)單(dan)工(gong)(gong)(gong)(gong)作(zuo)臺(tai)加(jia)工(gong)(gong)(gong)(gong)中心(xin)、雙(shuang)工(gong)(gong)(gong)(gong)作(zuo)臺(tai)加(jia)工(gong)(gong)(gong)(gong)中心(xin)，和多工(gong)(gong)(gong)(gong)作(zuo)臺(tai)加(jia)工(gong)(gong)(gong)(gong)中心(xin)。

按加工(gong)精度(du)分：有普通(tong)加工(gong)中(zhong)(zhong)心(xin)和高精度(du)加工(gong)中(zhong)(zhong)心(xin)。普通(tong)加工(gong)中(zhong)(zhong)心(xin)，分辨(bian)率為1μm，很(hen)大進給速度(du)15～25m/min，定(ding)位精度(du)l0μm左右(you)。高精度(du)加工(gong)中(zhong)(zhong)心(xin)、分辨(bian)率為0.1μm，很(hen)大進給速度(du)為15～100m/min，定(ding)位精度(du)為2μm左右(you)。介于(yu)2～l0μm之間(jian)的(de)，以±5μm較多，可(ke)稱精密級。
