结构简单，占地面积小，价格低，配备各种附件后，可进行大部分工件的加工。大型龙门式加工中心，主轴多为垂直设置，尤其使用于大型或形状复杂的工件，像航空、航天工业及大型汽轮机上的某些零件的加工都需要用这类多坐标龙门式加工中心。五面加工中心，这种加工中心具有立式和卧式加工中心的功能，在工件一次装夹后，能完成除安装面外的所有五个面的加工，这种加工方式可以使工件的形状误差降到最低，省去二次装夹工作，从而提高生产效率，降低加工成本。3（2）按工艺用途分类有按工艺用途分类有按工艺用途分类有按工艺用途分类有镗铣加工中心，分为立式樘铣加工中心、卧式樘铣加工中心和龙门樘铣加工中心。其加工工艺以樘铣为主，用于箱体，壳体以及各种复杂零件特殊曲线和曲面轮廓的多工序加工，适合多品种小批量生产。复合加工中心，主要指五面复合加工，主轴头可自动回转，进行立，卧加工，在主轴自动回转后，在水平和垂直方向实现知道变换。（3）按特殊功能分类有按特殊功能分类有按特殊功能分类有按特殊功能分类有单工作台、双工作台加工中心；单轴、双轴、三轴及可换主轴箱的加工中心；立式转塔加工中心和卧式转塔加工中心；
