(1) CNC vertical milling machine. The spindle axis of CNC vertical milling machine is perpendicular to the horizontal plane. This kind of milling machine accounts for the majority of CNC milling machines and has the widest range of applications. At present, three-axis CNC vertical milling machines account for the majority of CNC milling machines, which can generally carry out three-axis linkage processing.
(2) Horizontal CNC milling machine, the spindle axis of the horizontal CNC milling machine is parallel to the horizontal plane. In order to expand the processing range and expand the functions, the horizontal CNC milling machine usually adopts the way of adding CNC turntable or universal CNC turntable to realize four axis and five axis linkage processing. In this way, it can not only process the continuous rotary contour on the side of the workpiece, but also change the processing position of the part through the turntable in one clamping, that is, the commonly known station, to process multiple positions or working surfaces.
(3) The spindle of this kind of milling machine can be converted, and the vertical and horizontal processing can be carried out on the same CNC milling machine. It also has the functions of vertical and horizontal milling machines.
