CNC mills are often classified by the number of axes on which they can operate or spindle directions. 1. Vertical Mill. A vertical mill or milling machine's spindle axis is vertically oriented, which means the cutting tools on the spindle will shape the materials vertically, and the cutters move while the workpiece remains stationary, the machines can cut into the part easily.
