Vertical Milling Machines. In vertical mills, the spindle axis is vertically oriented. Milling cutters are held in the spindle and rotate on its axis. Typically the spindle can be extended or the table raised or lowered to produce the same effect, allowing for plunge cuts and drilling. The two kinds of vertical mills are bed mills and turret mills.
