The vertical milling machine is again sub-divided in two types: (a) Bed Mill: In bed mills, spindle always moves parallel to its own axis while the table moves perpendicular to the axis of the spindle. (b) Turret Mill: In turret mills, spindle is in stationary position and table is moved in such a way that it will always perpendicular and parallel to the axis of spindle during cutting operation.

On some universal knee and column milling machine, the feed is obtained by turning the speed selection handle until the desired rate of feed is indicated on the feed dial. Most of the milling machines have a rapid traverse lever that can be engaged when a temporary increase in the speed of the longitudinal, transverse or vertical feeds is required.

Milling is a common machining process that involves the use of a machine, known as a milling machine, to remove material from a stationary workpiece using a rotating cutting tool. With milling, the workpiece remains stationary, whereas the cutting tool rotates. As the rotating cutting tool presses against the workpiece, it removes material.
