The end milling is the operation of producing a flat surface which may be vertical, horizontal or at an angle in reference to the table surface. The cutter used is an end mill. The end milling cutters are also used for the production of slots, grooves or keyways. A vertical milling machine is more suitable for end milling operation.

On Vertical Mills, the 4th Axis is frequently parallel to X or Y, and is laid down. On a Horizontal Mill, the 4th Axis is also parallel to X or Y, but it is standing up. Both methods work great, but the horizontal mill's standing 4th axis frequently has more clearance available since the work is never trapped between the table and the axis.
