Mill machining and material removal is typically made by a rotary cutter held in a spindle. Cutting options are more sophisticated and variable than a drill press by virtue of a moveable table and/or vise (x and yaxes) and vertical spindle movement (zaxis). Many vertical mills also have a rotatable turret for the upper cutting head which ...
