What is the difference between horizontal and vertical milling machine cutting tool?
Horizontal Milling Machine Cutting tool is positioned horizontally and parallel to the worktable. The main spindle axis of any machine is always called the Z axis. The movement of the table left and right is the X axis, up and down is the Y axis. 2. Vertical Milling Machine Cutting tool is positioned vertically and perpendicular to the worktable.
What is a milling machine?
Milling machine Milling: is a metal cutting operation in which the excess material from the work piece is removed by rotating multipoint cutting tool called milling cutter. A milling machine is a machine tool that removes metal as the work is fed against a rotating multipoint cutter.
