Vertical Milling Machine. 1. A cutter is mounted on the arbor. Here instead of an arbor, the cutter is mounted directly on the spindle. 2. In the Horizontal Milling machine, a cutter is fixed not move up and down. But here the cutter moves up and down. 3. The spindle is horizontal and parallel to the work table.
Work on a milling machine is most often held in a vise clamped onto the bed. To make features aligned with the edges of the stock, it's neccessary to align the vise with the feed axes of the mill. To do this, mount the vise on the bed and secure it with T-bolts, but only lightly so as to permit adjustment of the orientation of the vise.
RAM-TYPE MILLING MACHINE The ram-type milling machine is characterized by a spindle mounted to a movable housing on the column to permit positioning the milling cutter forward or rearward in a horizontal plane. Two popular ram-type milling machines are the universal milling machine and the swivel cutter head ram-type milling machine.

A milling machine is a machine tool in which metal is removed by means of a revolving cutter with many teeth, each tooth having a cutting edge which removes metal from a workpiece. The work is supported by various methods on the work table and may be fed to the cutter, longitudinally, transversely or vertically.
The most advanced CNC milling-machines, the multiaxis machine, add two more axes in addition to the three normal axes (XYZ). Horizontal milling machines also have a C or Q axis, allowing the horizontally mounted workpiece to be rotated, essentially allowing asymmetric and eccentric turning. The fifth axis (B axis) controls the tilt of the tool ...
