The working principle of the Milling machine is, It employed in the metal removing operation on a milling machine is that the work is rigidly clamped on the table of the machine and the revolving cutter which has multiple teeth is mounted on the arbor. The cutter revolves at high speed and the work is fed slowly past the cutter.

Basic principle Ball mill is generally used to grind material 1/4 inch and finer, down to the particle size of 20 to 75 microns. To achieve a reasonable efficiency with ball mills, they must be operated in a closed system. There is a specific operating speed for most efficient grinding. At a certain point, controlled by the mill speed, the load ...

Milling is basically known as most common type of machining process of removing the unwanted material from workpiece. Workpiece will be machined by inserting against one rotating cutter and rotating cutter will have a number of cutting sharp edges. Unwanted material will be cut away in small-small chips to secure the desired shape.
