the mill include but are not limited to side and face milling, fly cutting, and precision boring. Mills are classified on the basis of the position of their spindle. The spindle Operates in either a vertical or horizontal position. The amount of horsepower the mill is able to supply to the cutter is also often important.

Vertical stirred mills have been widely applied in the minerals industry, due to its greater efficiency in comparison with conventional tumbling mills. In this context, the agitator liner wear plays an important role in maintenance planning and operational costs. In this paper, we use the discrete element method (DEM) wear simulation to evaluate the screw liner wear.

Milling cutters are an essential component of a milling machine. As the name suggests, it is the cutting tool responsible for scraping the material outside the workpiece. All milling machines have a cutter. During a typical milling operation, the Cutter moves perpendicular to its axis, allowing it to remove material from the workpiece at the perimeter of the Cutter.

A vertical milling machine shapes metal into a predetermined form, from ball bearings, to airplane parts or flywheels. A vertical mill is used typically in a machine shop; however, some people work from their own garage. A vertical mill usually works with a very tight tolerance, meaning there is a very little margin of error.
