Milling operations remove material by feeding a workpiece into a rotating cutting tool with sharp teeth, such as an end mill or face mill. Calculations use the desired tool diameter, number of teeth, cutting speed, and cutting feed, which should be chosen based on the specific cutting conditions, including the workpiece material and tool material.
Optimum choice of the make-up ball sizes for maximum
Sep 01, 2013· The ball size is one of the critical factors for determining the mill performance of ball mills.
