An optimized arrangement of the toolholders on the milling drum and clever tooling of the drum edges ensure a clean milling texture and quiet operation of the machine. The milling drum is fitted with welded toolholders and works against the direction of travel in an effectively sealed milling chamber.

Plain milling cutters that are more than 3/4 inch in width are usually made with spiral or helical teeth. A plain spiral-tooth milling cutter produces a better and smoother finish and requires less power to operate. A plain helical-tooth milling cutter is especially desirable when milling an uneven surface or one with holes in it. Types of Teeth

Fixture used for the conventional drilling and the helical milling experiments: (a) drawing of fixture and (b) fixture on the table of the coordinate measuring machine Full size image A Zeiss UMC 850 coordinate measuring machine (CMM) was used to measure the diameter and circularity errors of the holes.

Unlike ball milling where the whole vessel rotates or oscillate/vibrates whilst in operation, the vessel remains stationary in media milling. Movement of the balls is initiated by a stirring or agitating device, often represented by several discs mounted on a central shaft rotating at high velocities, 20 000 rpm and above, within the vessel.
