mills produce sub-micron particle sizes by employing beads ranging in size from 0.1 to 1 mm. Attrition milling is simple and effective. Feed material is placed in a stationary tank with the grinding media. A rotating shaft with arms or discs then agitates the material and media. Both impact and shearing action result in size re-duction as well as homogeneous particle dispersion with very ...

Peel grinding operates in a similar mode removing a narrow strip of material as the grinding wheel is traversed along the programmed path. A typical operation is shown schematically in Figure 6.9. Grinding forces are minimized by using a very high-speed narrow superabrasive grinding wheel. Low grinding forces limit workpiece deflections and allow good accuracies to be achieved.
