The medium element material and shape are determined by the material hardness and configuration of workpiece to be abraded, and the shape may be sphere, ellipse, cone or other curved shapes, consituted by numbers of protruding perimeter edges on the shell surface, to abrade by means of three-dimension vibratory such as tumbling in result of effective and quality workpiece finishing.
