<p>A tool for abrading a workpiece to smooth the surface thereof. In one embodiment, the tool is an ultrasonic tip (12) having plural grooves (16) formed in a smooth surface (14) thereof. Each groove (16) includes an abrasive material (24) coating the depression thereof. Rough surface areas of a workpiece projecting into the groove (16) are abraded to thereby result in a smooth workpiece surface. Once the surface roughness of the workpiece has been removed, the smooth areas (14) of the ultrasonic tip (12) are engaged, thereby preventing further abrasion of the workpiece.</p> |
