The Vibrating lap is designed to abrade and polish automatically. The inertia of the heavy rock slab holds it relatively still while the lap pan vibrated underneath. This action replaces the circular rotation used by conventional lapping machines. This machine has a grooved pan for fast cutting, a bumper ring to prevent damage to the slabs. A polish pad insert into the grooved pan allows workpiece to be polished in the same pan. One thumb screw releases pan for easy cleaning. Comes complete with 110V, 60hz motor, polishing pad, bumper ring, grooved pan, instructions and guarantee. New Lower Price! This item is shipped from California.
