Covington 30 Inch RociprolapFlat Lap Machine Covington's Rociprolap® is a precision built Flat Lap Machine designed to eliminate the labor-intensive work of lapping and polishing. The lap plate revolves slowly and reciprocates 575 times per minute. It is balanced and does not need to be bolted down. This unit is extremely quiet in operation and built to industrial standards. This heavy duty unit is constructed entirely of cast iron and steel. The lap plate's surface is machined flat to a very close tolerance. The lap plate also has 3/16" x 1/2" pockets to maintain fresh grit and lubrication reservoirs. The Rociprolap® will lap rock, wood, metal, glass, or any material which must be ground flat. Each unit is sold complete with a splash guard, bumper ring, motor, one set of twelve 5/8" nylon ball bearings, one set of 6 steel discs, polish pad, and instructions.
