A 36" Rociprolap is available and is made by Covington Engineering Corp. We feel the Rociprolap is the finest lapping machine on the market. It is a precision built machine designed to eliminate the labor-intensive work of lapping and polishing. The plate revolves slowly and reciprocates 575 times per minute. The 36" Rociprolap does need to be bolted down. The lap plate is constructed of cast iron and steel. The lap plate's surface is machined flat to a very close tolerance. It also has 3/16" x 1/2" pockets on the plate to maintain fresh grit and lubrication reservoirs. It will lap rock, wood, metal, glass or any material which must be ground flat. It is extremely quiet in operation and built to industrial standards. Each unit is sold complete with a splash guard (Formica), bumper ring, motor, one set of 24 nylon ball bearings, one set of twelve steel discs, polish pad and instructions. Covington Engineering guarantees the machines for one year from the date of purchase against any defects. (This excludes the nylon thrust bearings and steel discs and leveling feet.)
