    These Rociprolap® machines are a precision built machine designed to eliminate the labor-intensive work of lapping and polishing.  This machine operates as its name implies, the lap plate revolves slowly and reciprocates 575 times per minute simultaneously.  It is balanced and does not need to be bolted down.  Extremely quiet in operation and built to industrial standards, all cast iron and steel construction.  The lap plate’s surface is machined flat to a very close tolerance, capable of lapping to millionths of an inch in flatness.  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.  It is especially suited to lap compressor valves.  Each unit is sold complete with Formica splash guard, bumper ring, 1/3 hp motor, one set of 12 nylon ball bearings, one set of 6 steel discs, and a complete set of instructions.  Covington Engineering Guarantees the machines for one year from date of purchase against any defects.  *This excludes the nylon thrust bearings and steel disks.
