The Rociprolap is built to industrial standards, all cast iron and steel construction. The crank shaft is 1 1/8" in diameter. The lap plate rides on ball bearings and is actuated by the crank shaft which has a stroke of 7/16" from a 1/3 horse motor. The lap plates are made of fine grain cast iron and machined flat to a very close tolerance. The Rociprolap is capable of lapping to within three light bands of helium light or millionths of an inch of flatness.

Without a doubt, the Rociprolap is the most sturdy, dependable, and accurate lapping machine for the money.  Still priced well below other products, this machine will continue to serve you for many, many years after purchase.  You will experience that same thrill of satisfaction every time you turn in on.

The Rociprolap is a precision built machine, designed to eliminate the manual work of lapping and polishing.  It is balanced, therefore it does not have to be bolted down.  This machine operates as its name implies, the lap plate revolves slowly, about 4 rpm, and reciprocates 575 times per minute simultaneously. It is extremely quiet in operation and very economical in the use of grinding and polishing compounds.
