ABSTRACT:
A lapping machine includes upper and lower lapping wheels and a sprocket having a common centered rotational axis. A rotational drive source for at least one of the upper and lower lapping wheels provides rotational movement about the axis. At least two independently locatable gears or sprockets disposed radially exterior of the upper and lower lapping wheels rotatably carry a carrier between the upper and lower lapping wheels, in which a material carried within an opening formed in the carrier travels at least partially radially exterior of both lower and upper lapping wheels during operation of the machine.
