Abstract
A lapping machine that can reproduce novel lapping patterns for generally spherical workpieces. The lapping machine replicates the motions commonly used in manual lapping, but with full reproducibility. The desired patterns of lapping are representative of roulette curves, and the present disclosure describes a novel means to produce roulette curve lapping of spherical workpieces by machine. The lapping machine may utilize a free rolling spherical lap arrangement in the lower unit and a telescopic rod and spherical lap in an upper unit. Different tools for holding the workpiece allow for easy adjustment to a variety of work piece sizes and shapes.
