Spherical lapping machine

摘要

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.

主权项

1. A lapping machine for lapping generally spherical surfaces, comprising:
a lower workpiece contact portion; an upper workpiece contact portion; a mounting for a lower workpiece contact portion; a telescopic rod attached to said upper workpiece contact portion; wherein said telescopic rod is removably attached to an orbital disc; said orbital disc having an at least one aperture; wherein said telescopic rod is indirectly connected to the at least one aperture in the orbital disc and is configured to move in conjunction with the at least one aperture in said orbital disc; and wherein said at least one aperture moves in a pattern describing a roulette curve, thereby causing a workpiece to be lapped in said pattern describing a roulette curve.
