Abstract
Lapping machine for precision surfaces consists of lap tool, work cages and a driven centre wheel kinetically linked to the cages. This kinetic link is preserved regardless of the positions of the wheel and cages and a regulator is fitted which imparts the cages an additional movement of variable amplitude and speed on a cyclical basis but independent of the main movement deriving from the centre wheel, though always remaining parallel to this. Thus the lap tools and the workpieces or cages acquire a double relative planet motion in which the imaginary grid of intercepts between the machined surfaces of the workpieces and the points on the lap increases relatively in terms of frequency and uniformity.
