Abstract

An apparatus for finishing the surface of a lens mounted on one face of a lens block, having depressions for receiving pins on its other face, comprising: a tree arranged generally vertically, having an upper end and an end lower, said upper end being intended to receive a polishing tool, having a polishing surface with selected transversal and base curves, first means for rotating said shaft around its geometric axis, at a first speed, second means for moving said geometrical axis in a cylindrical plane at a speed substantially less than said first speed, means of driving pins, an arm supporting said driving pins on said depressions for receiving the pins, third means connected to said arm, to make said spikes press the surface to finish of said lens, against said polishing surface, fourth means to move said arm in a plane substantially parallel to the base curve of said polishing tool, whereby a combination of movement between said surface of the lens and said polishing surface is the sum of the rotation of said shaft about its axis, the movement of said geometric axis in a cylindrical plane and the reciprocating transverse movement of said pins.
