Abstract: A workpiece holder apparatus is disclosed for use with a surfacing tool for surfacing optical lenses having a surface of revolution especially afocal ophthalmic lenses. A workpiece holder comprises a chamber having an endwall, a sidewall and an open end, for receiving an optical lens. The chamber is connected in operation to a source of compressed air, and an air cushion is established between the endwall and the lens. There is radial clearance annularly between the edge of the sidewall and the edge of the lens. The air cushion is controlled by an annular projection protruding from the endwall, in cooperation with a facing portion of the lens. The entire workpiece holder is adapted to be fitted on a conventional fluid actuator for applying the lens against the surfacing tool.
