Polishing method for machining an optical surface of an optical lens and polishing tools suitable therefor

Abstract

A polishing method for machining an optical surface of an optical lens uses a polishing wheel which has a wheel axis and a polishing face. The polishing wheel is moved in relation to the lens over the surface of the latter along a spiral machining path. The polishing wheel is rotated about the wheel axis, and is (simultaneously) rotated about an axis of rotation oriented perpendicularly to the wheel axis. The rotational speed of the polishing wheel about the wheel axis and/or the axis of rotation is reduced at the spiral center of the movement path. A workpiece fixture for receiving an optical lens stands opposite the polishing wheel, with the workpiece fixture and the polishing wheel being mounted movably in relation to one another along a spiral movement path. The rotational speed of the wheel axis can be coupled kinematically to the rotational speed of the axis of rotation.
