Polishing device for polishing optical lenses has polishing surface set in transition area between periphery of its end side and its sleeve face over which the elastic membrane engages

摘要

The polishing surface (21) of the polishing device is provided similar to a pot-shaped grinding tool in the transition area between its sleeve face (22) and the periphery of its end side (10). A rigid support body has a pressure chamber connectable to a pressurised medium source and to form a deformable polishing surface is defined by an elastic membrane (9) which engages in part over the sleeve face of the polishing tool. The support body (3) is held on a tool shaft (1) to tilt about an axis running across the longitudinal axis of the shaft.
