Abstract (en)
[origin: EP1698432A2] A polishing foil (18) has an aperture (20) in a center area. During processing, the aperture causes balanced pressure and supplies a liquid polishing agent from inside a layer of foam material. This produces better washing and cooling of polishing disk areas that are otherwise put at a disadvantage. An independent claim is also included for a tool for fine machining of optically active surfaces on spectacle lenses.
