Polishing disc for a tool for the fine machining of optically active surfaces particularly on spectacle lenses and method for its production |
摘要 |
A polishing disc for a tool for the fine machining of optically active surfaces, particularly on spectacle lenses as workpieces, comprises a main body which has a center axis and on which there is fixed an intermediate layer which is softer than the main body and on which a polishing agent carrier rests. The intermediate layer has, with respect to the center axis, a radial inner region of substantially constant axial thickness and an adjoining radial outer region. The latter is formed or is fixed to the main body in a particular way so as to prevent the edge of the polishing disc from being imprinted on the machined surface of the workpiece in the form of very fine, scratch-like microstructures. Also proposed is a simple method which can be used to produce such a polishing disc. |
