Patent ID: 8684525

Claim:
A machining method for a spectacle lens blank, in which a block piece for holding and supporting the spectacle lens blank in a machine tool is connected to a first side of the spectacle lens blank by a connecting material, comprising the steps of: a) defining a cavity between the block piece and the first side using at least a block ring of a mounting machine, wherein the block ring has an inside diameter, Dd or Ds, and is positioned so as to contact the first side, b) filling the connecting material into the cavity or providing connecting material in the cavity and said connecting material is subsequently cured such that the block piece is connected to the first side of the spectacle lens blank by the connecting material, c) removing the spectacle lens blank that has been connected to the block piece by the connecting material from the mounting machine and placing the spectacle lens blank in a milling machine and/or lathe or grinding machine with the block piece which has been connected using the connecting material, wherein the spectacle lens blank is supported by the connecting material on the first side across an outside diameter of the connecting material, Dv, which is equal to the inside diameter, Dd or Ds, of the blocking ring and d) reducing the blank and the connecting material in size in the milling machine, lathe or grinding machine during one of the subsequent machining processes.
