Abstract: Method for renewing grinding wheel surfaces in a machine for grinding ophtalmic lenses, comprising one or more diamond wheels (2, 3, 4, 5), gripping means (7, 8) capable of receiving an ophtalmic lense, and control means. Once wheel wear is detected, the surface is renewed using an abrasive disk (9) fitted to the grinding machine in place of a lense in the gripping means. The invention also concerns a disk (9) for carrying out said method, with at least the peripheral surface consisting of abrasive material and having, at its centre, means for engagement with the machine's gripping means (7, 8). A machine for grinding ophtalmic lenses and carrying out said method is also described.
