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