    摘要: In a grinding machine for beveling or grooving an ophthalmic lens in guided or non-guided modes, the support shaft for the grinding tool is mounted to be movable relative to that carrying the ophthalmic lens to be processed. Associated with it are displacement means adapted to procure its guided displacement parallel to its axis. Between this mobile support shaft and the associated displacement means are selectively engageable coupling means. These procure either axial displacement of the mobile support shaft by virtue of the drive action of said displacement means or disengagement relative to said displacement means at least.

    摘要: A machine for grinding ophthalmic lenses comprises a frame and a support to which an ophthalmic lens to be processed may be attached pivoted to the frame about an axis parallel to the axis of the grinding tool. A counterweight on the support is movable relative to the frame in a direction orthogonal to the pivot axis. A drive device controls movement of the counterweight. A guide cam is disposed on the path of movement of the counterweight. The machine may be used for trimming and/or bevelling or grooving an ophthalmic lens.

    摘要: 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.
