Grinding machine for guided or non-guided beveling or grooving of an ophthalmic lens

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.
