Abstract
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.
