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.
