Abstract
A machine for grinding ophthalmic lenses includes a motor driven grinding wheel, a swinging head frame for holding ophthalmic lens and rotating the lenses into and out of contact with the grinding wheel, and a veneer positively connected to the swinging head frame by a positive linkage to prevent separation of the swinging head frame from the controlling veneer and thereby avoid the introduction of errors into the position of the lens relative to the control position of the veneer.
