ABSTRACT:
A method of checking that a lens suits an eyeglass frame uses the lens grinding machine itself. The lens to be ground is mounted on a support shaft and moved into contact with the grinding wheel with the latter stationary. The support shaft is rotated stepwise until the lens to be ground has rotated through one complete turn. A check is carried out to determine whether a feeler associated with a template is operated thereby during such rotation. The invention finds an application in grinding machines used to trim eyeglass lenses.
