DEVICE FOR RECALIBRATING A MACHINE FOR GRINDING OPHTHALMIC GLASSES

摘要

In a method employed by the device, the distance between a shaft (14) of a grinding wheel (13) and a shaft (5) carrying a finished glass (7) in contact with the grinding wheel, is measured by means of a microprocessor (18) controlling a shifting device (11), by bringing a tracer member (9) in contact with a template (8) mounted on the shaft (5), a standard disk (20) being mounted on the shaft (14) coaxial with the grinding wheel (13) for measuring the distance between the shaft (14) and the shaft (5) by bringing the standard disk in contact with the finished glass.
