ABSTRACT:
A grinding machine for grinding eyeglass lenses includes at least one grinding wheel rotatably mounted on a chassis. A carriage is pivoted to the chassis to pivot about an axis parallel to the rotation axis of the grinding wheel. A support spindle is rotatably mounted on the carriage to rotate about an axis also parallel to the rotation axis of the grinding wheel and which is adapted to receive axially the lens to be ground and a template. A feeler in vertical alignment with the template is mounted on the chassis so that it is movable transversely relative to the pivot axis of the carriage. The feeler comprises a rigid pad and a tactile sensor appropriately attached to the rigid pad, at the surface thereof.
