ABSTRACT:
A lens grinding machine includes a grinding tool mounted on a tool support, and a lens holder mounted in a tailstock assembly. The lens is positioned for grinding by advancing the tailstock assembly into engagement with the tool support. A push-back member carried by a housing of the tailstock assembly is actuated to displace the tailstock housing to a predetermined spacing from the tool reference axis. A dial carried by the tailstock housing and operably connected to the lens holder is rotated to bring a desired lens thickness-related value on one scale into alignment with a lens diopter-related value on an adjacent scale, whereupon a precise grinding position of the lens is attained.
