Apparatus for generating lens surfaces

摘要

An apparatus for simultaneously machining a plurality of lens blanks to provide a lens surface on each blank corresponding to a selected lens prescription includes a tool support assembly and a lens blank assembly. The tool support assembly movably supports at least one tool. The lens blank support assembly includes a plurality of lens blank retainers for supporting a plurality of lens blanks. The tool support assembly and the lens support assembly move relative to each other such that the tool alternatingly engages each of the plurality of lens blanks for machining an individual lens prescription in a raster-like manner on each of the plurality of lens blanks.
