ABSTRACT:
Apparatus for polishing or grinding an optical lens through multi-directional, coplanar movement of a lens support frame relative to a polishing head. A pair of drive cams are rotated with an eccentrically mounted shaft while mounted upon orthogonal alignment braces for converting the rotation of the cam into a circular point pattern. A lens support table upstands from each cam for the support of a lens thereon in abutting relationship with a grinding or polishing head thereabove and is driven in said circular point pattern while in engagement therewith. The polishing head and cam base are likewise bidirectionally driven in orthogonal directions for permitting polishing of the entire surface area of the lens mounted thereon. In this manner lens polishing or grinding may be effected in a totally planar configuration for preventing lens slapping and edge aberation.
