Abstract
A lens grinding apparatus which is particularly suitable for grinding aspheric lenses has a rotary shaft which carries the lens which is to be ground and which is supported for rotation about the axis of the shaft by a support structure which has a support axis parallel to but spaced from the shaft axis. A mounting structure mounts the support structure on an oscillating structure which carries a template which determines the curvature of the lens surface which is ground and which has an oscillating axis around which the template is oscillated while the mounting structure, support structure and shaft supported thereby are all oscillated also about the oscillating axis. This oscillating axis is perpendicular to the shaft axis. By turning the support structure about its support axis with respect to the mounting structure it is possible to adjust the shaft axis so that it intersects the oscillating axis.
