ABSTRACT:
In a machine for smoothing and polishing part-spherical surfaces on lenses, a tool and a lens are supported in contact with each other for rotation about respective axes and one of the tool and lens is driven. One of the tool and the lens is rocked about an axis which is perpendicular to its axis of rotation while the axis of the other of the tool and lens is maintained at a fixed acute angle to the plane in which the rocking occurs.
