Abstract
A machine with separate motion on two axes for toroidal polishing and gring of mirrors. The axes are at 90.degree. to each other and the amplitude of motion in each direction is independently adjustable. A portion of this machine can be modified to serve as an adapter unit that fits on standard polishing machines and can be removed leaving the standard machines able to function in the normal way. A gimbal assembly and stablizer bar are used to prevent twisting between a lens and a polishing surface.
