Abstract
An apparatus and method for polishing a rotationally symmetric object such as a glass ball lens. The apparatus includes first and second plates for securing a plurality of glass ball lenses therebetween. The plates are secured to one another and the entire apparatus is pressed against a polishing pad in order to flatten a portion of the surface of the lenses. The apparatus also serves to maintain the orientation of the rotationally symmetric objects, so that they may be easily operated upon by future processing steps.
