ABSTRACT:
A grinding and polishing tool includes a pair of opposed grinding wheels for grinding or polishing simultaneously each of a plurality of discs located therebetween. Outer pulley wheels on a collar in cooperation with an inner pulley wheel support the discs peripherally and permit both rotation about and translation along the respective rotational axis of each disc in response to forces imposed by the grinding wheels. A uniform thickness of the discs is achieved by employing the discs themselves randomly distributed about the collar as spacers between the non-resilient grinding wheels to initially contact and grind the thicker discs until all discs are of equal thickness. Gimbal mounting one grinding wheel permits self-alignment thereof in a parallel relationship with the other grinding wheel to obtain parallel ground or polished surfaces on each disc.
