Abstract
An attachment system for a lens surfacing and polishing pad adapted for use with a lapping tool is described. The lapping tool includes a curved surface having a metallic surface disposed on at least a portion thereof. The pad has a configuration conforming to the curved surface of the lapping tool and includes a first abrasive surface and a second metallic surface. The metallic surface of the lapping tool may be magnetized, either selectively or permanently, permitting the metallic substrate surface to adhere thereto, thus removably fastening the pad to the lapping tool. Alternatively, the metallic surface of the pad may be magnetized, permitting the metallic surface of the lapping tool to adhere thereto, thus removably fastening the pad to the lapping tool.
