Paper Abstract

Because there are no practical commercially available bound abrasive polishing media, we are developing a bound abrasive polisher for deterministic finishing of optical glasses. Several in- house formulated polishing pellets, molded laps, and ring tools have been studied. Two experimental test beds were employed. The first involved the polishing of flat optical glass parts on single pellet and molded pellet laps. The tests were conducted on a single spindle machine. The performance of in-house manufactured laps was compared to experimental and commercial formulations obtained from industry. Compositions which polished the glass below 20 angstrom rms surface roughness were selected for additional testing. The second test bed for these formulations was the Opticam SM. Materials were molded into a ring tool geometry. Although the tools polished effectively, more work is required to control surface figure during final finishing.
