Process for Lapping and Polishing Resin

Stage 1: 10x resin squares were placed together and held in a profiled work holder and a dycem faced hand weight were placed on top. The parts were run on a flat cast Iron plate with kemox 0-800s being applied till the face had cleaned up. This stage was repeated on the other 5 sides of the resin, then cleaned with Co42 after the 6 cycles.

Stage 2: The 10x matt lapped resin squares were placed together and held in a profiled work holder and a dycem faced hand weight were placed on top. The parts were run on a ASFL polishing cloth with 3 micron type k being dispensed at a ratio of 2 seconds of spray every 45 seconds. The cycle time for each of the 6 sides were 10 minutes. Cleaned with Co42 after processing.
