Process breakdown for Lapping and Polishing Carbon Steel

Stage 1 lapping - 1 off part was placed centrally to a 15” pressure weight using Kemtak plus, the pressure weight was then placed into a control ring on a flat 15” Kemet Copper SP2 lapping plate and run for 15 minutes with Kemet liquid diamond 6 micron type K std being dispensed at a ratio of 2 seconds of spray every 45 seconds and cycled for a total of 15 minutes till cleaned up. The parts were then sprayed off with CO42 cleaning fluid.
