Lapping & Polishing Graphite Test Requirements: Lap out damage to graphite seals Component/Material: Graphite seals Machine Type: Kemet 15” diamond lapping machine Lap Plate: Kemet Iron When the graphite seals were lapped on a Kemet Iron with 14 Micron Type K standard, Ra of 0.088 µm was achieved (Flatness better than 1 light band). The damage was lapped out. The graphite seals were then polished on a Kemet Iron with 3 Micron Type K standard, Ra of 0.0693 µm was achieved. If the graphite seals are only polished on 3 Micron Type K standard, it took 40 minutes to lap out the damage. Test Requirements: To lap and polish Cast Iron & Graphite mechanical seals, in a 1 stage process. Component/Material: Cast Iron & Graphite seals Machine Type: Kemet 15” diamond lapping/polishing ma
