Frequently Asked Questions

• Q: What machines use large flat lap discs?
  A: Large flat lap discs are used on production flat lap machines, industrial lapping machines, and large-format lapidary grinders. They are not compatible with standard 6"–8" hobby flat lap machines.
• Q: What grit should I use for production flat lapping?
  A: Production flat lapping typically starts with 60–120 grit metal bond for stock removal, progresses through 260–600 grit for fine grinding, and finishes with 1200–3000 grit resin bond for pre-polish.
• Q: Do large flat lap discs require special mounting hardware?
  A: Yes — large discs require a compatible machine arbor and mounting flange. Verify disc bore size and machine arbor specifications before ordering.
