Diamond Full Face Laps

Diamond Full Face Laps – Nickel Bonded Full Face Diamond Flat Lap Discs for Faceting & Flat Lapping

Professional nickel bonded full face diamond flat lap discs for faceting machines, flat lap machines, and precision lapping applications. The full face nickel bond construction covers the entire disc surface with evenly distributed diamond abrasive for consistent, uniform material removal from center to edge — ideal for faceting gem materials, flat lapping stone slabs, and precision surface finishing. Available in 6" and 8" diameters across 60–3000 grit with magnetic, PSA, and master lap backing options.

Frequently Asked Questions

  • Q: What is the difference between full face laps and standard flat lap discs?
    A: Full face laps use a nickel bond process that deposits diamond abrasive uniformly across the entire disc surface — providing consistent cutting action from center to edge with no gaps or pattern variations. Standard flat lap discs may use resin bond or dot/channel patterns that leave areas without diamond coverage. Full face laps are preferred for faceting where precise, even material removal is critical for accurate facet angles and consistent surface finish.
  • Q: What backing option should I choose for my faceting machine?
    A: Choose Master Lap backing if your faceting machine uses a master support lap (aluminium backing disc) — the full face lap screws or clips onto the master lap. Choose Magnetic backing for flat lap machines with magnetic backing plates for quick disc changes between grit stages. Choose PSA for semi-permanent mounting on PSA backing plates. Choose None (plain) for custom mounting or machines with non-standard mounting systems.
  • Q: What grit sequence should I use for faceting gemstones?
    A: A standard faceting sequence: 60–80 grit for rough pre-forming, 220–360 grit for facet shaping, 600–1200 grit for facet smoothing, 1500–3000 grit for pre-polish, then a polishing lap (tin, zinc, or felt) charged with diamond compound or cerium oxide for final mirror polish. Adjust the sequence based on gem hardness — harder materials (Mohs 8+) may require more stages.
  • Q: Can full face laps be used on a standard flat lap machine?
    A: Yes — full face laps with magnetic or PSA backing are compatible with standard flat lap machines. They are particularly effective for flat lapping stone slabs and cabochon bases where consistent flat surface removal is needed. The full face diamond coverage produces more even results than dot-pattern discs on flat surfaces.
  • Q: How long do nickel bonded full face laps last?
    A: Service life depends on the gem material hardness, grinding pressure, and water cooling consistency. On softer gem materials (Mohs 6–7) with proper water cooling and light pressure, full face laps provide excellent longevity. On very hard materials (Mohs 8–9 sapphire, ruby), sintered diamond laps may provide longer service life for high-volume faceting work.
