Frequently Asked Questions

  • Q: What is aluminium oxide lapping film used for?
    A: Aluminium oxide lapping film is used for precision fine finishing and polishing of glass, metal, fiber optic connectors, and gemstones. The uniform Al₂O₃ abrasive coating delivers consistent, controlled surface finishing at fine grit stages.
  • Q: How does aluminium oxide lapping film compare to diamond lapping film?
    A: Diamond lapping film cuts harder materials more aggressively and lasts longer. Aluminium oxide lapping film is better suited for fine finishing on glass, soft metals, and fiber optics where a gentler abrasive action is needed. Use diamond film for harder materials; use aluminium oxide for fine finishing on softer materials.
