6 in 0.5μm Cerium Oxide Lapping Film Discs, 10-Pack for Optical Glass & Quartz Gemstones

The 6 in 0.5μm Cerium Oxide Lapping Film Discs (10-Pack) are engineered specifically to produce an optical-grade, pit-free finish on glass, quartz, agate, and various silicate gemstones.

Key Features

• High-Purity Cerium Oxide (0.5μm): Chemically reactive polishing action creates rapid optical clears and deep reflections on quartz and silica-rich materials.
• Standard 6-Inch Diameter: Direct fit for standard 6-inch flat laps, faceting master laps, and metallurgical finishing machines.
• Uniform Mylar Film Backing: High-precision polyester film backing eliminates surface ripples, disc warping, and edge curling under wet conditions.
• Cost-Effective 10-Pack: Multi-piece pack ensures continuous workflow without unexpected interruptions during final facet polish.

Recommended Applications

• Optical glass polishing, prisms, lens beveling, and scientific flat mirror work.
• Final polishing on quartz group minerals (amethyst, citrine, smoky quartz, rose quartz, and chalcedony/agate).
• Fiber optic connector end polishing and precision telecommunication maintenance.

Operating Guidelines

• Mount securely to a clean flat master lap or acrylic backing disc using light water tension or PSA backing.
• Always operate wet with clean water to prevent thermal shock and abrasive glazing.
• Run at low speeds (150–400 RPM) using light hand touch to prevent rounding gemstone facet edges.
