Collection: Precision Lapping Film Disc

Achieve mirror-like finishes or sub-micron precision across industries like electronics, optics, and tool sharpening with optimized lapping films. Explore the types, applications, and selection criteria below.

What is Lapping?

Lapping is a precision process where surfaces are polished using abrasives between two substrates. Ideal for achieving flatness, smoothness, or specific textures, it’s performed manually or with lapping machines.

Types of Lapping Films

1. Aluminum Oxide Lapping Film

• Best For: General-purpose finishing of metals, ceramics, and composites.

• Features: Moderate aggressiveness, ideal for lapidary tasks like polishing gemstones or refining metal surfaces.

• Linked Product: Aluminum Oxide Films

2. Silicon Carbide Lapping Film

• Best For: Hard materials like glass, stone, and hardened steel.

• Features: Sharper than aluminum oxide, perfect for rapid material removal.

• Linked Product: Silicon Carbide Films

3. Cerium Oxide Lapping Film

• Best For: Ultra-fine polishing of optics, semiconductors, and fiber-optic components.

• Features: Delivers high-gloss finishes with nano-grade particles.

• Linked Product: Cerium Oxide Films

4. Diamond Lapping Film Disc

• Best For: Extreme-hardness materials like carbide, sapphire, and advanced ceramics.

• Features: Unmatched durability for critical tasks like hard drive head polishing.

• Linked Product: Diamond Films

Key Applications

• Electronics: Polish fiber-optic connectors or semiconductor wafers.

• Tool Sharpening: Sharpen blades with diamond lapping films.

• Lapidary & Optics: Refine gemstones or optical lenses.

• Industrial Manufacturing: Finish ceramic components or metal alloys.

Why Choose Lapping Films?

• Precision Control: Adjust grits (30µ–0.1µ) for tasks from shaping to polishing.

• Versatility: Use flexible discs for curves or rigid laps for flatness.

• Cost Efficiency: Reusable films reduce waste vs. traditional abrasives like silicon carbide.

Tips for Effective Lapping

1. Match Grit to Task: Start with coarse abrasives for shaping, then switch to fine grits.

2. Use Lubrication: Enhance performance with coolants.

3. Pair with Tools: Combine films with lapping machines or hand tools.

Final Recommendation

• Beginners: Start with aluminum oxide or silicon carbide for versatility.

• Advanced Users: Opt for diamond films for extreme precision.
