The Superior Performance of Diamond Lapping Film

Diamond lapping film represents a significant advancement in precision polishing technology. Unlike conventional abrasive materials, diamond lapping film features a monolayer of precisely graded diamond particles uniformly bonded to a flexible polyester film substrate. This innovative structure delivers several critical advantages for optical polishing applications.

Key Technical Advantages

• Consistent Particle Distribution: Our diamond lapping film maintains ±1μm particle size consistency, ensuring uniform material removal
• Exceptional Durability: Diamond's hardness (10 on Mohs scale) provides 3-5x longer service life than aluminum oxide alternatives
• Precision Surface Finish: Capable of achieving surface roughness (Ra) as low as 0.01μm for optical applications
• Controlled Aggressiveness: Available in grit sizes from 0.1μm to 60μm for different polishing stages

Applications in Optical Polishing

Diamond lapping film has become indispensable across various optical polishing scenarios:

Comparison with Traditional Polishing Methods

When evaluating diamond lapping film against conventional optical polishing pads, several critical differences emerge:

Material Removal Rate

Our tests show diamond lapping film achieves 20-30% faster material removal while maintaining better surface consistency compared to cerium oxide-based polishing pads. The fixed abrasive structure prevents the "glazing" effect common with loose abrasives.

Surface Quality Consistency

Traditional polishing methods often produce inconsistent results due to abrasive particle breakdown. Diamond lapping film maintains consistent performance throughout its lifespan, with less than 5% variation in surface roughness measurements across multiple workpieces.
