3M 7010325523 Diamond Lapping Film Psa Sheet 45.0 Micron

Product Description

The 3M 7010325523 is a pressure-sensitive adhesive (PSA) diamond lapping film sheet used in precision flat lapping applications. Measuring 6 inches x 6 inches and rated at 45.0 micron grit, it uses a diamond abrasive suspended in a durable resin system engineered for added toughness and extended service life compared to standard lapping films. The PSA backing allows the sheet to mount directly to a flat lapping plate or fixture without adhesive tape or spray. Machinists, optical technicians, toolroom specialists, and precision finishing trades rely on this film for controlled stock removal and surface refinement on hard materials.

This film is suited for flat lapping of carbide tooling, ceramics, optical components, semiconductor substrates, and other hard or brittle materials requiring tight surface finish tolerances. The 45.0 micron grade is a mid-range cut that balances stock removal rate with surface finish quality. It is available in 30.0, 45.0, and 60.0 micron grades to support multi-step lapping sequences. Minimum order quantity is 25 sheets per unit of measure.

Key Features

• PSA backing mounts directly to flat lapping plates without additional adhesive
• 45.0 micron diamond abrasive grade for mid-range stock removal and surface finishing
• Stronger resin system provides added toughness and longer working life versus standard lapping film
• 6 inches x 6 inches sheet size fits common bench lapping fixtures
• Available in 30.0, 45.0, and 60.0 micron grades for multi-step finishing sequences

Compatibility

Designed for flat lapping applications on hard substrates including carbide, ceramics, and optical materials. Compatible with standard flat lapping plates that accept PSA-backed abrasive sheets.

Installation Notes

Clean and degrease the lapping plate surface before applying the PSA sheet to ensure full adhesion and prevent slippage during use. Apply firm, even pressure across the entire sheet when mounting to eliminate air pockets. Replace the sheet when abrasive performance degrades noticeably, as worn diamond film can produce inconsistent surface finishes. Dispose of used lapping film in accordance with applicable local regulations for abrasive waste.
