3M 7000036208 Diamond Lapping Film Disc 8 Inch Psa

Product Description

The 3M 7000036208 is a PSA-backed diamond lapping film disc measuring 8 inches in diameter, designed for precision finishing on extremely hard materials. This disc uses precisely graded diamond abrasive particles coated onto a polyester film substrate, delivering a consistent and repeatable surface finish. Available in grades ranging from 0.10 to 30.0 micron, it is suited for applications demanding tight surface tolerances. The pressure-sensitive adhesive backing allows fast, secure disc changes on compatible lapping fixtures. Technicians working with ceramics, carbide, optical components, and other hard substrates rely on this disc for controlled material removal and uniform finish quality.

This diamond lapping film disc is used in precision lapping and polishing operations across industries including optical, semiconductor, aerospace, and precision tooling. It performs well on flat lapping surfaces and is engineered to minimize edge rounding, making it appropriate for work where geometry control is critical. The long abrasive life of the diamond coating reduces the frequency of disc changes, improving throughput in production and field service environments.

Key Features

• PSA backing for quick, secure mounting on lapping plates and fixtures
• Precisely graded diamond particles for consistent, repeatable finish quality
• Available in micron grades from 0.10 to 30.0 micron to match application requirements
• Flat surface geometry and low edge rounding for tight dimensional control
• Long abrasive life reduces disc change frequency and increases throughput
• Polyester film substrate provides dimensional stability during use

Compatibility

Designed for use on flat lapping machines and fixtures that accept 8-inch PSA-backed abrasive discs, suitable for lapping extremely hard materials including ceramics, carbide, and optical glass.

Installation Notes

Installation is performed by qualified technicians familiar with precision lapping equipment. Ensure the lapping plate surface is clean and free of debris before applying the PSA-backed disc. Peel and apply firmly to the plate, working from the center outward to eliminate air pockets. Power down and lock out lapping equipment before disc changes in accordance with applicable facility safety procedures.
