3M 7000044835 Diamond Lapping Film Disc 8 Inch Psa

Product Description

The 3M 7000044835 is a PSA-backed diamond lapping film disc designed for precision surface finishing on extremely hard materials. Built on a stable polyester film base, it carries precisely graded diamond abrasive particles that deliver a consistent, repeatable finish across each use. The pressure-sensitive adhesive backing simplifies disc mounting to flat platens and backing pads. Available in grades ranging from 0.10 to 30.0 micron, this disc suits applications where tight surface finish tolerances are required. It is used in manufacturing, optical, and precision machining environments by skilled technicians and machinists who need controlled, uniform material removal.

This diamond lapping film disc is suited for lapping and polishing extremely hard materials including ceramics, carbides, glass, and hardened metals. The PSA backing allows quick application to rigid or semi-rigid flat platens. It is commonly used in precision grinding and finishing operations where flat surface geometry and low edge rounding are critical requirements. The disc format makes it a practical choice for bench lapping machines and rotary lapping equipment used in production and toolroom settings.

Key Features

• PSA backing for fast, secure platen mounting
• Precisely graded diamond particles provide a consistent, repeatable finish
• Flat surface geometry with low edge rounding
• Fast cut rate supports increased throughput
• Long abrasive life reduces frequency of disc changes
• Polyester film base maintains dimensional stability during use

Compatibility

Designed as an OEM-style replacement disc for flat lapping and polishing applications requiring PSA-mounted diamond abrasive film on standard rotary or bench lapping equipment.

Installation Notes

Installation is performed by machinists or precision finishing technicians. Ensure the platen surface is clean, dry, and free of debris before applying the PSA-backed disc to prevent air pockets or uneven adhesion. Peel and apply with firm, even pressure from the center outward. Remove and replace the disc when cut rate noticeably decreases or surface finish consistency degrades.
