3M 7000044743 Diamond Lapping Film Disc 1.0 Micron 5 in

Product Description

The 3M 7000044743 is a diamond lapping film disc engineered for precision surface finishing and material removal in tight-tolerance applications. Tightly graded diamond mineral is precision coated onto a dimensionally stable polyester film backing, delivering consistent cut rates and superior surface finishes from first use through the life of the disc. The disc measures 5 inches in diameter and carries a 1.0 micron abrasive grade, making it well-suited for ultra-fine finishing work where surface quality and flatness are critical. Installation and use is handled by technicians and machinists working in optical, electronic, and precision mechanical applications.

This lapping film disc is used in precision finishing operations where controlled material removal and repeatable surface quality are required. Typical applications include lapping fiber optic connectors, ceramic components, hardened metals, and other hard or brittle materials. The 5-inch diameter and 1.0 micron grade position this disc for final or near-final finishing stages. It is available with or without a PSA backing, allowing it to be used on compatible rotary or hand-lapping platens and fixtures.

Key Features

• 1.0 micron tightly graded diamond mineral for precise, consistent abrasive action
• Precision coated on a polyester film backing for dimensional stability and flatness
• Consistent processing and surface finish performance throughout the full product life
• Available with or without PSA backing for flexible mounting options
• 5-inch diameter disc format compatible with standard lapping fixtures and platens

Compatibility

Designed as an OEM-style replacement or direct-use lapping disc for standard 5-inch rotary lapping platens and hand-lapping fixtures used in precision finishing applications.

Installation Notes

Lapping film discs of this type are installed by precision finishing technicians or machinists. Before mounting, ensure the platen surface is clean and free of debris that could cause uneven film seating. For PSA-backed versions, align the disc carefully before pressing into place, as repositioning can compromise adhesion. Follow the equipment manufacturer guidelines for rotational speed and applied pressure to avoid tearing the film backing.
