3M 7100056199 Lapping Film Sheet 2.0 Micron 8.5x11 in

Product Description

The 3M 7100056199 is an aluminum oxide lapping film sheet designed for precision surface finishing and fiber optic polishing. The abrasive mineral is coated onto a 3 mil polyester film backing using a softer resin system, which allows controlled material removal and consistent surface quality. Each sheet measures 8.5 inches x 11 inches and is graded at 2.0 micron, making it suitable for fine finishing stages where tight surface tolerances are required. Technicians and precision assembly specialists use this film when working on fiber optic connectors and sensitive electronic components.

This lapping film is used in both fiber optic polishing and general precision lapping applications. It is well suited for finishing end-faces on fiber optic connectors, as well as achieving smooth, uniform surfaces on precision electronic parts in production or repair environments. The 2.0 micron grade fits into a progressive polishing sequence, typically following coarser abrasive steps and preceding finer finishing films where required by the process specification.

Key Features

• Aluminum oxide abrasive mineral for consistent, controlled cutting action
• Softer resin bond system allows smooth, uniform material removal on delicate surfaces
• 3 mil polyester film backing provides dimensional stability during lapping
• 2.0 micron grade suited for intermediate to fine finishing stages
• Sheet format at 8.5 inches x 11 inches fits standard polishing fixtures and manual processes
• Applicable to fiber optic connector polishing and precision electronic part finishing

Compatibility

Designed for use in precision lapping and fiber optic polishing operations where a 2.0 micron aluminum oxide abrasive film on polyester backing is specified.

Installation Notes

This film is handled and used by precision assembly technicians and fiber optic splicing professionals, not typically installed in a fixed mechanical assembly. Ensure the work surface and backing plate are clean and free of debris before placing the lapping film to prevent scratching or uneven material removal. Follow the polishing process sequence specified for your connector type or component, and replace film sheets when abrasive loading or surface wear is visible. Dispose of used sheets according to local waste handling guidelines for abrasive materials.
