3M 7000000283 Lapping Film 261X 9.0 Micron 8.5x11 Inches

Product Description

The 3M 7000000283 is a precision lapping film sheet designed for controlled material removal and ultra-fine surface finishing across a range of substrates. Part of the 3M 261X series, this sheet is coated with precisely graded aluminum oxide abrasive particles at a 9.0 micron grade, applied to a 3 mil polyester film backing. The uniform particle distribution produces consistent, repeatable finishes with minimal surface variation. Measuring 8.5 inches x 11 inches, each sheet is suited for hand lapping, fixture-guided lapping, and machine finishing applications where tight surface tolerances are required.

This lapping film is used in precision finishing operations across fiber optic connector polishing, tool and die work, optical component preparation, and fine surface conditioning of metal, ceramic, and composite substrates. The 9.0 micron grade is typically used in intermediate finishing stages, removing scratches and surface irregularities before transitioning to finer grades. Technicians in telecommunications, manufacturing, and optical assembly regularly specify this product for consistent results in controlled finishing sequences.

Key Features

• 9.0 micron precisely graded aluminum oxide abrasive for uniform material removal
• 3 mil polyester film backing provides dimensional stability and conformability
• 8.5 inch x 11 inch sheet format compatible with hand and fixture lapping setups
• Produces uniform finishes across metal, ceramic, and composite substrates
• Part of the 261X series, available in multiple micron grades for full finishing sequences

Compatibility

Designed as a general-purpose precision lapping film sheet for use in hand lapping, machine-guided lapping, and polishing fixtures requiring a 9.0 micron aluminum oxide abrasive on standard 8.5 inch x 11 inch sheet stock.

Installation Notes

Lapping film sheets are installed by technicians and precision finishing specialists using appropriate lapping fixtures, backing plates, or hand blocks suited to the substrate and geometry. Ensure the work surface and backing plate are clean and free of debris before mounting the sheet to prevent uneven abrasion or film tearing. Follow the finishing sequence from coarser to finer micron grades to achieve the target surface finish. Handle sheets by the edges to avoid contaminating the abrasive surface.
