3M 7000021271 Lapping Film 262X 1.0 Micron Roll

Product Description

The 3M 7000021271 is an aluminum oxide lapping film designed for precision polishing and surface finishing applications. 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 finish. This film is supplied in a 3-inch wide, 600-foot roll at a 1.0 micron grade, making it suited for fine polishing work where tight surface tolerance is required. Technicians and precision finishing specialists use this product in automated and hand-lapping setups alike.

This lapping film is used primarily in fiber optic connector polishing and precision electronic component finishing. The 1.0 micron grade targets final-stage polishing steps where surface roughness must be minimized. It is also applicable to precision lapping operations across electronics manufacturing and optical assembly environments. The roll format supports both machine-fed and manual fixture-based processes common in production and field service settings.

Key Features

• Aluminum oxide abrasive mineral for consistent cut rate and surface finish
• Softer resin bond system allows controlled, gentle material removal
• 3 mil polyester film backing provides dimensional stability during lapping
• 1.0 micron grade suited for fine and final-stage polishing steps
• Roll format: 3 inches wide x 600 feet for extended production runs
• Compatible with fiber optic polishing and precision electronic part finishing

Compatibility

Designed for use in fiber optic connector polishing fixtures and precision lapping operations involving electronic components where a 1.0 micron aluminum oxide film is specified.

Installation Notes

Installation and use of lapping film is typically performed by precision finishing technicians or fiber optic splicing and termination specialists. Ensure the polishing fixture or lapping plate is clean and free of debris before loading the film to avoid scratching the work surface. Advance or replace the film section regularly to maintain consistent abrasive performance. Follow equipment manufacturer guidelines for film tensioning and feed rate.
