3M 7000000288 Lapping Film 1.0 Micron 8.5x11 in Sheet

Product Description

The 3M 7000000288 is a precision lapping film sheet engineered for fine polishing and surface finishing applications. It features aluminum oxide mineral coated onto a 3 mil polyester film substrate using a softer resin bonding system. The sheet measures 8.5 inches x 11 inches and is graded at 1.0 micron, delivering consistent, controlled material removal at the finest end of the abrasive spectrum. This product is designed for use by technicians and skilled trades professionals working in precision electronics manufacturing, fiber optic termination, and similar high-tolerance finishing environments.

This lapping film is suited for polishing fiber optic connectors and precision electronic components where surface finish quality is critical. The 1.0 micron grade is appropriate for final-stage polishing passes where a smooth, uniform surface is required. It is also used in precision lapping operations across optical and electronic component production. Each sheet is sold individually and is intended for single-use or short-run applications to maintain consistent abrasive performance.

Key Features

• Aluminum oxide mineral on 3 mil polyester film for dimensional stability during lapping
• 1.0 micron abrasive grade for fine, controlled surface finishing
• Softer resin system allows consistent cutting action on delicate precision parts
• 8.5 inch x 11 inch sheet size fits standard flat lapping fixtures and hand polishing
• Suited for fiber optic connector polishing and precision electronic surface preparation

Compatibility

Designed as an OEM-style replacement lapping film sheet for use in precision fiber optic polishing and electronic component finishing operations requiring a 1.0 micron aluminum oxide abrasive on polyester film.

Installation Notes

This product is installed by technicians performing precision polishing or lapping operations. Secure the sheet flat against a lapping plate or backing surface before use to prevent wrinkling or uneven abrasion. Inspect the film surface prior to each use and replace the sheet if the abrasive layer shows signs of loading or wear. Follow facility safety guidelines for handling abrasive films, including appropriate eye protection.
