3M 7000044867 Aluminum Oxide Lapping Film Disc 5 in

Product Description

The 3M 7000044867 is a 5-inch diameter aluminum oxide lapping film disc engineered for precision surface finishing. It features tightly graded aluminum oxide abrasive particles coated onto a 3-mil polyester film backing. This construction delivers a consistent cut rate, uniform finish, and repeatable performance across production runs. Available in 0.30, 3.0, 5.0, 9.0, 12.0, and 30.0 micron grades, the disc covers a wide range of finishing requirements from coarse stock removal to fine polishing. It is used by technicians and tradespeople who need controlled, repeatable surface quality on precision components.

This lapping film disc is suited for finishing and polishing operations on a variety of substrates including metals, ceramics, composites, and optical materials. Typical applications include fiber optic connector polishing, precision tool finishing, and surface preparation on tight-tolerance components. The 5-inch diameter format is compatible with standard disc-type lapping and polishing equipment used in both shop and field service environments.

Key Features

• Tight particle size distribution for consistent finish quality across the disc surface
• Uniform cut rate and extended disc life reduce process variation
• 3-mil polyester film backing provides dimensional stability during use
• Available in multiple micron grades: 0.30, 3.0, 5.0, 9.0, 12.0, and 30.0 micron
• Performs on a wide range of substrates including metal, ceramic, and composite materials

Compatibility

Designed for use with standard 5-inch disc lapping and polishing equipment. Compatible with a broad range of substrates as a precision surface finishing consumable.

Installation Notes

Lapping film discs are installed and replaced by technicians performing precision surface finishing or polishing operations. Ensure the backing plate or platen is clean and free of debris before mounting the disc to prevent uneven abrasion. Follow equipment manufacturer guidelines for disc attachment and rotational speed. Inspect the disc for wear or loading and replace as needed to maintain finish consistency.
