3M 7000044814 Aluminum Oxide Lapping Disc 8 Inch

Product Description

The 3M 7000044814 is an aluminum oxide coated abrasive disc engineered for precision lapping and fiber optic polishing applications. The aluminum oxide mineral is applied to a 3 mil polyester film backing using a softer resin system that delivers controlled, consistent material removal without aggressive surface damage. Available in 1.0 and 2.0 micron grades, this disc is designed to produce smooth, repeatable surface finishes on precision electronic components and optical terminations. The 8 inch diameter format is suitable for bench lapping fixtures and polishing machines used in production and field service environments.

This disc is used primarily in fiber optic connector polishing and precision lapping of electronic components where surface finish consistency is critical. The tight particle size distribution ensures a uniform cut rate across the full disc surface, making it well suited for high-volume polishing operations as well as controlled single-piece finishing work. Technicians working in fiber optic splicing, connector preparation, and precision electronics finishing will find this disc appropriate for their workflow.

Key Features

• Aluminum oxide mineral on 3 mil polyester film backing for dimensional stability
• Softer resin system compared to standard aluminum oxide abrasive products
• Tight particle distribution for consistent cut rate, finish quality, and disc life
• Available in 1.0 micron and 2.0 micron grades for progressive polishing sequences
• 8 inch diameter format compatible with standard lapping fixtures and polishing machines

Compatibility

Designed for use in precision lapping operations and fiber optic polishing applications requiring controlled surface finish on electronic components and optical connectors.

Installation Notes

Mount the disc securely to the lapping fixture or polishing machine platen before beginning any operation. Ensure the backing surface is clean and free of debris to prevent uneven disc seating that can affect finish consistency. Follow the equipment manufacturer's guidelines for disc attachment and machine speed settings. Dispose of used discs according to applicable workplace safety and waste handling regulations.
