3M 7000044819 Aluminum Oxide Lapping Disc 10 Inch Psa

Product Description

The 3M 7000044819 is an aluminum oxide lapping disc engineered for precision surface finishing applications. The aluminum oxide mineral is coated onto a 3 mil polyester film backing and bonded with a durable resin system. A pressure-sensitive adhesive (PSA) backing allows for quick mounting to compatible platens. Available in seven grades ranging from 0.05 to 60.0 micron, this disc is suited to applications requiring consistent cut rate, controlled finish, and repeatable results across production runs. The 10 inch diameter format fits standard lapping equipment used in professional finishing environments.

This disc is commonly used in fiber optic connector finishing and roll superfinishing operations. The tight particle size distribution and harder resin system compared to the 261X series deliver uniform material removal and a predictable surface finish. It is well suited for light industrial and precision manufacturing environments where surface geometry and finish quality are critical. Technicians and operators working in optical component finishing, precision grinding, and superfinishing will find this disc applicable to a range of production and maintenance tasks.

Key Features

• PSA backing for fast, secure platen mounting
• Aluminum oxide mineral on 3 mil polyester film for dimensional stability
• Tight particle distribution for consistent finish and cut rate
• Harder resin system than 261X series for improved durability and life
• Available in seven grades from 0.05 to 60.0 micron
• Suited for fiber optic finishing and roll superfinishing applications

Compatibility

Designed for use with standard PSA-compatible lapping platens and equipment used in precision surface finishing applications. Specific equipment compatibility should be verified against platen diameter and PSA interface requirements prior to installation.

Installation Notes

Mounting is performed by applying the PSA-backed disc firmly and evenly to a clean, flat platen surface, ensuring no air pockets are trapped beneath the film. Power down all equipment before disc changes. Worn or contaminated discs should be removed carefully to avoid stretching or tearing the polyester film backing. Follow facility safety procedures and equipment manufacturer guidelines when operating lapping or superfinishing machinery.
