3M 7100113813 Aluminum Oxide Lapping Disc 4 Inch 1.0 Micron

Product Description

The 3M 7100113813 is a 4-inch diameter aluminum oxide lapping disc designed for precision polishing and surface finishing in demanding technical applications. The disc features aluminum oxide mineral coated onto a 3 mil polyester film base with a pressure-sensitive adhesive (PSA) backing for secure, tool-free mounting. The abrasive layer uses a softer resin system compared to standard aluminum oxide products, and the disc is available in a 1.0 micron grade. This combination delivers a consistent cut rate, controlled finish, and extended disc life on precision surfaces. Technicians working in fiber optic termination and electronics manufacturing will find this disc suited to their surface quality requirements.

This lapping disc is used primarily in fiber optic polishing and precision lapping operations where surface finish tolerance is critical. The tight particle size distribution ensures uniform material removal, making it appropriate for polishing fiber optic connectors and achieving smooth, flat surfaces on precision electronic components. The PSA back allows quick attachment and removal on compatible lapping fixtures and backing plates used in production or field termination environments.

Key Features

• PSA backing for fast, secure disc mounting on compatible lapping plates
• Tight particle distribution for consistent finish and repeatable cut rate
• Softer resin system than standard aluminum oxide products for controlled surface removal
• 1.0 micron grade suited for fine polishing of fiber optic connectors and precision electronic parts
• 3 mil polyester film backing provides dimensional stability during lapping operations

Compatibility

Designed for use in fiber optic connector polishing and precision lapping operations on electronic components. Compatible with lapping fixtures and backing plates that accept 4-inch PSA-backed abrasive discs.

Installation Notes

Mount the disc onto a clean, flat lapping plate or fixture by aligning the PSA backing and pressing firmly to eliminate air pockets before use. Power down or de-energize any associated equipment before handling precision optical or electronic components. Follow facility-specific ESD and cleanliness protocols when working with precision electronic assemblies. Discard discs that show loading, tearing, or uneven wear to maintain consistent surface finish results.
