3M 7100036697 Aluminum Oxide Lapping Disc 4 Inch Psa

Product Description

The 3M 7100036697 is an aluminum oxide lapping disc engineered for precision surface finishing in demanding industrial and fiber optic applications. The disc features aluminum oxide mineral coated onto a 3 mil polyester film substrate using a durable resin system, and is backed with a pressure-sensitive adhesive (PSA) for secure, tool-compatible mounting. Available in seven grades ranging from 0.05 to 60.0 micron, this disc delivers consistent cut rate, finish quality, and service life across a wide range of abrasive finishing tasks. It is designed for use by technicians and skilled tradespeople who require repeatable, precise material removal.

This lapping disc is well suited for fiber optic connector end-face finishing and roll superfinishing operations where tight surface geometry tolerances are required. The PSA backing makes it compatible with flat-lapping fixtures and rotary polishing equipment used in fiber optic termination and precision component finishing workflows. The disc format is available alongside sheet and roll configurations, allowing integration into both manual and automated finishing processes common in telecommunications, manufacturing, and precision assembly environments.

Key Features

• PSA backing provides secure adhesion to lapping fixtures and polishing pads without adhesive mess
• Tight particle size distribution ensures consistent finish and repeatable material removal
• Harder resin system compared to 261X product family for improved durability and cut consistency
• Available in seven grades from 0.05 to 60.0 micron to cover rough lapping through final polish
• Compatible with disc, sheet, and roll formats for flexible process integration
• Consistent cut rate and service life reduce process variability in high-tolerance finishing

Compatibility

Designed for use in fiber optic finishing and roll superfinishing applications. Compatible with standard flat-lapping and rotary polishing equipment that accepts PSA-backed abrasive discs at 4 inch diameter.

Installation Notes

Installation and use of PSA-backed lapping discs should be performed by qualified technicians familiar with precision abrasive finishing procedures. Ensure the backing plate or lapping fixture surface is clean and free of debris before applying the disc to achieve full adhesive contact. Power down any rotary equipment before mounting or removing the disc. Follow equipment manufacturer guidelines for speed and pressure settings appropriate to the micron grade selected.
