3M 7010360403 Aluminum Oxide Lapping Disc 12 Inch Psa

Product Description

The 3M 7010360403 is a 12-inch-diameter aluminum oxide lapping disc designed for precision surface finishing applications. The aluminum oxide mineral is coated onto a 3-mil polyester film substrate using a durable resin system with a pressure-sensitive adhesive (PSA) backing for fast, tool-free mounting. Available in seven grades ranging from 0.05 to 60.0 micron, this disc delivers a consistent cut rate, uniform finish quality, and predictable service life across a range of finishing operations. It is typically installed and used by technicians performing precision optical, mechanical, or industrial superfinishing work.

This disc is well suited to precision finishing tasks including fiber optic connector end-face finishing and roll superfinishing applications. The tight particle size distribution of the aluminum oxide mineral ensures repeatable surface quality across high-volume production runs. The PSA backing allows the disc to mount directly to a flat platen or backing pad without additional adhesives. The harder resin system compared to the 261X series provides improved abrasive retention and longer disc life under sustained cutting loads.

Key Features

• PSA backing for quick, tool-free platen mounting
• Tight particle distribution for consistent, repeatable finish results
• Harder resin system than 261X series for improved abrasive retention
• Consistent cut rate, finish quality, and disc life across grades
• Available in seven micron grades from 0.05 to 60.0 micron
• Also available in sheet and roll form factors

Compatibility

Designed for use in fiber optic finishing and roll superfinishing applications requiring a PSA-backed, polyester-film lapping disc with aluminum oxide abrasive.

Installation Notes

This disc is installed by trade technicians and production finishing specialists onto a compatible flat platen or backing pad. Ensure the platen surface is clean and free of debris before applying the PSA-backed disc to achieve full adhesion and prevent disc slippage during use. Remove the disc carefully after use to avoid leaving adhesive residue on the platen. Follow the equipment manufacturer's guidelines for rotational speed and applied pressure for the specific micron grade in use.
