3M 7010307667 Diamond Lapping Film Disc 12 Inch Psa

Product Description

The 3M 7010307667 is a 12-inch diameter PSA-backed diamond lapping film disc designed for precision surface finishing on extremely hard materials. Built on a polyester film substrate, precisely graded diamond particles deliver a consistent, repeatable finish across a wide range of micron grades from 0.10 to 30.0 micron. The pressure-sensitive adhesive backing allows for quick, secure mounting to a flat platen without additional fasteners. This disc is suited for technicians and machinists requiring controlled material removal and uniform surface finish on hard substrates.

This diamond lapping disc is used in precision lapping and polishing applications where flatness and minimal edge rounding are critical. Typical applications include finishing ceramics, carbides, optical components, and other extremely hard materials. The disc format is well suited for bench lapping machines and flat-plate finishing setups in manufacturing, tool and die, optical, and metrology environments. The 1 1/4 inch arbor sizing accommodates standard lapping equipment configurations.

Key Features

• PSA backing for fast, secure platen mounting without additional adhesives or hardware
• Precisely graded diamond abrasive particles provide a consistent, repeatable finish
• Available in grades ranging from 0.10 to 30.0 micron for versatile finishing requirements
• Flat surface geometry minimizes edge rounding for tight tolerance work
• Long abrasive life reduces disc change frequency and increases throughput
• Polyester film backing maintains dimensional stability under load

Compatibility

Designed for use as a 12-inch diameter lapping disc on standard flat-plate lapping machines accepting a 1 1/4 inch arbor and compatible with PSA-mount platens.

Installation Notes

Installation is performed by qualified machinists or tooling technicians. Power down and fully de-energize the lapping machine before mounting or removing the disc. Ensure the platen surface is clean and free of debris before applying the PSA-backed disc to achieve full adhesive contact and a flat working surface. Follow equipment manufacturer guidelines and applicable shop safety procedures during disc changes.
