3M 7010307670 Diamond Lapping Film 1.0 Micron Sheet

Product Description

The 3M 7010307670 is a diamond lapping film sheet designed for precision surface finishing on extremely hard materials. Precisely graded diamond abrasive particles are coated onto a dimensionally stable polyester film backing, producing a consistent, repeatable finish pass after pass. At 1.0 micron grade, this sheet is suited for fine finishing stages where surface quality is critical. Each sheet measures 3 inches x 6 inches and is sold individually. Typical users include optical technicians, precision machinists, fiber optic installers, and tool-and-die professionals who require controlled material removal on hardened substrates.

This lapping film is used in applications where conventional abrasives cannot hold tight tolerances or achieve the required surface finish. Common uses include lapping carbide tooling, ceramic components, optical glass, fiber optic connectors, and other hard or brittle materials. The 1.0 micron grade fits into a multi-step finishing sequence, typically following coarser lapping steps and preceding final polishing stages. It is appropriate for both bench lapping and hand-finishing work in shop or field environments.

Key Features

• 1.0 micron precisely graded diamond abrasive for fine surface finishing
• Polyester film backing provides dimensional stability during use
• Consistent particle distribution delivers repeatable finish results
• Effective on extremely hard materials including carbide, ceramic, and optical glass
• Sheet format allows use on flat lapping plates or wrapped around custom fixtures
• Part of a range spanning 0.10 to 30.0 micron grades for multi-step sequences

Compatibility

Designed for use on extremely hard materials including carbide, ceramic, glass, and similar substrates requiring precision lapping or fine surface finishing. Fits standard flat lapping plate workflows.

Installation Notes

Lapping film is typically applied by precision machinists, optical technicians, or fiber optic splice technicians using flat lapping plates, backing pads, or hand-held fixtures. Secure the sheet flat against the work surface to prevent folding or bunching during use. Apply consistent, light pressure and use an appropriate lapping fluid or dry technique as required by the substrate. Inspect the film periodically and replace when abrasive loading or wear reduces cutting performance.
