3M 7010365431 Diamond Psa Disc 8 Inch Lapping

Product Description

The 3M 7010365431 is a Diamond Metal Bond PSA disc engineered for precision lapping, finishing, and polishing applications. Micron-graded diamond mineral is bonded to a brass plate using a metal bond process, producing a cutting surface that removes material at a controlled, consistent rate while delivering fine surface finishes. The pressure-sensitive adhesive backing allows fast, secure attachment to a machine platen or support plate without mechanical fasteners. At 8 inches in diameter and 0.07 inches thick, this disc fits standard lapping machine setups used in machine shops, toolrooms, and precision fabrication environments. Installation and use are handled by machinists, tool and die specialists, and precision grinding technicians.

This disc is designed for lapping and related flat-surface finishing operations where tight tolerances and smooth surface profiles are required. The evenly spaced diamond mineral cuts aggressively enough to remove workpiece imperfections while still achieving the fine finishes demanded by close-tolerance work. It is suitable for use on a variety of substrates, including ceramic, carbide, and other hard materials commonly encountered in precision machining and metrology applications.

Key Features

• Micron-graded diamond mineral provides sharp cutting action with fine finishing results
• Metal bond construction adheres diamond abrasive to a brass plate for consistent, controlled material removal
• Pressure-sensitive adhesive backing enables fast, tool-free mounting to machine platens or support plates
• Evenly spaced mineral pattern removes workpiece imperfections at a uniform rate
• Compatible with a variety of substrates including ceramic and other hard materials
• Suited for lapping, finishing, and polishing operations

Compatibility

Designed for use on standard lapping machines and support plates that accept 8-inch PSA-backed abrasive discs; suitable for use on ceramic, carbide, and other hard substrates in precision machining and finishing applications.

Installation Notes

This disc is installed by machinists or precision grinding technicians operating lapping or flat-surface finishing equipment. Power down and de-energize the machine completely before mounting or removing the disc. Ensure the platen or support plate surface is clean and free of debris before pressing the PSA backing into place to achieve full adhesive contact. Follow the equipment manufacturer guidelines for disc speed and pressure settings appropriate to the material being worked.
