3M 7010325376 Diamond Psa Disc 8 Inch Lapping

Product Description

The 3M 7010325376 is a diamond metal bond pressure-sensitive adhesive (PSA) abrasive disc designed for precision lapping, finishing, and polishing applications. Micron-graded diamond mineral is adhered to a brass plate, producing a disc that cuts sharply while still delivering fine surface finishes. At 8 inches in diameter, it attaches directly to a machine platen or support plate via its PSA backing for fast, secure mounting. This disc is well suited for applications where consistent material removal and surface quality are both critical requirements, and it is commonly used by toolroom machinists, optical fabricators, and precision grinding technicians.

This disc is designed for lapping and fine finishing operations on hard or demanding substrates. Its evenly spaced diamond mineral layout promotes uniform stock removal and helps eliminate workpiece imperfections at a controlled rate. Suitable substrates include ceramic, carbide, glass, and other hard materials that conventional abrasives struggle to process effectively. It is sold individually and sized for standard 8-inch lapping machines and rotary platens.

Key Features

• PSA backing allows quick, tool-free attachment to machine platens or support plates
• Micron-graded diamond mineral delivers sharp cutting action with fine finish capability
• Brass plate bond construction provides stable mineral retention during lapping cycles
• Evenly spaced abrasive pattern promotes consistent, controlled material removal
• Compatible with ceramic and other hard substrates that resist conventional abrasives
• Suitable for lapping, finishing, and polishing operations

Compatibility

Designed as an OEM-style replacement and general-use abrasive disc for 8-inch rotary lapping machines and platens that accept PSA-backed discs.

Installation Notes

Power down and lock out the lapping machine before mounting or removing the disc. Ensure the platen surface is clean and free of debris before pressing the PSA backing into place to achieve full adhesion and prevent disc slippage during operation. This product is typically installed by toolroom machinists or precision grinding technicians following equipment manufacturer guidelines for disc replacement.
