3M 7010325509 Diamond Lapping Film Disc 10 Inch

Product Description

The 3M 7010325509 is a diamond lapping film disc designed for precision surface finishing on extremely hard materials. The disc features precisely graded diamond particles coated onto a durable polyester film backing, delivering a consistent and repeatable finish with each pass. Available in grades ranging from 0.10 to 30.0 micron, this disc suits a wide range of finishing requirements where tight surface tolerances are critical. At 10 inches in diameter, it fits standard lapping and polishing equipment used in precision machining, optics, and fiber optic connector finishing applications. The lightweight construction at 0.06 pounds supports high-throughput workflows without adding unnecessary load to automated or manual finishing setups.

This diamond lapping film disc is used in applications requiring flat, burr-free surfaces and sharp edges on hard substrates including ceramics, carbide, glass, and optical components. It is commonly used by precision machinists, optical technicians, and fiber optic technicians in both production and maintenance environments. The disc format is suitable for use on rotary lapping machines and flat-lap systems. The polyester film backing provides dimensional stability during use, helping maintain consistent contact across the full disc surface.

Key Features

• Precisely graded diamond abrasive particles for consistent, repeatable finish results
• Polyester film backing provides dimensional stability and flat surface contact
• Available in multiple micron grades from 0.10 to 30.0 micron for fine to medium material removal
• Fast cut rate supports increased throughput on hard materials
• Produces flatter surfaces and sharper edges compared to conventional abrasive films
• Available in disc, sheet, and roll formats for versatile equipment compatibility

Compatibility

Designed for use on standard rotary lapping and flat-lap equipment accepting 10-inch diameter disc abrasives. Suited for finishing extremely hard materials including ceramics, carbide, glass, and optical substrates.

Installation Notes

Installation and use should be performed by qualified precision machining or optical finishing technicians familiar with lapping equipment operation. Ensure the lapping machine is powered down and fully stopped before mounting or removing the disc. Secure the disc evenly on the platen to ensure full surface contact and prevent uneven wear. Follow the equipment manufacturer guidelines for speed settings appropriate to the selected micron grade and material being finished.
