3M 7000000315 Diamond Lapping Film Disc 5 Inch

Product Description

The 3M 7000000315 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 polyester film backing, delivering a consistent and repeatable finish across each use. Available in multiple grades ranging from 0.10 to 30.0 micron, this disc suits applications requiring tight surface finish tolerances. At 5 inches in diameter, it is sized for use with standard lapping and polishing equipment. Machinists, optical technicians, and precision tooling professionals typically install and use this disc in controlled finishing operations.

This diamond lapping film disc is suited for finishing extremely hard materials including ceramics, carbide, glass, and hardened metals. It is used in applications where a flat, uniform surface finish and sharp edge retention are required. Common use cases include lapping optical components, precision tooling surfaces, and finishing hard substrate materials in both production and laboratory settings. The disc format makes it compatible with rotary lapping machines and flat-lap polishing equipment.

• Available in grades from 0.10 to 30.0 micron to match a range of surface finish requirements
• Fast cut rate supports increased throughput in production finishing operations
• Produces flatter surfaces and sharper edges compared to conventional abrasive films
• Uniform finish across the full disc surface reduces rework
• Available in disc, sheet, and roll formats to fit different equipment configurations

Compatibility

Designed for use with standard rotary lapping and flat-lap polishing equipment that accepts 5-inch diameter abrasive discs. Suitable for finishing ceramics, carbide, glass, hardened metals, and other extremely hard materials.

Installation Notes

This disc is typically installed and used by machinists, optical technicians, or precision tooling professionals. Ensure the lapping plate or backing surface is clean and free of debris before mounting the disc to avoid uneven wear or scratching. Follow equipment manufacturer guidelines for disc attachment and rotational speed. Inspect the disc before each use and replace if abrasive loading or backing damage is observed.
