3M 7000000256 Diamond Lapping Film Roll 60.0 Micron

Product Description

The 3M 7000000256 is a diamond lapping film supplied in roll form, designed for precision material removal and surface finishing in demanding industrial and trade applications. Built on a reinforced resin system for added toughness and extended service life, this film delivers consistent cutting action across its 60.0 micron grade. The roll measures 8 inches wide by 50 feet long on a 3-inch core, making it compatible with standard roll-fed lapping and polishing equipment. It is used primarily by machinists, toolroom technicians, and precision finishing specialists who require repeatable surface quality on tight-tolerance workpieces.

This diamond lapping film is suited for superfinishing, roll polishing, and flat lapping operations on hard materials including carbide, ceramics, and hardened steel. The 60.0 micron grade positions it for stock removal and initial surface conditioning stages before progressing to finer grades. The roll format supports continuous-feed machine setups in production environments as well as controlled bench-top lapping fixtures used in toolroom and maintenance contexts.

Key Features

• 60.0 micron diamond abrasive grade for consistent stock removal and surface conditioning
• Reinforced resin bond system provides added toughness and longer working life compared to standard lapping films
• Roll format: 8 inches wide by 50 feet long on a 3-inch core for continuous-feed machine compatibility
• Suited for superfinishing, roll polishing, and flat lapping applications
• Diamond abrasive cuts effectively on hard substrates including carbide, ceramics, and hardened steel

Compatibility

Designed for use with standard roll-fed lapping, polishing, and flat lapping equipment that accepts an 8-inch wide, 3-inch core roll format.

Installation Notes

Installation and setup should be performed by qualified machinists or precision finishing technicians familiar with roll-fed lapping equipment. Ensure the machine is fully powered down and de-energized before loading or changing the film roll. Thread the film according to the equipment manufacturer's feed path specifications to prevent edge damage or misalignment. Secure all guards and covers before resuming operation.
