3M 7000118194 Microfinishing Film Roll 100 Micron

Product Description

The 3M 7000118194 is a microfinishing film roll designed for precision surface finishing applications requiring consistent, repeatable results. Built on a durable polyester film backing, this roll uses micron-graded silicon carbide abrasive to deliver controlled stock removal and fine surface finishes. At 100 microns, it is suited for intermediate to fine finishing stages where dimensional accuracy and surface quality matter. The roll measures 17.75 inches wide by 150 feet long with a 3-inch core, making it compatible with standard roll-feed finishing equipment. It is used by machinists, tool and die professionals, and industrial finishing technicians working on tight-tolerance components.

This microfinishing film roll is used in precision grinding and finishing operations across metalworking, aerospace component prep, and industrial manufacturing environments. The Type E unbacksized construction and film base provide dimensional stability under tension, which is critical for consistent surface contact in automated or semi-automated roll-feed machines. It is appropriate for both flat and cylindrical workpiece finishing where grit uniformity and film integrity across the full roll length are required.

Key Features

• 100-micron silicon carbide abrasive for controlled, consistent material removal
• Polyester film backing provides dimensional stability and durability under tension
• 17.75-inch width accommodates wide-format roll-feed finishing equipment
• 150-foot roll length reduces changeover frequency in production environments
• 3-inch core fits standard roll-feed and lapping machine arbors
• Micron-graded construction ensures uniform finish across the entire roll

Compatibility

Designed for use in roll-feed microfinishing and lapping machines that accept 3-inch core rolls up to 17.75 inches in width.

Installation Notes

Installation of this roll is performed by machining or finishing technicians familiar with roll-feed abrasive equipment. Ensure the machine is fully de-energized and all rotating components have stopped before loading or replacing the roll. Thread the film through the machine according to the equipment manufacturer's feed path specifications, maintaining proper tension to avoid tracking issues. Inspect the roll for edge damage before use, as film tears can cause uneven finishing or equipment jams.
