3M 7010325486 Microfinishing Film Roll 468L 100 Micron

Product Description

The 3M 7010325486 is a microfinishing film roll designed for precision surface finishing in industrial and metalworking applications. Built on a durable polyester film backing, this roll uses micron-graded silicon carbide abrasive to deliver consistent, repeatable surface finishes. The 100 micron grade is suited for controlled stock removal and surface refinement on ferrous and non-ferrous metals, composites, and other hard materials. At 17.5 inches wide, 150 feet long, and wound on a 3-inch core, this roll format is compatible with automated and semi-automated finishing equipment commonly found in production environments. Machinists, toolroom technicians, and production finishing operators are the primary installers and users of this product.

This microfinishing film roll is used in precision grinding, lapping, and finishing operations where tight surface finish tolerances are required. The 468L designation indicates a Type E unbacksized construction, meaning the film backing is not coated with a secondary sizing layer, which keeps the abrasive surface consistent throughout use. Typical applications include camshaft and crankshaft finishing, roller and bearing surface refinement, and general cylindrical or flat finishing work on production machinery. It is sold and used as a continuous roll for cut-to-length or machine-fed applications.

Key Features

• 100 micron silicon carbide abrasive for precise, consistent stock removal
• Polyester film backing provides dimensional stability under tension
• Type E unbacksized construction maintains abrasive consistency
• 17.5 inch width accommodates wide-format finishing equipment
• 150-foot roll length reduces changeover frequency in production settings
• 3-inch core fits standard roll-fed finishing machine mandrels

Compatibility

Designed for use with roll-fed microfinishing and superfinishing machines that accept 3-inch core rolls. Verify equipment roll width and core diameter specifications before installation.

Installation Notes

Installation is performed by qualified machine operators or maintenance technicians familiar with roll-fed abrasive finishing equipment. Power down and lock out the finishing machine before loading or replacing the abrasive roll. Follow the equipment manufacturer's instructions for tension settings and roll tracking. Avoid contact between the abrasive surface and oils or contaminants during handling, as this can affect finish consistency.
