3M 7000000362 Microfinishing Film Roll 5 Mil 30 Micron

Product Description

The 3M 7000000362 is a Type E microfinishing film roll rated at 5 mil gauge with a 30 micron abrasive grade, wound in a 4-inch width by 150-foot length on a 3-inch ASO keyed core. It belongs to the 3M 472L series and is engineered for precision surface finishing where consistent stock removal and fine surface finish are critical. The film backing provides dimensional stability and a uniform cut rate across the full width of the roll. It is used by machinists, tool grinders, and production finishing technicians who require repeatable results on tight-tolerance workpieces.

This microfinishing film is suited for applications in precision grinding, lapping, and superfinishing operations on metal components. The 30 micron grade targets intermediate to fine finishing stages, removing scratches left by coarser abrasives and preparing surfaces for final polish. The roll format and keyed core design allow it to be loaded into automated or semi-automated film finishing equipment without slippage, making it appropriate for high-volume production environments as well as manual lapping setups.

Compatibility

Designed for use with film finishing equipment that accepts a 3-inch ASO keyed core and accommodates a 4-inch wide abrasive film roll.

Installation Notes

Loading and replacement of microfinishing film should be performed by a qualified machinist or finishing technician familiar with the specific equipment in use. Power down and de-energize all machine spindles and feed mechanisms before changing the film roll. Verify that the keyed core seats fully and locks in the machine's core holder before resuming operation. Follow the equipment manufacturer's tension and tracking guidelines to prevent film edge damage or uneven wear.
