3M 7000045227 Microfinishing Film Roll 372L 15 Micron

Product Description

The 3M 7000045227 is a precision microfinishing film roll designed for tight-tolerance surface finishing of cylindrical workpieces. Aluminum oxide abrasive is resin bonded to a 5 mil polyester film backing, producing a durable, dimensionally consistent cutting surface. The backing features a friction grip coating that resists slipping during high-speed finishing operations. At 15 micron grade, this roll delivers fine material removal with repeatable surface finish results. Measuring 0.703 inches wide by 225 feet long, the roll is wound on 1 inch plastic cores compatible with standard film finishing equipment. It is suited for machine shops, automotive rebuild facilities, and precision grinding operations.

This microfinishing film roll is used in precision cylindrical finishing applications where controlled stock removal and consistent surface finish are required. Typical applications include finishing automotive camshafts, crankshafts, and similar round components on dedicated superfinishing or abrasive film machines. The 15 micron aluminum oxide formulation is appropriate for intermediate to fine finishing stages where surface geometry and finish must be held to close tolerances. Both production and repair environments will find this roll a practical fit for volume work on shaft and journal surfaces.

Key Features

• Aluminum oxide abrasive resin bonded to a 5 mil polyester film backing for dimensional consistency
• Friction grip coating on the backing reduces slippage during cylindrical finishing operations
• 15 micron grade provides fine, controlled cut for precision surface finishing
• 0.703 inches x 225 ft roll format supports extended production runs with minimal changeovers
• 1 inch plastic cores fit standard film finishing and superfinishing machine mandrels

Compatibility

Designed for use on dedicated microfinishing and abrasive film machines that accept 1 inch core rolls 0.703 inches wide, commonly used for cylindrical surface finishing of automotive and industrial shaft components.

Installation Notes

Loading and threading of microfinishing film rolls should be performed by the machine operator according to the equipment manufacturer's guidelines. Power down and de-energize the finishing machine before changing rolls. Ensure the core seats fully on the machine mandrel and the film tracks without lateral drift before resuming production. Inspect the film path for debris or sharp edges that could nick or tear the backing.
