The 3M Microfinishing Film Roll 372L features micron-graded premium aluminum oxide bonded to a 5 mil polyester film backing to deliver uniform results and meet stringent surface requirements. A friction grip coating provides slip resistance for microfinishing machines where film slippage is an issue, and close tolerance work on cylindrical surfaces, such as automotive camshafts and crankshafts.
- Micron-graded aluminum oxide abrasive cuts fast and provides a consistent, fine finish
- Durable polyester film backing provides flexibility for consistent finishing on contoured surfaces
- Polyester film backing can be run wet
- Available in a range of grades to help operators achieve goal tolerances
- Color-coded by grade for error proofing

Can you tell me more about the features included in this product like SP, ASO, ERMB, and Splice Tape?
Certainly! The SP feature stands for Stikit Pressure-sensitive adhesive backing that makes it easy to attach to various surfaces. ASO means Anti-static treatment to prevent dust build-up during use. ERMB refers to Enhanced Resin Bonding Technology for improved durability and consistent performance. The Splice Tape ensures smooth splicing when transitioning between rolls.

In order to achieve an extremely consistent scratch for microfinishing, 3M uses micron-graded mineral, measured at a very tight size tolerances for 3M Microfinishing Film Roll 372L. The resin bond ensures reliable, consistent performance. With a durable film backing, the abrasive helps achieve tight geometry and finish tolerances.
This microfinishing roll comes in a broad range of micron grades to achieve reproducible surface characteristics and geometric values that adhere to specification. In some applications, numerous grades are run simultaneously to achieve finishes that differ across the surface of a single complex part. To reduce risk of operator error, 3M designed Type 2 film in a range of colors reflective of each grade. The color coding is a useful visual cue, as is sorting width by core size and side and end of roll printing and marking.
Film Backing Provides Uniformly Flat Vehicle for Finer FinishFilm backings provide a superior, uniformly flat surface to hold abrasive particles - abrasive grains don't compress or become pressed into the backing. Highly conformable and tear-resistant, the polyester film backing flexes to help achieve a consistent finish over contours and is stronger than comparable paper products, making it ideal for high-production environments.
For Flawless GeometriesManufacturers of critical automotive components have little room for error in producing parts to specification. Power generation, life, noise, vibration and friction, fuel efficiency and emissions are all tied to the finishes of crankshafts and camshafts that rotate on increasingly thinner films of oil.
Engine component surfaces and geometry can be improved by using microfinishing which removes variations in the surface, minimizes friction and manipulates metal behavior in other ways.
Recommended Applications3M Microfinishing Films are used in the production of industrial components such as custom flanges and fittings for the oil and gas industry, as well as superfinishing of automotive parts, like crankshafts, camshafts and transmission parts.
