PRODUCT FAQ

  1. bsolutely! Here are 5 common questions customers might ask about the 3M™ Microfinishing Film Roll

    What is the grit size of the Microfinishing Film Roll 372L?

  2. The grit size of this roll is 15 microns, which makes it ideal for achieving fine finishes on various surfaces.

    How long is the roll of Microfinishing film?

  3. The length of this particular roll is a generous 591 feet, providing you with plenty of material for your projects.

    What type of core does the film roll have?

  4. The film roll features a plastic core that helps maintain its shape and stability during use.

    What width does this specific film come in?

  5. This film has a width of approximately 2.087 inches (53mm), suitable for precise sanding and finishing tasks.

    What does ASO stand for in relation to this product?

  6. ASO stands for "Anti-Static Optimized," indicating that this film roll has been engineered to minimize static charge buildup during operation, promoting a cleaner work environment.

Predictable, Consistent, Repeatable Performance

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 Finish

Film 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 Geometries

Manufacturers 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 Applications

3M 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.
