3M industrial and occupational products are intended, labeled, and packaged for sale to trained industrial and occupational customers for workplace use. Unless specifically stated otherwise on the applicable product packaging or literature, these products are not intended, labeled, or packaged for sale to or use by consumers (e.g., for home, personal, primary or secondary school, recreational/sporting, or other uses not described in the applicable product packaging or literature), and must be selected and used in compliance with applicable health and safety regulations and standards (e.g., U.S. OSHA, ANSI), as well as all product literature, user instructions, warnings, and other limitations, and the user must take any action required under any recall, field action, or other product use notice. Misuse of 3M industrial and occupational products may result in injury, sickness, death, or property damage. For help with product selection and use, consult your on-site safety professional, industrial hygienist, or other subject matter expert.

Predictable, Consistent, Repeatable Performance

In order to achieve an extremely consistent scratch for microfinishing, 3M utilizes micron-graded mineral that is measured at very tight size tolerances for the 3M Microfinishing Film Roll 372L. The resin bond ensures reliable and consistent performance. With a durable film backing, this abrasive helps achieve tight geometry and finish tolerances.

This microfinishing roll is available in a wide range of micron grades, allowing for reproducible surface characteristics and geometric values that adhere to specifications. In certain applications, multiple grades are used simultaneously to achieve different finishes across the surface of a single complex part. To minimize the risk of operator error, 3M has designed Type 2 film in various colors that reflect each grade. The color coding serves as a useful visual cue, along with 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 and uniformly flat surface to hold abrasive particles, preventing them from compressing or becoming pressed into the backing. The polyester film backing is highly conformable and tear-resistant, allowing it to flex and achieve a consistent finish over contours. It is also stronger than comparable paper products, making it ideal for high-production environments.

For Flawless Geometries

Manufacturers of critical automotive components cannot afford any errors when producing parts to specification. The finishes of crankshafts and camshafts, which rotate on increasingly thinner films of oil, have a significant impact on power generation, life, noise, vibration, friction, fuel efficiency, and emissions. Microfinishing can improve engine component surfaces and geometry by removing variations in the surface, minimizing friction, and manipulating metal behavior in other ways.

Recommended Applications

3M Microfinishing Films are commonly used in the production of industrial components such as custom flanges and fittings for the oil and gas industry. They are also used for superfinishing automotive parts, including crankshafts, camshafts, and transmission parts.
