Product Number 372L

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

PRODUCT FAQ

  1. What is the width and thickness of the 3M™ Microfinishing Film Roll 372L, 0.906 in x 900 in x 1.5 in, 20 Mic,

    5MIL, T2, ASO?

  2. The width of the film roll is approximately 0.906 inches (2.30 cm) and it has a length of around 900 inches (22.86 meters). The thickness measures up to be about 1.5 inches thick (3.81cm).

    How many rolls are included per case for this product?

  3. There are six rolls included per case of the microfinishing film roll.

    Does each roll have an identification marking on it?

  4. Yes! Each end roll mark on these red-colored microfinishing films helps identify what type they are which makes finding your preferred grit even easier.

    Is this product suitable for auto-body work operations?

  5. Absolutely! With versatile applications such as clear coat sanding defects removal or surface preparation before painting - you can definitely trust us when we say that our Microfinishig Film Roll will deliver excellence no matter how tough your job site

Predictable, Consistent, Repeatable Performance

3M™ Microfinishing Film Roll 372L achieves an extremely consistent scratch for microfinishing by using micron-graded mineral, measured at tight size tolerances. The resin bond ensures reliable, consistent performance. The abrasive has a durable film backing that 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.

3M designed Type 2 film in a range of colors to reduce the risk of operator error. The color coding is a useful visual cue, as is sorting width by core size and side and end of roll printing and marking. In some applications, numerous grades are run simultaneously to achieve finishes that differ across the surface of a single complex part.

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. The polyester film backing is highly conformable and tear-resistant, flexing to help achieve a consistent finish over contours. It 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. Microfinishing removes variations in the surface, minimizes friction, and manipulates metal behavior in other ways. Engine component surfaces and geometry can be improved by using microfinishing, which is essential for finishes of crankshafts and camshafts that rotate on increasingly thinner films of oil.

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.
