3M Microfinishing Film Roll 373L

3M Microfinishing Film Roll 373L is a high-quality product designed for precision finishing applications. It features a unique friction coating made with quartz mineral, which provides excellent anti-slip properties. This means that the abrasive won't slip from machines or workpieces, ensuring a smooth and efficient finishing process.

The polyester cloth backing of the 3M Microfinishing Film Roll 373L is known for its exceptional strength and durability. Unlike paper backings, the polyester cloth backing can withstand wet applications on microfinishing machines and remains strong even when applied to oscillating parts. This makes it a reliable choice for operators who require consistent performance.

One of the key advantages of the 3M Microfinishing Film Roll 373L is the uniform distribution of the abrasive mineral over the backing. This ensures that the abrasive is evenly applied during sanding, resulting in a consistent finish. Whether you are working on camshafts, crankshafts, or transmission parts, this film roll will help you achieve the desired results.

Microfinishing is an essential process for correcting the geometry of parts and creating fine finishes. It can remove damaged or amorphous layers, improving the surface finish and roundness of the part. When selecting the right microfinishing film, it is important to consider the target tolerances. The 3M Microfinishing Film Roll 373L Type 2 film is available in a range of colors, each reflective of a specific grade. This color-coded system helps reduce the risk of error and ensures that operators can easily identify the appropriate film for their application.

If you are looking to improve the geometry of parts and achieve the desired finishes, the 3M Microfinishing Film Roll 373L is an exceptional choice. Its anti-slip properties, strong polyester cloth backing, and uniform distribution of abrasive mineral make it a reliable and efficient solution for microfinishing applications.
