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 and long-lasting durability.

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 and improved surface quality. Whether you are working on camshafts, crankshafts, or transmission parts, this microfinishing film roll is designed to deliver exceptional results.

Microfinishing is an important application for many operators as it allows for the correction of part geometry and the creation of fine finishes. By removing damaged or amorphous layers, microfinishing can greatly improve the surface finish and roundness of the part. When selecting the right microfinishing film, it is important to consider the target tolerances and the specific requirements of the application.

The 3M Microfinishing Film Roll 373L is available in a variety of grades, each represented by a different color. This color-coded system helps reduce the risk of error and ensures that operators can easily select the appropriate grade for their specific needs. Whether you are aiming for a high-precision finish or need to remove imperfections, the 3M Microfinishing Film Roll 373L is an exceptional choice that can help you achieve your desired results.
