3M Microfinishing Film Roll 373L is a high-quality product designed for microfinishing applications. It features a 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 precise and efficient finishing. The polyester cloth backing of the 373L film roll is known for its superior strength compared to paper backings. This makes it ideal for use on microfinishing machines, even when used wet. The backing remains strong and durable, even when applied to oscillating parts. One of the key advantages of the 373L film roll is the uniform distribution of the abrasive mineral over the backing. This ensures consistent and reliable performance, resulting in a smooth and even finish when sanding. Microfinishing is a critical process that helps correct the geometry of parts and create fine finishes. It can remove damaged or amorphous layers, improving the surface finish and roundness of the part. When selecting the right microfinishing film, operators should consider their target tolerances and choose the appropriate grade. The Microfinishing Film Roll 373L is available in a range of grades, each represented by a different color. This color-coded system helps reduce the risk of error, making it easier for operators to select the correct grade for their specific application. For operators looking to improve the geometry of parts and achieve desired finishes, the 3M Microfinishing Film Roll 373L is an exceptional choice. Its high-quality construction, anti-slip properties, and uniform abrasive distribution make it a reliable and efficient tool for microfinishing applications.
