PRODUCT FAQ
-
What is the purpose of 3M's Microfinishing Film Roll 372L?
The 3M Microfinishing Film Roll 372L is designed for precise finishing and polishing applications, providing consistent results on various surfaces.
-
Can this product be used for wet sanding?
Yes, the Microfinishing Film Roll 372L can be used for both wet and dry sanding applications, making it versatile for different project needs.
-
Is the plastic core durable and reusable?
The plastic core of this film roll is sturdy and reusable, ensuring easy handling during use and storage for future projects.
-
How long is the film roll in terms of length?
The Microfinishing Film Roll 372L measures approximately 900 feet (274.25 meters) in length, providing you with ample material to tackle your finishing tasks effectively.
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 FinishFilm 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 GeometriesManufacturers 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 Applications3M 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.
