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
-
Certainly! Feel free to ask any other questions that you have regarding the 3M™ Microfinishing Film Roll 372L.
What is the width and length of the 3M™ Microfinishing Film Roll 372L?
-
The roll measures at approximately 0.669 inches in width and approximately 902 feet in length (16.99mm x 275m).
Can you tell me about the core material of this film roll?
-
The core of this microfinishing film roll is made of plastic, providing durability during usage.
How many rolls come in a single case of this product?
-
Each case contains eight rolls of the 3M™ Microfinishing Film Roll 372L.
What does "ASO" and "ERMR" stand for on this product specification?
-
"ASO" stands for Anti-Slip Overlap, providing stability during application. "ERMR" stands for Equal Runout Medium Response, offering consistent performance across applications.
Is there a specific recommended use or application process for this film roll?
-
This microfinishing film roll is designed for precision finishing tasks such as sanding, detailing, blending, or polishing various surfaces with ease.
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 like crankshafts, camshafts, and transmission parts.
A Portfolio of Abrasive Systems SolutionsFrom specialty abrasives designed for highly specific purposes to versatile sheets that can handle a variety of tasks, 3M offers a broad portfolio of abrasives. These abrasives are designed to shape, finish, and polish with ease and precision, drawing from a wealth of original technologies and breakthrough inventions.
