Product Description
Advantages of 3M™ Microfinishing Film Roll 372L
- 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
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 micro-finishing machines where film slippage is an issue, and close tolerance work on cylindrical surfaces, such as automotive camshafts and crankshafts.
Predictable, Consistent, Repeatable Performance
In order to achieve an extremely consistent scratch for micro-finishing, micron-graded mineral is used, measured at a very tight size tolerances for 3M™ Microfinishing Film Roll 372L. The resin bond ensures reliable, consistent performance. With a durable film backing, the abrasive helps achieve tight geometry and finish tolerances.
Film Backing Provides Uniformly Flat Vehicle for Finer Finish
Film backings provide a superior, uniformly flat surface to hold abrasive particles – abrasive grains don’t compress or become pressed into the backing. Highly conformable and tear-resistant, the polyester film backing flexes to help achieve a consistent finish over contours and is stronger than comparable paper products, making it ideal for high-production environments.
Recommended Applications for 3M™ Microfinishing Film Roll 372L
- custom flanges
- fittings
- automotive parts
- crankshafts
- camshafts
- transmission parts
