3M Microfinishing Film 372L Rolls
An aluminum oxide micron roll resin bonded to a 5 mil polyester film backing. The backing has a friction grip coating for slip resistance. Precision finishing of cylindrical surfaces such as automotive camshafts & crankshafts.
Key Characteristics
- Micron-graded premium aluminum oxide for uniform abrasive action.
- Durable 5 mil polyester film backing for consistent finishing.
- Friction grip coating to prevent slippage in microfinishing machines.
- Resin bond for reliable, consistent performance.
- Available in a broad range of micron grades for specific surface finishes.
- Color-coded by grade for easy identification and reduced operator error.
Use For
- Microfinishing in automotive applications, particularly camshafts and crankshafts.
- Applications requiring highly uniform scratch patterns.
- Processes where tight geometry and finish tolerances are essential.
- Industries needing a reproducible surface characteristic and geometric values.
- Complex parts requiring multi-grade finishing for varied surface characteristics.
