Product Introduction
The 3M™ Vitrified Grinding Wheel 91VB is engineered to improve roughing and finishing performance in gear and crankshaft grinding. Featuring a proprietary blend of alumina and ceramic grains, including 3M™ Cubitron™ II precision-shaped grain and NA series abrasives, it delivers fast cutting, stability, and exceptional profile accuracy. With self-sharpening behavior and extended dressing intervals, the wheel increases productivity, reduces cycle time by over 20%, and maintains tight tolerances with high-quality surface finishes.
3M™ Vitrified Grinding Wheel 91VB Features:
- Advanced alumina and ceramic grain blend for high cutting efficiency
- Designed for crankshaft and gear grinding stages
- Low grinding temperatures minimize thermal damage
- Self-sharpening abrasive maintains sharp cut rate
- Profile accuracy ffα < 2µm and Rz < 2.5µm
- Higher feed rates reduce grinding time by over 20%
- Extended dressing intervals reduce downtime and cost
- High stability ideal for precision components
- Supports machine balancing performance
- Cubitron™ II + NA series blend for optimized removal rates
3M™ Vitrified Grinding Wheel 91VB Applications:
- Crankshaft grinding
- Gear grinding—roughing and finishing
- Precision part grinding
- Applications requiring minimal heat input
- High-tolerance and fine-finish component grinding
