Introduction
Surface finish isn’t just about aesthetics — it’s about functionality. From bearing performance to heat resistance, the finish of a part can directly influence product lifespan, energy efficiency, and user safety.
Why Surface Finish Matters
- Improved wear resistance
- Lower friction during operation
- Stronger bonding during coating or painting
- Enhanced fatigue strength
In industries like aerospace and automotive, a 1–2 micron variation in finish can make the difference between precision and failure.
Abrasives: The Unsung Hero of Surface Control
At CUMI, we’ve engineered abrasive tools that offer tight tolerance surface finishing while maintaining durability under pressure.
Popular products include:
- Precision vitrified wheels
- Resin bond diamond tools
- Surface finishing discs with uniform grain distribution
