CBN Wheel New Breakthrough: Ruizuan Launches Efficient Grinding Solution for High-Speed Steel Rolls

At Zhengzhou Ruizuan Diamond Tool Co.,Ltd., we are proud to announce a groundbreaking advancement in grinding technology: our newly developed resin-bonded CBN grinding wheel is set to revolutionize the machining of high-speed steel (HSS) rollers, delivering unmatched efficiency, precision, and longevity compared to conventional grinding wheel.

The Challenge: Traditional grinding wheel Limitations in HSS Roller Grinding
High-speed steel rollers are critical components in industries such as steel manufacturing, paper production, and heavy machinery, where they endure extreme wear and require ultra-precise surface finishes. However, traditional aluminum oxide or silicon carbide grinding wheel often struggle with:
• Short tool life, leading to frequent grinding wheel changes and downtime.
• Poor surface finish, requiring additional polishing steps.
• Thermal damage risk, affecting rollers metallurgical properties.

Our Solution: Next-Gen Resin CBN grinding wheel for HSS Rollers
Ruizuan’s resin CBN grinding wheel is engineered to overcome these challenges with three key innovations:
1. High-Performance CBN Abrasives
  • Cubic Boron Nitride (CBN) grains provide 5x longer lifespan vs. conventional abrasives.
  • Exceptional heat resistance (up to 1,400°C), minimizing thermal damage to rollers .
2. Modified Phenolic Resin Bond System
  • Enhanced elasticity and porosity for cooler cutting and reduced workpiece burns.
  • Self-sharpening design maintains consistent grinding performance without glazing.
3. Optimized Grain Structure
  • Uniform abrasive distribution ensures Ra ≤ 0.4 μm surface finish in a single pass.
  • Ideal for roughing to finishing operations, eliminating multi-step processes.

Proven Performance in Industrial Applications

Extensive field testing demonstrates:
✔ 40% longer operational life than competing products
✔ 30% faster material removal rates
✔ Elimination of workpiece annealing effects

Why This Matters Now
With global demand for high-precision rollers surging in renewable energy (wind turbine shafts) and EV battery foil production, our CBN grinding wheel enables manufacturers to:
✅ Reduce machining costs by minimizing grinding wheel replacements.
✅ Achieve mirror-like finishes without secondary operations.
✅ Extend rollers service life through damage-free grinding.
