Vitrified Bond CBN Grinding Wheels for Internal Grinding

Product Description

Key Features

1. Exceptional Hardness & Wear Resistance

   • CBN abrasives (second hardest material after diamond) provide outstanding durability and longevity, outperforming conventional wheels by 10-20x in lifespan.

   • Minimal wheel wear ensures consistent performance and reduces downtime for wheel changes.

2. Vitrified Bond Advantages

   • High thermal stability prevents wheel deformation at elevated temperatures, maintaining precision under aggressive grinding conditions.

   • Excellent dressability allows for easy profiling and sharpening of the wheel, ensuring optimal grinding geometry.

   • Porous structure facilitates efficient chip evacuation and coolant penetration, reducing heat buildup.

3. Superior Surface Finish & Precision

   • Achieves fine surface finishes up to Ra ≤ 0.1 µm and tolerances within ±0.001 mm.

   • Ideal for applications requiring minimal metallurgical damage, such as grinding hardened tool steels and aerospace components.

4. High Material Removal Rates (MRR)

   • Aggressive yet controlled cutting action reduces cycle times by up to 30% compared to resin-bond alternatives.

   • Suitable for both roughing and finishing operations.

5. Customization Flexibility

   • Available in a wide range of grit sizes (100-2000), shapes (straight, tapered, flared), and dimensions to fit specific internal grinding needs.

   • OEM/ODM support for unique applications.
