Product Description

Key Features

1. CBN Abrasive Superiority

   • Second only to diamond in hardness, CBN grains provide exceptional abrasion resistance and durability.

   • Ideal for grinding ferrous materials (e.g., hardened steel, cast iron, and high-temperature alloys) without excessive wear.

2. Exceptional Precision & Surface Finish

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

   • Consistent grain distribution ensures uniform material removal and minimal runout.

3. High Thermal Resistance

   • Withstands high grinding temperatures without degrading, reducing the risk of workpiece thermal damage.

   • Maintains wheel integrity and cutting performance even under intense operational conditions.

4. Customizable Design

   • Available in various shapes (e.g., straight, tapered, flared), grit sizes (e.g., 100-800+), and bonds (vitrified, electroplated, resinoid).

   • Tailored for specific applications, including bore grinding, ID grinding, and contour grinding.

5. Long Service Life

   • Outperforms conventional aluminum oxide wheels by 10x or more in lifespan.

   • Reduced frequency of wheel changes increases productivity and lowers cost per part.
