What Are Electroplated CBN Gear Grinding Wheels?
An electroplated CBN profile grinding wheel consists of a single layer of CBN abrasive grains bonded to a steel or aluminum core using an electroplating (nickel-bond) process. This creates an ultra-durable, high-precision grinding surface ideal for:
- Gear profile grinding (involute, cycloidal, and custom shapes)
- Hardened steel grinding (45-65 HRC)
- High-speed machining (80-150 m/s)
Key Features:
- Single-layer CBN wheel – No dressing required, maintaining consistent form accuracy.
- Non-dressable CBN wheel – Eliminates downtime for truing.
- Precision CBN grinding wheel – Achieves IT4-IT6 tolerances.
- CBN wheel for hardened steel – Ideal for Heat-Treated Gear, bearings, and tool steels.
