Product Information Of Electroplated CBN wheel for grinding and sharpening
Electroplated Cubic Boron Nitride (CBN) grinding and sharpening wheels are high-performance abrasive tools designed for precision grinding of very hard materials.
A **single layer** of high-quality CBN abrasive grains is **electrochemically bonded** (plated) onto a precision-made metal core (usually steel or aluminum).
* This creates a wheel with the abrasive grains held firmly at their bases, leaving their sharp cutting edges fully exposed.

Advantages:
1. **Extreme Hardness & Wear Resistance:** CBN is the second hardest known material (after diamond), making these wheels exceptionally durable and long-lasting, especially when grinding ferrous materials (where diamond would rapidly degrade).
2. **High Abrasive Exposure:** The single-layer, electroplated bond exposes a very high percentage of each grain. This results in:
* **Free Cutting Action:** Reduced cutting forces and less tendency to "glaze."
* **Excellent Coolant Access:** Efficient heat removal at the cutting zone.
* **High Material Removal Rates (MRR):** Especially for light to moderate stock removal.
* **Superior Surface Finish:** Achievable due to sharp, consistent cutting.
* **Minimal Heat Generation:** Critical for preventing workpiece burn, temper loss, or metallurgical damage.
3. **Long Wheel Life:** Due to CBN's hardness and wear resistance, these wheels last significantly longer than conventional abrasive wheels (like AlOx or SiC) or even resin-bonded CBN wheels on suitable applications.
4. **Form Holding:** Ideal for grinding complex profiles and maintaining sharp edges (like in sharpening) because the grains don't fracture or wear significantly during grinding. The wheel profile remains stable until the grains are completely worn or pulled out.
5. **No Dressing Required:** Electroplated wheels come ready to use and **cannot be dressed or trued** in the conventional sense. This eliminates downtime for dressing but means the wheel must be discarded once worn.
6. **High Grinding Speeds:** Can operate at high peripheral speeds (often 80-160 m/s), increasing productivity and often improving surface finish.
7. **Versatility in Forms:** Can be manufactured in a wide variety of complex shapes, profiles, and small diameters (e.g., points, cones, cylinders, custom forms) due to the plating process.
