What Is a Vitrified Diamond Wheel?
A vitrified diamond wheel is a high-performance grinding tool where diamond abrasives are bonded using a glass-ceramic (vitrified) bond. This unique bond offers superior heat resistance, porosity for coolant penetration, and exceptional grinding efficiency—making it ideal for precision machining of hard materials.
Key Technical Properties
| Parameter | Specification |
|---|---|
| Bond Type | Glass-ceramic (vitrified) |
| Porosity | 15–30% (adjustable) |
| Diamond Concentration | 25–150% (C25–C150) |
| Thermal Stability | Up to 600°C (dry), 1200°C (with coolant) |
Why Choose a 6A2 Vitrified Diamond Cup Wheel?
