CBN / Diamond Double Disc Wheels
Structure & Bonds
- Abrasive
- CBN grains: Second hardest abrasive after diamond, excellent for hardened steels.
- Diamond: Hardest known substance, excellent for non-ferrous materials.
- Bond Types
- Vitrified or resin bond depending on finish and stiffness requirements.
Typical Sizes & Precision
- Diameter: ~300 mm to 1000 mm typical range, but can be customized.
- Thickness & Width: Varies based on application (flat/parallel surface grinding).
- Accuracy: Flatness $\le 2\text{ µm}$
- Parallelism $\le 2\text{ µm}$
- Surface roughness $Ra\ 0.02\text{--}0.2\text{ µm}$ achievable on good machines.
Typical Applications
- Engine parts, pistons, bearings, compressor rotors, VALVE PLATES
- Precision machine components
- Hardened steels and metal alloys
- Hydraulic & pneumatic parts requiring tight flatness & surface finish
