- Sharp Multi-Angular Blocky Crystals: Creates strong mechanical interlocking with the electroplated metal layer to prevent grain pull-out.
- Optimised Crystal Geometry: Irregular polyhedral shape with sharp edges enhances cutting aggressiveness and contour precision.
- High Crystal Strength: Low internal defects provide sufficient toughness to withstand impact loads during grinding and cutting.
- Excellent Self-Sharpening Performance: Micro-fracturing of cutting edges maintains continuous sharpness during operation.
- High Surface Cleanliness and Activity: Chemically treated surface improves metal encapsulation and bonding reliability.
- Strict Grit Size Control: Concentrated particle size distribution ensures uniform cutting force and stable tool performance.
GCD30 – Electroplated Crushed Diamond Powder
20+ Years Experience
Ultra-Precision Quality
Customized Solutions
GCD30 is an electroplating-grade crushed diamond powder specifically developed for nickel and nickel-cobalt electroplated tools requiring maximum grain retention and sharp cutting performance. Manufactured from high-quality synthetic single crystal diamond, this grade is optimized to achieve strong mechanical bonding with the metal plating layer while maintaining high cutting efficiency and profile accuracy.
