GCDM30 – Electroplating-Grade Micron Diamond Powder

20+ Years Experience Consistent Batch Quality Customized Solutions

Product Overview

GCDM30 is a high-quality monocrystalline micron diamond powder specifically developed for electroplated diamond tools and other high-load grinding systems. Produced from high-toughness HPHT synthetic diamond through controlled crushing and milling, this grade features blocky crystal morphology, narrow particle size distribution, and ultra-low impurity content, delivering strong grain retention, stable cutting performance, and excellent surface finish in precision grinding and polishing applications.

Features

High Particle Integrity:
Helps maintain stable abrasive geometry during precision processing.
Controlled Blocky Morphology:
Supports uniform abrasive contact and stable grit exposure in electroplated tools.
Concentrated Particle Size Distribution:
Promotes consistent cutting depth and repeatable surface quality.
Stable Wear Behavior:
Supports reliable performance during extended lapping, polishing and precision tool use.
