GCDMZ – Reshaped Micron Diamond Powder

20+ Years Experience Consistent Batch Quality Customized Solutions

Product Overview

GCDMZ is a reshaped monocrystalline micron diamond powder developed for precision lapping and polishing applications requiring controlled particle morphology, uniform abrasive contact and stable surface quality. Through additional shaping and classification, its particles exhibit reduced angularity and more consistent geometry than conventional crushed micron diamond, supporting controlled material removal and improved surface consistency on optical glass, sapphire, advanced ceramics and other hard materials.

Features

Reshaped Particle Morphology: Reduced angularity provides more controlled abrasive contact during lapping and polishing.
Improved Shape Consistency: Supports more uniform material removal and stable processing behavior.
Controlled Cutting Action: Helps reduce variation in abrasive penetration and supports consistent surface quality.
Controlled Particle Size Distribution: Supports repeatable lapping and polishing results across precision applications.

Customized Grades:
For precision and high-surface-quality applications, GCDMZ can be supplied with more rounded or near-spherical morphology, tighter PSD and oversize control, and enhanced purity according to specific process requirements.
