SND-M15 Micron Diamond: Premium Precision for Lapping, Polishing & PCD Manufacturing
Description
SND-M15 is crafted with blocky crystal grains that provide enhanced durability and uniformity in high-precision tasks. Featuring a tightly concentrated particle size distribution (0–0.125~40–60μm) and ultra-low impurities (total impurities ≤0.1%, nitrogen ≤0.05%, boron ≤0.02%), this premium diamond ensures exceptional surface quality and material removal rates. The hydrophilic properties improve dispersion in water-based slurries, enhancing performance in automated polishing systems. Ideal for industries such as aerospace, optical glass, and luxury gemstone polishing, SND-M15 sets the benchmark for micron diamond performance.
Technical Edge & Engineering
- Crystal & Impurity Mastery: The blocky crystal structure resists fracturing under high pressure, ensuring superior performance in tough lapping and polishing applications. Ultra-low impurity content prevents optical discoloration and ensures consistent electrical properties for PCD tools.
- Particle Size Distribution (PSD): With a tightly controlled PSD (variance ≤5%), SND-M15 ensures each grain contributes uniformly to material removal, reducing surface imperfections by 35% compared to mid-tier diamonds. This is critical for applications requiring mirror-like finishes.
- Thermal Stability & Wear Rate: SND-M15 withstands temperatures up to 850°C, making it ideal for metal and electroplated bonds used in high-heat tasks. Its ultra-low wear rate (0.3–0.5% mass loss per hour) ensures 2–3 times longer tool life compared to premium generic diamonds, cutting replacement costs and downtime.
Key Advantages
- Precision Beyond Compare: Achieves Ra ≤0.2μm surface finishes, essential for aerospace components (e.g., turbine blades), optical glass (e.g., camera lenses), and luxury gemstones. In optical glass polishing, it eliminates the need for secondary buffing, cutting processing time by 40%.
- Industry-Leading Durability: Lasts 2–3 times longer than SND-M10 in high-load applications like PCD tool lapping. For instance, a metal-bonded wheel with SND-M15 can polish 500+ PCD cutting inserts compared to just 200–250 with SND-M10, significantly reducing downtime for manufacturers.
- Optimized for High-End Bond Systems: Works seamlessly with premium metal bonds, advanced electroplating, and PCD paste/slurry formulations. Its hydrophilic properties ensure excellent grit dispersion in water-based slurries, critical for consistent performance in automated polishing systems.
