Big size synthetic diamond (BSSD) means the high quality grade Diamond Grits which the diameter is from 0.8mm to 4.2mm. Compared with traditional synthetic diamond, BSSD has the characteristics of: Bigger grits diameter, higher quality grade, higher TI/TTI data, more transparent, better crystal shape, more pure color.
Big size synthetic diamond can be divided into six quality grades:
SMD691: Perfect crystal color, regular shape, good transparency, high strength and great thermal stability. Suitable for making cutting tools. Also can be used as jewelry and replace natural diamond.
SMD690: Consistent crystal color, regular shape, good transparency, high strength and high thermal stability. Suitable for making tools for sawing all kinds of hard stone &concrete, for geological drills. It also can be used as jewelry.
SMD680: Complete crystal shape, perfect cubic octahedron, good diaphaneity, high impact strength and thermal stability. Suitable for high grade cutting, drilling and grinding tools.
SMD660: Complete crystal shape with full surface, good diaphaneity and low impurity, high strength. Suitable for circular saws, frame-saw and geological broaches.
SMD640: Comparatively regular crystal shape, high mechanic strength, belonging to middle quality grade among them, containing more regular crystal. Suitable for grinding and free-cutting tools, grinding wheels which work with medium load .
SMD620: Comparatively regular crystal shape, sharp edges, low strength, belong to low quality grade among them. Suitable for grinding tools and wheels that work with low load.
