Series of Resin Bond Diamond

BRD series are polycrystalline-like diamond graine, mainly used in resin bond diamond grinding wheels. Harmony Industry Diamond (H.I.D.) boron doped technology largely improve BRD series bond strengh accordingly, elevate bond retention capabilities to crystal. Polycrystalline-like diamond graine is composed of sub-crystals with mosaic structure that provides the graine with irregular shape and rough surface. Polycrystalline-like diamond can keep consistency of self-sharpening and sharp cutting edges.

Characteristics

Strong cutting force: There are a large number of sharp cutting edges on the surface of particles, and the cutting force can reach 2-4 times that of single crystal diamond powder.
High polishing accuracy: The cutting edge of single crystal diamond powder is large and hard, which is prone to deep scratches. The cutting edge of polycrystal-like diamond powder is small and its hardness is low. The Ra value of workpiece surface after polishing decreases significantly.
Strong grip strength: rough surface of particles and stronger bonding with binder can significantly improve grip strength of abrasives in various diamond products and improve service life.
