Saint-Gobain Surface Conditioning's resin bond mesh diamond is a synthetic material with a friable crystal structure for use in vitrified and resin bond systems. The crystals are irregular, elongated and rough-edged, and are suitable for grinding tungsten carbide, ceramics and glasses.
The friability or breakdown of the diamond is a function of its polycrystalline structure and metallic inclusions within the grains. Grains are microfractured during grinding and new edges formed for efficient, free-cutting action.
Resin bond mesh diamond is typically 40µm and larger in particle size and is available in standard electroless nickel (Ni) coatings of 30% and 56% by weight, and a copper (Cu) coating of 50% by weight.
