The formation of polycrystalline diamond powder

Polycrystalline diamond material is a strong shock waves, synthetic cubic diamond crystals. It is different from the production of nano-detonation single crystal diamond. This micro grain  abrasive grinding unsaturated bond connected to form nano, submicron, micron "aggregate polycrystalline particles," they are isotropic, no cleavage plane. Not only has the unmatched hardness and strength, but also has high toughness, and thus overcome the static pressure (mechanical top pressure) synthesized single crystal diamond material is easily brittle cleavage plane and detonation  cubic boron nitride soft reunion and other shortcomings. Therefore, each one has a lot of polycrystalline diamond grinding surface, the grinding process can adjust the grinding parameters for grinding, fine grinding and ultra-fine grinding. And in the grinding and polishing process will automatically flaking showing timely new cutting edge micro. This "self-sharpening" ensure the machining of high precision, high efficiency and will not damage the shallow surface layer.
