Cleavage of single crystal diamond directional fragmentation and performance disadvantages such as

As polycrystalline diamond material is composed of many fine grains of diamond free orientation formed to overcome cleavage of the single crystal diamond directional fragmentation and  synthetic diamond shortcomings. In addition to lower hardness than outside the single crystal diamond, polycrystalline diamond material has a hardness uniform, isotropic and good toughness, etc., can be made into various shapes can also be  Abrasive grinding wheel to the specific ingredients and manufacturing processes, develop the application of diamond areas, especially in geology, petroleum, mining drills and cutting tools, wire drawing dies and other fields has polycrystalline diamond . Since the inception of polycrystalline diamond material, its variety, quantity, and performance has greatly developed and improved. As superhard polycrystalline diamond material, wear, the molding process is very difficult. Experimental studies have shown, using a slotted diamond wheel tool grinder in general the higher the efficiency of the grinding polycrystalline diamond material, its processing mechanism article will conduct in-depth research.
