Research on Shaped End Face Diamond Composite Sheet Technology . Drilling the external tooth type diamond composite chip drill tooth is to change the diamond chip face of the diamond tooth from the plane to the tooth surface, the tooth surface can be wavy, sawtooth or trapezoidal. When welding diamond composite drill bits, the profiled groove on the diamond face should be directed to the rock face. During the rock drilling work, the working part (edge) with grooved teeth gradually forms a row of “teeth”, which cuts the rock The ability and effect far outperforms the flat toothless diamond composite drill, and this effect can basically be maintained until the entire drill tooth fails. The use of this new type of drill to make a drill bit can significantly improve the rock breaking efficiency of the diamond composite drill bit, especially for weak rock formations, and solves the technical difficulties of the diamond compact slide.
6) Study with little or no added cemented-phase polycrystalline diamond technology. It is a long-term goal for experts and scholars in the field of ultra-high-pressure synthesis of polycrystalline diamond (PCD) to sintered diamonds together with little or no added cementitious phase. Since the successful development of transparent polycrystalline cubic boron nitride, it has been expected that pure, transparent PCD with a certain thickness can be born. Because pure PCD will not only make a leap in the performance of the tool material, it will also usher in a wide range of application space on functional materials.
