On July 13, 2016, Henan Sifangda Superhard Materials Co., Ltd. ("Company" and "Sifangda") newly obtained 6 utility model patent certificates issued by the State Intellectual Property Office. details as follows: 
2. The special-shaped PDC flat grinding special fixture has the characteristics of simple structure, low cost and easy to use. The positioning plate is used to locate the outer circle of the PDC, which solves the problem of batch flat grinding of the shaped PDC, improves the loading efficiency and reduces the processing difficulty. , improve the processing accuracy.
3. The radial temperature measuring device in the synthesis chamber of the six-face top press can effectively measure the temperature distribution in the high temperature and high pressure synthesis chamber, so that the technician can control the temperature in the synthesis chamber.
4. The grinding wheel real-time dresser fundamentally solves the problem of rounding of the grinding wheel in the process of processing diamond products, can ensure the roundness of the grinding wheel, improve the precision and smoothness of the machined workpiece, simple structure, convenient operation, convenient adjustment, suitable for the width of the grinding wheel. It is more extensive, and if the size of the dresser is changed, it can be applied to the grinding wheel of any size.
5. A multi-blade shaped polycrystalline diamond composite sheet has simple structure, high utilization rate and low cutting resistance. In the drilling and drilling process, such multi-blade shaped polycrystalline diamond composite sheets are used as wear-resistant cutting elements. The structure does not have a large area of ​​stress concentration and sharp cutting, which can greatly improve the drilling drilling efficiency and the stability of the drilling platform; in addition, it can reduce the phenomenon of chipping, delamination or cutting resistance of the polycrystalline diamond composite sheet. It also exhibits the effect of extending the life of the drill bit.
6. A stress-reducing impact-resistant polycrystalline diamond compact has a simple structure and low manufacturing cost. The core of the polycrystalline diamond layer is filled with a material having a similar thermal expansion coefficient to the diamond, and the polycrystalline diamond layer can be made after synthesis. The low internal residual stress reduces the crack phenomenon caused by internal stress, reduces the occurrence of internal defects in the polycrystalline diamond layer, and improves the product yield. At the same time, the core of the polycrystalline diamond layer has good impact toughness and impact strength. High, and thus can enhance the impact resistance of the polycrystalline diamond compact, and improve the performance and service life of the polycrystalline diamond compact in the field of drilling.
The above patents have been applied in the production of the company's products. The acquisition of patents will not have a major impact on the company's production and operation, but it will help protect the company's intellectual property rights, form a continuous innovation mechanism, and enhance the company's core competitiveness.
