On December 29, 2009, entrusted by Henan Provincial Department of Science and Technology, Zhengzhou Municipal Science and Technology Bureau organized relevant experts to research and develop two high-quality high-quality polycrystalline diamond wire drawing blanks for Henan Sifangda Superhard Materials Co., Ltd. And the "development and research of polycrystalline diamond composite sheets for super large diameter cutting tools" to identify scientific and technological achievements. The provincial and municipal leaders of the Department of Achievements of the Department of Science and Technology of Henan Province and the Director of the Achievements Division of the Zhengzhou Municipal Science and Technology Bureau attended the meeting. The appraisal committee consisted of seven experts from the industry.
The appraisal committee listened to the reports of the two projects, carefully reviewed the relevant appraisal materials and watched the products. After questioning and discussion, the appraisal opinions were formed. Its main evaluation is as follows:
The polycrystalline diamond wire drawing die blank project optimizes the raw material formulation and purification process; adopts high-efficiency cobalt removal process, and independently develops non-metal multi-component ceramic binder to replace cobalt-containing binder; research and design unique polycrystalline diamond core Structure; through the formulation research of the system, high temperature and high pressure cavity assembly structure design and sintering process research, prepare polycrystalline diamond wire drawing blank with diamond particle size 1-50 microns, polycrystalline size diameter 2.5-30 mm, thickness 1.0-20 mm Series products. It has been proved by users that the product has good wear resistance, high thermal stability, high processing efficiency and processing precision, long service life, and the main performance indicators have reached the international advanced level, which can replace imported and have good application prospects.
Based on the research of self-designed raw material formula, high-temperature and high-pressure chamber assembly structure and unique charging mode, as well as high-temperature and high-pressure sintering process, the polycrystalline diamond composite sheet project successfully developed a cutting diameter of 46 mm. Polycrystalline diamond compact for tools. It has been proved by users that the product has good wear resistance, good impact resistance, high processing efficiency and processing precision, long service life, and the main performance indicators have reached the international advanced level, filling the domestic gap and replacing imported. Promote application value and broad market prospects.
Through the identification of the two projects, the product quality is stable and the system is perfect. All of them have formed various specifications and realized large-scale production, sales and bulk export to meet the needs of different customers.
Based on the domestic six-sided top press to produce polycrystalline diamond wire drawing blanks with intrinsic quality and international advanced level, and the use of polycrystalline diamond compacts for super large diameter cutting tools, this has broken the long-term monopoly pattern of a few developed countries, and It has changed the situation that it has not been widely popularized due to the high price of products. It has perfected product specifications, based on domestic equipment, developed products with independent property rights, promoted the progress of the machining industry, and developed superhard materials and products with Chinese characteristics. Production is of great significance.
