From left: Dr. Wang Yuchang Gorgeous professor Professor Wang Guangzu, Dr. Wang Yuchang Liu Jinchang general manager said: diamond cubic press is the size of the current has become a trend, but should not be quick success, because the problem is not just large-scale press equipment manufacturing technology, pressure The large-scale machine needs related supporting technologies and equipment to meet the requirements at the same time. In this regard, the current situation is not satisfactory. 
Dr. Wang Yuchang First, the domestic related cemented carbide top hammer manufacturing technology can not keep up with the rapid pace of diamond presses. With the large-scale press, it is bound to have higher requirements for the top hammer. However, the quality of the top hammer, especially the domestic top hammer, is still not up to the requirements of the top hammer of our preset press. Second, the quality of the pyrophyllite has not been found to adapt to the fast pace of the large-scale press. The large size of the press also means that the size of the pyrophyllite block is increased, and the sealing and quality uniformity and consistency of the pyrophyllite have higher requirements. Need better quality pyrophyllite, and the current situation is that there is a certain hidden worry in the existing domestic pyrophyllite. Beijing restricts the exploitation of pyrophyllite in Mentougou, while the pyrophyllite grades found in other places are still far from the Mentougou, which is difficult to meet the synthetic high-grade diamond. Requirements. Wang Yuchang Said: due to the short board of other supporting equipment and materials, if the development of tonnage and excessive cylinder diameter will directly lead to an increase in production costs, and we develop the purpose of large-scale presses to increase production and reduce costs, so pressure The large-scale operation of the machine should be carried out steadily, lay a good foundation, and do research on related supporting technologies and equipment. 
The process of large-scale presses should be stable--China Superhard Materials Network visits Henan Huanghe Cyclone Co., Ltd.
On October 20th, Liu Jinchang, general manager of China Superhard Materials Network, Shi Chao, deputy general manager, Professor Wang Guangzu, expert of diamond industry, and professor of Henan University of Technology visited Henan Huanghe Cyclone Co., Ltd., and detailed with Dr. Wang Yuchang of R&D Center Have a conversation.
