In the report section of the conference, Professor Wang Qinsheng, Honorary Chairman of the Diamond and Products Branch of the Chinese Society of Mechanical Engineering, presented a report titled "Bottlenecks in the Development of China's Diamond Industry - Problems and Countermeasures in Industrial Development". Professor Wang pointed out that China's superhard industry occupies an important position in the world, with 90% of the global production of rough diamonds cultivated by high-temperature and high-pressure methods, and 80% of the national production capacity in Henan. However, in the industry chain of cultivating diamonds from rough stones to rough diamonds and then to finished diamonds, the processing of rough diamonds heavily relies on India, with 90% of rough diamond processing completed in India. This situation urgently needs to be changed. Only by solving the problems of bare diamond cutting, grinding, and polishing processes, and getting rid of dependence on India, can we truly open up the market space for cultivating the diamond industry in China.

 

Professor Wang Chengyong, Vice President of Guangdong University of Technology, has also drawn attention to his report on "Full Laser Processing of Diamond Parts and Medical Applications of Diamond".
