At 9:00 in the morning, the opening ceremony of the conference was held. Mao Yufeng, executive vice president of China Machine Tool & Tool Industry Association, Qiu Lihua, chairman of Superhard Materials Branch of China Machine Tool Industry Association, Zhu Zhuping, director of Sixth Grinding Wheel Factory, and Zhengzhou Abrasives Grinding Research Institute The old expert Lu Feixiong gave a speech at the opening ceremony, and then Secretary Zhao Bo announced the 20th China Superhard Materials Technology Development Forum and the “Celebration of the 50th Anniversary of the Birth of China's Cubic Boron Nitride”.
In order to commemorate the 50th anniversary of the birth of China's cubic boron nitride, in order to better guide enterprises to adjust the structure in the new situation, promote growth, and maintain the healthy and orderly development of the industry, this conference specially prepared three major themes: "China Cube" The development of boron nitride for 50 years, the research history and technology development trend of China's cubic boron nitride abrasive tools, and the history and current status and prospects of PCBN material tools in China.
Zhang Xiangfa, deputy general manager of Zhengzhou Zhongnan Jiete Superhard Materials Co., Ltd., gave a keynote report on "The Development of China's CBN for 50 Years"
"China's cubic boron nitride development for 50 years" report said: "China's cubic boron nitride since its birth in 1966, broke the foreign technology blockade, filled the national gap, perfected the members of the superhard material family; experienced half The century has gone through 50 years of glory, innovating a completely independent intellectual property right, the world's unique equipment and process technology, forming a complete industrial system of research and development, production and application; not only meets the national major equipment manufacturing and even all mechanical plus The high-end demand of industry has strongly supported and promoted the development of the manufacturing industry, and made outstanding contributions to the development of the world's manufacturing industry!
After 50 years of development, China's cubic boron nitride field has fully utilized and borrowed the development achievements of the diamond field, developed a full range of products, and achieved great achievements that have attracted worldwide attention. The output of single crystal accounts for about 70% of the world's total. The world's first, the quality of most single crystal varieties has reached the world's advanced level, we can say that we have won the single champion of the world cubic boron nitride single crystal production; cubic boron nitride products are efficient, high precision, energy saving, Green environmental protection products have great support for high-end equipment manufacturing. The advent of such products, like diamond products, not only solves the problem that new materials that are endlessly formed cannot be processed with traditional tools, but also increases the efficiency of traditional processing by hundreds of times, and reduces consumption and waste emissions hundreds of times. The quality of some cubic boron nitride products in China has also reached the world advanced level. They are the irreplaceable extreme materials and tools necessary for the development of a low-carbon economy. They have won unprecedented attention in the world and have immeasurable development prospects.
In China's cubic boron nitride from scratch, from small to large, from the weak to strong, the great journey, the wisdom of several generations of warriors, showing the heroes of several generations. I would like to express my deep respect and sincere gratitude to all those who have contributed to the development and development of the cubic boron nitride industry!
We must be soberly aware that there is still a gap between the individual varieties of cubic boron nitride single crystals and the level of developed countries. There is a big gap between polycrystalline and composite materials, and most products have a larger gap. The future development space is huge, full of challenges and full of hope!
We must seize the world's pursuit of high-precision, high-efficiency, environmentally-friendly development opportunities, carry forward the spirit of innovation, adhere to the glorious tradition of hard work, unite and work hard, and strive to promote China's cubic boron nitride business as soon as possible to catch up with the world's advanced Level! Make greater contributions to the development of human civilization!"

Liu Mingyao, deputy general manager of SINOMACH Seiko Co., Ltd., gave a keynote report on "Research History and Technology Development Trend of China's Cubic Boron Nitride Abrasives"
According to the report "China's cubic boron nitride abrasives research process and technology development trend": In the past 50 years, China's cBN abrasive industry has experienced a development process from scratch and from small to large. After several generations of technical staff's hard work, a series of landmark cBN abrasives research and development projects have been carried out, and the manufacturing technology of cBN abrasives, which are the four major binders of ceramics, resin, sintered metal and electroplating, has been developed. The internationally competitive cBN abrasive products have achieved fruitful results.
With the rapid development of China's national economic construction, especially the promotion of "Made in China 2025", cBN abrasive tools will be vigorously developed and promoted. At the same time, with the continuous emergence of new difficult-to-machine materials, the continuous improvement of processing requirements, the continuous development of processing technology, and the increasing focus on energy conservation and environmental protection, the cBN abrasive industry will usher in a better development opportunity.
The advantages of cBN grinding tools will be further utilized and utilized. New technologies and new products will continue to emerge, and the application fields will continue to expand and expand. The industrial scale of cBN abrasive tools will be further expanded.
The development prospects of the cBN abrasive industry are bright!

Lu Zhi, Dean of the Guilin Institute of Mineral Geology, China Nonferrous Metals, gave a keynote report on "The History, Current Status and Prospects of PCBN Materials in China"
"China's PCBN material tool history and current situation and prospects" report said: At present, domestic high-content PcBN material technology is relatively mature, and has little difference with similar foreign products, and has been recognized by the market in processing cast iron, powder metallurgy, high-temperature alloys, etc. . However, when processing hardened steel, the comprehensive performance (strength, wear resistance, chemical abrasion resistance) of the tool material is high. There is still a big gap between the current domestic products and foreign countries, and the market for processing hardened steel accounts for PcBN tools. More than 50%, so it is imperative to improve the processing of low-content PcBN materials for quenched steel.
On the afternoon of the 10th, the meeting also arranged a number of technical reports on cubic boron nitride and other aspects.

"Research progress of single-layer cubic boron nitride superabrasive grinding wheel"

"Experimental study on wear state of single cBN abrasive grinding process"

"Effect of filler on the properties and structure of ceramic bond CBN grinding wheel" and "Influence of sintering temperature on the performance of ceramic cBN grinding wheel binder"

Preparation of titanium-aluminum-carbon ceramic bond cBN composite material by self-propagating high-temperature sintering

《PcBN Sintered Body Bonding Agent Optimization Study》

It can be prepared by directly crushing natural calcite, limestone, chalk, shell, etc. by mechanical methods (using Raymond mill or other high-pressure mill). Because the sedimentation volume of Heavy Calcium Carbonate is smaller than that of Light Calcium Carbonate, it is called heavy Calcium Carbonate.
