On August 1, co-sponsored by the Superhard Materials Branch of China Machine Tool Industry Association and the Production Engineering Branch of China Mechanical Engineering Society (in the field of abrasive grain technology), "Diamond and Abrasive Engineering" magazine, Chongqing University School of Mechanical Engineering, Brittleness The "2020 Extreme Grinding Technology Seminar" jointly organized by the National and Local Joint Engineering Research Center of Material Product Intelligent Manufacturing Technology and the State Key Laboratory of Superhard Materials Abrasives has entered the second day of the agenda. Guests yesterday (July 31) The report aroused widespread concern. Today, eight heavyweight guests appeared in sequence. They focused on the theme of the conference from multiple fields, multiple disciplines, multiple perspectives, and multiple dimensions, and dedicated a splendid audio-visual feast to the participants.

       In the afternoon, the participants visited Jinkang New Energy Automobile Company and Chongqing Sanmo Haida Grinding Machine Co., Ltd. successively.

       The conference completed its various agendas and was a complete success.

       postscript:

       Affected by the prevention and control of the new crown epidemic, especially the global epidemic is still spreading, the superhard materials and abrasives industries suffered heavy losses in the first half of the year, coupled with the drag of the trade war and the complex and changeable global political situation, industrial development and business operations are facing huge challenge. With the effective control of the epidemic in my country, the domestic economy, including the manufacturing supply and demand, is continuing to pick up. Statistics show that as of July, the manufacturing PMI has been in the expansion range for 5 consecutive months; the automobile manufacturing industry production and operation activity expectation index has been higher than 60.0% for two consecutive months, and the performance in the second quarter is "exceeded expectations"; The added value of the manufacturing industry led the regulatory industry by 5.9 percentage points, and investment increased by 5.8% year-on-year, maintaining a positive growth for two consecutive months; the added value of the electronic information manufacturing industry increased by 5.7% year-on-year, of which June increased by 12.6% year-on-year. A year-on-year increase of 2.2 percentage points.

       At present, the overall shrinkage of the market volume is an objective reality, which will bring fiercer competition among enterprises. From the recent series of interviews with China Superhard Materials.com, we can see that technology flow companies are relatively less impacted and their production operations are relatively stable. The performance of some of these companies is even impressive. These companies either have strong technical strength, excellent product quality, or advanced technical level, leading the way, and can provide users with high-quality service solutions. In recent years, as the pace of industry transformation and upgrading has accelerated, the competition among enterprises in the industry has gradually deviated from price competition, returned to technology itself, returned to quality competition, competed for cost-effectiveness, and competed for service. The impact of the new crown epidemic on the economy has accelerated this process. In the post-epidemic era, companies will rely more on technological innovation to maintain their competitive advantage.

       Recently, the central government has made new arrangements for economic and social development—accelerating the formation of a new development pattern in which domestic and international cycles are the mainstay and the domestic and international dual cycles promote each other. This setting emphasizes the domestic cycle, the expansion of domestic demand as a strategic basis, the strategic direction of adhering to structural adjustment, and the need to rely more on technological innovation to lead and promote economic development. my country has an independent and complete industrial chain system, but some key core technologies are still controlled by others, and many industries are still at the low end of the global industrial chain and value chain. In the face of the current complex international situation, this requires the industry to climb to the high end of the global industrial chain and value chain, overcome the excessive dependence of key technologies in the industrial chain on foreign countries, and enhance the supply and supporting capabilities of my country's various industrial chains.

       As a basic manufacturing industry, the superhard materials and abrasives industries play an important strategic supporting role in the supply and supporting of the industrial chain. The new arrangements made by the state for economic development require more technological innovation in the superhard material and abrasives industries. It includes two directions. One is to rely on high-end technology industries to carry out independent design and independent research and development of related supporting products. For example, supporting products for industries such as chips and semiconductors. The second is the upgrading and innovation of the industry from low-end to mid-to-high end, such as technological innovation of conventional products related to new infrastructure. In the face of complex situations, only by insisting on technological innovation can we ensure that enterprises have strong internal motivation; in the face of difficulties and obstacles, only by riding the wind and waves and moving forward can we inspire new vitality in the industry!
