Abrasives branch of China Machine Tool Industry Association through the exchange of cimt2021 exhibition, we found that, as an important upstream link of the machine tool industry, the abrasives industry was greatly affected by the epidemic in 2020, and most domestic Abrasives enterprises had poor production and operation conditions. In the face of challenges, enterprises have made concerted efforts to meet difficulties and achieved good expected results in innovation driven, quality improvement and efficiency increase. Since the fourth quarter of 2020, the operation of the industry has generally improved, and the order volume and product price of enterprises have increased steadily. However, enterprises lack key core technologies and & ldquo; Stuck neck & rdquo; Technical problems, high-end products are mostly imported and other phenomena still exist. 2021 is & ldquo; The 14th five year plan; At the beginning of the year, enterprises generally realized that in the face of increasingly complex and changeable market environment and & ldquo; Double cycle & rdquo; The development pattern of the industry, focusing on innovation driven, transformation and upgrading and achieving high-quality development goals, needs to adapt to the new requirements of the development of China's manufacturing industry and strive to improve the international competitiveness and sustainable development ability of the industry in recent years, domestic abrasive enterprises have increased product R & D efforts. Through the application of ceramic microcrystalline abrasive, calcined abrasive, plated abrasive, magnetic abrasive and low-temperature binder technology, some products are close to or can replace foreign high-end products in performance a key word of cimt2021 is integration, including the integration between machine tools and abrasives, the integration between host manufacturers and component manufacturers, the integration of collaborative innovation between industry, University and research, and the mutual integration and common development between upstream and downstream industries, enterprises, technology and market. At the same time, cimt2021 focuses on the most cutting-edge technology and the latest development achievements of the intelligent development of machine tool manufacturing industry. From the classic digital solutions to the new generation of intelligent products and technologies deeply integrated with the most cutting-edge information technology, the audience can fully appreciate the infinite creativity in the era of intelligent manufacturing and feel the future & ldquo; Smart & rdquo; Unlimited possibilities domestic abrasive tool enterprises demonstrated on cimt2021 with & ldquo; High efficiency, precision and high speed & rdquo; As the main characteristic abrasive products, they mainly include ceramic microcrystalline abrasive tools, tool grinding, gear grinding, strong grinding, roll grinding, crankshaft grinding, special grinding wheel for plane gear in aerospace field (for Ti alloy low-density and high-strength hard grinding materials), UB grinding wheel, paper slurry polishing wheel, be ball pore double face grinding wheel, non-woven grinding wheel, CBN diamond grinding wheel Ceramic microcrystalline corundum and other high-end products, as well as high-grade abrasives and abrasives for high-speed rail grinding, special steel stainless steel, national defense equipment and so on
