Recently, Zhengzhou Abrasives Grinding Research Institute Co., Ltd. (Zhengzhou Sanmo) declared the "Key Technology Development of Lightweight Ultra-High Speed ​​ZLS Based Ceramic CBN Grinding Wheel" project won the special award of Zhengzhou Science and Technology Progress Award. One of the special prizes. This is the first time that the company has won the special award of Zhengzhou Science and Technology Progress Award since its establishment in 1958. The "Key Technology Development of Lightweight Ultra-High Speed ​​ZLS Based Ceramic CBN Grinding Wheel" project starts from the research of basic materials, and systematically integrates innovations in the design of grinding wheel base, bonding agent, abrasive layer, forming method and ultra-high speed grinding wheel. Developed ZLAS self-toughening microcrystalline glass ceramic bond for ultra-high speed grinding, lightweight low expansion coefficient carbon fiber reinforced resin matrix composite wheel base for ultra-high speed grinding wheel, and solved the manufacture of ultra-high speed ceramic CBN grinding wheel The key common technical problems have made a historic breakthrough.
The technical problem of the project solved the weight of the grinding wheel for ultra-high-speed grinding of automobile crankshaft and camshaft, which is one-third of the weight of alloy steel grinding wheel. The grinding line speed is generally 200m/s, which is light in weight, low in cost and grinding. Long life and other characteristics. The overall technical level has reached the international advanced level.
Also: Recently, the project “Development of Non-Processing Ultra-thin Superhard Material Resin Cutting Wheel†declared by Zhengzhou Sanmao Research Institute Co., Ltd. won the second prize of 2014 China Machinery Industry Group Science and Technology Award.
The project solves the key technology of the manufacture of end face non-processed ultra-thin super-hard material resin cutting wheel, and develops a new product of end-face non-processing ultra-thin super-hard material resin cutting wheel and corresponding manufacturing technology.
The completion of the project has achieved breakthroughs in the complete manufacturing technology of non-processed high-precision ultra-thin and ultra-hard material resin cutting wheels; in the technical aspects of ultra-thin grinding wheel precision press molding, special formula design, and non-deformation internal and external precision machining. It has filled the domestic gap, narrowed the gap with the international advanced level, and ended the history of dependence on imports of such products in China. At the same time, it will improve the manufacturing level of China's super-hard material cutting wheel products, promote the technological progress of the industry, and lead the development direction of domestic high-precision, high-efficiency super-hard material products, which has played a demonstration role in the adjustment of the industry product structure. It is of great significance to guide the development of China's superhard material products industry to high-precision, high-efficiency and complete sets of technology. (Correspondent Zhang Geqi)
