Zhuzhou Cemented Carbide group company's "Research on industrialization technology of key raw materials of high-performance cemented carbide and shield cutting tools" has recently been reviewed and approved by the expert group of the national science and technology support plan. Shield machine is a special engineering machine for tunneling. It is recognized as a ring block friction and wear testing machine that evaluates the lubrication performance of various lubricants and fails after a while. It is a national equipment 2 According to the experimental time, it can be divided into long-term and short-term experimental mechanisms, which are major key equipment of manufacturing level and ability. The shield cutter is the "tooth" of the shield machine, which determines the quality, efficiency and cost of shield construction. However, at present, shield cutting tools are almost monopolized by foreign brands
