Recently, the project of “High-efficiency precision indexable tool series and super-hard tool” led by Zhuzhou Diamond Cutting Tool Co., Ltd. passed the acceptance test at the user site – Xi’an Aerodynamics Co., Ltd. The team leader of the project acceptance was chaired by Yang Jingyan, a researcher at the Beijing Machine Tool Research Institute. At the meeting, Zhuzhou Diamond, Central South University, Huazhong University of Science and Technology and other leading and participating units reported separately. Tool users FAW-Volkswagen Automotive Co., Ltd. and FAW Mould Manufacturing Co., Ltd. The company and Xi'an Aerodynamics Co., Ltd. introduced product application and test verification.

The subject breaks through the preparation of PVD coatings such as nanocrystalline/amorphous composite coatings, (Ti, Al)N/TiN nano-multilayer coatings, gradient matrix and ultra-fine crystal matrix, and double-coil cooling holes that can be indexed shallow holes. A number of high-efficiency precision indexable tool manufacturing core technologies such as drilling preparation, 23 patents granted, and 1 application for industry standards. The project has developed 14 series of tool grades such as YBD, YBC, YBM and YBG, and 31 series of tool models such as car, milling and drilling. It has passed the test of National Tool Quality Supervision and Inspection Center, and some products have reached or exceeded the similar products abroad. Improve the technological content of domestic high-end tools. The results of the project have been applied in key industries such as China First Heavy Machinery Group Corporation, China Second Heavy Machinery Group Corporation, FAW-Volkswagen Automotive Co., Ltd., Xi'an Aerodynamics Co., Ltd. and FAW Mould Manufacturing Co., Ltd. .

The implementation of this topic has effectively promoted the competition between domestically produced high-efficiency indexable tools and foreign high-end tools. It has the ability to replace foreign tools in the development of general-purpose machining tools for cast iron and steel materials, and the supporting level and supporting capacity have also been improved. At present, Zhuzhou Diamond Cutting Tool Co., Ltd. has formed an annual production capacity of 50 million pieces of high-efficiency indexable tools, and has made great contributions to improving the market share of domestically produced tools in China.

Cnc Plasma & flame cutting machines combine plasma cutting and flame cutting in one machine. 
1. Plasma And Flame Cutting Machine can improve production efficiency and ensure the cutting of plates of different thicknesses. 
2. Plasma and Flame Cutting Machine can cut all kinds of carbon steel plates with flame, and can cut stainless steel, aluminum, copper and other non-ferrous metal plates with plasma. 

3. CNC plasma and flame cutter is the best choice for engineering machinery, shipbuilding, automobile, pressure vessel, steel structure and other industries.
