General Manager of Shanghai Yuhe Diamond Tools Co., Ltd. Nie Fengyao
1. What are the advantages of superhard tools? How to look at the market prospects of superhard tools?
Nie Fengyao: The hardness of superhard tools is harder than ordinary high speed steel, carbide and ceramic tools, and the tool life is longer and more durable. In terms of classification, superhard tools can be divided into single crystal (ND) diamond tools, polycrystalline (PCD) diamond tools and polycrystalline cubic boron nitride (PCBN) tools. The difference between them is mainly in processing materials and processing. The accuracy requirements are different. Single crystal diamond tools are mainly used in ultra-precision machining of modern manufacturing fields such as rockets, military, satellite, optical, laser, medical equipment, large telescopes, etc., requiring sharpness of the blade Ï 1 - 0.1μm, flank Ra 0.02μm The edge is tested for at least 500-1000 magnifications for sawtooth-free defects. Polycrystalline diamond tools are mainly used in precision cutting fields such as electronics, IT, and car cutting tools. Nickel-based superalloys and HRC 50 hardened steels, chilled cast irons, etc., we generally use PCBN tools, of course, there are many tool geometry and manufacturing process changes, the resulting cutting results are generally not the same.
With the development of the material industry and modern precision manufacturing, the use of precision cutting, ultra-precision cutting, micro-cutting and difficult-to-cut materials has increased, and the application of super-hard tool materials has become increasingly widespread. Due to its high work efficiency, long service life and good processing quality, superhard material tools have been mainly used for finishing. In recent years, due to the improvement of the production process of artificial superhard tool materials, the purity and grain size of raw materials have been controlled. The use of composite materials and hot pressing technology, the application range is expanding, in addition to general finishing and semi-finishing, can also be used for ultra-precision and micro-machining, using ultra-hard materials to process steel, cast iron, non-ferrous metals Parts such as alloys.
2. At present, there are many superhard tool companies in China? What are the advantages of your company in the fierce competition in the industry?
Nie Fengyao: According to the equipment and production rhythm of the customer, Yuhe can provide customers with a total solution. The tool industry is a service industry, the tool service is perfect, and the efficiency of the entire machining industry will be greatly improved. Yuhe and Hebei Laser Research Institute have established a new product development and application platform, hoping to control from raw materials, research and development to adapt to the modern development of the machinery industry, the most advanced single crystal diamond tools in China. Improve the ability of our nation to produce, develop and innovate.
Yu and the second advantage are the talent training mechanism and new product development plan established with Peking University, Shanghai Polytechnic University, Wuhan University of Geosciences, Beijing University of Science and Technology, etc., which provides a strong guarantee for the high-precision diamond tool manufacturing. In 2013, Yuhe relied on a full set of modern advanced processing equipment and professional precision measuring instruments imported from abroad, and cooperated with all universities to lay a solid foundation for new product development. Through the platform of Shanghai University of Technology, we carry out scientific analysis and in-depth study on the basic theory of the cutting mechanism of single crystal diamond tools, and use computer simulation cutting technology to design some single crystal diamond tools. I hope that diamond tools can be used to cut different materials in the future. database. When China's own large database of cutting is completed, it will be a cause for China's manufacturing merits, which requires the joint efforts of several generations. The third advantage is the strengthening of the construction of the workforce and the cultivation of talents. The company has externally hired professional professors from Tongji University and regularly trains employees. In terms of talent management, Shanghai Yuhe dares to introduce excellent talents. There are clear standards for each position. As long as the talents who meet the standards are actively introduced, they will provide a fair and just platform. According to the company's assessment system, each employee is assessed, and the rewards and punishments are clearly defined. The management personnel will be reviewed on a regular basis to continuously improve the management level of the administrator.
3, equipment and technology is the basic guarantee of the product, can you introduce the production equipment and technical advantages of your company?
Nie Fengyao: Yuhe Tools is now used in ultra-precision technologies such as military, aerospace, radar, medical equipment, optical lenses, laser mirrors, large-scale astronomical telescopes, high-speed cameras, etc., and will soon be in the optical ultra-precision industry, electronics. The industry has exerted its strength, and now it has introduced, digested and absorbed the most advanced sharpening equipment and testing instruments from the United Kingdom, Japan, Germany, Switzerland and other countries, and we have applied for more than a dozen national invention patents and utility model patents. With unique cutting edge treatment technology, it fundamentally guarantees the quality of the tool.
