Ha Yigong passed the technical reform of the national debt (invested hundreds of millions of yuan in two years), built a new factory, invested in new equipment, and changed its face. Especially in the fist product broach, the introduction of foreign advanced CNC broach grinding machines and testing instruments, in order to continue to lead in the country, and the traditional advantages of CNC tools such as indexable tools and gear hobs have been further strengthened. The hard alloy arc bevel gear milling cutter and the newly developed CNC cylindrical gear forming milling cutter have been successfully applied and have been well received by users.
Zhuzhou Diamond Cutting Tool Co., Ltd. has invested 1 billion yuan in recent years. It has introduced complete sets of advanced manufacturing technologies and equipment to enable product development capabilities in the fields of solid carbide tools and CNC indexable inserts including carbide materials and CNC tools. And the quality of manufacturing has been greatly improved, becoming the hard-wearing CNC tool/indexable insert manufacturer with the strongest domestic competitiveness, the largest investment in research and development, and the largest production scale.
2. In accordance with the trend of the development of the tool industry, expand the upstream and downstream extension technology and product areas. In order to better meet and adapt to market/national development needs, lay the foundation for the realization of corporate strategic development goals.
Based on the manufacture of hard alloy raw materials and semi-finished products, Zhuzhou Diamond has expanded into the deep processing field of CNC tools and indexable inserts, and has become the largest manufacturer of carbide tool/blade in China. The Shanggong plans to develop from tool manufacturing to tool material (hard alloy) manufacturing, high-grade CNC tool manufacturing equipment manufacturing, etc. The goal is to build a leading large-scale comprehensive metal cutting tool manufacturer in China, integrating tool research, manufacturing and One of the leading domestic companies in service.
3. Focus on basic, commonality, key technology research and development, actively undertake national and local scientific and technological research projects, establish a research and development system for “production, study and researchâ€, and rapidly enhance the innovation capability and technology/product advantages of enterprises.
In recent years, the amount of research and development funds has accounted for more than 4% of sales revenue, and more than 30 new products have been developed and 165 patents have been issued. In 2005, he undertook the drafting of the “HSK Tool Cone Measuring Tool†standard for the National 863 Program. In 2006, he undertook the Harbin “Research and Application of HSK Tool System for High-speed CNC Machine Toolsâ€. In 2007, it undertook the formulation of the national standard “tool pre-adjustment measuring instrument†and the scientific and technological research project of Harbin “CNC and CCD automatic aiming high-precision tool pre-adjustment measuring instrumentâ€. In recent years, Shanggong has undertaken the Innovation Fund of the Ministry of Science and Technology of the People's Republic of China, “Development of Precision Composite Hole Machining Tools and High-efficiency Composite Coating Tools for Automobile Manufacturing Industryâ€, Shanghai Economic and Technological Research Project “Computer Platform Construction for Tool Research and Development†and “High-speed Cutting Coating Toolsâ€. The research and development", "high-efficiency precision CNC tool manufacturing and application technology", etc., obtained a number of patents for tool coating.
4. Through the acquisition of mergers and acquisitions, professional talents and technology introduction, the integration of resources will be optimized and the overall strength of the enterprise will be improved.
Haliang successfully merged with German Kaishi Company in 2005, and laid the manufacturing and development technology and capability for mass production of international level HSK tool system and CNC tool pre-measurement measuring instrument. Shanggong relied on Shanghai Jiyou Co., Ltd. to list in Hong Kong, raised funds, and invested heavily in “developing CNC tool production technology transformation project†in 2007. Through the company with the Italian company SU company, the introduction of advanced gear The tool manufacturing process and know-how have enhanced the manufacturing strength of gear cutters.
Through research, we feel that the tool industry's technical level and production scale have been rapidly developing and progressing, and we also see that the gap with foreign advanced level is still very large. In the energy equipment manufacturing industry such as wind power and nuclear power, the numerical control tools and measuring instruments used in the cutting of key components are almost exclusively monopolized by foreign products. The main manufacturers are Sandvik, Kenner, Isca, Secco and so on. Domestic tools are mainly used for non-critical parts and rough and semi-finishing processes. Compared with foreign products, in addition to the large gap in cutting performance indicators, the bigger problem is that the quality is unstable, unreliable, and the product performance is highly dispersible. In addition, the gap in user services is small.
In China's research, development and manufacturing of CNC cutting technology and CNC cutting tools, the main gaps with foreign countries are reflected in the following three aspects:
(1) Basic theory and technical aspects of CNC cutting, especially microscopic quality control technology, metallographic structure analysis and quality control technology related to materials discipline, and in-depth research on cutting mechanism and technology of new difficult-to-machine materials.
(2) CNC tool manufacturing technology and equipment, especially in the key manufacturing process and process stability to quality control, such as ultra-fine grained carbide substrate, coating process quality control, superhard tool edge reinforcement technology Etc. Equipment: development and development of CNC tool grinding machines, edge strengthening equipment and coating equipment.
(3) CNC tool application technology and experimental research, for different industries, user needs, especially new difficult-to-machine materials such as high-temperature alloy, titanium alloy, silicon-aluminum alloy, composite materials and other workpiece processing, to provide users with scientific, reliable and practical Information platform for feasible CNC tool/indexable insert and cutting database for cutting parameters.
