why? "At present, our machine tools are high-speed, high-quality, high-turning and compound-type machine tools. Good horses need to be equipped with good saddles. However, the phenomenon of high-quality and low-tool configuration in the enterprise is very serious. The tool is the last process, and the tool problem is solved. The problem of the utilization rate of the machine tool has also solved most of it." Xing Min said.
Insiders pointed out that the application level of high-efficiency cutting tools in China's manufacturing industry is still very low, and the potential for improving productivity is huge. At present, the development of CNC tools and measuring instruments in China lags behind the development of CNC machine tools, which has become a bottleneck hindering the development of CNC cutting technology and CNC cutting machine tools in China. It is imperative to change the status quo.
High-end market competition is weak
Since the beginning of the new century, with the large-scale transfer of manufacturing in developed countries to China, the domestic manufacturing industry has also accelerated the pace of technological transformation, so domestic CNC machine tools have begun to enter the manufacturing field. A sharp contradiction quickly emerged from the surface: advanced CNC machine tools, equipped with advanced domestic tools, had to be equipped with "foreign knife." After years of hard work, domestically produced high-efficiency tools have begun to enter this field, but their share is less than 20%. For example, in 2008, China's tool consumption was 29 billion yuan (about 4 billion US dollars), of which imported tools reached 10 billion yuan (about 1.4 billion US dollars), and the market share exceeded 1/3. Especially since the beginning of the 21st century, the consumption of imported tools has increased by more than 30% per year, exceeding the average growth rate of domestically produced tools. Domestically produced tools are being pushed by the steps of imported tools in the high-end market. The main reason is that domestically produced tools have a large gap with developed countries in terms of product structure and quality.
Xie Huaxuan, a researcher at the Chengdu Tool Research Institute, believes that during the “Eleventh Five-Year Plan†period, major projects in China’s manufacturing sector will include important areas such as energy, automobiles, aerospace and transportation, as well as important areas of national economy and people’s livelihood. The typical and key parts involved are: large, heavy, complex and precise, in which the cutting of new difficult-to-machine materials (such as silicon-aluminum alloy, titanium alloy, high-strength heat-resistant steel, carbon fiber and composite materials) A considerable proportion. "This has raised new issues for CNC machining technology and CNC cutting machine tool equipment. It also puts new requirements and challenges on CNC tool and digital measurement technology and measuring instrument, and provides new development opportunities and stage." Xie Huaxuan said .
Technical content highlights the gap
"Through the survey, we feel that the tool industry's technical level and production scale have been rapidly developed and improved, and we also see that the gap with the foreign advanced level is still very large." Participated in the national key points organized by the China Machine Tool Industry Association. After research on equipment manufacturing and tool manufacturing companies, Xie Huazhen felt deeply. He pointed out that 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. 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 dispersed.
A person in charge of the China National Machinery Industry Metal Cutting Tool Technology Association believes that the main problem facing Chinese tool companies is the low level of technology and technology. At this stage, cemented carbide tools have dominated the tool type in developed countries, with a proportion of up to 70%. The proportion of high-speed steel tools has now fallen below 30%. At present, the annual sales of China's knives is about 14.5 billion yuan, of which the proportion of cemented carbide tools is less than 25%, but China's tool companies blindly and mass-produce high-speed steel knives and some low-grade standard knives, with high add-on The high-end tool market with high value and high-tech content has been handed over to foreign companies.
Second is the low added value of the product. Of the 16,500 tons of cemented carbide produced in China, 4,500 tons are used in the production of cutting tools, which is equivalent in quantity to Japan. However, the value of the tool is only 800 million US dollars, far less than Japan's 2.5 billion US dollars, which fully shows that the overall production efficiency of domestic cemented carbide high efficiency tools is still quite different from that of foreign countries.
Seeking breakthroughs in many efforts
In 2009, the state launched the national science and technology major project of “high-end CNC machine tools and basic manufacturing equipmentâ€, with a national investment of more than 2 billion. The rapid development of China's manufacturing industry has provided huge market potential for the development of cutting tools.
According to industry experts, many factories have formulated their recent development policies and long-term development strategies according to their own characteristics, and have carried out the technical transformation implementation stage and achieved remarkable results. However, it is difficult to compete with international big companies in terms of technology and quality. It is necessary to break the limitations of “single fightâ€, closely connect, complement each other and form a strategic alliance to break down. The mid-to-high-end market monopolized by foreign brand companies. As a joint venture with the Italian company SU, Shangyou Machine Tools (Shanghai) Co., Ltd., Hanjiang Tools Co., Ltd. and Blazers Coatings Co., Ltd. jointly established a coating center, and Ha Yigong and the German PVT coating company jointly established a coating center. The cooperation form enhances the competitiveness and market share of the company.
Second, there is still a need to strengthen services. Multinational companies, such as Germany's Xiongke, Japan's Jiejie, Switzerland's Unimog and other tool manufacturers, have accumulated rich production experience in the long history of development, and their service forms surpass the primary sales stage of only providing customers with tools. According to the problems encountered by the customers in the production process, timely solutions are proposed. This advanced form of integrating sales into the production process of enterprises has become the usual sales method for foreign companies. However, due to the inadequacy of services, some Chinese companies are not able to win the favor of customers despite their “large volumeâ€.
Liu Gang, director of the Shanghai Tool Factory Technical Center, said that the improvement of modern manufacturing methods will enable manufacturers to adjust the selection criteria of tools. The choice of high-speed cutting tools will emphasize the overall efficiency of the system, and whether the tool products can meet the production. The flexible requirements of the system will become an important criterion for bulk procurement.

China's efficient tool shortage is in urgent need of improvement
“24% of the domestically introduced $7.5 billion high-end machine tools are used in the automotive and engine industries. After using these high-end equipment, 70% of the faults occur in tools and flexible fixtures.†2009 Automotive Industry Development and Equipment At the manufacturing symposium, Xing Min, chairman of the China Metal Cutting Tools Association, revealed such a ratio.
