"Our stamping process equipment does not require imports, and the level of technology is already equal to that of industrialized countries." Dai Rongju, chief engineer of the Jinan No. 2 Machine Tool Group's automatic company, told reporters recently.
Everything is not easy. "Now the domestic high-end CNC machine tools basically need to be imported, and there are basically no machine tools that can be exported to foreign countries." Prof. Yusheng Yu, a national-level CNC machine tool expert, stated that "mainly the technical level of the two parties is quite different."
However, under the background of accelerating the development of high-end equipment manufacturing industry in the country, China's machine tool manufacturers headed by Jinan No. 2 Machine Tool Group have already seen the spring of industry development and have begun to make every effort to produce more high-end machine tool products and change China’s industrial Fall behind.
Jinan No. 2 Machine Tool Group Leads Breakthrough "Now China is already the world's largest consumer of machine tools, but domestic machine tool companies produce low-end products, which may produce more than 100,000 units per year, and import 10,000 high-end machines every year. Therefore, the foreign exchange spent on imported high-end machine tools has already reached the output value of domestic low-end machine tools." Professor Yu Shengmei told the reporter of "Daily Economic News".
Obviously, after the country has included the high-end equipment manufacturing industry in the seven strategic emerging industries, participating in international competition and trying to win has become a goal that domestic enterprises are eager to rise. The Jinan No. 2 Machine Tool Group is also trying to do so.
Zhang Zhigang, chairman of Jinan No. 2 Machine Tool Group, went to Beijing for a report and referred to the company's high-speed stamping line project. The project was participated by the National Development and Reform Commission, the Ministry of Science and Technology, and the Ministry of Industry and Information Technology. It was organized by the national “High-end CNC Machine Tools and Basic Manufacturing Equipment†major science and technology implementation management office, and reported to the responsible officials of the State Council and relevant ministries and commissions on the implementation of major scientific and technological projects. There are 4 companies in total. Business participation. In the report, Zhang Zhigang was the only one of the four reporting units. The reporting time was extended from the originally scheduled 8 minutes to 15 minutes. The reason was that during the reporting process, Jinan No. 2 Machine Tool Group became the only company to receive interviews from the leaders. "The enterprise," said Wan Gang, the minister of science and technology, said at the time that the company's current level of "press line" was not simple and easy, from 12 beats per minute to 16 beats, and the efficiency increased by a quarter, and the quality has also driven the company. â€
Among the six major types of machine tools provided for auto companies, the stamping process equipment of Jinan No. 2 Machine Tool Group is also the only type of equipment that does not require imports. The current market share is about 80%. The large-scale rapid stamping line mentioned in the above report Shanghai GM Dongyue Automobile Co., Ltd. and Chery Automobile also completed installation and commissioning work. "There is basically no machine tool product exported to foreign countries. The reason is that the technical level is not reassuring." Yu Shengmei told reporters.
However, Dai Rongju said: “When some joint-venture companies of international auto companies in China are making relevant tenders, we are the only company in China that is qualified to participate in bidding. In the competition with foreign companies, they often succeed in winning the bid. The level of technology has been equal to that of industrialized countries."
Dai Rongju refers to the machine tool products for auto manufacturers. “Our products mainly supply auto companies, but they basically cover different levels of demand,†says Dai Rongju.
Lu Jiansheng, deputy general manager of the Jinan No. 2 Machine Tool Group, said in an interview with People's Daily that "at present, there are about 7 or 8 vehicles in the 10 vehicles that are manufactured using our equipment." Jinan Science and Technology The Bureau explained that Jinan No.2 Machine Tool Group is currently the largest forging equipment and most comprehensive metallurgical machine tool manufacturing enterprise in China with the largest overall product category and strongest overall manufacturing strength. However, almost all large-scale press equipment used in the production of its own-brand automobile are From Jinan Second Machine Tool, including GM, Honda, Volkswagen and other joint venture brands are also mostly used Jinan Second Machine Tool Group products. "And complete export to the United States, Canada, Germany, more than 50 countries and regions, becoming one of the world's three major stamping equipment manufacturers." Jinan City Science and Technology Bureau said.
"Now there is a gap between domestically advanced high-end machine tools and foreign advanced level products, and this will require further improvement in our technological level," Dai Rongju said.
However, Dai Rongju also pointed out: "After the country releases the relevant plans for the high-end equipment manufacturing industry, the company must also hope to seize market opportunities."
In the news released by the Shandong State-owned Assets Supervision and Administration Commission of the People's Republic of China, the 4000-kilo-bar automated high-speed precision silicon steel sheet production line developed by the Jinan No. 2 Machine Tool Group has successfully passed the pre-acceptance inspection of Dongfang Group Dongfang Motor Co., Ltd. Originally, this kind of product market has been monopolized by foreign companies. The orders obtained by Jinan No. 2 Machine Tool Group came from winning the same stage competition with German and Japanese companies in 2009. This product has reached a higher level in terms of “the structure of the whole machine, the selection of parts, the vibration and noise of the machine tool, and the stamping efficiency,†said Jinan Science and Technology Bureau.
In addition, the company also stated that the production of high-torque mechanical dual-oscillating milling head has also broken the long-term technical monopoly of the developed countries in China, and has been well applied and verified in the processing of the Three Gorges hydropower station blades.
The company’s announcement also stated that since August of this year, it has successively won a series of high-end product orders in international bidding, such as signing single-arm, two-arm feeding fast stamping with FAW-Volkswagen, Shanghai GM, and Jiangling Auto. Lines, large robot press lines, large multi-station presses and other supply contracts show the company's strong international competitiveness.
Machine tool industry compound growth of 25% to 30% in the next 5 years
"The level of the machine tool industry essentially reflects the industrial level of a country." Professor Yu Shengmei said, "CNC machine tools are called master machines for high-end equipment manufacturing, but our country's demand for low-end machine tools is still very large, It is obvious that the industrial level is not as good as that of foreign industrial countries."
“The backwardness of the machine tool industry is caused by various factors.†Yu Shengmei analyzed to reporters. “The technology of China's machine tool industry mainly comes from the help of Soviet technical personnel in the 50s and 60s of the last century, but afterwards due to treatment, etc. The problem is that the loss of researchers in the machine tool industry is very fast and cohesiveness is not enough. Long-term backwardness has caused domestic companies to spend more to buy foreign products and meet their own needs. It will take at least several decades to change this situation. Accumulation."
However, the huge demand for the machine tool industry is close at hand. “Researching machine tool-related technologies must be practical and time-consuming. However, some companies are very short-sighted and wait for orders to be placed this month. The next month’s products will Effective, so they have chosen to buy foreign products, rather than supporting the domestic enterprises." Yu Shengmei said. Under such a background, a large amount of profits have been absorbed by foreign industrial advanced companies. “Even if domestic companies have developed similar products at the same price, domestic downstream industry companies are still willing to choose products from foreign companies and feel that the technology is more mature and more assured. Yu Shengmei told reporters.
The BOCI International report also pointed out that as the world's largest machine tool consumer, the self-sufficiency rate of China's middle and high-end CNC machine tools industry is seriously low, and there is a big gap between the world's advanced countries in design and R&D, materials and processes, and parts and components. . While benefiting the country’s industrial policy, the huge demand of the downstream industry has won precious opportunities for the development of the CNC machine tool industry in China. “Continually increasing consumption capacity and infrastructure development driven by regional revitalization planning have determined the Chinese automobile market and construction machinery. The market will continue to maintain a good growth for a long period of time, which will determine the good prospects for the growth of China's machine tool market," said BOC International in its report.
According to statistics, since 2010, the growth rate of production and sales of the machine tool industry has been over 40%. Galaxy Securities expects that the compound growth rate of the machine tool industry will be 25% to 30% in the next five years, and mid- to high-end CNC machine tools will become the main force for growth. Galaxy Securities explained that “the growth momentum comes from the continuous upgrading of existing products, gaining international market share, and on the other hand, through technology research and development and product innovation, entering the country’s key support product areas and forming new growth points. â€
“The current situation is much better than it was before.†Yu Shengmei said, “Each of the previous studies had very little funding, and during the 12th Five-Year Plan period, the total funding for state-funded CNC machine tools will be Reach 10 billion yuan."
