In the first eight months of this year, China's machinery industry realized a profit of 1.14 trillion yuan, an increase of 14.12% over the same period of last year. In terms of import and export, machinery exports reached 272.7 billion U.S. dollars in 2016 with a total amount of 374.8 billion U.S. dollars with a surplus of 102.1 billion U.S. dollars. Beautiful, but the 'old mechanical industry', China Machinery Industry Federation Special Adviser Tsai Weixi but happy not up.

'Bolts are fasteners for connecting parts, but small bolts require almost 100% import on high-end equipment in China Why?' At the Smart Manufacturing Development Symposium on October 28, the National 973 Project Chief Scientist, China Academy of Engineering Tan Jianrong, Cai Wei Ci from different angles to answer this question.
October 28 held in Jinan, the smart manufacturing development seminar, Tsai Wei Tsai told Science and Technology Daily reporter: 'low-voltage electrical appliances, fasteners, bearings and other large amount of large-scale basic components and parts exports in large quantities, but the high-end products But it must be imported. "In almost every small industry, there is a reality that large quantities of low-end products are exported and high-end products have to be imported in large quantities." He believes that among the five major projects that China Made 2025 has deployed, The strong industrial base and innovation-driven hardship remain the major constraints on the weak and weak foundations for innovation in the machinery industry from strong to strong.
Tan Jirong, the chief scientist of the National 973 Program and academician of the Chinese Academy of Engineering, paid attention to this issue from another perspective. The precision machining of key parts such as high-precision and large-size needs high-end forging machine tools, which are also the basis for major projects. However, High-precision, deep drawing, ultra-low speed and other extreme conditions increase the demand for independent design and development of China forging machine tools are facing difficulties.
He listed a set of data: In 2016, the trade deficit of China's metalworking machine tools was 4.5 billion U.S. dollars, the instrumentation deficit was 12.6 billion U.S. dollars, the auto deficit was as high as 33.8 billion U.S. dollars, and the high-end supply contradictions were outstanding. Japan, which is widely used in the stamping of small precision parts processing equipment, 8K stroke 100KN pressure under the slider up to 4000 times per minute, while the maximum speed of our products only 1200 times per minute.More macro fact, Europe and the United States forging machine digital control rate of up to 80%, while China is less than 30%.
Cai Wei Ci believes that 'Made in China 2025' requires high-quality manufacturing not only depends on the management, but also depends on a high level of basic manufacturing support. 'Without a high level of basic components, basic materials, basic processes and basic machinery support, Can not change the image of China's' low-end goods', 'he said.
However, the gratifying is that some key enterprises keep pace with the times, continue to solve the above problems.No matter is Tan Jianrong or Cai Wei Ci mentioned a state-owned enterprises - Jinan Machine Tool Group.In the 1950s China's first planer, the first Mechanical presses for the start, 'Chi II' has developed more than 450 kinds of China's first (sets), took 11 major national science and technology projects, large-scale stamping prepared for the domestic market share of 80% until the world's three major data One of the punching equipment providers.
'Jinan II machine tool is a banner of China's machine tool industry, but also rare in the machine tool industry evergreen tree, they rely on independent innovation, service-oriented manufacturing and open development to the outside world shows a traditional machine tool backbone enterprises from big to strong , Becoming the industry leader in the process. 'Tsai Wei Ci said that this is a case worth learning.
