A series of new changes and new difficulties, such as the overall shrinking market size, rapid upgrading of demand structure, overcapacity and rising costs, have made the machine tool industry, which has entered the downtrend channel since 2012, unable to shake off the downturn. At the 2014 International Forum on Machine Tools and Tools Manufacturing sponsored by China Machine Tool Industry Association, dozens of industry leaders from home and abroad gathered to discuss how to meet the new future of industry development in a new and changing environment.
“The machine tool industry is facing a severe situation, and the development environment is undergoing significant changes in many aspects.†Chen Huiren, executive vice president of China Machine Tool Industry Association, pointed out that on the one hand, the total market demand has dropped significantly, and the industry’s 10-year firestorm growth has ended. In the rational; second, the demand structure of machine tool tools has rapidly increased, and the demand for high-precision, high-speed, high-efficiency and intelligent medium-to-high-end CNC machine tools has increased significantly. Compared with the past, “required higher and more demandingâ€.
According to data from China Machine Tool Industry Association, in the first three quarters of last year, the cumulative import value of machine tool products decreased by 19.3% year-on-year, of which metal processing machine tool imports decreased by 24.0%, and Jinqie machine tool imports decreased by 25.7%. In 2009, affected by the global financial crisis, the import volume of machine tools reached a double-digit drop for the first time in the past 10 years.
A large number of domestic companies are not prepared to deal with these changes. Taking the small-cutting machine industry as an example, the statistics of the key enterprises of the China Machine Tool Industry Association show that from January to November last year, when the sales revenue decreased by 7%, the total profit decreased by 82.1%, and the sales profit margin was only 0.65% indicates that the business situation of the company has deteriorated, the profit level has dropped significantly, and some enterprises have been at a loss.
"Transformation and upgrading has been said for many years and has achieved remarkable results, but it has not yet achieved a fundamental breakthrough." Chen Huiren said that some enterprises are still accustomed to the past administrative means to promote transformation and development, but the situation has changed now, and the future industry transformation will rely more on it. Market forces are coming down.
It should also be noted that some industry benchmarking companies have achieved initial results in the transformation and upgrading under the new situation through solid efforts in innovation and service. Following the order of five large-scale stamping production lines in Ford Motor's two US factories in 2011, the sixth large-scale press line project won by Jinan No. 2 Machine Tool shows that the international competitiveness of some machine tool companies in China is also constantly improving.
"The development under the new situation requires new ideas." Long Xinyuan, chairman of Qinchuan Group, combined with Qinchuan's development experience, said that it is necessary for industry players to analyze the cost structure clearly. At the same time, the business structure must correspond to the cost structure. In addition, the business structure It is necessary to respond well to the market structure, especially the international market. On the one hand, it adheres to its own superior products. On the other hand, it combines its own characteristics to enter into some market segments where competition is not particularly fierce.
Participants also expressed concern about the current industry's excess production capacity and the resulting vicious competition. According to the data, in the last round of economic stimulus, the number of enterprises in the machine tool industry has expanded rapidly. In 2011, the number of metal cutting machine tools was 1,070, and the output was about 400,000. By 2013, it had reached 1,264, an increase of 18.1%. The output can reach 850,000 units, an increase of 112.4% compared with 2011.
“The production capacity is really too big, it is difficult to see hope.†Long Xinyuan quoted the history of the US machine tool industry as saying that there are more than 500 companies in the most prosperous period of the US machine tool industry, but now there are only a few dozen, and there are really scales. No more than 10 homes. He reminded companies in the industry to face up to the status quo of the industry and to make early plans for transformation in combination with their own reality.
According to industry insiders, with the further blurring of domestic and international market boundaries and the technological advancement of domestic machine tools, the mid-end machine tool market has become a hot spot for competition. At the same time, the high-end machine tool import growth has not changed due to domestic high-end demand; The development of line-up equipment, intelligent manufacturing islands, digital workshops, manufacturing services, etc. has not yet formed a scale advantage, which will be the goal of China's machine tool industry to face new changes and create a new future.

High Pressure Tubing
A high pressure tube is a tube that can withstand pressure. It is used to transport the liquid. There are many kinds of pipes, such as steel tubes, copper tubes, stainless steel tubes, and so on. High quality carbon structural steel and alloy structural steel high pressure pipe are mainly used for manufacturing steam boilers and pipes with high pressure and above pressure.
High pressure Steel Pipe and stainless steel seamless steel pipe, these boiler tubes work under high temperature and high pressure, and the pipe will be oxidized and corroded under the action of high temperature smoke and steam. Therefore, the steel pipe has high lasting strength, high oxidation resistance and good organization stability.
The high pressure pipe occupies an important position in the development of the steering pipe of the hydraulic power steering system.
Steel number is: high quality carbon steel steel steel number 20G, 20MnG, 25MnG; alloy structural steel steel 15MoG, 20MoG, 12CrMoG, 15CrMoG, 12Cr2MoG, 12CrMoVG, 12Cr3MoVSiTiB, etc.; rust resistant steel commonly used 1Cr18Ni9, 1Cr18Ni11Nb high pressure pipe in addition to chemical composition and mechanical energy, to do water pressure test, to make expansion. Oral and flattening tests. The steel pipe is delivered in heat treatment state.
In addition, the microstructure, grain size and decarburization layer of finished steel pipe also have certain requirements. Seamless pipes for geological drilling and oil drilling and control are used for drilling underground wells in order to ascertain the structure of underground strata, underground water, oil, natural gas and mineral resources.
The exploitation of oil and natural gas can not be separated from the drilling, and the geological drilling and controlling of the seamless steel pipe used for oil drilling is the main equipment of the drilling, which mainly includes core outer tube, core tube, casing, drill rod and so on.
