Now in the world's machine tool industry, the United States is still the world's superlative level. Overall, throughout the 20th century, the United States was always ahead, but in the 1970s and 1980s, Japan's technology caught up with the level of the United States. But the United States machining aspects of the heritage has not been lost, in the 21st century and the emphasis on machining after the technology has been formed to Japan's backward, at least with Japan to maintain the level of neck-and-neck.
Representative U.S. machine tool companies are: Gleason Gleason machine tools (a leader in the field of gears); Haas machine tools (CNC machine tools); Hardinge Harding machine tools (lathes and fixtures).
For the US aero-engine sector, probably the most important is this Hardinge machine tool. It is the world's small and medium-sized machining market leader, almost 80% of the market share in Europe and the United States, in the military field of application in particular. Europe and the United States in the military field of small precision machining almost all of this machine tool factory round.
In 2013, Hardinge also built a factory in Jiaxing, China, to produce HG series of high-precision internal and external cylindrical grinding machines. So far, it can be concluded that the level of machining in the United States is still superb, and can not become aero-engine manufacturing short board. At least, Europe and the United States in the military field of small and medium-sized metal machining, all Hardinge Harding machine tools in the provision of disguised confirmation, even if the U.S. aero-engine has a shortcomings, but also will not be in the machining.Aero-engine high-end machine tools are just one aspect of advanced aerospace materials and processing technology is high-end. More to do with the strong high-end industrial base.
The U.S. high-end machine tools are not undeveloped but very developed! "Marg, Berlin . Ger, Xingxin Nati, Haas, Harting" and so on, these machine tool big brother is in the international machine tool industry, the existence of the famous. Whether in aerospace, automotive, or any other field, the U.S. has a full range of high-end machine tools to meet your needs. At the same time, U.S. manufacturers in many countries around the world have production bases, and merged with some machine tool companies, including Germany. We usually only know Germany, Japan, Switzerland machine tools, but the United States machine tools are also known throughout the world.
The basic judgment is wrong, the United States of America's high-end machine tools are very developed, can be said to be superb level. In the high-end manufacturing industry, the U.S. product capabilities, market share, technological advancement are the highest in the world. We often see Germany and Japan's high-end machine tool ads, those are their exports, more advanced than ours, and the source in the United States.
The United States in the field of core technology investment is much higher than the rest of the world, on the one hand, to ensure the leadership of its products, on the one hand, advanced products sell high prices, and feedback to the field of research and development. In this regard, the accumulation of the United States is the most profound, and the business model has formed a closed loop. That is to say, the entire upstream advanced technology supply of developed countries, almost all rely on the United States. This invisible market does not directly face the consumer, for the industry outside the general public do not understand.
The aero-engine is the crown jewel of industrial manufacturing. In addition to high-end machine tools, the United States is at the forefront of the world in all aspects of precision industrial design, advanced materials science, and industrial computer applications. China wants to catch up with the United States, there is indeed a long way to go. In this regard, we should not be too inferior, nor can we be arrogant, the gap is very obvious.
Therefore, to catch up with the U.S. capabilities, we need to have good scientific research capabilities on the one hand, and on the other hand, we need to have enough market docking capabilities, in the U.S. full blockade, China's ability to rise is difficult. However, difficulties will always be overcome and problems will always be solved. I believe that after a while, China can catch up with the United States in this regard, the formation of their own technological leadership.
CNC machine tools is originally the Americans came up with, whether it is the Cartesian coordinate system or virtual axis system machine tools, the Americans are far ahead. The public casually talk about two:
Gleason machine tools, surface machining, the king of gear technology.
The first five-axis machining center creator Cincinnati, Mitsubishi Heavy Industries key parts manufacturing only with Cincinnati machine tools, Rollo aero-engine combustion chambers, the Musk Dragon spacecraft propulsion can not be separated from the Cincinnati.
Heck, the world's leading intelligent CNC machinery, waterjet machining in the exclusive leader.
Good Energy's CNC honing machines are also among the best in the world.
The United States is very underdeveloped, f35, Nimitz is hammered out with a hammer.
Say that again?
The world can produce the highest-end machine tools in the country, none of them are U.S. allies, they produce machine tools are to sell money, hostile and unfriendly countries can not be sold, if the United States also do not sell, they sell to whom? If the U.S. won't sell them, who will they sell them to? I'm afraid I want to charge more expensive also dare not, so the United States does not lack of high-end machine tools.
A lot of German scientists were brought to the US after WWII.
Now the quality of national products is very good!!!
