What level is Chinese machine tool industry in now? YOU WOULDN’T BELIEVE IT!

The numerical control machine tool industry is an important basic industry which relates to the national strategic position and embodies the national Comprehensive National Power. Its manufacturing level and the quantity it owns are important signs to measure a country’s industrial modernization degree, it is an important basic industry with strategic significance in national defense construction.

Compared with the Western developed countries, we started relatively late in the field of machinery. In the late 1970s and early 1980s, the Western developed countries had fully entered the era of numerical control machine tools, but China’s CNC technology is still in its infancy, in addition to a few simple product categories, so, to the 90’s machine tool market opening, China’s machine tool industry is facing stronger competitive pressure.

So what is the level of Chinese machine tools in China now? Since the beginning of this century, CNC machine tool technology in China began to truly mature, at the same time has been rapidly popularized. At present, in the field of machine tool industry, all kinds of machine tools suitable for using numerical control technology have adopted numerical control technology. Chen Huiren, executive vice chairman of China Machine Tool Industry Association, said: after 40 years of reform and opening up, China’s machine tool industry has made great achievements and great progress, and the industrial capacity and international status have undergone comprehensive and profound changes.

 

In recent years, with the rapid development of equipment manufacturing, China’s heavy-duty machine tools can be described as fruitful, successfully developed a number of the world’s largest CNC machine tools, one by one can be called national treasure grade “made in China” world-renowned.

 

Even more importantly, at the 83rd meeting of the International Organization for Standardization (ISO), the Technical Committee for Machine Tools and the Technical Sub-Committee on Testing Conditions for Metal Cutting Machine Tools, held recently in Salzburg, Austria, Chengfei’s S specimens, which were independently developed for the dynamic machining accuracy detection of high-end five-axis CNC machine tools, entered the international standard sequence, which means that the field of metal cutting machine tools testing has finally been developed by China and accepted by the international general standard.

And this is undoubtedly the biggest recognition, it should be noted that the rise of our country in the relevant manufacturing areas is closely related to national defense construction, our first aircraft carrier was built from that time, and the J-20 began to develop the time, is precisely that time. More “Chinese standards” will inject more Chinese power into the manufacturing industry of the new era, and we will also have high-end weapons and equipment beyond the J-20 and domestic aircraft carriers in the future.

 

In recent years, 20 series as well as various new weapons and equipment have made their appearance continuously, all of which can be attributed to our country’s heavy machine tools, such as: 01, the super-heavy CNC Gantry boring and milling machine made by Beijing No. 1 machine tool works, which has the largest domestic single machine output value, it is also the largest NC Gantry milling machine in the world so far. Known as the “machine carrier, ” the super machine is 15 meters high, 22 meters wide, 39 meters long and 900 tons in weight. It can turn steel parts the size of a basketball court into any shape. It is used to manufacture the low-pressure inner cylinder and high-pressure Outer Cylinder of the megawatt nuclear power plant in China.

 
02, developed by Zhongchuan Heavy Machine Tool Co. , Ltd. , the world’s largest machining diameter seven-axis six-linkage propeller processing machine tool, the largest processing 11-meter diameter propeller. As we all know, the quiet performance of submarines is the core index to measure their combat effectiveness. The noise of Chinese Navy submarines has long been criticized by the outside world. The US military even claims that Chinese submarines can be detected as soon as they leave port. The key part of the noise control is the propeller in the tail of the submarine. The production of the seven-axis and six-axis propeller processing machine will greatly improve the noise performance of the Chinese navy submarine.

 

At the same time, the seven-axis six-link motive bed is the largest and most complex machine tool in the world. The successful development of this machine tool marks that Chinese machine tool enterprises already have the strength to compete with the world machine tool strong enterprises in the international market.

 

03. There is also the world’s largest gear CNC machining equipment, the large-scale gear hobbing equipment with a diameter of 16 meters manufactured by Citic Heavy Industries, which is also the world’s largest and most technologically advanced gear CNC machining equipment, maximum processing diameter 16 meters. It enabled China to master the manufacturing technology of heavy-duty Marine crankshaft processing machine tools, and got rid of the situation that large marine crankshaft was heavily dependent on imports before. China has also become the third country in the world, after Germany and Japan, which can design and manufacture crankshaft processing equipment independently.

Not only that, China No. 2 Heavy Machinery Group has also successfully built the world’s largest die forging hydraulic press, this 80,000-ton die forging hydraulic press, 27 meters above the ground and 15 meters below the ground, with a total height of 42 meters and a total weight of 22,000 tons, is China’s home-made large aircraft C919 flight test success one of the important credits. The giant die forging hydraulic press is a national treasure-grade strategic equipment symbolizing the strength of heavy industry, and an important symbol to measure a country’s industrial strength and military industry ability. At present, the world has more than 40,000 tons of die forging press countries, only China, the United States, Russia and France, at the same time broke the former Soviet Union to maintain the world record of 51 years.

 

Today, China has become not only a big country of machine tool production and consumption in the world, but also the largest machine tool export country in the world. The localization of high-end machine tools has reached more than 70%, and even five-axis CNC machine tools have been successfully exported to Germany, which also marks that we will no longer be subject to other countries in the field of precision machining. But there is still a big gap between us and foreign countries in the field of machine tools, and most of the functional components are dependent on foreign countries, which is mainly related to our late start in related technology, but even so, the gap between them is little by little.
