In recent years, China’s defense industry has undergone earth-shaking changes, rapid development in technology and technology, and has also been freed from financial constraints. Not only that, but also achieved remarkable achievements – China has established a defense industry system that can independently develop high-tech weapons platforms, and has basically achieved self-sufficiency. Among them, advanced stealth fighters (歼-20, 歼-31), aircraft carriers (002 domestic aircraft carriers under construction, third, fourth…), stealth drones (Pterosaur-2, etc.) and new Cutting-edge weapons such as a…

According to the China Nuclear Group news, after eight years of technical research, China has finally broken the long-term monopoly of foreign countries and broke through the core technology of nuclear grade zirconium (N36 zirconium alloy) preparation! This breakthrough means that China has successfully mastered the complete N36 zirconium alloy engineering preparation technology with independent intellectual property rights. So, what is the N36 zirconium alloy material used for? Is it important? Of course, it is important! Perhaps you also know…

In 2018, this is an unusual year. In this year, let’s not say anything else. In terms of navigation satellites, China has completed ten Beidou satellite launch missions! Moreover, not only did the intensive launch mission of the “Ten to Beidou” be completed, but the scientific and technological workers in China shortened the total process time by nearly 1/3 by optimizing the process. Of course, this unprecedented speed has a reason. According to experts, these three reasons ensure the speed…

According to the Chinese Academy of Sciences plasma news, China’s magnetically constrained nuclear fusion experimental device “artificial sun” has made a major breakthrough, laying an important technical foundation for the subsequent development and utilization of nuclear fusion clean energy. You may not be very familiar with nuclear energy. You are not very clear about what this breakthrough means. Next, let’s take a closer look at the knowledge of nuclear energy, fission energy and fusion energy, in order to better understand…

It is reported that the first China International Import Expo opened in Shanghai, China National Convention and Exhibition Center (Shanghai). Among them, the largest exhibit of the “volume” at this fair is a high-precision machine tool with a total weight of about 200 tons – Jinniu Longmen Milling Machine. It comes from one of the world’s largest manufacturers of high-precision heavy-duty machine tools, Germany’s WALDRICH-COBO Machine Tool Manufacturing Co., Ltd. The high-precision machine tool manufacturing company was founded in 1920…

From rocket engines to all kinds of maritime hair, have countries been smashed “card necks”? This is a big proposition and a small proposition. First of all, let’s talk about the Long March. As we all know, the Long March 9 carrier rocket is a new generation of heavy rockets being developed in China. It is a “sci-fi level” and will be used for deep space exploration, manned moon landing and fire, space infrastructure construction, etc. First flight between 2028…

The near-anti-aircraft is a short-range defensive weapon. It is mainly used to intercept anti-ship missiles and rockets, missiles or aircraft that attack our ships. It can also shoot at sea targets. It is the last barrier of military defense. Therefore, it is necessary to kill and completely destroy the weapons and equipment. Otherwise, they will still cause damage to our army by virtue of superior inertia and kinetic energy. Based on this situation, it is necessary to use the most…

In recent years, the accuracy requirements of machine tools for machine tool processing have been continuously improved with the continuous development of China’s manufacturing industry. Among them, the precision requirements of wire cutting machine tools are the most urgent. In the online cutting industry, the mainstream “medium wire” is widely used in the fields of mold making, precision small parts, special materials, cams, forming tools and sample processing, because this machine is used to process certain parts. This not only…
