Chapter 613 NB-233 Laser Additive Equipment

Previous page        Return to Catalog        Next page

    Wang Huan and others are no longer calm now. They have seen welding, casting, and machining. This is the first time they have seen components growing on their own.

    Wang Huan almost thought there was something wrong with his eyes. He took off his glasses and rubbed his eyes vigorously without saying anything. He took out his handkerchief and wiped the glasses over and over again. Then he put them back on and stared at the screen. Only then did he realize that they were not his own.  There is something wrong with my eyes, but the parts in the workbench are growing on their own. Although it is slow, the growth is not slow.

    "Thisthisthis"

    For a moment, Wang Huan pointed at the screen. He had not seen anything like this for a long time. He had no choice but to do it. The situation in front of him was so weird that Wang Huan didn't know what words to use to describe it.

    "This is the key to our repair of the JT9D turbofan engine. The nb-233 integrated manufacturing equipment that applies new laser additive manufacturing technology can directly process some special parts within fifteen centimeters in a full vacuum environment."

    At this time, Qiao Shiming suddenly spoke, with undisguised appreciation on his face, as if he was looking at his outstanding child, full of pride: "The reason why we were able to complete the repair of the damaged crown of the low-pressure turbine blades in three days is because we used  This is the device.¡±

    "Laser additive manufacturing technology? Can special parts be directly processed?"

    After listening to Qiao Shiming¡¯s words, Wang Huan seemed to have grasped something, but he seemed to have grasped nothing. The problem was that Qiao Shiming¡¯s words were too general, and Wang Huan did not understand them at all.

    Fortunately, Zheng Yongning came into play at this time and began to do some simple science popularization.

    It turns out that this nb-233 is a special production equipment jointly developed by the North China Laser Research Institute and the National Defense Technology University in Central China.

    The initial idea of ??both parties was to expand the scope of application of the laser welding machine developed by Tengfei Laser Research Institute and develop a high-power precision laser welding equipment for the aerospace and shipbuilding sectors.

    Used for precision welding of space launch vehicles and special welding of submarine hulls.

    Such an important subject inevitably requires a lot of testing. As a result, after a welding test on high-temperature resistant alloys in a vacuum environment, it was found that the welding wire of the same material can not only firmly stabilize the two components, but can also be superimposed in other directions of the components.

    This discovery opened a window, and several experts involved in the development suddenly discovered that there seemed to be more options besides laser welding.

    Later, with the deepening of research and the collection of data, experts realized that the United States had already begun research in this area as early as the 1970s, and called this laser additive manufacturing technology, which is mainly used for small, high-temperature resistant aero engines.  Integrated molding of components.

    Having made a discovery and found the source, the two development units immediately formed a memorandum to report to the superiors.

    The aerospace department has to say that it attaches great importance to this, but because there is too little information on this type of information and it is a new discovery, it does not know what the application prospects are. In addition, its focus is on laser welding machines, so it only provides simple support for this new discovery.  It is not included in the focus of assistance.

    But it was different at Ascendas Group. Zhuang Jianye took a breath of cold air after seeing the memo. Laser additive manufacturing technology, the name is difficult to pronounce and complicated, but Zhuang Jianye knew that this thing would have another market more than ten years later.  The name of the wind, industrial 3D printing technology.

    Especially with the development of computers and industrial design software becoming more and more refined, with this kind of industrial 3D printing technology, those complex components that previously required multi-axis machine tools and high technology can be finalized with the design software on the computer.  It can be produced on high-level industrial 3D printing equipment.

    No need for drawings or heat treatment, just simple grinding and polishing, it is a perfect usable component, completely subverting the existing manufacturing industry pattern.

    It would be unreasonable not to support this.

    Ever since, Zhuang Jianye spent a lot of money and added an additional R&D budget of 50 million, and also allocated a project bonus of 4 million to the entire R&D team.

    The technical staff of Tengfei Laser Research Institute have long been accustomed to the generosity of their boss. Although they are happy to see the funds and bonuses, they are not excited.

    The technical staff of a certain university in central China are different. It¡¯s okay to spend so much money, and there is also a bonus of more than 4 million. It¡¯s just a preliminary discovery, so there are so many bonuses?  These ivory tower technicians are going crazy.

    They couldn¡¯t believe it until the money fell into their hands. They thought they were dreaming, because many people had never seen so much money in their lives.

    This has caused many people who were preparing to complete this project to go abroad to change their minds and feel that there is not hope in the country.There are few conscientious companies like Ascendas Group that respect science and value scientific research.

    So the enthusiasm of the technical staff in these universities was fully aroused, and they all focused on laser additive manufacturing technology.

    Tengfei Laser Research Institute took a look and wondered where this would work?  They started out by doing lasers. If they are compared to others, where will they put their faces in the future?  So I tried my best to use laser additives.

    ????????????????????????????????????????????????????????????????????????????????????????????????????????????????????????????????????????????????????????????? By a kind of competition between the two sides, while at the overall level they are cooperating with each other, and with the investment of real money, the two sides have made rapid progress.

    The trial production of the first-generation prototype was quickly completed.

    The leaders of the aerospace department who were still confused about laser additive technology were able to produce a fixed support frame for a certain type of launch vehicle in one day after viewing the first-generation prototype, and the performance level was higher than that of similar products produced traditionally in the past.  After being completely consistent in performance.

    The previous dissatisfaction with the two teams for slowing down the progress of laser welding development disappeared immediately. You must know that although the support frame of this type of launch vehicle is not large, the design specifications are extremely high, and it is also a special shape. It is difficult to mass-produce and can only be produced in small batches.  With separate production and a series of complex follow-up processes, the general production cycle is more than one month.

    But now with laser additive manufacturing technology, one can be produced in just one day.

    This efficiency may be maddeningly slow in other industries, but in sophisticated and complex industrial categories such as the aerospace field, being able to produce complex and key components in one day is a super-class miraculous existence.

    So after understanding the details, the leaders of the aerospace department immediately went to the capital to report in person, and soon included this key cutting-edge manufacturing technology into a key national support project. The aerospace department was responsible for the leadership, and the Ascendas Group assisted and guided the two major companies.  The team specifically undertakes specific research and development tasks.

    In this way, laser material forming technology officially entered the fast lane, and soon developed a second-generation product, which was named nb-233 by Zhuang Jianye himself.

    This machine in the Tengfei Aviation Repair Shop is the first nb-233 equipped in the Tengfei Group. It is mainly used for the integrated molding of small special-shaped aircraft parts, thereby improving the efficiency of aircraft maintenance.
