Chapter 1239 NB-985Plus specializes in large structural parts

Previous page        Return to Catalog        Next page

    I don¡¯t know how long it took, but the senior researcher at a certain mechanical research institute who was shocked by China¡¯s Tengfei nb-996plus metal 3D printer finally came to his senses. No wonder the head of the headquarters dared to act in Belgrade regardless of the fact.

    Even after a large country outside the region introduced the xxx bill, it still felt confident. It turns out that China Tengfei has already reached this step in metal additive manufacturing technology.

    This is no longer as simple as catching up and overtaking in corners, but a complete revolution in the traditional forging production method.

    It is conceivable that once the nb-996plus metal 3D printer becomes popular, the traditional developed countries that rely on forging presses, five-axis and seven-axis advanced machine tools, high-performance precision forging equipment and special welding equipment to achieve excess profits will inevitably be replaced by China.  Teng Fei was like beating a mole, each one was beaten to a bloody head, and eventually they were suffocated in the hole.

    There is no way nb-996plus metal 3D printer is completely dimensionally reduced compared to other processes.

    Not to mention anything else, the production of a titanium alloy spindle similar to the wd-18 small turbojet engine usually requires about 500 kilograms of blanks. After rough forging, precision forging, machining, and finishing, the 500 kilograms of titanium alloy is finally  There is less than a kilogram left.

    The remaining 499 kilograms of titanium alloy are completely treated as processing waste.

    You must know that it is not ordinary steel and aluminum, but expensive titanium alloy. For accessories of less than one kilogram, more than 95% of the material needs to be wasted. Regardless of other things, the cost alone is staggering.

    Using the nb-996plus metal 3D printer is different. With the same titanium alloy spindle, the nb-996plus produces almost no waste because this equipment uses laser cladding technology, which uses high-energy lasers to heat titanium alloy metal powder, and then follows  The established program "prints" the required accessories layer by layer just like printing text.

    It cannot be said that there is no waste in this process, but it will never reach the point where components that require less than one kilogram consume 499 kilograms. At most, one or two kilograms are wasted.

    This is almost negligible for the high value-added aerospace field. Under such circumstances, the manufacturing cost of nb-996plus is greatly reduced, thus forming an unreasonable cost advantage over traditional forgings.

    The problem is that this is only one of the many advantages of the nb-996plus metal 3D printer. If the time cost is also included, the nb-996plus metal 3D printer is simply a crushing level of existence.

    So after the senior researcher figured out the underlying logic of the head of the headquarters insisting on carrying out the Belgrade operation, he couldn't help but get excited.

    After all, this senior researcher with extensive experience in the forging field has no selfish motives in what he does. It is just that the technical path is different from that of China Takeoff, so there are differences in thinking.

    This cannot be blamed on this senior researcher. In fact, because of the American conclusion, there are not many people in the world who insist on additive technology manufacturing. After all, the United States is the absolute authority in the technical field these days, and no one dares to do so in technology.  Those who challenged the Americans naturally had no questions.

    In fact, China Ascendas did not have the guts to criticize the conclusions that the Americans had worked so hard to reach. In fact, in the early years, it also wanted to give up additive manufacturing technology. There was no way. The Americans came to a conclusion that was easy to say, but it made Ascendas Group devote great efforts to development at that time.  3D printing equipment is directly unsalable.

    If it can¡¯t be sold and it can¡¯t make money, it should be axed according to the philosophy of Ascendas Group at the time.

    At that time, Ascendas Group was also planning to do this, and then applied to its superiors to join the supporting introduction project of advanced forging equipment. After all, things led by superiors were guaranteed no matter what, not to mention that the state would pay for it, so it would not be possible for itself.  Can reduce burden.

    Ascendas Group¡¯s calculation was good, but the result was that it almost failed to draw water from a bamboo basket and ended up in vain.

    The reason is very simple. This kind of external procurement of complete equipment projects is so huge that even the centrally managed enterprises cannot get enough of it. Is it like a department-level unit of Ascendas Group to get a share of the pie?  How can it be!

    So Ascendas Group¡¯s application was shelved.

    Seeing that it was not possible to join, it was just that I still had a strong demand for forgings, and the entire industry was extremely immature. At this time, several young professors from Beihang University approached Ascendas Group and said that they had a method that could be used in metal forgings.  It is hoped that Tengfei Group can invest money to help them complete this research.

    At that time, Ascendas Group wanted to join the national team but was turned away. In addition, its own development had encountered bottlenecks. It had to find new breakthroughs and profit growth points. So with the attitude of giving it a try, Zhuang Jianye invested 2 million for  The development of new additive equipment.

    As a result, when the New Year came around, those young Beijing studentsProfessor ?? then made a palm-sized titanium alloy component. After metallographic examination, the comprehensive mechanical strength was almost the same as that of similar imported precision-machined forgings.

    After receiving the news, Zhuang Jianye immediately realized that he had caught a big fish, and without saying a word, he immediately invested an additional 30 million, and then gave another 80 million.

    As a result, the Ascendas Group¡¯s expenditure budget for the year was exceeded. Zhuang Jianye simply put two large forging equipment obtained from Russia¡¯s Tupolev Design Bureau on the market and raised 150 million, which barely made up for the overspending hole.

    Of course, not many people know about the past of selling equipment and investing in 3D printing technology, but few people don¡¯t know that Ascendas Group was rejected by the national team.

    At this moment, the senior researcher who was shocked by the performance of the nb-996plus metal 3D printer was one of the people who witnessed it. He was even the main person responsible for blocking Ascendas Group from the national team.

    No way, he was the senior researcher who determined the roster of the national team back then, and it was he who crossed out the name of Ascendas Group with a red pencil.

    This is why the head of the headquarters, a senior researcher, does not believe even if China Tengfei has backup technical solutions. The predecessor of this unit was excluded from the national team by him back then. Now you say they have backup solutions.  The technical solution, let alone whether it is true, even if it is true, the senior researcher cannot accept it in his heart.

    "The department-level enterprise that you looked down on back then has now become the mainstay, trampling all the national team members you were interested in. Where do you want the senior researcher to put his face?"

    Because of this, not long after the senior researcher was excited, he felt embarrassed because the technical leaders of other research groups surrounded Zhuang Jianye and asked Zhuang Jianye with great enthusiasm about the specific situation of the nb-996plus metal 3D printer. Some  The shameless ones even asked directly, hoping to buy one or two units to try out for factories and units where they once served as major leaders.

    After all, the country¡¯s high-end manufacturing industry is in short supply of forgings. The nb-996plus metal 3D printer just fills this gap, and naturally everyone wants it.

    The problem is that other people can speak, but senior researchers have no face to open their mouths. They can only complain in their hearts. They can only make small products. Large products have to be imported. What's the use?

    As soon as he said these words, Zhuang Jianye over there followed the technical leaders and said cheerfully: "In addition to the nb-996plus metal 3D printer, we also have an nb-985plus metal 3D printer that specializes in large structural parts. Everyone  Do you want to take a look?"
