Chapter 1239

I don't know how long later, the senior researcher of a mechanical research institute who was shocked by China's take-off nb-996plus Metal 3D printer finally came back to me. No wonder the head of the headquarters dared to act recklessly.

Even after the introduction of the XXX bill by a big country outside the region, China's take-off has come to this stage in metal additive manufacturing technology.

This is no longer as simple as chasing and overtaking, but a complete revolution in the traditional forging production mode.

It can be imagined that once the nb-996plus Metal 3D printer can be popularized, the traditional developed countries that rely on forging press, five axis and seven axis advanced machine tools, high-performance precision forging equipment and special welding equipment to achieve excess profits will inevitably be taken off by China, just like a hamster, one by one, and eventually suffocated in the hole.

Compared with other processes, nb-996plus Metal 3D printer is a complete dimension reduction blow.

Among other things, the production of titanium alloy spindles similar to wd-18 small turbojet engines usually requires about 500 kg of billets. After rough forging, precision forging, machining and finishing, only less than one kg of 500 kg titanium alloy is left.

The remaining 499 kg of titanium alloy is completely treated as processing waste.

You know, it's not ordinary steel and aluminum, but expensive titanium alloy. For less than a kilogram of accessories, more than 95% of the materials need to be wasted. No matter what else, the cost alone is amazing.

Using nb-996plus Metal 3D printer is not the same, the same titanium alloy spindle, nb-996plus almost no waste, because this equipment uses laser cladding technology, that is, using high-energy laser to heat titanium alloy powder, and then according to the established procedures, layer by layer the necessary accessories will be "printed" as printed words.

It can't be said that there is no waste in this process, but it will never reach the point that 499 kg of parts are needed, which is less than 1 kg. At most, one or two kg will be wasted.

In this case, the manufacturing cost of nb-996plus is greatly reduced, thus forming a cost advantage for traditional forgings.

The problem is that this is only one of the many advantages of nb-996plus Metal 3D printer. If the time cost is included, nb-996plus Metal 3D printer is simply rolling grade.

As a result, the senior researcher could not help but get excited when he wanted to understand the underlying logic of the headquarters head's insistence on implementing the operation in Belgrade.

In a word, what this senior researcher with deep experience in forging field has done is not selfish. It's just that he is different from China's take-off in technological path, so he is different in thought.

This is not to blame the senior researcher. In fact, because of the conclusion of the Americans, there are few people in the world who insist on additive technology manufacturing. After all, the United States has absolute authority in the field of technology these days. No one dares to challenge the Americans in technology, so there is no doubt.

In fact, China Tengfei did not dare to criticize the conclusion drawn by the Americans. In fact, in the early years, China Tengfei also wanted to give up additive manufacturing technology. There was no way. One conclusion of the Americans was easy to say, but it made the 3D printing equipment developed by Tengfei group at that time unsalable.

If you can't sell it or make money, you should cut it according to the concept of Tengfei group at that time.

At that time, Tengfei group was ready to do the same thing, and then applied to the higher authorities to join in the supporting introduction project of advanced forging equipment. After all, the things led by the higher authorities were guaranteed, not to mention the state's money, which could not reduce the burden on its own side.

Tengfei group's abacus is good, but the result is almost a basket of water, and nothing.

The reason is very simple. This kind of foreign procurement of complete sets of equipment project has too much oil and water, and those central enterprises are not enough to share. A department level unit of Tengfei group is like a piece of the cake? How is that possible?

So the application of Tengfei group has been shelved.

It's just that they still have a strong demand for forgings, and the whole industry is extremely immature. Just at this time, several young professors from Beihang found Tengfei group and said that they had a technical solution to realize the forging performance on metal additive equipment, hoping that Tengfei group could invest money to support them to complete the research.

At that time, Tengfei group wanted to join the national team, but it was rejected. In addition, there was a bottleneck in its own development, so it had to find a new breakthrough and profit growth point. With a try attitude, Zhuang Jianye invested 2 million yuan in the research and development of new additive equipment.

Results in the new year, the young professors of Beihang made a big titanium alloy part. After metallographic examination, the comprehensive mechanical strength was almost the same as that of the same kind of imported finished forgings.

Zhuang Jianye, who got the news, immediately realized that he had touched a big fish. Without saying a word, he immediately made an additional investment of 30 million yuan, and then gave another 80 million yuan.As a result, it exceeded the expenditure budget of Tengfei group in that year. Zhuang Jianye simply put two large forging equipment obtained from Russia's Tupolev Design Bureau on the market and raised 150 million yuan, which barely filled the hole of overspending.

Of course, not many people know about the past of selling equipment and smashing 3D printing technology, but few people don't know that Tengfei group was rejected by the national team.

At the moment, the senior researcher who was shocked by the efficiency of nb-996plus Metal 3D printer is one of the witnesses, and even the main person responsible for blocking Tengfei group out of the national team.

I can't help it. He was the senior researcher who confirmed the list of the national team. The name of Tengfei group was crossed out by him with a red pencil.

That's why even if the head of the headquarters has a backup technical solution for China's take-off, he, a senior researcher, doesn't believe it. At that time, the predecessor of this unit was excluded from the national team by him. Now you say that they have a backup technical solution, whether it's true or not, even if it's true, the senior researcher's heart can't accept it.

The bureau level enterprises you didn't look up to in the past have become the mainstay now. All the members of the national team you look up to are trampled under your feet. Where do you put the senior researchers' faces?

Because of this, the senior researcher was very excited, and it was a moment of embarrassment, because the technical leaders of other research groups surrounded Zhuang Jianye one after another, and asked him with great enthusiasm about the specific situation of nb-996plus Metal 3D printer. Some shameless people even spoke directly, hoping to buy one or two for the factories and units they once served as the main leaders Try it on the TV.

After all, the high-end manufacturing industry in China is short of forgings. Nb-996plus Metal 3D printer just makes up for this gap. Naturally, everyone wants it.

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

As a result, as soon as he said this, Zhuang Jianye said with a group of technical leaders, "in addition to the nb-996plus Metal 3D printer, we also have a nb-985plus Metal 3D printer for large structural parts. Would you like to have a look?"
