You, you're ......."

The head of the headquarters was amused by Zhuang Jianye's rogue energy, and pointed Zhuang Jianye with his finger, and without saying anything, he walked towards the No. 8 workbench with his hands behind his back.

Seeing that the head of the headquarters had moved, the leaders and troop leaders who had long been full of curiosity naturally followed suit, and they came to the No. 8 workbench after a while.

It is no wonder that these leaders who came to inspect did not pay attention, because the No. 8 workbench of this workshop is not as open as other workstations, but a workshop extending outside the workshop, except for two doors, there is no other important workshop outside the next door in the whole workshop.

After Liu Chun's introduction, the leaders of the troops who came together learned that they were not walking in and out of the main gate of the electrochemical perforation processing plant, but the exit of the product transfer after the processing was completed.

This makes everyone a little strange, this is to go to see and go through the front door, how to go through the back door of the shipment?

Some of the elaborate leaders' faces are a little not good-looking, but when they walk through the long corridor and see the transparent glass door not far away, what is ugly and unpleasant is not seen, because through the huge glass door, these leaders and leaders saw more than a dozen staff wearing mortal sterile clothes shuttling back and forth.

That scene, just like the large-scale research laboratory for studying microorganisms in the State Key Biological Laboratory, makes people feel full of science and technology at the same time, and can't help but wonder whether this Tengfei Aviation Power is engaged in the hole processing of turbine blades or in biomedicine.

Just when everyone was curious or puzzled looking at the busy scene inside through the transparent glass door, Liu Chun's words slowly sounded in the passage: "Ladies and gentlemen, the processing principle of our NB-711 electrochemical hole processing equipment is to use high-purity electrolyte to pass through the electrode tube made of metal titanium, and then process the air film cooling hole of the turbine blade through the injection hole with high precision.

Due to the high purity electrolyte has high requirements for the environment, our factory has set up two high-standard dust-free workshops for this purpose, which is one of them, and the other is next door, each plant has two NB-711 electrochemical hole processing equipment...... Yes...... Haha......"

Liu Chun didn't say it completely, but everyone present knew that if one or two went in, and they all went in, it would take a lot of time for the early dust and sterilization treatment, not to mention that the space of each plant is not large, only enough for two equipment and corresponding operators, if they really go in, even if they don't pollute the production space, it will also affect the staff inside.

Therefore, these leaders and leaders expressed their understanding of the choice of Tengfei Aviation Power, but understanding is understanding, and many people are a little puzzled by the practice of Tengfei Aviation Power.

You must know that the cost of a high-standard dust plant is not a small number, every brick and tile has strict standards, coupled with strict air circulation system, antibacterial dust removal system and other related supporting facilities, the cost of a plant is 10 million is ordinary.

As a result, Tengfei Aviation Power got two seats at once.

You must know that at the value of today's early 90s, more than 20 million yuan is enough to build three large-scale factories with large areas and complete supporting facilities.

If you produce biological products, high-performance semiconductors are just that, but the problem is that Tengfei Aviation Power produces turbine blades, and it is only one of the processes, is it necessary to throw money into it?

Seeing the incomprehension and confusion on the faces of many leaders and leaders, Liu Chun was not in a hurry, but smiled more brightly, and the last sentence made the puzzled and confused people instantly freeze: "The turbine blades that are precision hole processed here, whether they are low-pressure blades or high-pressure blades with higher requirements, are all one-time molding, and there is no need to do post-processing." ”

"One-time molding?"

"No post-processing?"

As soon as Liu Chun's words came out, many people had already exclaimed, because whether it was one-time molding or no follow-up treatment, it actually meant the same thing, that is, the excellent rate of air film cooling holes of turbine blades processed by NB-711 electrochemical hole processing equipment reached 100%.

Everyone was not surprised, but really shocked.

It is important to know that as an important means of realizing the cooling of the air film of turbine blades, there are many processing methods, such as mechanical processing, laser processing and EDM precision hole processing, which are respected by these leaders and leaders.

However, no matter what kind of processing, there are more or less additional effects on turbine blades, such as stress deformation and microcracks caused by machining, and thermal plating or microcracks caused by laser processing.

EDM is slightly better, only around the precision hole to produce 0.02mm to 0.01mm thick coating, put on other components, this thickness is insignificant, in the turbine blades need to withstand high temperature and high pressure of the precision existence, even lower than 0.01mm thickness of the coating may be in the turbine operation by high temperature and high pressure combined rolling deformation, rupture.

At worst, the life of the engine will be shortened, and in serious cases, it will be scrapped directly.

Because of this, the post-metallurgical treatment of the turbine blade after the processing of the air film cooling hole has become a worldwide problem, because once it is not done well, the hard-working blade is very likely to be scrapped due to micro-plating and microcracks.

In addition, the post-processing of the air film cooling holes is also related to the number of air film cooling holes, the density of the inside and outside, and these two indicators are directly related to the cooling effect of the turbine blades.

In other words, the air film cooling holes of turbine blades require not only ultra-precise machining technology, but also powerful metallurgical treatment in the later stage.

After all, from the industrialization of the fifties to the present, the domestic industrialization process is less than 30 years, while the Western countries have gone for nearly 200 years.

Because of this, the domestic catch-up in these two aspects can no longer be described as hard, and it can be summed up in despair, because you can't even see the taillights of Western developed countries, so what can you do if you don't despair?

Now, Liu Chun, the general manager of Tengfei Aviation Power, said that the air film cooling hole processed by their NB-711 electrochemical hole processing equipment is formed at one time without post-processing, so what does that mean?

"That's right, our technology has fully reached the world's advanced level, and we have achieved corner overtaking in the processing technology of domestic air film cooling holes. Before everyone could react from the shock, Liu Chun's confident words echoed in the passage again.
