Back to the topic, the scene was silent at this time, obviously everyone was stunned by the action of the industrial robot in front of them.

Drilling holes in iron ingots is not a high technology.

But I want to drill a zigzag hole with a very complicated shape on such a square iron ingot according to my own imagination.

It's like an underground labyrinth built by moles. This is definitely not comparable to the direct shield machine drilled tunnel.

Although this workload is much smaller than that of drilling tunnels, the difficulty can be said to be increased several times, or even dozens of times.

And if this workpiece can be successfully completed, then the significance of this will be great.

On a larger scale, it can be said that it can directly raise the industrial level of country H by one level, or even two to three levels.

That said, it is not an exaggeration at all.

In today's industrial world, what kind of workpiece is the most difficult to machine?

The first is the complex curved surface workpiece that needs to be integrally formed, such as the fan blade of a turbocharger.

For example, spherical bodies of various bearings, such as balls and so on.

These seemingly inconspicuous things are very difficult to process.

And because the machine tools in our country were not good enough in the past, we have not been good at this kind of high-precision hardware processing.

Not to mention those complicated curved surface workpieces, let's talk about hydraulic oil tanks, we can't do it well.

Many people may complain when they see this. You are talking nonsense. After all, we are the world's largest industrial country. How can we not even make hydraulic oil tanks well.

But the reality is like this, in the field of hydraulics, we really can't do it.

Especially the hydraulic systems used on those large construction machinery are actually imported from Japan, and their machines are actually assembly machines.

So why is there such a problem?

This involves the processing and sealing of the hydraulic oil tank, because hydraulic equipment often requires some control valve bodies.

And this valve body is to control the oil pressure, increase the hydraulic pressure, or reduce the hydraulic pressure, all rely on this valve body to complete the work.

And the processing of this valve body is the most difficult to manufacture in the whole set of hydraulic equipment.

The most typical example is the hydraulic torque converter used in the AT gearbox of a car.

This thing used to be an iron box, but now in order to reduce the weight of the body, Aisin and ZF have replaced it with an aluminum alloy valve body.

The aluminum alloy smelting of this valve body has a very high technical content.

But this, we can do now.

However, the aluminum alloy has been solved, but it is very difficult to turn and mill the aluminum alloy ingot to make a hydraulic oil tank.

If you have seen this hydraulic torque converter, you will know that it is actually a box composed of two almost identical boxes buckled together.

And when you split it from the middle, you can see that there are very complicated oil circuits on both sides of the box.

These oil passages are winding, and the shape is as complicated as a maze in a video game.

Moreover, the pipe wall of the oil circuit must be uniform in thickness and smooth in surface, which places very high requirements on the machine tools used for processing.

Because you have to move a knife on an aluminum ingot to carve such a complicated box.

This is not the most difficult part, the most difficult thing is, do you want to carve another half of the box that is almost exactly the same as this one on another aluminum ingot?

Don't think this is very simple, because you have to control the error within a few wires.

Because if the error is too large, then when the two boxes are closed, there will be even a slight error in the hydraulic pipe, then when the hydraulic oil is working inside.

As long as the oil pressure is increased, the gap created by this slight error will expand, and then oil will leak outward.

In this way, according to the design, the transmission efficiency of your hydraulic torque converter was originally designed to be 95%, but it would be good if it could actually reach 80%.

In this way, even if the engine power of the car is strong, the efficiency of the actual transmission to the tires on the wheels is not high.

In this way, it will appear that the false standard of the engine data is too high, and the driver does not get a good power experience, but the car still consumes a lot of fuel.

Then this transmission is equivalent to a waste...

This is the problem we often encounter in the hydraulic torque converter of our self-produced transmission, and we have never been able to provide customer service.

Because this involves several issues of machining accuracy, and we simply cannot get the kind of high-precision machine tools used by Japanese and German automobile manufacturers.

This is also one of the main reasons why we have not been able to overcome the AT hydraulic automatic transmission.

It can even be said that it is one of the main reasons why we are still unable to make breakthroughs in the field of hydraulic pressure.

As for the sealing, we are even further behind. The seemingly ordinary sealing rubber rings we produce will be finished in three months.

As for the ones produced in Japan and Germany, after a few years of use, the car can run more than 100,000 to 200,000 kilometers without any problems, and there are more ways to do it.

Machining accuracy, sealing, these are obstacles that hinder us from making breakthroughs in this field.

On a larger scale, in terms of turbine blades, this is even more of a headache for us.

Why have we been unable to make breakthroughs in the field of aircraft engines?

The material is one reason, and another aspect is high-precision machining, which is also a big problem.

Just like the combustion chamber of an aircraft engine, this is a metal cavity with a very complex curved surface.

The F119-PW-100 afterburning turbofan engine used on the old American F22 fighter jet is the king of this field.

This kind of engine also has a very complicated rotor inside the combustion chamber, and this rotor is actually a long shaft covered with blades of various turbofans.

Just looking at those blades is already a headache, and what makes you more headache is that you don't know how these blades are processed and installed on that rotor.

Mao Xiong also has a similar engine, but Mao Xiong's method is much simpler and rude.

They directly built a hyperbaric chamber, and then let workers wear pressure suits to complete welding under several times, or even ten times the atmospheric pressure.

The turbofan blades, which are hard and not suitable for deformation, are welded to the rotor forcibly.

As for the United States, it is even more amazing, they can actually form one body.

Welding technology is not used for reprocessing, but a mode of ionic single crystal growth is used.

Let the turbofan blades grow to the rotor, and grow according to their design shape, this is the strength of Laomei.

As early as ten years ago, let alone production, we didn't even know how the blades of other turbofans were produced.

It wasn't until the last ten years that we figured it out.

Oh, it turns out that the turbofan blades of others can work in such a high-intensity working environment without deformation or falling off.

It's because people added metal rhenium to the blades!

It turns out that their single crystal blades are special alloys composed of titanium and rhenium.

No wonder, their turbofan blades are hard enough, can work in a high temperature environment exceeding 3,000 degrees, and have super creep resistance...

In order to figure out the blade material, we sacrificed countless 'employees' in the United States.

Then we began to recruit this metal rhenium all over the world, but at this time we discovered that the rhenium resources in the world are almost not monopolized by the United States and Russia.

Needless to say, Mao Xiong has a big family and a big business, and there are almost no resources that are lacking in his country.

The United States controls almost all rhenium resources in other parts of the world.

Even if we want to buy at a high price, we can't buy it.

In addition to these two, in the French colonies in Africa, there is still a little bit of rhenium mine.

This situation was not alleviated until in recent years, after we discovered a rhenium mine in a certain mountainous area in China.

That is to say, since then, our WS-15 and WS-20 engines have been brought up for discussion, and there has been talk of localization.

You must know that before, we have always imported engines from Mao Xiong.

But even the WS-15 and WS-2 have serious shortcomings.

That is the lifespan. Compared with the engines in the United States, it is really far behind.

After solving the material problem, the next thing that bothers us is the processing problem of Hangfa.

Although we got some high-precision five-axis CNC machine tools through a neutral country in Western Europe.

However, how to process aviation hair is still a difficult problem.

This situation was not resolved until we recruited many aviation experts from Ukraine.

Only then did we know that the turbofan blades on Maoxiong Hangfa's rotor were actually welded in the hyperbaric chamber.

Moreover, during welding, the chamber must not only be under high pressure, but also at an extremely low temperature, so as to ensure certain properties of the metal.

Then we carried out some extensions and innovations based on Mao Xiong's approach, which led to the birth of Turbofan-15 and 20.

But to be honest, the reliability and lifespan are almost the same as Mao Xiong's, but it is still far behind the American Aircraft.

Especially in terms of reliability and lifespan, it is really too bad.

It is because there is no one-piece technology like others.

Let’s not talk about the technology of using monocrystalline silicon wafer growth technology on the drill to make turbofan blades.

As for the curved surface processing of other people's combustion chambers, we can't compare with this.

You must know that our combustion chamber is still welded, but others have already formed it in one piece.

Do you say it is comparable in terms of compression resistance, durability, and reliability?

But now, when everyone sees this industrial robot of Xinghuo Technology, drilling and digging holes inside the iron ingot.

After the previously seemingly complicated hydraulic oil tank was directly molded into one piece.

Many people can't help themselves.

Especially a person standing in the crowd, this is also an entrepreneur, his name is Yang Lei! ,

And the project that he has passed the review of this venture is a new type of fiber material.

This material, because of its molecular shape, is a hexagonal honeycomb structure.

Therefore, this material has very good characteristics in terms of flame retardancy and high temperature resistance.

It will be used in a wide range of fields in the future, such as fireproof materials and aerospace, and the prospects are very broad.

Therefore, his project received investment from Quanye Fund, and he was also invited to visit Xinghuo Factory.

But now seeing the performance of the industrial robot in front of him, his other identity, Special Service of the Equipment Department, was activated immediately!
