Brothers, I have opened a new book again: Restart your life: I can call myself ten years ago, brothers, please help me collect it, and give me some recommendations!

*********************

If they were told that the Tu people still had a machine tool of a higher level than Guangyang, would these guys have to kneel on the spot?

Just talk about the iron tuotuo they saw that day who was dissatisfied with various complex cavity, the VW person was still trembling when he thought of that thing.

Although I am not a machine tool, I have been engaged in mechanical manufacturing and processing for hundreds of years.

They know too much how difficult it is to process such a complex cavity.

It can even be said that such a cavity is the most difficult workpiece in the world to process.

It is no exaggeration at all, it is harder than the turbo fan blades used on take-off aircraft aircraft aircraft engines.

Because 50% of the difficulties of turbine fan blades are materials, the remaining 30% are special machine tools, and then 20% are process.

And when they saw the cavity on the iron lump that day, they couldn't even figure it out.

Because based on their understanding of current machine tools, they can't even understand what machine tool is produced.

Anyway, Guangyang in front of him definitely won’t work.

Think about an iron ingot with a length, width and height of fifty centimeters. It is very difficult to drill a hole with a diameter of 5 centimeters on the iron ingot in a straight line and keep drilling through it.

Many people may think this is very simple, but in fact it is not simple at all.

Because you must always keep it in a straight line during the drilling process, this is the most difficult part.

There are not many machine tools in the world that can do this at present.

But the other person's machine tools can not only be easily done, but also can drill bend holes, but also S-shaped.

The most important thing is that the inner wall can be polished with mirror...

This is simply against the will of heaven.

Many people may know what such a cavity can be useful.

In fact, the use of such cavity workpieces is very great, such as various high-pressure pipelines for oil and gas transmission.

This thing used to be very delicate, especially for engines.

Because it is necessary to match the shape of the engine, the shape of these pipelines is not very regular.

Although it can be made, most people first build a straight pipe, and then use a machine to bend the straight pipe at various angles.

However, in this process, the pipe will suffer from hidden injuries, and the bent parts will be under great pressure during work and will be very easy to break.

It is a high loss component. In addition, because the bent place is unnatural, it will affect the efficiency of oil and gas transmission.

If this integrated cavity part is used, the strength will be greatly improved, not to mention life and stability.

The most important thing is that this thing is strong enough, so it can withstand greater pressure, so you can use a pump with more pressure.

This can greatly improve the performance and efficiency of the engine, especially on aircraft engines...

Moreover, this integrated molded complex curved cavity part can greatly reduce the use of traditional seals.

Because there was no such integrated cavity parts before, the factory designed various irregular shape oil pipes and gas pipes when connecting.

All fasteners must be used to butt and tighten first, and then use a rubber sleeve to seal.

However, the sealant cover will definitely age over time, and due to long-term work vibrations, the fasteners will also loosen.

Therefore, many car engines will leak oil and leak oil after use for tens of thousands of kilometers. This is a common problem for almost all German and American cars.

For Japanese cars, because they use very special sealant, it is relatively better to prevent leakage.

In the future, if such integrated and complex-shaped pipe fittings are used in large quantities, the use of seals and fasteners can be greatly reduced.

Not only can it reduce weight, but it can also greatly reduce the risk of oil leakage.

This is just the civilian field, let alone the military field.

It can even be said that with the ability to process such complex curved cavity, it can definitely be the technology in the aerospace and navigation field of Rabbit Kingdom, which is three generations higher than before.

When people think of this, VW feel sour.

Once upon a time, these rabbit people were a group of little brothers who were following behind them and they looked down upon.

But now, people can actually create such a mysterious machine.

The most important thing is that this mysterious machine tool, they don’t even know what it looks like.

Think about it, this kind of machine tool is definitely the killer level of the Tumen.

However, it seems that the Chinese people in the Rabbit have no intention to spread that kind of machine tool technology.

It may even be considered to keep the technology confidential first and not spread to the public.

The reason for this is that I am afraid of Big Brother Yingshang...

After all, poaching the wall...

Germany is the lesson of the past!

Thinking about more than a hundred years ago, their leaders couldn't help but insist on having to face Hawkshang's cousin John Bull Hard Steel.

As a result, it was hardened twice, and the final result was the world economic center, which moved from Europe to the Americas.

Instead, he made Hawk Sauce a big deal and got the best of his bags, and he suddenly became the world's boss.

And this time the rabbits are much smarter. They are going to follow the principle of quietly entering the village and not wanting to shoot!

Poaching should start quietly. By the time Hawkstone finally reacted, they had grown to the point where they could not helpless.

So the German sighed.

Since that's the case, we can only choose to cooperate.

After all, VW has to rely on the Rabbit Market to prosper.

Although their lives are not as good as before, they know.

As long as they work hard to build the car and offer a little discount on the price.

It can still win back some consumers.

After all, they have been working here for almost forty years, and the reputation they have accumulated over the years will not be consumed in a short while.

As long as electric vehicles have not fully occupied the market for one day, they will still be very nourishing.

What's more, electric cars nowadays have another well-known weakness that they cannot serve.

That is the discharge problem in winter.

Any electric car will be in winter, especially in cold zones at high latitudes.

The battery capacity will drop sharply. It would be great if you could drive 250 kilometers of mileage.

Because of this mileage anxiety, many northern consumers will not easily choose trams.

So they still have time for VW.

Although they are not in the field of hybrid and pure electric, their technology is now not ahead of the curve.

But VW people think that as long as they work hard, they should be able to catch up soon.

After all, motor technology is not a difficult task, and they don’t have much technology in battery.

But you can buy it from N De era, and there are competitions from Sansang and LG, so they are not worried about the battery.

Because of this market, no one can dominate.

What's more, even the big guy in the circle bought Tesla, so why can't VW?

Besides, BBA is not the same...

So what you have to do now is to live first...

I'm afraid I wouldn't have thought that a saying that was popular in the real estate circle of Rabbit China has now become the norm of VW...

Since I figured this out, VW people no longer struggled.

Although I understand that they are deliberately stucking their necks, so what? After all, they are facing the problem of life and death.

Surviving is the key.

If others have it, we have it too.

The current situation is that it is not impossible to use German machine tools.

But it is just about being obsessed with the brink of things, just about being indifferent to the shortcomings.

In the near future, it is destined to be killed by the auto companies in Rabbit Kingdom.

They don’t have to wait until they enter the era of electric vehicles, even the era of fuel vehicles, and they can’t survive.

According to the current development momentum of car companies such as Rabbit Country, they will have to be strong by these guys in just five years.

The reason why Rabbit Cars were not good in the past was actually because of their mechanical quality and some special technical aspects.

And now, as they continue to make breakthroughs in those technical fields, catch up, or even rush over, it will be a matter of time sooner or later.
To be continued...
