My Strength Does Not Allow Me to Low-key

Opened a new book: The End of the World: My House Can Be Upgraded, Brothers Help Collect, Give Some Recommendations!

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

If you talk about leveling the technology gap with Europe and the United States, this is actually a leap forward to catch up.

If you are surpassing them by ten or eight years, it is a bit unreasonable.

People will definitely suspect you of cheating.

If Yingjiang really realizes that they have no technical advantage on our side, they will turn upside down immediately if they don't guarantee it.

After all, as the vanguard of the Western world, they certainly cannot accept being surpassed by Eastern civilization.

After so many years, Lu Yuan still knows the urinating nature of the people over there.

So now it is necessary to complete the transcendence quietly so that they will not be alerted in advance.

In this regard, the first breakthrough we made was the honing machine.

If you really want to talk about this thing, many people may not quite understand what this machine is for.

To put it bluntly, it is drilling.

He can drill holes for iron rods as small as one millimeter in diameter, tens of centimeters in diameter, or even one meter in diameter.

And this process sounds simple, but there are not many companies in the world that can truly achieve the ultimate.

If you really want to achieve the ultimate, it really has to be a German company, such as Green, or an old company like Nagel that has been deeply involved in this field for dozens of years.

Especially Germany's Green, who is one of the best.

The 120mm tank gun used on the world-famous German Leopard II tank was drilled with their machine tools.

This process sounds very simple, but if you really want to do it, it is really rare and couldn't be more difficult.

Not to mention the difficult work of drilling tank barrels.

Let's talk about honing the inside of the cylinder block of the engine, which is not a job that ordinary machine tools can do.

In order to ensure the best air tightness, when honing the cylinder of the engine, the precision requirements are very high.

Ordinary machine tools can't do this kind of work at all.

Therefore, many automobile manufacturers purchase Green's honing machines in large quantities.

Moreover, such a machine tool can not only polish and polish the inside of the cylinder block of the engine, but also punch holes in the engine.

For example, crankshaft holes, balance shaft holes, etc., these requirements for precision are also very high.

Ordinary machine tools are simply not capable of such work, so we all purchase a large number of German machine tools for this kind of processing.

Because this kind of processing has several major problems.

The first is the hardness of the tool, which involves the metallurgy of the material.

Are we relatively weak in this respect? Even in recent years, we have made breakthroughs in some special alloy steels.

But if we really want to produce cutting tools suitable for machine tool processing, we are really far behind in this respect.

Because the requirements of this machine tool are far more than those of special alloy steel.

You are like the drill bit of this kind of honing machine, which is required to drill holes in extremely hard special alloys.

Therefore, it is required to be extra hard and wear-resistant, and because of metal friction, the drill will definitely heat up at high temperature.

And in this process, you have to ensure that it will not be deformed, which will greatly increase the difficulty of drill bit production.

It can be said that this aspect has always been one of our shortcomings, which cannot be further shortened.

At present, in my country's machine tool industry circle, almost all the cutter heads used by machine tool factories are imported.

And most of them are imported from Germany and Japan.

And like machine tools, Japanese ones are more cost-effective, while German ones are expensive, but you get what you pay for.

In addition, it is a question of positioning. For example, why is your German honing machine so good?

It is because of the precision control in the process of drilling the round iron rod, which can really be said to be extremely wonderful.

This drilling process, we will find it very simple when we watch the video.

But in fact, the knowledge here is too big.

For example, when the drill bit is drilling an iron rod, if the drill bit goes down, how do you ensure the positioning of the drill bit?

After all, the drill bit is mechanically controlled, not human-controlled.

What if the drill bit deviates during the drilling process?

This involves the positioning of the drill bit, because the iron rod is extremely hard. When you drill, friction and heat will definitely occur, which will cause the iron rod to deform.

So even a deformation of one micron or two microns will cause the drill bit to yaw.

Once the yaw, the drilled hole is crooked, and the workpiece is a waste product.

In this regard, the Germans have indeed achieved the ultimate.

It can even be said that this is their unique skill, anyway, it doesn't matter how you heat up during the drilling process, and how your material rod deforms.

Other people's drills can drill straight through, which can ensure that the hole is drilled straight for you, and the error is the smallest.

This is also the main reason why Eagle Sauce has to purchase a large number of their honing machines to process pipe tools for themselves.

In the past, we tried every means and wanted to buy several such machine tools from the Germans.

Unfortunately, the Germans have been stuck to death.

If you want to talk about civilian-grade machine tools, they can sell them to you.

But you want to say that you want industrial-grade honing machines, especially honing machines used to produce aircraft cannons and special workpieces on warships.

hehe…

So we can only find a way from other aspects.

For example, we made good friends with some Eastern European countries in Europe, and then got some honing machines through them.

Although it is second-hand, it is enough for us to ship it back.

It is through some "technical" means that we have obtained enough machine tools to ensure our military strength.

You are like our tank guns, which are no weaker than Western ones in terms of strength.

But if you want to talk about our diesel engine, then it won't work.

Especially now that many countries have miniaturized gas turbines and installed them on tanks.

For example, Maoxiong and Yingjiang, their new generation of main battle tanks use gas turbines.

Needless to say the benefits of this kind of engine, the performance can only be described as burst.

The addition is fast, and the speed is increased rapidly. In just a few seconds, the speed of more than 50 tons of iron bumps can be increased from zero to more than 100 kilometers per hour.

And it can also make the tank gallop for several hours at a speed of more than one hundred kilometers.

Anyway, the advantage is that it is much more powerful than traditional diesel engines.

But when it comes to our tanks, diesel engines are still used until now.

Because we have always been weak in gas turbines.

Not to mention the miniaturization used on tanks, even the large ones used on ships, we can't do it!

In this field, it can be said that Mann of Germany and Caterpillar of Eagle Sauce have always been the specialty.

And the processing of this gas turbine, on the one hand, is the blade with complex curved surface, our processing ability is not enough.

There is another aspect, which is the integrated compressor part of the gas turbine and the combustion chamber, which we have been struggling with!

You just talk about the compressor, the principle is very simple, and it can even be said that everyone knows it.

It is to suck in a large amount of air and compress it.

After compression, it is used to blow the blades on the rotor to drive the rotor and drive the rotor to rotate.

Then pressurize the air, send it into the combustion chamber, and eject the exhaust gas after combustion to form a reaction force.

The reason is very simple!

But the problem is that we can't produce a one-piece compressor cavity!

In fact, this kind of compressor can also be welded, but it is better to use welding in the civilian field.

If you use it on a military gas turbine, this thing has its own inherent deficiencies.

Because you have to ensure that the compressor works in a high-temperature and high-pressure environment for a long time, and sometimes the temperature of the air in contact with it is as high as 2300 degrees.

The atmospheric pressure in the cavity even exceeds one hundred atmospheres...

With such high temperature and high intensity, you have to work continuously for several hours.

Ordinary welding chambers have long been unable to withstand the huge pressure and broke apart.

And if your cavity is directly integrally formed, that is to say, use a honing machine to drill holes inside and then grind it out.

Then the strength must be enough, unlike the welded cavity.

Maybe once or twice, it can still hold up, and ten times or eight times can still be used.

But once the use time exceeds one hundred hours, metal fatigue will appear in the welding point, and then problems such as trachoma and cracks will appear.

As a result, the life of the compressor is greatly shortened.

The same combustion chamber also faces the same problems and working conditions, and the working conditions faced by the combustion chamber are even worse.

After all, the high-temperature and high-pressure gas and aviation fuel must be fused and burned here, and then sprayed out.

Therefore, it has to withstand the test of high temperature and high pressure for a long time.

If it is a welded combustion chamber, it is naturally impossible to ensure a high-intensity working condition for a long time.

But if it is manufactured in one piece, the strength and lifespan are several times, or even dozens of times, that of the welded workpiece.

Therefore, honing machines are the top priority in the eyes of high-level domestic industry leaders.

Because this thing can be used in all aspects of aerospace, national defense technology improvement, and civilian industrial technology improvement.

Therefore, the honing machine is the most ordered for Xinghuo Technology.

It can be said that this kind of machine tool is a breakthrough that we are very close to.

With the right honing machine, we can achieve multi-point blasting in many fields.

After all, in many fields, what we are actually missing is the last shiver.

And Xinghuo Technology did not disappoint everyone.

The honing machine is small enough to cover an area of ​​1.6 square meters and can drill 8-45mm, and as large as 30 meters long, covering an area of ​​150 square meters, and can drill large workpieces from 50mm to 300mm.

On the side of Xinghuo Technology, it only took more than a month to get it out.

After all, with that flexible processing machine tool, many of the original problems were solved.

In addition, this Xinghuo factory has never done any work on materials. Many special metal blades that we could not produce before are all small cases here.

So in less than a month, more than 20 large and small honing machines were produced.

Then the companies that placed the orders were called to check and accept...
