Intelligent Industrial Empire

Yun Fei did not expect that the news revealed by Li Lu was actually like this.

He really didn't expect that the North Korean side actually paid so much attention to him, the private boss of a small machine tool company from China.At least, the country has not shown too much attention to him.

Yun Fei felt a little embarrassed to think so.

For him, the state often has the green light all the way, otherwise, the large number of machine tool companies in the country will kill Jiuyi Heavy Industry.The country has always had a practice of technology sharing.

Of course, this technology sharing refers to the technology sharing of private companies to the state and those state-owned factories under the National Asset Management Committee. If the state does not attach importance to him, the CNC machine tool technology of Jiuyi Heavy Industry has been developed in his CNC machine tools. After that, they were forced to share them by large state-owned machine tool manufacturers like Northeast One Machine and Capital One Machine.

Even if he finally shut down Jiuyi Heavy Industry and burned the research materials of Jiuyi Heavy Industry, it would be of no use.

In terms of scientific research, talent is the most important.

Whether it is workers from 9327 or experts or technicians from the Soviet Union, when it comes to the choice between the state and his personal boss, he will definitely choose the country without hesitation.

What he provides, the country can provide.He can't provide what the country provides.

It's just that the country attaches great importance to Jiuyi Heavy Industry, and Yunfei does not know it now.At least, for now, it hasn't risen to the level of attention on the surface.

The world knows the arrogance of Golden Sun.That one claims to be "the most dazzling sun of the 21st century"!Otherwise, he would not be called the Golden Sun by the world.

The North Korea attaches great importance to him, which Yunfei has never thought of.

Perhaps, few people in China now understand the inevitable connection between CNC machine tools and long-range missiles.

After all, the Soviet Union and China produced strategic intercontinental missiles with a range of more than 8,000 kilometers or even tens of thousands of kilometers when they did not have CNC machine tools.For example, the Soviet Union's Topol-MD strategic missile (it is said that the range is 14,000 kilometers, or it is said to be 12,500 kilometers), China's Julang II (liquid fuel propelled, the maximum range is 8,600 kilometers), Dongfang 31A (solid fuel propelled, maximum range of 10,600 kilometers), these missiles are all handmade by ordinary machine tools.

Until the 21st century, more than ten years later, only a few people understand that the various parts on the missile processed by high-precision CNC machine tools can better guarantee the performance of the missile.

Otherwise, China's Dongfeng 41 will not achieve a breakthrough after a major breakthrough in China's CNC machine tool technology.

The breakthrough of CNC machine tool technology involves many things, not only the improvement and innovation of processing technology, but also higher requirements for materials.Only after the material is improved, the production process can be improved, and thus a breakthrough in the CNC machine tool.

The outer shell of the long-range missile does not require very high machining accuracy, but the machining accuracy of some parts inside is relatively high.For example, the flange of the fuel filler port and the inner lining of the missile shell at all levels are not very demanding if you only look at the drawings. Only when processing, the processing personnel will understand how difficult this is.

Take the lining of the shells at all levels that link the long-range missiles. This requires a machining center with at least four-axis linkage.

The domestic missile lining is not a full circle, but a full circle is processed by a lathe, and then cut into several arc parts by wire cutting according to the design requirements.Then drilled and tapped (threaded holes) on it, and finally riveted these linings with the drilled missile shell.

In the pre-processing, the processing requirements are not very high, but when the parts that are divided into several parts are drilled and tapped later, problems arise.

Many people know that a missile is basically a cone. Only in this way can it be more aerodynamic and ensure stability during flight.If the stability of the flight process cannot be ensured, even if the range of the missile produced can meet the design requirements, the accuracy range cannot be reduced to a small extent.Therefore, in China and the Soviet Union, two countries without CNC machine tools, if the accuracy range of the missile is within 100 meters of the target, it is already very accurate.

In the United States and Europe, the range of many missiles can even be guaranteed within 3-5 meters of the target.

Many people think that this is determined by the missile guidance technology.

Where do people who are not professionals know, the stability of the missile flight process also has a lot to do with it.

These things are all very professional knowledge. The reason why Yunfei knew it was because their company at the time had some business dealings with aerospace. After entering the 21st century, most of the aerospace finishing workshops, The equipment was replaced with imported CNC machine tools.

You must know that these imported CNC machine tools are worth hundreds of millions of yuan!

The addition of these equipment is only to produce a variety of missiles with a more precise strike range.

There are at least two angles on the inner lining, one is the angle along the diameter of the arc of the part, and the other is the direction perpendicular to the outer circle or the inner hole of the part (this angle is relatively small and generally does not exceed five degrees).This makes it difficult to guarantee the machining accuracy of parts for processing on conventional machine tools.

For four-axis CNC machine tools to make such parts, the requirements for the operation level of skilled workers are too high, and they are not at the master level. The scrap rate of processed parts will basically exceed 90%, even if the master does it, the scrap rate It can only be controlled at 80% to 70%.

Moreover, the processed products are barely usable.In that way, the design accuracy requirements of the missile cannot be met at all.Machining accuracy cannot be guaranteed, which will result in uneven distribution of screws or rivets at the junction of the missile shell or the place where the rocket engine is mounted on the tail of the missile. During the flight, it will be placed too much, affecting the stability of the flight process.

Only high-precision five-axis CNC machine tools can complete the processing of these parts.

Only the parts processed by high-grade CNC machine tools with five-axis linkage can guarantee the accuracy of the design.

China has always been very mysterious in the development of strategic missiles.Because foreign countries rarely know when China is conducting a missile test.

The technology of civil carrier rockets is almost the same as that of military intercontinental strategic missiles. China’s Long March series belong to civilian rockets and are designed and produced to send satellites to the sky.

If in the course of the war, with only a small amount of modification, the civilian Long March series of missiles can quickly complete the transition from civilian to military.

Only with more powerful rocket technology can the nuclear deterrence capabilities of nuclear-weapon countries be expanded to the maximum.

If one day China's land-based missiles can cover any corner of the world, then even if the United States has a navy that can cover all the seas on the earth, it will not be enough.

North Korea has been conducting secret nuclear tests, but it has never been known to the outside world.

Of course, the Soviet Union is very clear about these experiments.

With the disintegration of the Soviet Union, North Korea’s experiments fell into difficulties.

What Yun Fei does not understand is that since the establishment of diplomatic relations between China and South Korea in 1992, the relationship between China and North Korea has dropped to a freezing point. Why did North Korea take the initiative to seek assistance from China at this time, and favor a Chinese private entrepreneur like itself. There are plus.

Do they think that with CNC machine tools, their nuclear tests can make greater progress?

Or do you think that if you get your own CNC machine tools, you can get your own CNC machine technology?Then be able to develop more advanced 4-axis or even 5-axis CNC machine tools?

The relationship between the country and the country, Yun Fei did not want to understand, and did not want to understand, these things are not something a small person like him can think of.

"They really took pictures?" Yun Fei was deeply touched by the various events on the Internet.

He didn't expect that one day, he would actually become the protagonist of such a door incident.

The shamelessness of North Korean high-level officials is recognized by the entire world.

The person who does this is Jin Yi Fat or Jin Er Fat?

Jin Erpang is not dead yet!

I don't know if that guy will live a few more days because of his appearance.

"What do you think?" Li Lu smiled meaningfully at Yun Fei.

For such a thing, her heart is very tangled.

I hope that Yunfei will do this so that something happens between her and Yunfei so that she will not feel guilty; and I am very dissatisfied with Yunfei's doing this in her heart. Such a man is too unfaithful!

"..." Yun Fei was speechless.

Nima, if he were really threatened by a country with his nude photos, he would probably be as famous as the tombstones in front of many ancient tombs.

If so, should he be proud?Should we be proud?

"Does the North Korean side really think that if you get me done, you can get what they want?" As for things at the national level, Yun Fei, a Xiaobai who has never been in contact with politics, and is not ready to contact politics, really doesn't understand.

"Who knows. But I think they are mainly trying to ease relations with China. After the disintegration of the Soviet Union, the only thing North Korea can rely on is China. After the establishment of diplomatic relations between China and South Korea in 1992, the relationship between the two countries declined. At freezing point, when the capital was bidding for the Olympics last year, our country’s bid for the Olympics was unsuccessful because of North Korea’s negative vote. Kim Il Fat’s days are running out and he is preparing for his transfer of power..." Although he is not very political. Clearly, but Li Lu still knows the situation in North Korea very clearly.

These days, she is not idle.

She has her own source of intelligence.
