Intelligent Industrial Empire

"Damn, don't mention it, if you can get together, what are you doing? The vampires in West Germany know that we urgently need a four-axis machining center. The price is 1.96 million US dollars. Now that the negotiation has reached a deadlock, Lao Zhao was so angry that he jumped and scolded people all day..." Ren Zhiguo didn't want to care about Yun Fei's not raising the price because of this.

"Not so? Do they really want to make money?" Yun Fei asked Ren Zhiguo in surprise.

It turned out that in his world, Dirk in West Germany was the first to sell a four-axis machining center to China.Yun Fei knew this very well, because the master who taught him the programming of the CNC machining center at that time was the first person in the aerospace system who came into contact with the four-axis machining center.

For the CNC machine tools of STÜKEN, in the mouth of Master Yunfei, it can be called a magical tool.

In 1990, shortly before the reunification of the GDR and the Federal Republic of Germany, China succeeded in collaborating with West Germany, the best manufacturer of CNC machining centers in Federal Germany, and purchased a batch of four at a price of $1.7 million. CNC machine tools with axis linkage.The exact number is unknown to Yun Fei's master. Anyone who understands knows that there will never be a lot of this number.As for his master's factory, it was because the factory at that time was mainly for military production, and the world's production was of top technology.

Many people in later generations knew that the international situation that China was facing was very complicated. For the sake of national defense and security, the third-line construction began shortly after the founding of the country.Moved the few high-precision and cutting-edge technology factories and weapons production factories in mainland China to the Bashu Basin.

Especially the most important production of missiles, especially the production of intercontinental missiles, is located in the depths of Daba Mountain.Like China's solid-fuel strategic missile Dongfeng-31, liquid-fuel missile Julang-2 and some other models, most of the assembly plants are built inside the hollowed out Daba Mountain.

It is said that it is only said that a large part of the carriers of China's Underground Great Wall project are provided by factories deep in Daba Mountain.However, Yun Fei heard this legend and searched the Internet for several months, but did not get any information that could prove the authenticity of this legend.

Bashu has high mountains and many mountains, and is backed by the world's highest Himalayas, which is the last of China.It was very difficult for the imperialists to use airplanes or warships to blow up deep in the mountains of Bashu, which is far away from the sea.Therefore, at that time, China's most sophisticated equipment, as well as the most sophisticated weapon manufacturing, were located in the depths of the Daba Mountain behind the entire Chinese rear.

At that time, Western countries only slightly relaxed their controls on three-axis machining centers in mainland China. For strategic high-end CNC machine tools with more than four axes, China should not expect it.Yun Fei heard from his master that at the time, China actually hoped to be able to purchase five-axis linkage CNC machine tools and sway around the world.It just happened to encounter an undercurrent surging, splitting Germany that was about to reunify for forty-five years.

It is said that it is also said that at that time West Germany sold it to China's four-axis machining center because of domestic funding problems.They also wanted to sell the five-axis machining center. Unfortunately, the Toshiba incident in Japan did not take long. Although the Batumi embargo committee has been disbanded, there are still the United States, the world police, and the various member states of the North Atlantic Treaty Organization. These are strategic military production equipment.

In the end, I don’t know how to transport it back. Anyway, there is no spread in the world that the German Dirk company sold a four-axis machining center to China in the early 1990s.After the successful transaction, China also wants to continue to purchase more four-axis machining centers. With the disintegration of the Soviet Union, the unification of Germany, and the end of the Cold War, those countries that did not engage in the Cold War with Lao Maozi have more time and energy to watch. Their allies are privately dealing with the red camp.

The master Yunfei who taught him the programming of CNC machining centers was very lucky, but also very unfortunate.Back then, he was selected as one of the first batch of technicians trained in the operation of the most sophisticated and sophisticated machining equipment in China. That was the luck of his master; but because of this, his master lost his freedom for several years, and that was unfortunate.You know, his master was only twenty-two years old at that time.It was not until later that his master's factory moved from the depths of Daba Mountain to the Tianfu Plain, that his master had the opportunity to meet women, fall in love and have children.

Perhaps for this reason, the master of Yun Fei resolutely gave up the absolutely high-paying job at the time and ran out and bought a second-hand CNC machining center to do it alone.When Yun Fei left that world, his master child was only twelve years old!

His master has a deep memory of the first batch of 4-axis CNC machine tools sold to China by West Germany.Because he has been with that machine tool for more than ten years!

The EP6 four-axis linkage machining center is produced by Dirk in the former West Germany. The CNC system is also the DECK CNC system developed by Dirk itself. It is not controlled by PLC, but has an independent control cabinet.

X-axis travel is 2000mm, Y-axis travel is 1200mm, Z-axis travel is 1050mm, select axis A, rotation range is 0°--360°, the spindle can be changed by 90° in manual mechanical mode, from vertical machining center to horizontal Type machining center.

EP6 should be the most advanced four-axis machining center in the world.In particular, the spindle can be freely converted between vertical and horizontal, and can be profiled. The fourth axis rotates around the Z axis. The chain-type tool magazine has a maximum number of tools of 120 tools.

The EP6 type can be stopped at any time, and the spindle can be changed manually and mechanically, and it can be changed to a vertical machining center or a horizontal machining center.If China had enough technical strength at that time, it could completely change the EP6 into a five-axis CNC machining center.At least, the factory where Master Yunfei was in, after the EP6 was bought back, it took several years to organize hundreds of people to carry out transformation and research, but they did not solve the problem that has plagued China until Yunfei left. Drop.

The five-axis linkage machine tool that China can produce can even be said to be a pseudo five-axis linkage CNC machine tool!

EP6 is very powerful, the world's first in German technology, and it has been well reflected.Although one unit of 1.7 million U.S. dollars was a sky-high price back then, Germany's technology in CNC machine tools felt that it was worth the price.There was also a more expensive five-axis machining center, which was even more than five million dollars at the time.

At that time, the EP6 four-axis machining center that accompanied Yunfei's master for more than ten years was finally transferred to a private boss at a low price because the machining accuracy did not meet the requirements of precise military production. He knew that Yunfei left it. In time, the master who often followed him was asked by the private boss to help solve some programming problems.You know, that is a master machine that has been used for more than 20 years. Not only does it have no major problems, but the machining accuracy can be guaranteed to be within 0.02mm.

Dirk has always been the best company in CNC machine tool technology.In the original world of Yunfei, they successfully developed the S22P in 2002, which is the world's only fully automatic super precision five-axis linkage CNC grinding tool that can stably realize high-volume and high-efficiency production of high-efficiency tools (HPC) and high-speed cutting tools (HSC). Centering.Unfortunately, it is not sold to China either.

In fact, most of the mainstream four-axis linkage machine tools in China in later generations are pseudo-four-axis linkage. There are few companies that can produce EP6 compared with the EP6 produced by Dirk 20 years ago!

"It is estimated that they want to make money too much, so they won't let up with that price. We are willing to spend more than six million dollars on their five-axis linkage. Unfortunately, they are also willing to take the money and have no guts to sell equipment. ......" Ren Zhiguo's tone was extremely resentful.

"It doesn't matter. When I build the three-axis machining center with PMC module installed, it will be cheaper to sell you the four-axis machining center. It is definitely cheaper than the Germans..." Yun Fei knows that history has changed. It is really hard to say whether China can still buy high-end CNC machine tools with four-axis linkage.

"Damn it, let's go, Lao Zhao is waiting for you at Huadu Hotel..." When Ren Zhiguo heard Yun Fei's words, he suddenly remembered his purpose of looking for Yun Fei here.

"No, the last time I took the initiative to put his cold face on their hot butt of the military, how did it turn out? Now I have eaten in front of the German guy, and think of running to the little master to find my self-esteem, don't even think about it. ......" Yun Fei ignored Ren Zhiguo's expectant expression.

"Go, it's good to go this time, and it will definitely satisfy you." Ren Zhiguo felt that he was a bit nasty, and for the young man Yun Fei, he actually assumed a posture of a big bad wolf to trick a little white rabbit.

...

"Lao Ren, if you go this time, the results will still be the same as the last time, and I will break your relationship with you in the future! Nima's, obviously the last batch of work was your fault. As a result, I remind you to correct your mistakes. Lao Tzu has to come home. Thank you for having settled the processing fee for us..." Yun Fei scolded and got up from his uncle's hospital bed.

"..." Ren Zhiguo was speechless.

He found that he couldn't argue with Yun Fei anyway.After all, during this period of time, Yun Fei always talked about the processing business that had changed hands. Although he had a thicker skin than the Great Wall, he really couldn't stand Yun Fei's rubbish language.This kid seems to be more woman than a woman. For that matter, he can say the same things to Ren Zhiguo for two or three hours, and then he still has only one meaning, that is, Ren Zhiguo is not kind!

Yun Fei joined Ren Zhiguo’s Blue Bird. Jimin Hospital is not very far from Huadu Hotel. It is estimated that it will take half an hour to drive there.

Yun Fei didn't drive his own car.

Entering the Huadu Hotel again, Yun Fei didn't have the same feeling at the beginning.After all, there is no way for this to compare with later generations of four and five-star hotels. It was shocked for the first time, but it was because the surrounding environment was very poor.
