PS: I couldn't kneel anymore and fell down...... screamed hoarsely, begging everyone to have pity on the poor gourd, give some subscriptions, give some monthly passes......

"Damn, don't mention it, if we can talk about it, what are I looking for you to do. Those vampires in West Germany know that we urgently need to get a four-axis linkage machining center, and the price is 1.96 million US dollars. Now that the negotiations have reached an impasse, Lao Zhao was so angry that he jumped to his feet and scolded people all day long...... "Ren Zhiguo doesn't want to pay attention to Yun Feihui at this time, so he won't raise the price because of this."

"Not really, right? Don't they really want to make money? Yun Fei asked Ren Zhiguo in surprise.

It turned out that in his world, Dirk Company in West Germany was the first guy to sell to China's four-axis linkage machining center. For this matter, Yun Fei knew very clearly, because the master who taught him the programming of the CNC machining center at that time was the first person to contact the four-axis machining center within the aerospace system.

For the CNC machine tool of Sieddek Company, in the mouth of Master Yunfei, it can be called an artifact.

In 1990, shortly before the reunification of the GDR and the Federal Republic of Germany, China successfully colluded with West Germany, the best CNC machining center manufacturer in the Federal Republic of Germany, and purchased a batch of four-axis CNC machine tools at a price of 1.7 million US dollars. What is the specific number, Yun Fei's master doesn't know the Dao, as long as he understands the person, he knows that the number of the Dao is definitely not possible. As for his master's factory, it was because the factory they had at that time mainly belonged to military production, and the entire world of production belonged to the top technology.

Many people in later generations knew that the international situation facing China at that time was very complicated, and out of consideration for national defense and security, it began to engage in third-line construction soon after the founding of the People's Republic of China. The few high-precision and cutting-edge technology factories and weapons production factories in Chinese mainland were moved to the Bashu Basin.

In particular, the most important missile production, 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 other models, most of the assembly plants are built inside the hollowed-out Daba Mountain.

It is said, it is just said. A large part of the underground Great Wall project in China was carried by factories deep in the Daba Mountains. Yun Fei not only heard this legend, but searched the Internet for several months, but did not get any information that can prove the authenticity of this legend.

The land of Bashu is high and mountainous, and it is backed by the Himalayas, the highest in the world, and belongs to the rear of China. It was very difficult for imperialism to use airplanes or warships to blow up the Bashu Mountains, which were built in the depths of the Bashu Mountains, which were incomparably far away from the sea. Therefore, at that time, China's most sophisticated and cutting-edge equipment. and the manufacture of the most sophisticated and sophisticated weapons, all in the depths of Daba Mountain, the rear of the entire China.

At that time, Western countries only slightly relaxed the control of three-axis machining centers in Chinese mainland, and China did not expect strategic-level high-end CNC machine tools above four axes. Yun Fei heard his master say that at that time, China actually hoped to be able to buy five-axis linkage CNC machine tools, and swayed around the entire world. It coincided with the undercurrent of turbulence, the 45-year-long division of Germany that was about to be reunified.

It is said, it is also said, that at that time West Germany was due to domestic financial problems. It was sold to a four-axis machining center in China. They also wanted to sell the five-axis machining center, but unfortunately, the Toshiba incident in Japan did not come out for long, although the Batumi embargo committee has been dissolved. But there is also the United States, the world's policeman, and the eyes of the various member states of the North Atlantic Treaty Organization are fixed on these strategic-level military production equipment.

I don't know how to transport it back, anyway, there is no rumor in the whole world, and the German Dirk company sold it to China in the early nineties of the twentieth century. After that deal was successful, China also wanted to continue to buy more four-axis machining centers. With the collapse of the Soviet Union and the reunification of Germany, the Cold War ended. Countries that don't engage in a Cold War with Lao Maozi have more time and energy to keep an eye on their allies' private dealings with the red camp.

Yun Fei's master who taught him the programming of the CNC machining center was lucky, but also unlucky. At that time, he was selected as the first batch of technicians in China to train the operation of the most high-precision and cutting-edge machining equipment, which was the luck of his master; But because of this, that master lost his freedom for several years, and that was unfortunate. You must know that his master was only twenty-one or twelve years old at that time. It wasn't until later that his master's factory was relocated from the depths of Daba Mountain to the Tianfu Plain, that his master was able to have the opportunity to contact women, fall in love and have children.

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

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

EP6 four-axis linkage machining center, produced in the original West German Dirk company, equipped with the CNC system is also the DECKER company developed and developed DECK CNC system, not PLC control, but has an independent control cabinet.

X-axis travel 2000mm, Y-axis travel 1200mm, Z-axis travel 1050mm, select axis A axis, rotation range 0 ° - 360 °, spindle can be transformed 90 ° in the way of manual machinery, from vertical machining center to horizontal machining center.

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

The EP6 can be stopped at any time, and the spindle can be changed by manual machine to a vertical machining center or a horizontal machining center. If China had enough technical strength at that time, it would have been possible to change EP6 into a five-axis linkage CNC machining center. At least, the factory where Master Yun Fei was back then, after EP6 was bought, it took several years to organize hundreds of people to carry out renovation and research, but it did not solve the problem that plagued China until Yun Fei left.

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

The EP6 is very powerful, and it is the first in the world of German technology, and it has been well reflected from it. Although 1.7 million US dollars was a sky-high price at the time, Germany's technology in CNC machine tools felt that it was worth the price. There were also more expensive five-axis simultaneous machining centers, which cost more than five million US dollars at the time.

The EP6 four-axis linkage machining center that accompanied Yun Fei's master for more than ten years was transferred to a private boss at a low price to continue to create value because the machining accuracy could not meet the precise military production requirements. To know that it is a classic machine that has been used for more than 20 years, not only does it not have any major problems, but the processing accuracy can also be guaranteed to be within 0.02mm.

Dirk company has always been the best enterprise in CNC machine tool technology. In the original world of Yunfei, they successfully developed S22P in 2002, which is the only fully automatic super precision five-axis linkage CNC grinding center in the world that can stably achieve large-scale and high-efficiency production of high-efficiency tools (HPC) and high-speed cutting tools (HSC). It's a pity that the same is not sold to China.

In later generations, most of China's mainstream four-axis linkage machine tools, in fact, are pseudo-four-axis linkage, and can produce EP6 enterprises compared with Dirk 20 years ago.

"I guess they just want to make money too much, so they won't let go of the price. We are willing to pay more than six million US dollars to buy their five-axis linkage, but unfortunately they also have the heart to take the money, and they don't have the courage to sell the equipment......" Ren Zhiguo's tone was extremely resentful.

"It doesn't matter, when I add a PMC module to the three-axis machining center, I will sell you a four-axis linkage machining center cheaply, which is definitely cheaper than the Germans...... "Yun Feizhi said, history has changed, and whether China can still buy high-end CNC machine tools with four-axis linkage is really a bit difficult to say.

"Damn, nonsense, let's go, Lao Zhao is waiting for you at the Huadu Hotel......" Ren Zhiguo heard Yun Fei say this, and suddenly remembered the purpose of his coming here to find Yun Fei.

"No, last time Lao Tzu took the initiative to stick his cold face to their military's hot ass, what was the result? Now that I was stunned in front of the Germans, I thought of running to the master to regain my self-esteem, and I didn't even think about it......" Yun Fei ignored Ren Zhiguo's expectant expression.

"Go ahead, there are benefits to going this time, and it will definitely satisfy you." Ren Zhiguo felt that he was a little cheap, and for Yun Fei, a young man, he actually made a posture of a big bad wolf to deceive the little white rabbit.

……

"Lao Ren, if you go this time, it will still be the same as last time, and Lao Tzu will break off relations with you in the future! Nima's, obviously the last batch of work was your fault, but the result reminded you to correct your mistakes, Lao Tzu still has to go to the door to thank you and settle the processing fee for us......" Yun Fei scolded and got up from his uncle's hospital bed.

"......" Ren Zhiguo was speechless.

He found that no matter what, he couldn't quarrel with Yun Fei now. After all, during this time, Yun Fei always talked about the processing business that changed hands, although his skin was thicker than the corner of the Great Wall, but he really couldn't stand Yun Fei's garbage language. This kid seems to be more feminine than a woman, just about that matter, he can say the same thing to Ren Zhiguo for two or three hours without the same words, and then there is still only one meaning, that is, Ren Zhiguo is not kind!

Yun Fei is on Ren Zhiguo's Blue Bird, Jimin Hospital is not very far from Huadu Hotel, and it is estimated that it can be reached in half an hour by car.

Yun Fei didn't drive his own car.

When he entered the Huadu Hotel again, Yun Fei did not have the same feeling as at the beginning. After all, there is no way to compare this with the four or five-star hotels of later generations, and it was shocked for the first time, but it was just because the surrounding environment was very poor.
