"Damn, don't mention it, if we can negotiate, why are you looking for it? The vampires in West Germany know that we urgently need a four-axis linkage machining center, and the price is 190 million dollars, and they will not let go. Now The negotiation has come to an impasse, and Lao Zhao is so angry that he jumps up and scolds people all day..." At this time, Ren Zhiguo didn't want to pay attention to whether Yun Fei would raise his price because of this.

"No? Don't they really want to make money?" Yun Fei asked Ren Zhiguo in surprise.

It turned out that in his world, Decker Company in West Germany was the first guy to sell a four-axis machining center to China.For this matter, Yunfei knew 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 to contact the four-axis machining center.

As for the CNC machine tool of STUDEC, in the mouth of Master Yunfei, it can be called a magic tool.

In 1990, shortly before the reunification of the Democratic Republic of Germany and the Federal Republic of Germany, China successfully hooked up with West Germany, that is, the best CNC machining center manufacturer in the Federal Republic of Germany, and purchased a batch of four-axis linkage at a price of 170 million US dollars. CNC machine tools.Yunfei's master didn't know the exact number, but anyone who knew it would know that it was absolutely impossible to have a large number.As for his master's factory, it was because their factory at that time was mainly for military production, and the world's top-tech things were produced.

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

In particular, the most important missile production, especially the production of intercontinental missiles, is placed 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 factories are built inside the hollowed out Daba Mountain.

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

The land of Bashu has high mountains and many mountains, and it is backed by the highest Himalayas in the world. It belongs to the last part of China.At that time, it was very difficult for the imperialists to use planes or warships to blow up the Bashu Mountains, which were built so far away from the sea.Therefore, it was the most sophisticated equipment in China at that time.As well as the most sophisticated and cutting-edge weapon manufacturing, they are all located in the depths of Daba Mountain, which is located in the entire rear of China.

At that time, Western countries only slightly relaxed the control of three-axis machining centers in mainland China. China should not count on strategic high-end CNC machine tools with four axes or more.Yun Fei heard from his master that at that time, China was really hoping to buy a five-axis CNC machine tool to roam around the world.Just in time for the undercurrent to surge, Germany, which has been divided for 45 years and is about to be unified.

It is said, and it is also said that West Germany had domestic funding problems at that time.It was sold to a Chinese four-axis machining center.They also wanted to sell the five-axis machining center, but unfortunately, the Toshiba incident in Japan happened not long ago, although the Batumi embargo committee has been disbanded.But there is also the United States, the world police, and the various member states of the North Atlantic Treaty Organization are staring at these strategic military production equipment.

In the end, I don’t know how to transport it back. Anyway, there is no rumor in the whole world that the German company Dirk sold it to China’s four-axis linkage machining center in the early 90s.After the success of that transaction, China also wants 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.Those countries that do not engage in the Cold War with the old Maozi have more time and energy to keep an eye on their allies' private dealings with the red camp.

Yunfei's master who taught him the programming of the CNC machining center was very lucky, but also very unfortunate.It was his master's luck to be selected as the first batch of technicians in China to train the operation of the most sophisticated machining equipment; but it was unfortunate that his master lost his freedom for several years because of this.You know, his master was only 21 years old at that time.It wasn't 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 it was also for this reason that Yunfei's master resolutely gave up his job, which was regarded as an absolute high salary at that time, and ran out to buy a second-hand CNC machining center to do it alone.When Yun Fei left that world, his master's child was only 12 years old!

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

The ep6 four-axis linkage machining center was produced in the former West German Deck company. The CNC system equipped with it is also a deck CNC system developed by Decker company itself. It is not controlled by PLC, but has an independent control cabinet.

The x-axis stroke is 2000mm, the y-axis stroke is 1200mm, the z-axis stroke is 1050mm, the axis a is selected, the 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.

The ep6 type should be regarded as the most advanced four-axis linkage machining center in the entire world.In particular, the main shaft can be freely switched between vertical and horizontal, and can be used for profiling processing. The fourth axis rotates around the z-axis direction. The chain-type tool magazine can hold up to 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 into a vertical machining center or a horizontal machining center.If China had sufficient technical strength at that time, it could completely change the EP6 into a five-axis linkage CNC machining center.At least, the factory that Master Yunfei was in back then spent several years organizing hundreds of people to carry out renovations after buying EP6, but they did not solve the problem that plagued China until Yunfei left. Lose.

The five-axis linkage machine tools that can be produced in China can even be said to be pseudo-five-axis linkage CNC machine tools!

ep6 is very powerful, and the German technology is the world's number one, which is well reflected from it.Although US$170 million was considered a sky-high price back then, Germany's technology in CNC machine tools was considered worthy of that price.There is also a more expensive five-axis linkage machining center, and the price even exceeded $500 million at the time.

At that time, the ep6 four-axis linkage machining center that accompanied Master Yunfei for more than ten years was finally transferred to a private boss at a low price because the machining accuracy could not meet the requirements of sophisticated military production. During the period, the master who often followed him was invited by the private boss to help solve some programming problems.You know, that is a classic machine that has been used for more than 20 years. Not only does it not have any major problems, but the machining accuracy can be guaranteed to be within 0.02mm.

Deke company has always been the best enterprise in CNC machine tool technology.In Yunfei’s original world, the s2002p they successfully developed in 22 is the only fully automatic super-precision five-axis linkage CNC grinding machine in the world that can stably achieve high-volume, high-efficiency production of high-efficiency cutting tools (hpc) and high-speed cutting tools (hsc). Cut the center.Unfortunately, it is also not sold to China.

In fact, most of the mainstream four-axis linkage machine tools in China in later generations are pseudo four-axis linkages. There are almost no companies that can produce ep20s produced by Dirk 6 years ago!

"I guess they want to make money too much, so they won't let go when they hold the price. We are willing to spend more than 600 million US dollars to buy their five-axis linkage, but unfortunately they also want to take money and have no courage to sell equipment... ..." Ren Zhiguo's tone was extremely resentful.

"It doesn't matter, wait until I get the one with the PMC module installed on the three-axis machining center, and sell it to you at a lower price than the four-axis machining center, which is definitely cheaper than the Germans..." Yun Fei knew that history had changed, It is really hard to say whether China can still buy high-end CNC machine tools with four-axis linkage.

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

"No, last time I took the initiative to use my cold face to stick their military's hot ass, how did it turn out? Now that I have suffered in front of the Germans, I don't even think about running in front of the young master to regain my self-esteem ..." 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 cheap, and for Yun Fei, a young man, he actually acted like a big bad wolf to lure the little white rabbit.

……

"Old Ren, if you go this time and the result is still the same as last time, I will break off relations with you in the future! Damn, it was obviously your fault for the batch of jobs last time, but I reminded you to correct your mistakes, and I have to come to the door Thank you for paying us the processing fee..." Yun Fei got up from his uncle's hospital bed cursing.

"..." Ren Zhiguo was speechless.

He found that no matter what, he couldn't argue with Yun Fei.After all, during this period of time, Yun Fei was always talking about the processing business that had been transferred. Although his skin was thicker than that of the Great Wall, he really couldn't stand Yun Fei's rubbish language.This kid seems to be more feminine than a woman. As for that matter, he can say the same thing to Ren Zhiguo for two or three hours without saying the same thing, and then he still has only one meaning, that is, Ren Zhiguo is not kind!

Yun Fei went to Ren Zhiguo's Bluebird. Jimin Hospital is not very far from Huadu Hotel, and it takes about half an hour to drive there.

Yunfei didn't drive his own car.

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