Chapter 104

"Shit, don't mention it. If we can reach an agreement, why do we ask you. Those vampires in West Germany know that we urgently need to get a four-axis machining center. When the price comes to $1.96 million, they bite to death. Now the negotiations have reached an impasse, and Lao Zhao is so angry that he jumps and curses all day... "Ren Zhiguo doesn't want to pay attention to Yun Fei at this time, so he won't raise the price.

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

It turns out that in his world, Dirk company in West Germany is the first guy to sell to China's four-axis linkage machining center. Yun Fei knew this very well, because the master who taught him NC machining center programming at that time was the first person who came into contact with the four-axis machining center within the aerospace system.

For the CNC machine tool of West Germany Dirk company, it can be called an artifact in master Yun Fei's mouth.

In 1990, shortly before the unification of the Democratic Republic of Germany and the Federal Republic of Germany, China successfully colluded with West Germany, that is, the best manufacturer of CNC machining centers in the Federal Republic of Germany, and purchased a batch of four-axis CNC machine tools at the price of $1.7 million. The master of Yunfei doesn't know the specific quantity. As long as he knows, he knows that there can't be a lot of this quantity. As for his master's factory, it was because their factory at that time mainly belonged to military production, and the products produced all over the world belonged to top technology.

Many people in later generations know that the international situation faced by China at that time was very complex. For the sake of national defense and security, China began to build the third front soon after the founding of the people's Republic of China. The few high tech and advanced technology factories and weapons factories in Chinese mainland have been moved to Bashu basin.

In particular, the most important missile production, especially the production of intercontinental missiles, is placed deep in the 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 in the hollowed out Dabashan.

It is said that only it is said that a large part of the carriers of China's underground Great Wall project are provided by factories deep in Daba Mountain. Cloud not only heard the legend and turned it on the Internet for several months, but did not get accurate information to prove the authenticity of the legend.

Bashu has high mountains and many mountains, and is backed by the highest Himalayas in the world. It belongs to the last place in China. At that time, it was very difficult for imperialists to use planes or warships to blow up and build in the depths of Bashu mountains far away from the sea. Therefore, at that time, China's most sophisticated equipment and weapons manufacturing were located in the depths of Daba Mountain in the rear of China.

At that time, the western countries only relaxed a little bit of control over China's Chinese mainland's three axis machining center, and China's strategic high-end CNC machine tools with four axes should not be counted on. Yun Fei heard from his master that at that time, China was actually very eager to buy five axis CNC machine tools and wander around the world. It happened to meet the undercurrent surging, splitting Germany, which has been divided for 45 years and is about to be reunified.

It is also said that at that time, West Germany sold it to China's four axis machining center because of domestic capital problems. They also want to sell the five axis machining center. Unfortunately, the Toshiba incident in Japan has not been long. Although the Batumi embargo Committee has been dissolved, the world police of the United States and the members of the North Atlantic Treaty Organization are staring at these strategic military production equipment.

Finally, I don't know how to transport it back. Anyway, there is no word in the whole world. German Dirk company sold it to China's four-axis machining center in the early 1990s. After the successful transaction, China also wants to continue to buy more four-axis machining centers. With the disintegration of the Soviet Union, the reunification of Germany and the end of the cold war, those countries that do not engage in the cold war with Lao maozi have more time and energy to stare at their allies' private activities with the red camp.

Yun Fei's master who taught him NC machining center programming was lucky and unfortunate. In that year, he was selected as the first batch of technicians to train the operation of the most high-precision and cutting-edge machining equipment in China, which was the luck of his master; But his master lost several years of freedom because of this, that is misfortune. You know, his master was only 21 or 12 years old at that time. It was not until his master's factory moved from the depths of Daba mountain to the Tianfu plain that his master had 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 his absolutely high paying job at that time and went out to buy a second-hand CNC machining center to work alone. When Yun Fei left the world, his master child was only twelve years old!

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

Ep6 four-axis linkage machining center is produced in the former Dirk company in West Germany. The equipped numerical control system is also the deck numerical control system developed by Dirk company. It is not controlled by PLC, but has an independent control cabinet.

The travel of x-axis is 2000mm, the travel of y-axis is 1200mm, and the travel of z-axis is 1050mm. Select axis A, and the rotation range is 0 ° -- 360 °. The spindle can change 90 ° under the mode of manual machinery, from a vertical machining center to a horizontal machining center.

Ep6 should be the most advanced four-axis linkage machining center in the world. In particular, the spindle can be freely converted between vertical and horizontal, and profiling processing can be carried out. The fourth axis rotates around the z-axis direction. The chain type tool magazine has a maximum number of 120 tools.

Ep6 can be shut down at any time, and the spindle can be changed into vertical machining center or horizontal machining center by manual machinery. If China had enough technical strength at that time, it could completely change ep6 into a five axis CNC machining center. At least, after the ep6 was bought back, master Yunfei's factory spent several years organizing hundreds of people to carry out transformation and research, and did not solve the problem that plagued China until Yunfei left.

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 German technology ranks first in the world. It has been well reflected from it. Although 1.7 million US dollars was a sky high price in those years, Germany's technology in CNC machine tools was worth that price. There was also a more expensive five axis linkage machining center, which even cost more than $5 million at that time.

The ep6 four-axis linkage machining center that accompanied master Yun Fei for more than ten years was finally transferred to a private boss at a low price to continue to create value because the machining accuracy could not meet the requirements of precision military products production. Knowing that master Yun Fei left, he often followed his master and was asked by the private boss to help solve some programming problems. You know, it's 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 company has always been the enterprise with the best CNC machine tool technology. In Yunfei's original world, the s22p successfully developed by them in 2002 is the only fully automatic super precision five axis CNC grinding center in the world that can stably realize the mass and high-efficiency production of high-efficiency cutting tools (HPC) and high-speed cutting tools (HSC). Unfortunately, it is also not sold to China.

In fact, most of the mainstream four-axis linkage machine tools in later China are pseudo four-axis linkage, and there are few enterprises that can produce ep6 compared with that produced by Dirk company 20 years ago!

"It's estimated that they just want to make money, so they don't let go with that price. We are willing to pay more than $6 million for their five axis linkage. Unfortunately, they are also willing to take money and have no courage to sell equipment... "Ren Zhiguo's tone is very sad.

"It doesn't matter. When I get the one with PMC module installed on the three-axis machining center, I'll sell it to you at a low price. It's definitely cheaper than the German people..." Yun Fei knows that history has changed. It's really hard to say whether China can buy a high-end four-axis CNC machine tool now.

"Shit, waste god horse words, let's go. Lao Zhao is waiting for you at Huadu Hotel..." when Ren Zhiguo heard Yunfei say this, he suddenly remembered his purpose of looking for Yunfei here.

"No, last time I took the initiative to put my cold face on their military's hot ass. what was the result? Now I'm suffocating in front of the German, and don't even think about running to the little master to recover my self-esteem... "Yun Feisi ignored Ren Zhiguo's look of expectation.

"Go. It's good to go this time. It can definitely satisfy you." Ren Zhiguo felt that he was a little cheap. For Yun Fei, a young man, he actually made a big gray wolf to deceive the little white rabbit.

……

"Lao Ren, if you go this time, the result will still be the same as last time. I'll break up with you in the future! Nima's, it's clear that the last batch of work was your fault. As a result, I remind you to correct your mistakes. I have to come 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 he could not quarrel with Yun Fei anyway. After all, Yunfei always talks about the processing business that changed hands these days. Although his skin is thicker than the turn of the Great Wall, he really can't stand Yunfei's garbage language. This boy, as if he were a woman more than a woman, could say the same thing to Ren Zhiguo for two or three hours without the same words, and then there was only one meaning, that is, Ren Zhiguo was unkind!

Yunfei went to Ren Zhiguo's Bluebird. Jimin hospital is not far from Huadu Hotel. It is estimated that it will take half an hour to get there by car.

Yunfei didn't drive his own car.

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