Super Craftsman

"Impossible! This is absolutely impossible!" The same exclamation sounded several days later in some of the top secret conference rooms in several countries.

"How can Chinese people do the gyro of that precision?" The Japanese are still the last ones, and the old man with white hair is unbelievable.

The layman looks at the excitement and the insider looks at the doorway.

The ordinary students and the visitors saw only the Guinness certification applied by the fine instrument system, and then the gyro created a world record of rotating on the finger when it was rotated for 22 minutes. It was witnessed by three notaries from the Guinness on the spot, and the certificates issued in both Chinese and English were issued on the spot.

Successfully created a world record, many students and the visitors on the scene cheered, and the warm applause lasted for five minutes. The certification site is a lively event.

However, in the eyes of many people, it is not this kind of excitement. Their attention is completely concentrated on the high-precision gyro.

From Professor Wang’s cautious test with rubber gloves, they realized that the processing and assembly accuracy of this high-precision gyro is extremely high. Even the bare-handed oil and sweat are afraid to affect it. How much better?

In fact, from the time of the spin to five minutes, someone has already collapsed. But the **** gyro actually turned around in this situation for a full twenty-two minutes, where is the twenty-two minutes of watching people calmly expecting, clearly distinct as the 22nd of hell. Minutes!

These look at the inside of this scene, where I can think of Professor Wang is very upset, because his hands are not fat, so that the rotation time of high-precision gyro is one minute less, otherwise the record can at least Twenty-three minutes.

Even if it is only twenty-two minutes, it has already made a few sufferings with ulterior motives. Looking at the gyro in the hands of Professor Wang, I can’t immediately grab it and take a closer look.

Fortunately, the school leaders of "grass bag" do not seem to understand the meaning. After getting the certificate, it is also very curious that Professor Chong Wang wants to go over the top to want to see it.

Professor Wang was reluctant, but he couldn’t tell the story of a department leader. He could only ask the school leader to wear a pair of gloves before taking the gyro.

The school leaders saw that the curious foreign guests also wanted to see it. It seems that everything has become a matter of course. Every interested foreigner got the chance to try this delicate gyro with gloves.

Some people have noticed that Professor Wang has been absent-minded in explaining how they design and how to process and assemble. His eyes are always on the top of the top.

A few thoughtful people finally endured the temper, waiting for the people in front to play, and took the precision gyro in the hands and carefully observed.

Only from the mirror effect of the surface of the gyro, the insider can roughly judge the machining accuracy. I felt the smoothness and tranquility of the rotation on the tip of my finger. The experienced person had to admit that the instrument was really out of the way.

Don't look at it as a small gyro, but the technological content contained in the design and processing assembly balance adjustment is definitely the world's top.

Listening to the introduction of Professor Wang, the design and modification were carried out seventeen times, and it took more than a year before and after, dozens of graduate students and doctoral students, plus top operators, the concept of the new design is on the CNC. This is the release of the Guinness Book of Records.

Among them, Professor Wang repeatedly stressed that some people only firmly remembered that Professor Wang only said one sentence or the word that was unknown, and the concept of a new design.

What is discussed in the conference room is the concept of this possible new design.

It seems that the idea of ​​Shuimu University is very strong. In the process of certification, there is still a full video of the TV station. This also allowed people who did not attend the conference to see the scene from the TV.

Although the resolution of the TV is very low, isn't this a live photo of the visitors? Especially the high-precision gyro, the people who are looking for a chance to shoot clearly. The angle is also very full, the front side of the ground all have, it is completely available for everyone's reference.

"Can you do a sample out of the same specifications on the side of Meyer?" the old man asked. I don't believe it, there are videos and photos, and so many people at the scene prove that everyone has to believe.

Fortunately, there are complete photos, they can also make the current processing level of the highest level of Minebea mitsumi (replica one size). (Meiya is the bearing manufacturer of the gyro, Mitsubishi Seiki is responsible for design assembly and testing)

“The photos were sent to Meiya in the evening, and they spent two days building the same top.” The young man in charge of foreign affairs quickly answered the old man’s question.

"How is the result?" Not only the white-haired old man, but others are also very concerned about the results of the copy.

"The thing is here." The young man opened a box on the table, revealing the high-precision gyro inside, and sent it to the old man. I want to say something, but I want to stop talking.

"Say!" The old man saw his hesitation, closed his eyes and waited quietly.

"Meia's processing time is too short, this gyro can only turn for ten minutes." The young people no longer hesitated and said quickly: "They said, give them a month to carefully polish, to ensure that it can reach twenty minutes. the above."

The hardest part of the gyro is the design and selection of materials. The other party has already done this in advance, leaving only the processing and assembly and testing, the difficulty is equivalent to a reduction of 80%. With the processing strength of Meiya, with the drawings, the highest level that can be processed in two days is the limit. Now that Meiya is not the United States that has been in existence for more than two decades, it is not the United States that created a number of bearing records.

“5 micron high-precision CNC has been opened to China, and we have already gotten enough orders, and the evidence has been transferred to European and American counterparts.” The white-haired old man looked at the same fine precision gyro, and his tone was very bad. .

If it was before, seeing that the country can make such a precision top, he must be happy. But now, it has been compared to a hard-working gyro of Shuimu University. How is this human feeling?

"From this gyro, is Shuimu University making breakthroughs in this area?" This is a guess in everyone's mind: "Do we have to reconsider the strategy of high-precision machining centers in China?"

......

The same discussion has taken place in several countries in Europe and America, but the content is similar.

The machining center with higher precision is still blocked. However, in the numerical control of 5 micron precision, all parties in Europe, America and Japan have already opened the blockade, and Chinese domestic enterprises can import freely. However, before the domestic machine tools have not been mass-produced, the price will not fall any more.
