Chapter 44 Another Trap (Part 2)

"Impossible! This is absolutely impossible!" A few days later, the same exclamation sounded in some top-secret conference rooms in different countries.

"How could the Chinese be able to make a spinning top with that kind of precision?" The Japanese were still the same people as last time, and the one who couldn't believe it was the old man with gray hair.

Laymen watch the excitement, while experts watch the doorway.

Ordinary students and visitors only saw that the Department of Precision Instruments applied for a Guinness certification, and then the spinning top created a world record for spinning on a finger when it spun for a full 22 minutes. Witnessed by three Guinness notaries at the scene, they filled in and issued a certificate in both Chinese and English on the spot.

The successful creation of the world record caused many students and visitors to cheer, and the warm applause lasted for five minutes. The certification scene became lively.

However, in the eyes of many people, what they saw was not this kind of excitement. Their attention was completely focused on the high-precision spinning top.

From Professor Wang's extremely cautious experiment with rubber gloves, they understood that the processing and assembly precision of this high-precision gyroscope is probably extremely high, and even the oil and sweat of bare hands are afraid of affecting it, so how powerful is it?

In fact, from the moment the rotation reached five minutes, some people were already about to collapse. But that damned spinning top spun alive for a full twenty-two minutes in this situation. That's not the twenty-two minutes of watching people hold their breath and wait, it's clearly the twenty-two minutes that make people feel like falling into hell. minutes!

These experts who watched this scene, how could they have imagined that Professor Wang was extremely annoyed, because his hand was not as stable as a fat man, so that the rotation time of the high-precision top was shortened by one minute, otherwise, this record would at least be reached. Twenty-three minutes.

Even if it was only twenty-two minutes, it has already caused a few experts with ulterior motives to suffer incomparably. Looking at the spinning top in Professor Wang's hand, they wished they could grab it immediately and take a closer look.

Fortunately, the school leaders of the "idiot" didn't seem to understand the meaning of it. After getting the certificate, Professor Wang, who was still very curious, asked for the spinning top to have a look.

Professor Wang was reluctant, but he couldn't resist the intercession of a department leader. He could only ask the school leader to wear a pair of gloves before taking the spinning top.

The school leaders saw it, and curious foreign guests also wanted to see it. It seemed that everything became a matter of course. Every interested foreign guest was given the opportunity to try this delicate spinning top while wearing gloves.

Interested people have also noticed that Professor Wang has been absent-minded when explaining how they design, process and assemble, and his eyes are always on the spinning top.

A few caring people finally had patience, and after waiting for the people in front to play, they took the precision top in their hands and observed it carefully.

Only from the mirror effect on the surface of the gyroscope, experts can roughly judge the processing accuracy. Feeling the smoothness and tranquility of the rotation on the fingertips again, experienced people have to admit that the Precision Instrument Department has really come up with something extraordinary this time.

Although it is just a small spinning top, the technical content of design, processing, assembly and dynamic balance adjustment contained in it is definitely the top in the world.

Listening to the introduction of Professor Wang, the design and modification were carried out 17 times, and it took more than a year. Dozens of graduate students and doctoral students, plus top operators, the newly designed concept CNC , This is the press conference for applying for the Guinness Book of Records.

Professor Wang has repeatedly emphasized the hard work involved, but some people only firmly remember the word that Professor Wang only said in one sentence, which is still vague, the newly designed concept CNC.

What is being discussed in the conference room now is this possible new design concept CNC.

It seems that Shuimu University has a strong idea of ​​showing off, and there is even a TV station recording the whole process during the certification process. This also allowed people who did not attend the press conference to watch the scene on TV.

Although the resolution of the TV is very low, isn't there still a live photo of the visitors? Especially the high-precision gyroscope, the caring people took the opportunity to shoot it very clearly. The angles are also very comprehensive, including the front, side and ground, which can be used for everyone's reference.

"Can Minebea make a sample according to the same specifications?" asked the old man. If you don't believe it, there are videos, photos and so many people at the scene to prove it, everyone has to believe it.

Fortunately, there are complete photos, and they can also ask MinebeaMitsumi, which has the highest processing level at present, to reproduce one according to the size. (Minebea is the manufacturer of the gyro bearing, and Mitsubishi Seiki is responsible for the design, assembly and testing)

"The photo was sent to Minebea that night, and they spent two days building the same spinning top." The young man in charge of foreign affairs liaison quickly answered the old man's question.

"What's the result?" Not only the white-haired old man, but others are also concerned about the result of the replication.

"It's here." The young man opened a box on the table, revealing the high-precision spinning top inside, and handed it to the old man. I wanted to say something, but stopped talking.

"Speak!" Seeing his hesitation, the old man closed his eyes and waited quietly.

"Minebea's processing time is too short. This spinning top can only spin for ten minutes." The young man stopped hesitating and said quickly: "They said, give them a month to polish it carefully, and guarantee that it can reach twenty minutes. above."

The most difficult part of the spinning top is the design and material selection. The other party has already done these in advance, and only the processing, assembly and testing are left, which is equivalent to an 80% reduction in difficulty. With Minebea's processing capabilities, the highest grade that can be processed within two days is the limit if there are blueprints. Now Minebea is not the Minebea more than 20 years later, and it is not the Minebea who has created many bearing records.

"The 5-micron high-precision CNC has been opened to Huaxia, and we have already obtained enough orders first, and the evidence has been transferred to European and American counterparts." The white-haired old man looked at the same exquisite precision gyroscope, and said in a very unfriendly tone. .

If it was in the past, he must have been just happy to see that the country could make such a precision spinning top. But now, it was compared abruptly by a spinning top from Shuimu University. How can this be called human?

"But judging from this gyro, has Mizuki University made a breakthrough in this area?" This is the guess in everyone's mind: "Should we reconsider the strategy of high-precision machining centers toward China?"

...

The same discussion also took place in several countries in Europe and the United States, but the content is similar.

Higher-precision machining centers are definitely still blocked, but on the CNC with 5-micron precision, all parties in Europe, America and Japan have unanimously opened the blockade, and domestic enterprises in China can freely import. However, before the domestic machine tools are mass-produced, the price will not drop again.
