Before the tea was finished, Guo Tailai received a call from the studio. The guys who came and threatened were taken away by the police. When they left, the director promised to uproot this group with a gangster nature and would never let them destroy the construction of the park."

Give a banner to the police station." Guo Tailai is no longer the same as Guo Tailai. After receiving the news, he gave an instruction: "In addition, donate a few police cars to the police station, with a total amount of 500,000 yuan. Please communicate with the police station to see what cars they need. The police and the people are in love, and the whole family is easy to talk to!" Guo

When Tailai called, Brother Hai was listening. Hearing Guo Tailai's instructions, he nodded secretly. The fat man is now becoming more and more adept at being a human being.

No matter what the reason is, the police station there will be quick responses, but the police will take the person away. Guo Tailai's reward can be said to be both famous and profitable, and the people in the police station will feel comfortable. It is not just relying on the relationship above to suppress people. If there is anything in the future, the police station will not have to speak, and will definitely actively help the studio run. A win-win situation.

This time I returned to Beijing, mainly to receive Prince Sheikh, and I also sold a car model design along the way. Basically, things happened in Beijing were almost the same.

My sister was not in the capital, and Guo Tailai didn't think about staying too much. After having tea with Brother Hai, the convoy set off and went straight back to Gusu, without even going to the company.

Brother Hai's words made Guo Tailai realize that dedication to the country should not be too outstanding. The Zhengyifang Technology Research Project continues to be researched, but the speed can be slowed down slightly. Normal research is enough, and Guo Tailai does not need to force the seedlings to grow. In fact, sometimes failure experience is the real accumulation. Otherwise, you only know the correct way, and don't know why this is done correctly. What will happen to other methods? This is not a complete mastery of this technology.

The professor and the second brother were not disturbed at all. The outsiders would have handled all the security guards. If Guo Tailai hadn't asked them to call the police first instead of doing it first, those guys would have been knocked down long ago, would it be the police turn?

A few months later, Guo Tailai had to study honestly, so when he sat down with Professor Wang to discuss it, Guo Tailai also expressed his ideas and asked Professor Wang and his second brother to help refer to it.

Teacher Wang, look, my master's thesis is made of these machine tool structures." Guo Tailai thought about the vocabulary and asked carefully: "Doctoral thesis, I can copy a lodtm, can I pass it?"

lodtm?" Professor Wang's eyes lit up suddenly: "Can you replicate it?"

The second brother of the border also looked expectant, staring at Guo Tailai, waiting for his reply.

The full name of odtm is large  optics  diamond  turning  machine, a large optical parts diamond lathe, it is the most sophisticated large machine tool in the world. It was designed to make lenses for heat-seeking missiles and other weapons, and is now widely used in high-precision lenses. Three secondary reflectors were once produced for the Keck Telescope, the largest island of Hawaii, Mount Monakea. Keck is currently the largest and best astronomical telescope in the world.

Lodtm can process workpieces with diameters up to 1.65 meters, up to 0.5 meters, and mass up to 1,360 kilograms. It can produce parts with tolerances of 28 nanometers, which is one thousand times more accurate than ordinary machine tools. To be precise, the radial shape error is 27.9 nanometers, the roundness and flatness are 12.5 nanometers, and the processing surface roughness is less than 4.2 nanometers.

In order to maintain processing accuracy, this machine tool has the temperature precision placed in the guardrail of the machine tool to ensure that the temperature is maintained at 20 degrees Celsius, and the air temperature is controlled within the range of positive and negative 0.005 degrees Celsius. The preheating time is 1-2 days. The operation can only be started after at least twelve hours after the machine tool is installed to dissipate the body temperature left by the mechanic. When cutting a part, all employees stay outside the guardrail and use cutting oil maintained at 20 degrees Celsius to take away the small amount of heat generated by diamond turning.

The frame is made of iron-nickel-cobalt alloy, one of the special alloys with the lowest thermal expansion coefficient of metal. The anti-vibration system is equipped with four air vibration isolation pads, two of which are connected internally and are automatically balanced when under stress. In addition, there is a granite base, which has a low thermal expansion coefficient of granite and good stability, and its attenuation ability to vibration is 15 times stronger than that of steel; constant temperature water flows to various parts of the machine tool by gravity; anti-vibration grooves, anti-vibration walls and separate foundations, and the partition walls are double-layered, with sound-absorbing materials in the middle, which can reduce sound wave vibration. Everything is to ensure accuracy.

The parabolic mirror used by NASA is also produced by this product. What’s even more incredible is that you think this product is the latest high-tech product? In fact, this machine tool started to be developed in March 1980 and was officially developed in 1984, sixteen years ago.

The super-large-format CNC machining center that Guo Tailai and Professor Wang collaborated with the former is that the processing size exceeds this guy, and the processing accuracy is still slightly insufficient. Of course, Guo Tailai's "handmade" processing ability now has reached 20 nanometers, which is definitely higher than this guy."

If I try harder..." Guo Tailai thought for a while: "I think we can have a little more accuracy than it. Of course, I'm not good at operating systems."

"You can solve all the micro feeding system, online measurement system, vibration isolation system, and temperature control system involved?" Professor Wang widened his eyes, stared at Guo Tailai, waiting for his answer with great anticipation.

"I'm also a graduate of the Department of Sampling and Instrument, okay?" Guo Tailai laughed: "Well, I need help with the temperature control, but aren't the rest of our Department of Sampling and Instrument?"

If you can really do it, what is a doctorate degree?" Professor Wang directly guaranteed Guo Tailai: "I can't guarantee the professor's doctoral supervisor directly. Associate professor and master's supervisor, I promise I can get it for you. If anyone is not convinced, come to me!"

"I'm not in school, what do I need to do if I have an associate professor title?" Guo Tailai knew that Professor Wang was too excited and hurriedly refused: "I've been planning to go out during this period and have fun."

When they heard Guo Tailai's last sentence, Professor Wang and his second brother looked speechless. Others did this, which was a technological breakthrough. If Guo Tailai was just doing this, they were just doing this. But sometimes they really couldn't call Guo Tailai this. It seemed that the large-format processing center last time seemed to be involved with a playful attitude.

Whether Guo Tailai is playing or researching technology, it is a major challenge for Professor Wang to second brother. If this machine tool can be successfully developed, the domestic ability to process ultra-high-precision optical lenses will make an indescribable leap.

When he thought of this, Professor Wang's body began to tremble involuntarily, not cold, but excited.
