Chapter 727: Be a Sophisticated Wanwan (Part 2)

Before the tea was finished, Guo Tailai received a call from the studio. The few guys who came to threaten had already been taken away by the police forcefully. When they left, the director still made a strong promise that he would definitely uproot this underworld-like group and never let them destroy the construction of the park.

"Send a pennant to the police station." Guo Tailai is no longer the former Guo Tailai, and after receiving the news, he gave instructions after thinking for a while: "Also, please donate a few police cars to the police station. The total amount is 500,000 yuan. See what kind of car they need. The police and the people are fish and water, and the family is easy to talk to!"

When Guo Tailai called, Brother Hai was listening. Hearing Guo Tailai's order, he nodded secretly in his heart. Fatty is getting better at being a man now.

No matter what the reason was for the police station over there to dispatch the police quickly, they always dispatched the police and took the person away. It can be said that Guo Tailai gave him fame and benefits in return, and the people in the police station would feel at ease. It's not purely relying on the relationship from above to suppress people. If anything happens in the future, the police station doesn't need to speak from above, and will definitely actively help the studio. Good thing for a win-win.

This time I went back to the capital mainly to receive Prince Sheikh, and also sold a model design along the way. Basically, things in the capital are similar.

The senior sister was not in the capital, and Guo Tailai didn't want to stay longer. After drinking tea with Brother Hai, the team set off and went straight back to Gusu without even going to the company.

Brother Hai's words made Guo Tailai realize that one should not be too outstanding in his contribution to the country. The research project of Zhengyifang Science and Technology will continue to be researched, but the speed can be slowed down a little. In fact, sometimes the experience of failure is the real accumulation. Otherwise, you only know the correct way to do it, but you don’t know why it is correct and what the results of other methods will be. This is not a complete mastery of this technology.

Professor Wang and the second brother were not disturbed at all. The handling outside was handled by a few security guards. If Guo Tailai hadn't asked them to call the police instead of attacking first, those guys would have been brought down long ago, and it would be the police's turn?

In the past few months, Guo Tailai wanted to study honestly, so when he sat down to discuss with Professor Wang, Guo Tailai also expressed his thoughts and asked Professor Wang and his second brother to help him refer.

"Mr. Wang, look, my master's thesis is made with these machine tool structures." Guo Tailai considered his vocabulary, and asked cautiously: "Doctoral thesis, I can reproduce a LODTM, can I pass it?"

"LODTM?" Professor Wang's eyes lit up suddenly: "Can you reproduce it?"

The second brother next to him also looked expectant, staring at Guo Tailai, waiting for his reply.

The full name of LODTM is LargeOpticsDiamondTurningMachine, large optical parts diamond lathe, which is the most precise large machine tool in the world. Originally designed to make lenses for heat-seeking missiles and other weapons, they are now commonly used in high-precision lenses. Three secondary mirrors were once produced for the Keck Telescope on Mauna Kea, Hawaii's largest island. Keck is currently the largest and best astronomical telescope in the world.

LODTM can handle workpieces with a diameter of 1.65 meters, a height of 0.5 meters, and a mass of 1360 kilograms. It can produce parts with a tolerance of 28 nanometers, which is a thousand times more accurate than ordinary machine tools. To be precise, the shape error in the radial direction is 27.9 nanometers, the roundness and flatness are 12.5 nanometers, and the processed surface roughness is less than 4.2 nanometers.

In order to maintain the machining accuracy of this machine tool, the air temperature in the guardrail where the machine tool is placed is precisely maintained at 20 degrees Celsius, and the air temperature is controlled within the range of plus or minus 0.005 degrees Celsius. The operation can only be started after hours to dissipate the body heat left by the mechanics. When cutting a part, all employees stay outside the guardrail, using cutting oil kept at 20 degrees Celsius to take away the small amount of heat generated by diamond turning.

The frame is made of a super alloy, iron-nickel-cobalt alloy, one of the alloys with the lowest coefficient of thermal expansion of metals. The anti-vibration system is equipped with four air vibration-isolating pads, two of which are connected internally and are automatically balanced when stressed; in addition, there is a granite base, which has a low thermal expansion coefficient and good stability, and its ability to attenuate vibration is 15 times stronger than steel The constant temperature water flows to all parts of the machine tool by gravity; the anti-vibration ditch, the anti-vibration wall and the separate foundation, the partition wall is double-layered, and there is sound-absorbing material in the middle, which can reduce the sound wave vibration. Everything is for precision.

The parabolic mirror used by NASA is also produced by this product. Even more incredible, do you think this product is the latest high-tech product? In fact, the development of this machine tool began in March 1980, and it was officially developed in 1984, which was 16 years ago.

The ultra-large-format CNC machining center that Guo Tailai and Professor Wang cooperated with before surpassed this guy in terms of processing size and format, but it was still slightly insufficient in processing accuracy. Of course, Guo Tailai's "manual" processing ability has reached 20 nanometers, which is definitely higher than this guy.

"If we work harder..." Guo Tailai thought for a while, "I think we can achieve higher precision than it. Of course, I'm not good at operating systems."

"The micro-feeding system, online measurement system, vibration isolation system, and temperature control system involved in it, can you solve these?" Professor Wang stared at Guo Tailai with wide eyes, waiting for his answer with great anticipation.

"I'm also a graduate of the Department of Precision Instruments, okay?" Guo Tailai laughed: "Well, we need to find helpers for temperature control, but aren't the rest all the strengths of our Precision Instruments Department?"

"If you can really do it, what is a doctorate?" Professor Wang directly assured Guo Tailai: "Directly apply for the 863 project. I can't guarantee it for a professor and a doctoral supervisor. I can guarantee it for you as an associate professor and a master's supervisor. If anyone If you are not convinced, come find me!"

"I'm not in school, so what do you want to do with the title of associate professor?" Guo Tailai knew that Professor Wang was too excited, and hurriedly refused: "I plan not to go out during this time, just do this for fun."

Hearing Guo Tailai's last sentence, Professor Wang and the second brother were speechless. If other people do this, it is a scientific and technological breakthrough, but if it is put on Guo Tailai, it is just for fun? But sometimes they really have no way to call Guo Tailai this truth. It seems that Guo Tailai also participated in the large-format processing center last time with a playful attitude.

Regardless of whether Guo Tailai is playing for fun or scientifically and technologically, it is a major challenge for Professor Wang and the 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.

Thinking of this, Professor Wang's body began to tremble involuntarily, not from cold, but from excitement.
