Chapter 363： Be a sophisticated game (below)

The tea has not been finished yet, Guo Tailai received a call from the studio. The guys who came to threaten have been taken away by the police. When they left, the director’s promised vowedly would uproot this group with a triad nature and never let them destroy the park. "

Send a banner to the police station. Guo Tailai is no longer the former Guo Tailai. After receiving the news, he made an instruction: "In addition, donate a few police cars to the police station, totaling 500,000. Communicate with the police station to see what cars they need." The policeman is so fishy, ​​the family is good to talk! Guo

When Thai came to call, Hai Ge listened at the side. When I heard Guo Tailai’s instructions, my heart also secretly nodded. Fat people are getting more and more people now.

No matter what the reason is, the police station quickly dispatched the police. It is always the police who took the people away. Guo Tailai’s return is so good that it can be given to the name and benefit, and the people at the police station will feel comfortable. It is not purely relying on the above relationship to press people. If there is anything in the future, the police station will not have to talk to the top, and will definitely help the studio to run away. A win-win good thing.

This time back to Beijing, mainly to receive Prince Sheikh, but also sold a model design, basically the same thing in Beijing. division

The sister is not in the capital, Guo Tailai did not want to stay more, and after drinking tea with Haige, the team set off and went back directly to Gusu, even the company did not go.

Hai Ge’s words made Guo Tailai realize that the dedication to the country should not be too outrageous. The project of the Science and Technology Research Institute of Zhengfang continued to study, but the speed could be slowed down a bit. Normal research would be fine, and Guo Tailai would not be forced to promote the seedlings. In fact, sometimes the experience of failure is the real accumulation. Otherwise, I only know the correct way. I don’t know why this is done correctly. What other methods will have results. This is not a complete mastery of this technology. king

The professor and the second brother were not disturbed at all, and there were several security guards on the outside. If Guo Tailai asked them to call the police first instead of first, those guys had already been laid down, and could it be the turn of the police? This

Guo Tailai had to learn honestly for a few months, so when he sat down with Professor Wang to discuss, Guo Tailai also said his thoughts to let Professor Wang and his second brother help. "

Teacher Wang, you see, my master thesis is done with these machine tools. Guo Tailai thought about the vocabulary and carefully asked: "Doctor's thesis, I am engraving a lodtm, can you pass?" ""

Lodtm? "Professor Wang's eyes jerked brightly: "Can you re-enact?" Next to

The second brother of the side is also looking forward to look at Guo Tailai, waiting for his reply. l

The odtm full name is largeopticsdiamondturningmachine, a large optical parts diamond lathe, which is the world's most sophisticated large machine tool. The initial design was to make lenses for hot-seeking missiles and other weapons, and is now commonly used for high-precision lenses. Three secondary mirrors were produced for the Keck telescope in Mauna Kea, Hawaii's largest island. Keck is currently the largest and best astronomical telescope in the world.

Lodtm can handle workpieces up to 1.65 meters in diameter, up to 0.5 meters in diameter and weighing up to 1360 kilograms. It can produce parts with a tolerance of 28 nanometers, which is exactly one thousand times more accurate than ordinary machine tools. Specifically, the radial shape error is 27.9 nm, the roundness and flatness are 12.5 nm, and the machined surface roughness is less than 4.2 nm.

In order to maintain the machining accuracy, the temperature of the machine placed in the guardrail of the machine is accurately maintained at 20 degrees Celsius, the air temperature is controlled within the range of plus or minus 0.005 degrees Celsius, and the warm-up time is 1-2 days. At least after the machine is installed, The operation can only be started after twelve hours to dissipate the body temperature left by the mechanic. When cutting a part, all employees stayed outside the guardrail and took away a small amount of heat from the turning of the diamond with cutting oil held at 20 degrees Celsius. frame

The frame is made of a special grade alloy and one of the alloys with the lowest coefficient of thermal expansion of the metal. The anti-vibration system is equipped with four air isolation pads, two of which are connected internally and automatically balanced when subjected to force. In addition, there is a granite base. The granite has a low coefficient of thermal expansion, good stability, and the attenuation of vibration is 15 times stronger than that of steel. Constant temperature water flows by gravity to all parts of the machine; anti-vibration ditch, anti-vibration wall and separate foundation, the partition wall is double-layered, with sound-absorbing material in the middle, which can reduce the vibration of sound waves. Everything is done to ensure accuracy.

The parabolic mirror used by NASA is also produced by this cargo. Even more incredible is that you think this product is the latest high-tech product? In fact, the machine was developed in March 1980 and officially developed in 1984, sixteen years ago. It

The ultra-large-format CNC machining center that the former Guo Tailai and Professor Wang cooperated with, that is, the size of the processing over the guy, the machining accuracy is still slightly insufficient. Of course, Guo Tailai’s “manual” processing capacity has now reached 20 nanometers, which is definitely higher than this guy. "

If you work hard..." Guo Tailai thought for a moment: "I think we can be a little more precise than it. Of course, the operating system I am not good at. ”

"Which micro-feed system, online measurement system, vibration isolation system, temperature control system involved, can you solve this?" Professor Wang widened his eyes and stared at Guo Tailai, waiting for his answer.

"I am also a graduate of Fine Arts?" Guo Tailai laughed: "Well, temperature control needs to find helpers, but the rest are not the strengths of our fine instruments?"

What do you really want to do, and what is your doctorate? Professor Wang directly assured Guo Tailai: "Directly apply for the 863 Program, Professor Bo, I can't guarantee, Associate Professor, Master, I promise to get it for you." Whoever is not convinced, find me! ”

"I am not in school, I want to do what the associate professor said." Guo Tailai knew that Professor Wang was too excited and hurriedly refused: "I will not go out this time, I will do this."

After hearing the last sentence of Guo Tailai, Professor Wang and his second brother were speechless. Others do this, it is a scientific research, placed on Guo Tailai, is to do this play? But sometimes they really can't call this truth with Guo Tailai. It looks like the last large-format processing center. It seems that Guo Tailai is also involved in the mentality of playing.

Regardless of whether Guo Tailai is playing or scientific research, Professor Wang is a major challenge to his second brother. If this machine tool can be successfully developed, the ability to process ultra-high-precision optical lenses in China will be an indescribable leap.

At the thought of this, Professor Wang’s body began to tremble involuntarily, not cold, but excited.
