Chapter 237: Another one who was shocked (below)

Can get this result, Guo Tailai is also relatively satisfied with a little bit.
Can't blame others for not believing in their abilities, because Guo Tailai has never shown such ability before. This is different from Professor Liu Laowang who treats Guo Tailai. Liu Lao knows that Guo Tailai has this skill. Professor Wang also knows that Guo Tailai has done more and more high-precision lathe craftsmanship, but the technical management personnel do not know. where
I am afraid that others have told him that Guo Tailai had done this before and had done high-precision gyro, but he still feels cautious. There is no mistake in step-by-step promotion. In fact, this is also the idea of ​​most people who know this project. It really supports Guo Tailai, and there are only a few people in the school. This
As for the sample, Guo Tailai does not need to shovel out the absolute plane under the eyes of everyone, and find a place to do it. Do not
However, the choice of this address is not an easy task. Guo Tailai wants to achieve the accuracy of 50 nanometers, and has to consider the environment of constant temperature and vibration. This is not the same as making woven ball shades and making chips for those in the company.
Weaving the ball shade, there is no drawing, this fiber is slightly biased, and the angle of the winding has changed somewhat, and no one can see it. The chip is even more so, the two transistors are close to each other, and the other two are farther away. Who will measure so accurately? can
Absolute planes are different. Guo Tailai wants to have a flatness of no more than 50 nanometers, and to do such a large area, some things have to be considered. A few degrees of temperature change, I am afraid that the height difference on the unfinished plate will exceed 50 nanometers. Gravity effects should also be considered. This is the basis for high-precision absolute planes, which is the basis of the CNC machining center. If the accuracy is wrong, the absolute accuracy of the machining center will be affected, and it will be affected by the amplification. There is a problem with the benchmark, and the processed workpieces must be accurate.
Needless to say, although the impact of the vibration of the thick cast iron plate is not too great, Guo Tailai is the ultimate pursuit of this guy, he is looking forward to the ultimate product. A little bit of Guo Tailai is uncomfortable, especially this time to pursue the limit of 50 nanometer flatness, Guo Tailai should minimize the influencing factors. Place
Before returning abroad, Guo Tailai and Zhao Xiangbei called and asked him to find a suitable place, constant temperature and humidity, the land should be strong enough, and it would be better to level it up and strengthen it. The other one is to do anti-vibration treatment.
Zhao Xiangbei did not think that Guo Tailai had a big problem. He knew what Guo Tailai had to do and was very supportive. He seriously helped Guo Tailai find a suitable place. There is no road around the island in a lake in the suburbs of Beijing. The vibration of the subway will not be affected. Constant temperature treatment, clean up, just wait for Guo Tai to work.
The room passed Huang Weiguo's inspection, there is no problem, the lighting is also the choice of the operating room level of large-scale shadowless lights, the lights are bright and soft, not dazzling. The temperature is constant at twenty degrees Celsius and the error is plus or minus one degree. The ground is specially reinforced, and a cast iron slab is placed and will not see changes.
The work space is large enough to allow the specially designed forklift to be lifted from the four directions smoothly with the lifting device above, without the impact of gravity. Moreover, the cast iron slab is not exactly three meters by three meters in size, but three meters five by three meters five, and the edge part is considered to be more likely to be transported. In short, all the influencing factors have taken into account the extreme. Light
It took a whole day to pull the cast iron plate to this side. The two countertops were placed flat in a short distance, waiting for Guo Tai to work.
Guo Tailai rushed everyone out, locked the door of the workplace, let Huang Weiguo stare at them, no one should interfere with him, and then the guy started to work. for
Not only because his weight standing on the big board affects the accuracy, Guo Tailai even built a movable workbench that can be fixed and can be fixed on the workbench, which is five centimeters higher than the large plate. The position of the center of the board.
Cast iron slabs have been roughed, but because the plates are too large, the precision of the machining is not particularly high, and the accuracy can be as much as one tenth of a millimeter. Guo Tailai started from the edge, all the nano-robots went up and started to make absolute planes little by little.
The accuracy of this requirement is too high. Guo Tailai even fears that his body is in contact with the slab so that the body temperature changes the size of the plane. He is separated by a centimeter or so, just like the apron of cast iron slab.
Each time a size of ten centimeters by ten centimeters is machined, Guo Tailai will process the iron chips that have been cut above to make an illusion of scraping, and then blow it down with air, and the hand does not touch the large board at all. Even when it was processed in the middle of the big board, Guo Tailai was directly on the movable workbench and handled it little by little. It is completely out of contact with cast iron slabs. whole
For the entire five days, Guo Tailai did not leave the workplace except eating and going to the bathroom. Even sleeping was inside. For the best precision, Guo Tailai can say that he is always focused on the spirit. Within five days, Guo Tailai has lost 20 pounds, and everyone can imagine how hard he has paid for it.
However, looking at the two pieces of scraping pattern is very neat, flatness of not more than 50 nanometers of three meters by five to three meters of cast iron slabs, Guo Tailai still showed a happy smile on his face. Finally finished!
Guo Tailai gave Mr. Wang a call to Liu Lao to Zhao Xiangbei and asked them to come over and test. The rest of the trouble, I am afraid that it will be shipped to the right place, but that is not what Guo Tailai has to worry about, his work has been done.
Less than an hour after the phone call, Professor Wang Lao and Zhao Xiangbei came one after another. The technical management staff of the same company, but Guo Tailai did not have his phone call, Professor Wang informed him to come over and check the acceptance. very
Obviously, the technical management staff is still a bit surprised, but think about it is two cast iron slabs, but also lost, so did not say anything. But when he got here, he saw the layout of the work room and his face changed. I am afraid that there will not be hundreds of thousands of this work room, and it will not be arranged at all. If Guo Tailai fails the test, I am afraid that the loss will be gone. "
Pretty! "The tension with the technical management staff is completely different. Liu Lao looked at the evenly scratching lines on his face. The smile on his face was praised sincerely."

How is it possible?
When the technical manager used the optical flat micrometer to detect several points, no errors were found, and the technical management staff screamed on the spot.
