The optical flat micrometer he brought with him only had a measurement accuracy of 0.1 mm and could be estimated to be 0.01 mm. Originally, Technical managers didn't think much of Guo Tailai Lai, so he didn't bring any particularly accurate measuring equipment.
In his opinion, there was always a big discrepancy for such a large plate, no matter how skilled he was in manufacturing it, if the size exceeded a certain limit. If you don't look at Japan, Germany can only do 1.2 times 1.2 meters? At this size, if you measured the height difference between the two sides of the bridge and the middle part of the wall, you would be able to determine the height difference.This time, the large flat plane had to have a high precision processing center. The design precision required the flat plane to be 2 microns, and even the micrometer's error could be measured, so it was definitely not qualified.
In other words, from the bottom of his heart, Technical managers still felt that Guo Tai Lai would not succeed. Being able to produce high precision lathe s was one thing, but being able to produce large scale tablets was another.
But now, the measuring tool he brought here could not detect any errors. What did this mean? This indicated that Guo's processing level was much higher than that of the plate micrometer.
Technical managers did not believe it. He tested each of the stone tablets on dozens of points. Even after spending two hours, he still could not find any errors."What about the measuring tool you used? What did he use? Laser interference? " Technical managers was so shocked that he did not know what to say. He could only beg Guo Tailai, "Take out your measuring tool, I want to measure it again."
"I don't use any measuring tool." Guo Tai Lai laughed, his two fingers pointed at his own eyes, "This is my measuring tool."
"A visual estimation?" Technical managers was already angry: "Are you joking?"
If one could see the accuracy of this technique, then what was the use of so many measuring tool manufacturers? Was he trying to embarrass himself here because he had once prevented Guo from making a big flat plate?
"Xiao Guo has always been a visual observer." Elder Liu opened his mouth slowly, explaining for Guo Tailai: "From the first time I saw him, to the production of high precision lathe, to the production of high precision gyroscope, it's all visual estimation, I've never used a measuring tool."
"Same goes for the machine tools on my side." Professor Wang also laughed as he continued, "You don't even use the torque wrench, your touch is absolutely accurate."
Zhao Xiangbei stood at the side silently. He knew what this Technical managers had done, although it was not out of selfishness, but since Fatty was so sure, this fellow did not trust him."Really?" Technical managers looked at Elder Liu and Professor Wang in doubt. The two of them nodded with certainty, and Elder Liu laughed even more as he replied: "It's not something that can be seen by just one or two people. Otherwise, why do you think that everyone in our school supports Xiao Guo?"
"I need more precise measuring tool." Technical managers also understood that it was too much to reject Guo Tai Lai like that, but he still replied quickly."On the way." Zhao Xiangbei said calmly. When he looked at the two flat plates, his eyes burned with passion. If he could really achieve a high precision processing center this time, how easy would it be for the corporation's production in the future?
Half an hour later, a group of high accuracy measuring tool from the South Group arrived. After returning to zero, he quickly started the measurement.Embarrassment happened. Even with the highest precision, which could measure a micron meter, he still could not measure the error of Guo Tailai's plane. In short, the readings were the same everywhere, it was completely flat.
Professor Wang was already very happy. He was already quite satisfied that he could not measure it with a micrometer. Previously, when he had asked Elder Liu, he had asked him if he could achieve a 1 micron plane degree, but that was only 1.5 micron. Furthermore, it had exaggerated the design requirements by enlarging it to 3 meters or even this plane degree, which was already several times more precise. From the looks of it, he had overdone it, and even overdone it a lot. In other words, he already didn't need to worry about the absolute benchmark plane of processing center that he designed.
Elder Liu smiled so much that the wrinkles on his face nearly doubled. In his lifetime, when he saw such a large area of absolute reference plane, he would definitely be able to rest in peace. With this benchmark level, going further and further into processing center to make more accurate copies was no longer a dream.
Everyone was very happy, including the Technical managers. He really didn't have any selfish motives. He made Guo Tailai start from a small area, but now that it was a big area with four times the small area, and the accuracy was so high, he had no reason to be unhappy!
The only thing they were not happy about was how flat Guo Tailai was this time. They didn't know. In other words, it couldn't be marked. A scale of 1 micron was obviously inappropriate, but how much should it be?
"If I said 0.05 μm, I'm afraid you wouldn't believe me either." Guo Tailai faced this question and said speechlessly, "Then I won't say anymore, let's find a more precise measuring instrument!"
As he said this, be it Professor Wang, Elder Liu, or Zhao Xiangbei, they all immediately understood that this must have reached 0.05 μm.But the problem was that he did not dare to follow Guo Tailai's instructions at all! He still didn't trust Guo Tailai that much. Although he had seen the finished product, he couldn't say how much was enough for him.
0.05 μm? How accurate is the best precision processing center in Japan? Although it was possible to do it by hand with great precision, there was no way it could have reached such a level, right?
"Then you should slowly search for a measuring instrument!" Elder Liu didn't care about this at all. Since he didn't believe it, he would look for the apparatus to test it himself. Zhao Xiangbei didn't have a more accurate measuring instrument here anyways, and wanted to see whether or not he could find a more accurate one when he was at Technical managers's side.
But in any case, these two large reference planes must have been overdone, and both were overjoyed. Now, the Professor Wang can confidently take the next step and begin the next step of the most accurate job in our country, the NC Machining Center. The immediate priority, of course, was to get these two large areas of cast iron reference planes to the assembly center.Since he didn't want Guo to go directly on the tablet, he couldn't only make it here, not in a better assembly center. Right now, it was Technical managers's turn to have a headache. How could he transport these two giant tablets, which were so precise, to the Assembly Center without damaging their accuracy?
"I'll leave the rest of the parts processing up to you." When Professor Wang faced Guo Tailai and said that, no one objected. The only person who might object was still worrying about how to transport the ship, or even how to measure it.
