Chapter 238: Can't measure it (on)

The optical flatmeter with the measurement accuracy of only 0.1 mm can be estimated to be 0.01 mm. The technical management personnel did not take Guo Tailai seriously, so they did not have a particularly accurate measuring instrument. in
He seems that such a large flat plate, Guo Tailai's processing technology is higher, the size can exceed a certain limit, there will always be a large deviation. Can you only do one meter two by one meter two without looking at Japan and Germany? So large, the position of the two sides and the middle of the test, basically can detect the height difference. This
The secondary flat absolute plane is to be a high-precision machining center. The design accuracy is required to achieve a flatness of 2 micrometers. The error that can be measured even with a flat micrometer is definitely unqualified. and also
That is to say, from the inside, technical managers still feel that Guo Tailai is unlikely to succeed. It is one thing to be able to make high-precision lathes and high-precision gyros, but it is another thing to make large-area slabs. can
Now, the measurement tools he brought with him can't detect the error. What does this mean? It shows that Guo Tailai's processing level is much higher than the measurement accuracy of this flat micrometer.
The technical management personnel did not believe in evil, and they measured it on dozens of points on the two plates. It took two hours and did not measure a little error. "
What is your own measurement tool? What is used? Laser interference? "Technical managers have been shocked to not know what to say, only to ask Guo Tailai: "Get your measurement tools out, I have to re-measure."

"I didn't use any measurement tools." Guo Tailai smiled, his fingers crossed and pointed at his eyes: "This is my measurement tool."

Visual inspection?
The technical manager is already angry:
What a joke?

If there is such an accuracy in visual inspection, what more do the measurement tool manufacturers do? Just because I once blocked Guo Tai to make a large flat plane, is it embarrassing here? "
Xiao Guo has always been a visual test. Liu Lao slowly opened his mouth and explained it to Guo Tailai: "From the first time I saw him, to the production of high-precision lathes, the production of high-precision gyros, all visual inspection, never used measurement tools." ""
It is also the assembly machine for me. Professor Wang also smiled at the interface: "No torque wrench is used, and the feel is absolutely accurate." Zhao
He didn't talk to the north. He knew what the technical management staff had done. Although it was not because of selfishness, the fat man was so guaranteed. This guy didn't trust it. You should have no tools to measure.

Really?
The technical management staff looked at Liu Lao and Professor Wang with suspicion. Both of them nodded affirmatively. Liu Lao replied with a smile: "This is not what one person sees. Otherwise, do you think that everyone in our school supports Xiao Guo because of what?"
"I need more sophisticated measurement tools." The technical management staff also understood that Guo Tailai was a bit too much before, but he said quickly. "
On the way to the transport. Zhao Xiangbei said calmly. When the eyes turned to two large flat plates, the eyes were also a bit of burning. This time, if the high-precision machining center can be realized, how easy will the group's processing and production be in the future?
Half an hour later, a group of high-precision measuring tools from the Southern Group came over. After some calibration was zeroed, the measurement started quickly.尴
The embarrassing thing has appeared. The most accurate and accurate measurement that can be taken this time can measure the 1 micron measuring instrument. It still can't measure the error of Guo Tailai's flatness. In short, the readings are everywhere. Again, this is flat.
Professor Wang has already begun to surprise. The 1 micron meter failed to measure it, and he was quite satisfied. Before he asked Liu Lao to ask, could he ask whether he could achieve a flatness of 1 micron, but it was a size of one meter and five, and it still exaggerated the design requirements, magnified to three meters or this flatness, it has been accurate. I know how many times. It seems that this is over-completion, and it has been overfulfilled. In other words, he has no need to worry about the absolute reference plane of the high-precision machining center he designed. Liu
The pleats on the old laughing face are almost twice as deep. In his lifetime, he saw such a large area of ​​absolute reference plane, which is absolutely remarkable. It is no longer a dream to have this reference plane and to make machining centers with higher precision. Place
Someone is very happy, including the technical manager. He did not have selfishness. For the sake of prudence, Guo Tailai started from a small area, but now it has been realized in a large area, and it is still four times smaller than the small area. The accuracy is still so high. He has no reason to be unhappy!
The only thing that is a bit uncomfortable is how high the degree of flatness that Guo Tailai made this time. Now everyone doesn't know. In other words, it cannot be labeled. The standard is 1 micron, which is obviously inappropriate. How much should it be marked? "
I have to say 0.05 micron, I don't think you believe it. Guo Tailai faced this problem and said very silently: "Then I will not say it, look for more sophisticated measuring instruments!"

He said this, Professor Wang, Liu Lao, Zhao Xiangbei, immediately understand that this must be 0.05 microns. but
The problem is that the technical management staff did not dare to follow the instructions of Guo Tai! He did not have such complete trust in Guo Tailai. After all, he has already seen the finished product, but can't it be how much Guotai said? 0
. 05 micron? How accurate is the best high-precision machining center in Japan and Germany? Manual can be very precise, but it is impossible to go to that point?
"Then you slowly find a measuring instrument to measure it!" Liu Lao did not care about it. Since he did not believe it, he would look for an instrument to measure it. Anyway, Zhao Xiangbei has no more accurate measuring instruments here. It is impossible to find more accurate instruments on the side of the technical management personnel.
But in any case, these two large-area reference planes are definitely over-completion tasks, and they are all happy. Now Professor Wang can safely go to the next step and start the next step of the most high-precision CNC machining center in China. Of course, the immediate priority is how to transport these two large-area cast iron reference planes to the assembly center. because
Before I disagreed with Guo Tailai directly on the big flat plate, Guo Tailai couldn't make it in this place, not a better assembly center. Now, the technical management staff has a headache. These two large plates that are accurate to this point can be transported to the assembly center without damaging the accuracy. "
The processing of the next spare parts is handed over to you. "When Professor Wang Tailai said this sentence again, no one has objected. The only person who might oppose it is still worried about how to transport it, and even how to measure it, headache!
