Chapter 476 Unable to Detect (Part 1)

The measurement accuracy of the optical flat-panel micrometer brought over was only 0.1 mm, which can be estimated to 0.01 mm. Originally, the technical management personnel did not take Guo Tailai seriously, so they did not bring particularly accurate measuring instruments.

In his opinion, no matter how advanced Guo Tailai's processing technology is for such a large flat panel, there will always be large deviations if the size exceeds a certain limit. Do not look at Japan and Germany can only make one meter two by one meter two? It's so big, you can basically measure the height difference by measuring the positions on both sides and the middle.

This time, the absolute plane of the large flat plate is to be a high-precision machining center. The design accuracy requires that the flatness can reach 2 microns, and the error that can be measured by even a flat plate micrometer is definitely unqualified.

That is to say, from the heart, the technical managers still feel that Guo Tailai is impossible to succeed. It is one thing to be able to make high-precision lathes and high-precision gyros, but it is another thing to be able to make large-area flat plates.

But now, the measuring tool he brought over couldn't measure 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 measured dozens of points on the two plates. It took a whole two hours, and there was no error in the measurement.

"Where's the measuring tool you use? What do you use? Does the laser interfere?" The technical management personnel were so shocked that they didn't know what to say, so they could only ask Guo Tailai: "Take your measuring tool Come out and I'm going to re-measure."

"I don't use any measuring tools." Guo Tailai smiled, spread his fingers apart, and pointed to his eyes: "This is my measuring tool."

"Visual inspection?" The technical manager was about to get angry: "Are you kidding me?"

If visual inspection can have this accuracy, what do so many measuring tool manufacturers do? Just because I once hindered Guo Tailai from making a large flat panel, so I am embarrassing myself here?

"Xiao Guo has always been visual inspection." Mr. Liu said slowly, explaining for Guo Tailai: "From the first time I met him, to the production of high-precision lathes and high-precision gyroscopes, all were visual inspections. Never used a measuring tool."

"It's the same for assembling machine tools for me." Professor Wang also smiled and said, "I don't even need a torque wrench, and the feel is absolutely accurate."

Zhao Xiangbei didn't speak at the side, but he knew what this technical manager did. Although it wasn't because of selfishness, the fat man made such a promise. He didn't trust this guy. You deserve it because you don't have the tools to measure it.

"Really?" The technical management personnel looked at Mr. Liu and Professor Wang suspiciously. Both of them nodded affirmatively, and Mr. Liu replied with a smile: "This is not seen by two people alone. Otherwise, why do you think everyone in our school supports Xiao Guo?"

"I need more sophisticated measuring tools." The technical management personnel also understood that it was a bit too much to deny Guo Tailai before, but they still said quickly.

"On the way here." Zhao Xiangbei said calmly. When his eyes turned to the two large plates, his eyes were also burning hot for a while. If the high-precision machining center can be realized this time, how easy will the group's processing and production be in the future?

Half an hour later, a batch of high-precision measuring tools from the Southern Group arrived. After some calibration and zeroing, the measurement quickly started.

An embarrassing thing happened. The most precise measuring instrument with the highest precision that can measure 1 micron, still failed to measure the large error of Guo Tailai's flatness. In short, the readings in all places were all All the same, it's flat.

Professor Wang has already begun to be extremely pleasantly surprised. The 1-micron gauge failed, and he was pretty satisfied. When he asked Mr. Liu to ask before, he asked whether the flatness of 1 micron could be achieved, but that was a size of 1.5 meters, and the design requirements were exaggerated. It is still the same flatness when it is enlarged to 3 meters. It is already accurate, isn’t it? Know how many times. From the looks of it now, it has exceeded its quota, and it has exceeded its quota by a lot. In other words, there is no need to worry about the absolute reference plane of the high-precision machining center he designed.

The creases on Old Liu's smiling face almost doubled in depth. In his lifetime, he saw such a large area of ​​absolute reference plane, and he can definitely rest in peace. With this reference plane, it is no longer a dream to manufacture machining centers with higher precision.

Everyone is happy, including the technical manager. He really had no selfish intentions, and he asked Guo Tailai to start with a small area out of prudence, but now that the large area has been realized, and it is still four times the size of the small area, and the accuracy is still so high, he has no reason to be unhappy!

The only thing that is a bit uncomfortable is that everyone doesn't know how high the flatness of Guo Tailai's work is. In other words, it cannot be marked. It is obviously inappropriate to mark 1 micron, but how much should be marked?

"I'm going to talk about 0.05 microns, and I don't think you will believe it." Facing this question, Guo Tailai said very speechlessly: "Then I won't talk about it, let's find a more precise measuring instrument to measure it!"

When he said this, whether it was Professor Wang, Mr. Liu, or Zhao Xiangbei, he immediately understood that this must have reached 0.05 microns.

But the problem is that the technical management personnel dare not follow Guo Tai's instructions at all! After all, he still doesn't have such complete trust in Guo Tailai. Although he has seen the finished product now, Guo Tai can't just say as much as he wants, right?

0.05 microns? How accurate is the best high-precision machining center in Japan and Germany? Handwork can be very precise, but it is impossible to reach that level, right?

"Then take your time and find a measuring instrument to measure!" Mr. Liu didn't care about it at all. Since he didn't believe it, he could find an instrument to measure it himself. Anyway, Zhao Xiangbei doesn't have any more accurate measuring instruments here. Let's see if it is possible to find more accurate instruments at the unit where the technical management personnel work.

But in any case, these two large-area reference planes must have exceeded the task, and everyone is happy. Now Professor Wang can safely and boldly go to the next step and start the next step of my country's highest precision CNC machining center. Of course, the urgent task at hand is how to transport the two large cast iron datum planes to the assembly center.

Because Guo Tailai didn't agree with Guo Tailai to go directly to the big tablet, Guo Tailai had no choice but to make it in this place instead of the assembly center with better conditions. Now, the technical management personnel have a headache, how can these two large plates with such precision be transported to the assembly center without damaging the precision.

"The processing of the spare parts will be left to you." When Professor Wang said this to Guo Tailai this time, no one objected. The only person who might object is still worrying about how to transport and even how to measure, what a headache!
