Chapter 474: Another Shocked One (Part 1)

"Me? Exaggerated style?" Guo Tailai pointed at his nose and was stunned. It seems that he hasn't played like this before, right? How could he be labeled as flamboyant?

"Sorry, the wording is inappropriate." The technical management staff apologized sincerely: "I just think that we should proceed step by step, start small, accumulate experience, and then expand step by step. Even if it fails, it will not be too big. Big loss. Don't take too long a step, lest you stumble."

From a cautious point of view, there is nothing wrong with the words of technical managers. Others are not bad, and what I said before was always a technical problem. There is no other private goods mixed in, and I have no selfish intentions. This should be certain. The only problem is probably that he lacks confidence in Guo Tailai.

"I can do it." Guo Tailai said again confidently: "Please believe me."

"It's too risky." Despite the support of almost everyone in the school, the technical managers still shook their heads: "Once it fails, it will bring a lot of losses. It is more appropriate to proceed step by step."

"Well, forgive me." Guo Tailai felt that he should still be able to fight for it, and hurriedly asked: "If it really fails, it's just my personal working hours plus a large cast iron plate. I didn't even ask for salary. How much loss is there?"

This is a project for the country to do for the school, and after it is completed, it will bring about a substantial take-off of the entire domestic CNC machine tool. Guo Tailai supports it with both hands and feet. When Professor Wang mentioned this matter, Guo Tailai didn't even ask about the salary. He was supposed to donate for free. This can also be regarded as a major loss, Guo Tailai will never admit it.

Guo Tailai's words made the technical managers frowned deeply, and even looked suspiciously at Professor Wang and the leaders of the Department of Precision Instruments. Where did you find Lengtouqing? Wouldn't it bring losses if I don't want wages?

"Sorry, I don't know if you really understand the production process of the absolute plane." Seeing that no one spoke, the technical management staff finally frowned and said: "First of all, the processing of the absolute plane is not one piece at a time, but three pieces at a time. So, if you fail, the first loss is three slabs, not one.”

In the production of absolute planes, experienced master craftsmen usually level the rough-machined planes one by one with a spatula, and at the same time shovel out a comparison plane. Paint the color on the comparison plane, slide the processing plane on the comparison plane, the part stained with color on the processing plane and the part that loses color on the comparison plane are respectively the parts that are higher on the two planes. Flatten the raised part and continue sliding. This process is repeated and repeated until the colors of the two planes are completely uniform.

However, the plane produced in this way is not an absolute plane. In order to prevent the two surfaces from forming the same arc to achieve the same effect, another reference plane is needed. Usually, when processing an absolute plane, three planes need to be processed at the same time, and only when any two of the three planes are consistent can the absolute plane be considered.

That's what technical managers are saying. Three planes at a time, if it is broken, not only one piece is broken, but three pieces.

"In addition, for the rough machining of small-area planes, although we don't have a grinder of that size at present, it does not require a large investment in transformation." The technical management staff talked eloquently: "But if it is replaced by a large-area grinder, then the change There are many, although it is only a roughing grinder, the huge area change brings about a qualitative change. Not to mention the large investment, it will take a very long time."

"Moreover, the larger the area, the greater the weight, and the greater the deformation of the plate." The technical management staff still thought about it, and said earnestly: "In order to grind both sides, it must be lifted many times. It will inevitably lead to a reduction in precision. Unless a large-scale double-plate grinding machine is specially developed for this purpose, this involves a large amount of capital and time investment.”

"Xiao Guo, I'm not targeting you." The technical management personnel really didn't think about anything else, but from the perspective of practical operation: "But getting started is a three-meter-by-three-meter board, and the risk is too great. It's better to start small, Come step by step!"

From the perspective of normal processing and manufacturing, what the technical manager said is very reasonable. And it also conforms to the step-by-step development thinking, experience is accumulated from success or failure again and again, and it has to be accumulated from the process of possible realization. If you just launch a big rocket when you come up, knowing that it is impossible to do it, then what kind of experience can you accumulate? There will be nothing but lessons.

But from Guo Tailai's point of view, what he was worried about would never happen! Guo Tailai will definitely not use three planes to refer to each other to make an absolute plane. His current 360-degree 3D measurement accuracy can reach 5 nanometers, and the processing accuracy is 50 nanometers, which is higher than the processing accuracy in the chip. As long as you use visual inspection to measure which piece is higher and which one is lower on the plane, and the error will not exceed 50 nanometers, not to mention that it is basically impossible to fail, even if it fails, it is really just a loss of a cast iron plate.

The problem is that Guo Tailai's own processing methods can't be said! At least he can't say it completely. He can say that he has a high processing precision, that he has unique handwork, and that he has a short processing time and fast speed, but he can't say a word about nano-robots.

This becomes a point of contradiction. The technical managers here did not dare to fully trust Guo Tailai's technology, for fear of delaying the project and causing losses. On the other hand, Guo Tailai could not prove his technical strength, so the two sides had differences.

"Otherwise, I just need two cast iron plates that have released the stress." Guo Tailai had no way to convince the technical management staff at once, so he could only come up with his own way to deal with the employees: "Give me a week, and I will make two of you. Measure it. During this period, the preparations that should be done can continue to be done without delay, how about it?"

The people in the school must have supported Guo Tailai from top to bottom, and now the technical management personnel of the ministries and commissions are relatively cautious. It can't be said that other people's affairs are not done right, and there is a reason for him to think so. What Guo Tailai said was enough to save face, and Professor Wang and the department leaders immediately supported it without saying a word.

Relatively speaking, this is barely acceptable. Without delaying the preparation work, it would take at most two cast iron plates and a week's time, and the time could not be counted at all. After weighing it, the technical management staff finally nodded.
