~： The second hundred thirty-seven, another one was shocked (on)

"I? Exaggerated?" Guo Tailai pointed at his nose and looked like he hadn’t played this yet? Why was it a buckled hat?

"Sorry, the wording is not appropriate." The technical management staff sincerely apologized: "I just think that we should proceed step by step, start with small, accumulate experience, and then grow bigger step by step. This is not a failure, it will not be too Big loss. Don't step too big, lest the horse lose its forefoot."

From a prudent point of view, there is nothing wrong with the technical management staff. Others are not bad. I have always said that it has always been a technical problem. There is no other private goods. I have no selfishness. This should be affirmative. The only problem is that he is not confident enough about Guo Tailai. "

I can do it. Guo Tailai once again expressed his confidence: "Please believe me." ""

Too risky. "Although there is almost all the support of the school, but the technical management staff still shakes their heads: "Once the failure, the loss is not small, it is more appropriate. ""

This, I am taking the liberty. Guo Tailai felt that he should still be able to fight for it. He quickly asked: "If it is a failure, it is my personal working hours plus a large area of ​​cast iron board. I have not even said that I have to pay wages. How much loss can I have?" "This

It is to give the country a project for the school. After it is made, it will bring about a huge take-off of the entire domestic CNC machine tool. Guo Tailai is supported by both hands and feet. This matter, Professor Wang said that Guo Tailai did not ask for salary or anything. He originally intended to give free gifts. This can also be counted as a major loss, and Guo Tailai can never admit it. Guo

The words of Tailai made the technical management staff frowned deeply, and even looked at the leadership of Professor Wang and the fine instrument with a trace of suspicion. Where did you find the hoe? Don’t you pay for it without losing money?

"Sorry, I don't know if you really understand the absolute plane production process." The technical management staff saw no one to talk, and 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 thing that comes with the loss of three tablets is not one."

In the production of absolute planes, it is generally the experienced master who uses a blade to level the roughed plane and shovel a contrast plane. Color is applied to the control plane, and the processing plane is slid on the control plane. The portion of the processing plane that is stained with the color and the portion of the control plane that is out of color are the portions that are higher on the two planes. Shovel the raised part and continue to slide. This process is repeated cyclically until the colors of the two planes are completely uniform.

However, the plane that is created is not an absolute plane. In order to prevent the two sides from forming the same curvature, the same effect can be achieved, so another reference plane is needed. Usually when machining an absolute plane, you need to machine three planes at the same time. Only when any two of the three planes are consistent, the absolute plane is considered.

This is what technical managers say. Three planes at a time, broken is definitely not just a bad one, but three.

“In addition, the roughing of small-area planes, although we don’t have a grinding machine of that size at present, it’s not a special investment in the transformation.” The technical management staff said slyly: “But if you change to a large-area grinding machine, then change There is more, although it is only a roughing grinder, the huge area change brings about qualitative change. It takes a long time to invest."

"More, the larger the area, the greater the weight, and the greater the deformation of the flat plate." The technical management staff still made some thoughts, saying that the words are heavy: "In order to double-grind, it must be lifted several times. Inevitably, the precision is reduced. Unless a large double-plate grinding machine is specially developed for this purpose, it involves a lot of capital and time investment."

"Xiao Guo, I am not targeting you." The technical management staff did not think of anything else, but from the perspective of practical operation: "But it is a three-meter by three-meter board, the risk is too big. Or start from a small, Come step by step!"

From the perspective of normal manufacturing, this technical manager is very reasonable. It is also in line with the gradual development of thinking, experience is accumulated from the success or failure of time and again, but also must be accumulated from the process of possible realization. If you come up with a big rocket and know that it is impossible, then you can accumulate any experience. Apart from the lesson, there will be nothing else.

From the perspective of Guo Tailai, the things he is worried about will not happen at all! Guo Tailai will certainly not use three planes to cross-reference each other to make an absolute plane. His current measurement accuracy can reach 5 nanometers, and the processing precision is 50 nanometers, which is higher than the processing precision in the chip. As long as you can visually measure which block is high on the plane and the error is not more than 50 nanometers, it is basically impossible to fail. Even if it fails, it is really a loss of a cast iron plate. ask

The question is that Guo Tailai’s own processing methods cannot be said! At least I can't say it completely. He can say that he has a high processing precision. He can say that he is unique in his own hands. He can say that his processing time is short and fast. He can do things with nano-robots. He can't say a word.

This has become a contradiction. The technical management personnel here did not dare to completely trust Guo Tailai's technology, for fear that it would delay the project and bring losses. On the other hand, Guo Tailai could not prove his technical strength, so the two sides had differences.

"If you don't, I only need two pieces of cast iron plates that release good stress." Guo Tailai couldn't help the technical management staff at once, but he could only come up with his own way of dealing with the employees: "Give me a week, I will do two of you." Take a look at it. During this period, the preparations for the work can be continued, without delay, how?"

The people of the school must have supported Guo Tailai from top to bottom. Now the technical management staff of the ministry is relatively cautious. Can't say that people's things are not done right, he thinks about it and he thinks so. Guo Tailai said that it was already a good face. Professor Wang and the department leaders did not say anything and immediately supported it.

Relatively speaking, this is barely acceptable. Not delaying the preparation work, at most two cast iron plates and a week's time, and the time can not be counted, the technical management staff finally nodded after weighing the balance.
