Siheyuan: I eat melons while doing scientific research

Chapter 1167 Three Axis or More (Three chapters today, one chapter will be released first)
For Bei Jiaozhi, this sea area is both a source of hope and a source of loss.

It is said that the source of hope mainly comes from the supplies and support coming from our side. Sea transportation is the most convenient and has the largest capacity. Moreover, some heavy equipment is much more convenient to transport by sea than by land.

Although we border them on land, sea transportation is more convenient.

Moreover, on the waterway from Beihai Bay to Beijiaozhi, there are islands where people can dock for supplies.

The source of the losses was that the air raids by the Citigroups were mostly from the sea, and this was more so the further north along the Jiaozhi terrain, the deeper into the dike. On the land, they had to pass through the air defense positions of northern Jiaozhi and deal with interceptions from aircraft coming from land airports, but on the sea, the former was almost non-existent and the latter was much less.

Therefore, the waters of the Beihai Bay have become a place of love and hate for Beijiaozhi.

The situation has changed, but the severity of the matter and the response strategy cannot be reflected immediately. The people in Beijiaozhi will only react after they feel the pain.

Beijing, Ministry of Foreign Trade.

A comrade hurriedly walked towards the leader of the Ministry of Foreign Trade with a document.

"Leader, here is an application for the import of special equipment. Please take a look."

The leader of the Ministry of Foreign Trade was a little surprised, because equipment imports generally did not need to be reported to him, otherwise, as the leader of a ministry, he would just approve these things every day and not want to do anything else.

"Oh? Let me see." The leader took the materials.

As if knowing the reason for his surprise, the comrade who came to report explained: "First, it is a bit expensive, second, it is rare, and third, it has a special source, from the 17th Ministry of Machinery."

The Seventeenth Ministry of Machine Building? The leader of the Ministry of Foreign Trade was startled, and immediately took out a pair of reading glasses from his pocket and looked at it carefully.

Application for import of high-resolution electron microscope

As soon as I saw the signature, it was the Third Rolling Mill, Third Branch of the Seventeenth Ministry of Machine Building.

No wonder the comrades below wanted to send it to me to read. It is related to Comrade Zhendong, so it is normal for them to attach importance to it.

When I opened the inner page, I saw that the applicant had indeed been signed by Gao Zhendong.

The leader of the Ministry of Foreign Trade did not read the contents carefully. He quickly took out a pen, signed his name in the application opinion section, and carefully wrote a few words.

"Agreed, do it quickly!"

He was too lazy to spend time reading the contents. The amount Gao Zhendong wanted seemed large at first glance, but compared with the money Gao Zhendong helped them earn, it was simply a drop in the bucket. Moreover, there must be a reason why Comrade Gao Zhendong wanted the equipment, and it was very important. Instead of spending time reading it, he might as well sign and buy it earlier. Maybe it would be more helpful to the work of the 17th Ministry of Machine Building.

However, Gao Zhendong did not buy this thing just for tearing tape, but it also plays a very important role in other things. For example, in metallurgy and testing samples during experiments, microscopes are a very important means, and optical microscopes seem to be unable to cope with the problem after the depth reaches 0.2 microns.

It can be said that if Gao Zhendong just wanted to tear off the tape, he probably wouldn't buy this thing specifically.

The head of the Ministry of Foreign Trade handed the application back: "Do it now, do it as soon as possible, and make sure it's done well!"

Gao Zhendong himself naturally didn't know such details. He was in his office listening to the comrades from the Third Factory report on their work.

"Chief Engineer Gao, this is the most sticky tape we have found. What should we do next?" Although they didn't know what Gao Zhendong was going to do, the comrades felt excited about participating in a major project.

However, Gao Zhendong's next words left them stunned.

"It's simple, just tear it for fun." Gao Zhendong said with a smile.

Hmm? These are the meanings.

They originally thought Gao Zhendong was joking, but they didn't expect that he was really tearing it for fun. It was not until Gao Zhendong found a piece of pyrolytic graphite sample and handed it to them, and then carefully taught them how to tear it and how to stick the two sides together and then tear it apart, that they realized that Chief Engineer Gao was not joking and was really tearing it like that.

I don’t know whether anyone has tried it or not, but I guess Chief Engineer Gao wouldn’t be that bored. But the specific operation is just to tear it open, stick a new one on, and then tear it open again.

The biggest reason why the anisotropy of pyrolytic graphite is so prominent is that its lamellar structure is very pure and the lamellar thickness is almost at the atomic level.

Judging from the anisotropy of thermal conductivity, it is almost certain that the pyrolytic graphite we have now meets the requirements for preparing graphene, so it is only natural to prepare graphene.

I still say the same thing, it doesn’t matter whether you give me the white skin or not, I have a bunch of them there anyway, and I won’t let you get them even if you don’t give them to me.

As for the application of graphene, anyone who wants to do it can do it. Judging from Gao Zhendong's experience in his previous life, it is still a long way to go before this thing can be applied.

This is actually very normal, just like many physical and chemical effects were discovered very early, but it took decades or even hundreds of years before they were applied.

A typical example is the laser gyroscope. "How do we know whether the requirements are met?" The comrades looked at Gao Zhendong blankly.

Gao Zhendong said: "There is no way to know whether it has met the requirements yet, but you can use a microscope to take a look and practice at the same time. As for the real test equipment, the import report has been submitted. When it is imported, you can complete this test thoroughly."

As for testing some physical and chemical properties of graphene, that can only be considered after graphene has been prepared.

With a lot of questions in their heads, the comrades from the Third Factory went back to the laboratory, scratching their heads and thinking, let’s just tear it apart.

After seeing them off, Gao Zhendong turned his attention back to modifying POSIL. This job had to be done quickly, and fortunately it was not difficult at all.

Not long after he sat down, another comrade from the Third Factory came to see him.

The leaders were from the Technical Department of the Third Factory and Yi Zhonghai.

As soon as he saw the two of them, Gao Zhendong knew that they were CNC machine tools!
"Chief Engineer Gao, after a long period of trial use of the CNC lathe, we feel it is almost ready now. However, our comrades suggested that we continue to develop another type of CNC machine tool, saying that only this type of machine tool can cope with most machine parts processing." A comrade from the Technical Department of the Third Branch Factory reported.

Yi Zhonghai saw Gao Zhendong looking up and was about to speak, but Gao Zhendong spoke first: "Milling machine, right?"

Yi Zhonghai was overjoyed. Hey, Zhendong is so amazing. He is just like a worm in the comrades' stomachs. Before the comrades even open their mouths, he already knows what they are going to do.

CNC lathes and milling machines, these two things together can handle most parts processing.

However, unlike a lathe which has two axes, there are many things to say about a milling machine.

"Yes, yes, that's right. The types of parts that can be processed by lathes are limited. If you add a milling machine, then most machining processes can be said to be covered. As for other planers and the like, those don't matter. It doesn't matter if you don't have them for now."

Gao Zhendong nodded: "Well, your consideration is correct. Are you sure?"

The Technical Department and Yi Zhonghai both nodded vigorously: "Chief Engineer Gao, we have discussed it and it is no problem. With our experience with CNC lathes, we believe that this milling machine will be faster than a lathe."

Although the movement and feeding forms of the workpiece and props are somewhat different, they are all within the scope of electromechanical. The experience on the lathe is very meaningful for the milling machine, so the comrades are very confident.

Different from the previous time when we were stumbling around and lacking this and that, and needed Chief Engineer Gao to constantly provide help in terms of technology, spare parts, materials, etc., this time when we were making the milling machine, the conditions were much more mature, and many spare parts and experience on the car windows could be transferred over.

Comrades are very confident, Gao Zhendong is also very happy, it’s good that you have confidence!
Gao Zhendong smiled and said, "Well, let me make it a little more difficult for you."

Comrades are a little nervous. Will it be difficult? Chief Engineer Gao said it will be difficult, so it may really be difficult.

But then I thought, what was easy to make with Chief Engineer Gao? But what was not made?

Since he said that, I think he has an idea in mind.

Besides, being cowardly before a battle is not what we worker comrades should be like.

"No problem! Mr. Gao, please give the task!" The comrade from the Technical Department said with a smile, although he was still a little nervous.

Gao Zhendong nodded: "Okay, I ask that if you want to do it, you should do three axes or more. Two axes or two and a half axes are meaningless."

Upon hearing this, the comrades felt relieved and thought, this is not bad.

They estimated that it was hard to say whether it would have four or five axes, but three axes should be no problem, or they had wanted to lean towards three axes from the beginning, and now that Gao Zhendong had given them the task, it would be even better.

Since Chief Engineer Gao has given the task, it means that he will definitely provide support that matches three axes or more.

Everyone knows that Chief Engineer Gao does not have the habit of sending hungry soldiers. If he wants to get things done, he must provide support. Moreover, this support is not only for the work itself, but also for the individuals involved.

"Okay, Mr. Gao, let's sign a military order!" The comrades working on machine tools were full of fighting spirit.

Gao Zhendong laughed and said, "Then go and prepare. Submit your plan and I'll sign it for you. Oh, and prepare to inspect the lathe first. This is a lathe that can be designed and directly processed with our latest industrial design software, which is equally important."

Several comrades looked at each other, and the comrade from the Technical Department said, "Chief Engineer Gao, can we wait for the milling machine to come out so that we can test it together? We can also put a big one, hehe. And if we want it to work well with the latest industrial design software, it still needs a milling machine."

Gao Zhendong was stunned. He didn't expect that his comrades were so ambitious.

He thought about it and did not discourage his comrades: "Are you sure you can do it in a short time?"

"Yes! We have confidence!" The comrades were full of confidence. Gao Zhendong estimated that they might have considered it carefully before coming to him.
