Start a blacksmith shop

Chapter 129 Discovering Problems and Engines
"Okay, that's it, the company is still expanding,

Money is needed everywhere, and this money is already very good! "

Liu Xiaodong and the two later agreed to the dividend plan, and together they made a plan for the company's development next year.

After talking about the work, the rest is to eat and drink, two lambs, more than one was eaten by them.

After eating and drinking, they went back to their respective homes. Li Zhenhua and Li Yun went back to the hotel.

"Let's go home with me to celebrate the New Year this year!" The two of them nestled on the sofa, and a TV series was playing, but neither of them focused on the TV.

Hearing Li Yun's question, he also fell into silence, and waited for a while before answering her question.

"I won't go to Haicheng this year. I'll just stay in the blacksmith shop. At that time, the people who built the houses behind will also leave, and the house will not be noisy. I will go back and live directly.
I also lived in Haicheng last year, and some customs were not followed. This year is not good, the family hall still has to be enshrined, and I have to go to the grave of my grandfather and parents in the second year of junior high school. There are so many things! "

After Li Zhenhua finished speaking, Li Yun did not force him to go to Haicheng, she also had her own thoughts in her heart.

As the year approached, the company's affairs got busier, but none of this had much to do with him.

It has no effect on him, and he still maintains the previous rhythm of life!
At the end of the year 26, Li Yun went home, and after she left, he moved back to the blacksmith shop.

When he was left alone at home, he felt more free. As the Chinese New Year approached, he no longer planned to go to the company anymore.

This time is just right for him to get into the virtual laboratory and do his own research.

In the laboratory, with the precision of fifty nanometers, the existing chips are optimized with the help of analytical eyes.

In his hands, the lithography knife also played a very important role, but as more and more chip circuit diagrams were drawn,
He gradually developed a sense of disgust for this repetitive work in his heart, but when he turned his attention back to the lithography knife in his hand,
He was immediately stunned, as if he had entered a misunderstanding, why did he have to carve by hand?
What is the difference between humans and animals?People can use tools, but animals can't,
Why doesn't he upgrade the lithography machine from 1 micron to 0.05 micron?
A feeling of being stupid and wasting a lot of time came over me.Then he studied the lithography machine.

Erase half of the things in front of me in the laboratory, and then re-embody the micron-scale lithography machine I bought.

Looking at the original lithography machine that reappeared in front of me, I felt that a lot of time was wasted.

There are shortcuts that I did not take, but chose the most difficult path.

And just as his understanding of lithography machines and chip manufacturing got deeper and deeper, he gradually felt his ignorance.

There is a truth, the more knowledge you know, the more you will feel ignorant, because when you don’t understand, you will feel that one thing is easy to do,
But with the gradual increase in knowledge, I also understand how difficult it is to do.

I suddenly felt that I was really lucky to be able to make the chip before. This is only in the virtual laboratory, so I was able to make it.
If this is true in reality, let alone rubbing a chip out of his hands, a clean room alone will be difficult for him.

It was also after having these ideas that he gradually lost confidence in the idea of ​​rubbing chips.

If it is to rub out the chip in reality, it will be a huge project. The first thing to do is to build a clean room with a grade of [-].

There is still a lot to do in reality, but with their current size, they simply don't have that much money to build these things.

Since then, he has completely abandoned the idea of ​​rubbing chips by hand, because it is impossible to achieve in the current reality.

It seems that in the virtual laboratory before, everything I did was useless,
But this also made him realize what the chip industry is. Among the things he learned, there is still a long way to go in Kyushu.

Lying on the bed, he opened his eyes again, looked at the dark room, sighed, turned over and fell asleep.

However, after Li Yun returned to Haicheng, she faced pressure from her parents, thinking that she came back alone, and did not bring Li Zhenhua back.

Ding Yan once thought that the two of them had broken up, but she also knew the reason after cross-examination.

Although the two of them are not married yet, in Ding Yan's eyes, the relationship between the two can be said to be a certainty.

After understanding the reason, Li Yun was let go.

During the Spring Festival, people also have free time. A large number of people are watching dramas at home and using Douyin.

At this time, the video of the Antarctic team, which can be called a movie-like plot, became popular.

The reason for the fire is also very simple. This time it became popular, it started from the external network.
A scientific expedition team of Michiko in the Antarctic team encountered the same situation as the Kyushu Antarctic team when they went out to do scientific research.

The same ice surface was broken, but their snowmobiles did not play much role,
There were six snowmobiles in total, but only two got out in the end.

The remaining four vehicles and the four people in the vehicle were all buried in Antarctica facing the broken ice.

After the only two people left ran back to the scientific research station, they reported the matter to them.
The video as evidence was also submitted to the above, and one of the staff members also uploaded these videos to the Internet.

An exchange student in a bad country in Kyushu, after seeing the video, immediately thought of the video he saw on Kuaijiu before,
The two videos, the same situation, but different results, made it difficult for the guy to accept at the time,
Then I edited the two videos together and posted them on Kuaishu International, and then the video became popular, and it was even transported from Kuaishu International to Kyushu.

And the snowmobile that took the Kyushu Antarctic scientific expedition team members and escaped from death has become the focus of people's attention.
But even if people searched all over, they couldn't find which brand the motorcycle was.
And amid people's curiosity, a large number of people suddenly flooded into the official website of the Antarctic Station, almost all of whom came to inquire about motorcycles.

But now it's the Spring Festival, it's already a holiday, and no one on the website answers this question.

This matter has been shelved here.

Li Zhenhua celebrated the New Year very traditionally, and the customs of the New Year remained the same as when his grandfather was still alive.

After the new year, work resumed on the seventh day of the new year, and Li Yun also came back on the eighth day of the new year.

The days that followed returned to the calm of the past. The house behind the blacksmith shop was almost built, all the external things had been installed, and the rest was just decoration.

The newly established factory area is still under construction, and it is estimated that it will take three to four months before it is fully put into use.

After Li Zhenhua let go of his obsession with rubbing chips with his hands, he devoted all his energy to the manufacture of aircraft mechanical parts.

As for the flight control, avionics and other things of the aircraft model, now we can only buy ready-made chips on the market for research and development.

As time went by, he finally got all the materials needed for the model airplane, and then he started manufacturing the model airplane engine.

Among the materials, the most difficult ones are those used in the core combustion chamber. After a series of overcoming difficulties, these materials were finally obtained.
The single crystal nickel-rhenium-iron alloy in front of him took a lot of effort to get it out.
And for this alloy, he specially created a controllable magnetic field to arrange the single crystals of this alloy.

The manufacture of the engine completely reproduced the craftsmanship in the laboratory, and the experience accumulated in the virtual laboratory before finally came in handy at this time.

The first thing to be manufactured is the casing of the engine combustion chamber. The diameter of the engine is reduced to 29 cm. This casing is the size of his machining center, which is completely capable of manufacturing this.
He put a forty-centimeter-long square single-crystal nickel-rhenium-iron alloy into the machining center. This piece of metal was a new high-temperature alloy smelted earlier.

In the light curtain in front of his eyes, it showed that the internal stress of the piece of metal had almost been released,
Only the little bit of internal stress left, let him knock it out with the help of the analytical eye with a rubber hammer.

After placing the metal, as he pressed the start button, the cutting head of the machining center rotated at a high speed, and the milling cutter cut off bits of debris on the metal.

As the cutter head rotates, debris falls from the originally square metal block, and its shape changes as it is cut.

Slowly as more and more chips are chipped from the metal, the metal never regains its original shape.

After a day of manufacturing, the upper half of the metal block has been made into a circular shape with holes by the machining center.

In two and a half days, a complete combustion chamber casing was taken out of the machining center by him,

And he also stayed in the machining center here for two and a half days, which has been watching the operation of the machine.

The processed casing was taken out from the inside and set aside for later use, and then the impellers, discs and other parts in the combustion chamber were also manufactured.

The processing of the roulette is relatively simple, but the processing of the impeller is somewhat difficult.

Because the machining center he is using now cannot meet the requirements at all in terms of accuracy, which also makes him only use the machining center to make a preliminary rough blank.
After that, he took out the rough blank, fixed it on the vise, and rubbed it by hand with a file.

One blade, one blade was rubbed out in his hands, and the rubbed blades were also installed on the impeller disk by him.

And when it was installed on the wheel, it has already begun to notice the dynamic balance of the impeller.
His eyes and hands are not vegetarian, and his dynamic balance can only be regarded as a minor problem.

The turbojet engine is also taking shape a little bit with his manufacture.

Time slipped away while he was making the engine. After more than a month of manufacturing, the engine was finally rubbed out by his hands.
At the moment, in the center of the workshop, he was standing next to an iron shelf, and the turbojet engine that had been manufactured was placed on the shelf.
