Chapter 507 Chinese New Year (Second update)

When Liu Hai heard this, he said to Sun Aiguo: "Director, the teaching materials are not of great significance. In the skills competition, just find out what you are good at and follow the old workers. If you really want to learn the teaching materials, there is no need." You can’t learn it in two or three years without a high degree of education.”

Sun Aiguo had no idea how high the technical level of the turboshaft engine and the entire aircraft was, and how many things it contained. It would only take several years to write a textbook on this helicopter.

The meaning of textbooks is to make people learn, so the principles inside must be explained clearly, so textbooks are not realistic.

It's just an assembly process. If you really want to learn it, it will take at least a long time to fully understand what's inside.

"Then I'll do what you said. What do you think should be done in this competition to select the best workers?" Sun Aiguo asked again.

"Director, the competition in the factory must involve all technical workers, even loaders, cooks, etc. I will give you a list of those people who will be needed in the helicopter workshop later." Liu Hai heard this and suggested. .

"Your suggestion is good. I was just thinking about the helicopter." Sun Aiguo nodded when he heard Liu Hai's suggestion. He did think wrong.

Liu Hai spoke again: "Director, I want to set up a separate department for long-term research and development on CNC machine tools. The three-axis CNC machine tool is just the beginning, followed by four-axis, five-axis, etc."

"You write a plan, and I will approve it. If you need people, give it to people, and if you need materials, give materials." Sun Aiguo nodded.

"I plan to temporarily divide half of the maintenance department. In the second half of next year, I will select some people from the university who are good at studying and have strong practical skills to add to the maintenance department." Liu Hai plans to start expanding the maintenance department.

"This is great. There have always been relatively few people in the maintenance department. I also know that the maintenance department has a high level of confidentiality. In addition, there are many technologies involved, and there have been no good candidates." Sun Aiguo said Liu Hai wanted to expand the maintenance department. , I am very happy. Anyone in the maintenance department can become the chief engineer of a large enterprise. There are many things that he knows.

In the past, Sun Aiguo was still somewhat selfish. It was difficult to find people in his factory who were qualified to enter the maintenance department, but what about the others? There are so many schools and so many research institutes, right?

There must be some, but Sun Aiguo feels that the atmosphere in the maintenance department must be guaranteed. Who knows what the virtues of someone transferred from other places are?

Of course, at this time in the country, there is a shortage of overall talent, in all aspects, and most college students are willing to be cadres. Even if they join a factory, they are cadres in technical positions. Who wants to join a maintenance department as a worker?

Before recruiting people, there was no way to tell others the details of the maintenance department, and Liu Hai had no intention to take the initiative, so Sun Aiguo had to turn a blind eye.

Now that the motorcycle factory has its own university, and Liu Hai is willing to train him, Sun Aiguo certainly agrees.

"Yeah." Liu Hai knew what Sun Aiguo was thinking. In fact, leaders like Sun Aiguo who protect their shortcomings are sometimes very good. But I am afraid that some leaders will just listen to their superiors and not care about what their subordinates think.

At the end of January 1973, the first three-axis machine tool in the maintenance department of the motorcycle factory was officially assembled.

Liu Hai placed the paper tape on the paper tape reading machine and pressed the start switch. The paper tape began to move. Reading the paper tape took time.

It takes eight seconds to read the paper tape. This punched paper tape is a manually programmed processing program. Of course, it also requires a fixed knife. However, the test processing did not include fixtures and materials.

The machine tool started to run automatically. At this time, there was no display screen or anything like that. We could only check the operation status of the equipment through the indicator lights.

Everyone in the maintenance department who participated in the project watched the machine start automatically simulating processing. These people are all processing technology veterans, and they can still clearly see the trajectory of the machining feed.

After Liu Hai finished running the program, he felt that there were no big problems, but Liu Hai was not afraid of problems. He was not afraid of problems during the trial operation of the equipment. He was afraid that if there were no problems during the trial operation, problems would occur during the official operation.

Then Liu Hai starts the formal processing. He takes out the prepared materials and puts them on the fixture. After the fixture is put on, he first sets the knife and then tests the knife, that is, the depth of cutting and so on.

Then formal processing begins. As the program runs, the tool begins to cut according to the set trajectory, and the coolant begins to cool the entire material.

As the sound of whining stopped, everyone stared intently. Of course Liu Hai knew that there was no problem. After all, although this program was nominally manual programming, in fact, the results were compared with the automatic programming software in the aircraft carrier space. It was nothing. mistake.

There is also automatic tool change in the middle. At this time, the CNC lathe looks a bit bulky. After all, the relevant control system is not as streamlined as in later generations.

After the parts were processed, Liu Hai picked up the parts, which were still a little warm, and then began to measure them.

This is a simple bearing accessory. The bearings have different precision requirements depending on the use environment. The demand for high-precision bearings is also not small.

"I announce that the motorcycle factory's first three-axis CNC machine tool was successfully tested." After the measurement, Liu Hai breathed a sigh of relief.

Li Dali and others applauded one after another. Sun Aiguo, who had already known the significance of CNC machine tools, clapped quickly when Liu Hai announced success.

"Director, this part can be placed in our museum." Liu Hai picked up the ordinary-looking part.

"Xiao Liu, is there any improvement on this?"

"Yes, this punched paper tape is a bit backward. Foreign countries use tapes, but we just need to take our time here." Liu Hai said.

"Yeah." Sun Aiguo nodded. The meaning of CNC machine tools is that they have a high yield rate. First-level workers can process parts that only sixth-level workers can process.

Of course, complex parts cannot be processed with three axes. They have to wait for four axes, five axes, etc. later.

"Everything is difficult at the beginning. As long as we get started, we can take our time later." Sun Aiguo said again.

After listening to the factory director's words, Liu Hai nodded, and then said again: "Gou Rong, you are responsible for the manufacturing of the second CNC machine tool. Are you confident that you can complete it alone?"

"Yes." Gou Rong replied immediately.

"Okay then, I will leave the task of the second CNC machine tool to you. This CNC machine tool project is a long-term project. You will be responsible for it after it is completed." Liu Hai is going to separate Gou Rong independently and be responsible for the CNC machine tool in the future. part of the matter.

"Promise to complete the task." Gou Rong was extremely happy when he heard this.

As for Li Dali, Liu Hai planned to let Li Dali be in charge of aviation power equipment, which would assist him in this aspect of work.

As for other things, there are also arrangements. There are too many projects that can be developed in the future. Liu Hai has gotten to know people like Li Dali very well over the years in the maintenance department. Gou Rong is more suitable for management in this area, while Li Dali is better at hands-on work. . Sun Aiguo patted Gou Rong on the shoulder and said, "Do it well. Once the workshop is established, just go to other workshops to pick the people you want."

"Yes." Gou Rong nodded.

The CNC machine tool project has just begun, and there are still many things to worry about later. However, Liu Hai is not ready to use four-axis or five-axis until the first batch of CNC machine tool talents in the motorcycle factory reaches a certain number.

"The Chinese New Year is coming soon, how long will your vacation take?" Sun Aiguo looked at the calendar and saw how many days there were until the Spring Festival, and asked Liu Hai.

"Tomorrow." Liu Hai was holding his breath to complete the CNC machine tool and start a new project after the Chinese New Year.

When Sun Aiguo heard this, he asked, "Are you going to Hainan to celebrate the New Year, or are you going to stay in your hometown?"

"Let's go to Hainan." Liu Hai felt moved when he heard this.

I'm really getting a little impatient here in the north. This is the place where I eat every Spring Festival when I go back to my hometown. No matter where I eat, Liu Hai has no shortage of food, so I don't take this place very seriously.

"Our country has changed a lot now. You can take a closer look and see how the animal protection projects are progressing. After all, it's all your money that's being spent." Sun Aiguo said after hearing this.

Liu Hai nodded, and Sun Aiguo continued to ask: "How long will it take?"

"February 2st, I have to go back to my hometown for two days." Liu Hai decided to go out for a walk alone. It would not be good to take anyone with him. After all, the land in Hainan cannot be made public for the time being.

"Yeah." Sun Aiguo didn't say anything. Liu Hai wanted to be alone.

Liu Hai's holiday started the next day. Each workshop has a person in charge, and Liu Hai is mostly responsible for supervision.

Liu Hai returned to his hometown for two days, and then took a train to Hainan. After getting on the train, Liu Hai looked at the scenery outside the window. Liu Hai was the only one in the soft bag. Of course, there were other people from the security department traveling with him.

"Gong Liu, call us if you need anything." The person in charge of the security department entered the soft bag with bangs opening the door.

"Well, I'm sorry to trouble you." Liu Hai knew that the people in the security department had been secretly protecting him. The factory was also responsible for his own security, and other departments would not interfere.

"Hey, we are taking advantage of you, Mr. Liu. We also went to Hainan to see it, just as a tourist. For this mission, the people below are all scratching their heads." The person in charge is in his forties this year.

He was also an old man from the motorcycle factory back then. When Liu Hai entered the factory, there were only ten people in the factory's gatekeepers, communication room, and security guards. Now it has developed into a very large department with a high level of confidentiality.

"That's good, I also said it would delay your New Year celebrations." Liu Hai said with a smile.

"Now that life is getting better, I eat meat whenever I see it. In the past, I didn't necessarily have meat to eat during the Chinese New Year. I am more than ten years older than you. Now we have such a good life, which is unthinkable." Bao (Wu) The person in charge of the Guard (Department) never dreamed that he could manage so many soldiers today, and the equipment in his hands was even more unimaginable.

"Yeah." Liu Hai actually didn't live a hard life, but the memory of the original owner of the body contained many extremely painful days. Watching his relatives starve to death one by one, he will remember that feeling for the rest of his life.

"I was a soldier back then. I was not very old. The army originally refused to accept me. I walked with the army for thirty miles. My feet were broken and the army finally accepted me. I had no choice. My family could not afford to support me at that time. If I didn't Let’s go, everyone will starve to death.”

"There are more than 300 people in our village. When I go back again, there will only be more than 100 people. The rest are missing and starving to death. When my sister died, she wanted to take a sip of millet porridge..." Guard. When the head of the department said this, the grown man burst into tears.

The words of the person in charge made Liu Hai think of something deep in his memory, that is, his relatives in this body were starving to death one by one. Before they starved to death, he had to follow the large group of people and wait until they got there. There.

The original owner of Liu Hai didn't remember where his parents died. On the one hand, he was young at that time, and on the other hand, he just knew he was hungry. On the other hand, he saw too many dead people, so he became numb.

Liu Hai sighed: "When I was young, I don't remember what my parents looked like. I don't even remember where they died."

"Gong Liu, you are the one I admire the most in my life. The first time I met you seems like yesterday. Our factory can celebrate the New Year every day. Most of it is due to you. I have never seen a capable person in my life." Many. But none as good as yours.”

"Our hometown collective has turned in less and less food over the years. Others don't know it, but I know it's all thanks to you. There are hundreds of thousands of people in our factory..." the person in charge continued.

When Liu Hai heard this, he quickly interrupted: "No, this is everyone's contribution. Without everyone's joint efforts, my role alone will be minimal.

"Liu Gong, I don't mean anything else. I just want to say thank you." The person in charge of the security department had actually wanted to say thank you to Liu Hai for a long time, because his position today can be said to be all because of Liu Hai.

If it weren't for bangs, the person in charge of the security department felt that he should still be in charge of more than a dozen people. The motorcycle factory also produced tricycles. Many times he would just lie down when he arrived at the place, and then bring it back to the factory to have it redone. At that time, he could only eat a few times a year. Just meat.

"We just have different divisions of labor. Just like a car, any part is indispensable. It just seems that I am in a key position. Of course I also played a certain role." Liu Hai shook his head and said.

"Liu Gong, you were born twenty years earlier..." The person in charge thought of something else.

Twenty years earlier?

Liu Hai felt that he might have gone to Xiaobenzi's island twenty years earlier. Fat Bear can occupy four islands, how can we occupy one island?

"Same, same." Liu Hai thought of this and said, wondering in his heart, is this the space of his aircraft carrier? If it lands one day, when will it land?

"And what happened at that time?" Liu Hai was a little worried.

"Is it the end of the world?" A somewhat sudden thought popped up in my mind. There was really no way to explain what happened at that time. It shouldn't be a war or something.

"Don't rush out of the aircraft carrier. Otherwise, not only will you not be able to explain clearly, but you may be smashed into meat pies by the tens of thousands of tons of giants." Liu Hai looked at the scenery outside the window and couldn't help but think too much. This was what Liu Hai kept doing. As for the motivation for research and development, no one knows what the future of aircraft carrier space will be like.
