Siheyuan: Starting from a fitter

Chapter 71

After an introduction, everyone got to know each other and got to know each other.

Last night, Zhao Ting gave a brief introduction to her family. There are 12 people in the family, and there are 7 people present today.

Mr. Zhao, whose wife is Qian Xiu, has only two sons, the eldest, Zhao Cheng, and the second, Zhao Xuan.

Zhao Cheng is Zhao Ting's father, a high-ranking official, and his mother, Yuan Sibing, who works in the Propaganda Department; his eldest brother, Zhao Xiangdong, is married and works at the Xizhimen Police Station.

Zhao Xuan has three sons and one daughter, and his wife Zhou Tongyu, the middle-aged beautiful woman just now, works in the Materials Bureau; the eldest Zhao Guigui, the commander of a certain military region, the second eldest Zhao Hongjun, the director of the first division of the Ministry of Mechanical and Electrical, and the third eldest Zhao Jiefang, Zhao Jie, the fourth child, works as a teacher at Wudaokou Technical College and works as a policeman at Dongzhimen Police Station.

After Zhao Jie helped put down the things, she moved three stools and did the rest together.

Next, it was time for the two middle-aged women to perform. Starting from work, they only asked how many meals they would eat in a day.Second Aunt Zhao Ting always asked some embarrassing questions, but fortunately Li Guocheng was young and mature and could handle them all.

The old man and Zhao's father were very serious throughout the whole process and did not interrupt. The old lady was also cheerful and silent.

Half an hour later, the old man obviously lost his patience, stood up and said, Boss, Xiao Li comes to the study with me, Zhao Ting, you chat with them.

Li Guocheng nodded and apologized to everyone else, and followed him into the study. Zhou Jun, who was not included in the calculation, was extremely angry. The original purpose of coming today was to ruin Li Guocheng's meeting with his parents and find an opportunity to confess to Zhao Ting, but the current situation Like a blind date meeting.Zhou Jun knew very well that this should be the old man's idea, so now he even hates the old man.

Entering the study room, there is a row of bookshelves against the wall, which are full of various books; a desk, inside and outside the desk, there are a pair of Taishi chairs, under the window sill is an old-fashioned radiator wrapped in a wooden grill, on which there are two basins of unknown flower.Opposite the desk is a coffee table, the size of a Go board, with a simple sofa on each side of the coffee table.

Li Guocheng bowed and bowed. The old man sat on the Taishi chair outside first, and Zhao's father sat on the sofa in the back. After Li Guocheng waited for them both to sit down, he consciously sat on the sofa near the door.

As soon as the three of them were seated, Zhao Ting pushed the door and came in, bringing two cups of tea and the old man's big tea mug on a tray. Putting her hands on Father Zhao's, Zhao Ting did not help during the whole process, but just watched Li Guocheng working with a smile, then exited the study and took it with her.

Li Guocheng only sat on half of the sofa, with his upper body straight.

"Actually, we all know your situation. You are young and capable. I don't know what plans you have in the future?"

Before Li Guocheng came here, he had considered what he could say and what he couldn't.

"My current main job is machine tool design, and I am also interested in semiconductors. I am studying on my own. I hope that the two can be combined in the future."

"Are you talking about Dawn 1966?"

“That was the first version, and now we are designing semi-automatic machine tools.”

"tell me the story".

"Currently, the machine tools in our workshop are all manually fed, which requires bending down to maintain one movement for a long time, which is easy to fatigue; when processing the workpiece, it is necessary to feed slowly with one hand based on experience. If it is too fast, it will easily damage the cutting edge, and if it is too slow, the efficiency will be too low. Because Most of the machine tool models are too old, and the machining accuracy depends entirely on the feeling of the master's hand, and it must be the same lathe. After changing the lathe, you need to slowly become familiar with it to achieve the previous machining accuracy.

The so-called semi-automatic machine tool means that the master sets the feed speed and distance according to the drawing, and then the subsequent processing is handed over to the lathe. When the preset processing position is reached, the machine tool automatically stops.

The advantage is that the labor master saves physical strength, and the processing accuracy is determined by the lathe. The ability requirements for the processing master are greatly reduced, and it is easier to form economies of scale."

"What is the machining accuracy of the new machine tool?"

"The accuracy of Shuguang 1966 is 0.05mm, and the design accuracy of semi-automatic machine tools is not less than 0.01mm."

"What is the current highest accuracy of the machine tools in your steel rolling mill?"

"According to experience, a level 8 master can reach about 0.01mm, but the time consumed is very considerable."

The old man was the one asking the whole time. At this time, the old man and Father Zhao looked at each other, feeling very surprised by this data.

"Has the Dawn 1966 been put into mass production?"

"We are currently undergoing internal trial production to verify the drawings and processes to ensure large-scale production capabilities."

"Is your factory planning to produce it yourself?"

"The specific situation is unclear." Li Guocheng did not dare to hearsay, even though Li Huaide had said that it might be transferred to the Capital First Machine Tool Factory.

The old man is becoming more and more interested. As an old revolutionary, he is very clear about the importance of machine tools. It is very difficult to purchase high-precision machine tools from abroad. The country is still in the stage of imitating Big Brother. He did not expect that the steel rolling mill would have such a big surprise. .

Judging from Zhao's serious attitude, he was very interested in the current topic, but because of the old man, he didn't ask any questions.

"Tell me about the situation of semi-automatic lathes," the old man continued to ask.

"Currently, the drawing design has been completed and the drawings have been verified. The next step is to trial-produce the prototype."

"Are you responsible for all of this?"

"Yes".

The old man is now very satisfied. As an old revolutionary, he hates the concept of family status. Instead, he likes young people who are useful to national construction.

"Your education level is junior high school, right?" Father Zhao asked the question he had always wanted to ask out of professional sensitivity.

"Yes." Li Guocheng knew that the real drama was coming.

"Can you tell me, where did the knowledge of machine tool design come from?"

Li Guocheng didn't panic at all, he had already prepared all kinds of excuses.There are enough books on mechanical structures on the bookshelves at home, and there is a library as a knowledge base.

"Now that I have chosen to be a fitter, I want to make something, so I prefer to go to the library to read mechanical books. Later, I went to the scrap collection station to buy some. Besides, I have a naturally strong memory and understanding, so it is relatively easier to learn these. ".

Father Zhao turned around and took down a report of more than 100 pages from the bookshelf, and handed it to Li Guocheng.

"Show us what you're capable of".

Li Guocheng nodded, took it over and looked at it for almost half an hour.Maximum 10 minutes if reading and memorizing fully.Then he raised his head and handed it to Father Zhao.

The old man and Zhao's father were both in disbelief. How could this be possible?

"Have you remembered everything?" Zhao's father grabbed the right to speak.

"Yes".

Then Zhao's father rummaged through the contents of the report, tested them in various ways, and found that they were all correct.

"It turns out that genius does exist," the old man said with emotion as he looked at Li Guocheng, and Father Zhao nodded in agreement.

"I have decided on this marriage. You can find a suitable person to propose marriage." The old man made the decision on the spot.

Father Zhao can only nod now.

When the three of them walked out of the study, it was another scene in the living room.

Zhou Junzheng looked at Zhao Ting proudly. Zhao Ting's face was expressionless, while Zhao's mother and second aunt were trying their best to persuade her.The old lady comforted Zhao Jie in a low voice with the same expressionless face, but Zhao Jie seemed to have cried.

Seeing Liu Guocheng coming out, Zhao's mother and second aunt both had bad expressions, but they both tacitly kept silent.

Zhao Ting stood up and walked to Li Guocheng, saluted the old man and said, "Grandpa, we have stayed long enough, let's go back first." Then she turned to everyone, "Grandma, dad, mom, and second aunt, we are leaving first." As he said this, he took Li Guocheng's hand and left.

The old man was so transparent that he immediately expressed his position without waiting for others to speak: "Why are we going? Let's go after dinner!" Then he looked at everyone and said, "I agree to the marriage between Ting'er and Li Guocheng!"

Seeing that Zhao's mother was about to speak, Zhao's father quickly stopped her and winked. Although Zhao's mother was confused, she did not speak again.

Second Aunt Zhao Ting didn't see the situation clearly and said: "Dad..."

Before she could continue, the old man stared at her and interrupted: "You don't have to interfere with Ting'er's affairs, and you are not qualified to do so."

Looking at the old man's expression, the second aunt finally did not dare to speak anymore.

Zhao Jie immediately ran to Zhao Ting, hugged her arms and jumped up, seeming to be even happier than Zhao Ting.Zhao Ting, who had always remained calm, fell into her grandfather's arms and started crying.Li Guocheng stepped forward and patted Zhao Ting on the shoulder to express comfort.

Seeing such a result, Zhou Jun's face was a little distorted, and he stared at Li Guocheng fiercely, wishing he could rush forward and fight.

Feng Tongyu saw that there was nothing he could do, so he found an excuse to leave the small building with Zhou Jun and the reluctant Zhao Jie.
