"Mr. Jiang, I heard that you are back, I came to see you." As soon as the second uncle's words fell, people appeared in the courtyard, and after a while, they came to Jiang Yan's living room.

"Yo! The old lady has not seen her for a few days, and I feel that your complexion is much better. The second uncle came to the house and said hello to the old lady.

"That's not it, I don't even want to come back." The old lady said happily.

"Pillar, pour tea for the second uncle, second uncle, sit." Jiang Yan greeted the second uncle.

"Thank you, Mr. Jiang." The second uncle put the wine on the table and happily took the tea poured by He Yuzhu.

"Second uncle, if you have a heart, let the pillar cook some good dishes in the evening, let's have a drink. Taste the good wine brought by the second uncle. Jiang Yan said directly.

Hearing Jiang Yan's invitation, the second uncle happily agreed. He felt like he had come to the right place this time.

"What, boss, second uncle, you talk first, I'll go and see what else is in this market, it's too cold this day, it is estimated that there are a lot of people in Tuncai Tun Grain."

"Da Mao, you go with Zhuzi, bring our non-staple food certificate and go over together, buy as much as you can." Jiang Yan thought about it and felt that He Yuzhu said that this was quite correct, this sudden cooling, especially the cold winter that followed. All kinds of materials will follow the price increase, not only the price increase, with the arrival of winter, the supply of various materials will be even more tight. Take advantage of the fact that it is not yet the depths of winter, and do not stock up on more things, and when the time comes, there will be a shortage of materials, and you will not be able to buy much if you have money. After all, there are a lot of smart people now.

Xu Damao, who was sitting there, answered and then called the sixth son and the stone, and saw that Jiang Yan had something to talk to the second uncle, and the ladies went to the grandmother's room with grandma and Jiang Sirui.

After everyone left, Jiang Yan asked Liu Haizhong. "Lao Liu, are there any big changes in the institute at present?"

"It's a big change." The second uncle thought for a while and said.

"In the early stage, the entire institute was screened, and many people with problems or unclear identities were transferred to other factories, and now the security in the institute is also much stricter, barbed wire fences are installed on the high walls, and all the work cards must be checked when entering and exiting, and the people from the outside are coming in, and the review is also much stricter."

"The biggest change is the production workshop, at present, there are a total of ten workshops in the entire research institute, I am the workshop director of the second workshop, and now the entire experimental workshop has been revoked, most of the workers in it have been added to other workshops, and the skilled workers have been transferred to the tenth workshop, but the inspection of the tenth workshop is quite confidential."

After the second uncle said this, he hesitated for a moment, but still asked Jiang Yan.

"Mr. Jiang, do you know what this tenth workshop is producing?"

"Don't ask what you shouldn't ask, haven't you learned the rules of secrecy?" Hearing Liu Haizhong ask Jiang Yan, Leng Sheng interrupted him.

Jiang Yan knew the matter of the tenth workshop quite clearly, when he was working at the Shengjing Aircraft Factory, the relevant drawings of the workshop had already reached Jiang Yan's hands, and the superior also sent a person to listen to Jiang Yan's plan for the tenth workshop.

Originally, Jiang Yan planned to divide the ten workshops into two, the first half continued to be used as a station for continuing to study CNC machine tools, and the second half was used as a place to imitate high-precision precision equipment projects.

After the last time, after Jiang Yan talked with Chief Engineer Lu and President Xu, Chief Engineer Lu applied to the above for their five master projects to set up a special design room in Jiang Yan's research institute.

These five masters came in, and after Mr. Xu knew, the Zhan-7 project also came in, and the Zhan-7 project also set up a studio, and the Zhan-7 project also came in with the Zhan-6.

Seeing this studio that applied for it one by one, Jiang Yan is too big, and he doesn't have the skill of clone! One by one is still a key project.

After thinking about it, after communicating with them, this special design room asked Jiang Yan to serve as the director of this special design room as an honorary researcher of the research institute.

Jiang Yan, a special design office, is not directly led by the project department or the research institute, but only assists Chief Engineer Lu to solve problems in their projects.

The right to need is in your own hands, and you don't listen to the tune!

In this way, Jiang Yan's other tasks will not be delayed, and Jiang Yan can be found at any time to discuss the problems encountered in their projects.

The biggest drawback is that he, the chief designer of the project, often acts as a trapeze artist and flies back and forth between the two places. In order to create a better five masters, we aviation people can overcome any difficulties!

However, after the superiors heard the news, they deliberately opened a special telephone line, but even so, some things were better solved.

In this way, the transformation plan of the tenth workshop has changed once again.

After Jiang Yan's planning. The team responsible for the reconstruction construction divided the 10 workshops into four and became four relatively independent areas.

The first area is to improve the CNC machine tool project, because the size of the machine tool is relatively large, it needs to be disassembled frequently, so a relatively large compartment is left, mainly to store drawings and temporary meetings of the project team, of course, there is Jiang Yan's separate studio.

The second area, which is a little larger than the first, is full of all kinds of machinery and equipment transferred by the superiors, which can be regarded as a small mechanical processing factory.

Moreover, the workers working here have basically been audited for three generations, so it can be said that there is no flaw in their identity, and the workers here are basically intermediate workers or above, with three seventh-level workers and one eighth-level worker.

The superiors also gave Jiang Yan a list of knowers, and if the task was urgent, Jiang Yan could directly transfer those senior workers recorded above.

The machine tools in the No. 10 workshop are basically what the country can take out at present, which is quite advanced, and Jiang Yan's CNC machine tools are also in it.

What makes Jiang Yan more concerned is that there is a C620-1 machine tool produced by my own breeder.

If you don't pay attention, you can't do it! This machine tool is the first machine tool in our country.

At that time, the workers of Shengjing No. 1 Machine Tool Factory, according to the machine tool drawings provided by Mao Xiong, overcame difficulties under the condition of very backward equipment and technology, and successfully manufactured the C620-1 machine tool in August 55.

The C620-1 is a typical turning horizontal machining machine.

Since its birth, it has been widely used in the machining industry.

The spindle is the main moving part of the lathe, and the quality of the spindle directly affects the machining accuracy of the machine tool.

The C620-1 lathe independently produced by the breeder has a very high quality of spindle components and a high machining accuracy of the machine tool, which is not inferior to the foot basin chicken machine tool that occupied the main body of the domestic factory at that time.

This is also the reason why C620-1 machine tool can play an important role in the development and construction of the national economy.

In order to commemorate this domestic machine tool, which is of great significance to the breeder, the two-yuan banknote issued in 60 years is printed with the figure of workers working hard using the machine tool.

Domestic machine tools have accompanied the breeders through that period of hard construction and laying a modern industrial foundation.

Today's machine tool industry is booming, CNC machine tools with higher precision and higher performance have begun to enter the production line of all walks of life, and domestic machine tools such as C620-1 have gradually withdrawn from the historical stage.

Although the C620-1 lathe fades from sight, it will never be forgotten.

In the Taneke Industrial Museum, a rusty C620-1 machine tool is still preserved, and a large number of visitors come every year to commemorate this former national heavyweight.

It is a symbol of national independence and industrial independence, and the people of the family will remember its contributions, continue to play the craftsman spirit of independence and hard research, and strive for excellence in the manufacturing of the plant, leading it to the peak of the world's class!
