In the house, Ran Mu, Ran Qiuye and others had been waiting for a long time, and Ran Hongbing even went into the study and called twice, but the answer they got was that you eat first.

"What are these two doing? When I came back, I was in the house, and I didn't eat anything! ”

"Who knows, when I come back with a preoccupied look, it should be a problem at work."

Ran Qiuye listened to it at the door for a while, and vaguely heard something about the machine tool, and he didn't understand it very well.

However, the expressions of father and Yang Xiaotao are very serious, it should be a very important thing.

"That can't delay eating! You go and scream! ”

Ran Mu said, Ran Qiuye should go down.

It wasn't until Ran Qiuye went in for a while that the two of them came out of the study and started eating.

It's just that at the dinner table, everyone obviously felt that the two of them were absent-minded, they were both eating fast, and they would say a few words in the past, but this time it was purely for eating.

Even the wine prepared by Ran Qiuye didn't drink it, so he ate it hastily and went back to the study again.

Ran Mu and Ran Qiuye couldn't understand it, so they explained with a smile.

"These two are the same kind of people, and they are interested, and they have met together."

After hearing this, the two smiled helplessly.

In the past, there was a 'nerd' like Ran's father in the family, and Ran's mother already had a headache, she was not diligent, and she didn't distinguish between grains, and she didn't want to find an uncle.

But this is good, it shows that the two get along.

Of course, in Ran Qiuye's heart, these two people have always been like this, the best.

In the study.

The desk had been emptied, and Yang Xiaotao spread out the drawings of the milling machine, and the entire table was covered with drawings.

Although Ran's father studied physics, he also worked on the design of the shell when he was in the northwest, although he didn't know much about instrument design, but the foundation was there, and more importantly, he could read German and decipher the things in the book.

So, while looking at the drawings of the milling machine on the table, I flipped through the books for a while, and gave advice from time to time.

"Here, if semi-automation is adopted, it is necessary to change the manual operation mode, which is not feasible."

Ran's father pointed to a drawing and said, Yang Xiaotao looked at it, stretched out his hand and pinched his chin, thinking in his mind, and then shook his head, "It's really not possible here, but manual operation is not simply pressing the button, and the position of the milling cutter needs to be adjusted. ”

Yang Xiaotao vetoed Ran's father's proposal, and Ran's father didn't care, he felt that Yang Xiaotao was right.

"So, here, here, here."

Yang Xiaotao dotted on the drawing with a pencil, "All changes need to be made!" ”

Father Ran nodded, and moved his whole body, even more so with precision machine tools.

"Of the three, this is the easiest!"

Yang Xiaotao started from the problem points pointed out by Ran's father, spread out three directions, and let each direction be overcome, this simple and clear idea, Ran's father agreed.

Of course, there is a risk that this will end up in the end and will not be able to echo the rest of the work, requiring a wider range of changes.

And this kind of change, in the initial stage, it is impossible to judge whether it is correct or not.

Even after it is done, it needs to be actually built to ensure the correctness of the design.

This process is particularly lengthy.

This is why the domestic research on advanced machine tools has been sluggish.

Time, energy, materials, and the fear of failure.

Father Ran knew all this, because in those years in the northwest, they had experienced this kind of thing.

It's just that the serious appearance of the old Yang Xiaotao reminded him of his former self, at that time, he was also young and frivolous, and he was also full of enthusiasm.

No one is young.

A young dream is still a dream!

"When I was in Springs, I made a precision disc for their grinding machine."

Suddenly, Yang Xiaotao slapped his forehead, and the whole person stood up excitedly.

Ran's father was interrupted by Yang Xiaotao, and then he saw Yang Xiaotao muttering.

"Precision disk?"

"Yes, it is."

Yang Xiaotao said, pulled out a notebook from the drawer, then rummaged through it, handed it to Ran's father, and explained on the side, "I went to Quancheng Machine Tool Factory last time to help..."

"Then I'll improve it and do this!"

"In fact, it is a gear with a precision disc to achieve manual maneuverability."

As Yang Xiaotao spoke, Father Ran's eyes stared at the drawings on the notebook, becoming brighter and brighter.

"This is a good idea, and the grinder can be equipped with this in the future, which will improve the efficiency a lot!"

Yang Xiaotao nodded, "Dad, look at this thing, it's actually a controller, similar to the gearbox on the machine tool, I think it can be designed into it!" ”

Father Ran did not rush to answer, but thought carefully and was very cautious.

Yang Xiaotao was not in a hurry, but he was explaining his plan on the side, and Ran's father also asked about the design requirements from time to time.

The two discussed for a while, and after half an hour, Father Ran nodded, "In this way, you can also make one on the milling machine." ”

"This allows the milling cutter to control the distance from the component and thus the milling."

"Besides, it doesn't need to be too stressful to operate!"

Yang Xiaotao nodded, and then continued the discussion.

Ran's father and Yang Xiaotao have been discussing in the study until midnight, and Ran Qiuye didn't go back to his family when he saw this, anyway, there were many rooms at home, so he arranged for his family to rest.

Yang Xiaotao was lying on the bed, hugging his daughter-in-law from behind, with a full feeling in his hands, but his mind was full of drawings, structures, and shapes.

When he got up the next morning, Ran's father didn't sleep well.

The two of them felt like they were chasing a book, and they couldn't wait to read it in one go, but they didn't have so much time and energy, so they could only think about it and think about it.

After breakfast, Ran's father wanted to go to the library to see if there was any information in this area, and Yang Xiaotao took the drawings to the rolling mill to continue the design.

Seeing the appearance of the two, Ran Qiuye asked Ran's mother to live at home.

Anyway, it's all a family, and they don't need to see each other.

Moreover, she also knows that her father's time at home is running out.

Ran's mother didn't refuse, here, she can still help to see the child, and she is happy.

In the courtyard, everyone knows the situation of the Yang family, and Ran's mother also knows her, and she has also learned about Ran's father in the past two days, and the people in the courtyard are very polite.

It's like in a compound here.

Jia's family, Qin Huairu cooked a meal, let the three children eat, handed over Xiaodang and Huaihua to an aunt to help watch, and then carried the basket and went out with a stick terrier.

The basket is filled with some sewn fabric, which is the masterpiece of these days.

In the compound, no one helped their family, even if they usually walked around to prevent her, Qin Huairu had to let go of the extra thoughts in her heart and start running around for a living.

Two days ago, I went to the street office to explain the situation, and the street office took into account Qin Huairu's situation and had a sewing machine, so they divided some fabric sewing work, and they could pay a few cents a whole day.

Qin Huairu didn't have a choice, it was better than sweeping the floor on the street.

Although, that would save a meal, this kind of work made her feel more decent.

As for the stick terrier, he was sent to school by Qin Huairu.

During this time, my legs and feet were almost better, and it was okay to stay at home.

In addition, the children in the courtyard all go to school, and it is not a problem for the stick terrier to stay at home.

Of course, Qin Huairu's heart is more about letting the stick terrier study hard.

A few days ago, I heard that the children of Yangjiazhuang were admitted to junior high school, not only gave a lot of things, but also got a stipend, which was three or four yuan a month.

Moreover, letting her children go to school is also a way out that she has long thought of, and only going to school can change the current predicament.

In this regard, Yang Xiaotao is a role model for the whole hospital.

went out with a stick terrier, just walked out of the alley, there was a sound of riding behind him, Qin Huairu pulled the reluctant stick terrier to the side, and then saw Yang Xiaotao riding a bicycle past him.

"Stick terrier, learn to read hard, when you grow up, your mother will rely on you!"

The stick terrier shrugged his head, and he had a headache when he heard about school, but he had no choice but to shrug and nod.

"Good son, study hard, you can find a good job if you study well, you can find a daughter-in-law in the city if you have a job, live a good life, your mother will watch the child for you when the time comes, you can work hard to earn money..."

Qin Huairu led the stick terrier to walk, and by the way, he looked forward to a better future.

Although betting all hope on future generations is an evasive attitude, a highly irresponsible behavior.

But for Qin Huairu, this may be the only thing she thinks about at the moment.

The stick terrier nodded silently, for the future, he is still waiting for the eldest brother to come out and do something big.

……

After Yang Xiaotao rode to the rolling mill, he first went to the workshop to have a look.

The two machines, one for punching and the other for milling, have little to no downtime.

When he came to the workshop, Chen Bin was leading people to do it, and the second milling machine was about to be made.

In addition, the order of the punch machine is not small, and the production pressure cooker in the factory also needs to be added, and now the output task is more and more, and more punches are needed.

After watching for a while, Yang Xiaotao went to the tractor workshop to see the progress, and it was Zhou Hong who operated the milling machine, who was specially seconded from the R&D department, in order to increase the success rate.

Yang Xiaotao looked at it for a while, Zhou Hong's skills are indeed stronger than yesterday's workers, but they are not 100% correct, and with the consumption of physical energy, this accuracy is not guaranteed.

Yang Xiaotao then returned to the office, spread out the drawings, and continued his research.

In the office, Lou Xiao'e was sorting out the information, and she didn't go to Yang's house in the past two days, mainly because there were many people in Yang's family, and she would make trouble if she went.

Besides, there have been a lot of things going on in the factory lately.

The production of machine tools is said to have been sent by factories throughout Sijiu Castle for the support of a machine tool from the rolling mill.

This is just a punch, now that the milling machine has been made, it is estimated that there will be another wave.

The successful research and development of diesel engines and the smooth production of tractors have made the rolling mill shine.

This makes them very proud to be part of the rolling mill.

"Factory director, this is the breakdown of August, the output and income and expenditure of tractors."

"This is the task situation of the machine ...

Lou Xiao'e put a few completed reports in front of Yang Xiaotao, Yang Xiaotao took it and just looked at it twice, then signed it to express his understanding, and continued to look at the drawings.

Lou Xiao'e didn't bother when she saw this, the whole factory has been busy recently, and Yang Xiaotao has long been used to this situation.

Just as Lou Xiao'e walked aside, Yang Youning suddenly walked in at the door.

Glancing at Lou Xiao'e, Yang Youning walked up to Yang Xiaotao.

Seeing that Yang Xiaotao was pondering the drawings again, he endured his worries and stepped forward to check.

"This is a milling machine?"

Glancing at the drawings, Yang Youning felt familiar and asked.

Yang Xiaotao just raised his head to say hello when he saw Yang Youning coming, and his head was full of drawings and designs at this time, and he just nodded when he heard the words.

"That's right, Red Mill One!"

"I'm going to improve it and see if I can make the second red mill!"

In view of Yang Youning's naming method, Yang Xiaotao replied without raising his head.

Seeing this, Yang Youning was even more puzzled, didn't the milling machine be made, and what else was studied?

Red Mill No. 2?

The order task of the red milling No. 1 has just come down, and they have not yet started to deliver, so they plan to dry the red milling No. 2?

It's a bit fast.

It's good to make the red milling No. 1 shine, if there is a No. 2, who wants No. 1?

Those manufacturers who received the red milling No. 1 learned that it was even better, will they find a door-to-door return?

Yang Youning's head spun quickly, and he quickly thought of several possibilities, and then thought about countermeasures in advance for each possibility.

Is there any reason to exchange what is sold?

How is it written on the wall of the supply and marketing cooperative, 'When you go out, you will not return it.' ’
