Scholars in the courtyard.

Chapter 975 Improving Milling Machines
In the room, Ran's mother, Ran Qiuye and others have been waiting for a long time. Ran Hongbing even called into the study twice, but the answer he got was, you eat first.

"What are these two men busy with? They are in the house when they come back and they haven't even eaten!"

"Who knows, coming back looking worried, it must be a work problem."

Ran Qiuye listened at the door for a while, vaguely hearing something about machine tools, but didn't quite understand.

However, the expressions of father and Yang Xiaotao were very serious, it must be a very important matter.

"Then we can't delay our meal! Go and call!"

Ran's mother said, Ran Qiuye responded.

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

However, at the dinner table, everyone could clearly feel that the two of them were absent-minded. They both ate quickly and would exchange a few words in the past, but this time it was purely for the sake of eating.

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

Ran's mother and Ran Qiuye couldn't understand, so the old Taoist smiled and explained.

"The two of them are the same kind of people. They met because of their interests."

After hearing this, the two smiled helplessly.

In the past, Ran's mother had a headache when there was a "bookworm" like Ran's father in the family. She was indifferent to all aspects of her body and could not distinguish between grains and grains. She didn't expect to find a brother-in-law who was like this, but these two fathers were "compatible".

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

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

in the library.

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

Although Ran's father majored in physics, he was also responsible for the design of the casing when he was in Northwest China. Although he didn't know much about instrument design, the basics were there. More importantly, he could read German and could interpret things in the book. come out.

So, while looking at the drawings of the milling machine on the table, I read it against the book and provided opinions from time to time.

"Here, if semi-automation is adopted, manual operation methods need to be changed. This kind of operation control is not feasible."

Ran's father pointed at a drawing and said, Yang Xiaotao looked at it, stretched out his hand to hold his chin, thinking in his mind, and then shook his head, "It's really not possible here, but manual operation is not just about pressing a button, it also needs to adjust the position of the milling cutter. This We also need to consider the heating problem during processing, so it is not appropriate to simply change this."

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

"So, here, here and here."

Yang Xiaotao clicked on the drawing with a pencil, "Everything needs to be changed!"

Ran's father nodded, and his whole body was affected by a single move, especially for precision machine tools.

"Of these three places, this is the easiest!"

Yang Xiaotao started from the problem points pointed out by Ran's father, spread them out in three directions, and then attacked each direction. This simple and clear idea was approved by Ran's father.

Of course, there is also a risk in doing this, that is, the changes will be final and unable to echo other parts, thus requiring larger-scale changes.

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

Even after it's done, actual construction is required to ensure the design is correct.

This process is particularly long.

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

Time, energy, materials, and fear of failure.

Ran's father knew all this because they had experienced this kind of thing during those years in the northwest.

It was just the serious look of veteran Yang Xiaotao that reminded him of his past self. At that time, he was still young and frivolous, and also full of passion.

That person is not young.

The dream of youth is still a dream!
"When I was in Quancheng, I made a precision disc for their grinder there."

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

Father Ran was interrupted from thinking by Yang Xiaotao, and then he saw Yang Xiaotao mumbling.

"Precision disk?"

"Yes, that's right."

As Yang Xiaotao spoke, he pulled out a notebook from the drawer, rummaged through it, handed it to Ran's father, and explained, "Last time I went to Quancheng Machine Tool Factory to help..."

"Then we'll improve and deal with this!"

"It's actually just a gear paired with a precision disc to achieve manual controllability."

As Yang Xiaotao spoke, Ran's father's eyes stared at the drawings in the notebook and became brighter and brighter.

"This is a good idea. We can install this on grinders in the future, which will greatly improve efficiency!"

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

Ran's father did not answer in a hurry, but thought carefully and carefully.

Yang Xiaotao was not in a hurry and just explained his plan from the side. Ran's father also asked about the design requirements from time to time.

The two discussed for a while, and half an hour later, Ran's father nodded, "It seems that we can also build one for the milling machine."

“This allows you to control the distance between the milling cutter and the part, allowing you to mill.”

“Besides, it doesn’t require too much pressure to operate!”

Yang Xiaotao nodded and continued the discussion.

Ran's father and Yang Xiaotao had been discussing in the study until midnight. Seeing this, Ran Qiuye did not go back with his family. Since there were many rooms at home, he arranged for his family to rest.

Yang Xiaotao was lying on the bed, hugging his wife from behind. He felt a fullness in his hands, but his mind was filled with drawings, structures, and shapes.

When I woke up the next morning, Ran's father didn't sleep well either.

The two of them felt like they were following a book. They wanted to read it in one sitting, but they didn't have so much time and energy. They could only think about it and remember it.

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

Seeing the two people's appearance, Ran Qiuye asked Ran's mother to stay at home.

We are all a family anyway and don’t need to see anyone outside.Moreover, she also knew that her father's time at home was running out.

Ran's mother didn't refuse. She was happy to help look after the children here.

In the courtyard, everyone knows the situation of the Yang family, Ran's mother also knows him, and he has also gotten to know Ran's father in the past two days. People in the courtyard are very polite.

It's almost the same here as in a large courtyard.

In the Jia family, Qin Huairu cooked a meal and let the three children eat it. They handed Xiaodang and Sophora japonica to the eldest mother to help look after them, and then went out with a basket and a stick.

The basket contained some patchwork fabrics, the masterpieces of the past few days.

In the compound, no one helped her family, and even when she was walking around, Qin Huairu had to let go of her unnecessary thoughts and start running for a living.

Two days ago, I went to the sub-district office to explain the situation. Considering Qin Huairu's situation and having a sewing machine, the sub-district office assigned some fabric sewing work, which cost a few cents a day.

Qin Huairu had no choice, it was better than sweeping the floor on the street.

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

As for Banggen, he was sent to school by Qin Huairu.

During this time, my legs and feet have almost healed, and it’s okay to stay at home.

In addition, all the children in the courtyard went to school, so it was not a problem for Bangge to stay at home.

Of course, Qin Huairu's heart is more about letting Banggeng study hard.

A few days ago, I heard that the children in Yangjiazhuang were admitted to junior high school. Not only were they given a lot of things, but they also received scholarships, which cost three or four yuan a month. She was jealous of the fact that she could make money at such a young age without even going to work.

Furthermore, sending her children to school is also a solution she has long thought of. Only going to school can change the current predicament.

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

After taking Bangeng out of the house, as soon as he walked out of the alley, the sound of a bicycle came from behind. Qin Huairu pulled the reluctant Bangeng to the side, and then saw Yang Xiaotao passing by on a bicycle.

"Banggen, learn to read and write well. When you grow up, my mother will depend on you!"

Banggeng shrugged his head. He had a headache when he heard about going to school, but he had no choice in this matter. He could only shrug and nod.

"Good son, study hard. Once you study well, you can find a good job. Once you have a job, you can find a wife in the city and live a good life. Your mother will take care of your children when the time comes. You work hard and earn money..."

Qin Huairu walked with Banggian, looking forward to the bright future.

Although placing all hope on future generations is an evasive attitude and an extremely irresponsible behavior.

But for Qin Huairu, this may be her only thought at the moment.

Banggeng nodded silently. As for the future, he was still waiting for his eldest brother to come out and do something big.

……

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

One of the two machine tools makes a punch press, and the other makes a milling machine, with almost no downtime.

When I came to the workshop, Chen Bin was leading people to work, and the second milling machine was about to be finished.

In addition, the order for punch machines is not small, and the factory also needs to purchase pressure cookers for production. Now the production tasks are increasing, and more punch machines are needed.

After watching for a while, Yang Xiaotao went to the tractor workshop to check on the progress. The person operating the milling machine was Zhou Hong, who was specially seconded from the R&D Department in order to increase the success rate.

Yang Xiaotao watched for a while and realized that Zhou Hong's skills were indeed better than those of yesterday's workers, but they were not 100% correct, and with the consumption of physical strength and energy, this accuracy rate could not be guaranteed.

Then Yang Xiaotao returned to the office, spread out the drawings, and continued to study.

In the office, Lou Xiao'e is sorting out information. She has not been to Yang's house in the past two days, mainly because there are many people in Yang's house, and it would cause trouble for her to go.

Besides, there has been a lot going on in the factory recently.

For the production of machine tools, it is said that factories throughout the [-] cities have sent requests, hoping that the steel rolling mill will support a machine tool.

This is just a punch machine. Now that milling machines have been produced, it is expected that there will be another wave.

The successful development of diesel engines and the smooth production of tractors made the steel rolling mill even more prominent.

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

"Director, this is the detailed situation in August, tractor output and income and expenditure."

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

Lou Xiao'e placed several completed reports in front of Yang Xiaotao. Yang Xiaotao took them and only glanced at them twice. Then he signed to express understanding and continued to look at the drawings.

When Lou Xiao'e saw this, she didn't bother him. 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.

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

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

"Is this a milling machine?"

After looking at the drawings, Yang Youning thought it looked familiar and asked.

When Yang Xiaotao saw Yang Youning coming, he just raised his head and said hello. At this moment, his head was full of drawings and designs, so he just nodded when he heard this.

"Yes, Hong Mian No. [-]!"

"I plan to improve it and see if I can make Hong Mian No. [-]!"

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

Seeing this, Yang Youning became even more confused. If the milling machine has not been built yet, what else is there to study?

Red Mill No. [-]?

The order for Hong Mian No. [-] has just come down, and they haven’t even started delivery yet. Are they planning to work on Hong Mian No. [-]?

This update is a bit fast.

At least let Hong Mian No. [-] shine. If there is No. [-], who needs No. [-]?
Will those manufacturers who have received Hongmi No. [-] come to return the product if they learn that there is a better one?
Yang Youning's mind was spinning rapidly, and he quickly thought of several possibilities, and then thought about countermeasures for each possibility in advance.

Is there any reason to exchange the things that have been sold?
Why does it say on the wall of the supply and marketing cooperative, "No returns or exchanges will be made when leaving home." '
