Siheyuan Great Craftsmen

"Xiaotian, you are a boy, so you definitely can't wash clothes cleanly. Let your aunt help you wash them!"

As He Daqing's wife said this, she wanted to take the basin from Zhou Tian's hand.

"No, Auntie, really! I can do it myself!"

Zhou Tian was a little panicked for a moment. You know, there were his just-changed underwear in there. If someone knew about it, he would be in trouble.

A pair of hands tightly grasped the basin, exerted a little force, shook off her hands, and hurriedly ran home.

When he got home, he finally suppressed the impulse in his heart. After a long time, he regained his composure and started washing in the house. After washing, he hung the clothes out to dry.

Seeing his second brother busy in the kitchen, Zhou Tian couldn't help feeling a little relieved.

For the first time, he felt that his second brother had grown up, and he felt like a son had grown up. Although Zhou Hao was his younger brother, not his son, the feeling was the same.

After breakfast and watching Sanxiao go to school, he rode his bicycle to the steel rolling mill again. When passing by the intermediate courtyard, he didn't even dare to stop for a second.

After entering the steel rolling mill, parking the bicycle, and walking into the abandoned workshop, I saw that Master Liu Wuming and Master Zhang had already prepared all the materials. The moment they saw Zhou Tian, ​​there was a flash of anticipation in the eyes of the three of them.

"Master, Master Zhang, Second Brother, good morning!"

Zhou Tian greeted the three of them.

"Good morning, little one!"

"Morning, Master Zhou!"

"Morning, Junior Brother!"

Liu Wuming and the other two, who had been waiting impatiently, responded verbally, but their eyes were looking at his backpack.

Zhou Tian naturally understood what the three meant. He took out a stack of drawings from his backpack and handed them to his master and Master Zhang.

"Master, Master Zhang, this is your next task. Thank you for your help!"

"What's the trouble? Isn't it all for the country?"

The two men took the drawings. Master Zhang said something casually, but his eyes were fixed on the drawings for a long time, unable to come back to his senses. Master Liu Wuming also looked at the drawings in his hand without saying a word.

"Great! It's really great!"

After a long while, the two came back to their senses and couldn't help but exclaim in admiration.

Although the parts processed previously had made them guess that Zhou Tian's lathe was not simple this time, looking at the parts to be processed now made them even more certain of this guess.

With the drawings, the two naturally had no time to talk nonsense with Zhou Tian. They turned around, started the machine tool and began processing, and Liu Yuan naturally followed his master happily.

Looking at the three people who were surrounding him just now, they all started to get busy. Zhou Tian, ​​who was about to say something, had to swallow it back.

But at the same time, I also gained a new understanding of the self-consciousness of the workers of this era. Perhaps many people in later generations will say that large collectives are prone to breed lazy people.

After all, you will get the same salary whether you work or not, and you will not be fired. However, only people who lived in this era know that the sense of ownership of people in this era is simply incomparable to that of later generations.

Let’s not talk about anything else, just take the steel rolling mill where Zhou Tian works. Although it has not yet been transformed into a public-private partnership, as long as the factory receives a task from the state, everyone will consciously complete it as soon as possible.

Of course there are lazy people, but they are only a minority. Most mainstream workers have a heart to serve their country.

In the blink of an eye, half a month had passed. As parts were processed one after another, all the parts of the new lathe were completed.

On the day of assembly, Deputy Director Yang and Technician Nie came to the abandoned workshop, and Zhou Tian began to assemble in front of the five people.

Since he already had a detailed structural diagram in his mind, the assembly process was not difficult. While the five people were somewhat stunned, Zhou Tian assembled it exceptionally smoothly, without even the slightest pause in the middle.

Not to mention Deputy Director Yang and his two companions, even Liu Wuming and the other two were shocked by Zhou Tian's assembly speed. They had originally planned to wait until Zhou Tian opened his mouth before going up to help.

Who would have thought that Zhou Tian never spoke a word from beginning to end, his eyes gleamed with confidence, and his hands kept assembling the lathe.

The structure of the lathe is divided into six parts, including the headstock, exchange gear, feed, slide, tailstock and body.

The most important part of the lathe is the spindle box, which is used to support and drive the lathe spindle and chuck to rotate. The spindle can obtain various speeds by changing the position of the handle outside the box.

The chuck is connected to the main shaft and drives the workpiece to rotate together.

The exchange gear transmits the spindle transmission to the feed box, and cooperates with the feed box to cut threads with different pitches.

The feed box utilizes a gear structure to transmit the transmission requirements of the main shaft to the slide box through a polished rod and a lead screw.

As for the slide, tailstock and body, they are also closely related to the accuracy of the lathe. Negligence in any part of these will affect the accuracy of the lathe.

Especially the car body, the two precise guide rails on the car body are related to the precision of processing.

Although Zhou Tian seemed to be able to see the entire assembly process going very smoothly, only Zhou Tian himself knew how difficult it was. Any problem would affect the precision of the entire lathe, so he could not afford to be careless.

The height and stability of the car body were also carefully calculated by him.

An hour later, under the eyes of Deputy Director Yang and Technician Nie, Zhou Tian assembled a precise and shocking lathe.

When Zhou Tian connected the power supply, he clapped his hands and looked at the lathe that he had assembled with his own hands with satisfaction, revealing a relaxed smile.

"Master Zhou, is the lathe assembled?"

Seeing Zhou Tian stop, Technician Nie couldn't help but take a step forward, came to the lathe, his eyes shining, and asked anxiously.

"Yes! Technician Nie, the lathe has been assembled!"

Zhou Tian nodded, and Nie Guodong felt relieved immediately.

"Can I try it then?"

"Of course, Technician Nie please!"

Zhou Tian said as he moved aside. Nie Guodong started the lathe impatiently. As a result, he heard a slight noise, which made his eyes reveal a hint of disbelief. He picked up a piece of steel and started processing it.

The more he used it, the more shocked he was, especially the lathe's smooth operation and slight noise, which made him love it so much.

The continuous improvement of the precision of parts made him feel even more the terrifying performance of this lathe.

After the parts were machined, he measured them with a ruler and exclaimed, "What a terrifying precision!"

You know, although he is a technician in the factory, he has been promoted step by step from the bottom. Even if his locksmith skills have not reached level eight, they are at level seven.

However, the parts he had just processed using this lathe had actually reached the level of an eighth-grade worker, which shows how powerful this lathe is in improving the performance of fitters.
