Siheyuan Great Craftsmen

For the next period of time, Zhou Tian had been drawing the design of the boring machine in his mind. However, the boring machine was much more complicated than the rice mill. It was not until seven days later that he had only drawn two-thirds of it.

Zhou Tian did not use the big brother's 2A656 model boring machine for the new boring machine. After all, this model of boring machine is outdated. It was produced by the big brother in the early days. Both in structure and processing capacity, it lags behind the current ones by more than one generation. In Zhou Tian's opinion, it is not worth imitating at all.

Instead, the 50 model boring machine produced by Big Brother in the 2564s is his current target of imitation, not that he does not want to imitate the boring machine design patterns of other countries.

But in this era, most of our country's machine tools come from the support of Big Brother. For workers who are already accustomed to Big Brother's machine tools, imitation Big Brother's machine tools are easier to use and easier to train.

While imitating it, he also made some improvements, such as some adjustments and optimizations on the guide rails, speed changers, columns and boring head frames.

Although the 2564 horizontal boring machine is one of the more precise boring machines at present, Zhou Tian believes that it still has many problems. For example, most of the guide rails are sliding guide rails, which have greater friction and affect the smoothness and accuracy of the movement.

The speed change mechanism of the spindle box may be relatively simple, with fewer gears and a limited speed adjustment range.

The feeding system may rely mainly on manual or mechanical transmission, with a low degree of automation.

The structure of the column and boring head frame may not be compact enough, and the strength and rigidity are relatively insufficient.

In order not to reveal too much, he naturally would not make large-scale improvements, but small changes were still possible.

With the improvements one by one, the design of the entire boring machine gradually changed beyond recognition, and he drew out all the improvement plans he could think of.

From the design drawings, there is no similarity at all with the big brother's 2564 boring machine. If there is an engineer who understands mechanics in the previous life, he can tell at a glance that this is not the 2564 boring machine. It is obvious that this is the T1956 horizontal boring machine produced by the Shenyang Sino-Czech Friendship Factory in 68 in the previous life.

Although the design drawings of the entire boring machine have not yet come out, the design has already formed the prototype of the T68 horizontal boring machine.

Just as Zhou Tian was immersed in the improvements to the boring machine, a knock on the door suddenly sounded, interrupting his thoughts and making the displeasure on Zhou Tian's face flash away.

"Enter!"

As Zhou Tian finished speaking, Dong Tianbao walked in from outside the door.

"Dong Tianbao, what's wrong with you? Did you encounter any problems?"

Seeing that it was Dong Tianbao, a smile immediately appeared on Zhou Tian's face. Obviously, he still had a good impression of this studious young man in front of him.

"No, Chief, the factory director sent someone to deliver the parts you asked the factory to process to the technical department! Everyone asked me to inform you!"

Dong Tianbao shook his head. He had not yet digested the knowledge that the section chief had taught him a few days ago. How could he still encounter difficulties?

"Oh? I didn't expect the factory manager to be so quick. Come on, let me take a look!"

Upon hearing that the parts had been processed, Zhou Tian could no longer sit still. He stood up and walked out of the office with Dong Tianbao towards the technical department.

As soon as he walked into the technical department, he saw several people from the technical department gathered in front of a pile of parts, discussing something. When they saw Zhou Tian come in, several people immediately shouted to Zhou Tian respectfully.

"Senior!"

"Hello, section chief!"

"Section Chief, what are these parts for? They look like rice mill parts to me."

Zhou Tian and the others nodded with a smile. When they heard Liu Wei's words, they were stunned for a moment, then looked at him and smiled: "Liu Wei, not bad, you can actually tell that this is a part of a rice mill?"

"What? They are actually parts of a rice mill?"

Several people in the technical department were suddenly in disbelief. They were just discussing what the parts the section chief had the factory process and send to them were used for. Several of them were even betting with each other. Some of them thought that they must be parts for the section chief's newly developed machine tools, but some others said that they were parts for a rice mill.

Although there were many different opinions, they didn't believe in their hearts that the section chief would develop something as simple as a rice mill.

Unexpectedly, now that they got Zhou Tian’s confirmation, they suddenly lost their composure.

"Section Chief, why did you think of researching rice mills?"

Liu Wei couldn't help but ask the questions in several people's minds. In their opinion, the section chief had developed such an advanced machine tool as the horizontal lathe, and logically he should continue to delve into the machine tool. However, developing this rice mill was a bit too inconsistent with the nature of their factory. After all, they were a steel mill, not an agricultural machinery factory.

"Why? Do you look down on the rice mill?"

Listening to Liu Wei's words, Zhou Tian's expression remained unchanged. He walked straight to a pile of parts, squatted down, checked the precision of the parts, and asked.

"Chief, how could that be? We are a steel mill after all, so if we want to do research, we should be researching machine tools or steel rolling equipment. Isn't it somewhat inconsistent with your identity to research rice mills?"

Perhaps hearing the displeasure in the section chief's tone, Liu Wei immediately laughed awkwardly.

"Okay, you guys, I know what you're thinking. Although the rice mill is simple, it is also closely related to everyone's life. You are all technicians in the technical department. You should know that there is no distinction between high and low technology. Now our country is short of talent. Since we have the ability, why should we be restricted by the direction of research?"

Zhou Tian could naturally understand the meaning of Liu Wei's words and scolded him. Of course, he also knew that his research was indeed not suitable for a steel mill, but he could not tell them the reason.

After checking the parts and seeing that they all met his expectations, he said to Dong Tianbao: "Dong Tianbao, you and Liu Wei pack up these parts and follow me! Everyone else, go and get busy!"

"Okay, Section Chief!"

Dong Tianbao and Liu Wei responded. The others, although full of doubts, did not dare to step forward to ask and could only disperse.

Dong Tianbao and Liu Wei took the parts and left the technical department and came to the cafeteria under the leadership of Zhou Tian.

"Xiaotian, what are you doing?"

He Daqing, who was resting in the cafeteria, saw Zhou Tian and the other two coming in. He couldn't help but stand up, walked up to them and gave Zhou Tian a puzzled look, but his eyes were fixed on Dong Tianbao and Liu Wei who were holding the parts.

"Uncle He, this is the rice mill I recently developed. As you know, we are a steel mill, not an agricultural machinery factory, so if I want to find a place to experiment, I can only choose the cafeteria! Uncle He, do you have any vacant space here?"

Zhou Tian explained to He Daqing.

"I see. Then follow me!"

He Daqing understood Zhou Tian's explanation and brought the three of them to an open space behind the cafeteria. He pointed to the open space and said, "Xiaotian, is this okay?"

Zhou Tian walked forward to take a look. Although he felt that it was a little insufficient, he also knew that this was probably the largest place in the cafeteria except for the warehouse, so he could only nod.

"Okay, let's just use it for now!"

Signaling the two men to put down the parts, Zhou Tian began to assemble the rice mill under the watchful eyes of the three men. With his skillful assembly, a relatively advanced rice mill was assembled in less than an hour.

Originally, the three of them did not take this rice milling machine seriously, but when the entire rice milling machine was assembled, the three of them were dazzled. From the appearance, it can be seen that this rice milling machine seems to be very different from the current rice milling machine.

No matter in appearance or function, it seems to be more complicated than the current rice mills, giving people a sense of advancedness that is inexplicably powerful.

After Zhou Tian installed the rice mill, he looked at his masterpiece with satisfaction, and then said to He Daqing: "Uncle He, does the cafeteria have brown rice?"

"Yes, Xiaotian, wait a moment!"

He Daqing naturally understood what Zhou Tian meant and immediately ran towards the canteen’s warehouse.

"Dong Tianbao, Liu Wei, the two of you go connect the power supply!"

"Okay, Chief!"

Upon hearing this, Dong Tianbao and Liu Wei immediately went to pull the wires to connect the power supply.

In a short while, He Daqing came back with a bag of brown rice, and Dong Tianbao and Liu Wei also connected the power supply.

Zhou Tian checked the rice mill again, motioned to He Daqing and said, "Uncle He, you can pour the brown rice into the rice mill!"
