Siheyuan: Rebirth of a comfortable life starts with Shazhu

He Yuzhu didn't care who was asking the question at this time. He smiled awkwardly and said, "Leader, people have urgent needs. I have to go to the toilet first.

If you have anything to say, let me know when I get back."

As He Yuzhu said these words, he trotted out.

But the other party was not arrogant. Instead, he reached out and took the information from He Yuzhu's hand.

After He Yuzhu finished defecating and felt refreshed, he washed his hands and walked out of the toilet leisurely.

The leader was standing outside the toilet, looking with interest at the new buds on the old trees in the yard, and the chirping of swallows and flying around the eaves.

A tabby cat was crawling on the roof, staring at the flying sparrows.

"Leader, I am really sorry for being rude just now. Thank you." He Yuzhu bowed slightly to the leader to show his gratitude.

Of course, He Yuzhu didn't know why the other party wanted him to do something, so his tone of voice inevitably became serious.

"Comrade He, you don't have to be polite. Everyone has three urgent needs. Let me introduce myself. My surname is Chang." The leader opposite handed the information in his hand to He Yuzhu and extended his hand to invite him. The meaning was very clear, that is, he really had something to discuss with He Yuzhu.

He Yuzhu was also absent-minded, and he glanced at the tabby cat from time to time.

The key is what he can think of. He has just said everything. Now he has nothing in his mind and can't think of any good ideas.

Another thing is that He Yuzhu wanted to bring some changes to this society with his meager strength.

But he didn't want to catch the attention of these big guys too early.

Even with Begonia, although He Yuzhu was full of respect, he didn't want to get too close to her.

If you are too high up, the pressure will be too great.

It is not suitable for someone like He Yuzhu who seeks comfort.

"Why, Comrade He, are you so concerned about that cat?" Comrade Chang asked with a smile.

He Yuzhu nodded shyly, but pointed at the tabby cat on the roof opposite and said, "I was wondering if it would pounce down."

I don't know if those sparrows were deliberately teasing the old cat, as they were flying back and forth more than a meter in front of the eaves.

The roof was about four meters above the ground, and if the tabby cat pounced down, there would only be two results.

Or pounce on the birds and then fall down.

Or you may not be able to catch the bird and the fall will be in vain.

Although cats have strong jumping abilities, a tabby cat can still land safely after falling from such a height.

But whether to jump or not is a question of courage.

He Yuzhu is really not solving a puzzle. If he had this kind of brain, he would not have made those choices in the first place, which resulted in limiting his career ceiling early on.

Comrade Chang also looked at the aggressive raccoon cat with interest, but said with a smile: "I think it will jump out, it's a habitual offender.

Judging from its crawling posture and the look in its eyes as if it was pretending to be asleep, this is probably not the first time it has done this."

He Yuzhu glanced again at the place where the tabby cat was lying. It was lying at the corner of its wing. If it weren't for the sunlight reflecting off the tiles, He Yuzhu would not have noticed it just now.

If the cat wants to pounce, it can use the wing angle to gain some leverage. It is indeed the best position for the cat to lurk.

He Yuzhu couldn't help but nodded, agreeing with Comrade Chang's words.

Comrade Chang laughed out loud, but this startled the tabby cat.

The cat stood up and bent its body, meowing angrily at this side, then took cat steps, went around the roof ridge and fled away.

Comrade Chang's laughter stopped abruptly. He Yuzhu was nervous, but he couldn't help but smile. He said, "We just counted one less. It was human intervention." Comrade Chang smiled and said, "Although we stopped it, we also saved a swallow, which is a good thing."

Whether it's gossip or probing, there's always a time to finish.

Comrade Chang asked He Yuzhu about the main business. He hesitated for a moment and then asked, "Comrade He Yuzhu, I understand what you said about the material upgrade. It is a problem that requires our technicians to conduct countless experiments to solve.

But you mentioned upgrading the basic processing technology, what suggestions do you have on this?"

He Yuzhu thought for a moment, flipped through the materials he had prepared, took out a sheet and handed it to Comrade Chang.

He Yuzhu smiled and said, "The solution lies here."

The document that He Yuzhu pulled out was exactly the development of CNC machine tools that he was researching.

It should be said that the development of CNC machine tools in our country is not very good now, since the first CNC machine tool was developed in Sijiu City more than ten years ago.

In recent years, due to the blockade from outside, progress in this regard has been slow.

Now we still use simple CNC, that is, mainly stepper motor drive.

The positioning accuracy can only be controlled within plus or minus 0.05mm, and steps are easily missed in the middle, requiring manual observation and compensation on the side.

The error of mainstream machine tools in the world today is already below 0.01mm.

But those things were too complicated, and He Yuzhu's knowledge was not enough to explain them, so he didn't say anything just now.

However, He Yuzhu can still brag a little.

He Yuzhu scratched his head and smiled bitterly: "Leader Chang, you should also know that I am a latecomer in industry, and I don't understand too much about professional things.

Now we still rely on the superb skills of our workers to produce some things.

This indeed proves that man can conquer nature.

But we should also be clear that the skills of those old masters are difficult to replicate.

So if we want to upgrade the processing technology, we must first sharpen the tools.

That's it.

I checked some information. The positioning accuracy of the CNC machine tools sold by Ameritrade can reach plus or minus 0.005mm, while our machine tools can only reach 0.05 at most, and the repeatability can only reach 0.025.
I also asked some experienced workers, and they said that they can control the accuracy between 0.01 and 0.02 by hand rubbing.

This is the gap, and also where we need to improve.

If we can solve this gap, as long as we have a large number of high-quality industrial workers, we can achieve industrial upgrading of the entire industrial processing level."

He Yuzhu had a lot of difficulty saying these words.

For example, for some professional data, he had to look at the underlined parts in the information and explain them to Comrade Chang.

There is no way around it. This is He Yuzhu's level and he has already tried his best.

Comrade Chang's expression also became serious. He nodded and said seriously, "Indeed, this issue has been noticed.

But this is not simply a manufacturing problem.

There are so many aspects involved.”

He Yuzhu shrugged and continued with a wry smile, "So we can only solve the problems we can solve.

Earn more foreign exchange and give those researchers more bargaining chips." (End of this chapter)
