Don't underestimate such a small action, when a machine, hundreds of other parts, through screws, or assembly, after assembling together.

When working together, the resonance generated by the mechanical operation often causes noise and vibration, and these slight noises and vibrations are the main reasons that affect the accuracy of machining.

When you use the assembly process of others, when you assemble each splicing workpiece, you can minimize the vibration and noise of the machine, so as to ensure the accuracy of machining to the greatest extent.

This is the essence of the Japanese assembly process, and it is also the essence of the Japanese man-made car, why the cars made by the Japanese in later generations are used all over the world, and why they are labeled as reliable.

It is nothing more than because people are very careful when assembling, resulting in low noise, low vibration, and comfortable driving, and such assembly can not only improve driving comfort, reduce vibration and noise, but also be the health of the car, to ensure a longer time.

This is also a major reason why Japanese cars are durable.

In addition, in order to alleviate the vibration during machining and affect the machining accuracy, the rubber is applied to the screws, or rubber pads are placed under some workpieces with relatively large vibrations, which are all methods developed by engineers from the assembly department of Toyota.

Later, it was gradually extended to all machinery manufacturing industries in Japan, and these methods were generally secretly protected by the Japanese and never announced to the public.

Such a little secret, a small means. Until 2,000 years later. With the new generation of big-mouthed Japanese growing up. It was gradually leaked out.

At that time, Europe and the United States, especially the Germans, knew the secret of the Japanese to ensure machining accuracy, so they improved some of their processing techniques and processes, which retained their position in the field of machining.

Otherwise, it will continue to develop as it did in the last century. It is estimated that they have long been overwhelmed by high-quality and low-cost Japanese goods, and even if they are in the high-end market, they may not be able to keep it.

What Li Yifan didn't expect was that Hu Bin and Yao Chongshan still had such a heart, deliberately set a trick for the Japanese, and then watched how they fiddled with the machine, and the most important thing was to quietly record the methods of others.

After coming back, looking at the assembly craftsmanship of others, the two of them had a good taste and touched it, and then they did it themselves. According to the Japanese method, Hu Bin has always been regarded as a treasured machine. I took it out and reassembled it myself.

I didn't expect it to be such a drum, and the final result surprised the two of them, and the problem of processing accuracy, which had always made Hu Bin feel distressed, did not expect it to be such a simple drum, and it was greatly improved than before.

And the stability of the machine is much better than before, and since then, the two of them have been fascinated by these techniques.

When he first came to Bincheng, Hu Bin was very precious to his machine, and he personally found someone to pull a relationship, built a big truck, and then loaded the machine, and followed him all the way.

After coming, because Li Liqiang was told by Li Yifan, he gave them some scientific research funds from time to time, and these people used these funds to assemble two similar machines.

It's just that this time when assembling, they made certain modifications to their machines according to the development of the 3D printing industry in the past two years and some foreign information they learned.

The whole machine is much smaller than before, the efficiency has also improved a lot, and after they reassembled it like this, the accuracy and stability are also several layers better than before.

Since then, they have been obsessed with how to work out the best assembly solution to minimize vibration and noise.

Don't underestimate such an assembly process, this seemingly simple assembly process is generally the experience of the predecessors who have been tempered and worked the spot.

This is the main reason why the Japanese have always cherished their assembly process, because it looks so simple that you can even understand it at a glance.

But in fact, when people figured it out, it took a lot of effort, for example, the screws in a certain part should be tightened, and then loosened a button, and the screws in another place should be loosened one and a half buckles.

As for why it is so loose and why it is assembled like this, you will never know without thousands of personal tests and inspection results.

In later generations, the 3D printers produced in our country can be said to be almost imported from abroad, from the nozzle to the control circuit board inside.

Then a shell was processed in China and assembled.

However, the same foreign goods, our domestically assembled products, compared with other people's, are not worse than other people's in terms of stability and accuracy.

What is the reason for this? In fact, to put it bluntly, it is because your assembly process and process are not up to the level of others, which is the main reason.

And now Hu Bin and Yao Chongshan, they are not in a hurry to develop new technologies, but are obsessed with the assembly process, the process, can definitely not be said to be not doing business, but is a step to lay a solid foundation, which Li Yifan appreciates very much.

After chatting with Hu Bin and Yao Chongshan for a long time, the more Li Yifan talked and understood, the more he understood, the happier he became, and finally stayed directly in their laboratory for an afternoon.

Seeing that it was not early, Li Yifan planned to let someone come to help them clean up, but Hu Bin said that he didn't let anything, but just let his own people clean up, saying that he was not at ease to let outsiders clean up.

So Li Yifan could only work with them, rolled up his sleeves and did the cleaning work, and after cleaning this side, Li Yifan took them out of the factory and went straight to the city to Harpy.

These people are not very old, Hu Bin has already got married, and most of the others are young bachelors, although everyone is a Frankenstein, but it doesn't mean that this is all, everyone is a science otaku.

Is it still necessary to come out and get in touch with society and improve some lives?

Li Yifan took this group of Frankensteins and went straight to the Zhengyang Hotel at home, ordered a few drinks and dishes, and let the big guys eat and drink, and then took a group of people to sing K and take a bath, anyway, they were obedient to the greeting of these people.

That night, they also let these guys stay directly in their Zhengyang Hotel, which can be regarded as letting these guys enjoy VIP treatment.

The next day, I asked the hotel bus to send them back, and on the same day, I transferred an accountant from the group who my father trusted very much, and went to the laboratory to discuss with Hu Bin how to set up the research institute.

Whether it is still necessary to recruit talents, and how much experimental equipment and work equipment need to be purchased, as well as personal treatment, etc.

The accountant has been working in their family for a long time and is very experienced in this area, and I believe that it should not take long to get started.

In the next two days, Li Yifan also kept running at home and the laboratory, helping with planning and communication, and understanding Hu Bin's needs.

Originally, he wanted to be a hands-off shopkeeper, but after thinking about it, it was a little not good, anyway, he didn't have anything to do recently, so he simply got involved.

After all, it doesn't hurt to know more about a research institute like this, lest in the future, because you don't understand the situation, you will be fooled by the people here.

In just a few days, Li Yifan and Hu Bin have built the general framework of this laboratory.

Because it is a primary start-up stage, and there are not many people who really understand the 3D printing industry in China, Hu Bin absolutely, a small range of recruitment, just recruiting people in a small area, and it is definitely rather scarce than excessive, and those who can be recruited by him must be at the elite level.

And it's better to be the kind of Frankenstein who can concentrate on scientific research, and he doesn't want anything else that likes to get involved, because in his opinion, people who are often distracted because of the world are not good at scientific research.

At present, the scale of the laboratory is controlled at about thirty people, and there are more than a dozen people now, and he and Yao Chongshan still need to find a few people to fill the laboratory.

As for the remaining ten people, it is left to the logistics, administration, finance and other departments.

Anyway, the scale of the institute is not large now, and it doesn't need too many manpower, so he will still help Li Yifan save money.

The structure of the institute was almost built, and Li Yifan also came back from there, and as soon as he returned to the hotel that night, before he could eat a bite of food, he was directly called upstairs by his eldest brother.

And when I came upstairs, in Yang Yuhe's exclusive private room, I happened to see Yang Yuhe talking on the phone with a smile on his face, looking at his current appearance, the sad face some time ago has been swept away, it seems that the thinking of the past two days has made him feel very good, and he has already had a countermeasure.

After a while, Yang Yuhe put down the phone, and then said to Li Yifan with a smile.

"Yifan, I didn't expect you kid, but you are really like a god? Tomorrow, the provincial government will announce that Jin Xiangyun will retire early because of cancer. And the above and the province have also confirmed that I will be sent to the provincial capital in three days, and as you estimated, I will appear as the acting deputy governor this time. If I do a good job this time, in a few months, the agent and the adverb in front of my title will be removed. If it's not handled well, hehe, then don't say it's the previous agent this time, it's an adverb, and it has nothing to do with me......" (to be continued......)
