But after a simple day of cover-up, Koike and his team felt a little disappointed, because they didn't see the legendary laser sintering technology of metal powder, nor did they see what they wanted to see.

But since you're here, let's take a good look at what is desirable about the technology of these Chinese people, and if you come here, you can be safe, anyway, the company also reimburses travel expenses, if you don't enjoy it here, then I'm really sorry for myself.

So after experiencing the initial disappointment, Koike Yifeng discussed with a few colleagues, and finally decided to stay in Hanzhong, stay for a while, and have a good time, after all, they are not the fifty or sixty-year-old old-fashioned Japanese of the last century, and they have no psychological pressure on our company.

But after spending a few days in Hanzhong, it's time to go back, so can't you just go back to the company empty-handed?

I had to bring something back anyway, so Koike Yifeng discussed it with a few colleagues, and then came to the small factory of Professor Hua Guo again.

But this time they put forward a request, that is, they want to see if this 3D printer can process other materials.

However, at this time, this cunning Professor Huaguo began to deliberately behave, but he didn't expect his behavior to arouse Koike Yifeng's curiosity.

In the end, Koike Yifeng was coaxed and lied, and said that several of his companions, but representatives of other manufacturers from Japan, are here to test this 3D printing technology, if your 3D printers here meet their production standards. They may be able to place a lot of orders for you.

And that Huaguo professor is still fragmented. Koike Kazumine certainly knew what was going on. In the end, he simply wrote a check for one million yuan to that guy, and these Chinese people like money, but as long as they like money, it's easy to do.

Anyway, the company will pay for the money in the end, and what I have to do is to give them the information that the company wants to take back and look at it.

Sure enough, after the guy got the check, he immediately smiled. He agreed to all their requests.

After that, it was the current situation, Koike Kazumine and the others took out the resin powder material they had prepared, and then hoped to make a demonstration on the machine of Professor Hua Guo to see if this machine could process such materials.

At the beginning, the guy swore that his machine would definitely work, but the result was a big disappointment, and it didn't work at all.

But the insiders look at the doorway. Koike Kazumine and his engineers watched the entire production process. I don't think it's necessarily so desperate, this machine, if you tinker well, maybe there really is a door.

It's just that the Chinese people have always disliked to study the assembly process, and this machine is really a bit of a tyrannical feeling in their hands.

When the action is up, there is often a creaking sound, which indicates that the parts assembly of the machine must have mismatched parts, and such an assembly seems to be no big deal, but if it is in production, it will lead to the unstable operation of the machine, resulting in insufficient processing accuracy, these are problems.

If you look at the Buddha statue down there, you can see why this is happening.

In the end, Koike Yifeng discussed with a few of his engineers, so he simply rolled up his arms and sleeves, and discussed with the Huaguo professor, saying that they should try to debug the machine and see how it was in production.

The Hua Guo professor simply agreed, after all, he received one million yuan from others, and there was nothing else he could not agree to.

Koike Kazumine and a few colleagues walked to the front of the machine with a flick of their arms, and then everyone began to study.

Fortunately, this is the simplest liquid plastic printing equipment already in Japan, and everyone has come into contact with it before, so it is no stranger to such machines.

Compared with the Japanese-made machine, the layout of this machine made by the Chinese themselves is not very different in some places, but as long as you understand the general working principle, it is not very different.

And this machine after he and a few companions disassembled, can't help but be disappointed, the parts inside the processing is too rough, and even some screws have burrs, and the assembly process is needless to say, such an assembly level, in the eyes of their engineers, is simply the level of primary school students, screwing a screw only knows to screw to death, don't they know, when screwing the screws, to leave a certain amount of return, to ensure that the machinery in the process of processing work, will not produce friction sound because of vibration, As a result, noise is generated because of the problem of wave frequency vibration that affects stability, and accuracy?

These Chinese are really stupid!

Of course, Koike Yifeng wouldn't tell Professor Huaguo about this, but looking at his appearance, he was still looking at the check in his hand, even if he told him, what could he know?

Koike and a few colleagues began to reassemble the machine, and in the process of assembly, in order to ensure accuracy, they also deliberately polished a few parts that they couldn't look at.

And I was very careful when assembling, and I even tried my best to assemble.

Each screw will calculate the margin when screwing, tighten it first, and then loosen the two buckles back, and when the components are assembled together, they will also be specially calculated to leave the margin, and the balance will be left together in the assembly together, so as not to cause the mechanical parts to be displaced due to vibration in the later production and processing process, resulting in problems such as affecting the accuracy of the finished product.

Several people were busy sweating profusely, and they were busy for five or six hours, and then they reinstalled the machine, and after it was installed, they didn't even care about the other party's invitation to invite them to dinner, so they went directly to the professor and began to demonstrate to them again.

Previously, Koike Kazumine and they were not sure whether the reason why this machine failed to process resin powder was because the mechanical assembly was not in place, which affected the processing accuracy.

So this is automatically asked, help reassemble the side, now after their debugging and assembly of the machine, it can be said that it is absolutely in the best state, if in such a state, or the processing of resin powder failure, it means that it is not a problem of processing and assembly at all, but this machine is not suitable for processing powder resin at all.

This is a model product, it is a low-end product that they already have, and they don't need to pay attention to it at all, as long as they get such a conclusion, then their one million is not in vain.

This amount of money is a lot for ordinary people, but for Nikon, which has deep pockets, it is just the price of selling a few more high-end lenses in China.

Hu Bin came to the front of his machine, and when he stood in front of this machine again, he couldn't help but be a little surprised, this is too good, no wonder people have been saying that the assembly process of Little Japan is amazing, and after personally understanding it today, he really can't help but admire.

This machine can be said to have been assembled by him and his team members in the past, but no one is an expert in process assembly, and there are many places where they can't imagine that they need to be assembled like that.

For example, when screwing is tightened, everyone thinks it is best to tighten it, after all, it is safe and stable, but after tightening, loosen the two buckles and leave room for work, which they have never thought about at all.

There is also the installation of several connecting rods, they are really installed according to the data, but when I saw that people are working mechanically, the connecting rod movement and leaving a working margin to ensure machining accuracy, etc., are not what their gang can imagine.

It's no wonder that when the machine was working, it often chattered and rubbed constantly, which sounded harsh, and there was something wrong with it at both ends in three days, and the problem of feelings appeared in this assembly.

Now looking at the machine in front of him, he even suddenly had a new feeling, and after this machine was adjusted by the hands of these Japanese, it seemed that even this momentum was different.

And if you look at the position and angle of the nozzle, and then look at the position, angle, and working margin of the sliding connecting rod, you can understand why the processing accuracy of the other people is so high.

Emotional people have already taken everything into account long before machines start to be used for production, and they have not thought about this before.

Indeed, in Japan, this kind of work is generally discovered by workers working in the field, and then the experience is summed up, and then the engineers solve it.

In China, the workers on the production line are generally coarse, and they do not have such a sense of ownership at all, and they do not go back to summarize these production experiences, everyone is just for a little low salary, after all, workers have no future, there is no room for growth, this is everyone's consensus.

Therefore, different production and living conditions lead to different levels of workers.

And such a problem can never be discovered by Hu Bin and his research team sitting in the office, and today it is these Japanese who have taught them the most vivid lesson.

The machine was shining, but when it started production again, after seeing the results, Koike Yifeng sighed with relief and at the same time...... (To be continued......)
