And this minivan is not the kind of minivan that is commonly driven by people.
And more like a smart minivan in the shape of a centaur, the front cockpit is more like a robot.
After he arrived at the designated location with the cargo, he actually stretched out a few mechanical arms from both sides of the cargo box and began to unload the cargo by himself.
At the same time, there are many robots in the shape of trash cans, constantly walking between various shelves.
Sorting and placing various materials.
During the whole process, no one was seen.
Everyone who watched this scene opened their mouths wide open. To be honest, it wasn't that this scene really happened right in front of our eyes.
They even thought that this was an American shooting a sci-fi movie.
After the car stopped in the designated area, the representative of Quanye Fund led everyone out of the car.
But he didn't directly take everyone into the conference room to meet the engineers who had agreed before.
Instead, I took everyone around the factory area and visited some projects that can be opened to the outside world.
What surprised Huang Haibin the most was that in a production workshop, he actually saw the kind of mechanical arm he used on surgical robots.
It's just that these robotic arms are much more advanced than the ones he used on surgical robots.
These robotic arms are fixed on a platform.
There are four arms in total, two of which are mechanical arms, holding an iron ingot to be processed.
The other robotic arm, holding a milling cutter, continuously processes turning and milling on the iron ingot.
The other robotic arm holds two pipes and continuously sprays liquid into the processing area to ensure that the processing area can be effectively cooled and lubricated.
During the processing, the two fixed mechanical arms will constantly adjust the angle of holding the iron ingot.
One is to make it easier for the mechanical arm responsible for turning and milling to process in the working area of the iron ingot, and the other is to buffer the impact brought by the processing...
Such a scene can be said to have stunned everyone present.
Everyone couldn't help but stopped and began to quietly appreciate the processing process.
Because the technological content contained in this processing process is understood by everyone on site.
Some people even lost control of their emotions as soon as they saw this.
If this processing mode is really successful, it means that in the field of machining, we will no longer be stuck by Europe, America and Japan.
It can even be said that we have opened a new chapter and completely opened a new field of finishing.
As we all know, in the field of machining, especially finishing, our country has always been far behind the world's top powers.
However, there are only three real industrial powers in the world in the field of machining.
The first to bear the brunt is naturally the United States, followed by Germany and Japan.
Many people may say that the United States also counts? Aren't the machine tools in the United States imported from Germany and Japan?
In fact, if you really think so, then you are dead wrong.
In fact, when it comes to machining, especially the field of precision machining, it is not an exaggeration to say that the United States is the most powerful.
Japan and Germany are only better in terms of finishing for daily use.
Their machine tools are indeed very good in this regard.
But if we talk about the field of finishing of large parts, we must talk about the United States.
For example, the wing and fuselage of the B2 stealth bomber in the United States, the kind of one-for-one finishing technology, can only be achieved by the United States in the world.
There are also certain large parts of spaceships and rockets, which only Americans can complete.
As for Japan and Germany, their machine tools are indeed very good in the field of machining that we use every day.
Japan's Dawei Heavy Industry, Makino, and their ace Yamazaki Mazak, Germany's DMG, Siemens, etc., are all benchmark companies in the field of machine tools.
And our country, in this respect and these world powers,
That gap is not a star and a half.
Now the general machine tool market in our country is basically monopolized by Japanese and German machine tools.
And don't look at people selling you machine tools, but if you want to use this machine tool for other purposes, that's impossible.
For example, they have installed a positioning system on the machine tool. If you want to move the machine tool, it will be locked.
In addition, the machine tool can only process some workpieces approved by them. If you want to process some parts related to military use, you will also be locked by them.
So more than ten years ago, our military equipment has always shown a situation of being big but not strong.
This situation was not alleviated until two thousand years ago.
It was also at that time that we obtained a batch of top-level five-axis linkage machine tools through a neutral country in Europe, which relieved our country's troubles in the finishing of military weapons.
In addition, later on, we had some technological breakthroughs in the field of 3D metal printing.
So later, a certain 20 was born.
However, because the number of those machine tools is really limited, our annual output of a certain 20 is still not up to now.
Compared with the Mao Bear in the United States, who can storm soldiers at any time, we are still a little far behind.
The root cause lies in our machine tools.
Some people may say, isn't it just a machine tool?
If you go to foreign websites, you can find blueprints of other machine tools on the Internet. What's the problem?
Hey! That's the truth, people really dare to put the drawings of these machine tools on the Internet, but even if you have the drawings, you can't make them.
On the one hand, it is because we are far behind others in terms of materials.
On the other hand, in terms of skilled workers, we are really far behind others.
First of all, let’s talk about materials. To be honest, our domestic machine tool companies have one thing to say, and they can’t even make a machine tool stand and a fixture for fixing workpieces well.
I believe that as long as you have been in contact with machining companies, you will have a deep understanding of this point.
Why can't even the jigs and benches be done well.
Because the jig and stand seem simple, but actually have very high requirements for materials.
Just like a bench, it must have a very strong impact resistance, and the requirements for hardness and toughness are also very high.
The most important thing is that there should not be too much stress inside, because if the stress is relatively high, then the processing will be successful.
When the tool exerts force on the workpiece, it is transmitted to the stand, and the stand not only cannot effectively evacuate the force, but also generates a reaction force, which returns to the processed workpiece.
Thus affecting the precision of processing!
However, machine tool factories in countries such as Japan and Germany will take various stress-relieving measures for the metal materials of the bench when producing the bench.
For example, it used to be placed in a natural environment, but later there were technical means such as degaussing and heat treatment, which greatly accelerated this speed.
So their bench production efficiency will be higher.
On the other hand, it is the fixture, which seems to be a very common fixture, but actually has very high requirements for strength and toughness.
And it is the same as the bench, they are all parts that need to remove internal stress.
And these two parts are actually the parts with the lowest technical content in modern five-axis linkage machine tools.
But even such parts, we can't do well.
As for the more difficult processing tools, ball screw bearings, and servo motors, as well as CNC systems, etc., let alone.
Speaking of this, some people will definitely say, you are all nonsense, this is all news hundreds of years ago, and now we have already caught up.
Hehe, hearing this, scientific researchers like Li Wensong and Huang Haibin, who are often in contact with front-line production, really want to hehe these stupid faces.
These people must have watched too much, and their minds are full of mud.
In fact, if you have really come into contact with the front-line factories and the workers who are actually producing on the front line.
Then you will know how big the gap is between us and Japan and Germany in the field of machine tools.
Domestic machine tools seem to be similar to foreign machine tools, but they can be used for more than ten years without breaking down.
As for our machine tools, accidents continue every day for only one month, and we have to find a dealer for maintenance every day.
It seems that the price is indeed cheaper than foreign equipment, but it is really troublesome to use. The later maintenance, coupled with the delay in the construction period, absolutely any owner will hate these machine tools.
In fact, the gap is first reflected in the material.
Not to mention the benches and fixtures of other machine tools, but when it comes to cutting tools and ball screw bearings, we are even farther behind in materials in these aspects.
To put it bluntly, the only difference between us and many foreign companies is in material science.
And materials, in fact, are the most basic places of all modern sciences.
But look at our domestic college students who study biochemical and environmental materials, what happens after graduation.
It is not an exaggeration to be unemployed after graduation, because there are not many companies in our country that are seriously engaged in material research and development.
Because the research and development of materials requires a lot of real money!
If you don't believe me, just look at how many steel companies we have in my country, but now the special steel that our country needs every year actually needs to be imported from Japan.
Not to mention the special steel for warships and aircraft, they will definitely not sell it to you.
For example, to build high-rise buildings, we need to import special angle steel and girders from Japan.
Because our domestic steel is not a little bit worse than others in terms of tensile strength and corrosion resistance.
This is the gap in materials.
Especially in the field of steel, if you want to research special steel, then you need to invest real money in it.
Smelting molten steel one furnace at a time, if one furnace cannot be fired, you have to fire another furnace.
And the molten steel in this furnace, not to mention the amount of iron ore powder used, is the electricity, coke, and various catalysts used in the refining process, and there are two kinds of additives.
It will cost hundreds of thousands or even millions of dollars once it is fired. How many domestic companies are willing to spend money on it?
