Because when it comes to large machine tools, you cannot do without the parent machine tool, which is the legendary industrial machine tool.

Many people may not understand what the concept of this industrial master machine is.

In fact, it is a machine tool that can control the machining accuracy of small parts to the limit.

Because large machine tools are actually assembled from such small parts.

For example, if you want to control the machining accuracy of a small machine tool to 2 to 3 wires, it is actually not difficult.

It is rare that you control the parts of a large machine tool to 2 to 3 wires.

This is the most difficult part, so the comprehensive industrial strength of a country is often reflected in these large machine tools.

Because large machine tools are often used in the manufacture of large equipment and equipment such as military industry, large aircraft, gas turbines, aerospace and so on.

The structure of a large machine tool is much more complicated than that of a small machine tool.

Because large workpieces are to be processed, the power that can be exerted and the torque that the machine tool itself can withstand must be taken into consideration.

And in the case of bearing large torque and high torque, ensuring the accuracy of the processed parts is the essence of a large machine tool.

Moreover, a large machine tool requires much more parts than a small machine tool.

In this way, the accuracy of the industrial master machine will be tested even more.

Because only the higher the precision of the industrial master machine, the smaller the tolerance of the processed small parts.

For example, if you have a small machine tool, you may only need 3,000 parts to assemble one.

But if you want to make a large vertical milling machine, you need almost 10,000 parts to assemble one.

As for the two machine tools, you must ensure the machining accuracy of 23 wires. Which one do you think is more difficult?

A small machine tool with 3,000 parts, the tolerance of all parts must be within a certain range, and then the assembled machine tool has a machining accuracy of 23 wires.

For a large machine tool, there are 10,000 parts, which can only be assembled after assembly, and the tolerance must be controlled even smaller to ensure such precision.

This means that a large machine tool uses parts with higher precision than those used on a small machine tool.

even much higher

This is also the main reason why many of our large-scale projects have been engaged in for so many years, but there has been no breakthrough.

For example, aviation development, and gas turbines.

To be honest, don't look at our gas turbine level is still far from the world's first-class

The main thing is its own power, which means how fast your boat can run.

There is also the power increase, which means that a ship of your size can increase its speed to the fastest in a short period of time.

As well as multiple indicators such as fuel consumption, maintenance, and economical use.

If you take all these factors into consideration, you will know the gap between us and the world's first-class gas turbines.

Although many Ermao experts have been invited, it has indeed improved us a lot in terms of gas turbine manufacturing.

But the key point is that the shipbuilding experts like Ermao were not world-class in the first place!

Now the industry knows that you want to process turbine blades for aircraft aeroengines, as well as blades for gas turbines.

Then you have to consider importing machine tools from three countries, one is Switzerland, one is Germany, and the other is Italy!

That's right, these three countries have their own unique skills in the field of manufacturing aviation turbine blades and gas turbine blades.

To put it bluntly, it is the processing of high-speed, high-precision and complex curved blades. The Swiss Mikron can be said to be the king of the kings in this field.

Germany's Siemens has to stand aside

Their machine tools are also key suppliers of well-known companies such as the United States and Luoma.

Our country has recently made a breakthrough in the field of aviation development, and it is also because we have obtained a few second-hand machine tools from them.

Although it is not the top and leading, it does solve some of our pain points.

It's a pity that there are not many of them, and they are not the best machine tools.

Speaking of the price of this machine tool, it is really outrageously expensive, and it can even be said to be outrageously outrageous.

Someone once made an analogy, if they sell their machine tools by the catty, the price per catty is 28 times that of similar products from Dawei Heavy Industry!

Yes, it is that expensive!

And other people's machine tools are open to Western countries.

Even Mao Xiong can get a few back through special channels.

But for us, that f*ck is too deadly stuck.

Even if we are willing to pay twice the price of others, they will not be willing to sell it to us.

To manufacture an aircraft, there are too many machine tools, large and small, that need to be used.

Absolutely not to say that your Xinghuo Technology provides a flexible machining center that can solve all the parts needed on the aircraft.

That's bullshit!

For example, the skeleton of the aircraft and the supporting structure of the wings require large milling machines and drilling machines.

We didn't have these things originally, but in recent years, we have developed a 3-turn-milling integrated machine tool in the field of turning-milling integration.

This can help us solve the biggest problem, and it can even be said that we have directly stepped up to a higher level in the field of finishing.

It was originally a hundred years behind Europe and the United States, but it was shortened to fifty years in one fell swoop.

Moreover, this machine tool is also listed as our country's strategic equipment and is not allowed to be exported.

It's a pity that we only have breakthroughs in this field.

In large vertical machining centers, there are also tape laying machines, wire laying machines, or honing machines for composite materials.

And the field of high-speed cutting of complex curved surface parts, we are still far behind.

It is the gap between these machine tools that separates us from the European and American powers for another fifty years.

Recently, Spark Technology has stepped up its efforts, hoping to make breakthroughs in these equipments that are currently in short supply in our country.

Because of the high-precision flexible processing machine tool, with this thing, we can make breakthroughs in the processing of many small parts.

We can process many parts that were previously processed with insufficient precision.

And after these parts are processed, when assembling those large machine tools, it will get twice the result with half the effort.

Even if the precision of the large-scale machine tools produced is slightly worse than that of the top products in Europe and America, it may be possible to close the gap within ten years, and we can accept it!

Because as long as the gap can be brought down within this range, some countries must be in a hurry.

It was better when the technology was much ahead of us, but now we are about to catch up.

They won't be defending anymore, that's right.

Take this chip for example. We used to be able to produce 90 nanometers, and the self-produced lithography machine is also at this level.

So you see, they don't even sell us the technology and equipment of 28nm chips used in cars.

But some time ago, there was a rumor that we are about to make a breakthrough in the field of lithography machines, and we will soon be able to produce our own 28nm lithography machines.

You can see that some companies immediately let go, and they want to build a 28-nanometer chip production plant in China, and they need to increase investment.

Anyway, if you can't produce it yourself, then I won't sell you the equipment, only the finished product.

But once you can produce your own equipment, then I will sell my equipment to you at a cheaper price, or even pack it up, and sell it to you at a discount.

The purpose is to crush your own R&D department, so that he can't make money, and has no money for R&D.

Those European and American companies have tried this method countless times, and most of the time they have been tried and tested.

Indeed, many domestic R&D institutions have been cheated. It's a pity that someone is fooled every time.

And Japan is the same, they can be said to be the gatekeeper in the field of intermediate finishing products.

Once we have made a breakthrough in the field of precision machining, they will be the first to be unlucky.

Because their technical background, after all, is not as deep as that of Western countries.

Even in the field of the electronics industry chain, they are indeed very advantageous in certain single products.

But in fact, they are still brothers in terms of machinery.

In the field of small and medium-sized general-purpose commercial machine tools, they can sweep the world with their cost performance.

But if they really enter the field of high-end machine tools, they are the younger brothers.

You can go to Mitsubishi Heavy Industries' equipment production line, which machine tools are used?

Qing Yishui, Cincinnati, USA, and M Torres Machine Tool, Spain.

Many people may have never heard of these machine tool manufacturers.

As far as the general public is concerned, they may hear more about the familiar Japanese machine tool companies such as Yamazaki Mazak, Fanuc, Jetco, and Dawei Heavy Industries.

That's because these companies can indeed sweep their competitors by relying on cost performance in the field of producing small and medium-sized general-purpose machine tools for civilian use.

But if you enter the field of real high-end machine tools, such as aircraft manufacturing, military industry, gas turbines, or large optical lens grinding and other fields.

Machine tools that sell well in these fields are basically European and American products.

And these European and American machine tool companies, because their products are directly supplied to upstream manufacturers, so ordinary people generally rarely know about these machine tools.

Even their names are rarely heard.

Are you like Cincinnati in the United States?

Many people may know that this is a place name in the United States, but who knows that this is a very famous machine tool manufacturer in the United States?

Speaking of this machine tool factory, many people may not know their status in the world.

Because this company is the originator of the world's first five-axis CNC machining center, and they were the ones who built the world's first five-axis CNC machine tool.

Later, they also transferred the technology of the CNC system to Japan, which made Japan's FANUC.

The machine tools of this company are currently mainly supplied to aircraft manufacturers such as Boeing, Luoma, and Dassault in France.

So it is naturally difficult for ordinary people to know the existence of such companies, because they have been hidden at the top of the technology crown!

But what we have to do now is after we have a real high-precision master machine.

Then we will produce those large-scale high-precision machine tools that we have been lacking in the past, as if the real peak of science and technology is very close!
