I have opened a new book: Global Apocalypse: My house can be upgraded. Brothers, please help me collect it and give me some recommendations!

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

Many people may not understand what this industrial mother 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 with such small parts.

For example, it is not difficult for you to control the processing accuracy of a small machine tool to 2 to 3 wires.

But it is rare that you control the components of a large machine tool to 2 to 3 wires.

This is the most difficult part, so how strong a country's comprehensive industrial strength is actually often reflected in these large machine tools.

Because large machine tools are often used in the manufacturing of large-scale equipment and equipment such as military industry, large aircraft, gas turbines, aerospace, etc.

The structure of a large machine tool is much more complex 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 account.

When bearing large torques and large torques, ensuring the accuracy of processing parts is the essence of a large machine tool.

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

This will test the accuracy of the industrial master machine even more.

Because only the higher the accuracy of the industrial master machine, the smaller the tolerance of the small parts produced.

For example, a small machine tool may only require three thousand parts to assemble one.

But if you want to build a large vertical milling machine, you need about one thousand parts to install one.

For both machine tools, you must ensure the processing accuracy of 2-3 wires. Which one do you think is more difficult?

Small machine tools, 3,000 parts, the tolerances of all parts must be within a certain range, and the machine tools assembled have a machining accuracy of 2-3 wires.

Large machine tools have 10,000 parts, which can only be assembled after being assembled. The tolerances must be controlled smaller to ensure such accuracy.

This means that the parts used by a large machine tool have higher accuracy than those used on small machine tools.

Even much higher...

This is also the main reason why many of our large-scale projects have been working on for so many years but have not made any breakthroughs.

For example, aviation engines and gas turbines.

To be honest, don’t look at the level of our gas turbines that are far from the best in the world…

It mainly depends on your own power, which means how fast your ship can run.

There is also liter power, which means that your ship is as big as you can increase the speed to the fastest in how short it takes.

As well as multiple indicators such as fuel consumption, maintenance, and usage economy.

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

Although we have hired many Ermao experts, we have indeed improved a lot in gas turbine manufacturing.

But the key is that Ermao and other shipbuilding experts are not world-class!

Now the industry knows that you want to process turbine blades of aircraft aircraft and gas turbine blades.

Then we need 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 manufacturing aeroengine turbine blades and gas turbine blades.

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

Siemens, Germany, has to stand aside...

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

Our country has recently made breakthroughs in the aerospace industry because we have gotten a few of their second-hand mobile beds.

Although it is not the top and the most advanced, it has indeed solved some of our pain points.

Unfortunately, there are not many, and it is not the best machine tool for others.

When it comes to the price of this machine tool, it is really expensive, or even outrageous.

Someone once made an example. If their machine tools are sold by kilograms, the price per kilogram is 2.8 times that of similar products of Dawei Heavy Industry!

That's right, it's so expensive!

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

Even the Mao Bear can get a few of them through special channels.

But for us, it's so stupid.

Even if we are willing to spend twice the price of others, we are not willing to sell it to us.

There are more machine tools to use in large and small manufacturing aircraft.

It definitely doesn't mean that if you provide a flexible machining center, you can solve all the parts needed on the aircraft.

That's nonsense!

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

We didn't have these things at first, but in recent years, we have developed a 3D turning and milling integrated machine tool in the field of turning and milling integration.

This has helped us solve the boss’s problem, and it can even be said that we have taken a step forward in the field of finishing.

It was originally one hundred years behind Europe and the United States, but it was shortened by fifty years.

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 composite tape laying machines, wire laying machines, or honing machines.

We are still far from the field of high-speed cutting of complex curved surface components.

It is the gap between these machine tools that has opened us up with European and American powers for another fifty years.

Recently, Starfire Technology has increased its efforts in the hope of making breakthroughs in the equipment currently in short supply in our country.

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

We can process many parts that were not well-processed in advance.

After these parts are processed, the results will be achieved with half the effort when assembling those large machine tools.

Even if the large machine tools produced have slightly worse accuracy than those of the top European and American goods, we can still accept the gap within ten years!

Because as long as the gap can be reduced within this range, some countries will definitely be anxious.

Originally, the technology was much better than us, but now we are about to catch up.

They won't be on defense anymore, it's true.

For example, this chip was able to produce 90 nanometers in the past, and the self-produced lithography machine was of this level.

So you see, they don’t even sell us the technology and equipment of the 28-nanometer chip used in cars.

But some time ago, there was a news here that we were about to make a breakthrough in the field of lithography machines and would soon be able to produce 28nm lithography machines.

You see, some companies immediately let go and want to build a 28-nanometer chip production factory in the country and increase investment.

Anyway, if you can't produce it yourself, I won't sell it to you, I will only sell it to you finished products.

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

The purpose is to squeeze out your own R&D department so that it can’t make money and do no money in R&D.

This trick has been done by those European and American companies many times back then, and most of the time it has been tried and tested.

It has indeed deceived many domestic R&D institutions. Unfortunately, people are fooled every time.

The same is true in Japan, they can be said to be goalkeepers in the field of intermediate finishing products.

Once we make a breakthrough in the field of precision processing, the first one that is unlucky will be them.

Because their technological background is not as profound as Western countries.

Even in the electronics industry chain, they do have very advantages in certain single products.

But in fact, they are still younger brothers in the mechanical field.

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

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

You can go and see which machine tool is used on Mitsubishi Heavy Industries’ equipment production line?

Qingyishui, Cincinnati, USA, and Mtorres machine tools in Spain.

Maybe many people have never heard of these machine tool manufacturers.

For Volkswagen, I heard that more may be familiar Japanese machine tool companies such as Yamazaki Mazak, Fanak, Jetco, and Dawei Heavy Industry.
