Hand rubbing nuclear fusion live in the wilderness

Chapter 319 The first country to be tricked

In the spacious dust-free studio, through a side of high-strength and high-transmittance tempered glass, you can clearly see the 'MSC-CNC eight-axis six-linkage CNC processing equipment' inside.

The bottom layer is the shock absorber, which was previously used on the lithography machine.

The area of ​​the shock absorber used on the lithography machine is far less than that of the clean room, but the combination of multiple shock absorbers can still support it.

'MSC-CNC eight-axis six-linkage CNC processing equipment' has certain requirements for shock absorbers, but the requirements are far less stringent than lithography machines.

Multiple shock absorbers are spread on the ground, and a layer of alloy plate is laid on it, and then the numerical control equipment is placed on the alloy plate.

The top-level CNC equipment looks full of technology at first glance, even if it is lying there quietly, it will give people a sense of advanced technology.

In particular, the auxiliary shaft hanging from the alloy pipe on the top of the beam is huge and three-dimensional, and the silver-white metal bottom has a turbine casing-like device.

This device, which looks like a turbine, can ensure that the most important auxiliary shaft among the six linkage shafts can rotate at a parallel angle of 360 degrees, and can also rotate at a vertical angle close to 180 degrees.

These two angles ensure that the tool on the auxiliary axis can contact the surface of the material to be processed to the greatest extent.

Except for this important rotary auxiliary shaft, the other auxiliary shafts are installed on the ground equipment itself.

It is also possible to move forward and backward, to rotate the angle, etc., but due to the limitation of the machine itself, these auxiliary rotation angles and cutting angles are not as large as the first auxiliary axis.

The most important thing is that this 'MSC-CNC eight-axis six-link CNC machining equipment' adopts the line-contact cutting technology.

The so-called line contact processing refers to the processing method in which the tool on the auxiliary axis is formed by line contact during the processing process.

This is the most advanced type of five-coordinate linkage CNC machining technology.

At present, countries all over the world are still studying it, and it has not been fully applied to CNC machine tools.

Only a small number of top five-axis CNC machine tools have applied this technology.

Using this line-contact cutting technology, molding and complex workpieces can be processed in one pass.

Everyone has played with the "four corners" windmills that were folded out of paper when they were young.

This kind of windmill has a certain degree of roundness after the paper is folded out, so almost all CNC machine tools cannot do one-time processing.

Only a very small number of top five-axis CNC machine tools that apply line contact cutting technology can achieve perfect cutting after fixing parts at one time.

If you are not familiar with this, then let's talk about another famous thing.

The vector engines on the top fourth-generation fighter jets and fifth-generation fighter jets, the high-pressure turbine devices, turbine casings and other extremely complex parts are almost all produced after applying online contact cutting technology to top five-axis CNC machine tools .

At present, there are only three countries in the world that can manufacture fifth-generation fighters: the United States, China, and Lao Maozi.

Among them, the country of the United States is in the lead, Lao Maozi is second, and the country of Hua is third.

It has to be said that although Hua Guo has fifth-generation fighters, there is still a big gap with the other two countries.

It can be seen from the fact that the J-20 originally used the Lao Maozi AL-31F engine.

Although it has now been replaced by the domestic Taihang engine, the gap with Su-57, AL-41F and other engines is still not small.

The main reason is that Huaguo does not have a top five-axis CNC machine tool!

That's right, only parts processed at one time by line contact cutting can meet the requirements of the fifth-generation aero-engine.

The highly turbulent and strongly swirling combustion gas in the fifth-generation aerospace engine, as well as the short-lived high-pressure and low-pressure turbine reverse rotation, can only be resisted by one-time precisely processed parts.

For other combined parts, even if you use the most resistant rivets or welding technology for processing, they will not be able to withstand the super strong gas and powerful torque.

But don't worry now.

This live broadcast room brought them a huge surprise.

A 'MSC-CNC eight-axis six-linkage CNC machining equipment' whose performance is no less than or even better than the top five-axis CNC machine tool in the United States, makes people tremble with excitement.

So after getting the news, the higher-ups quickly issued an order to gather domestic top-level high-end CNC machine tool factories such as Yawei, Huadong Heavy Machinery, and Haitian Precision to conduct research and engraving together.

With the efforts of countless scientific researchers and experts for more than two months day and night, the reproduction of the 'MSC-CNC eight-axis six-link CNC machining equipment' has almost achieved synchronization.

That is, when Won assembled the 'MSC-CNC eight-axis six-linkage CNC machining equipment', Huaguo completed the assembly synchronously not too late.

What is missing is the control system of the CNC equipment.

At this point in the reproduction progress, some people are already impatient to verify the accuracy of this CNC equipment.

Although they knew that the anchor would definitely manufacture a central computer and write a control program in the future, they didn't want to wait any longer.

In the eyes of many experts, they have fully controlled the manufacturing process of this CNC equipment. If there is a lack of a control system, then try it with your own.

Huaguo has its own numerical control system. Although it is not as advanced as the American and Germanic countries, the advantage is that it is written by itself and can be customized and modified.

After deliberation, most people agree that they can use their own system to try to control first.

So when Won started to use the lithography machine to manufacture chips, Huaguo also started the customization of the control program for the 'MSC-CNC eight-axis six-link CNC processing equipment'.

The CNC program of eight axes and six linkages is more difficult than the CNC program of five axes and five linkages, but as the world's largest Internet power, Huaguo has countless talents.

With the joint efforts of domestic top engineers, bald-level programmers and other personnel, the NC program for 'MSC-CNC [-]-axis [-]-link CNC machining equipment' is being completed bit by bit.

In the simulated space, nearly three months have passed since the Starlink mission.

That evening, Han Yuan stopped his work because the etching of the last silicon-based chip had been completed.

For nearly a month, he has been using the lithography machine manufactured during the third-level mission to etch and process the chips of the central computer.

Although the millimeter-scale chip is still very weak, compared with the modern nano-integrated chip, it is rubbish.

But the number is superimposed, and in terms of computing power, it can barely approach modern integrated chips.

It has been able to meet the computer control system and 'MSC-CNC eight-axis six-link CNC machining equipment' control program writing requirements.

Being able to do this is enough for him now.

Wait for the control system to be written, and then use the 'MSC-CNC eight-axis six-linkage CNC processing equipment' to upgrade industrial equipment.

As industrial equipment is improved, the precision of lithography machines can be improved again.

This is a path that complements each other.
