Alien Industrial Tyrannosaurus-Rex

"Mr. Tawu..."

"Please speak."

"Our machine tools all have coordinate projections."

"What do you mean?"

"There are restrictions on the place of use. It cannot exceed the specified coordinate range. For example, it can only be used in your South Africa. If it exceeds this range, the machine will automatically lock."

"No problem. We use it in our own homeland."

"it is good."

Wang Bu'an nodded.

It seems that Tawu is indeed sincere.

The so-called coordinate projection is not bragging. It is a genuine existence.

Why can't other robot elves leave the industrial park for half a step except for Robot Elf One? Just use coordinate projection! Limit their scope of action.

Such good restrictive measures must of course also be used on the machine tool. To ensure that the use of the machine tool is not prohibited.

Otherwise, it would be no fun if Tawu sold it to a third country.

In fact, many high-end machine tools have positioners.

The main role is to supervise the users of machine tools.

If it is an attempt to resell the machine tool to a third party, the manufacturer will know immediately.

"In addition, there are certain protective measures."

"What does that mean?"

"It just cannot be completely disassembled. If there is a problem, please return to the factory for free replacement. You cannot disassemble it yourself."

"But, ordinary maintenance..."

"Of course there is no problem with ordinary maintenance. Complete dismantling will involve technical secrets."

"no problem."

After Tau hesitated for a moment, he finally agreed.

This is also expected.

There are restrictions on precision machine tools imported from any country.

Among them, the most important one is that it cannot be dismantled. Otherwise, it is a violation. If problems occur in the future, the supplier will refuse to repair.

Strictly speaking, the main purpose of this provision is to protect core technology secrets.

Especially for five-axis CNC linkage machine tools, the core secrets are very precious.

In addition, the disassembly of the machine tool will seriously affect the accuracy.

Once disassembled, the accuracy of most machine tools is difficult to guarantee.

"The accuracy you need is a bit high!"

"I also ask Mr. Wang to help me vigorously."

"Ha ha."

Wang Bu'an did not answer directly.

The precision of the machine tool Tau needs is indeed very high.

All accuracy requirements are 1 micron.

Obviously, this is a reference to the most advanced machine tool parameters produced in the industrial park.

In fact, looking around the world, there are almost no machine tools capable of 1 micron accuracy. Almost all are laboratory products.

Only Wang Bu'an's machine tools can be used on a large scale.

Perhaps this is the key reason why Tawu came to find himself.

Some machine tools that claim to be able to achieve 0.01 micron accuracy are actually confusing concepts.

What is 0.01 micron? 10 nanometers!

It is more advanced than Intel's processors.

Other people's processors were carved out with lithography machines.

In fact, Wang Bu'an can also do such a machine tool. 1 nanometer can do it. What's more, it is 0.01 microns.

However, such a machine tool is useless for most parts.

Unless it is used to produce electronic products or optical components.

For mechanical parts, 1 micron is already very high and very high precision.

"Geometric accuracy, 1 micron."

"Motion accuracy, 1 micron."

"Transmission accuracy, 1 micron."

Wang Buan muttered to himself thoughtfully and slowly put down the purchase list.

There is no problem with the indicator parameters. Can do it.

The issue is……

Can Tawu and his workers really use such high precision?

It's not that he underestimated Africans. I am really worried!

When it comes to construction, don't count on Africans.

But when it comes to sabotage, no one is an African opponent.

No matter how advanced the instrument is in their hands, it can turn you into scraps of copper and iron. This is an innate talent attribute of the African black uncle.

Sometimes, Wang Bu'an felt that a machine tool with a precision of 1 mm was enough.

The accuracy of the machine tool has three aspects:

Geometric accuracy.

Movement accuracy.

Transmission accuracy.

Geometric accuracy refers to the accuracy of the shape, mutual position, and relative movement of the main components when the machine tool is unloaded without moving (the machine spindle does not rotate or the table does not move, etc.) or when the motion speed is low. Such as the straightness of the guide rail, the radial runout and axial movement of the spindle, the parallelism or perpendicularity of the spindle center line to the moving direction of the sliding table, etc. Geometric accuracy directly affects the accuracy of processed workpieces, and is the basic index for evaluating the quality of machine tools. It is mainly determined by the quality of structural design, manufacturing and assembly.

It is also called static accuracy and static accuracy.

It is the most basic indicator of machine tools.

Most of the time, when referring to the accuracy of a machine tool, it means static accuracy. It is the easiest accuracy to achieve.

The question is, does Taou understand?

"Mr. Tawu, do you know what geometric accuracy is?"

"do not know."

Sure enough, I didn't know at all.

Still very calm.

I am really worried for future machine tool users!

Are they really useful?

"Mr. Tawu, do you know the accuracy of the movement?"

"do not know."

"Then do you know the transmission accuracy?"

"do not know."

Wang Buan smiled secretly.

You see, this is the result. They don't even know the concept of accuracy.

The parameters on the purchase list are probably copied.

Seeing how others wrote, Tawu copied it.

Motion accuracy refers to the accuracy when the main parts of the machine tool move at the speed of the working state. Such as the rotation accuracy of the high-speed rotary spindle. For high-speed precision machine tools, motion accuracy is an important index to evaluate the quality of machine tools. Motion accuracy and geometric accuracy are different. It is also affected by moving speed (rotation speed), gravity of moving parts, transmission force and friction. It is related to factors such as structural design and manufacturing.

Make a big cross first. Indicates that the African black uncle does not understand.

If you don’t understand, you have to send a technician.

However, Wang Bu'an has no technicians.

How to do?

Had to find foreign aid.

Can't send robot elves over, right? It will be scary.

Then, make another big cross.

Transmission accuracy refers to the coordination and accuracy of the relative movement between the end-effectors of the machine tool transmission system. The error in this aspect becomes the transmission error of the transmission chain. For example, when the lathe is turning the thread, the movement of the tool post should be equal to the lead of the dry thread for each revolution of the spindle. But in fact, due to the error in the transmission chain between the spindle and the tool post, the actual displacement of the tool post and the error are the transmission error of the threaded transmission chain of the lathe. The transmission accuracy is determined by the design of the transmission system, the error of the ideal shift distance, and the manufacturing and assembly accuracy of the transmission parts.

African uncle black doesn't even understand the accuracy of motion, so don't mention transmission accuracy.

This is the essence of high-end precision machine tools.

It is also the core secret.

In this part, technicians can't guarantee it.

why?

The technology involved is very deep.

Basically, if there is a problem with the transmission accuracy, it needs to be returned to the factory for adjustment.

Of course, Wang Bu'an doesn't need it.

He is very confident in the technology of Cybertron.

Others can even produce a hydraulic press of 50 billion tons. Is there a problem with a machine with a precision of 1 micron?

Just this way...

Not only to sell machine tools, but also to sell technicians and training courses!

Basically, it is to teach by hand. When necessary, you may need your own technician to operate it yourself. So that Uncle Hei often manipulates it, and it will be broken in two hits.

Even the technology of Cybertron can't stand man-made damage.

But Uncle Black is still a master of destruction.

Wang Bu'an suddenly sighed that advanced Western countries refused to sell precision machine tools to Africa. Perhaps it was not all because of the technological blockade?

Maybe it just feels that such a good machine tool is broken by you. It is really heartache!

"Do you want to reject him?"

"What a dilemma!"

There were countless thoughts in Wang Bu'an's mind. He has no experience in such things.

It seems that if you have time, you should consult Cheng Kailong.

Perhaps he can provide some suggestions.

Fang Yuqing peeped at Wang Bu'an quietly.

Doesn't seem to be a liar.

It doesn't seem to be acting?

They seem to be discussing technical details seriously.

She couldn't help feeling secretly.

In this era, you have to require technology to eat soft rice!

That Lu Lingqi is definitely a strong woman. Want to eat her soft rice, where is it so easy?

Wang Bu'an also secretly sighed ~www.wuxiaspot.com~ When did he actually have the ability to influence a country's industrial development system?

The machine tool is indeed an industrial master machine!

As long as you want to develop industry, you must use machine tools.

Look at your belief value.

There are already more than eight million. There is still more than one million short.

Tawu’s arrival was like having gotten a hint from God in advance and he had booked in advance.

The point is, this is a very good start.

What can be more fulfilling than building a complete industrial system?

In the future, other countries only need 15 billion U.S. dollars to establish a relatively complete industrial system. Never ask for help.

This is simply bad news for some Western powers.

They have always relied on the scissors gap to exploit backward countries.

Industrial products are where the biggest export profits are.

However, once there is a small and complete industrial system, many key industrial products can be produced by itself.

This is tantamount to cutting off the markets of certain Western countries.

Do they stand on the sidelines?

Will they really tolerate such a procurement plan?

"Mr. Tawu, I feel that your procurement plan will definitely encounter great resistance. It may not be successful." Wang Buyan said bluntly.

"We only discuss technical issues." Tawu said slowly.

"There is no problem with technology. There is no problem with price. I can provide all the machine tools you need."

"Okay. Thank you so much! Shall we sign a cooperation agreement?"

"it is good."

Tau immediately took out the documents.

Of course he came prepared. The corresponding documents have already been prepared.

signature.

Exchange signatures.

confirm.

The contract officially came into effect.
