Business Empire: There are more than 100 million black technologies

What does this third option mean?

Zhang Hongsheng said that he knew these words, but he didn't recognize them when they were put together.

Unable to understand, Zhang Hongsheng picked up the phone and called the customer service of Yidian Auto.

The call was answered soon.

"Hello, this is Yidian customer service. How can I help you?"

"I just paid the final payment, but in the end there were three car collection options. I understand the first two, but what does the third one mean."

“Well, the third one is unique to our company, our cars are highly modular.

Therefore, all accessories are removable and very easy to learn and install.

The third option is that we ship all the spare parts and frame to your designated delivery location. After receiving it, you can complete all the installation yourself according to the instructions. "

After hearing the customer service's explanation, Zhang Hongsheng said his head was buzzing.

What kind of cool operation is this, allowing consumers to assemble their own vehicles?

Thinking of this, his eyes lit up, this would be more interesting.

You must know that he is a self-media person, and he specializes in vehicle evaluation.

As soon as it was announced that reservations were available, he directly booked a standard version.

He was the first to make a reservation at that time, in order to receive the car as soon as possible for evaluation.

It can definitely get a lot of attention, this is traffic.

You must know that the first few products of Yidian were just released, and the people who reviewed the first batch were as full as they could eat.

Each has gained millions of fans.

If I choose the third option this time, I will be excited to think about the live broadcast of carpooling.

I hung up the phone, directly selected the third option on the web page, and filled in the address of a friend.

His friend sells used cars. The place is big enough for carpooling, and it can also attract traffic to his friend.

A text message arrived soon after, and it arrived three days later.

"Old Sun, in three days, you can make a space for me to use, and I will make a live broadcast."

"No problem, come on, business is not very good during this time anyway, I will help you take pictures then."

Lao Sun has taken many videos of Zhang Hongsheng, so he is no stranger to him and is familiar with the road.

After making the agreement, he hung up the phone.

Zhang Hongsheng didn't say what he was going to do with the venue. It would be more effective if Lao Sun had an accident.

After the first photolithography machine was completed, a lot of chips were produced with a very high yield rate, confirming that the technology was very mature.

So we started to produce the second photolithography machine. We saw that many accessories needed to be polished manually after they were produced.

This kind of efficiency is a bit slow, and the processing accuracy of CNC machine tools needs to be improved.

So a special area was designated in the base, and we began to improve the accuracy of some machine tools and gain relevant knowledge.

These improved machine tools have been able to complete the production of accessories for photolithography machines.

The production and assembly of photolithography machines suddenly became much faster.

Liu Sen did not care about the photolithography machine, but invested in new research. He wanted to develop a high-precision industrial master machine.

Only by completing high-precision industrial master machines can the country's overall industrial processing capabilities be improved.

In this way, he does not need to use gold fingers to modify the machine tools all the time, and can provide the high-precision machine tools of the industrial mother machine production vehicle to other manufacturing companies.

The country also needs it, and so does his own company.

In particular, he needs to improve his manufacturing capabilities so that he can mass-produce satellites, rockets, and even aerospace aircraft.

Otherwise, if the ability is not enough, it will rely on manual polishing bit by bit by experienced and inspected workers, which is too time-consuming.

We don’t know how long it will take for satellites to cover space all over the sky.

Liu Sen uses high-precision machine tools to produce parts one by one, and then uses golden fingers to improve strength and precision again. He uses this to assemble new machine tools, and then produces new machine tool parts again, using golden fingers again to improve lightness and precision. .

This can continuously improve the processing accuracy of new machine tools and save an unknown amount of time.

You need to know that the normal situation is that all the parts need to be polished slowly by hand. One piece may take ten days and a half to polish. After all the accessories are polished, a new one with more precision and smaller production errors can be assembled. machine tool.

This process usually takes half a year or a year.

By cheating, Liu Sen directly shortened the time to a few days to complete a machine tool replacement.

The reason why it takes several days is mainly because it is not only the accuracy of the parts, but also the assembly and adjustment of all spare parts.

Therefore, after the installation of high-precision machine tools is completed, they will generally not be moved or relocated.

And ultra-high-precision machine tools will never be placed in places subject to frequent earthquakes.

As long as a minor earthquake occurs, it will take a lot of time to re-debug.

After several adjustments, Liu Sen used the latest ultra-high-precision machine tools to produce new parts one by one according to the design drawings in his mind.

These parts are completely different from the previous ones.

Liu Sen kept making and assembling large and small parts.

From the initial six-axis linkage machine tool to the 12-axis linkage center.

Then a twenty-four-axis linkage machining center was assembled.

Followed by the 32-axis linkage machining center.

Then to the sixty-four-axis linkage machining center.

Of course, he was not alone in assembling it, there were many people helping to complete it.

Every time one is assembled, everyone smiles one more point.

By the end, everyone was no longer even smiling, but looked blank.

They even wondered if it was an illusion, and the assembly was completed with ease.

Maybe the processing accuracy of these newly assembled ones is average.

Therefore, I was no longer excited, nor did I think too much. I just kept installing the machinery.

Then Liu Sen kept debugging from behind.

After it was finally completed, everyone began to wait for the results of processing.

The results came out soon, and the processing accuracy exceeded ten times that of the original world.

Liu Sen is not too excited about this. This display is still a small machine tool, and it can only process some small parts for the time being.

Liu Sen will later start to build a large gantry machining center, which is the big killer of heavy industry.

Currently, more than half of the top ten precision gantry machining centers in the world are located in Germany.

Half of the first 18 were in Germany.

Machine tools of gantry machining centers are mainly used in automobiles, aviation, railways, engineering machinery, defense industry and other fields.

These large machine tools weigh hundreds of tons and process large parts. Many parts range from several tons to dozens of tons. When processing such large parts, the processing accuracy reaches the micron level.

The top 18 companies are all foreign, but now the 18th company has been acquired by Shandong Guochuang Wind Energy Equipment Co., Ltd., one of the largest foundry companies in China.

The acquired German company specializes in building extra-large gantry mobile boring and milling machining centers.

This type of machining center has a horizontal X-axis stroke of up to 60 meters, a horizontal Y-axis stroke of up to 18 meters, a column spacing of up to 16 meters, a processing height of up to 14 meters, and a load-bearing capacity of up to 1,000 tons.

All of this needs to happen slowly. Now Liu Sen's Guardian Base can produce high-precision machine tools in batches, which can meet many processing needs.
