After dinner, Chen Xu and Fan Qing went out for a walk.

I didn't go far until I passed the barbecue tower and walked up the stairs.

When I got to the top, I found that there were three residents of the community who were enjoying the coolness, talking softly in the direction of the riverside.

Chen Xu walked to the side, holding on to the wooden railing, the breeze was blowing, and he looked up at the sky.

The night is clear tonight, and a bright moon hangs high in the deep night sky, sprinkling a faint brilliance, which is very beautiful.

Chen Xu looked at the moon for a while, then lowered his head and looked at the little sparks on the riverside and asked, "What major did you study in college?"

Fan Qing's information Chen Xu knew everything clearly, and even Fan Qing himself couldn't remember the things clearly, he also remembered it, but now he just asked casually.

Fan Qing, who was standing on his left, immediately replied, "Electrical automation." ”

"How's it going, in the United States?"

"Also... Yes. ”

"If it weren't for that incident, when would you go back to China, or would you stay in the United States?"

"Yes, maybe stay in the United States! You know, my parents are both drifting north, although they barely stayed in Kyoto, but in fact, except for a house, there is nothing else, there is no money, no one wants people, if I return to China, everything will have to start from scratch. ”

"Hmm!" Chen Xu responded, but he thought of some problems encountered in the realization of China's electrical automation, and then thought of high-precision CNC machine tools.

Xinghai Technology Precision Manufacturing Department has been researching nano-scale industrial machine tools.

Industrial machine tools include CNC machine tools, EDM machines, wire cutting machines and water cutting machines, etc.

They are mainly divided into two parts, one is the electronic system and the other is the mechanical system.

The electronic system also includes: numerical control system, drive system, motor, chip, vision system, and turntable, servo tool magazine and other mechatronics components.

The mechanical part includes: machine tool mechanical structure system, tool magazine structure, guide rail screw, actuator, protective device and so on.

Xinghai Technology has solved 90% of the core technology, and now the motor is left.

It's not easy.

The core problem of the motor is the ultra-precision nano-encoder, and the ultra-precision nano-encoder involves ultra-precision chips, and high-precision lithography machines and other equipment are required to create ultra-precision chips.

The production of such high-precision equipment must be high-precision CNC machine tools and other industrial machine tools and measuring equipment, which is a spiral cycle upgrade system with continuous improvement of progressive accuracy.

He now lacks a slow-wire EDM machine with nano-level machining accuracy, which is the only one in the world that Sodick has in Japan, and it is the only one.

But the problem is that Sodick doesn't sell, no matter how much money he gives, he hates it so much that he really wants to hire a bunch of mercenaries to grab it.

The little Japanese devil is really good at precision machining.

The world's most accurate machine in the field of ultra-precision machining is the AHN15-3D free-form diamond processing machine from JTEKT, which is mainly used for ultra-precision turning and grinding of various optical lenses and blue light lens molds.

Its machining accuracy is nearly 8 times higher than the world's most powerful military machine tool LLNL's LODTM and DTM-3, and the OAGM2500 of British CUPE.

The world's highest-precision machine spindle comes from Nippon Seiko.

70% of the world's precision machine tools are equipped with the world's most high-precision micron-level automatic tool setting instrument developed by Metrol.

The spindle speed of benzene has developed to a maximum of 4000~5000r/min, while the domestic spindle speed mainly hovers at 1000~1500r/min.

Four of the world's top ten CNC machining center brands are Japanese benzene enterprises.

However, the little Japanese devils are also very bad, they all keep the best products for their own country, and sell some obsolete products or production lines abroad.

Like mobile phones, Sony, Panasonic, and Sharp were very popular back then, why are there only three major players left in the world now?

It's not that Japanese benzene technology can't work, or that the R&D capabilities can't keep up, but that Sony, Panasonic, and Sharp always sold the latest products in their own countries and sold the backward products of the previous generation abroad, which made their reputation stink.

Later, when the rapid rise of mobile phone manufacturers in Hanguo, Mi and China, Japanese mobile phone manufacturers completely went to play.

Then there are other electronics, beauty, automobiles and other products, compared with the products sold locally in Japan, both in terms of materials and design, they are a grade off!

This is the inferior root nature hidden in the bones of the Japanese people!

……

Chen Xu was chatting with Fan Qing for a while, thinking about it at the same time, how could he buy, cheat, or snatch the nano-level slow wire EDM from Sodick?

Before an hour passed, Chen Xu and Fan Qing went down the stairs.

The three people who were enjoying the cool air on the tower also went down together, two men and one woman.

A man in his fifties, a teenage high school girl, a little boy of seven or eight years old.

Chen Xu and the older man were behind him, and they talked to each other a few words by the way.

The people who can live in this community are not ordinary people.

Really.

The man's name is Chang Penghai, the owner of a listed company in China Shipping, this company is mainly engaged in precision machinery manufacturing, with annual sales of more than one billion, and has a certain reputation in Jiangsu, Zhejiang and Shanghai, and has business dealings with Xinghai Technology.

And the two young men and women in front of him were his sons and daughters,

"The real industry is not easy to do, don't look at our high sales, in fact, R & D costs, manufacturing costs, and sales costs account for more than 90%. You may not believe it, our company had sales of 1.7 billion last year, but the profit was less than 20 million. ”

After a pause, Chang Penghai said, "I plan to retire in two more years." ”

"yes, why?"

"One is that I can't fight, and the other is that I don't want to fight. ”

"Hehe......"

The two of you talked to the bottom of the tower one by one, and Chang Penghai asked with a smile at this time: "What are you doing? Are you still studying?"

Although Chang Penghai didn't know Chen Xu, he didn't dare to look down on him at all.

The people who can live in the riverside garden villas are either executives of the world's top 500 companies, or the owners and directors of listed companies, or their children.

Chen Xu laughed and said, "Artificial intelligence research." ”

"Artificial intelligence?"

"Uh, Xinghai Technology. ”

"Oh, Xinghai Technology?" Chang Penghai was a little surprised, and then smiled: "That's really a coincidence, our company has business dealings with your company." ”

"I know. ”

"You know?"

"That's right. Xinghai's purchase volume in your company has reached 700 million this year, and it should be your largest customer!"

Chang Penghai was surprised again.

Although their company is a listed company and will disclose its business situation, such as the specific sales targets and sales details, this is a trade secret and cannot be casually announced.

But a person I met on the road actually knew that this was a little unusual.

"You are ......"

"Chen Xu!" Chen Xu said with a smile, then stretched out his hand and pointed to the villa in front of him, "That's my house, I have time to play." ”

After speaking, Chen Xu left with Fan Qing.

Chang Penghai waited for Chen Xu to walk out of a distance before he realized who Chen Xu was, slapped his palm fiercely, made a crisp sound of "pop", and said excitedly: "Ouch, hey, this thing is ...... trouble"
