At noon, the group started in the company canteen, and the young managers and supervisors who signed up collectively went to get a haircut and buy clothes. Pen ~ fun ~ pavilion www.biquge.info

When he went to work in the afternoon, Ye Qing was surprised to find that these guys, who were originally unkempt, had become well-dressed and radiant one by one.

Even Ji Ke, the most technical nerd, also cut a pompadour hairstyle and paired it with a brand-new Burberry cashmere trench coat, which made Ye Qing almost mistakenly think that a star had touched the wrong door.

The two captains of the security department, Wu Yuexiang and Zhang Haoxuan, also signed up.

They changed into plain black fur-collared leather jackets and high-top combat boots. If this dress falls on ordinary people, most of them will be mistaken for a gangster who watches the scene. But when worn on them, it looks particularly heroic.

Both of them are professional soldiers trained by the army, and they have a particularly masculine aura.

Ye Qing was a little speechless, how could these guys be like wolves, when they heard that there were beautiful women, they were more active than receiving salaries?

The party time was set at eight o'clock in the evening, and it was still early, Ye Qing drove back to Longxi Beach, ready to take the finished screws to Zhongyun University.

The manufacture of the screws was placed opposite Ye Qing's office in the factory. There is a non-standard product production room, which has the most complete precision processing equipment in the whole factory.

Walking in, there is only one delicate master sitting at the workbench busy with something.

"Where's the screw?"

The delicate master, who was sitting intently next to the industrial microscope, pointed to a sealed plastic bag on the workbench: "In the bag, the processing technology of that nut is still good. I have tested it, and between its 300 threads, the positive and negative errors are all controlled below 80 nanometers. ”

"It should be made with an industrial mother mechanism that specializes in processing high-precision lead screws, and its own material is also good, with a hardness of 6.5 on the Mohs scale. ”

It is more difficult to make the master of ingenuity praise a good sentence than to win the Industrial Science and Technology Award.

So Ye Qing asked the master of ingenuity curiously, how did he make these screws?

As far as Ye Qing knows, there is no industrial machine that can process this kind of screw in the Longxitan factory.

The Japanese University of Science and Technology is looking for an industrial machine, and a country may only have a few treasures.

The high-precision lead screw is the core component of the five-axis machine tool used to ensure accuracy. It can process high-precision lead screws, and naturally only has an industrial machine tool.

"The industrial machine does not come out of thin air, it is also made by human semi-manual means. The delicate master, who was working on a long strip of ferrous metal object, smiled confidently: "I have slightly modified the machining table in the center of the five axes, added a feed carriage to fix the screws, the wire cutting tool, and ground the right diameter by hand. ”

"In the process of wire cutting, gas cooling is used. ”

Nodding, Ye Qing held up the five screws in a sealed plastic bag to the lamp for a closer look.

Different from the seemingly ordinary nuts, the screws inside the bag can be seen at a glance.

Because it has no threads, the whole body is smooth, and the surface looks bright, but there is no reflection. Vacuum evaporation technology is used to coat the surface of the screw with a metal plating layer that improves the hardness.

With the screws in his pocket, Ye Qing drove to Zhongyun University.

On the way, Ye Qing called Professor Cai Chenning and said that the screws had been made and would arrive on campus in about fifteen minutes.

"Mr. Ye, if you make a call, I'll go over and pick it up, and I'm bothering you to send it in person. Professor Cai Chenning was a little excited, and didn't know what to do, and said that he would inform the Japanese University of Science and Technology of the news, so that these arrogant guys could have a good look.

After hanging up the phone, Professor Cai Chenning put down his laboratory work in high spirits. The Japanese University of Science and Technology is in the activity room of the robot club, and the members of the club on the side of Zhongyun are conducting technical exchanges on robot balance.

As we all know, in terms of robotics, the Japanese side is not strong in one or two points. In the field of industrial robots, they are the strongest with Anqi Heavy Industry. Many of the robot videos circulating on the Internet are either made by Anqi Heavy Industries, or there is a shadow of Anqi Heavy Industries.

For example, the robot that competed with a kendo master and beat the world's No. 1 kendo master was made by Anqi Heavy Industries.

At the same time, this Anqi Heavy Industry is also one of the parent companies of Amano Heavy Industries in China.

With the technical support of the parent company, Amano Heavy Industries has slaughtered all sides in the domestic market, and in just one year since its establishment, many domestic industrial robot companies have been squeezed.

In view of their overall strong robot technology, Zhongyun University has directly learned well.

Not long after the exchange between the Polytechnic University that day, I couldn't help but propose to take the small robots they brought over and try them out with the robotics club.

The president of the robot club came directly: "Aha~ Professor Kobayashii, our robot is very unfortunate, yesterday in the test, I found that there were some problems with the driver, and it may take several days to fix it." ”

Regarding Zhongyun University's war-avoidance behavior, Kobayashii gritted his teeth and was a little helpless.

The other party is just a college student, and he can't say bluntly that you are a loser's quibble.

It's really sleepy to send a hot pillow!

Xiao Linjing, who was worried about not being able to find the other party, actually heard the news that Zhongyun University had made this screw.

Ha ha~

This nut has no solution in China!

This nut gift carefully prepared for Zhongyun University really cost Kobayashi a lot of brains and relationships.

Not only did he find JTEKT and entrust their industrial machine tool to help with the processing of threads. Together with two famous professors from the university's materials laboratory, the nut was coated with a nanodiamond film using the most advanced plasma vapor deposition method.

There are two aspects of the solution, one is that the ordinary five-axis machining center is simply not capable of the extremely demanding technology of cutting 300 threads with one knife.

Another insoluble solution is in the material, the thickness of 0.2 filaments, resting on the body of ordinary metal, will make the metal softer than paper. Even with special alloys, satisfactory hardness requirements cannot be achieved.

Only by using the plasma vapor deposition method to coat a layer of the hardest diamond film in nature can the thread of 0.2 wire reach the qualified hardness.

Looking at the world, only their countries can control the thickness of diamond plating at the nanometer level.

Precision and materials have always been Huaxia's weaknesses, and Kobayashi Jing also started from these two points to achieve the unsolvable problem on the nut.

Now that Zhongyun University says that the screws are done, of course Kobayashi will not believe that the other party can make qualified screws.

"That's great. Kobayashi Jing pretended to be very happy, shook hands with Professor Cai Chenning and said, "Zhongyun University and Nippon University of Science and Technology are separated from the country and the sea. We were founded in 1881 and your school was founded in 1953. ”

"Sixty-three years after the establishment of your school, our two schools have the opportunity to exchange and learn from each other. After this time, I don't know what year and month, we will have the next chance to communicate. ”

"I don't have hope, wait until that time. Kobayashi Jing switched to a sighing expression: "However, the friendship between our two schools. It is closely connected by a nut and a screw. ”

"Even after 200 years, the nuts and screws that attest to the friendship between our two schools can be preserved in their entirety for students to remember this history. ”

"Chen Ningjun, I implore you to put this unforgettable moment of friendship in the auditorium of your school, so that more students can remember this moment!"

Kobayashi is bent over ninety degrees, and his attitude is impeccable and sincere. (To be continued.) )
