Chapter 22 The problem of not having a water jet cutting machine
A week later...

After the martial law was relaxed, in order to avoid restricting people from going out for too long, Polytechnic University began to adopt a real-name registration method to manage people entering and leaving.Regardless of foreigners or outsiders, if they want to enter the campus, they must write their name and ID number.

This measure manages the entry and exit of personnel, preventing some unknown personnel from entering and exiting at will when the school door is opened before, which greatly limits the actions of others who want to enter the campus except for employees, teachers and college students of the school.

outside the school gate.

After registering the access certificate, Li Youchen left the Polytechnic University alone, went to the smelting plant, and met with the person in charge, Director Liu.

Smelter, forged, piled in front of a pile of titanium alloy steel.

"What do you think? Young man, our smelter forged titanium alloy steel according to your method. The main component is titanium, which is 50.00% six, and the total of the other elements is about 44."

"Especially if you don't know the quality? I have to ask you, young man, to see it with your own eyes."

Director Liu pointed, wondering how to determine whether the forged titanium alloy steel was qualified?

This young man had to come first.

In the left eye, the virtual panel scanned, prompting: passed.

"no problem."

"How much? I want all the two hundred kilograms of titanium alloy steel." Li Youchen asked. He couldn't take it away for free, and planned to use the funds given by Teacher Zhao to buy it.

"No money is needed, I will give it to you for free. You provided me with the titanium alloy smelting technology, so why should I ask for your money? Two hundred kilograms of titanium alloy steel is worth making friends with you."

Director Liu valued talented young people very much. In order to thank him for giving him the smelting technology, he gave him a free gift so that he could make friends with him.

"Thank you. I don't know how to call you uncle?"

After shaking hands with him and thanking him, Li Youchen turned to ask.

"My surname is Liu, just call me Uncle Liu or Brother Liu."

Director Liu smiled and reached out to pat his shoulder.

"Then just call Brother Liu. If I need any materials next time, I'll entrust you with the forging. I'll ask Brother Liu to sell them to me cheaply."

"Of course, I'll give you [-]% off the market price. Whatever steel materials you want, we'll sell them to you at [-]% off."

"Thank you."

He was very polite, shook hands again, and Li Youchen thanked Brother Liu.

……

Baihong Manor.

After the titanium alloy steel was shipped, Li Youchen did not start manufacturing it immediately.

Instead, I made a call to Teacher Zhao Hong because there was a lack of processing equipment for titanium alloy steel.

That is...

"Machine tool equipment for processing titanium alloy steel?"

Zhao Hong hesitated for a moment and then said: "Is it the kind of processing equipment used to make parts?"

Li Youchen responded: "That's right."

"Teacher, regarding the processing equipment, a water jet cutting machine is needed for processing."

“Don’t know where to buy a waterjet cutting machine?”

"I want to ask the teacher, where can I buy it?"

Zhao Hong: "Waterjet cutting machines are very special. Currently, there is no such equipment in China that can easily process titanium alloy steel."

Li Youchen hesitated:
"There is no waterjet cutting machine for processing in China. Is it another overseas technology blockade?"

Zhao Hong: "Yes, it's this again. Even some equipment and technologies that are too small to be used must be blocked, and we are forced to choke our necks in terms of technology."

Li Youchen's face turned dark and he wanted to scold his mother!
Straight bitch!It wants to manufacture turbofan engines, but it also faces labor constraints in terms of processing equipment.Overseas countries are so fond of technological blockades that labor and capital must build waterjet cutting machines, turning your technological blockade into nothing more than a display.

"Teacher, hang up now. I'm looking for other ways. Can I replace the waterjet cutting machine?" Li Youchen hung up the phone and stopped talking for the time being.

Pictures, the only way to obtain the technical drawings for manufacturing a waterjet cutting machine is to collect and analyze the pictures of the waterjet cutting machine.

But where can I get the photos?

By the way, the library has all the detailed equipment explanations related to industry. With just a picture, you can get the technical analysis of the waterjet cutting machine.

At noon, after eating in the school cafeteria, Li Youchen went to the library.

I walked up to the second floor, went to the industrial knowledge area, and started looking for drawings about water jet cutting machines. I spent several hours searching non-stop.

As a result, it was not found.

Putting the book back to its original position, Li Youchen scratched his head and thought while stroking his chin with his right hand:

"do not have it?"

No, this time it was completely difficult!

In the industrial knowledge area, you can see any pictures of equipment related to steel processing.

There is just no waterjet cutting machine, high-definition pictures of this type of equipment.

Depend on!
How could there not be a library?There are so many introductions and pictures about processing equipment, but there is no water jet cutting machine that I want!
no!If you look elsewhere, you should be able to find pictures of waterjet cutting machine equipment.

He was about to go somewhere else, but something suddenly attracted his attention?

Stunned, Li Youchen looked to the left.

There is a lot of space in the corridor over there. It is still spacious and does not have any furnishings. What is there is just a blackboard that is only attached to the wall.

Li Youchen walked over there curiously, and happened to see a photo stuck between the blackboards with a magnet. He stepped forward to see what picture it was.
Unexpectedly, it was exactly this: high-definition pictures of waterjet cutting machines.

There are a few sentences above to introduce the water jet cutting machine:
Made in 1989, produced by Eagle Sauce Company.

Taking down the picture, Li Youchen scanned it carefully and admitted:

[Waterjet cutting machine construction technology analysis is in progress... (There is still a lack of knowledge source points, so analysis cannot be performed. Analysis requires [-] source points)]

[Existing knowledge source points: 0. 】

Entry completed.

Li Youchen thought he would not be able to find it, but fortunately he found a picture of a water jet cutting machine here.

Looking around, he didn't quite understand.

Who will be on the blackboard?Photos of waterjet cutting machines are here.

I couldn't find it before, but I found it here.

Without thinking too much, the core technology of water jet cutting machine is being analyzed by panel technology.

It’s better to go back quickly and prepare to collect knowledge sources.

Paste the photo back on the blackboard and secure it firmly with a small magnet.

After Li Youchen left, he walked down the stairs.

A few minutes later, someone came over with a few books. It was Mei Gan, a junior student.

The impromptu exam is coming, and Mei Gan is still preparing to review the knowledge related to the exam.

Go to the blackboard, pick up the chalk, and write down some knowledge points.

I found that the picture of the water jet cutting machine has been moved. It should have been placed next to it before. I don’t know how to move it from the side of the blackboard to the middle position?
"Strange, is the location here?"

Mei Gan moved the photo to the blackboard. Instead of delving too deeply into it, she picked up the chalk and wrote down a few knowledge points on the blackboard.

In order to prepare for the upcoming temporary exam, Mei Gan decided to review carefully.

Regarding the subsequent employment paths, the temporary examination will specifically check personal abilities. Which direction will be suitable for full-time employment?
