"It's still early, why don't we test it?" Wu Zhensheng asked.

"Okay, let's try the machine first to see if it can meet the design requirements." Chen Yu nodded.

Wu Zhensheng took out his mobile phone and made a call.

After a while, Li Dazhu and two people from the maintenance department came in with some things.

After pulling a wire and plugging it in, Chen Yu said, "Bring a few buckets of water." ”

When the machine tool processes parts, coolant is needed to cool the tool, otherwise, the tool will burn out in a few clicks.

Coolant is generally divided into cooling oil and cooling water, the temperature generated by the tool in the process of cutting metal will make the cooling oil deteriorate, which will cause some people to have skin allergies, injections and rubbing drugs will affect health.

When designing the machine tool, Chen Yu considered the problem of coolant, so when he made the CNC lathe, the metal parts except the tool were made of alloys that were not easy to rust.

After programming the program, loading the processed parts, and adjusting the position of the tool, Chen Yu pressed the start button.

When the motor runs up, the round steel fixed by the fixture rotates rapidly, the cutter slowly descends, the water pours down, the thin iron cut splashes, and in an instant, the front end of the round steel is cut off.

The cutter is reset, the second knife is lowered, and in the blink of an eye, the top of the round steel becomes a cone.

The No. 2 knife returned to its position, the No. 3 knife descended, and in the blink of an eye, there was an extra groove on the round bar......

Picking up the processed parts, Chen Yu measured it with a micrometer and measured the angle with a projector.

"How?" Wu Zhensheng asked curiously.

"The size meets the requirements, the accuracy is 0.005 mm, that is, 0.5 wires, and the accuracy I designed is 0.1 wires, but unfortunately the performance of electronic components and the speed of the motor are not up to the requirements." Chen Yu said with a smile.

"Such a high level of precision?" Wu Zhensheng asked in disbelief.

"If you don't believe me, you can test it yourself." Chen Yu said.

Wu Zhensheng took the parts, inspected them himself, and then asked, "Xiao Chen, can you sell me a machine tool?" ”

"Director, you also know that the price of CNC machine tools with such precision is not cheap." Chen Yu said with a smile.

"Half a million units, how about one?" Wu Zhensheng gritted his teeth and asked.

"Okay." Chen Yu nodded, the cost of materials is more than 10,000, one sells for 500,000, he has already made a lot, although he can sell more than 1 million when he goes outside, but he can't really charge the other party 1 million, right?

Gambling stones made hundreds of millions, hundreds of thousands of banknotes, and he couldn't look down on it anymore.

"Let's try the mill again." Wu Zhensheng said with a smile.

Ten minutes later, Chen Yu said: "The milling machine has an accuracy of 0.5 wires, and the performance is not bad. ”

"200,000 units, sell one to me." Wu Zhensheng said.

"No problem." Chen Yu nodded in response.

"Try the grinder." Wu Zhensheng couldn't wait to say.

After another ten minutes, Chen Yu said: "The accuracy of the grinding machine is 0.3 wires, which is okay." ”

"This two-axis grinding machine, 200,000 units, sell one to me." Wu Zhensheng said.

"Okay." Chen Yu responded with a smile.

"Director Li, call someone over and move these three used machines to the new workshop." Wu Zhensheng said.

"Yes." Li Dazhu nodded in response.

"In the future, there is no need to buy imported machine tools, no, there is Xiao Chen, and there is no need to buy any machines in the future." Wu Zhensheng said with a smile on his face.

The test machine just now can startle everyone, the accuracy of the three machines, than the machine tools, milling machines, and grinding machines imported from abroad by Sanyang Machinery Factory, are much stronger.

"Director, with these machines, we can process drill bits." Chen Yu said.

"Hmm!" Wu Zhensheng nodded, and said, "Xiao Chen, you have to teach Director Li how to program." ”

"Programming is very simple, I use Chinese pinyin and numbers for programming, such as No. 1 Knife Zero, dao1gui0......" Chen Yu introduced with a smile.

"Didn't use English?" Li Dazhu asked suspiciously.

"What are you doing in English? It's troublesome to learn, it's troublesome to use, forget it, I'll get a copy of the information, and you can follow the programming when the time comes, and it won't take a few days to learn. Chen Yu said.

"As far as I know, the PLC only supports English and numbers!" Li Dazhu asked suspiciously.

"Change the program in it, won't you be able to recognize pinyin?" Chen Yu said disappreciatively.

"Xiao Chen, will you still change the procedure?" Wu Zhensheng asked dumbfounded.

"Didn't I make the software used by Fujiyama Investment Company?" Chen Yu asked rhetorically.

"yes, how did I forget about it." Wu Zhensheng patted his head.

After more than two hours, the remaining nine CNC machine tools, two CNC two-axis grinders, two CNC five-axis grinders, and four CNC milling machines were successively moved to the idle workshop of the Fujiyama Smelter.

"When the tungsten carbide wire rod is made and the grinding wheel is bought, the drill bit can be produced." Wu Zhensheng said with a smile.

"It's not too early, if there's nothing else, I'll go back first." Chen Yu said.

"Be careful on the road." Wu Zhensheng said.

Chen Yu nodded and rode away.

The next morning, he came to the school again, it will take a few days to officially produce the drill bit, he has nothing to do, he had to go to the school to study, looking at the beautiful Tang Shi, he couldn't help but be moved.

"The top beauty who has not yet grown up has a special charm, and it is so moving now, and it will definitely be more beautiful in the future!"

Before he crossed over, Chen Yu always regretted that he didn't play a girlfriend when he was studying, which made him in his thirties and still a single, but now he has crossed over and returned to his student days, how can he miss the opportunity?

"From the beginning to the end, unswerving love, who can not care?"

Smelling the faint fragrance and looking at the teacher on the stage, Chen Yu, who looked sluggish, quarreled in his mind.

"She is mine, she is, she will be, and she will always be!"

"She's only fourteen years old, a little girl, what's so good?"

"You cow, you're in your thirties, why are you still a bachelor?"

"I've at least had a deep communication with women, and you're a little kid who doesn't understand anything!"

"I am you, and when you scold me, you are scolding yourself."

"Yes, you are me, I am still me, anyway, I think a plump woman is more attractive."

"Do you dare to say that you don't like beautiful girls?"

One thought after another flashed in his mind, and after asking himself, he found that he had fallen in love with Tang poetry.

"Chen Yu, come up and do this question." Sun Zhengfeng shouted.

When he came back to his senses, he walked up briskly and finished the question on the blackboard in a few clicks.

"You can do such a difficult question?" Tang Shimei asked with flickering eyes.

"Don't look at who I am?" Chen Yu said in a low voice.

"Hmph, what's there to be proud of?" Tang Shi pretended to be disdainful and said.

"How about I'll take you to and from school in the future?" Chen Yu asked in a low voice.

Tang Shi was overjoyed in his heart, and did not nod or shake his head, but asked, "Why?" ”

"A girl in the third year of junior high school is not ...... Anyway, I'm on the way. Chen Yu said.

During recess, he heard from his classmates that there was a girl in the third year of junior high school......

"Hmm!" Tang Shi's voice was like a mosquito and a fly.

"What time does school end at night? What time do you start studying in the morning? Chen Yu asked.

"I go to self-study at 7 o'clock in the morning and leave school at 10 o'clock in the evening." Tang Shi said.

"Okay, every morning at half past six, I will wait for you at the noodle shop, and at ten o'clock in the evening, I will come to the school to pick you up." Chen Yu said.

"Wouldn't it be too much trouble?" Tang Shi hesitated.

"What's the trouble?" Chen Yu said with a smile.
