After eating, the two walked to the dormitory bathed in the warm spring sun.

The school campus is small, but the main road is covered with ginkgo trees, and the green leaves rustle in the breeze.

Ma Dong picked his teeth, still savoring Zhang Lingling's taste.

"Hey, I can't imagine that falling out of love is like this." He grumbled.

Jiang Hao: ...

"Adong, concentrate on studying, now is not the time to fall in love." Jiang Hao could only be so consoled.

Ma Dong's eyes widened, and he said, "When will you talk about it if you don't fall in love now?" Twenty years old is the age when hormones have nowhere to vent. ”

"Adong, if you don't study hard, you can only go home to raise pigs in the future." Jiang Hao couldn't help but remind.

"Eh, how do you know that my dad is planning to open a pig farm." Ma Dong's expression was even a little excited.

"In the future, I will inherit my father's pig farm and hundreds of acres of land, and she Zhang Lingling will not be able to catch it."

He made a gesture of a leopard's head clenching his fist.

"Then wait for the future, at least now you can't compare with Li Siyuan. Someone else is the president of the student council, you are the president of the 404 dormitory DOTA association...

Others are tall and handsome, you are short and... Implicitly..."

Ma Dong: "Brother Hao, you can say a few words." ”

Jiang Hao: "Okay. ”

In order to prevent his good brother from becoming a licking dog, Jiang Hao also tried his best.

Back in the dormitory, the gloom on Ma Dong's face was swept away, and he began to organize a team in the dormitory next door to play DOTA.

Give full play to the glorious mission of the President of the Dota Association.

Jiang Hao lay on the bed and flipped out "CNC Machine Tools from Mastery to Entry".

There was a two-hour break at noon, and he was ready to sleep a little more when he was tired.

"Damn, Brother Hao, aren't you coming?" Ma Dong was surprised.

Jiang Hao waved his hand and said, "I'm not coming, I'll read a book for a while and prepare to take a nap." ”

The other two roommates in the dormitory who were in the e-commerce class also turned their heads over.

"Brother Hao, you seem to be a different person today."

Jiang Hao sat up from the bed with a carp and shook his fist solemnly.

"From today onwards, I am ready to study hard and work hard."

"Cut!" ×3

The three of them dispersed, and soon devoted themselves to brainstorming the game's selection strategy.

Jiang Hao sighed.

In the past few years of junior high school and high school, which are proud of their scores, technical school students have long been worn out of their hearts, and most of them have become self-defeating.

Seeing no hope for the future, he chooses to numb himself with short-term pleasures.

Jiang Hao in his previous life was not like this.

It's just that he lives again, and he knows that the pleasure of indulgence now will have to be repaid with hardship later.

He had to work harder to be worthy of the hardships he had endured.

...

More than half an hour later, Jiang Hao was about to fall asleep in a daze when his mobile phone rang.

"Jiang Hao, now come to the training workshop." Wang Chaoyang on the other end of the phone said quietly and mysteriously.

Jiang Hao thought for a moment, then smiled.

Mr. Wang, this is going to open the back door for me...

When he arrived at the training workshop, Wang Chaoyang pulled him into the workshop and closed the door from the inside.

Wang Chaoyang: "From now on, during the lunch break, between 1 o'clock and 2 o'clock, you will come to the workshop to use the machine, whatever you want!" ”

Jiang Hao: "The lathe is so noisy, in case someone finds out, I secretly use the machine..."

Wang Chaoyang: "Don't be afraid, during the lunch break, everyone is sleeping." ”

Jiang Hao: "Hmm. You have a point. ”

"Then you can practice on your own, I'll go out for a cigarette and take a walk by the way." Wang Chaoyang said and left.

Jiang Hao knew that he was taking a walk, but he was actually going to help him let the wind out.

"I'm really lucky to meet a teacher like Lao Wang."

Jiang Hao sighed with emotion as he started the lathe.

Since it's an exercise, there are no set requirements. He has only one goal, which is to make the technical difficulty as possible.

The main thing is to get experience points for the system as soon as possible.

After fixing the material to the chuck, Jiang Hao decided to machine a thin-walled sleeve.

Lathe is a kind of industrial machine tool and is the most important cutting machine tool in metal cutting machine tools. Its function is to cut rotating surfaces of various sizes and shapes, as well as spiral surfaces.

The working logic of the lathe is to fix the material to be processed on the chuck, rotate by the spindle at high speed, and then the worker operates the tool to get close to the rotating material to achieve cutting.

Lathes are mainly used to process shafts, discs, sleeves and other workpieces with rotating surfaces, and are the most widely used type of machine tools in machine manufacturing and repair factories.

Regardless of the types it processes, it is not complicated, but these types are the most used and most common components in mechanical engineering.

Therefore, the lathe is also known as the 'working machine'.

It is the basic technology of machining, but often the foundation determines the height of the upper layer.

Jiang Hao concentrated on hollowing out an inner cavity of the cylindrical material, and then continuously reduced the thickness of the wall.

As the wall thickness is reduced to 1 cm, the technical difficulty is increasing. Because the speed of the workpiece is 300 rpm, a slight shake in the hand may cause the tool to hit the wall and cause the workpiece to crack.

This time he's not the 5-minute man who pursues speed.

After more than half an hour of processing, beads of sweat had already formed on his forehead before he pressed the switch of the lathe.

He measured it with a vernier caliper, and the wall thickness of the workpiece reached about 8mm.

After all, it is the first time to challenge this difficulty, and it is normal for the wall thickness of the workpiece to be incorrect.

Jiang Hao felt that after he was reborn, once he touched the machine tool, his mood became very calm, and he was able to devote himself to the use of the machine.

This feeling of unity of body and mind was something he had never felt before.

I don't know if it's because of the system or if I really like machining.

He hurriedly called up the system panel to see how his experience points had increased.

[Host: Jiang Hao]

【Skill Card 1: Turner】

[EXP Points: 27 (+3)]

【Rating:Intermediate】

[Evaluation: Small achievements come from your intentions]

That's 3 XP?!

It seems that it is not about machining a workpiece to get 1 experience point, but the more you put in it, the more you increase!

Jiang Hao felt that he understood the true intention of the system.

It is to train itself to become a master craftsman.

Jiang Hao looked at the time, there were still twenty minutes before the two o'clock class.

I feel like I can do it again!

He was about to load the second material when Wang Chaoyang walked over.

"How's your practice?" He asked.

Jiang Haofeng lightly handed the thin-walled sleeve that had just been processed to Wang Chaoyang.

"It's okay, it's only 8mm."

8mm？

You say it's okay?!

Wang Chaoyang even felt that he hadn't touched the machine tool for many years, and he was a little unworthy of being a teacher at the practical level.

"Well, it's okay." Wang Chaoyang also said lightly.

He looked into the machine tool, then touched the tool, and finally found a place where he could point to Jiang Hao.

"Boy, the teacher taught you, if you still want to challenge thinner walls, I suggest you specialize in the use of different knives. The lathe master is the perfect use of the cutter. Wang Chaoyang put his hands behind his back and said lightly.

Jiang Hao patted his head and said, "How did I forget this!" ”
