The last class of the afternoon was a practical training class, and after class, Wang Chaoyang kept Jiang Hao as usual.

The squad leader, Li Dongmei, walked up to Jiang Hao quietly and asked in a low voice, "Why does Teacher Wang leave you alone every time?" ”

"Nothing." Jiang Hao said as he picked up a broom and pretended to sweep the floor.

Secretly using the machine is a secret between him and Lao Wang, so naturally he can't easily tell others.

Li Dongmei didn't believe it, she thought that Jiang Hao must have something good to stay.

A sour jealousy arose.

She felt very unfair in her heart, after all, she was the class leader, and if there was any opportunity to get close to the teacher, she should give priority to herself.

Li Dongmei simply took a broom and began to clean the classroom.

A few minutes passed, and seeing that she didn't look like she was leaving, Jiang Hao could only be anxious.

It's another bit of experience gone...

Wang Chaoyang, who had already cleaned up the podium twice, coughed lightly.

"Squad Leader Li, if you're okay, you can go back first."

Li Dongmei threw away the broom, ran to the podium quickly, and asked obediently, "Teacher Wang, do you need my help?" ”

"Thank you, the teacher is fine." Wang Chaoyang said.

"Then why does Jiang Hao want to stay?" She asked with a smile.

"Jiang Hao... He has recently been training in assault to prepare for a skills competition. ”

Wang Chaoyang didn't lie to her, and directly told the reason.

"Skills competition? Just him? ... That... Congratulations to Jiang Hao. ”

Why, why?!

Li Dongmei couldn't control the smirk on her face anymore, and left the classroom with her mouth shut.

Hum!

That Jiang Hao's usual grades are not very good, but Mr. Wang actually chose him to compete.

You should have chosen me!

Grievances turned into tears, like a summer downpour.

Wang Chaoyang waited for Li Dongmei to go away before taking out a stack of work drawings from the document bag.

"Boy, come and see."

Jiang Hao walked over and saw that it was the processing drawings of more than 50 main parts of the robotic arm.

He carefully read all the drawings and found that in addition to the rotating parts, cylindrical shells and bases that need to be processed and manufactured by lathes, there are also many complex special-shaped structural components that need to be processed by multiple machine tools.

It's not easy.

"Hey, boy, now you know that cowhide isn't blowing." Wang Chaoyang said with a smile.

Jiang Hao nodded while thinking about the processing method.

Wang Chaoyang looked at Jiang Hao frowning, and there was a hint of joy in his heart.

This time, this kid should be humble enough to ask me for advice and learning.

"Ahem!"

Wang Chaoyang interrupted Jiang Hao's thinking with a cough, and said proudly: "CNC machine tools are the teacher's best, you have to study hard." ”

In modern society, if we talk about multi-machine tool processing, it must be inseparable from CNC machine tools.

CNC machine tool is an automatic machine tool equipped with a program control system, which can make the machine tool move and process parts according to the programmed program.

Generally speaking, it is a CNC machine tool that integrates the functions of lathes, milling machines, planers, etc., and can automatically process workpieces.

Compared with lathes, the workpiece and cutter head in the CNC machine tool can be rotated, and there is no need to stop and change the tool during the processing, adjust the direction of the workpiece, and realize the automatic production of the workpiece.

It is decades ahead of manual lathes.

Many people in the society think that if they learn CNC machine tools, they don't need to learn ordinary lathes.

This is wrong.

There are at least tens of millions of CNC machine tools that can achieve ultra-fine machining below millimeters, and they may not be available because of technical control and other reasons.

But a master craftsman with real technical strength can make it with ordinary machine tools.

In the manufacture of certain high-precision workpiece parts, the craftsmanship is often more reliable than the machine.

In 2013, ordinary CNC machine tools had to buy about 1 million yuan.

They only have two CNC machine tools in Yangcheng Electronic Machinery Vocational and Technical College, and they are second-hand goods eliminated by the processing enterprises they bought.

Jiang Hao saw that Wang Chaoyang was about to start the machine, and hurriedly said: "Mr. Wang, I want to use manual machine tools to process these parts." ”

"What?!" Wang Chaoyang thought he had heard it wrong.

"How can this work! If so many parts are all machined by manual machines, how long will it take?

If you think CNC machine tools are not easy to learn, I can teach you a few more times. ”

Wang Chaoyang was not worried that the school would find out about the long processing time, but felt that it was too bitter for Jiang Hao.

You must know that as long as the CNC machine tool is programmed, it is only used to watch it on the side. Manual machine tools require a person to operate the machine all the time, and the slightest distraction can be wasted.

It's too tiring to have to machine so many parts in a week.

Jiang Hao said seriously: "Lao Wang, I want to use manual machine tools to accumulate experience first, and then learn CNC machine tools when I have rich experience." ”

Wang Chaoyang looked at him, didn't speak, only nodded.

Jiang Hao has already used the lathe very skillfully, and Wang Chaoyang has also demonstrated it to them in the previous training class of planers and grinders, and he believes that Jiang Hao should be able to operate.

As for whether the technical level is good or not, we can only wait for him to process it before making an evaluation.

The main thing is that this kid has surprised him too much these days.

He didn't dare to think about it.

When Jiang Hao began to process the first part, Wang Chaoyang received a call from Wu Liang.

He took the key to the training workshop from his waist, handed it to Jiang Hao, and left after some advice.

Waiting for Wang Chaoyang to leave, Jiang Hao called up the system panel.

He had also used planers and grinders in his previous life, but much less often than lathes.

[Host: Jiang Hao]

[Skill Card 2: Fitter]

[XP: 13 points]

[Rating: Primary]

[Evaluation: miserable]

What Jiang Hao didn't expect was that the planer and the grinder shared a skill card, and they both belonged to the type of work of the fitter.

However, this assessment does hurt people's self-esteem a bit.

I can't help it, just practice slowly.

The system is heaven-given, and you have to earn experience points yourself.

In the face of these more than 50 parts, Jiang Hao's method is to first make it easy and then difficult.

Because he found that after the experience point increased, he could really improve his operation level. In this way, as long as his experience points are getting higher and higher, even if it is a difficult part, it will not take too long.

He didn't even go to dinner, and he went from six o'clock to eight o'clock.

After he finished working on seven parts, the phone rang.

"Hey, are you Jiang Hao?"

The phone number is Wang Chaoyang's, but the voice on the other end is very unfamiliar.

"It's me, who are you?"

"I'm the doorman at the main gate, come and pick up your teacher at the door, he's drunk."

"Okay, I'll be right here!"

Jiang Hao immediately turned off the machine, locked the door, and ran to the school gate.

When he arrived at the guard's room, he saw Wang Chaoyang throwing up with a garbage can.

"Lao Wang, what's wrong with you?" Jiang Hao asked.

Wang Chaoyang: ... yue...

"Hurry up and help your teacher back." The doorman said.

Wang Chaoyang waved his hand: "No, I'll be fine right away... yue!”

The stubborn Wang Chaoyang woke up after Yue half a trash can.

"Lao Wang, why do you drink so much?"

Jiang Hao carried Wang Chaoyang and walked towards the classroom and dormitory.

"Not much... It's only a bottle and a half... After drinking so much, Wu Liang still doesn't let go..."

"You went to drink with him just because he promised me to form a team?"

Jiang Hao's eyes were moist, and even his voice was a little unnatural.

Wang Chaoyang really paid a lot for him to compete.

"It's not just for you, the teacher really wants to prove to the whole school that the students in our machining class are not bad... What courses on artificial intelligence and cloud computing are opening now, they are all cheating money and students! ”

"The foundation of industrial take-off is still the screws, the bearings... Boy, keep your feet on the ground! ”

Wang Chaoyang muttered, slurred and incoherent. But Jiang Hao kept every word in his heart.
