"Go."

Lin He came back soon and patted Guo Peng: "I said okay, go and invite people to dance." ”

Guo Peng was a little timid: "Okay?" ”

"Nonsense!"

Lin He wanted to go on his own: "If you don't go, if you don't go, I'll jump with others." ”

"I'll go!"

Guo Peng is a spirit, what kind of line is this!

I can't bear to dance with another man with the girl I like!

This is more useful than anything else.

Guo Peng walked over hard, and when he was still three or four meters away, Yang Xiaohong also found him.

Turning his head to look at it, he greeted with a smile: "Hello college student!" ”

Guo Peng's heart beat faster, and he stiffened: "That, can I ask you to dance?" ”

Yang Xiaohong smiled and nodded: "Okay!" ”

Guo Peng breathed a sigh of relief, feeling that his heart was about to jump out of his chest.

In fact, Lin He didn't say anything, just said that Guo Peng wanted to invite her to dance.

Yang Xiaohong is a cheerful girl, although she didn't agree directly, she didn't refuse.

If you don't directly refuse, you are acquiescing, at least it shows that people don't dislike Guo Peng.

As long as Guo Peng can take the first step himself, there is still a chance.

Watching the two walk towards the stage, Lin He smiled.

May all lovers in the world become dependents......

No, I should wish that good girls have a good home, and good men have a good daughter-in-law.

After sweeping around, no girl asked him to dance, so he quietly retreated.

When I went back to my dorm room, I took a book to read.

When it was almost nine o'clock, Guo Peng came back.

The peach blossoms on the face are blooming.

Lin He put down the book and asked, "How did you dance?" ”

"It's good."

Guo Peng was full of spring breeze: "I jumped five times." ”

Lin He's gossip heart surged: "What did you talk about?" ”

Guo Peng twisted: "I didn't talk about anything, just danced." ”

Lin He's eyes widened: "You hugged other people's waists and shook and shook, and you didn't talk anything?" ”

Guo Peng made a bitter face: "I don't know what to talk about!" ”

Lin He was anxious for him: "How can you not know what to talk about, you can even ask Sanwei!" ”

Guo Peng's eyes widened: "Damn, didn't you teach me to play hooligan?" ”

Lin He even compared: "I'll make an analogy, the purpose of dancing is to create communication opportunities, not to dance stupidly, girls like men to take the initiative, you just hug people's waists and shake and shake, but you don't even let go of a fart, I dare to promise to dance again at most, if you just care about dancing, there will be no third time." ”

Guo Peng was suddenly nervous: "Do you really want to speak?" ”

"Nonsense!"

Lin He hated iron and said: "Unless you want to see Yang Xiaohong dancing with other men." ”

"How's that going to work!"

Guo Peng suddenly became anxious: "What did I say?" ”

Lin He was so tired that he had to teach this fool patiently.

In fact, there is a sense of accomplishment, how can there be such an honest person who allows him to experience the feeling of being a life coach after a few decades.

The face-to-face machine should be taught for an hour, and the lights should be turned off at almost 10 o'clock to go to bed.

Lin He turned off the light and reminded: "With Yang Xiaohong, don't call Zhou Huimin when you dream at night." ”

Guo Peng almost died, and he didn't say anything for a long time.

When he was about to fall asleep, he said, "Don't tell Yang Xiaohong." ”

Lin He almost didn't laugh out of the pig cry!

When she went to work the next day, when she arrived at the door of the workshop, Su Xiaomei was already sitting in a small house.

Wearing a thief's ugly overalls, it's dirty.

Only the apple face is as beautiful as ever.

"Morning!"

"Morning!"

Say hello and enter the workshop, and go to the duty room to order first.

Then I went to the tool room to get the tools and cleaned up.

A newcomer is a newcomer, and the attitude must be correct, and college students are no exception.

In the past two years, there have been more and more college students, and they are no longer as popular as in the past.

In the 80s, when college students entered the factory, they were all put in the office of the institution.

No matter how bad it is, it is also put in the second-level organs for training and key training.

How can it not be thrown to the front line for maintenance.

Lin He didn't catch up with the good time, and he was assigned to the front line of the workshop when he entered the factory.

Wang Hongjun, the maintenance squad leader, was very satisfied with him, he was stupid when he first came, and he has made rapid progress in the past month, and he has matured rapidly in life and work, even better than some old comrades, which leader does not like such a good seedling.

After cleaning up, a routine morning meeting is held.

After repeating the same old tune, the focus fell on lathe repair again.

After discussing for a long time, I didn't discuss the ugliness of the child.

So the field research continued.

Lin He has just turned regular and is still in the learning stage, Wang Hongjun arranged a master for him, and asked Zhu Ping, an old technician with more than 20 years of experience in equipment maintenance, to take him.

Even though he could fix it, he didn't have a chance to show it.

The machine is Yamazaki Mazak's bed, the original import more than ten years ago.

It is also the only CNC lathe in the factory, and it is still a second-hand product.

Now the problem is that in the process of machining, there is MCS DIFF OVER T, that is, the rotary cutterhead overload alarm, which appears once a month at the beginning, and can continue to work after resetting, and the operator does not care, but now there are more and more frequencies, and the situation is getting more and more serious, which has seriously affected the normal use of the machine.

The fault is simple, but the phenomenon is strange.

The maintenance personnel studied it for several days and did not know what the problem was.

Several maintenance workers did not give up, re-checked, the connection between the motor and the cutterhead was disconnected, the cutterhead rotation was executed, the motor rotated normally without abnormality, and the connection between the motor and the cutterhead was restored, and there would be a fault, which showed that the fault should occur when the cutterhead motor was loaded, and the electrical problems were temporarily ruled out.

Check the hydraulic system, the cutterhead clamping and loosening status is normal.

The pressure can reach the set pressure, and the hydraulic system is no problem.

According to the mechanical structure pattern, the cutterhead is slowly disassembled from the outside to the inside.

This guy is a bit old, the mechanical parts of the cutterhead have never been disassembled, several maintenance workers are careful to disassemble, Wang Hongjun is also worried, the devil's things are too precise, often disassembled and uninstalled, it's not news.

If something goes wrong, the responsibility is great.

Just dismantled the cutterhead, the factory director Zhang Zhenguo came over.

Come to the site in person to understand the progress of the repair.

It was followed by Chen Kaijun, deputy director of the equipment factory, and Li Guoping, director of the machining branch, and several deputy directors of the branch and the heads of the equipment department also followed.

The factory director came in person, and several maintenance workers were under great pressure and became more and more careful.

"Nervous eggs!"

Zhang Zhenguo had a loud voice, his style was still always rough, and when he saw a few maintenance workers nervous, he immediately shouted: "Tear down how you want, don't care about Lao Tzu, it's all iron lumps, I'm afraid of a bird's egg, how can I learn to repair it if I don't dismantle it a few times." ”

The factory director who claims to be Lao Tzu is really rare.

But everyone is obviously used to it.

Several maintenance workers were more nervous and more cautious.

What the factory director said sounded good, but he couldn't afford to take this responsibility if he really broke it.

After disassembling the cutterhead, you can see the internal cutterhead clutch, oil cylinder, piston rod and transmission gear and other components, and there is no obvious wear, fracture and deformation, the oil cylinder has oil leakage, but it is not very serious.

Obviously, the problem is not here.

I reassembled the cutterhead, turned it on and tried it, and the rotation of the cutterhead was beautifully completed.

But soon, the fault reappeared, and the cutterhead was overloaded during rotation and alarmed.

Several masters were numb and couldn't figure out what was wrong.

"What the hell is the problem?"

Zhang Zhenguo asked with a glare, obviously very irritable.

The order over there is tight, and the delivery date cannot be delayed.

The lathe that can process the shaft gear has a problem, and it is strange that the mood should be good.

Ordinary lathes are not unable to process, the precision of the rotating shaft gear is high, the ordinary lathe processing has high requirements for the technical level of the operator, and the slight operation is not good will become a waste product, and the pass rate cannot go up.

Otherwise, I wouldn't have spent a lot of money to drag people and relationships to buy this fully automatic thing.

Several masters couldn't answer, and Wang Hongjun quietly wiped his cold sweat.

The factory director is majestic, and if he is in a bad mood, the people below him are under great pressure.

Several workshop leaders also had their legs and stomachs spinning, this baby bump could not be repaired well, and they could not escape responsibility.

Only Lin He didn't feel the pressure, and looked at Director Zhang quietly.

Although Director Zhang is a big old man with a big face that has been weathered, but if you look closely, you are actually quite handsome, with three-dimensional facial features, no wonder the girl is so beautiful, which shows that people's genes are also very good.

That is, the wrong era was born.

If you are born decades later, Director Zhang can also eat with her face.

However, the current director Zhang was in a very bad mood, pacing around irritably, pacing and scolding: "A bunch of rice buckets, even a piece of equipment can't be repaired, what do you want, Li Guoping, what the hell are you eating?" ”

Li Guoping, the director of the branch, kept wiping cold sweat and didn't dare to say anything.

Director Zhang was puzzled and reprimanded all the leaders.

Chen Kaijun, deputy director of the factory, suggested in a timely manner: "Or find someone from the manufacturer to repair it, and the delivery cannot be delayed." ”

The heads of the equipment department and the branch agreed in their hearts, but they didn't dare to nod.

It is no secret that Deputy Director Chen has a hard background, openly and secretly competing with Director Zhang, there are people in the workshop to discuss, no one wants to be a sandwich biscuit, in case you accidentally become cannon fodder, it will be too late to cry.

Li Guoping wanted to refute, but he had no confidence.

Director Zhang was even more angry: "You can't even fix an iron lump, why do you raise so many repairmen in the factory, Chen Kaijun, what are you doing to eat, what do you go abroad to learn, you can't take it out at a critical moment, do you want to be the deputy director of the equipment to have a fart?" ”

Deputy Director Chen's face was a little green, but it was difficult to refute.

The number one is still the number one, and the authority is not so easy to question.

Lin He watched the excitement for a long time, and couldn't help it: "Could it be a problem with the drive controller?" ”

"Impossible!"

A maintenance worker retorted on the spot: "If it was a drive problem, the drive controller would have alarmed, and now it is an overload alarm for the motor, either an electrical system problem or a mechanical problem." ”

Everyone nodded their heads, this is the normal logic.

Lin He said: "This lathe has been used for almost 20 years, and electronic components are the most prone to aging, and the aging of the drive controller will lead to a decline in the performance of electronic components, and the performance of electronic components will decline, and it may also trigger an overload alarm for the motor." ”

"And that said?"

A few masters don't believe it, and it doesn't make sense logically.

Zhang Zhenguo shouted: "Just take it apart and see if you can find out." ”

A few masters didn't dare to talk nonsense anymore, and hurriedly dismantled the drive controller.
