"Boss He."

Glasses heard the movement, looked back, and said hello to the boss.

The boss asked, "What is Liu Gong doing, can it be repaired?" ”

Sweat oozing from the forehead of the glasses: "It's almost over, just adjust a few more parameters." ”

The boss obviously ran out of patience: "The day before yesterday, you said that it was fast, what parameters are you adjusting for three days?" ”

"There are some parameters that you have to try one by one. ”

The boss didn't get angry and waved his hand: "Then you can rest first and let this little brother take a look." ”

The glasses glanced at Lin He, a little unhappy, but he still silently let it aside.

It's good to let this kid suffer a little, so as not to make this Boss He feel very incompetent.

Lin Hedang didn't see it, and asked Boss He: "What is the specific situation of the machine?" ”

Boss He didn't understand, so he looked at his glasses.

The glasses said expressionlessly: "The machine ran out of battery, causing the program to be lost and the system was paralyzed. ”

Lin He nodded, knowing the reason, it would be easy to do!

The numerical control system will cause the paralysis of the numerical control system due to the long-term idle of the machine tool, the failure of the battery, the operator's operation error, etc., and the numerical control system must be reinstalled and adjusted in this case.

But now the system can start normally, apparently it has been reinstalled.

Fortunately, it's not a big problem if it's not a motherboard damage.

The rest is to adjust, simple to say, simple to say not simple and not simple.

As with the previous one, there was trouble with parameter adjustments.

Devils like to keep one hand, and the glasses are obviously stumped by those parameters that leave one hand.

Lin He asked, "You cleared all the parameters of the machine tool?" ”

The glasses denied: "I didn't clear it." ”

Lin He asked, "Who installed the system?" ”

The face of the glasses is unnatural: "I didn't pretend it." ”

The boss interjected: "Two people have come to fix it before." ”

Lin He nodded, didn't ask again, checked it, there was nothing wrong with the system, the secret-level functional parameters were set, and one-third of the manufacturer's data parameters were wrong.

It's a minor problem for him.

Fanuc's system is really familiar.

Lin He was not in a hurry to deal with it, and looked at Boss He: "The problem is not too big, how much money does the boss give?" ”

Zhu Ping breathed a sigh of relief first, it's good to be able to fix it!

The boss was suspicious, no matter how you look at this kid, he is a little unreliable, he is too young, he doesn't look like a master at all, but he can't look down on people before he sees that the mule is a horse, and says: "Three thousand yuan, but it must be completely repaired." ”

Lin He said yes and started working.

The glasses were a little unpleasant, he didn't believe that this young man had this level.

Cowhide who can't blow!

Fanuc's system parameters are not a big problem.,But the parameters given by the devil's manufacturer are more complicated.,He can't figure out the function of many parameters.,This little young cow B coaxed.,It's not good to fix it for a while, and you still have a cow B.。

Zhu Ping pulled the boss and chatted, since Lin He said that there was no problem, then there was no problem.

Although this nominal apprentice is young, he never brags about B.

After saying a few words, he saw the glasses standing aside and watching Lin He work, so he hurriedly pulled the glasses over and chatted a few words together. It is natural to teach skills to the workers in the factory, and it is not good to be stolen by outsiders.

Zhu Ping's life is transparent, how can he let people steal the teacher in vain.

Lin He didn't care about this, it took half an hour to adjust the parameters, check it, turn the selection switch on the machine panel to JOG mode, and then manually check the actions of each part.

The boss and glasses also came around, with different expressions.

After careful inspection, the mechanical transmission is normal, the motor overheating protection device is not active and the fuse is intact, and the motor fan and the ambient temperature are also normal, but the X-axis temperature rise is too high, and there is no alarm.

Zhu Ping checked the motor, there was no problem, and the indicator light of the servo unit was normal, so he suspected: "It may be a problem with the X-axis speed ring, the motor is overheated but does not alarm, it is not a problem of mechanical resistance and electrical failure, it is a problem of the system." ”

Lin He nodded, called up the real-time diagnostic screen, in the X-axis stop state, it was found that the flash amplitude of the No. 22 parameter was significantly greater than the others, so it can be judged that the fault is on the motherboard, and at the same time, it was found that when the machine tool stopped, that is, the zero speed command, the speed loop was still monitored and there was still a non-zero speed command signal output, which showed that the speed loop was in an unstable state of self-excited vibration.

It is this self-excited vibration that ultimately causes the high-frequency self-excited vibration of the current in the servo motor, which makes the temperature rise of the motor too high.

"It's a parameterization problem."

Lin He breathed a sigh of relief, as long as the cause of the failure could be found, it would be easy to do.

Called the parameter setting, found that the backlash compensation of the No. 6 parameter was set to 0.25mm, which was the parameter set by the glasses before, and he felt that there was no problem when he checked it, but now it caused the current in the X-axis servo motor to high-frequency self-excited vibration.

Considering that the actual mechanical backlash of the adjusted machine tool is very small, the No. 6 parameter value is set to be smaller.

Then re-checked, the fault is gone.

"Boss He, I still have something to do, so I'll leave first!"

The glasses were hot on his face, and he quickly flashed after saying hello to the boss.

Apparently there is no face to stay.

Boss He is a particular person and personally sends people out.

Although people can't fix the machine, they can't offend people in vain.

Mountains and rivers still meet, who knows if there will be a place to use people in the future.

Zhu Ping asked, "Are you okay?" ”

Lin He nodded: "There should be no problem." ”

"Try it then!"

Zhu Ping found a workpiece and prepared to test cutting it to see the situation.

Lin He entered the parts processing program and started the machine.

Boss He came back soon, smiling: "Little brother is amazing!" ”

Lin He said a few polite words and gave up the follow-up negotiations to Zhu Ping.

Boss He is very good at being a person, knowing that the two of them have not eaten, so he asked people to prepare meals, invited the two to the canteen to eat, and called a few workers to personally operate the machine tool to try cutting, and after making sure that there is no problem, it can be regarded as rest assured.

The meal was quite hearty, with four dishes and one soup, which was much better than the food in Shengda's canteen.

Zhu Ping sighed as soon as he ate: "These private bosses are really willing to pay, look at this food, it is much better than ours, I heard that the wages of these private factories are much higher than ours, and the technicians can get five or six hundred yuan a month." ”

Lin He said: "There are also lower ones than us, right?" ”

Zhu Ping nodded: "Of course, private bosses are the most realistic, only those who have the ability will give you a high salary, and those who don't have the ability to work will pay you a high salary, and if you really want to live a mess, you will be driven away long ago." ”

After saying a few words, Boss He came in.

The two greeted each other, and Boss He sat on the side.

After saying a few words, he asked Lin He again: "How much is the little brother's salary in January?" ”

Lin He said truthfully: "More than a hundred." ”

Boss He was upset for him: "You state-owned factories are just unfair, at your level, giving a thousand children and eight hundred is considered less, if you are interested in doing it with me, I will give you two thousand in January." ”

Zhu Ping's hand trembled, and he almost blurted out a sentence.

Two thousand ...... in January

Do it for a year and ten years.

Lin He's face did not change: "Thank you for the love of the boss, the big factory is good as the big factory, I still have a lot of deficiencies to learn from the master, I have no plans to change jobs for the time being, if Boss He needs my service, just look for me." ”

Boss He regretted: "That's okay!" ”

Lin He said with a smile: "If there is an opportunity to make money, I would be grateful if you can introduce me." ”

Boss He was very happy: "There is no problem with this!" ”

……

After drinking and drinking, the two took the money, and the two rode their bicycles back to the factory.

It was half past ten, and it was already dark.

Zhu Ping brought a handlamp, barely lit up the road ahead, and pedaled the car fast.

I feel much more energetic than when I came.

Lin He's thinking diverged: "Master, you said that we don't go to work to get a maintenance store, and it is not possible to specialize in this kind of maintenance of machine tools, let's install a phone and print some business cards everywhere, and we will definitely be able to take a lot of work." ”

Zhu Ping vetoed: "Then how to do it, the class still has to be on, and the repair of machine tools is not as simple as you think, domestic machines will be repaired a lot, and we can't make a few dollars, and we can't repair a lot of imported parts to replace them." ”

Lin He said: "We can make the accessories ourselves, can you make them?" ”

Zhu Ping said: "How can it be so easy, I can process the domestic ones, but the imported ones will not work, our materials will not work, and the accuracy will not meet the requirements, otherwise who will spend a high price to buy imported accessories." ”

Lin He had no choice but to put this idea on hold.

Those eliminated machine tools in the factory are still okay with ordinary parts.

The parts that can be machined with high precision requirements are not enough.

Materials are a big problem, and many fields are limited by materials if they can't break through.

There is a complete set of process technology in the data package, but the technology alone is useless, the basic industry is not improved, and no matter how much technology there is, it is in vain, just like someone gives him all the drawings of the lithography machine, he can't make that thing......

You don't need to be given, it's in the packet.

Back at the factory, it was almost twelve o'clock.

Lin He counted a stack of old man's tickets and handed them to Zhu Ping.

"It's too much, I'll just take two hundred."

Zhu Ping also likes money, but the old man is very principled and only took two hundred.

Lin He carried the rest of the money and returned to the dormitory at exactly twelve o'clock.

Guo Peng was already asleep, and after being woken up by the sound of the door opening, he asked in a daze, "Why did you come back?" ”

Lin He said: "It's more than ten kilometers, and it takes two hours to go back and forth. ”

Guo Peng closed his eyes and opened them, and after a while he was fully awake, he knew that he had gone out to do private work, so he got up, and after his eyes got used to the dim light, he hurriedly asked: "How much did you earn this time?" ”

Lin He didn't tell the truth: "A few hundred yuan!" ”

Guo Peng sighed: "You are a cow batch, and if you take a few private jobs a month, you will catch up with a year's salary." ”

Lin He yawned: "Please have dinner tomorrow, remember to call Yang Xiaohong." ”

Guo Peng nodded again and again, and the feeling of Zai Tuhao was also very refreshing.

Go to work the next day.

Walking to the door of the workshop, Su Xiaomei poked her head out: "You went to do private work again last night?" ”

Lin He was surprised: "How do you know?" ”

"What Guo Peng said!"

"I'm in for a treat in the evening!"

"Please?"

"Call your sister up!"

"Uh-huh!"

"Gone!"

Lin He waved his hand and went into the workshop to order something.
