After going home, I took out two buns from the secret realm, the old rules, baked hot and burned, ate the pickles, drank a large jar of warm water, and today I was thinking about the machine tool, I didn't care about drinking water, and I felt thirsty when I went home to eat.

Take out the file bag, because it is an ordinary document, there is no seal, otherwise it will not be so easy to get, let alone take it home, bypass the buckle, take out all the information, part of it is the maintenance record, the record is detailed: workshop number, repair person, maintenance time, what failure, who is the repairer, process, result, inspection signature, confirm signature.

I heard the master say that in the past, there were almost no records in the factory, the maintenance was very casual, and things such as losing screws and less sealing strips appeared frequently, and various tricks were used, and the effect was average. Later Sue. When the big brother supports the technology, it also brings these requirements, although the heart is resistant, but once the order is given, all of them are implemented. Slowly the benefits are reflected, things are more standardized, there are fewer sloppy operations during maintenance, and all parties have a basis for judging, and now leaders at all levels are willing to strictly implement it.

After briefly reading the maintenance records, I know that the various failures of this machine tool in recent years, most of them are to replace wear parts, but there is no way to guide rails, and it is recommended to purchase new guide rails for 30 years. Generations of old objects, where to buy.

I was about to look at the technician's hand-drawn structural drawings when I heard a knock on the door.

When I opened the door, it was Widow Qin.

"Guocheng, I've eaten" saw the information on the table, "Roar! What about learning", Widow Qin turned around and came to the house, passing by without knowing whether intentionally or unintentionally, slightly. Ball. Bumping people.

"Sister Qin, it's so late, what's the matter with you", Li Guocheng reminded Widow Qin, it's too late, you have to pay attention to the impact.

"I just finished serving the family, come to you to see if there is any sister who can help", after speaking, he naturally threw an eyebrow. Eye, there is one thing to say, although the Qin widow is in her 30s, she has a talent hook. Human, feminine. Flattering, inadvertently revealed, the average old man is really difficult to parry.

As the soul of the afterlife, it is a personal habit to love cleanliness, and it is very difficult to accept the sloppiness before the original owner.

"Thank you, Sister Qin, the family is poor and white, and there are not many things to clean up, so I will clean it up with my hands."

"Okay, Guocheng, your newly painted house is indeed bright, and our house will be cleaned up like your house in Ming'er", Widow Qin chuckled and turned into the bedroom.

"Your bedroom is too neat, I didn't expect you to be a big man who can clean up", Widow Qin complained and boasted.

Li Guocheng didn't dare to follow, now there is no bookcase, the whole house is very transparent, and it is not rude not to follow. Li Guocheng deliberately stood in the living room near the window, under the projection of the light behind him, it was very easy to see Li Guocheng's actions outside.

Widow Qin turned around, and every time it seemed to be a thousand tempers, it was natural. It's dizzying. But for Li Guocheng, these are all small tricks and disdain.

"You're not too young, and you don't have anyone to hurt, how about introducing you to someone? My cousin, who is the same age as you, must have a good look, a good figure, inherit our old Qin family, and be good at giving birth and raising", after speaking, he shook it deliberately. Big. Lamp. Widow Qin was also helpless, the Li family's boy's house was too clean, and the same method as dealing with stupid pillars was ineffective for him. If you don't succeed, you can make another plan, and the introduction of the object, whether it is successful or not, is beneficial to yourself, and this is how the friendship is deepened by helping each other.

Li Guocheng knew that what Widow Qin was talking about should be Qin Jingru, watching TV series, she is really beautiful, but her eye sockets are shallow, she did not inherit the shrewdness of the old Qin family, and she was easily damaged by Xu Damao, if it wasn't for the shrewdness of Widow Qin, she would not marry Qin Jingru, it is estimated that this girl's brain is used to maintain her big. Lights up.

"Sister Qin, the family is poor and white, what do you want to marry, plus I am still an apprentice, and I don't have the capital to find a daughter-in-law, I can support myself enough now, but I don't dare to Huo Huo others", Li Guocheng politely refused, the Qin family. Sisters are not their own dishes, one is shrewd, the other is dead, and any of them are enough for people to drink a pot. Coupled with the stupid pillar that is eyeing the tiger, don't think about living a good life in the future.

"It's polite to me, it's decided, I'll bring it over after the year", seeing that there was nothing to pull, he didn't wait for refusal, turned around and left.

"Hey, Sister Qin... Looking at the Qin widow who was leaving quickly, Li Guocheng could only reluctantly give up shouting.

Widow Qin thought as she walked, the heat was not enough, she needed to recuperate slowly, and she had to take out the strength to grind the iron rod into a needle, no matter what, if she had a good relationship with a young, single and lonely guy, she could help her family to some extent. I don't know what came to mind, Widow Qin. The body is a little dry. Hot – it's nice to be young.

Sending away Widow Qin, secretly relieved, how can there be a feeling of being a thief, it seems that both mentally and physically are very honest, don't you just want to be a woman. Someone, hehe smiled secretly, put aside this thought, and instead studied the information.

The drawings are not detailed enough, there is no assembly drawing, only the mapping of some parts, it seems that the factory still does not pay enough attention to the old machine tools, and does not take the time to fully survey. Of course, it is also understood that this model is only a few sporadic units, too old, and not the main model of the factory.

After reading all the information, I reorganized, classified, and constructed in my mind, extracted what I needed, observed carefully, and slowly had the idea of carrying out the next step in my heart.

After a night without words, he went to work the next day, completed his daily tasks, and plunged into the utility room again.

According to the structure diagram in the mind, compare the real thing, remove the walking part one by one, and simultaneously correct the structural assembly diagram in mind, and after 1 hour, the longitudinal guide rail is completely naked. After exposing it and wiping the oil stains on it with silk cotton balls, the potholes and scratches visible to the naked eye remember the traces of the years.

I groped the surface with my hands, felt the potholes and scratches everywhere, released my mental power, and gradually realized in my mind the plan of building the guide rail, and it was clear in a moment that the whole needed to be scraped by 3 mm.

took out a large file from the toolbox, and when the file went down, it was about 2 mm. violently frustrated the rails. If you let others see it, they must think that he is crazy, and on the guide rail with strict accuracy requirements, he actually uses a large file directly, and does not draw lines, does not use a level to measure, and directly hardens.

Generally, fitters above level 5 need to be carefully surveyed and mapped, and then file a little bit with a small file, and measure with various tools from time to time.

Li Guocheng devoted himself wholeheartedly, and after about half an hour, he finally completed the rough machining.

Take out the scraper and start scraping.

Scraping refers to the clamping work of scraping trace metals on the surface of the machined workpiece with a scraper to improve the accuracy of the surface shape and improve the contact between the mating surfaces. Scraping is an important method for the final finishing of various profiles (such as machine tool guide surfaces, connecting surfaces, bearings, mating spheres, etc.) in mechanical licensing and repair. The real function of scraping is to improve the matching accuracy between the parts and improve the oil storage conditions, while the scraping movement, the grinding and extrusion between the workpieces has a certain improvement on the hardness of the workpiece surface, and the small pit left on the surface of the workpiece after scraping can store oil, so that the matching workpiece has enough lubrication in the reciprocating motion, so as not to overheat and cause the phenomenon of brushing.

At this time, Li Guocheng is more focused, for the first time in half a year, there is a phenomenon of sweating, one is too focused, the second is the rapid consumption of mental power, and the third is that you need to maintain a posture when scraping, and you need to pinch the strength, each action level is the same, and the scratches must be consistent.

After more than 2 hours, he finally completed the last knife, stood up and straightened his waist, moved his neck, rattling, the same posture for too long, the investment of brain power, even Li Guocheng's cultivated body was a little unbearable.

Pick up the water glass, knock knock, all dry, good water, give yourself a big thumbs up.

I was admiring my work when I suddenly heard a rough shout: "Is there anyone?" I'm about to turn off the lights."

Li Guocheng walked out of the utility room and saw two people, who were from the security department.

"We patrolled to your workshop and saw that there were lights, thinking that everyone forgot to turn off the lights after work, so we came in and took a look, it's okay, comrade."

"It's okay, I'm working late, I'm too engaged, I've forgotten the time, pack up, and I'll leave immediately," Li Guocheng said apologetically.

Li Guocheng turned around and entered the utility room, and the two members of the security department also tacitly followed in, irradiating all parts of the workshop with flashlights as they walked, and found no abnormality.

Looking at the parts and processing tools on the ground, the two looked at each other and said, "Then hurry up, remember to turn off the lights, turn off the electricity, and close the door when you leave", said the team member with a flashlight, and then the two turned around and left.

"Okay, it's okay right away, it's troublesome for the two", Li Guocheng said politely, watching the two leave, immediately started to clean up, put away the tools, and the parts were already placed when they were disassembled, and a set of 'turn off the lights, turn off the electricity, and close the door', and left the factory quickly.

When I get home, the same buns, the same recipe, after eating and washing, I go to sleep at the end.

On the second day of the freshness test, the taste did not change at all, and it was still so fragrant.

Eating the same meal every day, the older generation of northerners should understand, southerners may not be able to stand it, and are more accustomed to eating different patterns every day.

This is an era of scarce resources, and the only winter dishes are Chinese cabbage stored in winter, plus the cheapest pickle gnocchi, which is delicious. I am thankful that I can eat enough, and I thank the party and the new society from the bottom of my heart.

Li Guocheng has been eating meat buns for the past few days, one is cooked food, the fragrance is not great when heated, and the other is that everyone goes out early and returns late every day, everyone is not at the same point, otherwise if you try, a few uncles may hold an all-staff meeting to criticize you and teach you how to live. Everyone will think that you will eat food and will not live.
