------------------------

Recently, I have received a lot of recommended tickets and monthly passes, especially when I saw many old friends, I was very moved, and I got up early in the morning to add more to everyone to express my gratitude.

------------------------

I thought it was beautiful, I wanted to wake up an hour early, but in fact, the biological clock was still 5 o'clock, and there was no way to go to the park, so I could only continue my daily daily work.

came to the workshop, and after Wang Gong and Master Yi all came, Wang Gong designated a machine tool of the same model for Li Guocheng to perform.

Li Guocheng was not polite, and directly began to disassemble, and the two only had time to take a sip of their own high crush, and then they couldn't close their mouths in surprise from beginning to end. It's too smooth, although the speed has not been significantly improved, but the whole process is obviously smoother, more smooth, has completely surpassed their level, in the process of installation, Li Guocheng always upside down the gear, and then will be on the side of the individual gear somewhere with a scraper to gently cut a few times, not pay attention to see, can not see obvious changes.

This is even more terrifying, I saw the scraping with my own eyes, and the debris also fell from the eyes, but I didn't look carefully in my hand, but I couldn't see the scratches, which shows what it shows that the accuracy of Li Guocheng's processing has surpassed the range of all the measuring tools in the current factory, and it has surpassed the processing accuracy of all senior workers.

That's what a monster is.

The maintenance of the whole machine tool is completed, Wang Gong rushed to start the machine, the result is exactly the same as he thought, the operation is more stable, the noise of the machine tool is less than that of the previous maintenance, and the howling of the motor is excluded.

"How did you do it", Wang Gong seems to have discovered a new world.

"Adjust the center of gravity of the gear, so that the center of gravity of the gear is more balanced, but unfortunately can only be fine-tuned, these gears are worn, and there will be instantaneous jamming when starting, stopping or processing the working part of the workpiece, which will reduce the life of the gear, and will also affect the machining accuracy." Li Guocheng said with regret.

"Where did you learn this?" asked Finish, curious.

"What the Library Sees".

"If you were asked to remachine a set of gears, propeller shafts and lead screws, how much would the machining accuracy of the machine improve?"

"There should be no problem with raising it by an order of magnitude, which is mainly based on the current models, which are relatively new. But our factory has lathes of all ages, most of them are older than my age, most of them are more than guide rail scraping, if other parts are replaced, the workload and input cost is very large, with the current situation of the factory, it is very unrealistic, most of our machine tools have to rely on workers to ensure machining accuracy according to the machine tool familiarity".

"Yes, there is no way, our country is still poor, the application for new equipment in our factory is submitted every year, but every time it is returned, the new equipment needs to ensure key factories and key projects", Wang Gong also said helplessly.

"Alright, let's finish the task according to the plan first. Specific to the improvement of machine tools, I will report to the section chief first, and then I will talk about it then", Wang Gong mentioned a little confidence.

The three of them returned to their respective workstations with their own concerns.

The next day, the three of them got together again, Wang Gong brought good news, you can try to improve one, see the effect, in order to increase the contrast, the target lathe is still the KT200 with a relatively simple structure, and it does not affect the normal scheduling.

Improving machine tools is slow work, and the progress is controlled by Li Guocheng himself.

In the days that followed, when encountering a new model, Master Yi did it first, and then Master Yi and Wang Gong watched Li Guocheng's performance with high crushing. Yes, you heard it right, with the accumulation of experience in disassembly, scraping and assembly, Li Guocheng's skills have become more and more proficient, and he has involuntarily integrated the artistic conception of the five birds in his work, sometimes he is as calm as a bear sitting, getting up like a tiger going down the mountain, quiet as a deer drinking water, light as an ape, and like a bird flying when he goes back and forth to take objects.

In the whole maintenance process, although there is no formal apprenticeship, in fact, everyone tacitly understands that one teaches seriously, and the other learns energetically, not a master and apprentice, but a master and apprentice. With the maintenance progressing, both of them have a heart of love for talents, and they have taught Li Guocheng many years of experience without reservation, so naturally, I don't know which day it started, Li Guocheng officially opened his mouth to shout "master", and his surname was automatically ignored.

Time to return to the day when Wang Gong brought good news.

After Li Guocheng completed today's maintenance work, the trio came to the utility room, which is a special place for machine tool renovation in the future, and was notified, Zhang Tou has brought someone to help clean up in advance, and the electrician also replaced the bulb with a large wattage, and the entire utility room became clean and bright, and a row of storage shelves was placed against the wall, on which various tools were placed. In the middle is a large wooden table of 3 x 2 meters, which is used as a work table.

At this stage of Zhang Tou, everyone is happy, and the better Li Guocheng performs, the happier he is as a master.

For the first time, the trio gathered in the utility room to discuss the next renovation plan.

"Wang Gong, Master Yi, this KT200 is too old, many parts are seriously worn, if the machining accuracy wants to achieve the goal of doubling the highest precision of the factory, most of the parts need to be remade, only the base and guide rail can be retained."

"It's true that tinkering may be saved, but if we remanufacture these parts this time, it will also show that we have the ability to build machine tools, and the benefits are self-evident," Wang Gong muses.

"It's true that in the past, people didn't pay attention to the center of gravity of the components, but this time they can adjust it by themselves, which is also a pioneering initiative," says Master Yi.

"In fact, the view of the center of gravity has long been mentioned in the West, and it was first applied in the motor rotor, and then slowly unified it called dynamic balancing, because the dynamic balancing machine is complex and expensive, and it has not yet been widely used."

"You also saw these from the library," Wang Gong said with a smile.

"Hmm", Li Guocheng was flustered, and the old god was there on the surface.

"I also want to see a perfect machine tool appear in our hands, if all the innovation, it is of great significance to our domestic machine tool manufacturing technology, but before the result, we still have to be cautious", Wang Gong said seriously.

"I agree," Master Yi echoed.

"Listen to the two", Li Guocheng gladly accepted.

"We started to divide the labor, I was responsible for coordinating and drawing drawings, Master Yi was responsible for processing, and then Xiao Li was finishing and assembling, and it would be better if we could get a balancing machine," Wang Gong said with great anticipation.

"No problem".

"Agreed".

Li Guocheng and Master Yi are all in favor.

"Okay, I'll draft a plan first, submit it for review, and after it passes, we'll start working, and Xiao Li can start preparing now."

"Okay, I'll finish the lead screw first."

The three of them "did it" together, Wang Gong and Master Yi made tea and sat down, watching Li Guocheng disassemble it.

After getting off work a little late, after going home, just entered the compound, I felt abnormal, the people in the front yard were gone, and when I entered the middle courtyard, it was clear, the whole hospital meeting, which had been held twice before, were all notices to promote national policies or streets, but today it was obviously different, and the courtyard was noisy.

found a corner, and with Li Guocheng's height, he could just see what was happening inside.

When he saw the three people inside, Li Guocheng knew that today's things were fun.
