Siheyuan: I live next door to Xu Damao, my last name is Cao

The days passed by.

The news that Sha Zhu was beaten by a woman spread in the steel mill for more than a week, and he was ridiculed for more than a week.

Finally, after searching with Ma Hua, he was unable to find the person who spread his gossip.

Sha Zhu turned his gaze towards the people in the courtyard.

For example, Xu Damao, this guy is mean and he must be involved in this matter.

Sha Zhu silently kept a record of this for him: A gentleman's revenge is never too late, even after ten years; a villain's revenge takes all day long.

Sha Zhu is not a gentleman, so he has been looking for opportunities to take revenge on Xu Damao these days.

Besides Xu Damao, there must be someone else, but Sha Zhu doesn't know who it is, so Sha Zhu can only put all the blame on Xu Damao.

Actually, Xu Damao is still looking for an opportunity to plot against Sha Zhu. After all, he has not yet completed his revenge. After the family is wiped out, they are sworn enemies.

Xu Damao was also thinking of ways to make Sha Zhu even more miserable.

After several days of observation, he finally found some clues.

The steel rolling mill is about to carry out worker-level assessment during this period, and Xu Damao feels that Sha Zhu will definitely participate, so he can make use of this matter and find a way to deal with him.

......

Two days ago, Cao Wei signed in and acquired the locksmith skill, but this time it was level four, which meant that Cao Wei's locksmith skills had officially started.

That’s right, level 4 fitter is the official entry level.

After Cao Wei mastered the fourth level of benchwork, he discovered that the first three levels were really simple. They were just the use of benchwork tools and machine tools to perform rough processing on the workpiece with a considerable amount of tolerance.

After reaching the fourth level of fitter, the requirements for various skills become higher, and the actual operations need to reach a very fine level. For example, the accuracy of file processing can reach plus or minus 0.04 mm. Other chiseling, sawing, scribing, drilling, reaming, tapping and threading (see thread processing), scraping, grinding, straightening, bending and riveting need to reach a certain level.

As for the level of practice, you need to start moving towards level five and begin to study and practice towards a more sophisticated level.

The accuracy that a level 0.02 fitter needs to achieve is 0.04 mm. He must be able to use files to process parts for assembly, and the assembly gap must not be able to accommodate a mm feeler gauge.

The sixth level is 0.01, the seventh level is 0.004, and the final eighth level fitter requires an accuracy of 0.002 mm, which is plus or minus 0.001 mm. This is probably the limit of what the human eye can achieve.

The technical requirements are extremely high, and the basic skills have to reach a level that is unimaginable for ordinary people.

That’s why it is said that an eighth-level fitter can make rockets and airplanes with his hands.

That's quite an awesome existence.

This is getting off topic. At present, Cao Wei is just a second-level fitter. He has the skills of a fourth-level fitter but has not yet passed the assessment.

As for whether or not to continue working in this job, that is another matter. Cao Wei has not made up his mind yet.

Cao Wei planned to wait and see for two years. If the wind was strong, he would run away quickly because he, a small fitter, would be helpless.

During this period, Cao Wei has been working very hard, and both their team leader and workshop director have praised him highly.

The workshop director has noticed Cao Wei's progress. This child doesn't have a master to guide him now, but he studies hard and works very hard.

Moreover, he has a strong ability to learn. From the perspective of basic skills, he is not inferior to some old workers who have been working at the third-level level for many years, and is even better.

Of course, this is exactly the effect Cao Wei wanted.

Otherwise he wouldn't have worked so hard during this period.

When Cao Wei was praised, Jia Dongxu was extremely envious and jealous. He was jealous why he was not the one praised, hated why Cao Wei improved so quickly, and hated Yi Zhonghai for not teaching him anything.

Anyway, Cao Wei lived a very comfortable life.

I signed in with the system these days and received some canned gourmet food. According to the system, these are clean and hygienic delicacies from a thousand years later.

Food that has passed its expiration date cannot be eaten, but Cao Wei didn’t know what this food, which was a thousand years older than its expiration date, meant.

Do you think you can travel through time?

But he still ate it, he firmly believed that the system would not harm him.

You know what, this can is pretty good.

......

Soon, the day of the work-level assessment arrived as scheduled.

The factory was very busy that day, because every workshop was conducting an assessment, so the production line in each workshop was stopped first, otherwise there would be a shortage of manpower and accidents would easily occur.

The factory committee organizes the factory leadership team and senior workers to assess the work level of junior workers, and the trade union supervises the work.

The trade unions of this era were organizations of the working masses, with representatives elected by the workers, so they were relatively fair and just.

Workers in each workshop are assessed in their corresponding workshop. In order to avoid suspicion, senior workers in each workshop will be transferred to other workshops for assessment.

Yi Zhonghai was naturally transferred as well.

However, before leaving, he still said goodbye to others. After all, he had an apprentice who was also clamoring to take the test and even wanted to pass it.

As Yi Zhonghai is very clear about Jia Dongxu's level, if he doesn't say hello,

There are a total of ten people responsible for the work grade assessment of their workshop, including the logistics director Li Huaide, the workshop director of their workshop, a worker representative who is a seventh-level fitter, two fifth-level fitters, one sixth-level fitter, and the rest are from other trades.

Cao Wei first took the assessment for level three fitter. For him, who already had level four fitter skills, processing these ten level three workpieces was very easy. He quickly completed the processing of the workpieces in less than half of the total time.

When he handed the parts to the front, Li Huaide was very surprised. He was very amazed that this young man could process them so quickly. How could they be qualified?

But he didn't make any sound, after all, he was just here to supervise.

A level three fitter is reviewed by two level five fitters.

When Cao Wei handed it over, the two were also surprised. Then they measured it with calipers and were immediately shocked.

Because the ten parts processed by Cao Wei are all perfect third-level parts.

What is a perfect tertiary part?

Level three parts are considered rough processing, and the parts only need to be accurate to within 0.5 mm.

The perfect third-level parts are those that are exactly stuck at 0.5 mm. In fact, this is not uncommon. The important thing is that all the parts processed by Cao Wei are perfect third-level parts.

It seemed that this young man had solid skills, and they estimated that Cao Wei's level was far beyond the third level.

Even if you ask them to do it, they may not all be able to do it.

"Congratulations, you have passed the third-level fitter assessment and become a third-level fitter."

The two level five fitters said with a smile.

"Thank you, examiners."

"Don't thank us, it's your own hard work."
