At six o'clock, the whistle finally blew. Tired but full of a sense of accomplishment poured out of the workshop, ready to end the day's work and return home. Everyone's faces were filled with proud smiles, and their chins were raised high, showing their enthusiasm and confidence in their work. Even if you are covered in oil, you can't hide your optimistic mental outlook.

At this time, the entire streets of Sijiu City were filled with workers wearing the uniforms of various factories, forming a unique scenery.

Workers are in groups of three or five, enthusiastically discussing the completion of today's production indicators in the workshop.

"Lao Zhang, how many products have we processed with this machine tool today?"

"I made 58 pieces by hand, what about you?"

"I have 65 pieces! Make persistent efforts and strive to catch up with the eagle as soon as possible!"

The eyes of the workers are full of longing and pride, and they sincerely feel happy and glorious for the progress of the motherland. They are all proud of their work, because everyone is building the motherland in earnest.

Jiang Yan had already packed his things at this time and was ready to go home, the car was already waiting below, his "nephew" had now become He Yuzhu's car, the motorcycle was ridden away by Liuzi, and Xu Damao and Shi were afraid that it would not affect well, and now they are both riding bicycles to and from work.

"Leader, go home or go to the Aviation Bureau." Jiang Yan just got in the car and asked his driver.

"Go home," Jiang Yan said, and sat in the back and closed his eyes to recuperate.

After a period of exercise, now Sirui has begun to take over the project, these few days are the period when their department tackles a project, and now she basically eats and lives in the Aviation Bureau, and she has no time to date Jiang Yan.

When the rolling mill workers were almost gone, Yan Jiecheng, who had finished a day's work, finally returned home dejectedly. As soon as they entered the door, the third master and the people in the family smelled Yan Jiecheng's pungent smell, and they almost vomited when they smelled this smell, and their faces showed unhappy expressions.

Yan Jiedi pinched her nose even more exaggeratedly and hid to the side.

"Xie Cheng, what's the matter with this smell on your body? Fell into the manure pit," the third master, Yan Bugui, asked with a frown.

Yan Jiecheng sat on the chair and told the story of what had happened in the past two days indignantly, and when he talked about Jiang Yan, it was even more difficult to hide his resentment in his tone.

"You shut up for me, it's all someone else's problem, you haven't thought about your own problem, if you don't get distracted, will there be something like that? After deducting a year's salary, you haven't calculated much money, you, you're angry with me. As soon as he heard that Yan Jiecheng had been deducted from his salary for a year, and he only had a subsidy of ten yuan a month, Yan Bugui was completely angry.

This Yan Jiecheng is a second-level worker, he can get 41.5 this month, and now he only has 10 yuan left a month, and he has been transferred to the logistics to clean the toilet, and he has lost more than 400 yuan inside and outside this year, which makes Yan Bugui how acceptable.

"Old man, I thought, isn't this machine also repaired by Jiang Yan, it shouldn't be too much of a problem, otherwise you go to Jiang Yan to intercede, see if you can get rid of the punishment of our family, and by the way, transfer him back to the workshop, the difference between the wages of this worker and the sweeper is big." The three mothers said on the side interface.

"It's Dad, just go to Jiang Yan and talk to him, doesn't he respect you very much? Let's see if I can fix things with my brother. That's a lot of money! Let me tell you, Jiang Yan is now more face-saving, and many people are begging him, and my brother's matter is not a matter of his words. Yan Jiefang interjected.

Where is this Yan Jiefang so kind, he has his own little Jiujiu in his heart, if Jiang Yan and his brother's affairs are done, then he can also let his old man go to Jiang Yan to intercede, and see if he can get an official and a half-position in the research institute.

Not to mention that the Yan family will calculate! And that's where the calculations begin.

"Okay, I'll take a look after eating in a while, Xie Cheng, you go wash and let's eat first, the old woman brought the two bottles of Fenjiu that my students gave me, and I'll send them to Jiang Yan after eating." Yan Bugui opened his mouth and said.

"This, two bottles of wine is not too much, I think it's almost the same to send one bottle." The three mothers looked at the three masters, Yan Bugui, and said a word in their mouths.

"What do you know, your hair is long and your knowledge is short, you can listen to me, and Xie Cheng, this is a thing for you, this bottle of Fenjiu is sold for 6 yuan in the supply and marketing cooperative, and you also need a wine ticket, I don't want your Laozi wine ticket, you can give me 20 yuan, and I will pay me back when I am paid." Yan Bugui said.

"Dad, without you doing this, ten yuan is about the same. I still have to hand over my salary to you after this month, so I don't have much money left. As soon as he heard that two bottles of wine cost twenty yuan, Yan Jiecheng was directly anxious.

"So be it! Who called me your old man! Fifteen dollars, but you pay us three more dollars a month in the future. Yan Bugui opened his mouth quite shrewdly.

For a while, Yan Jiecheng and Yan Bugui had a verbal battle, and the bargaining between you and me finally ended up with 13 yuan and two yuan more than a month.

The camera shifted to Jiang Yan's side. After Jiang Yan returned home for dinner, he said hello to He Yuzhu and the others, and he came directly to his study, and after plugging in the door of the study, Jiang Yan came to his own space, turned on the computer and began to work there.

Jiang Yan took into account that now the technicians are also learning, and they are idle, so they can use this time to design and transform the existing machine tools in advance, so that they can practice in advance, and in this way, they can first look at the drawings and understand the structure, and then it will be easier to assemble the actual machine tools.

So Jiang Yan turned out the blank design drawings and prepared to draw. He first sketched the overall structural framework of the machine with a pencil, labeled the individual parts of the machine, and then began to design the spindle head components in detail, calculating the appropriate speed ratio and torque.

Due to the help of the computer, Jiang Yan's calculation was also much faster, and soon the speed ratio and torque of the machine tool were calculated in detail by Jiang Yan, and Jiang Yan wrote the calculated numbers on the drawings in detail.

After calculating these, Jiang Yan looked at the drawings, the head was a big one, and then he had to draw the schematic diagram of the design of the CNC system and mark the way of circuit connection.

It is also necessary to carefully calculate the size of the bed bed, adopt a box-shaped structure, increase the internal ribs, and improve the rigidity.

In order to facilitate tool change, it is necessary to design an automatic tool magazine, which can be used with a robot to achieve fast tool change, and at the same time, the machine bed system must be redesigned.

In order to increase the rigidity, the cast steel structure was used instead to replace the previous cast iron structure, in short, it was a large system engineering.

However, these Jiang Yan can also calculate some basic general directions, as for the accurate calculation, you still need to accept the group of technicians to do it.

I did it all, what did those technicians under my command do, and how to train them.

The so-called master leads the door to practice in an individual, and there is nothing wrong with doing it himself.

Jiang Yan put down the paintbrush and moved his stiff fingers and wrists, these new machine tool design drawings have basically been completed, and I believe that it will provide great help for the learning of technicians.

Looking at the freshly baked drawings, Jiang Yan nodded with satisfaction.
