"There is no problem with this, the drawings of the modification plan are in my home, as for the machine operation and maintenance manual, I will strive to compile it in the next few days, and I will go to the factory tomorrow morning to demonstrate to you the operation method of the new machine!" Duan Yun heard this, and happily agreed.

Duan Yun has always been a person who does not profit and does not get up early, but this time the main factory has promoted himself to become an engineer and let him take the position of deputy section chief, so Duan Yun must also show his sincerity, and only by contributing to the factory can he convince the public.

But Duan Yun also understands the truth of teaching apprentices to starve to death of masters, he wants to have a stable position in the factory, and he must have technology that cannot be replaced by others, so naturally he can't provide all the technologies to the factory without reservation.

The development of the operation and maintenance manual, the operation is actually very simple, the processing of different specifications of gear, only need to press the button combination on the CNC board, it is completely foolish operation.

As for the explanation of the maintenance part, Duan Yun mainly compiles the mechanical aspects, in fact, even if Duan Yun does not say the changes in the machinery, it can be clarified by Cheng Changlin and some technical masters in the factory for a period of time, so Duan Yun is better to make it public generously than hide it.

Moreover, making an operation and maintenance manual can also save a lot of your own trouble, otherwise you will have to find yourself if there is a little problem with the machine in the future, which is a waste of time and energy.

And the electronic version, especially in terms of chip circuits, this is the core technology that Duan Yun has mastered, Duan Yun will definitely not write all of them in the manual in this regard, he only needs to write a little skin, which is enough for Cheng Changlin and his gang to study for a period of time.

"That's great!" Cheng Changlin patted Duan Yun's shoulder excitedly and said, "You really did a good job this time, and after your mother is discharged from the hospital, you can often come to my house as a guest, and I welcome you very much......"

Unlike Duan Yun's first visit to Cheng Qingyan's house, this time Cheng Changlin rarely faced Duan Yun with a smile on his face, and he also took the initiative to invite Duan Yun to his home as a guest.

Obviously, Duan Yun's technical transformation shocked Cheng Changlin very much, Duan Yun's technical level was at least a big cut beyond himself, and the technology of electronic circuits alone was beyond his reach.

This time he took the initiative to invite Duan Yun, in fact, Cheng Changlin was not only to master the technology of the CNC gear hobbing machine, but also a very important factor was that Cheng Changlin was completely convinced of Duan Yun's technical level, and it also made Cheng Changlin feel that his core position in the factory was shaken for the first time, so as a technical worker, I also wanted to communicate with Duan Yun more in the future to discuss some technology-related issues.

I also have a lot of technical questions that I want to discuss with you, Uncle Cheng. Duan Yun said modestly.

"What a good boy. Yang Xiufang on the side praised her when she heard this.

Although Yang Xiufang is engaged in literary and artistic propaganda in the factory, she has also heard a lot of rumors about Duan Yun's technical transformation recently, especially Duan Yun's modification of the gear hobbing machine, which has caused a sensation in the factory again, in the eyes of many people, Duan Yun's mechanical technology is undoubtedly the best in the factory.

As for her husband, although he is the chief engineer in the factory, but Duan Yun has not come for so many years, although she has also seen that her husband works very hard, but he has never made any major technical transformation plans, from this point of view, although Yang Xiufang is towards her husband, she can only admit that Duan Yun should be higher than her husband in terms of technology.

So when he heard that Duan Yun wanted to ask her husband for advice, this was obviously a humble word.

"Slow down that way. Cheng Changlin said with a smile.

"Mom and Dad, we're gone. Cheng Qingyan waved her hand and got on Duan Yun's motorcycle.

The next moment, Duan Yun unscrewed the accelerator and quickly left the community......

......

After sending Cheng Qingyan to school, Duan Yun asked for leave from the correspondence station in the evening and accompanied his mother at night.

Patients are generally not allowed to bring their own electric blankets in hospitals, but after Duan Yun stuffed two big unity sheets for the head nurse, no one cared about it at all.

Gao Xiuzhi on the hospital bed was still very weak, but it was not so painful.

Fortunately, Duan Yun asked the anesthesiologist to add a little more dose, otherwise, as soon as the anesthetic during the operation passed, the wound would begin to hurt, and more anesthetic would at least make the mother suffer less.

My mother likes to watch TV at home, but this ward doesn't have that, but if you have a radio, you can relieve your loneliness.

At night, the radio said that there were a lot of cross talks, and it was not enough for Duan Yun to change the channel directly when he heard the cross talk program, because he was worried that if his mother laughed after listening to cross talk, she would pull the wound that had just been sewn.

It wasn't until about nine o'clock in the evening, after his mother fell asleep, that Duan Yun left the ward and rode a motorcycle to the night school to pick up Cheng Qingyan, who was about to get out of class.

Cheng Qingyan also took notes very carefully in class, and helped Duan Yun draw the key points of the course in his books, and handed them to Duan Yun after class at night, so that he could study during the day when he had nothing to do in the hospital.

There was no place to sleep in the hospital at night, so Duan Yun could only go back to his new home and guide his sister's work by the way.

Duan Yun soon found that although he said that he had taken leave from the factory, there were more things to do in his usual life.

Early the next morning, according to the agreement with Cheng Changlin, Duan Yun came to the factory to demonstrate the operation method of his modified gear hobbing machine.

A workshop was crowded.

In addition to Qin Gang, Zhao Dongsheng and others, the grassroots management of other workshops also came to the first workshop to watch.

At noon yesterday, Duan Yun's exceptional promotion to engineer was announced on the propaganda board at the gate of the factory, and Duan Yun became the youngest engineer in the history of the Red Star Gear Factory.

At this point, Duan Yun has become a legend in the factory, and the speed of promotion is comparable to that of a rocket, no one would have thought that he was just a small porter in the material preparation workshop when he first entered the factory half a year ago, and after half a year, he actually became an engineer in the factory, became a model worker, divided a new house, and went abroad!

So this time, many people came to a workshop to visit the gear hobbing machine, but in fact, they all wanted to come to see Duan Yun, a legendary figure in the factory.

The process of testing the machine equipment is so simple that it is staggering, Duan Yun just asked the cooperating workers to put the semi-finished tooth embryos on the feeding rack, glanced at the drawings, and pressed a few buttons on the CNC board, and the machine began to run automatically.

Although Qin Gang, Zhao Dongsheng and Cheng Changlin already knew that the processing efficiency of Duan Yun's modified machine was amazing, when they saw that the processing efficiency of this machine was so fast, it was still somewhat beyond their imagination.
