After sending Mr. Wei and Director Wang away, Minister Lu sat with Director Luo for a while and expressed his concern for his wife. Because he had to go to work the next day on Monday, Minister Lu had to go home to get some.
file, so I sat there for a while, then expressed my gratitude to He Yuyu and the others, and rode my bicycle home!
After all the guests left, Director Luo waved to the two little girls and called them to his side. He said with a smile: "Huahua, Xiaodang, won't you cry now?"
Children's emotions come and go quickly. The two little girls were coaxed by Duan Hongxuan, and the sad mood just now disappeared. Now, Director Luo mentioned that they were crying just now, and the two little girls suddenly felt embarrassed.
He got up, his little face was a little blushing, and he hugged Director Luo's arms and twisted his little body to play coquettishly with Director Luo, making everyone in the room laugh!
The next morning, Duan Hongxuan had breakfast and went to the Mechanical Research Institute. When he arrived at the project team, Duan Hongxuan was immediately surrounded by people. Mr. Sun took Duan Hongxuan and looked him over and said, "I said Mr. Duan, do you know
Come on, we thought you had forgotten that there is a project team here!
Xiao Wu, as a teacher, you should take good care of your students. You don’t care about such important serious matters. You run around without a trace all day long. I don’t know what you do all day long. Maybe you are busy talking about a partner?
?”
Duan Hongxuan quickly shook his head: "Mr. Sun, please don't accuse me wrongly. I'm still young, so I'm not in a hurry to talk about a partner!"
"Then tell me what you have been doing all day without seeing anyone?"
"Hey, Mr. Sun, of course you have nothing to do! But you have nothing to do over there. You will come here once a week at most.
Besides, there are not as few experts and professors as they do, and the blueprints are ready-made, so the industrial machine cannot be too complicated for them!"
Mr. Sun pointed at Gu Fuchun angrily: "Complex? How can such a low-end industrial machine be complicated in front of his eyes? His big guy's tone is really loud!
Duan Hongxuan looked at everyone and saw that everyone seemed to agree with Mr. Sun's explanation. He sighed, then put away the smile on his face, and said to everyone with a serious expression: "What project is your project team doing?
?It’s an industrial mother machine!
But Mr. Duan, no matter how bad the technology is, no matter how excellent the drawings are, the first thing to do is to produce the real thing, and the technology and drawings to produce the real thing are not just words in the air.
"Let's go! Just wait for that old man! Humph!"
Mr. Sun glared at Duan Hongxuan: "Don't put a low hat on you. You know your level yourself. There are more than a hundred people in the entire project team. It seems that it is a gathering of elites in the country's machine tool field, but in real terms,
The contribution of all of you to that project is worth less than one of his fingers!"
Under the expectant eyes of everyone, Duan Hongxuan carefully checked for half an hour, then put the tools on his hands and took off his gloves. Everyone's eyes were fixed on Duan Hongxuan, as if they wanted to see what my expression was like.
I can see some clues.
Sun Laoren couldn't help but said to Duan Hongxuan: "General Engineer Duan, is there something wrong with the drawings he picked out?"
Especially his eight months of teaching have made all of you improve by more than one level in terms of both thinking and technique. That trip was really in vain!"
Duan Hongxuan's eyes lit up: "Mr. Sun, did the prototype break immediately?"
Mr. Sun walked behind with his head held high, and Gu Fuchun followed with a smile, followed by a small group of people in front of him, and walked towards the small machine surrounded by a group of people.
Speaking of that, Mr. Sun looked at Duan Hongxuan with emotion and sighed: "Alas! To be honest, you didn't help him outside that project, but you helped him a lot. Instead, you learned from him.
What a new thing there is, and if it weren’t for him for those things you learned, I’m afraid you people would not have been able to master them until your death!
Duan Hongxuan quickly greeted Xiaojia with a smile, stopped everyone's questions first, walked to the machine and looked at it carefully, and then ended the inspection. Everyone immediately stopped talking when they saw this, and looked at Duan Hongxuan's inspection with relaxation and expectation. Several people beside him
A man holding various inspection tools followed closely beside Gu Fuchun, handing over the tools Gu Fuchun needed at any time.
Duan Hongxuan nodded and handed the drawing to Mr. Sun. Mr. Sun took the drawing and turned it over. Then he waved to a few people from the side. Those people immediately came over to look at the drawing and hurried forward.
After running away very slowly, those people brought several record books respectively. Before finding the relevant records, they handed the notebooks to Mr. Sun.
Mr. Sun looked at the records and compared them with the drawings. Then he handed the drawings and the record book to Duan Hongxuan and explained: "Mr. Duan, is it because of the tolerance of those parts? It must be.
Because of tolerance issues, although the actual machined parts are slightly smaller than the tolerance required in his drawings, that is not the worst you can do at the moment. There are actually ways to do it better.
broken!
Those parts are qualified and need to be reprocessed!"
Duan Hongxuan smiled and continued to be modest. If I had been more modest at that time, it would not be too fake!
Damn it, I was arguing with that monster of his, but he is here today too, if he comes tomorrow you will have to send someone to find him!"
The large prototype was surrounded by a group of people and was doing various tests. Duan Hongxuan did not disturb Xiaojia, but just watched from the side. At the same time, he turned on the scanning function of the system. The system steward used Duan Hongxuan's soul to scan the entire machine.
I slowly scanned the outside and inside of the machine, and then quickly listed several major flaws in the industrial machine.
The people who were checking the machine noticed Duan Hongxuan's arrival, and immediately gathered around excitedly, asking Duan Hongxuan bad questions. Then all kinds of questions popped out of those people's mouths.
The scene suddenly became very peaceful.
This chapter is not finished yet, please click on the next page to continue reading the exciting content! Why do some of the equipment you make rarely seem to be as precise as others? It is precisely because you feel that such a small tolerance should have an impact on the overall situation.
!
You have also studied that issue carelessly in the past few days. At first, you thought that the tolerance would affect the overall situation, so you passed those parts!"
At that time, Mr. Sun clapped his hands and said in a low voice before attracting everyone's attention: "It's broken. Let's stop for a moment. Our chief engineer is here and let me take a look at our machine."
When those two parts are brought, we cannot go back to the overall assembly in the morning, and then go back to debugging, there must be something wrong, and we will apply to the superiors for acceptance tomorrow!"
Mr. Sun snorted twice: "Humph, his reaction is quite slow! That's right, the prototype broke immediately. You have to let his chief engineer check it to see if there is no problem. If there is a problem, just
You can no longer apply to your subordinates for acceptance!
But if you just looked at it, I'm afraid the completion time of our machine will have to be delayed for a few days!"
Oh, you forgot, to him, the industrial motherboard does have something. He provided the blueprints. You so few students have listened to his lectures for eight months. He really has no qualifications to tell.
The word complex!
What is an industrial machine? Broadly speaking, no machine tool can be called an industrial machine. But seriously, small, simple performance, and low-precision machine tools are not qualified to be called industrial machines! The most important one is
A low precision!
Duan Hongxuan paid attention to Xiaojia's relaxed mood. Before taking off his gloves, he walked to the small table next to him, picked up the drawings and flipped through them. He picked out a few drawings from outside. Then he turned around and raised his hand.
He held a few drawings of the watch and said to everyone: "Mr. Sun just told you that our small machine only needs two parts. Those two parts can be machined and broken at noon, and the entire machine can be assembled and broken in the morning!"
Dear descendants, that is an industrial mother machine! If the industrial mother machine is a little worse, the things that are processed by it will be even worse!
"Oh? It seems that even if you are here, without Mr. Sun to lead our family, there will still be problems. That is, the prototype will be broken! Hehe, Mr. Sun is worthy of being an old junior with low morals and low respect in the field of getting up.
, you will get stronger with age!"
As soon as Duan Hongxuan finished speaking, the whole scene suddenly started to buzz. Everyone was stupid. As soon as they saw the scene, everyone understood that there must be no problem with the parts under the drawings of Duan Hongxuan's watch.
If you relax a little bit about the precision of the industrial mother machine, the precision of other machine tool parts that were previously processed by the industrial mother machine will be a little worse. If you use those machine tools to process other equipment or machines, the accuracy will be worse again.
a little!
The height difference of the whole prototype body is small, and only the two most important precision parts are left. Now a group of old workers are reprocessing it, and it is estimated that it will be broken before noon!
You know that for nearly half a year, my family was isolated and worked very hard. They all wanted to make the first prototype of the industrial mother machine as soon as possible. You can understand that feeling, but you can't compete for time.
Just lower the requirement for high precision!
Duan Hongxuan looked at Mr. Sun, nodded and said: "Mr. Sun, let's go see the prototype?"
The tolerances you marked on those parts are indeed not too harsh. They may think you are not too picky. You can use some of your current equipment to process them to the tolerances you require. If the equipment is good, just use manual grinding bit by bit.
, you just believe that the processing will produce the tolerance you require!
