054 Serious problems encountered in the production of samples
"Lao Zhangtou, what you said is very philosophical!" The young man next to him handed Lao Zhangtou a cigarette again, "Give us some suggestions and see if we can use his east wind to make progress......"
Lao Zhangtou's son-in-law is engaged in scientific research in the ministry, and he has been in the same office with everyone for so many years, and he is also kind, and he has never had any conflicts with anyone.
is about to retire, so everyone naturally wants to have more experience.
Who doesn't want to progress?
The base is a small closed society, and if you want to leave, there is only one way, and that is to jump out and transfer to another unit.
The old Zhangtou son-in-law was assigned to the base that year and then transferred out.
The people at the base are all transferred from within the space systems from all parts of the country, and they don't know who their relatives are in a higher position somewhere, or maybe they will ask for something else that day.
"Come, come, you all come here, the old man will tell you today......" Lao Zhangtou got a cigarette, and the young students really wanted to be motivated, so they no longer took the shelf......
Ye Xin ran to workshop 39 and went directly to the data room.
It turned out that no one.
"Avoiding me?" Ye Xin, who was angry, went directly to the 39 workshop, and finally didn't ask where Liu Yue went in the workshop, so he could only go back in a huff. "If you can run, the monk can't run the temple, sooner or later one day will clean you up!"
When everyone in the workshop saw a beautiful girl coming to Liu Yue, they talked about it.
Wang Jinde pricked up his ears when he heard Ye Xin ask Liu Yue at the door of the workshop.
After taking a look, I couldn't help but compare this girl with my little queen Dongmei, and found that Wang Dongmei did not have an advantage in appearance, in terms of temperament, her daughter is still young, a high school student, what kind of temperament can she have?
And the reason why Liu Yue rejected his little girl was that Wang Dongmei was too young, and he was 7 years older than Wang Dongmei!
It's unacceptable!
When Wang Jinde thought of this, his whole person was in a bad mood.
"Bang~"
The chuck of the lathe, which was spinning at high speed, collided with the tool holder.
Under the impetuousness, Wang Jinde, an eighth-level lathe worker, actually made the lowest mistake in the workshop - hitting the knife!
"What's the matter, Lao Wang, you're not hurt, are you?" Zhao Deming suddenly became nervous.
It's okay to scrap parts, anyway, the sample trial production has budgeted a high scrap rate, especially for high-precision work.
It's okay if the lathe is broken, Wang Jinde's eighth-level car, let alone repair it himself, as long as he gives him tools, it's not a matter to make one by himself.
Level 8 turners cannot be injured.
Baby pimple.
"It's okay, I'm distracted. Wang Jinde sighed and put down the work in his hand directly.
At this point, I can't go on.
Thinking that the data clerk of the 79 workshop came to Liu Yue angrily just now, Zhao Deming instantly understood.
"It's nothing, the information clerk of the 79 workshop, it seems that Liu Yue didn't apologize when he provoked her! Just now in the factory director's office, Liu Yue ran away,......" Zhao Deming comforted Wang Jinde.
"This girl doesn't like words!" Wang Jinde lost such a sentence and ran to smoke alone.
He had to figure out a way to get the raw rice to mature as soon as possible.
Even if it's not cooked, you have to put the rice in the pot.
"Lao Wang, why don't you go to my office to talk?" Zhao Deming asked Wang Jinde, "It's decided early, everyone has a bottom in their hearts." ”
Wang Jinde naturally did not reject it, and took the lead in going to the workshop director's office......
During this time, Liu Yue almost took the data room as his home, and in order to facilitate his work, he even ran to get himself a wire bed and put it in the corner of the data room.
I'm usually in the data room, and I hardly leave it except for going to the toilet.
Of course, sometimes I go to the production line to discuss the processing technology of some complex parts with Wang Jinde and others.
Some designs are difficult to produce, there is no top-level CNC equipment, to ensure accuracy and quality, and the understanding of the front-line operators is not very in place, it is easy to have problems in processing, Liu Yue naturally has to discuss with the top national treasure-level technicians.
But he was too tired during this time, and after communicating with Zhou Rong, he ran back to the dormitory where he hadn't been back for a long time and fell asleep.
This sleep was already the next morning, and he was woken up by Zhao Deming's knock on the door.
"No matter how bad the technology in the factory is, the actual situation must be considered in terms of processing technology!
Liu Yue took the production process documents sent by the factory, waved and asked Zhao Deming.
Even if he has only been practicing for a few months in a front-line workshop like 39, he is very angry when he sees this process document.
The process documents prepared by the technical department are simply impractical!
"Whether it is the sequence of processing processes, or the process method, according to the process document processing, there is no way to guarantee the accuracy!" Zhao Deming is also very helpless, the process specification is issued by the technical department, requiring the workshop to process in strict accordance with the process regulations.
It was because the design requirements could not be guaranteed after processing that he came to Liu Yue.
"Liu Yue, you are now a person from the technical department, and you are still the vice president of the factory, it is useless for me to go to them for this matter...... Why don't you talk to them?"
Zhao Deming looked at Liu Yue in embarrassment.
The director of the factory asked him not to disturb Comrade Liu Yue's rest.
"Many of the technicians in the technical department do not understand the situation of the workshop, but only prepare process documents based on the original experience...... The previous process documents have been used for more than 20 years......" Zhao Deming saw Liu Yue looking at him suspiciously, and explained.
It's not that he is willing to disturb Liu Yue, but that he, the workshop director, went to the technical department, which is useless.
"There hasn't been such a problem before, has it?" Liu Yue scratched his head.
No matter how bad the level of the technicians in the technical department is, it will not reach this level.
The technical department is not only in charge of the design, but also has to produce the production drawing according to the design drawing, decompose it into the processing drawing of each process according to the production process and process, and write the process requirements on it.
In the process diagram, there is no range of various processing parameters, and even various tooling, fixtures, measuring tools and other process equipment, equipment models, all need to be indicated.
But looking at the process documents in front of you, all kinds of preparations are no problem, in the arrangement of some processing processes, even Liu Yue, a person who has only been in contact with ordinary machine tool processing for a few months, understands that it is completely wrong!
According to the process regulations issued by the technical department, the final accuracy can not be guaranteed, and there is only one result for all products to be produced - scrapped!
You know, this batch of individual anti-tank rocket launchers produced is all samples!
Sample!
Any military equipment, when producing samples, must not tolerate the existence of any problems that can be discovered.
Once something goes wrong, it's a fatal thing.
Liu Yue could only clean himself up indiscriminately and follow Zhao Deming to the workshop.
"The products we made before were designed many years ago. For so many years, the process documents will not be easily changed unless there is a problem. Even if there is a problem, it has long been changed...... Our factory has never developed a new product......"
Faced with Liu Yue's doubts, Wang Mingliang gave an explanation.
Liu Yue was even more puzzled, "The process has remained unchanged for so many years, what does the technical department do?"
He was incomprehensible.
Isn't the production process based on the continuous accumulation of experience in the production process?
Wang Mingliang looked bitter, "Don't say anything else, before the 107 single rocket launcher machining, the process documents issued by the technical department have problems, I have found the process team, they said no problem, you were busy in those days, I didn't dare to bother you with these little things...... In addition, when the workshop originally produced the first batch of samples, the process documents were not used, and the technical department did not ask about our production process...... Now in mass production, due to the tight time and heavy tasks, their process documents are sent down seven or eight days after the start of production, and they all enter the finishing process at that time...... Now I haven't followed their process documents......"
Wang Mingming's words made Liu Yue realize the seriousness of the problem.
