Chapter 440: Questions about milling machines

Thinking of this, Zhang Lianying confidently said: "Old Chen, you are very careful, but your carefulness is useless. I told you that this drawing was designed by a top military expert in country M. When designing this kind of drawing, the processing range of the machine tool must be taken into consideration. How can someone design a gun that the machine tool cannot process and produce! Aren’t you worrying about it?"
After listening to Zhang Lianying’s words, Chen Dongshan retorted:
Old Zhang, don’t forget that foreign machine tools may be different from our domestic ones! When designing this kind of guns, they only consider those from other military factories. The processing range of the machine tool does not consider the processing range of the machine tool of our military base. Your design drawing is plagiarism from other works. I am afraid that the gun you'designed' looks pretty good, but I'm just worried It will make the workers embarrassed! They may not be able to produce the guns you designed!"
"Hey! Old Chen, you have to worry about it again. Don't look at the advanced weapons developed by Old M, but their machine tools are similar to ours. It's not that advanced machines must be produced to produce advanced weapons. There seems to be no inevitable relationship between the two!" Zhang Lianying heard Chen Dongshan's words, and he was a little dissatisfied, so he pleaded with him again.
"Lao Zhang, what you said has some truth, but don't forget that even the machine tools of our own military bases are not all the same! Some gun parts cannot be processed on our own base, and we have to get another base for processing. Well! You have experienced these things too! Once, the guns you designed by yourself weren’t like that, because one shot couldn’t be processed at our military base, so you had to get another military base. You won’t forget about this. Right!"
Combining some of his previous experiences, Chen Dongshan refuted Zhang Lianying again.
After Zhang Lianying listened to it, he really felt some truth. Because of this, he had indeed experienced it before. Once, the new type of gun he designed could not be produced in his base because of a shooting. In the end, he had to give the production task to another military base not far from their base.
"This---this---this---Old Chen, I said you said I experienced this. It's just that this kind of thing rarely happens. Under normal circumstances, this kind of thing doesn't happen. I didn't think about it at the time, and the size of the shot was designed to be a bit long, so I had to take it to another base for processing.
This is my own mistake. And the military experts of old M are definitely better than ours. Their firearms designers are definitely more professional than ours. I believe that people will not make such low-level mistakes. "
After listening to Chen Dongshan's words, Zhang Lianying still felt that his "plagiarized" guns would not cause any problems in the production process, and they would be produced smoothly.
Chen Dongshan saw that Zhang Lianying was very confident, and he couldn't refute anything any more, so he took another cigarette and smiled: "Okay, I won't fight with you. I hope everything goes well, and we will become both of you soon Hero."
The two quarreled a few words about this matter, and then refuted some words to each other. After that, they shook hands and made peace.
This is the habit of the two old guys. I often quarrel about some things, but in the end I will stand on the same front.
This is the case for the two now, first because there may be problems in the production of the new gun, and they disagree, but soon the two are reconciled again.
Just after the two reconciled, they heard a knock on the door.
"Boom boom!"
"Who, come in!"
At first, the two thought it was Zhao Zhongyao! Because under normal circumstances, Zhao Zhongyao is the one who talks to the two of them. These workers don't have so many things to talk to them.
But when Chen Dongshan got up and opened the door, he saw Zhao Gang standing outside the door.
"Yo! Is it Instructor Zhao! What, is there something!"
Chen Dongshan saw that it was Zhao Gang, and he said politely. In any case, Zhao Gang is considered the most prestigious among these workers. Chen Dongshan and Zhang Lianying can look down on other workers, but they can't look down on Zhao Gang.
"There was a problem in the production of guns. Director Zhao, let me call you over."
Zhao Gang didn't want to say anything to these two old guys, so he explained his intentions directly.
He didn't go into the house at all, just stood at the door and said something.
But this sentence has made Zhang Lianying and Chen Dongshan startled.
When Chen Dongshan heard this, Zhao Gang said that the new gun encountered a little problem in the production process, and immediately wondered if it was a problem with the size of the machine tool. He looked back at Zhang Lianying. Seeing Zhang Lianying, he was sitting there in a daze. Obviously, he did not believe what Zhao Gang had said.
After Zhao Gang saw that he had said this, both Chen Dongshan and Zhang Lianying were stunned. There was no response for a long time, so they repeated: "Two experts, let's go to the workshop! Director Zhao is waiting for you. !"
"Ah! Okay, let's go over immediately."
Only then did Chen Dongshan react, turned around, looked at Zhao Gang and said with a smile.
"Okay, hurry over, ah!"
Zhao Gang was still afraid that these two old guys would not pass, so he increased his tone.
After finishing speaking, Zhao Gang turned and left the office door of Chen Dongshan and Zhang Lianying, and went downstairs to the workshop again.
Chen Dongshan saw that Zhao Gang had gone back. He immediately returned to the office to look at Zhang Lianying and said nervously: "Look, see, how is it, you are not convinced, I have said it!"
Although Chen Dongshan was nervous, just think about it. What he had just talked with Zhang Lianying had proved that his worries were correct, and he would naturally start talking about Zhang Lianying again.
"Is it because they don't understand the drawings? Let's explain to them!" Zhang Lianying was still not convinced. He wondered if Zhao Gang and the others didn't know much about the drawings, and they violated the drawings to produce weapons in the production process.
Because in the process of producing weapons, there will be some workers who are not careful in their operations, and the data on the drawings are not clearly recorded. In this way, in the production process, the processing range of the machine tool and the size of the gun parts in the mind of the workers will naturally appear. The situation is not the same.
In such a situation, some workers who do not know the skills will feel that there is a problem with the design of the drawings. Just want to put the responsibility on the designer!
"Impossible! Zhao Gang can still look at the drawings, and, as he said just now, it was Zhao Zhongyao who called us over! This shows that Zhao Zhongyao already knows the problems in the production process, could he? You still don’t understand the drawings we designed. Don’t forget, Zhao Zhongyao is a military expert and a weapon designer himself!"
Chen Dongshan saw that Zhang Lianying still believed that there was no problem with the drawings he designed, and he was a little dissatisfied, so he defended Zhang Lianying again.
"Old Chen, don't talk too much nonsense. Let's go to the workshop to see, and we won't know." At this time, Zhang Lianying was not in the mood to fight with Chen Dongshan, and wanted to see if there was a problem.
The two hurriedly left their office and walked downstairs to the workshop.
Soon the two came to the experimental workshop where the new gun was produced.
The two of them saw that Zhao Zhongyao, Zhao Gang, and a few workers were standing in front of a milling machine, discussing something, so they walked over.
When several workers saw that two old experts were coming, they naturally stepped aside and let Zhang Lianying and Chen Dongshan come to the front of the milling machine.
At the beginning, Zhang Lianying looked at the milling machine in front of him. He still didn't understand what was going on. He also wondered, could it be that the machine was malfunctioning. If that were the case, he, a firearms expert, might not even understand it. A professional machine technician is required.
"Director Zhao, is there a problem with this machine tool?" As soon as Zhang Lianying came to Zhao Zhongyao, before Zhao Zhongyao asked him, he pretended to ask Zhao Zhongyao first.
As soon as Zhao Zhongyao heard Zhang Lianying's words, he sneered and said, "Hehe! Expert Zhang, if you say that the milling machine has a problem, why should I call you a firearms expert? I can just find the master who repairs this machine."
"That's the problem. Is it the raw material for the barrel. I have nothing to do with it. There is only this kind of steel in our country. There is no better one. If you want to use better steel, then It has to be imported! Only the country M has more durable alloy steel. We do not have this technology and cannot produce such high-purity alloy steel. We can only use this ordinary steel to produce gun barrels."
Zhang Lianying was originally a particularly self-righteous person. He saw that Zhao Zhongyao said that it was not a machine tool problem, and immediately thought it was a steel problem, so he got a lot of words.
When Zhao Zhongyao heard this, he was really angry. He increased his tone and looked at Zhang Lianying and said, "Expert Zhang, do you think I will come to you if these problems arise? I am looking for you, it must be with Xin Gun Is there any question about the design drawings?"
"What, there is a problem with the design drawings, how is this possible! Director Zhao, my design drawings have been approved by the superiors, and everything is qualified. How can you say that there is a problem with my design drawings."
Zhang Lianying immediately became unhappy when he heard Zhao Zhongyao say that there was a problem with his design, and asked himself a few words of excuse.
"There are some problems. It's not that someone made the mistake intentionally. It's just that there may be some objective reasons that we didn't think of. Expert Zhang, your design is very good. The new guns are indeed very advanced. It's just your new gun. The barrel on the design drawing is nearly 100mm longer than the ordinary barrel.
Regardless of this small gap of ten centimeters, our milling machine will not be able to complete the barrel task of the new gun you designed! Take a look for yourself! The barrel of your new gun is too long, and the drill bit of this milling machine has a maximum processing depth of 500mm. And the barrel of the new gun you designed reaches 508mm.
In this case, this milling machine will not be able to complete the ‘opening’ of your barrel anyway. Can't rifle, then what use is this barrel? It's not like a piece of scrap iron. "
Zhao Zhongyao saw that Zhang Lianying was deliberately arguing with himself and was unwilling to talk about the subject, so he had to personally pull Zhang Lianying to the point, asking him to take a good look at what happened to the barrel on the milling machine in front of him.
Zhang Lianying pretended to look at the barrel on the milling machine in front of him. Then he blushed and said, "Oh, it turned out to be the problem! But the new gun I designed, his biggest feature is that the range is better than ordinary rifles It’s one or two hundred meters away! How to do this is to work the barrel! If the barrel is not longer than an ordinary barrel, then how can it be longer than an ordinary rifle in range."
Naturally, Zhang Lianying did not want to say that the guns he designed were not very good. In the face of Zhao Zhongyao and the group of workers, he still said that the guns he designed were the most advanced and more powerful than ordinary rifles. It is unavoidable that the barrel is longer.
"Gong Zhang, what you said is very good. We design weapons. Naturally, we want to make our new weapons design better in power and range than the original weapons. This is also a normal way of thinking.
It's just that we are going to produce these three new experimental guns immediately, and this milling machine can't complete this work, you say, what should we do now! "
Zhao Zhongyao saw that Zhang Lianying didn't talk about the shortcomings of the guns he designed, but just said how advanced the guns he designed were compared to ordinary rifles. He had to put this difficult contradiction in front of Zhang Lianying.
Zhang Lianying looked at the milling machine in front of him, and he thought for a while and said, "Or, take these three barrels to the gun base of the final assembly for production! There may be a large milling machine that can process such barrels."
When Zhao Zhongyao heard this, he shook his head and said, "Mr. Zhang, you came from the base of the final assembly. Do you have a large milling machine in your base? It's not all the same as this one. Let's talk about it. This milling machine is already a large one. As far as I know, in our country, there is no milling machine one size bigger than this."
Zhao Zhongyao has been engaged in the military industry for two years, and he has a good understanding of the various domestic military machine tools. He knows that there is no milling machine one size bigger in China's military industry base.
After Zhao Zhongyao finished speaking, he looked at Zhang Lianying. I saw Zhang Lianying, just quietly looking at the milling machine in front of him, as if thinking about something.
Because of Zhao Zhongyao’s words, he has no way to refute. He is also an expert in military industry, and he is quite familiar with the domestic machine tool situation. This type of milling machine is already the largest, and there is no milling machine one size larger. Up.
Chen Dongshan never said anything. Because, in his office, he had already debated with Zhang Lianying on this issue in advance. But Zhang Lianying was very unconvinced. Now when I arrived at the scene, Chen Dongshan really encountered such a problem.
