Chapter 222, Fine Segmenting Machine

As early as Jiang Yan had eaten corn porridge, the corn from the Northeast had the sweet taste of soybean. After eating it once, Jiang Yan fell in love with it.

The steamed buns with noodles he sells are not small in size. One is about the size of an adult's fist and weighs almost half a catty. It's enough for Jiang Yan's appetite.

After breakfast, Guo Jianjun took Jiang Yan to the security department to apply for a special pass. After completing the procedures, Jiang Yan and Guo Jianjun went to the workshop where he worked.

Entering the workshop, Jiang Yan looked at everything curiously. The workshop was about more than 100 square meters, and there was a row of tool boxes on the right side.

At this time, there was a piece of equipment in the center of the workshop, and a large group of people were surrounding it. Two of them were arguing over something.

"Gong Jiang, that's the workshop where I want to work. They will take some removable equipment there for maintenance and upgrading. Some equipment that cannot be removed requires me to go to the workshop to disassemble it."

After Guo Jianjun finished speaking, he shouted at the large group of people inside: "Gong Wang, Gong Zhang, the experts from Sijiu City are here, come here quickly."

When the two people who were arguing about where the equipment was, heard Guo Jianjun's words, they ignored the argument and walked over to the guy in front of Guo Jianjun and Jiang Yan.

"Gong Jiang, come and introduce me to someone. These two are Wang Tianlai and Zhang Xiang, the ninth-level engineers in our factory. The others are their apprentices and workers."

After Guo Jianjun introduced the two people, he introduced the two people who came over by mistake.

When Jiang Yan heard Wang Tianlai's name, he couldn't help but take a second look at him. There was only one difference between his name and his own, Factory Director Zhang.

"Gong Wang, Gong Zhang, that is the expert Jiang Yan who came from 49 cities. He is a seventh-level engineer. He has studied abroad in SL and passed the SL engineer exam. He is proficient in English, Russian, and German. Our factory

The oxygen blowing converter used in it is not something he invented."

Upon hearing Guo Jianjun's introduction, the two people's eyes lit up.

Those people east of Bu Nao were indeed talking about it.

"Then we are experts invited from 49 cities? Why are you so young?"

"Is he too young? He looks like he is twenty years old. He feels that he is not much older than his son."

"Then he won't come here to do the gilding, right? We have a heavy task there, and there's no way we can play house with him."

…………

That kind of discussion also reached Jiang Yan's ears, and Jiang Yan frowned slightly when he heard their discussion.

The two Weidai engineers saw Jiang Yan's displeasure. They didn't know that as engineers, they knew exactly how valuable the SL engineer was.

Most of the senior engineers outside the Ruming factory go to support the establishment of factories in other places, and even if they are senior engineers, most of them understand Russian and English. There are not many people who understand German, and the only engineer who is proficient in virtue is not

I know where it's tuned.

We also hired a German translator outside the factory, but because the translator didn't understand engineering equipment, the translation was a bit confusing.

German, like English, is known as general and professional. The engineering terminology and special vocabulary are essentially different from ordinary German vocabulary.

Engineering-specific vocabulary refers to those terms and vocabulary that have specialized meanings in the engineering field. Usually those terms and vocabulary have specific meanings in the engineering field in addition to retaining their basic meanings.

If I use ordinary German translation to translate some engineering issues, it will naturally be wrong.

"Why are you making so much noise? Just give him some peace. Don't talk nonsense if you don't understand. Jiang Gong is not someone we can discuss. Did he design someone who blows the oxygen converter? His legs are not very good."

After hearing Wang Tianlai's words, everyone's chatter became quieter. Bu Nao still looked at Jiang Yan with some distrust.

Technicians, like chefs, rely on their skills to make a living. If you don't do anything to ask for permission, you will probably be looked down upon by that group of people. If you make a mistake, your future work will be affected, and it is inevitable that some people will violate it.

After thinking about that, Jiang Yan strode to the front of the machine tool where they were studying.

When I walked in, I discovered that it was a fine segmenting machine produced by Rheinmetall. During World War II, this kind of fine segmenting machine was specially used to produce the barrels of MP40 submachine guns and Mauser 98k rifles.

It can process three types of rifling: equal rifling, progressive rifling and mixed rifling. The accuracy is quite high, and it was a very good machine throughout World War II.

The barrel is not the most important part of the firearm, nor is it the part of the entire gun that has the harshest working environment and the highest mechanical requirements. The quality of a barrel directly affects the service life and performance of the gun, so the quality of the barrel

The processing technology has also become particularly demanding.

"What's the problem with that?" Jiang Yan turned around and asked Wang Tianlai when he saw the fine segmenting machine.

"It is speculated that there is a problem with the bearing inside. Every time it rotates, there will be a harsh sound inside."

"I didn't open it to take a look." Jiang Yan asked them strangely.

After hearing Jiang Yan's question, Liu Xiang said something rather embarrassed.

"They have disassembled less equipment, and they have not learned much about S-type machines. They have done little research on German-style machines. They have disassembled one before, but they couldn't put it back together no matter how hard they assemble it."

After speaking, he pointed to the machine in the corner of the workshop.

"The machines that were disassembled before are placed over there."

Jiang Yan followed his leg fingers and glanced at the machine in the corner. It looked like it was a metal cutting machine.

"Bring him a wrench, screwdriver, and other tools, and prepare some drawing paper and pens for him."

Seeing Jiang Yan getting ready for work, Guo Jianjun, who was on the side now, quickly said: "Jiang, go and prepare some work clothes for me."

After saying that, he left in a hurry.

"There is a big difference between German-style machines and S-style machines." Jiang Yan said as he took off his coat.

"In their impression, the design of S-type inflators is relatively rough. Most of their injectors are not very accurate and easy to maintain, which is why they often say they are stupid, big and thick."

"German machinery is just the opposite. The precision of their machinery is relatively high. Their machines are also designed to be more precise, so they are not easy to maintain."

While he was talking, Guo Jianjun hurriedly came over with a brand new piece of jewelry.

Jiang Yan took the work clothes from Guo Jianjun and put them on directly.

After Jiang Yan put on his work clothes, Wang Tianlai and Zhang Xiang, who were standing there, turned around and said, "It's very troublesome. Please help Wang Gong and Zhang Gong to help him. I feel sorry for you two to give him a leg."

Hearing Jiang Yan's words, the two people quickly said: "No trouble, no trouble, they would like to thank Mr. Jiang for allowing them to observe the Fat Wang meeting live."

“Whenever you don’t understand something, you can always ask questions and ask him to tell us what he knows.”

Stopping at Jiang Yan's words, the two of them were quite surprised, and received their on-site guidance, which was something that many people could not have imagined.
