Siheyuan starts from a better life

Chapter 222, Precision Segment Machine
In the morning, Jiang Yan ate corn porridge. The corn from the Northeast has a sweet taste. After eating it once, Jiang Yan fell in love with it.

The Erhe noodle steamed buns here are not small, one is the size of an adult's fist and weighs about half a catty, so one is 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 these procedures, Jiang Yan and Guo Jianjun came to the workshop where he worked.

Entering the workshop, Jiang Yan looked it up curiously. The workshop was about 100 square meters, and there was a row of tool boxes on the right.

At this time, there is a piece of equipment in the center of the workshop, and a large group of people are surrounding it, and two of them are arguing there.

"Mr. Jiang, this is the workshop where you want to work. We will bring some equipment that can be disassembled here for maintenance and upgrading. Some equipment that cannot be disassembled still needs to be disassembled in the workshop."

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

The two people who were arguing about the location of the equipment heard what Guo Jianjun said, and they didn't care about arguing, put down the guy in their hands, and came to Guo Jianjun and Jiang Yan.

"Jiang Gong, let me introduce you. These two are nine-level engineers Wang Tianlai and Zhang Xiang in our factory. The others are apprentices and workers brought by them."

After Guo Jianjun introduced these two people, he introduced them to the two people who came over.

However, when Jiang Yan heard Wang Tianlai's name, he couldn't help but look at him more. His name was only one name away from his own, Factory Manager Zhang.

"Wang Gong, Zhang Gong, this is Jiang Yan Jiang Gong, an expert who came from Forty-Nine City. He is a seventh-level engineer. He once studied in SL and passed the SL engineer. The oxygen-blowing converter used is something he invented."

Hearing Guo Jianjun's introduction, the eyes of the two of them lit up.

However, those people below are indeed talking about it.

"Is this the expert invited from Forty-Nine City? Why are they so young?"

"It's just too young. Looking at whether he is 20 years old, I feel that he is not much older than my son."

"He shouldn't be here for gold plating! We have a heavy task here, but we can't play house with him."

…………

Such comments also reached Jiang Yan's ears, and Jiang Yan frowned slightly when he heard their comments.

The two engineers saw Jiang Yan's displeasure. Others didn't know, but as engineers, they did know how valuable this SL engineer was.

Most of all the senior engineers in the factory now go to support the establishment of factories in other places, and even the senior engineers, most of them understand Russian and English, and there are not many people who understand German, and the only engineer who is proficient in virtue does not know tuned in there.

The factory also hired a German translator. Since the translator does not understand engineering equipment, the translated things are a bit wrong.

German, like English, is known as general and professional, and the engineering terminology and specialized vocabulary are fundamentally different from ordinary German vocabulary.
Engineering-specific vocabulary refers to those terms and vocabulary that have special meanings in the engineering field. Usually, these terms and specialized vocabulary retain their basic meanings and also have specific meanings in the engineering field.

If you use ordinary German translation to translate some engineering problems, it is naturally wrong.

"What's the noise? Quiet me. If you don't understand, don't talk nonsense. Mr. Jiang is also someone you can talk about. He is the one who designed the oxygen-blowing converter, and his skills are not bad."

Everyone heard Wang Tianlai's words, and the discussion quieted down, but they still looked at Jiang Yan with some distrust.

Technicians, like chefs, rely on their skills to make a living. If they don't do anything, they will probably be looked down upon by this group of people, which will affect their future work.

After thinking of this, Jiang Yan strode to the front where they were researching the machine tool.

When I walked in, I found that this is a fine segment machine produced by Rheinmetall. This type of fine segment machine was specially used to produce the barrels of MP40 submachine guns and Mauser 98k rifles during World War II.

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

The gun barrel is an important part of the gun, and it is also the part with the worst working environment and the highest mechanical performance requirements. The quality of a gun barrel directly affects the service life and performance of the gun, so the processing technology of the gun barrel has also become Particularly important.

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

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

"I haven't opened it to take a look." Jiang Yan asked them strangely.

Hearing Jiang Yan's question, Liu Xiang said something in embarrassment.

"We disassembled relatively few equipment, and we also learned S-type machines. We did little research on German-style machines. We disassembled one before, but we couldn't assemble it no matter how we assembled it."

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

"The machine that was disassembled before is placed there."

Jiang Yan followed his fingers and glanced at the machine in the corner, which seemed to be a metal cutting machine.

"Help me get the wrench, screwdriver and other tools, and prepare some drawing paper and pens for me."

Seeing Jiang Yan getting ready for work, Guo Jianjun on the side hurriedly said, "Mr. Jiang, I'll prepare a work uniform for you."

After saying this, he left in a hurry.

"The German machine is very different from the S machine." Jiang Yan said while taking off his coat.

"In our impression, the S-type sub-machines are relatively rough in design. Most of their machines are not high-precision, but they are easy to maintain. That is what we often call stupid."

"The German machines are just the opposite. Their machines have higher precision, but their machines are also designed to be more precise, so it's not easy to maintain."

While they were talking, Guo Jianjun hurried over with a brand new overalls.

Jiang Yan took the overalls that Guo Jianjun handed over, and put them on directly.

After Jiang Yan put on the overalls, he turned his head to Wang Tianlai and Zhang Xiang who were standing there and said, "Please ask Wang Gong and Zhang Gong to help me for a while, and the wronged two will help me."

Hearing Jiang Yan's words, the two hurriedly said, "No trouble, no trouble. We also want to thank Mr. Jiang for giving us the opportunity to observe on the spot."

"You can ask questions at any time if you don't understand anything. As long as I know something, I will tell you."

Stopping Jiang Yan's words, the two of them were quite pleasantly surprised. Being able to receive guidance from others on the spot was something that no one could have imagined.
