"Jiang Gong, this is a combined machine tool for priming processing, these machine tools are also the machine tools with the highest precision, these machine tools are the machine tools of Hansi Guo that were bought back in SL at that time, assembled by our engineers, and now they are the treasures in our factory! It is precisely because of this that the production efficiency of our ground fire will be increased exponentially. ”

Hu Dahai pointed to a few machine tools that were different from other machine tools.

Originally, the assembly of a finished bullet was mainly divided into two parts, mainly the cartridge case, that is, the processing of the primer and the assembly of the bullet (the assembly of the cartridge case and the warhead).

The primer of each bullet is the most critical part of the bullet, and if the primer is damaged during production and transportation, it is very likely to have unimaginable consequences at any time.

As early as the founding of the People's Republic of China, China used high-precision combined machine tools in the processing of primer fire, and reduced manual operation as much as possible to improve production efficiency and safety.

After the primer is installed, the machine applies a sealing paint between the primer and the cartridge case at the same time to prevent the primer from getting damp and the bullet from failing.

Seeing that some female workers were inspecting the bullet casings that had been installed on the ground fire, Jiang Yan asked a little curiously.

"This still needs to be checked!"

"That's right! It needs to be checked and those that are not suitable can be picked out before moving on to the next link. ”

After Hu Dahai finished saying this, he explained: "Female workers are more careful than male workers, so to check whether the ground fire has been installed properly, basically female workers are used." ”

After listening to Hu Dahai's explanation, he nodded and did not speak, but Xu Damao next to him looked at these female workers with interest, and the angry Jiang Yan gave him a kick.

"What kind of paint is this?"

Jiang Yan curiously pointed to the worker painting the connection between the bullet casing and the bullet, and asked curiously.

"Oh, they're painted with insulating paint."

Through Hu Dahai's explanation and inspection, it turned out that before the warhead was officially loaded into the shell, the machine tool would apply a layer of sealing paint to the mouth of the shell. After all, metal processing will produce a certain error, and it is difficult to ensure that each cartridge case and the bullet head are so tightly fitted, so the sealing paint can completely isolate the internal and external air and prevent the gunpowder inside the cartridge case from being damp and affecting the performance of the bullet.

After that, the bullet enters the assembly line, and the professional bullet assembly machine tool first pours the weighed propellant into the cartridge case, and finally squeezes the warhead in, and after weighing inspection and appearance testing, a qualified bullet is born.

"It turns out that there are so many processes to produce bullets! I used to think it was too simple. Jiang Yan sighed while holding a bullet that had been manufactured.

"Yes! Boss, I'm also eye-opening today, it's so shocking," Xu Damao next to him said.

"But all the machines here are made from abroad, and I don't know when we will be able to use our own machines to produce bullets."

Hu Dahai also said with emotion.

Hearing Hu Dahai's words, Jiang Yan looked at the busy workers and said, "There will be a day." ”

Hu Dahai heard Jiang Yan's words, and also muttered to himself: "Yes! There will come a day. ”

When people are busy, it seems that this time flies very quickly, from the end of the tour of the bullet production, unconsciously two months have passed, at this time the time has come to July, the weather is gradually getting hotter.

However, the weather in this ice city in July is much better than that of Sijiu City, although it has entered summer, the weather here is still like the weather in April and May, very refreshing.

In these two months, Jiang Yan took the workers to start repairing other machines, with the help of his own space computer, Jiang Yan still restored a few machines, the drawings of these machines were soon studied by a special person and began to experiment in Fengtian No. 1 Machinery Factory, Jiang Yan as a reverse imitation engineer, was also called to guide the work several times, under the guidance of Jiang Yan, the first batch of machine tools were successfully produced by Fengtian No. 1 Machinery Factory, and soon these machine tools were sent to the whole country. This greatly alleviates the lack of machines in the factory.

If you ask Jiang Yan if there are any private goods involved, then the answer must be yes, how can he be worthy of his identity as a traverser without a little private goods.

Jiang Yan also sent the drawings of the CA6140 lathe developed by Fengtian No. 1 Machine Tool Factory in 74 years in the drawings for those imitation machine tools.

CA6140 is a kind of horizontal lathe improved on the basis of the original C620 ordinary machine tool, in the machine tool naming C stands for lathe A is the structural characteristics code, used to distinguish C6140, 6 represents the horizontal type, 1 represents the basic type, 40 represents the maximum rotation diameter of 400MM, is one of the equipment required by mechanical equipment manufacturing enterprises.

CA6140 lathe has complex structure and wide performance, which is suitable for processing all kinds of rotary body parts, and its tool holder can tighten four different turning tools at the same time, and use four different turning tools alternately to process the workpiece by rotating the tool holder under different working conditions.

This machine tool is widely used in later generations, and has a wide range of uses, which can be used for rough machining and finishing of mechanical parts, with reliable structure, convenient operation, economy and practicality. The control system is fully functional and highly reliable. The machine can meet the needs of many industries, such as: automobile, tractor, military, machinery and other industries. The machine tool is especially suitable for high-efficiency and large-scale turning of internal and external cylindrical surfaces, cones, threads, drilling, reaming and curved rotary bodies of shafts and disc parts.

The first machine tool that Jiang Yan came into contact with in later generations was it, and he dismantled this machine tool countless times when he was in school, and Jiang Yan was too familiar with the structure inside, and he could draw its structure with his eyes closed.

The most important thing is that according to the current level of national production, Fengtian No. 1 Machine Tool Factory is fully capable of producing this machine tool, originally this machine tool is the product it is responsible for developing, Jiang Yan will give this machine tool to them, that is, the disguised thing to the original owner.

During the month of these two people, every Sunday, either Jiang Yan went to Hao Pingchuan's house, or Hao Pingchuan came to the factory to pick up Jiang Yan.

I have to say that the boldness of this Northeast person is vividly displayed in Hao Pingchuan's daughter-in-law Yang Xiaomei, every time he goes to his house, he will prepare a lot of Northeast special meals to entertain Jiang Yan and them.

Everyone's monthly meat ticket is limited, even Hao Pingchuan, the director of the public security bureau, is estimated to be not much, Jiang Yan is also very curious about why Hao Pingchuan has so much meat at home, through Yang Xiaomei's explanation, Jiang Yan understands that this Yang Xiaomei's father is an old hunter, and his pistol technique is really amazing, and there are many prey in the forests of Northeast China in this era, and every time he enters the mountains, he will return with a full load, most of the prey is sold to the supply and marketing cooperative, and the rest have become the food in the mouths of his family. This Yang Xiaomei is the only girl in their family, so she is naturally a little more favored, and she gives more things.

Northeast people like to drink, how can there be less wine at every party, Jiang Yan found that this Yang Xiaomei's amount of wine is not much worse than the two of them, but waste wood is still waste wood, Xu Damao still maintains the record of pouring three or two, according to Yang Xiaomei, with Xu Damao's amount of wine, on their side, it is the life of the child's table.
