After Jiang Yan and the three of them exchanged pleasantries, he took them to the work table where he worked, took out one of the many drawings and handed it to Sun Deshui.

"Master Sun, look at the parts on this drawing, can you make them."

Jiang Yan's drawings for Sun Deshui are the two most important of all the parts, and the parts on this drawing are the ball screws of the finishing machine.

Ball screws are ideal for converting rotary motion into linear motion, or for converting linear motion into rotary motion. Ball screws are the most commonly used transmission elements in tool machinery and precision machinery, and their main function is to convert rotary motion into linear motion, or torque into axial repetitive force, and at the same time have the characteristics of high precision, reversibility and high efficiency. Due to their low frictional resistance, ball screws are widely used in a variety of industrial equipment and precision instruments.

The ball screw is composed of a screw, a nut, a steel ball, a pre-pressed sheet, a reverser, and a dust preventer. Its function is to convert the rotational motion into linear motion, which is a further extension and development of the Eckham screw, and the significance of this development is to change the bearing from a sliding action to a rolling action.

"This picture is beautiful, it looks comfortable" Seeing the drawing, Sun Deshui praised first.

Hearing Sun Deshui's words, Jiang Yan hurriedly spoke modestly, "Master Sun, you have it." ”

After Jiang Yan finished saying this, he didn't speak, and waited for him quietly.

"It's a little difficult, but it shouldn't be a problem."

Hearing Sun Deshui say that he could do it, Jiang Yan breathed a sigh of relief in his heart.

Jiang Yan pointed to the drawings and said to Sun Deshui: "Master Sun, here, here, and here, these three positions are all difficult points in processing. ”

"When manufacturing, the integrity of the screw must be ensured", otherwise it will be difficult to put it in the machine. ”

"And the polishing of the screw after the manufacture is completed must be extremely careful, and the wire ring on the screw must not be damaged, otherwise the screw will be wasted."

After Jiang Yan finished saying this, he spoke again.

"Master Sun, I will mark these places for you on the drawings later."

Jiang Yan's words, Sun Deshui grinned.

"Don't worry! Jiang Gong, I made this thing once, and there is absolutely no problem. ”

Sun Deshui, who was holding a tool in his hand, was extremely confident, and his body exuded the confidence of being an eighth-level worker.

The machine tool made a resonant sound, Jiang Yan stood next to watch Sun Deshui control the machine tool, how to produce the knife, how to withdraw the knife, Jiang Yan felt that the machine tool was alive in his hands.

The screw began to take shape in the resonance of the machine.

As Sun Deshui's two senior apprentices, the two of them were also there to watch their master's operation intently, and they frowned when they had time.

For them, it is also a rare thing to be able to observe the manufacturing of an eighth-level worker on site, and it is also a good opportunity for them to learn.

It is rare for a high-level worker to be able to complete the entire part, even if they don't have a machine tool.

They can also rely on the simple work of hammers, scissors, files, sandpaper, etc. It's just a little bit longer.

In other words, it is not an exaggeration to say that senior workers are almost omnipotent.

When Jiang Yan was in a daze, Guo Jianjun walked in from the outside, followed by two people, who were holding two trays with many bottles and cans on them.

"Jiang Gong." Hearing Guo Jianjun call himself, Jiang Yan's gaze was taken back from the machine.

Jiang Yan glanced at what they were holding and asked.

"I've bought them all."

"Yes, according to the documents you gave me, these things have been bought, but Jiang Gong, don't say it, there are some things that our factory doesn't have, and this is something I bought when I took someone to Bingcheng."

While Guo Jianjun was speaking, Jiang Yan was looking at the things they brought over and nodded.

"Jiang Gong, what should we do next?" Guo Jianjun asked again.

Jiang Yan fiddled with the things he brought over, and said without raising his head: "You go find a few iron buckets, and I'll test their effects first." ”

"If you can, you can take someone to dig a big pit here in the past two days, and then paste it with cement, but if you really want to start operating, you don't have enough of this thing, at least ten times the amount."

"Don't worry, Jiang Gong, as long as there is an effect, don't say ten times the amount, a hundred times the amount, I will find a way to get it for you, I have reported this matter to the factory director and secretary, and they fully support it." Hearing Jiang Yan's words, Guo Jianjun agreed.

"Zhang Gong, Wang Gong, let's take a hand!" Jiang Yan opened his mouth to the two people who were standing there looking at the pile of bottles and cans with interest.

"Can we go over?" Wang Tianlai asked a little strangely.

In this era, the master and apprentice still have to keep a hand, not to mention those precious formulas, many of these things are not passed on secrets, and even if they are passed on, there are strict regulations.

From the beginning, Jiang Yan wanted to mix these chemical cleaners by himself, Wang Tianlai and Zhang Xiang didn't plan to follow suit, this thing is much more precious than the secret recipe, and their family and Jiang Yan are not familiar with it, why would others pass it on to themselves.

In the past two days, I have been grateful to be able to follow Jiang Yan to learn some ways to disassemble the machine tool, for the formula of these things, the two of them did not dare to have ideas at all, just now I heard Jiang Yan call them, the two of them were very surprised.

"It's not you two or who! Come and help, don't you want to? At this time, Jiang Yan's words were a little impatient, and he did a job grinding and chirping.

However, the two of them completely ignored Jiang Yan's impatience, and instead of a look of joy.

"By the way, Wang Gong, you said before that you have a set of imported industrial-grade balance weights, borrow them from me, you can't pick the door!"

Hearing Jiang Yan's words, Wang Tianlai hurriedly spoke: "Don't be stingy, definitely not stingy, I'll go and bring it to you, you can use it for as long as you want." I don't feel sorry to send you. ”

As he said this, he walked outside the workshop, some of them in a hurry, as if he was being picked up by a dog behind his butt.

"This Wang Gong is still in a hurry." Looking at Wang Tianlai, who was in a hurry, Jiang Yan said casually.

Wang Tianlai's performance really made Zhang Xiang, who was standing where he was watching, fall through his glasses, Wang Tianlai and his set of industrial-grade balance weights were not less to show off in front of colleagues, others wanted to borrow a lot of good things, and he didn't see him so generous today.

"Zhang Gong, I want to trouble you to take someone to sign out of a place and where to put these big buckets."

Immediately afterwards, Jiang Yan ordered Zhang Xiang to be where he is now.

At this time, Guo Jianjun, who was now next to them, spoke: "Don't bother Zhang Gong, I'll take someone to vacate that space." ”

As he spoke, he waved to the few people who were following behind him who were sending barrels, and a few people started to work in a hurry.

"Jiang Gong, what else can I do." Seeing that his job was robbed, Zhang Xiang asked again.

Hearing Zhang Xiang's words, Jiang Yan thought about it, and decided to take him to pick out those parts with serious stains and clean them later.

There are a few people in the workshop, doing their own work in an orderly manner.
