Super manufacturing empire

"The final finishing of that set of spindles can't reach the design precision?" As soon as Yun Kai got off the plane, She Hongwen hurriedly introduced him to the situation, and he frowned.

This set of spindles is specially designed for Xingmeng 9 according to China's top manufacturing capabilities. Although it is very difficult to process, it is not impossible. You must know that at the beginning, this processing technology was provided.

"Didn't I provide you with the complete processing technology? If it's only a little too short, there is no problem. At most, the speed does not need to be that high..." Yun Kai said depressed.

He thought that something big had happened, but such a thing was not a trivial matter, and it could affect the progress of the entire task.He was anxious, these guys at the base were more anxious than him.Once the production task is being hooked up, it is not a simple matter. If it is delayed, it may even be sentenced.

Hearing Yun Kai's words, and looking at his only frown, Zeng Yong couldn't help but smile wryly: "Mr Yun, there is really no way to achieve accuracy, mainly because the stress caused by finishing is not passed before the final super-precision machining. Natural aging is long enough, and the amount of deformation and the position of the deformation of artificial aging are beyond control..."

According to the processing function provided by Yunkai at the beginning, before the final super processing, it takes more than three months for natural aging. The main shaft is hoisted horizontally and allowed to sag naturally in the air, plus some artificially created simulations. In various environments with high temperature and severe cold wind, sun and rain, the amount of deformation can be controlled to a very small range.

Then it will be refined manually by workers.There is no problem with barely reaching the accuracy of the design.

However, now the entire construction period has been shortened by six months, all of which are shortened natural aging time.This natural aging time is already the most basic thing.There is no more now. After the final processing is completed, the stress between the atomic structure of the material and the processing stress are basically still left in the inside of the part. After the processing is completed, it is affected by the environment and problems are likely to occur.

What is terrible is that this main axis is not just a whole as usual.It is formed by the assembly of three spindle sleeves!

Once deformed, this will affect the assembly accuracy, and thus affect the final speed of the entire spindle, use efficiency, and manufacturing accuracy...

"What is the main problem now?" This is what Yun Kai is most concerned about.

Only when the root cause of the problem is found can we make targeted improvements in the process.

"After repairing the deformed part, the wall thickness of the entire spindle will be uneven. If the wall thickness is uniform, the maximum ground deformation exceeds 5μ..." Zeng Yong said with a wry smile.

Those foreign spindles can reach 180,000 revolutions per minute.They are all single-spindles, which are very thick and thin, so there is no such problem. The spindle system they are currently engaged in is made up of three spindles with a wall thickness of only 7 mm...

Relatively speaking, it can be regarded as a thin-walled part.Thin-walled parts.The biggest processing problem is the control of deformation.

For precision spindles, the higher the speed, the stricter the control of the amount of deformation. Generally, the allowable amount of deformation of the spindle that can reach about 80,000 revolutions is only within 0.2μ.A thicker spindle can control this, but it is very easy.Even if the dynamic balance is done at the end, the place that will cause the imbalance of the spindle to rotate at high speed is used to remove the material so that the entire spindle maintains stable operation in the new high-speed rotation.Because the wall is thick enough, there is no need to worry about what will happen.

But the spindle system of this set of drawings provided by Yunkai is obviously not working.

Dynamic balance is only a detection method. There is no way to use the method of removing material to ensure that it will not be deformed due to uneven thickness under high-speed rotation of 300,000 revolutions per minute...

"Let’s take a look at the site first, and then give me the final test data. I will send it to my boss and let them see what’s going on..." Yun Kai is a master, but on this, his Compared with Zeng Yong, the technology is still far behind.

"Okay, one set has been scrapped at the site, and there are two spare sets, but we don't dare to carry out trial processing now..." She Hongwen said with a wry smile, such a set has always been working overtime. Come out, the material cost is only 20,000 to 30,000 yuan, but the processing fee is more than 500,000 yuan!

When it comes to the last process, the 500,000 yuan is gone.

That spindle can only sell scrap iron.The current price of scrap iron is one piece of 81 kilograms, and the remaining weight of a set of spindles can still be bought for more than 30 yuan...

"Number nine, number nine, are you there?" Yun Kai had no way of doing this.

The only way to find Xingmeng No. 9 was the manufacturing process that was changed last time because of this grandson. He also said that they have a way to solve the process problem that lacks natural aging.For such difficult manufacturing, Yunkai himself has no ability to solve it.

"What's the matter? Uncle is annoying..." The painful voice of Xingmeng No. 9 sounded in Yun Kai's mind.

I don't know if I have been listening for a long time, the nerves have adapted to his metal rubbing sound, and Yun Kai does not have the slightest adverse reaction to his voice now.

"You said that when you broke the program, what is the trouble? You don't need to earn money to support your family, and there is no female program to make you soak. What are you worrying about? Last time you didn't mean process improvement. Parts were processed due to residual stress. Can the deformation caused be resolved? I need you to resolve it now..." Yun Kai countered silently.

"Did you give you the control system and the smart chip last time? Didn't that metal potion be delivered to you together?" Xingmeng 9 said dissatisfiedly.

"I'm going, you don't have a list of things to send. By the way, Uncle Nine, where did you send these things from?" Yun Kai was really speechless.

For those control systems, from Yunsu to the base, he has not opened the packing box to check what's inside.

He has never dared to disassemble linear motors and control chips too early to let people know.Otherwise, the technicians in the base would disassemble him for research when they were idle and bored, and they would not be able to recover in the end.Didn't he have to cry to death?

Especially when he saw the cannon fodder robots in the 003 base, he was even more worried about the loss of these chips.

Xingmeng 9 said that the chip was a small number of spare chips on the Xingmeng battleship. Yun Kai guessed that it was probably the control center of these cannon fodder robots!

"Then the metal potion can solve these problems?" Yun Kai obviously didn't believe the words of the nine.

"Even these cannon fodder robots must use this synthetic potion in the production process, otherwise how can ordinary metal materials support such violent movements?" Xingmeng Nine despised Yun Kai.

This kid is too ignorant.

"How to use that potion?"

"After the final precision machining process, keep the overall wall thickness consistent, and the error is not allowed to exceed 0.1μ. The deformation does not exceed 5μ, and the surface of the part is directly coated with that kind of liquid. After waiting for two hours, the liquid will be completely immersed in the molecules. The gap between them will change the various properties of the material..." Xingmeng 9 once again gave Yunkaike a lesson.

"Which potion is so powerful? Can it be produced on earth?" Yun Kai's eyes suddenly lighted.

Isn't it possible to use any ordinary materials to make some parts with very strict material requirements?

"Strictly speaking, this kind of potion is a kind of super bacteria that parasitizes some advanced metals. There are only a few planets in the entire galaxy that can be born. The environmental requirements are very harsh, but in the high-level The key components of space battleships and space fighters are used a lot. If it weren’t for this industrial door’s main machine, which is related to the subsequent manufacturing process, such a precious potion would never be used on such junk equipment..."Xingmeng The tone of Number Nine was full of regret.

"Couldn't this kind of bacteria be cultivated?" Yun Kai was stunned.

"Yes, but the environmental requirements are particularly demanding. The medical cabin on the Star Dream has always been cultivated on a large scale, but now there is not enough energy on the battleship to support large-scale cultivation. This bacterial individual is very small, Even the humans on Earth can manufacture the microscope with the greatest magnification, and they cannot be found out. The volume is countless times smaller than the structure of water molecules..."

"You mean this thing will die soon after entering the interior of ordinary metal?" Yun Kai was stunned.

"Of course. How else do they change the properties of the material? The metals containing them, whether it is hardness or toughness, are inherently contradictory properties and cannot be perfectly combined..."

Yun Kai had to sigh with emotion the magic of this universe.

There are such amazing species.

"Lao She, where are the goods that belonged to me last time?" Since Xingmeng No. 9 is so reliable, there is no way I can't believe him right now?

Anyway, it’s like this now, otherwise, it’s just re-production according to the original process, which is too late in time.

He also didn't believe that Xingmeng No. 9 would make fun of him...

"Aren't those things equipped by your Xingmeng? You said you don't want to move it. After being transported to the warehouse of the base, no one has moved..." She Hongwen asked Yun Kai in amazement.

No one knows what is in those tightly packed things.

Yun Kai has never allowed anyone to move around.

"Except for the amount of deformation, there is nothing wrong with the size of the scrapped set, right?" If there is no problem with this set of spindles that they have determined to be scrapped, at least a lot of time will be saved.

ps: Thank you for holding the slender jojo sleep big evaluation vote.

I'm very sorry that today's update is only out now.

As soon as I turned on the computer in the morning, I saw someone in the book review area saying plagiarism, which made Hulu depressed all morning.Next time, who will say that the gourd is plagiarism, take out the evidence, and just open your mouth!

In addition, some free goods say that Hulu is not dedicated. Hulu is in front of the computer for more than ten hours every day. This is called not dedicated?As for what gunship helicopters cannot carry people, please check whether the multi-purpose gunships like Mi 35 and Mi 24 can carry people before they spray.

Let's spray it after you figure it out.

Hulu is now full-time and the subscription is not high. Will Hulu not be dedicated?The cold has not been well for more than ten days now. It is because of lack of rest. If you don’t support it, don’t talk about it, but spray it randomly. Is it interesting?

As for the other big jump order, Hulu can only say that Hulu has its own settings for this book.You said that you talked about the 101 base at the end of the last chapter. The front is all nonsense. Do you know why Hulu writes this content?Is the gourd really to make up the word count?

If you want to make up the number of characters and directly use the hoist to master the professional machinery industry, it is no problem to easily 3,000 characters in an hour!
