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

This set of spindles is specially designed by Xingmeng No. 9 according to the level of Huaxia's top manufacturing capacity, although it is very difficult to process, it is not impossible, you must know that at the beginning, this processing technology is provided.

"Didn't we provide you with a complete processing process? If it's just a little bit worse, there's no problem, at most, it won't need to be that high......" Yun Kai said depressedly.

He thought something big was wrong, but it wasn't a small thing, and it could affect the progress of the entire mission. He was in a hurry, and these guys at the base were in a more hurry than him. Once the production task is hooked, it is not a simple matter, and it may even be sentenced if it is delayed.

Hearing Yun Kai's words, and then looking at his brows that were only locked together, Zeng Yong couldn't help but smile bitterly: "Mr. Yun, there is indeed no way to achieve accuracy, mainly because before the final level of precision machining, the stress generated by finishing has not gone through a long enough time to natural aging, and the amount of deformation and deformation position of artificial aging cannot be controlled......"

According to the processing effect provided by Yunkai at the beginning, before the final stage processing, it takes more than three months to have a natural aging, hang the spindle horizontally, let it naturally sag in the air, and add some artificial creation of some environments that simulate various high temperatures, severe cold, wind, sun and rain, the deformation can be controlled to a very small range.

Then it is finished by hand. There is nothing wrong with barely achieving the precision of the design.

However, the entire construction period has now been shortened by six months, all of which is a shortened natural timeliness. This natural aging time is already the most basic thing. Nowadays, after the final processing is completed, because the stress between the atomic structure of the material and the processing stress are basically still left in the interior of the part, after the processing is completed, it is easy to have problems due to the influence of the environment.

Sadly, this spindle is not just a monolithic like the conventional. Rather, it is formed by the assembly of three spindle sleeves!

Once deformed, this will affect the assembly accuracy, and thus affect the degree of the entire spindle at the end, as well as the use efficiency and manufacturing accuracy......

"What's the main problem now?" This is what Yunkai is most concerned about.

Only when the root cause of the problem is found, can the process be improved in a targeted manner.

"After the deformation is repaired, the wall thickness of the entire spindle is uneven, if the wall thickness is guaranteed to be uniform, the maximum deformation is more than 5μ......," Zeng Yong said with a wry smile.

Those spindles abroad that can reach 180,000 revolutions per minute. They are all single spindles, very thick and thick, there will be no such problems at all, and the spindle system they are currently engaged in is assembled by three spindle sleeves 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 problem of controlling the amount of deformation.

The higher the rotation of the precision spindle, the stricter the control of the deformation, and the allowable deformation of the spindle that can reach about 80,000 revolutions is generally only within o.2μ. The thicker spindle can control this, but it is very easy. Even if the dynamic balance is done at the end, the parts that will cause the imbalance of the spindle when the spindle rotates high are used to remove the shape of the material, so that the whole spindle can maintain a stable operation in the high-tech rotation. Because the wall thickness is sufficient, there is no need to worry about what will happen.

However, the spindle system of this set of drawings provided by Yunkai is obviously not good.

Dynamic balancing is only a means of detection, and there is no way to use the method of removing materials to ensure that it will not be deformed due to uneven thickness under high rotation of 300,000 revolutions per minute......

"Let's go to the scene first, and give me the final test number when the time comes, and I'll give it to my boss and let them see what's going on......" Yun Kai is a master is true, but in this regard, his skills are still very poor compared to Zeng Yong.

"Okay, one set has been scrapped on site, and there are two sets of spare, but we don't dare to do trial processing now...... "She Hongwen said with a wry smile, just such a set, it has always been overtime to rush out, the cost of materials is only twenty or thirty thousand yuan, but the processing fee is more than 500,000 yuan!

By the last process, the 500,000 was gone.

That spindle can only be sold for scrap iron. At present, the price of scrap iron is eighty-one kilograms, and the remaining weight of a set of spindles can still be bought for more than 30 yuan......

"Nine, nine, are you there?" Yun Kai didn't have any way to do this.

Only looking for Xingmeng No. 9, 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 of lack of natural aging. For such a difficult manufacturing, Yunkai himself has little ability to solve it.

"What's the matter? Uncle is annoying...... "The egg-wrenching voice of Star Dream Nine sounded in Yun Kai's mind.

I don't know if it's because I've been listening to it for a long time, my nerves have adapted to his metal rubbing sound, and Yun Kai doesn't have the slightest adverse reaction to his voice now.

"What's the trouble you say you have broken the program? You don't need to earn money to support your family, and you don't have a female program for you to soak, so what's your trouble? Didn't you say last time that the process was improved, and the deformation caused by residual stress in the processing process of the part could be solved? It's up to you to solve it now......" Yun Kai fought back speechlessly.

"Did you give you the control of the zhì system and the smart chip last time? Didn't that metal-enhancing potion come with you? Dream Nine said dissatisfied.

"I'll go, you don't have a list of things to send or anything, anyway, Uncle Nine, where did you send all these things from?" Yun Kai was really a little speechless.

Those control systems or something, from Yun Su to the base, he didn't open the box to check what was inside.

Linear motors, control chips or something, he has never dared to disassemble it too early to let people know. Otherwise, these technicians at the base would have taken him apart and studied it when he was idle and bored, and in the end he would not be able to recover. Didn't he have to cry to death?

Especially when he saw the cannon fodder machines in the OO3 base, he was even more worried about the loss of these chips.

Xingmeng 9 said that the chip is a small number of spare chips on the Xingmeng battleship, Yun Kai guessed, it is very likely that it is the control center of these cannon fodder machines!

"Then a metal-enhanced potion will solve these problems?" Yun Kai obviously didn't believe Nine's words.

"Even those cannon fodder machines must use this synthetic potion in the production process, otherwise how can ordinary metal materials still support such a violent movement?" Xingmeng No. 9 despised Yun Kai.

This kid is so uninformed.

"How do you use that potion?"

"After the final precision machining process, the overall wall thickness is kept consistent, and the error is not allowed to exceed o.1μ. The amount of deformation is only 5μ, directly apply the potion to the surface of the part, and after waiting for two hours, the potion will completely immerse itself in the gap between the molecules, thus changing the various properties of the material...... "Xingmeng 9 gave Yunkai a science popularization again.

"What potion is so strong? Can the earth produce it? Yun Kai's eyes lit up.

Isn't it possible to make some parts with very strict material requirements for materials with such an anti-heaven thing?

"This potion, strictly speaking. It is a class bacterium that parasitizes on some high-grade metals, and there are only a few planets in the entire galaxy that are capable of being born. It is very demanding for the environment, but it is used a lot in high-level space warships and space fighters and other key components. If it weren't for the fact that this industrial door machine was related to the subsequent manufacturing process, such a precious potion would never have been used on such a garbage device......" Dream Nine's tone was full of regret.

"Can't this bacterium be cultivated?" Yun Kai was stunned.

"Yes, but it's very demanding for the environment. The medical pod on the Dream has been cultivating on a large scale, but now there is not enough energy on the battleship to support large-scale cultivation at all. The bacteria are so small that even the largest magnification microscope that humans on Earth can currently make can find them. The volume is countless times smaller than the structure of water molecules......"

"You mean this thing will die soon after it enters the plain metal?" Yun Kai was stunned.

"Of course. How else do they change the properties of the material? The metals that contain them, both in hardness and toughness, are inherently contradictory properties that cannot be perfectly combined......"

Yun Kai had to sigh at the magic of this universe.

There is such a miraculous species.

"Lao She, where are the goods that belonged to me last time?" Since what Xingmeng No. 9 said is so reliable, there is nothing to do if you don't believe him at this time, right?

Anyway, that's what it looks like now, otherwise, it will have to be reproduced according to the original process, which is simply too late in time.

He didn't believe that Dream Nine would tease him with idle eggs......

"Aren't those things you Star Dream equips all of? You said don't move, no one has moved since it was transported to the warehouse of the base......" She Hongwen asked Yun Kai in amazement.

No one knows what's in those tightly packaged things.

Yun Kai has always allowed anyone to move.

"Except for the amount of deformation, there is nothing wrong with the other dimensions of the scrapped set, right?" If there is no problem with this set of spindles, which they have already judged to be scrapped, at least it will save a lot of time.

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

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

As soon as I turned on the computer in the morning, I saw that someone in the book review area said that it was plagiarized, which made Hulu depressed all morning. Next time, whoever says gourd plagiarism, take out the evidence, don't spray it when you open your mouth!

In addition, there are free goods to say that the gourd is not dedicated, and the gourd is in front of the computer for more than ten hours every day, which is called disrespect? As for saying that helicopter gunships can't carry people, please check whether multi-purpose gunships like the Mi-35 and Mi-24 can carry people before spraying.

Let's spray after figuring it out for yourself.

Hulu is now full-time, the subscription is not high, does Hulu dare to be dedicated? The cold has not been good for more than ten days now, just because of lack of rest, you don't support it, don't say it, and spray indiscriminately, is it interesting?

As for the other big jump, Hulu can only say that this book, Hulu has its own setting. You said that the last chapter only talked about the 1o1 base, and the front was all nonsense, do you know why Hulu wrote these contents? Could it be that the gourd is really to make up the word count?

If you want to make up the number of words directly with the gourd to master the professional machinery industry, there is no problem with 3,000 words an hour easily!
