"The largest deformation of the spindle sleeve in the middle of the scrapped spindle is 8μ, and the thickness error is the largest o.3μ, which is too far from the technical requirements on the drawings, and there is no way to modify ......it," Zeng Yong replied to Yun Kai's words.

If such a problem occurs only on the outer circle of the outermost sleeve, it is not a problem at all, because the outer sleeve does not need to rotate, but the two sleeves inside use the electromagnetic principle to rotate in opposite directions, so as to increase the rotation to 300,000 revolutions in stages.

This principle is used in the electric spindle of CNC machine tools, which has not yet appeared in the current world.

In other words, this set of spindles actually does not need precision bearings!

Once there is a deformation, it will make the gap between the three sleeves with small gaps that cannot be seen by the naked eye become uneven, so that there will be a collision, and when the tool installed in the middle of the spindle processes the parts, there is a force acting on the spindle, and the uneven magnetic field becomes more chaotic through the guò lever principle, resulting in the scrapping of the spindle......

"That's really scrapped, it's hopeless. If there is no problem with the other inner coats and outerwear, add another middle coat material. Let's take a look at the scene first. Yun Kai nodded.

It's not a problem to waste hundreds of thousands of processing fees, but the most important thing now is the problem of time.

What was supposed to be a hundred-year task must now be completed in twenty years.

The entire base was stopped because of a problem with the production of this set of spindles. The various aircraft parts that were being processed in the base were also stopped because of the progress problem. Just because love is contagious.

The top jobs of the entire base are gathered to discuss how to solve the problem. As a result, everyone's mood is not very good.

If you're in a bad mood, you're going to make a mistake in your work.

The base has always had a very low scrap rate. In just a few days of the Chinese New Year, millions of parts have been scrapped......

That's basically the amount of scrap in the original month.

A few people soon entered the base production workshop deep in the mountain, in the empty workshop, there was no figure, and when it came to the largest finishing workshop, Yun Kai appeared, on the fitter table outside the warehouse near the office, there were three cylindrical parts with a smooth surface like a mirror. When you get closer, you can see your own shadow reflected on it.

The appearance is very good.

"Those are the three?" Yun Kai sighed, if it was an ordinary part that was put outside, it was not a part of the matter at all, and it could only be reduced to a price for those iron shavings.

"The thickness of the other two pieces is taken as one hundred symmetry points, relative to the benchmark size, the maximum thickness difference is o.4μ, and the minimum is o.o2μ. The place with the largest amount of deformation is five μ three, and the difference in deformation is too much......" Zeng Yong explained to Yun Kai.

In the past, when undertaking the processing of this set of parts, the cost was theirs, and Yunkai only needed the finished product to pay the processing fee, but now the base belongs to Yunkai, and all the costs are borne by Yunkai. He had to let Yun Kai know how these parts were scrapped.

"Arrange people, and immediately start trial processing another set. At that time, the main thing is to ensure that the thickness and size are consistent, the allowable error is only o.25μ, and the deformation is controlled to less than 4μ5......" Yun Kai opened the computer bag in his hand, took out the computer, and pretended to look at the three-dimensional assembly drawing and parts drawing again. sighed again and instructed She Hongwen.

Parts with such precision. Basically, it's not something that can be processed by human beings, but there's no way, even if it's filed with a file, it has to be processed. The files in the hands of the fitters in this base are the most powerful artifacts in the machining industry.

Many high-precision cutting-edge parts are filed raw with the files in their hands.

The 1o1 base may be the most efficient place in the whole of Huaxia, since Yunkai, the boss, has said it and agreed to the difference, given the range of difference, there is no pressure at all. Of course, with such a small tolerance range, it is not easy to process.

"The key parts of the roller screw and guide rail have been completed, right?" She Hongwen went to inform people to start working, and Yun Kai was led by Zeng Yong to the warehouse.

"We produce it ourselves, those products processed by your Xingmeng Machinery Wang Jinshan said that they have been processed, all kinds of large castings Hongqi Machinery Factory has entered the finished product warehouse, and it will be loaded and transported to the base tonight, as a whole, it is just this set of spindles and the finishing control system and branch motors you provide over there, which we can't produce......"

Zeng Yong held a palm-sized silver-gray terminal of the base management system in his hand, opened the production progress tracking sheet on it, and said to Yun Kai.

"There aren't many processing tasks on the Dream Machine's side, right? Didn't you say that they should hand it over to the finished product warehouse of Hongqi Machinery Factory and come over together? "Before the Chinese New Year, Yunkai went back to talk about the relocation of Dream Machinery, and he didn't have time to ask about the production situation at all, and he originally planned to ask them about the production progress when he went to kTV to do activities after dinner.

Dream Machinery still has 132 and a lot of production tasks in other factories, and these jobs must wait until the New Year to collect fake Yunkai to communicate with their outsourcing leaders.

Otherwise, things will be in trouble, and these production tasks must be completed before they can be relocated.

"I don't know the specific situation, I'll call Hongqi Machinery Factory in a while, if they don't send Hongqi Machinery, you can only wait for you to bring it yourself......" Zeng Yong said to Yun Kai as he walked.

Yun Kai nodded, didn't speak again, and followed Zeng Yong directly into the warehouse.

The production progress tracking of various parts is mainly to see what process the various parts have been processed, so that the assembly can be arranged.

Regardless of whether there is a problem with this set of spindles, after those large main castings are delivered to the base tonight, they will enter the assembly process tomorrow.

"I'll go, what are these ball screws hanging like this?" As soon as he entered the warehouse, Yun Kai saw that on a shelf in the corner of the warehouse, a row of ball screws of different lengths and arm thicknesses hung vertically.

I couldn't help but be a little stunned.

Do these things need to be hung like this?

"To prevent deformation. If placed horizontally, these ball screws with high precision dù will deform under the action of gravity...... "Zeng Yong also knows that Yun Kai rarely touches the processing of this kind of precision dù parts, and after the processing of such parts is completed, it is quite exquisite.

"The same principle as those plate parts and disc parts?" Yun Kai really feels that he has gained knowledge.

This warehouse is not like an ordinary warehouse, just put some shelves at random, and then put the processed parts on the shelves.

The shelves of these finished warehouses in the 1O1 base, the surface of the partitions on each floor is quite smooth and flat, and they are basically found quite horizontally. Soon after Yun Kai entered the base, he knew that these things were not for anything else, but to prevent the subtle effects of the combined force of gravity and the stationary force of the parts themselves on the parts due to the uneven placement of the processed parts.

These forces, in ordinary civilian products and even military machinery parts products, are basically negligible.

But for these precision machined parts with tolerances in μ counts, it is a very influential factor. Before the final finishing of any part, the natural aging, especially the process between semi-finishing and finishing, adopts the natural aging method, which requires horizontal placement in the natural environment, rather than random placement.

Only the natural aging after rough machining, and it doesn't matter if some heavy parts are placed casually.

Because of the uneven placement, the internal stress of the part will change slightly under the action of gravity, which will affect the accuracy.

Zeng Yong did not speak, but nodded.

These levels of precision parts can be said to have quite demanding requirements for the environment.

The finished product warehouse of the 1O1 base is very large, and the space of the finishing workshop next to it has to fight, the reason is that each part can only be placed separately, even if the same type of parts, can not be overlapped, because these precision parts are absolutely not allowed to be destroyed by any external force before assembly.

The role of the warehouse management personnel in this warehouse is not to handle, nor to put the processed parts on the shelves, these parts are put on the shelves by the masters themselves after the processing, and then use the tablet computer in their hands to make a mark, so that the managers directly in the office can see which process these parts are processed to, and at the same time can know the location of these parts.

When it is time to assemble or pack the goods, directly input the location of the parts, such as which row, which shelf, which layer, and other digital coordinates into the information receiving terminal of the arranged personnel.

This workshop has realized paperless office in the true sense.

In the whole of China, if there is such a production workshop, basically no one will believe it.

Moreover, the entire base is controlled by a third-generation galaxy computer with a computing degree of 100 billion times, which is definitely more reliable than people, and there will be no chaos.

Yun Kai took the terminal in Zeng Yong's hand, and personally searched according to the tracking list above, while comparing the finished products on the shelves. The drawings of these parts are all on the terminal, and they can be clicked out, and the processing of those positions, what process dù, there are textual descriptions, which process is responsible for whom, are clear at a glance. In particular, the various progress is indicated by color, and there are words on it, so that even those who don't understand can understand it.

The task bar of the industrial machine is subdivided according to different parts, if there are parts that are not completed, they are all indicated in yellow, and the completed ones are green......

ps: Today's state is not very good, brother, please like Hulu Power.

The third is more certain, plus there is more wood, I really can't say clearly, it depends on the state......
