Super manufacturing empire

"The middle size of the scrapped spindle sleeve has the largest deformation of 8μ, and the biggest thickness error is 0.3μ, which is too far from the technical requirements on the drawing, and there is no way to modify it..." Zeng Yong answered With Yunkai's words.

If such a problem only occurs on the outer circle of the outermost sleeve, it is not a problem at all, because the outer sleeve does not need to be rotated, but the two inner sleeves use electromagnetic principles to rotate towards each other, thereby increasing the speed to Three hundred thousand revolutions above.

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

In other words, this spindle does not actually need precision bearings!

Once there is deformation, the gap between the three sleeves with small gaps invisible to the naked eye will become uneven, which will cause collisions. When the tool is installed in the middle of the spindle to process the parts, there will be The force acts on the spindle, and the uneven magnetic field becomes more chaotic through the principle of leverage, causing the spindle to be scrapped...

"That is indeed scrapped and nothing can be saved. If there is no problem with the other inner sleeve and outer jacket, let's make up another middle sleeve material. Let's look at the scene first before talking." Yun Kai nodded.

It is not a problem to waste hundreds of thousands of processing fees. What is lacking now is time.

The original task of a hundred years must now be completed in twenty years.

The entire base stopped because of a problem with the production of this spindle.The various aircraft parts being processed in the base also stopped because of a schedule problem.Just because emotions are contagious.

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

If you are in a bad mood, you must make a mistake in your work.

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

This is basically the amount of scrap in the original month.

A few people quickly entered the base production workshop deep in the mountain. In the empty workshop, no one was seen. When they arrived at the largest finishing workshop, Yunkai discovered that they were on the bench outside the warehouse near the office. , Placed three cylindrical parts with smooth outer surfaces like mirrors.When you approach, you can see the shadow of yourself reflected on it.

The appearance is very good.

"Are these three?" Yun Kai sighed. If it were ordinary parts placed outside, they weren't the actual parts at all, and they could only be reduced to the price of those iron shavings.

"The thickness of the other two pieces is one hundred symmetrical points. Relative to the reference size, the maximum thickness exceeds 0.4μ and the minimum is 0.02μ. The largest deformation is five μ3, and the deformation exceeds too much......" Zeng Yong said to Yunkai Explained.

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

"Arrange someone and start trial processing another set immediately. At that time, the main thing is to ensure that the thickness is consistent, the allowable error does not exceed 0.25μ, and the deformation is controlled within 4μ5..." Yunkai opened the computer bag in his hand, took out the computer and pretended to be Read the three-dimensional assembly drawing and the parts drawing again.He sighed again, and directed to She Hongwen.

Such precision parts.Basically, it is no longer capable of processing in the human category, but there is no way, even if it is 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 and cutting-edge parts are filed raw with the file in their hands.

The 101 base may be the most efficient place in China. Since the boss Yun Kai has said it and agreed with the over-tolerance, given the over-tolerance range, there is no pressure at all.Of course, with such a small tolerance range, machining is not an easy task.

"Are the key parts such as the roller screw and the guide rail done?" She Hongwen went to inform people to start work, and Yun Kai was led by Zeng Yong to the warehouse.

"We produced our own products. Wang Jinshan said that the products processed by your Xingmeng Machinery have been processed. All kinds of large castings have been put into the finished product warehouse by Hongqi Machinery Factory. They will be loaded and transported to the base tonight. But this set of spindles and the finishing control system and branch motors provided by you are things that we cannot produce..."

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

"There are not many processing tasks on Xingmeng Machinery? It's not that they should be handed over to the finished product warehouse of Hongqi Machinery Factory and sent together?" Yunkai's return before the New Year meant that Xingmeng Machinery was relocated. So there was no time to ask about the production situation. Originally, I planned to ask them about the production progress when I went to KTV after the meal.

Xingmeng Robots still has 132 and many other production tasks in other factories. For these tasks, you must wait until the end of the year to collect fake Yunkai to communicate with their outsourcing officer.

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

"I don't know the specifics. I'll call Hongqi Machinery Factory in a moment. If they don't send it to Hongqi Machinery, you can only wait for you to bring them here..." Zeng Yong said to Yunkai as he walked. .

Yun Kai nodded, did not speak any more, and followed Zeng Yong directly into the warehouse.

Tracking the production progress of various parts is mainly to see to what extent the various parts are processed, so that the assembly can be arranged.

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

"Let me go, what are these ball screws for hanging up like this?" As soon as he entered the warehouse, Yun Kai saw a row of ball screws with arms of different lengths hanging vertically on a shelf in a corner of the warehouse.

Can not help being a little surprised.

Do these things need to be hung like this?

"To prevent deformation. If placed horizontally, these highly precise ball screws will deform under the action of gravity..." Zeng Yong also knows that Yunkai rarely touches the processing of such precision parts. After the processing is completed, it is quite particular.

"The same principle as those board-type parts and disc-type parts?" Yun Kai really felt that he had gained insight.

This warehouse is not like ordinary warehouses, just put some shelves on it, and then put the processed parts on the shelves.

For the shelves of these finished warehouses in the 101 base, the surface of the partitions on each layer is quite smooth and flat, and they are basically found to be fairly level.Soon after entering the base, Yunkai knew that these things were not for anything else, but to prevent the processed parts from being placed unevenly, under the action of gravity and the static force of the parts themselves. The subtle impact.

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

But for these super precision machined parts whose tolerance range is counted in μ, it is a very influential factor.Any part has to undergo natural aging before finishing the final finishing, especially the process from semi-finishing to finishing. Natural aging is required, which requires horizontal placement in the natural environment, rather than random placement. Up.

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

Just because it is not placed horizontally, under the action of gravity, the internal stress of the parts will change slightly, which will affect the accuracy.

Zeng Yong did not speak, but nodded.

These ultra-precision parts can be said to have quite harsh requirements for the environment.

The finished product warehouse of the 101 base is very large, and it can be matched with the space of the finishing workshop next to it. The reason is that each part can only be placed separately. Even the same type of parts cannot be stacked, because these are so precise. Before the heinous parts are assembled, no external force is allowed.

The role of the warehouse staff in this warehouse is not to carry or place the processed parts on the shelves. These parts are placed on the shelves by the masters after the processing is completed, and then use the tablet in their hands. The computer makes a mark so that the manager directly in the office can see which process these parts have been processed, and also know the location of these parts.

When it is time to assemble or pack and ship, you can directly input the position of the parts, such as which row, which shelf, and which layer, the information receiving terminal of the personnel arranged by the digital coordinate input.

In this workshop, a paperless office is truly realized.

In the entire 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 supercomputer with a calculation speed of 100 billion operations, which is definitely more reliable than humans, and there will be no trouble.

Yunkai took the terminal in Zeng Yong's hand, and personally searched according to the tracking list above and compared the finished products on the shelf.The drawings of these parts are all on the terminal, and they can be displayed with one click, and the processing status, to what extent, has a literal description, and who is responsible for which process is clear at a glance.In particular, the various progresses are indicated by color, and there are also texts on it, so people who don’t understand can understand it.

The task bar of the industrial mother machine is subdivided according to different components. 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 to give Hulu motivation.

The third is that there are definitely some, and there is more of it, and it is really not clear, it depends on the status...
