Super manufacturing empire

"Boss, this spindle can't be manufactured at our current level of processing..." Kang Li walked into Yunkai's office with the blueprint in her hand, frowning.

Such high accuracy is basically difficult to see in China, especially the technical description on the drawing specifically emphasizes that it is absolutely not allowed to exceed the tolerance.

The maximum tolerance on the above is actually less than 0.01mm, even the space size is, currently there is no detection method, even if it is made, it cannot be detected.

"There are several precision machining companies in the Straits Industrial Park that specialize in super-precision parts. Have you ever asked about them?" Yun Kai frowned.

This set of five-axis machining center, the most complicated is the main shaft, the machining process actually exceeds a hundred, especially there are many small holes on it and the location of some other accessories, the machining is really very difficult.

The female engineers recruited by the entire company are also the 26-year-old woman Kang Li who has worked in this industry for four years. They are still in the super precision processing factory opened by foreign capital in the Straits Industrial Park. I don’t know why. But I went to the Xingmeng company to apply.

Yunkai himself appointed her as the head of the mechanical technology department.

"They can do most of the processes, but they can't do anything about the reverse blind hole on the inner wall of the middle hole. They said that if there is no accuracy requirement, or the position tolerance is within 0.1mm, it may be able to process... …" Kang Li said to Yun Kai.

"If you don't do these reverse blind holes, how much do they offer? How much do they offer?" Yun Kai frowned and asked.

Such parts are indeed very difficult to make in China. It is estimated that even Germany, which has the best mechanical manufacturing technology, is very difficult to process.

Moreover, there are countless machining operations in Europe, America and Japan that are placed in China for foundry. They will certainly not be willing to make super-precision parts that are not attractive to them at such a price in China.

"The lowest price is 220,000 yuan, and the highest price is 280,000 yuan. They don’t make return blind holes. If the tolerance is agreed, the processing fee for reverse blind holes is 500,000 yuan. Above..." Kang Li felt her milk was sour.

I don’t know where my boss got the drawings, how complicated and how to design, so I don’t even consider the difficulty of processing!

"Handle some of the other drawings first. Leave this to me. I will find a way. You have to inform others about the drawings that have been sent. You must know the progress of the processing. Don’t just stay in the office and call me. Those outsourcing factories stare at them, and keep a record of what level and level each day. I need to see the detailed processing progress!" Yun Kai said to Kang Li.

It's all some sister papers. If you can't say anything, let Kang Li, the boss of the technical department.

To work for your boss, you must have the consciousness to be a bad person in order to make the boss a good person.

"Okay!" Kang Li nodded.

Kang Li just went out, and the frowning Duan Yongqing also came in to find Yunkai with a few chapters of the drawings. Many of the symbols on the electrical components on the drawings are not very standard. He has read the drawings for more than ten years. The masters all felt that their heads were so big, not to mention the girls who had just left school.

"Duan Gong, is there any problem?" Yun Kai was speechless. This set of drawings had been distributed for several days. These people looked at it separately and realized that it was not as simple as they thought. They processed some parts directly according to the drawings. Then buy some electrical components as required and assemble them.

"According to the technical requirements on this drawing, there is currently no way in the entire world to produce such a control system that can simultaneously control such multi-part linkage. Even if there is, the control accuracy cannot be achieved..." Duan Yongqing not only asked the original Colleagues also asked some of my classmates who are engaged in this field, and even called specifically to ask the customer service of top global control system manufacturers such as Siemens and Farrak.

All think they are joking.

At present, the machining center produced by any company is a rotating high-speed rotating spindle with only one main motion, and this set of drawings in Yunkai's hand actually has two power cutting spindle heads that need to be involved at the same time!

In terms of control, unless a supercomputer is used for online control, otherwise, a numerical control system that only relies on some small industrial control chips for real-time processing and control cannot complete such complex arithmetic control at all.

This set of equipment is no longer in the category of a conventional five-axis machining center, and can even be regarded as a nine-axis nine-link machining center!

"Apart from this, are there any other questions?" Yun Kai sighed.This point is too hard to earn.

Real stuff is simply not something that humans on earth can do now.

"There is also the motion control chip in each linear position and the system assembly. The above design is difficult to complete..." Duan Yongqing lowered his head and said in a low voice.

I was afraid that the young boss would fire himself because he felt he was incompetent.

"You can buy other things like linear motors that control the transmission in the market, right?"

"Yes, but the price is very expensive, especially when we buy in small quantities..."

"If you can buy it, just buy it first. Don't worry about the amount of money. Of course, if you can talk about some prices, try to talk as much as possible. After all, whose money comes from the wind, I will try my best to find other ways. If it is not possible, I can only discuss with the client and modify the design plan..." Yun Kai said with a wry smile.

It seems that these problems should be solved by Xingmeng Nine.

Isn't he an auxiliary system? These are things they can't handle at the moment, and they must find his auxiliary system to help.

Otherwise, I have to find a way to find some scientific research institutes in the country in the field of machinery and electronics, but then, these things may not be able to keep...

Revising the design plan, Yunkai estimates this is impossible.

Since Xingmeng Nine gave himself such a task, and it was still a very simple task he thought, and it was related to the next task, Xingmeng Nine could not agree to modify the design plan.

Moreover, Xingmeng 9 is nothing more than an intelligent program and should not have independent design capabilities.

"Master, why are you here?" When Yunkai was really about to go to aerospace, he wanted to ask someone from the Aerospace Technology Department through Chen Shengli to see if there was any way to solve the problem of spindle machining. He actually saw Xiao Chuanyu smile on his face. Walked into his office.

"Why, not welcome? I'm here to work here to beg you for food!" Xiao Chuanyu said with a smile on his face.

Yun Kai was really taken aback.

Some time ago, Xiao Chuanyu still said that aerospace is not allowed to retreat, and their workshop still has the idea of ​​re-hiring him. Are you actually planning to come here?

What's happening here.

"Welcome, I can't ask for it! Isn't it impossible for the aerospace side to retreat?"

"The rules are dead, and people are alive. Anyway, your master, I have been in aerospace for forty to fifty years. I can't think of such a way?" Xiao Chuanyu said with a smug smile, "Since I promised you last time, although At that time, the workshop did not agree. Later, I went directly to the company leaders and they agreed that I would rest at home. However, if there is something that I can’t figure out in the workshop, I still have to go back and get my salary, huh..."

"Such a good thing? Master, do you have a relationship with your boss?" Yun Kai was stunned. He really didn't expect Xiao Chuanyu to leave the relationship.

"Sun Qianming, the current vice president of aerospace technology, followed me when he was doing internships in the workshop. Anyway, he has been with me for a few years. Isn't it helpful for such a thing?" Xiao Chuanyu said to Yun Kai triumphantly.

Those masters of aerospace technology, who has nothing to do with them?

"Then the relationship is good, I am having a headache right now. There is a precision machining company that has found a lot of parts here, but I can't figure it out. I am going to ask someone from the Aerospace Technology Department to give some advice..." Yun Kai hasn't I thought that Xiao Chuanyu still had such a relationship in aerospace.

While speaking, he handed Xiao Chuanyu the drawing.

Although the aerospace industry has a large number of precision machining operations out of the country, those super precision machining parts are still made by ourselves.

Their high-end processing capacity is mainly used for the processing of the core components of the rocket engine and the super-precision parts of some other high-precision and cutting-edge weapons and equipment, and ordinary precision processing workshops simply cannot do those tasks.

Of course, such a super-precision processing workshop is not in the economic development zone, but still remains in the base deep in Daba Mountain.

That workshop is equipped with the top super-precision equipment that China can get. At the same time, it is also equipped with the best technical workers in China, as well as process engineers and programmers...

Put it this way, the workshop in the depths of Daba Mountain represents the most cutting-edge production capacity of China's machinery manufacturing.

Once Yunkai wanted to enter that workshop, but unfortunately, his skills were not enough, and he didn't even get started.Moreover, if you want to enter that workshop this year, you must have worked in the precision workshop of Aerospace in Chengdu for 20 years!

In this workshop, Yun Kai only heard several of his masters say.

To what degree of precision parts are produced in it, it is impossible for people who have not worked in it, or who have not seen such precision parts.

Yun Kai wants to go to that workshop because the people in that workshop are not only well-paid and well-paid, but most importantly, they have half a year's vacation after working for half a year!

Because processing those super-precision parts, many key processes are basically manual. When senior technical workers are doing this, they are often highly concentrated. All workers basically only work six hours a day.
