"Boss, this spindle, our current processing level, can't be manufactured at all......," Kang Li walked into Yunkai's office with the drawings in his hand, and said with a frown.

Such a high accuracy is basically difficult to see in China, especially the technical instructions on the drawings specifically emphasize that it is absolutely not allowed to be poor.

The maximum tolerance on this is less than O.O1mm, even the space size is, and there is no detection method at present, even if it is made, it cannot be detected. "There are several precision machining companies in the Strait Industrial Park that specialize in processing grade precision parts, have you ever asked them?" Yun Kai said with a frown.

This set of five-axis machining center, the most complex is this spindle, the processing process is actually more than 100, especially there are many small holes and some other accessories on the position, the processing is indeed very difficult.

The female engineers recruited by the whole company, Kang Li, a 26-year-old woman, have been working in this industry for four years, or in a foreign-funded precision processing factory in the Strait Industrial Park.

Yun Kai himself appointed her as the head of the mechanical technology department.

"They can do most of the processes there, but they can't do the reverse blind hole on the inner hole wall in the middle, they say, if there is no accuracy requirements, or the position tolerance is within o.1mm, maybe they can process ......," Kang Li said to Yunkai.

"If you don't do these reverse blind holes inside, how much do they offer? To do this, how much is the quote? Yun Kai asked with a frown.

It is indeed very difficult to make such parts in China, and it is estimated that even Germany, which has the best machinery manufacturing technology, is very difficult to process.

Moreover, Europe, the United States and Japan have countless machining businesses in China OEM, and they will definitely not be willing to make precision parts at a price that is not attractive to them in China.

"The smallest one is quoted 220,000 yuan, the highest price is 280,000 yuan, all of which do not do return blind holes, if the tolerance we agree to let go of the position tolerance, and the processing fee for processing reverse blind holes will be more than 500,000 yuan...... "Kang Li simply felt that her milk was sour.

I don't know where my boss got the drawings, how complex and how to design, and I don't consider the difficulty of processing at all!

"Let's deal with some other drawings first, leave this one to me, I want to find a way, you have to inform others, the drawings that have been out, you must know the processing progress, don't just stay in the office and call, let me go to those outsourcing factories to keep an eye on the point, what kind of process is done one day, all make a record, I need to see the detailed processing progress!" Yun Kai said to Kang Li.

It's all some sister paper, if it's not easy to say it yourself, let Kangli, the boss of the technical department, say it.

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

"Okay!" Kang Li nodded.

Kang Li just went out, and Duan Yongqing, who was frowning, also came in with a few chapters of drawings to find Yun Kai, and the symbols of many of the electrical components on the drawings were not very standard, and he, a master who had read the drawings for more than ten years, felt that his head was extremely big, not to mention the girls under him who had just left the school gate.

"Duan Gong, is there any problem?" Yun Kai was speechless, this set of drawings has been going down for several days, these people looked at it separately, and it was only then that it was not as simple as they thought, just process some parts directly according to the drawings, and then buy some electrical components and assemble them according to the requirements.

"According to the technical requirements on this drawing, there is currently no way in the whole world to produce such a control system that can control such a multi-part linkage at the same time, and even if there is, the accuracy of that control system cannot be ......" Duan Yongqing not only asked his original colleagues, but also asked some of his classmates who were engaged in this area, and even called to ask the customer service of the world's top control system manufacturers such as Siemens and Farak.

They all thought they were joking.

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

In terms of control, unless a computer is used for online control, otherwise, it is impossible to complete such a complex operation control system by relying only on some small industrial control chips for real-time processing and control.

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

"Are there any other questions besides this?" Yun Kai sighed. This point is so hard to earn.

The real thing is simply not something that humans on Earth can do now.

"There are also motion control chips in various linear positions, as well as system assemblies, which are difficult to complete ......," Duan Yongqing said in a low voice.

I'm afraid that this young boss will fire himself because he feels incompetent.

"You can buy other things like linear motors with controlled transmissions on the market, right?"

"Yes, but it's very expensive, especially if we don't buy in large quantities......"

"If you can buy it, you can buy it first, don't care how much it is, of course, if you can talk about some prices, try to talk about it, after all, everyone's money is blown by the wind, and I will try to find a way to do the rest, if it really doesn't work, I can only discuss with the customer and modify the design plan...... Yun Kai said with a wry smile.

It seems that these problems should be solved by Star Dream Nine.

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

Otherwise, we will have to find a way to find some scientific research institutes in the country's mechanical and electronic fields, but when the time comes, these things may not be able to be saved......

Modify the design plan, Yunkai estimated that this was impossible.

Since Dream 9 gave itself such a task, and it was a task that he thought was very simple, and it was related to the next task, it was impossible for Dream 9 to agree to modify the design plan.

Moreover, Dream 9 is just an intelligent program, and it should not have independent design capabilities.

"Master, why are you here?" When Yun Kai was really about to go to aerospace, he wanted to ask the people from the Aerospace Technology Department to see if there was a way to solve this problem of spindle processing, and he actually saw Xiao Chuanyu walking into his office with a smile on his face.

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

Yun Kai was really a little stunned.

Some time ago, Xiao Chuanyu was still saying that aerospace is not allowed to retreat now, and they still have the idea of rehiring him in the workshop, so they are actually ready to come here at this time?

Here's what's going on.

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

"Rules are dead, people are alive, but your master and I have been in the aerospace industry for forty or fifty years, can't I think of such a way?" Xiao Chuanyu said with a smug smile, "Since I promised you last time, although I did not agree in the workshop at that time, I went directly to the company leaders, and they agreed that I would rest at home, but if there is something that can't be done in the workshop, I still have to go back, and I will take the salary, hehe......"

"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 technology of Aerospace, followed me when he was interning in the workshop, but he followed me for a few years, didn't he help with such a little thing?" Xiao Chuanyu said proudly to Yun Kai.

Those technical masters of aerospace, who doesn't have a little relationship with it?

"That's a good feeling, I'm having a headache at this moment, there is a part here that has found a lot of precision machining companies, and I can't do it, I'm going to find someone from the Aerospace Technology Department to help build a little bit......" Yun Kai didn't expect that Xiao Chuanyu still had such a relationship in aerospace.

As he spoke, he handed the drawings to Xiao Chuanyu.

Although aerospace has a large number of precision machining business, those precision machining parts are still made by themselves.

Their high-end processing capacity is mainly used for the processing of the core parts of the rocket engine and some other high-precision parts of weapons and equipment, and ordinary precision machining workshops can't do those jobs at all.

Of course, such a precision machining workshop is not in the Economic Development Zone now, but still remains in the base in the depths of Daba Mountain.

The workshop is equipped with the best precision equipment that China can get, and at the same time, it is also equipped with the best skilled workers in China, as well as process engineers and programmers......

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

Yun Kai once wanted to enter that workshop, but unfortunately, his skills were not up to par, and he was not even enough to get started. Moreover, if you want to enter that workshop this year, you must work in the precision workshop of Aerospace in Rongcheng for 20 years!

In this workshop, Yun Kai only heard a few of his masters say it.

It is impossible to imagine what kind of precision parts are produced in it, and people who have not worked in it, or who have never seen parts of that precision level, are simply unimaginable.

Yunkai wants to go to that workshop, because the people in that workshop not only have high salaries and good treatment, but most importantly, if they work for half a year, they will have half a year's vacation!

Because of the processing of those precision parts, many key processes are basically manual, senior technical workers are often highly concentrated when doing this, and all workers basically only work for six hours a day
