Super manufacturing empire

Chapter 030 Super processing technology-mirror turning

"What are you looking at? Don't you all go to work?" Yun Kai just walked to the door of the office and found that the door was full of people.

Wu Feng's general manager's office is very close to the production workshop, and I don't know how much these bastards have heard.

"Master, did you leave like this?" Seeing Yun Kai coming out, other apprentices who were watching the excitement and workers who were not very close to Yun Kai broke up, leaving only Hu Cheng, Feng Wen, The three of Chen Fei.

According to the current situation, Logan Factory is finished.

Even if these jobs are not processed within the prescribed time limit, or Long Guang simply does not do it, Chen Shengli and Deng Dongquan will find a way to protect themselves.

They absolutely dare not report the matter of substitute materials, and even those who know the truth will think of ways to seal it up.Otherwise, their malfeasance and oversight will prevent them from getting good fruits.

In particular, there are several military representatives in the Hongqi Machinery Factory. Once they learn about the situation, they will report it 100%.

The military representatives stationed at the Hongqi Machinery Factory basically change one batch of products. It is very difficult to make them turn one eye and close the other.

In the case of a group, they would not go to buy military representatives, and it would be uneconomical to do such a thing.

I just cultivated the feelings and tacit understanding. This batch of products has been finished, and they have been transferred. Next time I will work on a different product, and I will be another military representative...

Instead of buying these military representatives, it is better to have a good relationship with the inspection of finished products. They cannot control the production schedule of the products, but they have the final say when the products are qualified.On the quality tracking card of any product, as long as the final product inspection is not stamped and signed, even the general manager of the group company has no right to say whether the product is qualified or not.

"What can I do if I don't leave? Nobody can have a special face like being used as a butt?" Yun Kai was very angry. Can he give up the job? Now he doesn't care about anything.

I was forced to leave by Li Shufen at first, and then Wu Feng knelt and came back by himself; now at the beginning, I just negotiated with Yang Wei to produce the more urgent products first, and this happened. Li Shufen once again let Get out.

No one can stay any longer.

I came back on my own, not on my own initiative.

And now it seems that who the Longguang Factory is, he, an old employee who has been working for three years, can't figure it out...

"Master, you are gone, what shall we do?" Feng Wen looked like he wanted to leave with Yun Kai.

"Master, where are you going, take us..." Hu Cheng wanted to follow Yun Kai the most. He believed that he could only learn something by his side.

"You stay in the Longguang factory now and look at the situation. If the two of them don't care about the factory's production, call me! If Yang Wei comes to manage the factory, you guys call me too, master me If you don't have any other skills, it's no problem to get you a job." After Yun Kai finished speaking, he left the Longguang factory.

Long Guangchang had nothing to do with him after Li Shufen's words that made him get out.

The friendship with Wu Feng has come to an end.

The three years I spent in the Longguang Factory had been enough to offset the kindness that Wu Feng had lent him 6,000 yuan back then.This time I came back, still to repay the favors Wu Feng signed by borrowing money back then.

Yun Kai had never inquired about what happened between the two men, and he was too lazy to inquire.

He is the kind of personality that has nothing to do with himself and hangs up high.

Especially, his own porridge is not cold at the moment, and he can no longer care about helping Wu Feng blow the glutinous rice balls in his bowl.

The most urgent task now is to find a way to process the old Maozi's heavy thin-walled parts within three months, so as to save his life.

At present, my own affairs have not been implemented, and there is no way to give a clear answer to the apprentices who want to follow me.

"Hey, Huang Kui, what's going on? Nima, I haven't called me at the moment. You guys have not been patronizing sisters, and forgot about this matter to the country of Java?" Yun Kai As soon as he left the Longguang factory, he dialed Huang Kui's number.

"Brother, can you not urge me like this? From last night to now, my sister-in-law has made several calls..." Huang Kina's murmured voice came from the receiver, and it seemed that he was harassed by Zhao Ling. .

"Stop talking nonsense, I want the result now. If I can't provide it, I will find someone else to go. Don't tell me that I can't do it authentically..." Yun Kai stunned for a moment before he understood what Huang Kui said. The sister-in-law is Zhao Ling.

"When I do errands, you can rest assured. There is inventory in the factory in Tianshui, but they are all ordered by customers. I am trying to find a way to cut it down for you. I will give you an answer tonight. As for the fine processing of large pure tungsten parts. None of them knows about the knife..."

"Well, I'll call you tonight. As for the props, I will figure out a solution myself..." Yun Kai sighed.

If the equipment is fixed, the tool problem cannot be solved, and the finishing is also troublesome.

Especially the roughness of the inner surface of this gadget is required to be 0.8, and the lathe is for finishing, and then only the cubic boron nitride and diamond tools can be tried.

Both of these tools are tools that can be mirrored. Relatively speaking, diamond tools are harder and more wear-resistant than cubic boron nitride turning tools.

However, it is impossible for Yunkai to imagine how difficult it is to perform mirror turning on super-hard materials such as pure tungsten on ordinary heavy domestic equipment.He had heard from the lathe master once that there was a master in the military industry system who was able to use ordinary lathes for mirror turning. However, in order to keep the eyes of the aerospace group on the top of the head, the tail was raised to the sky. The technicians gained insights, and spent tens of thousands of dollars to invite the master. As a result, the master wandered for a full circle in the Aerospace XIV Group and did not find satisfactory equipment. Finally, in desperation, He chose an ordinary 6140 that he thought was in the best condition, and debugged the equipment for seven days, but in the end, it still failed to turn the mirror.

Since then, the old master has retired directly...

Since then, no major has ever come to Chengdu Aerospace XIV Group to perform this kind of super processing.

Yun Kai doesn't think he can accomplish the kind of ability that the master can't do.

According to Guo Guichuan, a master lathe, if you want to complete such super-difficult processing, you must reach the realm of man-machine integration.

He didn't even know what state it was.

At least, while repairing the equipment, although he was able to find out most of the equipment failures, he was absolutely unable to find the fault like those top masters. Once the equipment is running, it can be found by listening or watching directly.

The so-called mirror turning processing refers to the super precision processing with the surface roughness value of ra0.01μm or less after the turning processing.This kind of super-precision machining has very strict requirements for the three elements of cutting-the back-cutting amount ap must be less than 0.01mm, the feed rate f=0.02~0.04mm/r, and the cutting speed vc=56.5~226m/min.

Moreover, during the processing, the operation of the equipment must be stable. This processing requires both the spindle and the guide rail to be supported by hydrostatic or aerostatic pressure.At the same time, the axis rotation accuracy of the main shaft of the lathe must be greater than 0.01μm during the rotation, and no jitter or vibration is allowed during the operation.

And this kind of vibration or shaking, not only can not be sensed by people or the most sensitive animals, but even by many sophisticated devices!This kind of equipment, currently only Switzerland and Germany have such production technology in the world, and even Japan and the United States cannot produce such super precision equipment!

Such super processing technology not only has strict requirements on the operation technology of workers, but also has strict requirements on equipment, environment, and turning tools.

Riding on his tattered bicycle that he bought from the carport of the Aerospace Academy three years ago for 30 yuan, Yun Kai went directly to the training factory of the Aerospace Academy.

"Are you not going to work?" Seeing Yun Kai rush to his side so early, the master looked surprised.

"Being fired...Master, do you have any good suggestions for that craft?" Yun Kai smiled, not the slightest embarrassment about being fired again, as if saying something else.

"Then do it by yourself. I discussed with Master Xiao and the others. It is impossible to achieve this accuracy directly with lathe processing, mainly because of the surface roughness, which is simply not achieved..." Master sighed Take a breath.

This job can be regarded as a super hard bone job. If you want to eat meat, you don’t have a good mouth, no!

"What if we use mirror processing in the final finishing?" Yun Kai was a little bit unwilling to give up on this.

Maybe the master is now able to complete such super-difficult processing, is it not clear?

"Baby, are you still thinking about this? When you graduated, I didn't tell you that, this is only in the legend? Foreign countries can reach it because they have ultra-precision processing equipment! Our country thinks You can't buy the kind..." Guo Guichuan really regrets it now. He wanted to tell Yunkai about this super processing technology that only exists in theory in China.

"Isn't anyone able to do it back then!" Yun Kai was a little unconvinced.

"That was the blind cat and the dead mouse! Didn't he still lose Maicheng in the end?"

"Master, is this kind of scheme really bad?" Yun Kai always felt that he should give it a try.

"No. Even if you try machining, it will be a waste of time. This kind of machining has harsh requirements for the environment. It must be processed in a constant temperature dust-free workshop. The powder produced by cutting is not removed in time or the dust in the air will be scratched. It hurts the surface of the processed parts!" Guo Guichuan knows that such a technology requires operators to be far less demanding than the precision of equipment!

Foreign countries are reluctant to sell even small precision vehicles and ships to China, let alone such heavy ultra-precision processing equipment!
