Super manufacturing empire

Zeng Yong's words immediately made Yun Kai dumbfounded. After reading this drawing, he just thought about the general processing technology, and finally did not consider the final assembly.

Outside mechanical processing plants are generally only responsible for mechanical processing, and such super high-precision parts will not be assembled in these plants outside.This is related to the key assembly technology and assembly process, which is a technology with a high level of confidentiality.

This is also something that reflects the core competitiveness of an enterprise, and no enterprise is willing to share it with others.

The processing of individual parts and the processing of a complete set of equipment are two different things. The processing cost of a complete set of parts is much higher than that of individual parts, especially some high-precision equipment parts.

"Zeng Gong, I also know this situation, but you also know the technical situation outside compared to you. Such high-precision parts not only do not have the kind of ultra-precision machining parts, but also do not have that kind of superb technology..." Yun Kai said to Zeng Yong with a wry smile.

"Zeng Gong, you can just tell Boy Yun if we can process it..." Sun Qianming frowned and said to Zeng Yong.

This is something explained above, because it is too difficult. Zeng Yong was dealt with urgently last night. He was afraid that after signing the contract, he would not be able to provide parts as required by the drawings. Then he would be embarrassed. What kind of equipment Kay produces and what to do next is probably difficult.

"Yes, Zeng Gong, can you see if this can achieve the design accuracy on the drawing..." Yun Kai also said expectantly.He even has a hunch that these two spindles may even account for a very large proportion of the production cost of the entire product.

Zeng Yong saw both Sun Qianming and She Hongwen winking at him, and told him at the beginning that he had to give this to the next step anyway. This was the task arranged by the above.However, he still has no bottom in his heart: "Boss Yun, there is definitely no problem when this product is made, but 100% of the design accuracy requirements are met. I can't guarantee or guarantee..."

"If the tolerance is increased by 20%?" I heard Zeng Yong say this.Yun Kai couldn't help feeling anxious.

If the accuracy cannot be guaranteed, what use is there to do it?

"Fifty percent?" Seeing Zeng Yong shaking his head, Yun Kai suddenly felt pain.This job is indeed a painful thing, and the processing precision is high, so it is not to mention it, but the assembly gap.The production reserves are actually higher than the micron level. If the Dabashan base cannot do it, where can he find a company that can produce it?

Siemens Machinery Laboratory in Germany?

American General Machinery Laboratory?

Alstom Machinery Laboratory in France?

It's impossible!They do it every year with a large number of precision processing companies specializing in processing foreign trade parts in China.

The foreign-funded machinery processing plants in the Cross-Strait Industrial Park in Chengdu that can perform super-precision processing are basically helping their laboratories to produce some super-precision parts.

They simply don't have much time to engage in their non-profitable outsourcing processing.

"Boss Yun, you are also engaged in machinery. It should be understood that even if the tolerance is doubled, the gap will only be expanded to one μ. The material of 30crmnsia is not a special material. There will be a temperature difference in the range of normal temperature. The slight deformation, we have to have a temperature difference of more than ten or twenty degrees at least a day, and even a temperature change of more than forty degrees a year. Even if this part is processed and assembled, there is no change in your hand. The way to ensure accuracy is always in our workshop..." Zeng Yong's explanation was very detailed and reasonable, causing Yun Kai and the other two big men to frown.

But Liu Hu's ears, who began to perform bodyguard duties as soon as he entered the office, were even more confused.Zeng Yong said so much, he didn't understand at all, but he still felt a sense of unclearness.

These are all things that go up to the top, you have to learn it, and you can use it to fool people in the future.It is absolutely possible to bluff people who are knowledgeable but not very proficient. As for those who don't understand Xiaobai, it is even more so.

Several people can know that even rising and falling temperatures can affect steel deformation.But if these guys can explain what a μ is, it would be better.

So, even though I didn't understand at all, I felt that this high-end, high-end Liu Hu stood upright on the side, listening carefully, and remembering hard to avoid losing the boss's face.

"Indeed, I didn't think about this problem at the beginning. Mr. Zeng, if we conduct final inspections in your production workshop, and then we don't consider the deformation, and the tolerance range is not increased, can it be processed?"

"This can't be guaranteed..." Zeng Yong said, but Sun Qianming wanted to beat him up.

"How sure can you be sure that the processing will be successful?" Yunkai also knows. It seems that this matter really takes time to ask Xingmeng No. 9 whether the tolerance range can be enlarged, otherwise, there is really no way to do this job. .

"If the tolerance range can be increased by 20%, you can be sure of 60%..." Zeng Yong closed his eyes and silently thought for a while, then raised his head and said to Yun Kai.

"That's OK, let's sign the contract according to this technical standard, and make a note in the contract..." All mechanical engineers know that in the design process of all mechanical equipment, design engineers will improve the design accuracy more likely, just for Achieve the assembly accuracy they really want.

In other words, the design drawings are likely to be one or two levels higher than the actual accuracy required.

However, this set of drawings was thrown out by Xingmeng 9, and Yunkai really couldn't guarantee whether there was a design reserve.

This spindle needs to reach the highest speed in the future, but 300,000 revolutions!Even if it is used at 80% of the load, there will be 240,000 revolutions per minute. Don’t look at 20%, only 0.1μ, and 1% of the hair. But what is the final performance? No one can tell the impact.

"All right... Cloud boss, although I know some things shouldn't be asked. But can you tell me what equipment this spindle is used on? I'm really curious, how accurate this whole set of equipment must be!" Zeng Yong sighed helplessly and agreed with Yun Kai's opinion.

Even if he racked his brains, he couldn't figure out what kind of equipment's main shaft could use such high precision.According to his knowledge, this kind of precision spindle is more than one level or two higher than any equipment currently known in the world. According to the existing technical conditions, the tolerance design standard of this spindle.Basically it has reached the standard of it0 or even it01 (in the "National Standards for Tolerance and Coordination gb1800~1804-79", it is used to represent the standard tolerance, and the grades are it01, it0, it1~it18 and a total of 20 grades, of which it18 has a precision The lowest grade. Basically not adopted. In the machinery industry, the lowest precision grade is the blank cast in the first process or the material cut by fire wire is this grade, and it is above 4, basically this precision grade is in the entire world There are very few inside...In the words of Master Calabash, it4 level can also be achieved by means of confidential grinding or super processing, the accuracy level above that. Basically it is in the category of non-human processing!)

Even in some specific cases, it can be regarded as having reached the highest accuracy level of relatively zero!

The bus base is a secret scientific research and manufacturing base with the highest level of China’s military. The highest precision level produced is only IT3 level. Most of the parts tolerance level is IT4 level, and other precision levels below IT5 level can be achieved with equipment. There is no need for them to produce at Dabashan base.

The most important thing is that, except for some of the world's top production equipment that can process parts with accuracy of it4 level, parts above this level must be achieved manually by experienced technicians!

and so.He couldn't help but wonder which planet Yunkai got his business from.

"Well, I'll just say it straight. Anyway, you are all people who can keep secrets, although at the beginning I said this was the key precision spindle of the five-axis machining center. At that time, because I didn't know it, it was a Once the main shaft of an industrial master machine is assembled, it can process parts that can only be produced by hand, such as level 1 to level 3. Of course, this is theoretically..." Yun Kai said mysteriously.

Now I am short of money. Dabashan base is the concentration camp with the most top equipment in China!They don't have such top-level equipment in there. If there is such a device, their production efficiency can at least provide hundreds of times!

"By the way, that set of roller screws is okay, right?" Yun Kai saw that Sun Qianming, She Hongwen and Zeng Yong's eyes were glimmering, and he knew what they were thinking, and hurriedly changed the subject.

He has successfully aroused their curiosity.

Once they confirm that this equipment can really achieve such processing accuracy, they will buy it no matter what the price is.

In this world, there is absolutely no equipment with higher accuracy than this one.

And the reason Yunkai wanted to do this was because he had all the hope, and Xiao Chuanyu, an infinitely trusted assembly master, told him that this level of equipment, even with auxiliary tools, can only be assembled in the base of Daba Mountain!

Yunkai wants to use the bus to get on the base to help him produce. It is impossible to just spend money.China's mid-to-super high-end equipment, many super-precision parts are assembled there, and there is no excess capacity to do the business of his small private boss.

Of course, if some equipment they want to buy can't be processed by them, this is hard to say...

ps: Thank you doni for the two monthly tickets, and thank you *t-90* and abclong for the two monthly tickets.

Brothers, if you want to add more Hulu, you don’t need to vote for the change, just like it. Now the praise rate is 0.86%. Hulu said, Hulu burst is cheaper than any author at the beginning. , Hulu does not ask for reminders, no rewards, the monthly ticket is also a great god, and Hulu wants to like it.Although, Hulu is also wanted for rewards, but I know that many readers are ordinary users. The price is much higher than that of VIP members. Hulu does not ask for rewards, just likes.In addition, the brothers of ordinary members, first upgrade to membership, so that it can be a lot cheaper, and can give Hulu more support, thank you!

Hulu also knows that it is difficult to like it. It is probably harder than Wang Feng's headline. But Hulu sincerely hopes that all the brothers will like it, so that Hulu will have motivation.

A thumbs up is only two cents. In this era, a god horse can't do it, but it can make the gourd give up everything and do it hard!

come on!

Give the gourd power!
