Intelligent Industrial Empire

Seeing the eager gaze from everyone on his body, Yun Fei was triumphant.

Regardless of your decades of research, theory, and research, I, a person who graduated from a bachelor’s degree, certainly can’t compare with you, but in terms of knowledge, especially in the machine tool industry, it is estimated that the entire world will be in this era. Inside, there will not be a few more long-term than their own insights.

I want you to do it now, but it’s for you to first get the fourth axis controlled by this simple PMC drive module, and use this simple four-axis machining center to produce some small parts and accumulate some fourth axis. The experience in design and control, in order to formally enter the CNC machining center equipment production in the future to reserve some technology and experience, but not for you to build a house.

Just kidding, even a three-axis machining center can't be produced. You still want to build a turning-milling composite machining center that is more difficult than a five-axis machining center?Doesn't this have to go against the sky?Yun Fei thought so proudly.

When the eyes of other people looking at him began to become sour and astringent, Yun Fei scanned everyone's faces before coughing, cleared his throat, and said to them.

"Everyone thinks that these ordinary small lathes produced by the company now can be called heavy equipment? Since the company is called Jiuyi Heavy Industry, it will definitely produce heavy cutting machine tools in the future. Therefore, the production experience of these large rotary tables must be From now on, we will carry out technical reserves." Yun Fei’s words made Sun Lin and Situ Heyun regain the urge to beat people, and also made other guys who were at least one round older than him regain those who wanted to eat meat. Look.

This kid, regardless of his young age, is too appetizing.

"Xiao Yunna, although such a rotary table will be more useful to you in the future, the scope of domestic use of heavy machinery is too narrow..." Sun Lin looked worried.

Yun Fei has become a businessman now, and all of them are profitable.

If Yunfei has invested a huge amount of money in this project in the future, he will not be rewarded in the market in the end, shouldn't he burn these research materials out of anger?You should know that the research materials of these aspects were clearly stated in the original contract that they could only be stored in Yunfei's company. The National Institute of Mechanical Engineering had to obtain Yunfei's consent if they wanted to borrow these materials.

Sun Lin doesn't think anyone can borrow it, otherwise Yunfei would not have strongly demanded a patent at the beginning, and then he would still request a patent right.

"Lao Sun, you don’t need to worry. Before, there were no CNC machine tools, so many things in our country can be produced without CNC machine tools. At most, the cost is higher and the efficiency is lower. You can rest assured that sooner or later, the country needs equipment There will be all of them, but it's just a matter of time..." Yun Fei was amused secretly in his heart for people like Sun Lin.

These people, all of them came up with such a large rotary table, not only because the domestic technology and materials failed to meet the standards, the most important thing is to consider from the use to the domestic military industry.

Yun Fei sneered at this.Many parts in the military industry that require a four-axis machining center cannot be processed by a simple four-axis machining center.

"Can you not worry about it? Buying a four-axis machining center from West Germany is more difficult than buying an atomic bomb. Finally, someone else sells it, and the price is still high. It's close to two million US dollars. We need at least hundreds of units in the country. How much does it cost? How much is the national tax for a year?" For Yun Fei, Sun Lin narrowed his mouth and said lonely.

Saying he is worried about the country and the people, that's over.The reason why he did this is because of the many high-precision equipment designed in the Institute of Machinery, and those high-precision parts can only be made with a four-axis machining center or even a five-axis machining center.Without equipment, their design cannot be verified.

Especially for many key components used in the military industry, the requirements for various geometric tolerances of the parts are quite high.There is no way to guarantee that parts are repeatedly clamped during the processing. Even if there are guarantees, they have to be scrapped to have one or two that can barely meet the requirements.Moreover, there are many unreasonable parts in the parts used in the experiment, especially after the problem is found, if the design requirements are to be fully met, the requirements for the processing of the parts will become higher.

Although the country has imported three four-axis machining centers from West Germany, those four-axis machining centers are currently the only three four-axis machining centers in China.All three were separated by aerospace, one for the aircraft manufacturing system, and the remaining one was finally taken away by the navy.

Although the Academy of Sciences is the core of the entire domestic technology, there is no way to compete with those systems that urgently need the most top-level machining equipment that China can obtain to improve the level of equipment.

"Elder Sun, even if you can produce such a fourth axis, there is no way to process those products with particularly high precision requirements." Yun Fei said to Sun Lin seriously.

The China of his world, because the three-axis machining center is shifted to the simple fourth axis in the research direction of the four-axis machining center, the research on the five-axis machining center has been stagnant.

"Xiaoyun, you said, if you machine a 12-ton, eight-meter-long shaft with two spiral grooves of a sine function curve and a cosine function curve, the groove width accuracy is within one wire, and two closed spirals The rotation center of the groove must coincide with the center line of the entire shaft, and the error cannot exceed one thread. Finally, it is necessary to do dynamic balance to keep the speed of the entire shaft at a high speed of three thousand revolutions...Let’s enlarge this rotary table to have Is it possible to do it?" Sun Lin also knew that Yun Fei, a young man, could not answer his own questions.

This problem has plagued all mechanical engineers in China for many years.

"Eight meters long and 12 tons of shaft parts require too much torque during the machining process. This is the heavy-duty lathe such as the C61125 with a 10-meter-long guide rail and a 1-meter turning diameter that can be produced in China. For high and heavy parts, even if it is to machine the outer circle, the difficulty is not generally large. Especially if it is necessary to mill a closed spiral groove on it, such a large shaft, it is impossible to complete the processing without a few days, that is, The top of the rotary table must bear at least one ton of weight and the torque generated during the rotation. To process such heavy parts, it must be a turning and milling compound machining center above the precision level!" For such a heavy duty as Sun Lin said Parts, although Yun Fei has seen more people in this world for decades, but he really doesn't know what kind of parts such parts are used for.

In the domestic military industry, what kind of equipment can use such a heavy shaft?Even if Yun Fei racked his brains, he couldn't figure out what it was for.Knowing that even if he asked Sun Lin, he would not tell himself that they had signed a confidentiality agreement.

For the confidentiality agreement, Yunfei also signed the same year.So he knows this powerful relationship.

Hearing Yun Fei talk about the turning-milling composite machining center, everyone's eyes gleamed.It seems that this kid knows a lot.

This is the first time they have heard of the term turning-milling machining center.

"What is a turning-milling composite machining center? Why haven't we heard of it?" Sun Lin was confused about the turning-milling composite machining center that Yun Fei said.

I thought it was some advanced mechanical processing equipment researched abroad. I looked at my apprentices and grandchildren, and saw all the people with a confused expression.As long as the news of foreign advanced machine tools and equipment, these people will know in the first time.

"The so-called turning-milling composite machining center is a machine tool that not only concentrates the functions of a lathe and a milling machine. This is more high-end than a five-axis machining center." Yun Fei explained to the confused people.

Turning and milling composite machining center, this era is estimated to have just proposed a concept, China will certainly not believe in understanding these.The turning-milling compound machining center did not develop rapidly until several years after entering the 21st century.

After entering the 21st century, the aviation manufacturing industry has continued to develop rapidly. Product parts are prominently manifested in multiple varieties and small batches, complex technological processes, and extensive use of overall thin-walled structures and difficult-to-process materials. The manufacturing process generally has long manufacturing cycles, Bottlenecks such as large amount of material removal, low processing efficiency and serious processing deformation.In order to improve the processing efficiency and accuracy of complex aviation products, craftsmen have been seeking more efficient and precise processing methods.In order to improve the machining accuracy and efficiency of aerospace parts, a turning-milling composite machining center appeared.

Although the equipment that appeared at that time only processed some small parts.For the processing of heavy parts, there is no way.

However, this provides Yunfei with a possibility. If the worktable of the gantry CNC milling machine is turned into a horizontal lathe, then a heavy-duty turning-milling composite machining center will be formed.At that time, many people in Yunfei's world put forward this theory, but the required investment was too large, and it was not possible to get hundreds of millions of research funds.

On the surface, such equipment only needs to install the headstock and tailstock of the lathe on both ends of the worktable of the gantry milling machine, but it is not so easy to implement.The most important thing is that the production cost of such heavy equipment is very high. Even a gantry milling machine that can process parts with a length of ten meters is tens of millions. Such a lathe is not very expensive.

But the combined price of these two items will be several times the value of ordinary such equipment for two days, even ten times, twenty times!
