Smart Industrial Empire

Seeing the earnest gazes of everyone on him, Yun Fei was elated.

Regardless of the decades of research you have done, in terms of theory and research, I, who is only a graduate of a bachelor’s degree, certainly cannot compare with you, but in terms of knowledge, especially the knowledge of the machine tool industry, it is estimated that in this era, the entire world Among them, there will not be a few who have more long-term insights than their own.

What I want you to do now is just to let you get out the fourth axis under the control of this simple pmc drive module, use this simple four-axis machining center to produce some small parts products, and accumulate some fourth axis The experience in design and control is to reserve some technology and experience in order to formally enter the production of CNC machining center equipment in the future, not for you to build a house in Gao Ling.

Just kidding, there is no way to produce a three-axis machining center, and you still want to make a turn-milling machining center that is more difficult than a five-axis machining center?Wouldn't this be against the sky?Yun Fei thought so proudly.

When the eyes of others looking at him started to become sore and astringent, Yun Feicai glanced at the faces of everyone, coughed, cleared his throat, and then spoke to them.

"Do you think that the ordinary small lathes produced by the company can be called heavy equipment? Since the company is called Jiuyi Heavy Industry, it will definitely produce heavy-duty cutting machine tools in the future. Therefore, the production experience of these large rotary tables must be Make technical reserves from now on." Yun Fei's words made Sun Lin and Situ Heyun take back their urge to beat up people, and also made other guys who were at least one round older than him take back their desire to eat meat eyes.

This kid, regardless of his young age, is too good at tantalizing people.

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

Yunfei is now a businessman.Businessmen are profit-seeking.

If Yunfei invests a huge amount of money in this project in the future and cannot get a return in the market in the end, won't he burn these research materials out of anger?You must know that the research materials in these areas clearly stated in the original contract that they could only be kept in Yunfei's company. If the National Machinery Research Institute wants to borrow these materials, it needs Yunfei's consent.

Sun Lin didn't think anyone could borrow it, otherwise Yun Fei wouldn't have demanded the patent right after he strongly demanded the patent at the beginning.

"Mr. Sun, you don't need to worry. There were no CNC machine tools before. Many things in our country can be produced without CNC machine tools. At most, the cost is higher and the efficiency is lower. Don't worry, sooner or later the country will need the equipment. There will always be, it's just a matter of time..." Yun Fei secretly felt amused at what people like Sun Lin were worried about.

The reason why these people came up with such a large rotary table was not only because the domestic technology and materials could not meet the standards, but most importantly, it was estimated that it was used in the domestic military industry.

Regarding this, Yun Fei scoffed.Many parts in the military industry require four-axis machining centers.It cannot be processed by a simple four-axis machining center.

"Can you not be worried? Buying a four-axis machining center from West Germany is more difficult than buying an atomic bomb. It is hard for others to sell it. The price is still high. It is close to 200 million US dollars. Do the math, our domestic At least hundreds of units are needed, how much does it cost? How much is the national tax for a year?" Regarding Yun Fei's words, Sun Lin pursed his lips and said desolately.

Said he was concerned about the country and the people.This is over.The reason why he did this is because there are a lot of high-precision equipment designed in the Mechanical Research Institute, and those high-precision parts must have a four-axis machining center or even a five-axis machining center to make them.Without equipment, their designs cannot be verified.

Especially for many key parts used in military industry, the requirements for various shape and position tolerances of parts are quite high.There is no way to guarantee the repeated clamping of parts during the processing process. Even if there are guaranteed parts, they have to be scrapped to make one or two barely meet the requirements.Moreover, the parts used in the test are unreasonable in many places, especially after the problem is found, in order to fully meet the design requirements, the requirements for the processing of the parts will become higher.

Although the country 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.One of the three was taken away by aerospace, one was taken away by the aircraft manufacturing system, and the remaining one was finally snatched 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.

"Mr. Sun, even if you can make such a fourth axis, there is no way to process those products that require extremely high precision." Yun Fei said to Sun Lin seriously.

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

"Xiaoyun, tell me, if you process a 12-ton, eight-meter-long shaft with two spiral grooves with a sine function curve and a cosine function curve, the precision of the groove width is within one thread, and the two closed spiral grooves The center of rotation of the groove must coincide with the center line of the entire shaft, and the error cannot exceed one thread. Finally, a dynamic balance must be done to keep the speed of the entire shaft at a high speed of [-] revolutions... Let's enlarge the rotary table to have Is it possible?" Sun Lin also knew that Yun Fei, a young man, would not be able to answer his own question.

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

"A shaft part with a length of eight meters and a weight of 12 tons has too much torque during processing. It is a heavy-duty lathe such as c61125 with a guide rail that is ten meters long and a diameter of one meter that can be produced in China. If you want to have such a machining accuracy For tall and heavy parts, even if it is to process the outer circle, the difficulty is not so great. Especially to mill the closed spiral groove on it, such a large shaft, it is impossible to complete the processing within a few days, that is to say, The rotary table must bear at least one ton of torque generated during the rotation process. To process such heavy parts, it must be a turning-milling compound machining center above the precision level!" Parts, although Yun Fei has decades more knowledge than people in this world, but he really doesn't know what kind of things 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 non-disclosure agreement.

As for the non-disclosure agreement, Yunfei also signed it back then.So he knows this powerful relationship.

When Yun Fei mentioned the turning and milling machining center, everyone's eyes lit up.From the looks of it, this kid knows a lot.

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

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

Thinking that it was some advanced mechanical processing equipment researched abroad, he looked at his disciples and grandchildren, and all the people he saw looked confused.As long as there is news about foreign advanced machine tools and equipment, these people will know it as soon as possible.

"The so-called turning-milling machining center is a machine tool that not only integrates 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 crowd.

The turning-milling compound machining center is estimated to have just proposed a concept in this era, and China will certainly not believe that it understands these.The turn-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. The product parts are characterized by multiple varieties and small batches, complex process processes, and the overall thin-walled structure and difficult-to-machine materials are widely used. Long manufacturing cycles and material removal are common in the manufacturing process. Bottlenecks such as large quantity, low processing efficiency and serious processing deformation.In order to improve the processing efficiency and processing accuracy of aviation complex products, craftsmen have been seeking more efficient and precise processing methods.In order to improve the machining accuracy and efficiency of aviation parts, the turning and milling compound 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 a possibility for Yunfei. If the workbench of the gantry CNC milling machine is turned into a horizontal lathe, then a heavy-duty turning-milling compound machining center will be formed.In Yunfei's world at that time, many people also proposed this kind of theory, but the investment required was too large, and it was simply not something that hundreds of millions of research funds could come up with.

On the surface, this kind of equipment only needs to install the two ends of the worktable of the gantry milling machine on the headstock and tailstock of the lathe, 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 ten-meter-long parts costs tens of millions. Such a lathe is not very expensive.

But the combined price of these two things will be several times, even ten times, twenty times the value of ordinary such equipment for two days! (To be continued..)
