Smart Industrial Empire

"In the past few days, I have thought about it carefully. There is no major deviation from our original strategy. Therefore, in terms of CNC lathes, we have to continue to develop, not only to develop, but also to produce the best. What is the best? A lathe with three gears of high, middle and low, and infinitely variable speed within the gear is not the best. We must produce CNC lathes capable of infinitely variable speed. Only in this way can we reproduce in the chaotic CNC machine tool market Stand firm!"

After Yun Fei finished speaking, he slammed his hand heavily on the conference table.

All the people present at the meeting showed embarrassment when they heard Yun Fei's words.Especially Savavsky, the person in charge of the technical department, was even more distressed.

The simple CNC lathe is easy to do, as long as the ball screw is used to replace the ordinary screw and the polished rod, and then replace it with a special high-precision tooth plate connected tool holder, install the CNC system, a simple CNC lathe The lathe is done.

However, it is not such a simple problem for a CNC lathe with infinitely variable speed within the third gear and a full range of continuously variable speed.Except that the machine bed can barely retain the bed structure of an ordinary lathe, all the gears in the entire headstock have to be replaced.This is not only something that can be done by changing gears, but also has various technical conditions and technical reserves.Otherwise, the Soviet Union would not have produced high-precision CNC lathes for so many years, and could only produce the lowest-level simple CNC lathes.

"Not only should we increase the research on high-precision CNC lathes, but we must speed up the research on CNC milling machines and even machining centers. We must launch our products within half a year, otherwise, with the CNC lathes produced by our company now , can only fall into a protracted price war with other CNC machine tool manufacturers. They have the country's financial blood transfusion, but we don't. If there is no way to launch high-precision CNC machine tools within half a year, our Jiuyi Heavy Industry will only face bankruptcy Or the road of being acquired is the way to go.”

Yun Fei said the last.Incomparably lost.The current Jiuyi Heavy Industry is not only his entire net worth, but also carries all his dreams.In order to produce high-precision multi-axis linkage CNC machine tools in China, it is necessary to accumulate experience from the lowest-level two-axis linkage CNC lathes and entry-level three-axis linkage CNC milling machines, and develop step by step.

As long as a CNC milling machine with three-axis linkage is produced, it becomes a machining center just to install a tool magazine that can automatically change tools on the CNC milling machine.Although it is very difficult for other CNC machine tool manufacturers in China to just install a tool magazine, it is not so difficult for Yunfei from later generations.

"What, old Sa. What's the problem?" Seeing that Sawawski's eyebrows on both sides were about to twitch together, Yun Fei asked him with a gloomy face.

"Boss, I think our CNC milling machine can't be produced within half a year..." Through the translation, Savawski also knew the difficulties the company was facing now.

The CNC milling machine, since they first came to Rongcheng, they have already started theoretical research and design in the hotel, but until now, there is no way to solve the precision control of the most basic z-axis movement of the machining center.

Anyone who knows about CNC milling machines or machining centers knows it.The most critical technology of CNC milling machine is on the z-axis that can move up and down.The positioning accuracy is controlled by the numerical control system and the ball screw.

For ordinary milling machines, except for the rotation function of the spindle, all axes move on the table.But CNC milling machines can't do that.For high-precision CNC machine tools, especially during fast positioning, the workbench itself weighs more than one ton, if several hundred kilograms of parts are added.Or do not add parts, even if it moves quickly like this, it will also cause great damage to the ball screw of the transmission.

The advent of CNC milling machines.It is for the processing of some complex parts.But where in this world are there so many complex parts processed in large quantities?Therefore, in the use of machining centers, the powerful processing capabilities and processing efficiency of machining centers in the milling of large quantities of parts were discovered shortly after the birth of CNC milling machines.

The ball screw can be compared with the ordinary transmission screw, which is far from comparable in the tooth width of the thread, and cannot drive the table in the upper ton to move quickly in the vertical direction.

Therefore, whether it is a CNC milling machine or a machining center, it can only use the worktable to move back and forth, left and right, and the light-weight spindle to move up and down.

"Why? Didn't you come out of the Institute of Mechanical Engineering? Don't tell me, it's been a few months for you, and the design of the CNC milling machine has not yet been completed!" Yun Fei was really angry.

When I read online articles before, countless time-travelers and reborn people, in their world, all of them are doing things like calling the wind and rain, and catching up with the Premier League for a few minutes.But I didn't realize that I was in this world, and I was confident that I could do a lot. Even if I couldn't catch up with the Premier League, at least it would take 20 years for CNC machine tools to at least enable domestic machine tool manufacturers to provide Some high-end CNC machine tools.

This has only just started, and it will face the fate of bankruptcy.

God, are you kidding me?

"Boss, you originally told us that we don't need to be too anxious about the design and research of CNC milling machines, so we put all our experience into the research of CNC lathes..." Savowski's voice became smaller and smaller.

He himself felt that they were sorry for giving them hope when they were about to starve to death and giving them jobs with absolutely high salaries in the Soviet Union. Although he is far away from his homeland now, the young boss in Yunfei gave them the most The superior living conditions can completely bring the whole family to live in China.

In the research institutes of the Soviet Union, they were able to complete the design tasks assigned by their superiors under the conditions of extreme scarcity of materials.When they arrived in China, could it be that the superior life made them lose motivation?

"I have said it, but I also tell you that the CNC milling machine is related to the strategic development of the entire company for decades. Why have you come out of a professional machine tool research institution after a few months? Is the design of the mechanical part really that difficult?" Yun Fei's words became louder and louder.

When they first came here, these old men still had a sense of crisis and seldom worked seriously. It turned out that Yun Fei thought that these old men who had left their hometowns were worried that after losing their jobs, they would return to the Soviet Union and continue to suffer from the cold hungry.But they didn't expect that their seriousness would return to the state they were in the Soviet Union within a few months.

The old Soviet Union is famous for its laziness.Especially when the Cold War between the Soviet Union and the United States was gradually coming to an end, and the entire country was impoverished, the operating rate of the large and medium-sized industrial production plants and mechanical research institutes throughout the entire alliance was less than [-]%!Russia under Yeltsin's control has gradually cut off blood transfusions to major research institutes and machinery factories in non-Russian countries within the entire alliance.

In the entire meeting room, everyone felt uncomfortable. The young boss Yun Fei, under the tremendous pressure, was like a mad dog, trying to catch and bite anyone!

"I really don't understand what your achievements have been in the past few months. Most of our company's ordinary lathes have mature drawings, and you have only made some basic improvements; our company's CNC lathe testing machine, But it’s just the most low-level CNC lathe, and there’s not much improvement; can it be that you, dozens of people, have only spent such a little time in the past few months?” Yun Fei’s words basically roared to Sawavsky Said.

These words also made the heads of other departments feel ashamed.

Since the start of the company, Yunfei has a lot of things to deal with every day, and he has never intervened in the management of various departments. Perhaps this is because he is young and has no management experience in large factories.But these managers with absolutely high salaries are just muddling along.

"In short, I don't care what you do, within one month, I must see the design drawing of the CNC milling machine appearing in front of me, and all departments must cooperate with the technical department seriously, otherwise, the position will be vacated for me. Give it to those who are capable." After Yun Fei finished speaking, he left angrily.

At this moment, the only way is to go to the two old fellows, Situ Heyun and Sun Lin.

Yun Fei didn't bring these two old fellows here at the beginning, but he didn't want them to just get out the simple rotary table driven by the PMC module hung on the machining center and that's it.

You know, for that set of products, in the current Chinese mechanical processing, the largest customer is only the military factory, and there are not many four-axis machining centers used in civilian products.Yunfei knows that the CNC machine tool market is far from being comparable to a single spare parts.So Yunfei generously gave up the set of rotary tables in his hand to Zhao Xingbang's factory for production. He only charged 1 yuan for the so-called patent fee for each rotary table.

Yun Fei also knows that patent fees are nothing but nonsense in China, especially in China in the early 90s!Otherwise, after nearly 30 years of developing intellectual property rights in China, except for some top-notch items that cannot be copied in China, as long as they can make money and have a market, they can find high-quality and cheap knock-offs in China. product.

The Electronics Research Institute under Tanalia has been conducting industrial production tests of the 32-bit industrial control chip that Yunfei copied from the future market in the past few months. According to the female engineer herself, it is almost ready now. .

Now there is a problem with the CNC lathe, and it cannot achieve the goal of quickly recovering the funds that Yunfei originally envisioned, so he can only find another way.

As long as the industrialized production process design of the 32-bit industrial control chip is completed, the company's current dilemma may be solved... (to be continued...)
