"In the past few days, I have thought about it seriously, and there is no major deviation in the original strategy we set, so we have to continue to engage in CNC lathes, not only to do it, but also to make the best one. What is the best? High, medium and low three gears, the lathe of infinitely variable speed in the gear, is not the best, we must produce CNC lathes that can carry out stepless variable speed, only in this way, we can reappear in a chaotic CNC machine tool market on the foothold! ”

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

When the people attending the meeting heard Yun Fei's words, their faces showed embarrassment. In particular, the head of the technical department, Savawski, had a difficult look on his face.

As long as the ball screw is used to replace the ordinary screw and the smooth rod, and then replace it with a special high-precision toothed disc connection of the tool holder, install the CNC system, and a simple CNC lathe will be completed.

However, the CNC lathe with infinitely variable speed in three gears and the full range of infinitely variable speed is not such a simple problem. In addition to the machine bed can barely retain the bed structure of ordinary lathes, 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 all aspects of technical conditions and technical reserves. Otherwise, the Soviet Union would not have failed to produce high-precision CNC lathes for so many years, and could only produce the lowest level of simple CNC lathes.

"Not only should we increase the research of high-precision CNC lathes, but we must also speed up the research of 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, we can only fall into a protracted price war with other CNC machine tool manufacturers. They have the country's financial transfusion, we don't, if there is no way to launch high-precision CNC machine tools within half a year, we Jiuyi Heavy Industry can only face bankruptcy or be acquired this way to go. ”

Yun Fei said the most reluctant. Extremely 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 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 the three-axis linkage CNC milling machine is produced, it becomes a machining center for the tool magazine that can automatically change the tool by installing a tool magazine on the CNC milling machine. Although it is only a very difficult thing to install a tool magazine for other CNC machine tool manufacturers in China, it is not so difficult for Yunfei from later generations.

"Why, old Sa. What's the problem? Yun Fei saw that Savavsky's eyebrows on both sides were about to squeeze together, and asked him with a gloomy face.

"Boss, I think our CNC milling machine can't be produced in half a year...... "Through the translation, Savavsky also knows the problems that the company is facing.

CNC milling machine, from the time they first came to Rongcheng, they have begun to work on theoretical research and design in the hotel, but until now, there is no way to solve the precision control of the Z-axis of the most basic machining center.

Anyone who knows about CNC milling machines or machining centers knows the way. The most critical technique of the CNC milling machine is on the Z-axis, which can be moved up and down. The positioning accuracy is controlled by the numerical control system and the ball screw.

In ordinary milling machines, except for the rotation function, all the shafts move on the table. But this is not the case with CNC milling machines. High-precision CNC machine tools, especially when it comes to rapid positioning, weigh more than one ton on the workbench, and add hundreds of kilograms of parts. Or without adding parts, it is such a fast movement, which will also cause great damage to the ball screw of the transmission.

The advent of CNC milling machines. It is to do some complex parts processing. But where is there so much processing of complex parts in this world? Therefore, in the use of machining centers, machining centers in the milling of large quantities of parts, strong processing capabilities and processing efficiency have been discovered soon after the birth of CNC milling machines.

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

Therefore, whether it is a CNC milling machine or a machining center, the worktable can only be moved forward and backward, left and right, and the spindle with a very light weight can be moved up and down.

"For what? Didn't you come out of a mechanical research institute? Don't tell me, you've been a few months now, and the design of the CNC milling machine has not been completed until now! Yun Fei was really angry.

When I used to read online articles, countless traversers and reborns were all calling for wind and rain in their world, catching up with the Premier League. But I didn't think that I was in this world, full of confidence that I could do a lot of work, even if I can't catch up with the United States, at least in the CNC machine tools, it took one or two decades to at least enable domestic machine tool manufacturers to provide some high-end CNC machine tools.

This is just the beginning, and it will face the fate of bankruptcy and bankruptcy.

God, are you kidding me?

"Boss, you originally told us that there is no need to be in a hurry to design and study CNC milling machines, so we put all our experience into the research of CNC lathes......" Savavsky's voice became quieter and quieter.

He himself felt sorry for the man who gave them hope when they were about to starve to death, and gave them absolutely high-paying jobs in the Soviet Union, although now far away from his homeland, with the most superior living conditions given to them by the young boss of Yunfei, he was able to bring the family to live in China.

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

"I said, but I also told you that CNC milling machine is related to the strategic development of the entire company for decades, for what has been a few months now, you are a professional machine tool research institute out, the design of the mechanical part of a CNC milling machine, is it really so difficult?" Yun Fei's words became louder and louder.

When they first came, these old Maozi were still able to have a very sense of crisis, and they rarely took their work seriously, so Yun Fei thought that these old Maozi who had left their hometown were worried that after losing their jobs, they would return to the territory of the Soviet Union and continue to suffer from cold and hunger. Unexpectedly, within a few months, their earnestness would return to the state they had in the Soviet Union.

The laziness of the old hairy man of the Soviet Union, that was famous. Especially when the Cold War between the Soviet Union and the United States gradually came to an end, and the whole country was impoverished, the operating rate of large and medium-sized industrial production plants and mechanical research institutes throughout the alliance was less than 30%! Russia, under Yeltsin's control, gradually cut off blood transfusions to the major research institutes and machine factories in the territory of non-Russian countries throughout the Union.

In the entire conference room, all the people felt uncomfortable, Yun Fei, the young boss, was like a mad dog under huge pressure, and he was basically catching and biting anyone!

"I really don't understand what your achievements are in the past few months, most of our company's ordinary lathes have mature drawings, and you have only made some basic improvements; The test machine of our company's CNC lathe is only the lowest-level CNC lathe, and there is no big improvement; Could it be that you dozens of people, these months have been so little? Yun Fei's words were basically said to Savavsky with a roar.

These words also made the leaders of other departments embarrassed.

Since the start of the company, Yun Fei has endless things to deal with every day, and he has not intervened in the management of various departments at all, perhaps because he is young and has no management experience in large factories. But these managers, who have absolutely high salaries, are also getting by.

"In short, I don't care what you do, within a month, I must see the design of the CNC milling machine appear in front of me, and all departments must seriously cooperate with the technical department, otherwise, they will make room for me and let people who have the ability to sit." After Yun Fei finished speaking, he left angrily.

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

Yun Fei brought these two old guys here, not just to let them just get out the simple rotary workbench driven by the PMC module attached to the machining center.

You must know that the set of products, in the current Chinese machining, the largest customer is only the military factory, and there are not many four-axis machining centers used in civilian products. The CNC machine tool market is far from being comparable with a single spare part. Therefore, Yun Fei generously gave the set of rotary workbenches in his hands to Zhao Xingbang's factory for production, and he only charged 10,000 yuan for the so-called patent fee for each set of rotary workbenches.

Yun Fei also knew that patent fees, in China, were just a nonsense thing, especially in China in the early nineties! Otherwise, after nearly 30 years of intellectual property rights in China, except for some of the most top-notch things that cannot be copied in China, as long as there is something that can make money and has a market, it can find high-quality and low-cost copycat products in China.

Tanalia's Electronics Research Institute, in the past few months, is engaged in the industrial production test of the 32-bit industrial control chip that Yun Fei copied from the market, according to the female engineer herself, is now about to be eyebrows.

Now there is a problem on the CNC lathe, and it is impossible to achieve the purpose of being able to quickly recover the funds as Yunfei originally envisioned, so he can only find another way.

As long as the industrial production process design of the 32-bit industrial control chip is completed, the dilemma that the company is facing may be solved...... (To be continued......)
