Chapter 198

"I've thought about it carefully these days. There was no big deviation in our original strategy, so we have to continue to work on CNC lathes, not only to do it, but also to make the best. What is the best? The lathe with stepless speed change in high, middle and low gears is not the best. We must produce the CNC lathe with stepless speed change. Only in this way can we regain a firm foothold in the chaotic CNC machine tool market! "

Yun Fei finished and hit his hand heavily on the conference table.

The participants, hearing Yun Fei's words, all looked embarrassed. In particular, savavsky, the head of the technology department, was even more embarrassed.

Simple CNC lathe is easy to do. As long as the ordinary screw rod and polished rod are replaced with ball screw rod, and then the tool holder connected with special high-precision toothed disc is installed, and the CNC system is installed, a simple CNC lathe is completed.

But the CNC lathe with stepless speed change in three gears and a full range of stepless speed change is not such a simple problem. Except that the machine bed can barely retain the bed structure of the ordinary lathe, the gears in the whole headstock have to be replaced. This is not only a matter that can be solved by changing gears, but also has all kinds 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 simple CNC lathes.

"We should not only increase the research on high-precision CNC lathes, but also speed up the research on CNC milling machines and even machining centers. We must launch our products within half a year, otherwise, the CNC lathe produced by our company can only fall into a protracted price war with other CNC machine tool manufacturers. They have the national financial blood transfusion. We don't. If we can't launch high-precision CNC machine tools within half a year, our Jiuyi heavy industry can only go bankrupt or be acquired. "

Yun Fei said finally, incomparable loss. Today's Jiuyi heavy industry is not only his whole wealth, but also carries all his dreams. In order to produce high-precision multi axis CNC machine tools in China, we must accumulate experience and develop step by step from the lowest two axis CNC lathe and the entry-level three-axis CNC milling machine.

As long as a three-axis CNC milling machine is produced, it will become a machining center only by adding a tool magazine that can automatically change the tool in the CNC milling machine. Although it is very difficult for other CNC machine tool manufacturers in China to install a tool magazine, it is not very difficult for Yunfei from later generations.

"Why, old SA, what's the problem?" Yunfei saw that the eyebrows on both sides of savafsky 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 translation, savafsky also knew the problems facing the company.

CNC milling machines have started theoretical research and design since they first came to Chengdu and were still in the hotel, but up to now, there is no way to solve the accuracy control of z-axis movement of the most basic machining center.

People who know CNC milling machine or machining center know that the most key technology of CNC milling machine is on the z-axis that can move up and down. Positioning accuracy is controlled by CNC system and ball screw.

For ordinary milling machines, except for the rotation function of the spindle, all the movement of the spindle is on the workbench. However, CNC milling machines cannot do this. High precision CNC machine tools, especially when positioning quickly, have a self weight of more than one ton on the worktable. If you add hundreds of kilograms of parts or no parts, it will also cause great damage to the transmission ball screw.

The emergence of NC milling machine itself is to process some complex parts. But where is there so much processing of large quantities of complex parts in the world? Therefore, in the use of machining center, the powerful machining ability and machining efficiency of machining center in the milling of large quantities of parts were discovered shortly after the birth of NC milling machine.

Ball screw can be like ordinary transmission screw, which is far from being compared in terms of thread width, and can not drive the worktable in the ton to move quickly in the vertical direction.

Therefore, both CNC milling machines and machining centers can only use the worktable to move back and forth, and the spindle with very light weight can move up and down.

"Why? Aren't you from the Institute of machinery? Don't tell me that a few months have passed and the design of NC milling machine has not been completed yet! " Yun Fei is really angry.

In the past, when reading online articles, countless piercers and reborn people were calling the wind and rain and catching up with each other in their world. But I didn't realize that in this world, I am confident that I can do a lot. Even if I can't catch up with the United States, it will take at least ten or twenty years on CNC machine tools, so that at least domestic machine tool manufacturers can provide some high-end CNC machine tools.

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

God, are you kidding me?

"Boss, you originally told us that we don't have to worry too much about the design and research of NC milling machine, so we put all our experience into the research of NC lathe..." savavsky's voice became smaller and smaller.

He felt sorry for them, which gave them hope when they were starving and gave them absolutely high paying jobs in the Soviet Union. Although he was far away from his motherland now, with the most superior living conditions given to them by the young boss in Yunfei, he was able to bring his family to China to live.

In Soviet research institutes, they were able to complete the design tasks assigned by their superiors under the condition of extreme material shortage. In China, is it the superior life that makes them lose their motivation?

"I said that, but I also tell you that CNC milling machine is related to the strategic development of the whole company for decades. Why are you a professional machine tool research organization in the past few months? Is it really so difficult to design the mechanical part of a CNC milling machine?" Yunfei's words are getting louder and louder.

At the beginning, these old maozi still had a sense of crisis and did little serious work. It turned out that Yunfei thought that these old maozi who had left their hometown were worried about losing their job and returning to the territory of the Soviet Union to continue to suffer from cold and hunger. But unexpectedly, their seriousness returned to the state in the Soviet Union within a few months.

The laziness of the old maozi of the Soviet Union is famous. Especially when the cold war between the Soviet Union and the United States is coming to an end and the whole country is in poverty, the operating rate of large and medium-sized industrial production plants and machinery research institutes throughout the alliance is less than 30%! Russia under Yeltsin's control gradually cut off the blood transfusion to major research institutes and machinery factories in non Russian countries in the whole alliance.

In the whole conference room, everyone was uncomfortable. Yun Fei, the young boss, was like a mad dog under great pressure. He was basically catching who and biting who!

"I really don't understand what your achievements have been in recent months. Most of our ordinary lathes have mature drawings. You just made some basic improvements; The testing machine of our company's CNC lathe is only the lowest CNC lathe, and there is no much improvement; Are you dozens of people, this is a little bit of time in these months? " Yun Fei basically growled at savavsky.

These words also embarrass the leaders of other departments.

Starting from the company, Yunfei has endless things to deal with every day. He doesn't intervene in the management of various departments at all. Perhaps this is because he is young and doesn't have management experience in large factories. But these managers with absolutely high salaries also muddle along.

"In short, I don't care what you do. Within a month, I must see the design drawing of the NC milling machine appear in front of me. All departments must seriously cooperate with the technical department. Otherwise, I will make room for people with ability." After Yunfei finished, he left angrily.

At present, the only way is to find situ Heyun and sun Lin.

Yun Fei didn't bring these two old guys here to let them just get out the simple rotary table driven by PMC module hung on the machining center.

You know, the biggest customers of that set of products in China's mechanical processing are only military factories, and there are not many four-axis processing centers used for civil products. Yunfei knows that the CNC machine tool market is far from being comparable with a single spare part. So Yun Fei generously gave the set of rotary worktable to Zhao Xingbang's factory for production. For each set of rotary worktable, he only charged the so-called patent fee of 10000 yuan.

Yun Fei also knows that patent fees are just a piece of bullshit in China, especially in China in the early 1990s! Otherwise, after nearly three decades of intellectual property rights in China, in addition to some of the top things that can't be copied in China, as long as they can make money and have a market, they can find high-quality and cheap fake products in China.

The Electronic Research Institute under tanaliya is conducting an industrial production test of the 32-bit industrial control chip that Yunfei copied from the future market in recent months. According to the female engineer herself, it is about to have an eyebrow now.

Now there is a problem with the CNC lathe, which can not achieve the purpose of rapid recovery of funds originally envisaged, so we can only find another way.

As long as the industrial production process design of the 32-bit industrial control chip is completed, the dilemma facing the company may be solved
