Chapter 177

Lathe is the real mother of industry. All milling machines and drilling machines are improved from lathes.

Lathe machining is mainly the rotary motion of parts and the linear motion of cutting tools; The milling machine is a rotary motion of the cutter and a linear motion of the parts. Lathes and milling machines are the most widely used machining equipment in the world.

Although it will be gradually replaced by CNC lathes, machining centers and other professional CNC machine tools in future generations, no matter how they are improved, CNC lathes are still lathes. There is no change in the processing principle with ordinary lathes, but the tool change and advance / retreat manually operated by workers are replaced by computer chip control.

The machining center is the same. It also changes the manual operation of ordinary milling machines into computer chip control.

Lathe is the earliest machining and cutting equipment in the world.

The original lathe appeared before the British Industrial Revolution. At that time, it was only used to process some rotary parts with wood as raw materials. It is said that at that time, the earliest simple lathe in Britain was mainly used to process the axles of carriages. However, at that time, due to the problem of machining accuracy, the structure of the lathe was very simple, even rudimentary. Of course, the machining error is also calculated in millimeters.

With the promotion of the industrial revolution, various mechanical equipment had higher and higher requirements for accuracy. As the main machining equipment at that time, the lathe was constantly improved. With the continuous development of mechanical equipment, new equipment and raw materials, the requirements for cutting machine tools are higher, and the lathe will gradually become mature.

The first lathes used in the industrial revolution were powered by steam engines.

In a lathe processing workshop, the lathes are neatly arranged. At the top of the lathe head, there is a huge shaft with a belt pulley hanging on it. In other words, several lathes use the same transmission shaft. As long as a lathe runs and uses the same transmission shaft, the lathe must start as long as it does not hang the belt. Moreover, the machine tool started can not be changed manually in the processing process.

According to the parts with different diameters, the speed of the lathe must be adjusted before the machine tool starts. If you want to adjust, only stop all lathes driven by that drive shaft.

At the back, with the emergence of motors, the lathe was really mature. Each lathe has an independent transmission system.

"Brother Yunfei, I heard that many factories in China are producing lathes, and many factories are not very effective." Although Ni Lishuang, who has been staying in the hospital and determined to become Yunfei's mentor since childhood, has always been concerned about Yunfei.

Since she knew that Yunfei took over 9327 factory, although she didn't know where Yunfei came from so much money, she was smart and didn't ask about it. Many people are not optimistic that Yunfei wants to produce machine tools, but she still silently supports Yunfei. During her days in the hospital, she constantly asks the Mao sisters to help her buy magazine papers on company management or machinery.

Since childhood, although she didn't receive professional training from the old men like Yunfei, she also listened to a lot. She doesn't want to know nothing about what her brother Yunfei did when she grew up.

Although I know a lot about the basic knowledge of machinery, I don't know anything about management. She went to technical school as an accountant. Yunfei has revealed to her that she wants to be the CFO of the whole company. Although she also wants to be the chief financial officer of a factory with thousands of people, she also knows that with the basic accounting knowledge she learned in the technical school, it is difficult to do even the most basic financial statements. It is impossible to manage the finance of a company.

If those old accountants under her hand collude to do things on the book, she can't bear the responsibility without experience.

"You don't understand this. Although there are many factories producing lathes, their production experience is richer than ours. However, lathes are also the most used machine tools in the world, far more than milling machines and planers. We have just entered the civil machine tool market and can only produce lathes with the largest consumption, which can not only better open the market, but also the funds for machine tool sales can enable our factory to have more funds to invest in the development of new equipment. " Yunfei has not explained to anyone why he produces the most lathes from domestic manufacturers as soon as he comes up.

The reason why Yunfei wants to produce lathes at the beginning is not only because Yunfei has many contacts in machining in the Pearl River Delta. Lathes can bring more funds to his company. More importantly, if you want to engage in CNC machine tools, CNC lathes are entry-level CNC machine tools.

As long as the ball screw is made and the stepping motor is used, it can produce a simple CNC lathe that still occupies most of the market share in the domestic market when Yunfei leaves his world.

The production of simple CNC lathes can not only accumulate a lot of production experience, but also develop towards precision CNC lathes. Similarly, with a lot of profits brought by CNC lathes, CNC milling machines will have more research funds.

Yunfei doesn't want to produce CNC milling machines or more advanced CNC machining centers as soon as he comes up.

However, there are so many engineers and technicians from the Soviet network. Although many of them also have research experience in NC machine tools, Yun Fei really scoffs at the Soviet Union's technology in NC technology.

They went in the wrong direction, even farther than China.

Although China has also followed the big brother of the Soviet Union in the wrong direction in the research of CNC machine tools, due to its poor foundation and weak foundation, China has not gone far in the production of special aircraft assembly lines. Now, if we want to develop numerical control technology, we only need to understand the development direction of numerical control technology in Europe and America. Although China has no foundation and weak foundation, it is very difficult to study, but it will not be replaced by inertial thinking like the Soviet Union.

Yun Fei also knows that it is impossible to expect these electrical engineers from the Soviet Union to study CNC machine tools. The company will produce the first batch of CNC machine tools. He will use the Dragon CNC system produced by Huadu CNC. That system was originally copied by him, which is completely enough for CNC machine tools with low precision.

Yunfei doesn't want to be hostile to foreign CNC machine tool manufacturers when he just started and was fledgling.

He knows that if he works with foreign CNC machine tool manufacturers, Taiwan machine tool manufacturers will certainly act as cannon fodder for foreigners. At that time, if you are black and blue because of fighting with Taiwan machine tool manufacturers, any company that exports CNC machine tools to China will be able to destroy its own 91 heavy industry.

Now the production of domestic CNC machine tools has begun to become hot because of the emergence of dragon CNC. Yunfei, a newly established factory, can develop quietly as long as it doesn't produce machine tools that far surpass other domestic machine tool manufacturers in the same industry. Waiting for the strength to be gathered and suddenly burst out, it will definitely make those foreign NC machine tool manufacturers occupy half of the country when they don't respond.

On the network above his world, Yunfei has also seen many analytical papers of the so-called brick house and beast, but he scoffs at them.

Many people believe that as long as Chinese machine tool manufacturers unite, they can compete with foreign machine tool manufacturers.

This is not feasible at all. In China, where everything is decided by the state, if this can really make China's CNC technology develop rapidly, will the state not support this?

If the whole country boycotts foreign CNC machine tools, it will be retaliated by all foreign CNC machine tool manufacturers.

Everyone knows that China cannot produce the most high-end and super precision CNC machine tools, but if domestic industries want to develop, especially the manufacturing of high-precision and cutting-edge production equipment, China can't process them without those high-end CNC machine tools.

China needs foreign high-grade CNC machine tools. Although the CNC machine tools sold to China can never be the most high-end, they are not the most high-end CNC machine tools, and China can't produce them.

Therefore, even in the era of Yunfei, due to the rise of some CNC machine tool manufacturers such as Huashu and the capital, they occupied half of the domestic CNC machine tool market, and even occupied most of the domestic market share in the low-grade CNC machine tool market.

Even under such circumstances, no one dared to propose to squeeze foreigners out of China from low-grade CNC machine tools.

Under the trend of such an environment, the cloud can only keep a low profile. We can't be like those walkers in the online article. When we first arrive at an era, the whole world has to surrender as soon as the aura of the protagonist shines. Catching up with the United States in the Premier League is something that can be completed in minutes. Cloud is not a real strider. When he comes to this era, he understands that people in any era are not so simple.

Unless, as the protagonist, he takes the best artifact with him, all technologies can appear out of thin air without too many people.

Even with technology, no production experience and insufficient technical level of workers, it is impossible to produce at all.

Take Yunfei now for example. He has a lot of design concepts of CNC machine tools. He also saw physical objects and understood detailed functions in his own era, but only after understanding this era did he understand that with design drawings, he can turn drawings into reality.

This is why China has been imitating foreign high-precision and cutting-edge machine tools, but it has never been able to achieve the accuracy of foreign imported machine tools.

Not only because of materials, but also because of assembly technology.

Therefore, Yunfei still has to start with the most basic lathe. Lathe is the basis of all machine tools. Only when we understand the lathe thoroughly can we gradually realize the accumulation of technology for other equipment.
