After seeing Yuan Xuedong leave, Duan Yun frowned.

On the surface, Yuan Xuedong seemed to be courting him for peace, and Duan Yun understood that he was not that kind of person at all.

This product must still not let go of the hatred of taking away the position of the manager of the labor service company in the first place, and must have other plans in his heart.

But now Duan Yun is in the limelight, whether in the city bureau or in the factory, he is a hot figure, and it is very difficult, even impossible, for Yuan Xuedong to move him.

But the heart of guarding against people is indispensable, Duan Yun still has to beware of Yuan Xuedong's traps and methods.

After leaving the main factory, Duan Yun returned to the labor service company.

Changing into overalls, he walked straight to the workshop.

At present, Duanyun's gearbox test platform, the modification is nearing completion, only some lines are connected, and it is estimated that everything will be completed before the end of work this afternoon.

With this automotive transmission test platform, the R&D and testing of Duanyun's new products will become very efficient.

At this point, Duan Yun has initially established a relatively complete product performance and quality inspection system in the labor service company, and has also initially equipped the team and equipment for efficient research and development of new products.

Although he successfully completed the goal of producing the leading domestic automobile transmission products issued by the municipal bureau this time, Duan Yun's ultimate goal is to enter the international market.

This is a very difficult task, and it can be said that it is basically impossible, because with the current domestic industrial system, it is impossible to support the production of world-class products.

No matter from the equipment raw materials or personnel, the country is at least behind the international for more than ten years or even twenty or thirty years, in terms of CNC machine tools, in the early 80s, the penetration rate of Japanese CNC machine tools has reached 83%, and the domestic proportion is not even 3%, basically concentrated in some national key military enterprises and R & D institutions, even if the CNC machine tools there are not the world's top, are just some international ordinary CNC lathes.

In the 80s, that is, in 83 this year, there was a high-end lathe export incident that shocked the world.

Before the 80s, the machining accuracy of the Soviet CNC lathe was not high, in the production of military submarine propellers, because the machining accuracy and surface finish could not meet the design requirements, so when the propeller rotated, there would be a lot of empty cannons, causing noise, and to eliminate or reduce the noise, it was necessary to ensure the machining accuracy of the propeller, simply put, the curved surface must have a continuous error to be small, which requires a high-precision lathe with multi-head linkage, and the next molding under computer control, and the Soviet Union did not even reach the third-rate level in this regard, so it was naturally impossible to process a qualified submarine propeller。

In 1970, the Soviet Union negotiated with the Italian company Danieli to buy a CNC lathe for processing ship propellers, but it was blocked by the Americans, who obviously did not want the Soviet Union to have such high-precision propeller processing capabilities.

But the Soviet Union did not stop there, they found the Japanese Toshiba company, with a high price of 3.5 billion yen to buy 4 high-precision CNC lathes, at that time the Japanese Toshiba company was secretly happy, they could not have imagined, 4 small machine tools were sold at such a high price, but in this transaction, the Soviet Union is the biggest beneficiary, they obtained can not be measured by money at all.

Due to the embargo of the Paris Coordinating Committee, Japan could not directly ship lathes to the Soviet Union, so Japan used Norway as a transshipment station, because Norway is a NATO country, so it would not violate the ban, so in the middle of the night in 1983, Japan's Zhipu Terminal transported 10 boxes of machine tool parts, which was the "Toshiba Incident" that shocked the world.

In the end, these four small machine tools changed the situation in the United States and the Soviet Union, so that the US Navy instantly lost the advantage of detecting the hydroacoustics of Soviet submarines.

In the early 80s, although the relationship between China and Western countries tends to ease, the United States has also opened up some high-tech products to the country, but for high-end machine tools in the field of military industry, Western countries have been blockading the country, even if they sell some more ordinary civilian products, they will never take out the top good things to sell.

Any of the world's top car manufacturers has a core technology that cannot be acquired through direct purchase unless it is acquired and merged, which requires a lot of money and is also hindered by Western governments.

With Duan Yun's knowledge and ability, he can design the leading automobile transmission in the 80s, when he was studying for a doctorate, he had seen a lot of international advanced automobile transmission samples and drawings at that time, and was deeply impressed by the design of several mainstream automobile transmission products in the world.

Of course, as far as the current situation of domestic machine tools and equipment is concerned, even if Duan Yun has mastered the design drawings of the automobile gearbox in the future, it is impossible to produce these things, and the raw materials and equipment are not up to standard, which means that these advanced designs in later generations can only be in the air.

Therefore, there are many things that need to be done to make a car transmission segment cloud that can enter the world market.

Now that the sample of the "Longteng" gearbox has been made, the next step will be to gradually optimize the process, reduce production costs, and prepare for mass production.

On the other hand, Duan Yun will also draw some car gearbox drawings he saw in his previous life through memory, temporarily as a technical reserve, and after better equipment is in place, Duan Yun can start to develop more advanced car gearboxes.

Later generations of automobile transmissions are basically automatic transmissions, and manual ones are also available, but the market share is not large.

As far as the current domestic situation is concerned, the production cost of automatic transmission is too high, and it is not very inconvenient to maintain, which is obviously contrary to the requirements of the Chinese people for the car, the price is low, the leather is durable, and the maintenance is convenient, so sometimes the advanced technology is not necessarily suitable for the national conditions of the country.

But Duan Yun's ultimate goal is still the international market, so he must take the road of developing automatic transmissions, in the current equipment technology and funds are not in place, Duan Yun needs to find another way, think of other ways.

High-end lathes need high-end spare parts, and Duan Yun has no way to obtain these high-end machine tool parts through formal channels, so he needs some other special ways.

Compared with Japan, Europe and the United States machine tools, the level of Taiwan's machine tools across the strait is slightly inferior, but it is also far higher than the domestic level, Duan Yun's next plan is to set up an office in Xiamen, and then through some underground channels, with the means of ant moving, step by step to obtain high-end equipment that cannot be obtained through conventional channels.
