Peng Huading had to admit that what the other party said made sense, and he couldn't help but feel depressed.

Originally, he wanted to cooperate with this aviation machinery company, and all the machining processes were handed over to them, and he only needed to do heat treatment with peace of mind. Who knows that people are not very stable, and they are not willing to give themselves large profits.

He said to himself: "It seems that it is not as simple as imagined that I want to make high profits. Not only do people want to dig a big chunk out of it, but they also covet my skills. ......, I have to find a way to get rid of this dependence, at least let the other party know that I have another way to go and I don't have to rely on them, otherwise, I don't know if I will be pressed by them in the future. ”

Thinking that he couldn't process the gears by himself now, he had to give up his original fantasy and said: "Your offer is too high, a set of gears will give you a maximum of 8,000, a set of crankshafts will be up to 5,000, and I can also hand over the machining of all flanges to you." ”

After some bargaining, the two parties finally agreed to sell the gear for 10,000 yuan and the crankshaft for 7,000 yuan.

After signing the contract, at the request of the other party, Peng Huading took Deputy General Manager Wei and his party to visit the site of Yunfeng Company for a while.

Because the site is under construction, and there are only a handful of things inside, and they don't have a keen eye, they naturally can't see the secrets inside the vacuum furnace and quenching furnace, thinking that it is just ordinary heat treatment equipment, so they left after turning around.

In their opinion, Yunfeng Company is definitely not a place to heat treat gears here, and the heat treatment they don't know must be carried out elsewhere, and this is just a place to hide people's eyes.

When leaving Yunfeng Company, Deputy General Manager Wei said in his heart: "He is so mysterious, and he resolutely does not let us know, and it is the S-O6 method that is adopted." ”

For this method, he is not sensitive, not to mention the need to pay patent fees, which requires a lot of costs, and what is more troublesome is that because of the strict environmental pollution, he may be heavily fined by the environmental protection department, and the amount of the fine is greater than the profit, and the gains outweigh the losses.

Even if Peng Huading and they use the S-O6 method, it is better not to ask too clearly, and when the relevant departments punish Yunfeng Technology Company in the future, public opinion may still think that his aviation machinery company is an accomplice of Yunfeng Technology Company and damage the image of his company.

Because of this thought, they used the excuse that they had other business to discuss in the provincial capital, so they said goodbye to Peng Huading and left without even eating lunch.

Looking at the back of their departure, Peng Huading, who got the other party's contract, did not have much joy.

If Wang Lu hadn't told him the price quoted by the other party to her import and export company, Peng Huading might have been grateful to them and would have been glad that he was able to sign a contract with them, but now they used the method of coercion to make him unhappy, and he felt that they had taken out a large amount of money from their pockets.

Thinking that he might still be affected by this kind of pressure in the future, Peng Huading decided to find a way to solve the machining problem of gears and crankshafts, or find more companies that can undertake machining, otherwise he will always be controlled by others.

"Do you buy a precision machine, hire a senior mechanic, or find another way?" Peng Huading thought silently, "If this is the case, I will have to spend a huge amount of money to buy precision machine tools, and I will get other companies to dig up excellent technicians." It's not easy......"

At present, the factory to improve the dimensional accuracy, finish, flatness and other technical parameters of the surface of the part, generally take after many rough machining and then carry out many times of fine turning, fine grinding and other processes, and some also carry out polishing, shot blasting and other processes.

But Peng Huading knows that it is not only this way to improve the accuracy of parts, but also a simpler way is 3D printing. However, Peng Huading checked a lot of information before and knew that the current 3D printer still has great limitations, and it cannot print precise and sturdy parts at all, and many of them are still only in the conceptual field, at most they are printing some stupid, big and thick things.

He felt that a compromise method should be adopted, using a method called "laser-aerosol diffraction etching and melting" to solve the excess raw materials on the parts, and the "alloy metal fiber growth method" to solve the lack of raw materials on the parts.

To put it simply, when there is too much raw material in a certain part of the part, such as a crankshaft made of 45 steel, its diameter exceeds the specified tolerance standard and is unqualified, the "laser-aerosol diffraction etching melting method" can be used to melt and blow away the excess 45 steel, so that the diameter of the crankshaft becomes smaller and reaches the specified tolerance range.

On the contrary, if the diameter of the crankshaft made of No. 45 steel is less than the specified tolerance standard and is unqualified, an alloy fiber can be generated on the surface of the crankshaft to replace the original surface, so that the diameter of the crankshaft is increased to meet the specified standard.

These two methods were carefully selected by Peng Huading from the advanced technology in his mind, because although they are more advanced than the current science and technology, they are not much more advanced, and some advanced countries are studying these two topics, and a few countries have made some progress in the practical room, but they have not yet reached the practical level.

The application of laser has long been extensive, and laser cutting and laser ablation have also been applied to machinery, medical treatment, chemical industry, automation and other fields; Metal fibers are also not uncommon, and they are being studied in many countries and universities.

Peng Huading is just deepening their functions.

Originally, Peng Huading didn't want to rush to launch this kind of technology before, worried that others would bring trouble to him if they knew, but stimulated by today's incident, he decided to quietly use some edge technologies and use some technologies that can be connected with the current scientific level.

If this equipment can be used, then you can hand over the gears and crankshafts of the French VoRou company to any ordinary mechanical processing factory for rough processing, and you can use this equipment to refine it after it is shipped back, so that its quality can meet higher requirements.

Peng Huading said that he would do it, and buried his head in the network again, looking for electromechanical equipment that he could use: such as laser generators, stepper motors, and microwave devices......

In order to prevent leakage of secrets, Peng Huading also decided to build a closed processing room with bulletproof glass in the factory and adopt the method of computer remote control. To do this, he also had to design a computerized control system.

If these tasks are handed over to someone else, even if that person is a doctor of mechanical and electrical engineering, it will be difficult to complete, but it is not difficult for Peng Huading, he is only difficult how to buy suitable parts, chips, electromechanical equipment, and how long it will take to assemble successfully.

Just when Peng Huading was thinking and preparing to get rid of the constraints of Hudong Aviation Machinery Co., Ltd., the three people of Hudong Aviation Machinery Co., Ltd. were discussing how to figure out whether Peng Huading's heat treatment method was S-O6.

"Mr. Wei, the main work of parts and components depends on us, they are to do heat treatment on gears and crankshafts, and our asking price is still lost." The marketing manager said angrily as he smoked a cigarette.

Deputy General Manager Wei sneered: "Lost? Do you have such a high price for machining gears for other companies? What if the price is too high, and people really go to other companies to help them process it? ......, I tell you that the processing price of gear crankshafts is not low, but how can we learn their methods. I see that he is full of confidence, and it doesn't seem to be the S-O6 method taken. If you really want to use this method, he will not be able to eat and walk around in the future, unless he is very hard behind the backstage. ”
