Chapter 321 Don't Go on the Road (Part 1)

Guo Tailai didn't take this little episode to heart. After going out to relax for a while, I came back to work more energetically.

Processing also consumes more energy, but it is much less than stimulating cell growth, at most ten times the normal consumption, relatively speaking, it has little impact on Guo Tailai.

The spare parts of the car have been built, and only the carbon fiber material is left. There is no way but to wait for the purchased carbon fiber board to arrive.

Long Fei's engine adjustment has made new achievements, the maximum power has reached 430 horsepower, and it is still being adjusted bit by bit.

In addition to debugging, it is more important to record the results of every parameter change. Wan Ming contributed to this point. He created an access file database by himself, and recorded every small change in it. There is no way, there is no original data, so I can only record a little bit by myself, which will be valuable information and experience in the future.

"Fatty, why don't you adjust it according to the limit power?" Long Fei actually wanted to modify violently a long time ago, but he had to take care of all kinds of balance, so he could only adjust it so carefully. This has always been a question in his mind, and Guo Tailai happened to be there, so he asked it casually.

"The materials are very rare." Why doesn't Guo Tailai want to change violently? But now the price of the wear-resistant and heat-resistant metals used to make the engine is too outrageous. Be careful!"

The twin-rotor 1.3-displacement engine had been modified at any cost to increase the power to 800 horsepower, but that was at the cost of greatly reducing the engine's lifespan. The service life of an engine that has been violently modified will not exceed one month.

If it was an ordinary material, Guo Tailai might play it that way, but with such a precious material, Guo Tailai didn't want to play it so short-lived, and tried to improve it as much as possible under the premise of ensuring the lifespan, but this also required more skills and more careful adjustments. school.

"How much is this material?" Long Fei didn't know what material Guo Tailai used to make the engine, but he knew the physical properties and many parameters, which were definitely beyond the reach of many special steels, so he asked curiously.

"When I got it, it was more than one million yuan per ton." Guo Tailai didn't hide anything, and directly stated the price at that time: "Maybe the price will be cheaper now, but you may not be able to buy it if you have money. I'm just afraid that I won't be able to buy it again." That’s why I saved a little bit of playing, otherwise we will also play a blast change.”

Hearing that one ton of heat-resistant metal costs more than one million yuan, even Long Fei, who often plays with cars, couldn't help being speechless. He used to modify some motorcycles frequently, but it was only tens of thousands of dollars. How can it be like Fatty, the materials of the engine alone cost tens of thousands of dollars? This is not counting the carbon fiber used for the shell. If the manual cost of the fat man is added, the price of this car is simply sky-high.

While chatting with Long Fei and watching him fine-tune the engine little by little, the phone rang suddenly, and Guo Tailai hurriedly picked it up.

"Master?" To Guo Tailai's surprise, it was Mr. Liu who called. Since Guo Tailai made shoes last time, Guo Tailai usually went to visit Mr. Liu after a while, but Mr. Liu never took the initiative to call Guo Tailai, so he didn't know what was going on this time.

"How much flatness can you achieve for a flat plate of 1.2 by 1.2 meters?" As soon as he came up, Mr. Liu asked Guo Tailai a professional processing accuracy question: "Can it be done below 5 microns?"

Although he didn't know what Mr. Liu was asking this question for, Guo Tailai answered honestly: "Absolutely flat? It can be done with a larger area, um, and the precision can be made higher."

"What about two meters by one meter five?" Mr. Liu seemed relieved to hear Guo Tailai's answer, and asked Guo Tailai again.

"Yes!" Guo Tailai gave an affirmative answer without even thinking about it this time.

Then Guo Tailai couldn't hear the sound anymore, it seemed that Mr. Liu covered the microphone and was discussing with others, Guo Tailai just waited quietly. After a while, Guo Tailai heard Mr. Liu's voice again.

"What if it's bigger, three meters by three meters?" Mr. Liu's voice sounded a little excited, and it was still a matter of machining accuracy.

"As long as the stress release is complete, the temperature is constant, and the support strength is sufficient, it's fine." Guo Tailai knew what Mr. Liu was excited about, and replied calmly: "Do you want to use a large-area ultra-high-precision grinding machine? The flatness can reach 1 Microns or so."

"Okay, I got it." Guo Tailai clearly heard Mr. Liu's long breath and his tone of relaxation suddenly: "The department has made some breakthroughs in design, but the processing and assembly can't guarantee the accuracy. , it’s enough to have your words. When you get ready here, you go back to the department.”

"Okay!" Guo Tailai immediately agreed without saying a word.

Absolute planes are mostly used for sliding surfaces of ultra-precision mechanical guide rails. Naturally, the higher the precision, the better. If it is said that 1.2 by 1.2 meters can be used for normal-sized machine tools, then the three meters by three meters mentioned later is Guo Tai's large-area grinding machine.

Mr. Liu has always been the instructor of the production and assembly of the experimental machine tool parts in the department. Now he still calls Guo Tailai to ask Guo Tailai, explaining that the precision of the machine tool grinding machine designed by the department must have exceeded Mr. Liu's control. Great news!

As long as these newly designed machine tools are introduced, it means that my country's machine tool production capacity will be further improved, and machine tools with higher precision than the original can be produced with this as the mother machine. This also means that the domestic machine tool industry will collectively upgrade.

Of course, Guo Tailai raised his hands to support such a great event. Guo Tailai, who has always been stingy, would not even mention the price, and would definitely offer to help. On the issue of right and wrong, Guo Tailai has never been ambiguous. From processing to assembly, Guo Tailai will definitely help in the whole process.

Of course, Guo Tailai is still conservative in terms of machining accuracy. Depending on the situation at that time, if you need to process in public, you can only use your hands to process to a precision of less than one micron. If you can process in a closed manner, you can directly use the highest precision.

Not long after putting down Mr. Liu's call, Guo Tailai received a call from Professor Wang. Professor Wang thanked him for developing a five-axis machining system according to the chicken head stability principle discovered by Guo Tailai. The accuracy of the operating system on the Internet, this is a bit of a fly in the ointment.

With Guo Tailai's affirmative answer, Professor Wang's design can really be considered for sample trial operation, so Professor Wang called Guo Tailai immediately to thank him.
