Chapter 317 the top of the world

This set of high-precision processing equipment in Zhangjiakou is the domestic five axis linkage machine tool that Nie Minhui helped Zhang Yunfeng to buy at the beginning. If we want to say that the former processing accuracy can't even meet the requirements of 0.5 μ m, which is dozens of times less than the 0.01 μ m of the world's top military industrial level. After this set of equipment is in Zhang Yunfeng's hands, coupled with the continuous upgrade and change of the second child, it is step by step Self upgrading, even reached the current level of 0.001 μ M.

Similar to this kind of high-precision processing equipment, it is impossible to draw any conclusion just by naked eyes. The best way is to give a drawing accurate to 0.001 μ m, let it actually perform a processing according to the drawing, and then measure the level of its accuracy through the final product.

These high-end scientists in the processing field are full of curiosity about the device, and they all hope to try to operate it in practice, but Zhang Yunfeng says there is nothing he can do about it, because the device is all controlled by the junior two.

Director Liu also knows that bringing these scientists and experts to Dongchen's high-precision processing center can't help us. But the first response is to let experts in the military industry come to watch and learn.

For the constant demands of those experts, director Liu could only stand up, refuse first and then appease, saying: "now this processing center is a high secret of the state. Our first task is to quickly and safely transport the equipment here to Jiangcheng. As for learning and observing, there will be opportunities later. In addition, Comrade Zhang has promised us that this processing center, We will do our best for our military construction. If you need to use this set of processing equipment for the project at hand, you can report it to the superior for approval. "

"If our project is approved by the state and we carry out high-precision processing and manufacturing in Jiangcheng, can our people participate in the whole process?" asked an expert in ship manufacturing

Liu looked at Zhang Yunfeng and said with a smile, "let Comrade Xiao Zhang answer this request."

Zhang Yunfeng smiled and said, "of course you can participate."

Although that's the case, Zhang Yunfeng knew that even if they participated, they could only provide preliminary data and drawings, and then stand aside to observe. All the processing processes are fully automated, and Xiaoer is fully responsible for the control of all the machinery and arms, without anyone participating.

All the equipment began to be carefully disassembled and packed into special wooden boxes, and then all the equipment was loaded into container cars. The motorcade drove back to Yanjing, but after entering Yanjing, the troops divided into two ways.

A car of experts who came to fight soy sauce directly went back to the city. Zhang Yunfeng and Liu Gan followed the transport team to yanjingjun airport in advance. They saw that all the equipment was loaded into an Il-76 transport plane. At one o'clock in the morning, five carefully selected armed police special police officers followed two crew members to board the plane. The plane took off from the airport without any delay and jumped into the sky.

Zhang Yunfeng didn't have much delay either. He returned to Yanjing airport with Director Liu, and they flew to Jiangcheng by private plane. After the plane took off, director Liu received a call. Later, he hung up the phone and said to Zhang: "there are armed police special police ready on the other side of Jiangcheng, and the plane will be directly pushed into the hangar which is requisitioned by the military And then transfer all the equipment in the hangar to the car for transportation. After we get off the plane, we will go to the industrial base of the high tech Zone together with them. Before dawn, all the equipment will be transported into the prepared factory. "

Zhang Yunfeng nodded and said, "this should not be a big problem."

Liu said with a smile: "the problem is that there is no news. The participating armed police officers are not only selective, but also undisclosed. They don't know what the goods are. In addition, you don't need to worry about these experts. Each of them has a very important national defense technology and reliability in their own fields It has been tested. "

Zhang Yunfeng said with a smile, "I'm not worried about this. As long as the process goes smoothly, I don't think it's shocking that I didn't disclose it to you before. Now even if I tell you, I can't disclose it. Otherwise, I'm afraid it's not peaceful."

Liu Ganshi nodded with approval and said, "by the way, the military has a commission. I wonder if you can help me?"

"You say," said Zhang Yunfeng

Director Liu said with a smile: "well, previously, Zhongchen materials have cooperated with the state. The new aluminum alloy and steel alloy materials, except for Dongchen's own use, are all purchased by the state. We have also started to apply these materials to our national defense technology products. We have been processing and producing them ourselves before, but now you have more Good processing equipment, so the military wants to give you a commission order, which is requested by the military, and Dongchen is responsible for processing and production. "

Zhang Yunfeng didn't hesitate at all and said with a smile: "there is no problem. Let the military give specific plans, parameters, drawings and other requirements."

Director Liu asked with a smile, "now, our biggest and most urgent demand is the aeroengine. The biggest problem of our self-made Taihang series fighter engine is that the processing accuracy is not enough. Many parts are troubled by this problem. The military means to give these parts to Dongchen for processing and production."

Zhang Yunfeng frowned slightly and said: "even if the technology content is relatively low, the manufacturing process will not change qualitatively no matter how high-end it is. Even if all parts are manufactured by Dongchen, the technology used is still the technology of Taihang series engine itself, so the engine will not be stronger than the former one, with limited benefits It means that the loss will be reduced and the service life will be increased. "

Director Liu smiled helplessly and said: "there is no way to do this, but after all, this is the best engine we have now. Even if we imitate it, we can only touch the engine of e country's aircraft, and it is not the best in their hands. As for the military engine of the United States, we even have very few opportunities to see it with our own eyes, and there is no way to imitate it "

Zhang Yunfeng hesitated for a moment and said, "I can accept this Commission, but it's better for the military to have psychological preparation. Even if Dongchen is responsible for processing, the promotion will not be too great."

Director Liu nodded: "in fact, even if it can only improve the reliability and service life of machinery, it is also a major breakthrough."

Zhang Yunfeng is thinking about when to ask for a ready-made engine production line with the senior management. However, Zhang Yunfeng is not interested in directly producing military aircraft engines, but gives priority to civil engines. The former is too sensitive to push Dongchen to the top of the wind, while the latter is relatively peaceful, and has a large market space.

Zhang Yunfeng's private business jet landed at Jiangcheng airport. At this time, a large hangar of Airbus A330 had been commandeered and guarded by the special police of the armed police. Zhang Yunfeng's private jet was pushed to the hangar next door. After getting off the plane, Zhang Yunfeng and Liu Ganshi hurried to the hangar on the other side of the wall. After confirming that all the equipment had been loaded into the car, the two also sat on one Armed police off-road vehicles, directly to the high-tech zone.

During this period, Dongchen was busy in the industrial base of the high tech Zone, with large vehicles coming in and out, and a large number of people fighting day and night here. Therefore, no one was surprised by the extra team. After entering the industrial base, these container trucks drove directly to the customized factory that Zhang Yunfeng had already prepared.

Before daybreak, all the equipment had been transported into the new workshop, and some professionals began to be responsible for installation. Zhang Yunfeng was not worried about this. Five axis linkage machine tool is not a rare thing in China, and the real strength of this equipment is not visible.

It took a whole day for the equipment to be erected. Liu Ganshi returned to Yanjing to report the situation to the senior management. He will assist the general manager to summarize all the processing needs in the military industry and make a time priority order according to the priorities.

At this time, Zhang Yunfeng has a chance to do his own things.

The high-precision machining center starts to work again. This time, the product is an engine to be equipped on the SC1, a 12 cylinder metal monster with a displacement of 6.0l and a V-shape arrangement.

In addition to the engine, Zhang Yunfeng also intends to build a 10 speed dual clutch gearbox with excellent performance and leading technology. This gearbox is the perfect match for engines with 6.0l and above displacement. In other words, only such high-end gearbox can match the super engine with more than 1300 horsepower. After the combination of the two, it is a surprise People's power output, torque output, as well as speed and strength of the rapid conversion, coordination.

Nowadays, there is not a really mature 10 speed gearbox in the field of cars. Although BMW has made a very attractive 10 speed gearbox several years ago, this gearbox is still not applied to mass production vehicles a few years later.

The core reason is that the 10 speed gearbox manufactured by today's technology is too large!

The huge size makes its volume much larger than the general 6-speed or even 8-speed gearbox, which means that the cars that need to use 10 speed gearbox generally are super running big killers with the pursuit of speed as the limit, while the power of big killers is high, but they need to be fully applied to the speed, it can not have too much self weight, otherwise, it will backfire.

In addition to the large volume and weight, immature technology is also the root cause that 10 speed gearbox can not really enter the practical application field. In addition, the structure is more complex and the number of parts is almost multiplied, which makes the failure probability of this gearbox large, maintenance difficult and the cost extraordinary high.

Combined with the above factors, BMW's 10-speed gearbox has become a gimmick in a short period of time. Other brands, starting from the reality, have given up the process of developing 10-speed gearbox. The most advanced and widely used multi-speed gearbox is maintained at 8-speed, because the technology of 8-speed gearbox is relatively mature.

The 10 speed gearbox technology Zhang Yunfeng will bring out is the most mature and outstanding set of 10 speed gearbox technology. The total volume and weight are basically similar to the 8-speed gearbox now, but its performance is very outstanding. Even in the next 20 years, no one can match it.

This gearbox will be made of special steel alloy unique to Dongchen, which hasn't appeared in 30 years, so this
