Chaoshen Technology Trading Mall

In the end, Donald spent 15 energy coins to order a ton of special heat-resistant glass from Wang Bin, ranging from 0.5 mm to 12 mm. Compared with the quantity he bought over 5 mm Quite a lot, and according to the agreement between the two of them, Wang Bin must complete the transaction within three days.

When Donald walked out of Wang Bin's shop, Wang Bin was also preparing to quit the technology mall. After all, their Tiangong Technology's production capacity is only so small now, and they still have to supply 969 Group and Qin's Industry, so even if they keep some for themselves every day, At most, it's just over a ton.

What's more, their factory has just started construction now, there are not enough workers, and the production capacity is even less pitiful, so even if they sell some special glass in the technology mall, Wang Bin still has nothing to sell now.

However, just when Wang Bin was about to quit the technology mall, he suddenly thought that the system rewarded Wang Bin with special glass technology during the novice task before, so does that mean that he can also buy Kanxing and Red Police from the system? technology.

So I immediately asked the system: "System! Can I still buy technology in the worlds of Kanxing and Red Police? Do I need to buy technology from the technology mall stores in the worlds of Kanxing, Red Police, and Empire, or directly from the system? ?”

"Dear host, since Kanxing, Red Police, and Empire are all small universes, there are no technology mall hosts in these worlds. Naturally, there are no stores in these worlds in the technology mall, but there are some people in their world who can come to technology. mall.

Just like the two customers who came to your store to buy things before, and the technologies of these two worlds have basically been sold to the officials of the technology mall by these people, especially the technology of materials, so if the host If you want to continue to purchase the technologies of these worlds, you can purchase them directly from the system. "The system said.

After listening to the system, Wang Bin finally felt relieved. After all, with the current technological level of human civilization and the situation of their Tiangong technology, the technology of these three worlds is the most suitable, so he was a little worried before. Once completed, technology can no longer be purchased from Canstar, Red Alert, and Empire.

Then Wang Bin said to the system: "Can I have a look at the technology and prices of Kanxing's other basic materials?"

Although Wang Bin had obtained special high-temperature-resistant technology from the system before, Wang Bin did not spend any energy coins for this technology, but a novice reward from the system.

"Yes!" As soon as the system's words fell, Wang Bin saw the technology and price he wanted to see in his mind!

"Kanxing Aerospace's primary re-entry module shell material technology!

Maximum high temperature resistance: 2400 degrees.

Maximum impact resistance: 50 meters per second per square millimeter.

Maximum anti-overload: 50g.

Maximum compressive strength: 14000 kPa.

Moh's hardness......

....

....

The purchase price is 15,000 energy coins.

Kanxing's primary aircraft skin material technology... 16,000 energy coins.

Kanxing bearing steel smelting technology: ... 110,000 energy coins.

Kanxing tire technology... 18000 energy coins.

....

Wang Bin looked at Kanxing's material technology for a while, and he found that among Kanxing's material technologies, the cheapest one cost 16,000 energy coins, and that was the return cabin skin technology. And it is also the most basic skinning technology for the return capsule.

And the price of those high-end material technologies in Kanxing is even higher, which is not something that Wang Bin can afford now. In addition, the material technologies in Red Police and Empire are much cheaper, but at present the earth does not have or performance Those that have not reached these material levels are basically priced above 12,000 energy coins.

And those outdated technologies are much better, basically there are only tens of hundreds of energy coins, and even a few energy coins.

Of course, for the current earth, Wang Bin still has some disdain for technologies that are outdated or already available.

After watching for a while, Wang Bin quit the system. After all, he doesn't have any energy coins on him now.

Of course, for him, the most important thing now is to thoroughly understand the special glass technology, make it bigger and stronger, and at the same time develop their Tiangong technology first.

Afterwards, Wang Bin withdrew from the technology mall and returned to reality.

When he returned to reality, he found that only one minute had passed, and he had been in the technology mall for more than an hour!

In other words, one hour in the mall is equivalent to one minute in reality, which makes Wang Bin a little happy. After all, if the time in reality and the technology mall are synchronized, there is no time for him to stay in the mall. shop.

....

Wang Bin's office, when he went to work at nine o'clock the next morning, Wang Bin was already in the office. Wang Bin's office is not big, and many things in it look old and old-fashioned. It's out of date with this era.

In the office, Wang Bin stood by the window and looked out of the window at the factory area. It was the time when they were working at Tiangong Technology, so he could clearly see that many of their factory workers were entering the factory from the outside, and then clocked in. workshop.

After looking at it for a while, Wang Bin turned around, sat in front of his office, and checked the equipment for processing ball screw on the computer.

In the process of inquiry, Wang Bin found that the ball screw is also divided into different grades according to the precision, and there are differences between domestic and foreign ones.

The domestic grade accuracy is divided into seven grades: P1, P2, P3, P4, P5, P7, and P10. Among them, the accuracy of the p1 grade is the highest, and the stroke variation within any 300mm stroke is 4 microns, and the second grade is 6 microns. , Class 3 is 9 microns, Class 5 is 23 microns.

Of course, Wang Bin can't afford the p1 and p2 screw production lines at all now. After all, p1 and p2 screw production equipment cost at least tens of millions of dollars, and at the same time, after processing, a series of For follow-up processing, in order to ensure the accuracy, general processing equipment is not enough at all, it must be the top international equipment, and the price of these equipment is also very expensive, even if you have money, you may not be able to buy it.

Of course, the most important thing is that Wang Bin's Tiangong technology does not use ordinary screw materials or metal materials to process ball screws, so even if Wang Bin can buy these processing equipment, he can't use them. So Wang Bin is going to buy a set of high-precision CNC machine tools that can be bought in China, and then process some to see how the effect is.

After looking on the Internet for a while, Wang Bin found that the best high-precision machines are produced abroad.

In China, although in the past few years, due to technological breakthroughs, it has been possible to manufacture high-precision machines, and some of them can even be compared with foreign advanced high-precision machines, but there is still a gap with the top foreign high-precision machines. of.

Seeing this, Wang Bin was still a little depressed. In the world where Xu Zhenming and the others lived, that is, in the early 1990s, the country had already started to catch up with foreign technology. However, thirty years have passed, but the country is still in this respect. There is a certain gap. You must know that ultra-high-precision machine tools and materials science are not the mother of industry! It can definitely represent the industrial level of a country!

However, although he was a little depressed, he was not in a bad mood, because with him getting the technology mall system, this situation will definitely change. In the future, Tiangong Technology will definitely be able to produce the world's top machine tools. Of course, now Wang Bin All he has to do is to develop Tiangong technology first and raise the level of the technology mall, so that he can buy more advanced technology and more advanced products.
