Chaoshen Technology Trading Mall

In the end, Donald spent fifteen energy coins and ordered a ton of special heat-resistant glass from Wang Bin, ranging from 0.5 mm to 12 mm. In comparison, he bought more than 5 mm. More often, at the same time, according to the agreement between the two of them, Wang Bin must complete the transaction for this order within three days.

When Donald walked out of Wang Bin’s shop, Wang Bin was also ready to launch the Science and Technology Mall. After all, their Tiangong Technology’s production capacity is only this small, and they have to supply 969 Group and Qin's Industry, so even if they keep some of them every day, It's just over a ton at most.

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

But when Wang Bin was about to quit the Technology Mall, he suddenly thought that the system rewarded Wang Bin's special glass technology during the previous novice mission. Does that mean that he can still buy Kanxing and Red Alert from the system? technology.

So he immediately asked the system: "System! Can I still buy technology in Kanxing, Red Alert and other worlds? Do I need to buy it from the Science and Technology Mall stores in Kanxing, Red Alert, and Empire, or directly from the system? ?"

"Dear host, because Kanxing, Red Alert, and Empire are all small universes, these worlds do not have a science and technology mall host, and there are no shops in these worlds in the natural science and technology mall, but there are some people in their world who can come to science and 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 official of the science and technology mall by these people, especially the material technology, so if the host If you want to continue to buy the technologies of these worlds, you can buy 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 technologies of these three worlds are the most suitable, so he was a little worried before. After completion, it is no longer possible to purchase technology from Kanxing, Red Alert and Empire.

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

Although Wang Bin had already obtained special high-temperature resistance technology from the system before, Wang Bin did not spend any energy coins on this technology, but was a reward for the newbie of the system.

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

"Canstar Aerospace Primary Re-entry Atmosphere 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......

....

....

Purchase price, 15000 energy coins.

Kanxing primary aircraft skin material technology...16000 energy coins.

Kanxing bearing steel smelting technology:...110000 energy coins.

Kanxing tire technology...18000 energy coins.

....

Wang Bin looked at Kan Xing's material technology for a while, and he found that among Kan Xing's material technology, the cheapest one cost 16,000 energy coins, and that was the return cabin skin technology.It is also the most advanced skinning technology for the return cabin.

And the price of the high-level material technology in Kanxing is even higher. It is not what Wang Bin can buy now. In addition, the material technology in the Red Alert and Empire is much cheaper, but currently the earth does not have or has no performance. The prices of those materials that reach the level of these materials are basically above 12,000 energy coins, while the outdated technologies are much better, basically only a few hundred energy coins, and even a few energy coins.

Of course, for the current earth, Wang Bin still looks down on the outdated or already possessed technology.

After watching for a while, Wang Bin withdrew from the system. After all, he didn'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.

Subsequently, Wang Bin withdrew from the Technology Mall and returned to reality.

When he returned to reality, he found that time had only passed by one minute. You must know that he was in the science and technology mall, but he stayed 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 reality and the time in the science and technology mall are synchronized, then 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 was not big. Many of the things in it seemed to be old and old-fashioned. It's not up to this era.

In the office, Wang Bin stood at the window and looked out the window to the factory area. At this time, it was when Tiangong Technology was at work, so he could clearly see that many of their factory workers were entering the factory from the outside and punched in. workshop.

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

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

The domestic grade accuracy is divided into 7 grades: P1, P2, P3, P4, P5, P7, P10. Among them, the p1 grade has the highest precision. The stroke variation within any 300mm stroke is 4 microns, and the level is 6 microns. , Level 3 is 9 microns, and level 5 is 23 microns.

Of course, Wang Bin can’t afford screw production lines of p1 and p2 levels at all now. After all, screw production equipment of p1 and p2 levels can start at least tens of millions. At the same time, after they are processed, a series of For the follow-up processing, in order to ensure the accuracy, general processing equipment does not work at all. It must be done with top international equipment, and the price of these equipment is 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, they will not use it. So Wang Bin plans 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 recent years, due to technological breakthroughs, it has been possible to manufacture high-precision machines, and some 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's heart is still a little depressed. The world Xu Zhenming and the others live in, that is, in the early 1990s, China has already begun to catch up with foreign technology. However, 30 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 are the mother of industry!It can definitely represent the industrial level of a country!

Although he was a little depressed in his heart, he was uncomfortable. This situation would definitely change as he got the technology mall system. In the future, Tiangong Technology could definitely produce the world's top machine tools. What needs to be done is to develop Tiangong Technology first and raise the level of the Technology Mall, so that he can purchase more advanced technologies and products.
