According to the above requirements of the data, the weight of the last machine tool alone reached about 15 tons and the length reached more than 10 meters. There is no doubt that the data of this machine tool is definitely a heavy machine tool. Wang Bin can be sure that if this machine tool is built, its total weight will definitely exceed 30 tons.

    Soon after reading these data, Wang Bin said to Xu Zhenming, "Mr. Xu, the price of small and medium-sized machine tool beds is priced at 20 energy yuan per ton, while for large beds, it is temporarily priced at 30 energy yuan per ton! I don''t know whether Mr. Xu can accept it?"

    "Yes!" Xu Zhenming said immediately after Wang Bin finished.

    Xu Zhenming doesn''t think the price mentioned by Wang Bin is very high. This is the machine bed of high-precision machine! There are high requirements for accuracy, so processing can not be completed in a moment and a half.

    Of course, the price is actually not cheap. Take the bed of a small machine tool for example. The bed of a small machine tool weighs about 1.1 tons, that is, 22 energy coins. It doesn''t seem to be a lot. If you change it into real money, the price of a small machine tool bed is equivalent to 22 million,

    Not to mention the price of medium-sized machine tools and heavy-duty machine tools. If calculated according to the real money, the price of medium-sized machine tools has reached 60 million or 70 million, and the price of heavy-duty machine tools has reached tens of millions, not to mention the real money. The energy currency of science and technology mall is even more rare.

    "As for the central axis, the central axis of small machine tools is 5 energy coins! For heavy machine tools, the temporary price is 15 energy coins, and the central axis of large machine tools is 30 energy coins. Mr. Xu doesn''t know if this is OK?" Wang Bin asked again.

    "OK, just follow the price you said," said Xu Zhenming.

    After that, he thought about it, and then said to Wang Bin: "Twenty sets of small machine tool bed and central shaft, five sets of medium machine tool bed and central shaft, and two sets of large machine tools first! After all, compared with small machine tools, the heavy machine tool weighs only fifteen or six tons, so two sets are my limit. If there are more, I can''t bear it."

    Then Wang Bin and Xu Zhenming talked for a while, and Xu Zhenming withdrew from Wang Bin''s shop.

    Wang Bin saw Xu Zhenming walking out of his shop. He was not ready to quit the shop, but said to the system in his mind: "system! I want to buy bearing steel technology. As for which world bearing steel technology to buy?"

    When it comes to this, Wang Bin thought that compared with the red police and Empire, he thinks the material technology of kanxing world is more reliable. After all, anyway, kanxing world is a world in which the whole people develop aerospace science and technology, so their bearing steel must also be the bearing steel of aerospace aircraft. Therefore, Wang Bin believes that kanxing''s technology is more reliable at the same price , it will certainly be better than other bearing steel technologies in the world.

    What''s more, Wang Bin already has aviation glass technology in his hands, and also has a complete set of kanxing Aerospace glass technology in his mind. Therefore, compared with other world technologies, Wang Bin feels that he should understand kanxing world technology more easily.

    "It''s better to choose the bearing steel smelting technology of kanxing world!"

    When Wang Bin finished in his mind, the system in his mind immediately listed the list of kanxing bearing steel smelting technology.

    From the perspective of kanxing bearing steel smelting technology in my mind, kanxing''s bearing steel is divided into five generations, that is, one to five generations of bearing steel technology, and there is not only one bearing steel smelting technology, including high-temperature and high-pressure high-speed bearing steel technology for bearings used in engines, high-performance bearing steel technology used in various motors of aircraft, etc., but now Wang Bin can''t buy it at all Buy five generations of bearing steel technology. With these energy coins in his hand, he can only buy the first and second generations of bearing steel technology at most.

    Of course, if the same generation technology, for Wang Bin, the most desired bearing steel technology is naturally the high-temperature and high-pressure high-speed bearing steel technology used by aircraft engines.

    After all, even fools know that compared with other bearing steels, the bearing steel technology of engine is the best. After all, this is the bearing steel technology of jet engine!

    You should know that when the jet engine is running, the bearings inside not only bear the internal high temperature and high pressure of thousands of degrees, but also the internal speed of the jet engine is very terrible, and ordinary materials can''t bear it at all.

    However, compared with other bearing steel technologies, engine bearing steel technology is also the most expensive. Take the energy currency in Wang Bin''s hand. If you buy other bearing steel technologies, even if you buy the second generation technology, it is only 600 or 700 energy coins, so it is more than enough.

    However, if you buy the bearing steel technology of engine bearing, the first generation of engine bearing steel technology needs 850 energy coins, and the energy coins in his hand are just about the same.

    However, Wang Bin is not sure which technology is better between the second generation of kanxing''s other bearing steel technology and kanxing''s first generation engine bearing steel technology.

    After thinking about it, Wang Bin still gritted his teeth and directly purchased the first generation of engine bearing steel technology. After all, it is the engine bearing steel technology of engine jet aircraft, and its performance will never be worse.

    Moreover, as a world of national aerospace, kanxing''s engine technology is definitely not comparable to that of Wang Bin''s world. Even the first generation engine bearing steel technology requires a stable operation time of at least 5000 hours, that is, each bearing must be able to operate safely for more than 5000 hours in the aircraft engine, Therefore, the bearing steel technology is absolutely very advanced, although it is only the first generation technology of kanxing.

    "The system buys kanxing''s first generation jet engine bearing steel technology!" Wang Bin said to the system in his mind!

    "OK!" said the system coldly.

    With the completion of the system, nine large amounts of energy coins directly disappeared in Wang Bin''s counter, and the drawer of the whole counter immediately became empty, leaving less than 50 energy coins.

    At the same time, Wang Bin felt that his head began to dizzy, but after a while, it was all right, but Wang Bin could clearly feel that he had a lot of knowledge in his mind, as well as the formula and smelting process of special steel.

    Then Wang Bin began to carefully browse the smelting formula and process of this bearing steel in his mind and found that this bearing steel was brought into the real world. Although it did not belong to black technology like the previous special glass, it was already the world''s top bearing steel. Most importantly, the smelting cost of this bearing steel was not high, Except for some strategic rare metals, other costs are only equivalent to the smelting price of slightly better bearing steel.

    However, it''s normal for him to think about it. After all, this bearing steel has long been an obsolete technology in kanxing, and the cost will not be high there.
