Master Zhang nodded helplessly and didn''t speak, because he didn''t have any hope for Master Zhang''s material laboratory.


    After all, the tool he uses now is a very advanced tool for superhard metal processing. According to the data of this tool steel, the hardness of this tool has reached the level of 105. Even for this tool steel, the price Wang Bin bought from Tony is as high as ten energy coins a ton, That is, one ton relative to the price of more than ten million.


    However, even this kind of tool has exceeded the hardness of diamond. Although it can process this special steel, it can not process this metal smoothly.


    From here we can see how hard the special steel developed by Professor Zhang is.


    Therefore, in order to improve the processing speed, accuracy and efficiency, Wang Bin can only use tools with stronger hardness, that is, the tools in Wang Bin''s No. 1 warehouse.


    Of course, like the tools Wang Bin is using now, these tools in the No. 1 tool warehouse are also purchased by Wang Bin from Tony.


    However, in terms of price, the price of these tools in No. 1 tool warehouse is much higher. The price of only one tool varies from five to ten energy coins according to the type and quality of tools. If it is changed into money, basically the price of each tool is more than five million, and some are even more than ten million.


    Therefore, in general, Wang Bin and Tiangong technology will not use this kind of tool. After all, they can''t buy it with money, but can only use energy currency.


    At the same time, although they don''t know much about the price of these tools, whether it''s master Zhou or professor poke in the engine laboratory, when they know the performance of these tools, they naturally know that the price of these tools is absolutely not cheap. Otherwise, as Tiangong technology without money, It will not establish a warehouse for this kind of tool.


    Wang Bin also knows that although he can buy this kind of cutting tool with super performance from the customers of the science and technology mall, if Tiangong technology can''t produce it, Wang Bin can''t put his heart down.


    After all, both Tony''s universe and Lao Huang''s universe seem calm now, but I know that such calm will not last long for the human civilization in Tony and Lao Huang''s universe, and the alien civilization has long been staring at the earth.


    Therefore, once these cosmic alien civilizations began to invade Lao Huang and Tony''s universe, it would be difficult for him to get these things from Tony and Lao Huang again.


    Therefore, Wang Bin must rely on himself to make corresponding products.


    At the same time, he is ready to go to the technology mall in the evening to see if his customers have corresponding technology sales. At the same time, he is also ready to see whether there is such tool steel technology sales in the system. If so, it would be the best.


    After chatting with master Zhou for a while, Wang Bin came to the other side of the precision machining workshop. Different from master Zhou, what is produced here is not high-pressure turbine blades, but fan blades of large bypass ratio engine.


    And the materials used for these blades are no longer super special steel developed by Professor Zhang, but made of special glass.


    The machine tool for processing these fan blades is not a machine tool developed by Yu Pingping and others, but a quasi ultra-high precision CNC machine tool produced by a well-known domestic machine tool manufacturer, and this machine tool is also a vertical machining center.


    Although the master who operates this machine tool is much younger in age, and master Zhou is probably less than 40, he is no worse than master Zhou in technology. Otherwise, he will not be arranged in this workshop.


    "Mr. Wang! These fan blades made of special glass are really beautiful. I bet that the appearance produced by the engine will definitely explode all products of the same type," said the middle-aged master.


    "Master Qu, I absolutely believe in this. After all, the tg001 turbojet engine we developed before has a very beautiful appearance.


    At the same time, I also believe that the engine we have developed will definitely have very strong performance in terms of quality, performance, thrust and so on, and can definitely surpass the same type of products, "Wang Bin said.


    With that, Wang Bin picked up a turbofan blade and looked at it. Compared with the turbine blade, the turbofan blade is undoubtedly much larger, of which the widest place is more than ten centimeters, and the length of the whole fan blade is 60 or 70 centimeters.


    And because these blades are made of special glass, coupled with the transparency of this special glass, these blades look very beautiful under the light of the workshop.


    At the same time, although it seems that the size of these blades is relatively large, because the center of these blades is hollow, and the glass itself is an aviation glass, these fan blades are not heavy, and even have the same quality as the blades of general turbofan aeroengines.


    In the following days, Wang Bin, Professor Cha and others have been busy with the turbofan engine. Of course, Wang Bin has not been slack in other aspects. For example, Wang Bin has been paying attention to the production of tg001 turbojet engine which has been successfully developed before.


    In addition, because the electric helicopter engine has been developed and has been tested, Wang Bin is also very concerned about this matter.


    Of course, because the batteries of Tiangong technology are only the first and second generation, the maximum power of the electric engine developed now is only 100 kW and 500 kW.


    At the same time, for higher power electric engines, Wang Bin''s laboratory has also been developing them in advance. After all, as long as Tiangong technology successfully develops the third generation superconducting battery, the maximum power output and maximum output voltage of the battery will be completely solved. At that time, even for high-power motors, the demand for power can be solved.


    At this time, the two kinds of electric engines developed by Tiangong Technology Institute have started test run. Because they are electric engines, Wang Bin did not continue to run slowly from a few minutes to a few hours, and then to more than ten hours, like fuel engines
