In the office, Wang Bin first looked carefully at the drawings of these business orders received from the official trading company.


    He found that the most difficult part of the order was not the parts on the aeroengine, but a spindle that he didn''t know what to do. The length of the spindle reached more than 13 meters and the maximum diameter was about two meters. According to Wang Bin''s judgment, this may be the spindle used by a large ship.


    One end of the main shaft is OK, but it is only a thread, but the precision requirements are a little high, but the other end is different. It not only has many gear like designs, but also has grooves and holes in many places. These holes are large and small, and even some holes are not straight, but other angles. It needs to be hollow in some places. In short, The machining of this spindle is very difficult.


    However, fortunately, the steel required by this spindle is not a super special steel with high performance requirements. It only needs ordinary special steel.


    This greatly relieved Wang Bin, but even with ordinary special steel, it is not easy to make such a big guy.


    After reading for a while, Wang Bin came to the precision machining workshop with the drawings, found master Zhou, the person in charge of the precision machining workshop, and showed him these drawings.


    Master Zhou took the drawing in Wang Bin''s hand, read it for a while, and then said to Wang Bin, "Mr. Wang, where are you? You''ve taken such a big guy, good guy. Not only in terms of length and size, you''ve far exceeded the limit that ordinary large-scale machine tools can process.


    Even in terms of precision, there are very high requirements. I bet that no enterprise in our county, even in the city, can produce this big guy. Of course, except us.


    However, this big guy, although the processing is very difficult, it can still be processed with the current ability of Tiangong technology, but the processing time is also very long, and it will take at least half a month to complete. "


    After listening to master Zhou''s words, Wang Bin breathed a sigh of relief. After all, if he can''t process it, he can only pull down his face and go to the city to push off the order with the government. However, in doing so, although the government won''t say anything about their Tiangong Technology, it will definitely leave an unreliable impression, This will definitely have a great impact on their future business of Tiangong technology.


    So Wang Bin said to master Zhou, "that''s good. I''ll give you the task. If you have any difficulties, you can come to me at any time.


    As for the delivery time of this order, the official has no hard and fast rules, but they hope we''d better finish it within half a month! "


    After Wang Bin received the order from the city, Tiangong technology returned to normal, and all kinds of business and R & D projects were carried out in an orderly manner. It was not until half a month later that there were cheers in the mechanical experiment workshop that Wang Bin''s experiment was disrupted again, Let him go out of his laboratory again and come to the mechanical experiment workshop.


    "Mr. Wang! We have completed the design and production of the special copper alloy production line you want!"


    When Wang Bin heard their cheers and came to their mechanical test workshop, Yu Pingping couldn''t wait to come up and said happily to Wang Bin.


    "Good! Have you tested it? How is the operation of the production line?" Wang Bin asked Pingping with a smile.


    "Mr. Wang, the production line has had a trial run, and the production process is very smooth without any problems!" Yu Pingping replied.


    "That''s good! But don''t be happy too early. You''ve already conducted a trial run on this production line, but it''s just empty running, so you can''t really determine the situation of this production line.


    I think so! Let''s have a trial production of this production line and see the situation of the production line! "Wang Bin said.


    "Good!" Yu Pingping and others said.


    After that, Wang Bin took Yu Pingping and others out of the experimental workshop, came to the raw material warehouse, and directed the workers to move some raw materials to the experimental workshop for testing the production line.


    Soon, with the cooperation of the workers and masters, the raw materials they needed were successfully obtained to the experimental workshop, put into the production line and start the production line.


    Yu Pingping and others also consciously entered the operator positions on the production line and opened the production line.


    Soon, the first batch of copper based room temperature superconducting material solution produced by the production line slowly set aside the solution outlet of the production line and entered the already prepared mold under the attention of Wang Bin and others.


    Because this is only a small production line, and this time it is only trial production, there are not many copper-based room temperature superconducting materials produced this time, only half a ton.


    Soon, all the solution in the production line has been poured into the mold.


    With the efforts of the workers and masters, these molds were cooled in the special coolant that Wang Bin had already prepared.


    Ten minutes later, these molds were salvaged from these special coolant in the eyes of everyone.


    When these molds were salvaged and placed on a pallet of goods, Wang Bin immediately stepped forward to check these materials.


    When he came to a mold, Wang Bin first looked at the color of these materials. After all, this is the easiest place to judge. If the color is wrong, it naturally means that the copper based room temperature superconducting material produced this time has failed.


    To Wang Bin''s relief, there is nothing wrong with the color of these materials produced this time, just like what he produced in the laboratory!


    Then Wang Bin opened one of the molds, took out a piece of material from it, weighed the weight, and then knocked again. There was nothing wrong with listening to its voice. Wang Bin also put a lot down in his heart, because according to his observation, the copper based room temperature superconducting material produced this time is likely to have become.


    Of course, this is only the result of others'' judgment. Whether this production line is really successful in the first trial production depends on the test results of professional instruments,


    Therefore, Wang Bin immediately took a piece of material to his laboratory and began to test the material.


    Before long, Wang Bin finished the analysis of this material and obtained the results. That is, the performance indexes of these copper based room temperature superconducting materials produced this time have met the required data, that is, the production line developed by Yu Pingping can definitely produce copper based room temperature superconducting materials this time.


    So Wang Bin got up, went back to the machinery R & D experimental workshop and told Yu Pingping the news.
