Chongzhen Emperor Zhu Youzhen suddenly thought, it's a pity that Professor Gu Luotu can't go to Daming, otherwise he will be arrested directly, or in two or three years, Daming will dominate the world!

But it's impossible, he can't take people with him!

"Spindle systemThe spindle system has always been the most important part of the machining accuracy of machine tools. It can be said that what scheme is used in the spindle system of this machine tool, basically its machining accuracy is determined. The spindle system generally includes: spindle, bearing (the spindle is supported on the machine tool by it), gears, claw plates, etc. As mentioned earlier, the lateral force from the gearbox guides the spindle bending (of course, this bending is very small), in fact, there is another point that was not mentioned at the time, the bearing is very critical in the eccentricity of the operation of this bending guide, and there is also the force between the tool and the machined parts superimposed on it, plus the complexity of the bearing itself, simplifying the model a lot, but the precision model is very, very difficult, and the breakthrough of ultra-high precision machine tools is also more here. However, in the design of traditional ordinary machine tools, this piece is actually relatively simple, and of course, the accuracy is ordinary. This fact speaks volumes about the fact that simple things are actually the hardest. "Professor Gu Luotu is giving a specific analysis of why he deviated so much just now to Jian Xun Lou.

Chongzhen Emperor Zhu Youzhen nodded, "In this system, bearings are very critical things, ordinary bearings have been seen by everyone, but precision bearings may not be understood." Relevant people must know the classification of bearings, high-speed and high-precision bearings are difficult to do, once there were Russian dreadnoughts because the bearings of the muzzle seat could not be manufactured and stayed on the slipway during the First World War. Bearings are quite important in modern society. ”

Professor Gu Luotu was a little amused, and looked at Jian Xun Lou with great appreciation, as if he had found a little bosom friend. I feel very interested in talking to Jian Xun Lou. "Not only are you smart and willing to learn. What about some historical knowledge? The bearings you just mentioned are one aspect, and the tooling system! The tool is also very important in the machine tool, after the tool is deformed after being stressed, is the tool tip still facing the center of rotation of the machined part? The influence of tool chatter on machining accuracy, the study of tool wear and its impact on machining accuracy, and what will happen to tools of different materials. The movement of the tooling system is carried out by means of a spindle. If the precision of the screw is not high, the movement will not be stable, and the accuracy will be poor. This is especially taboo when the knife is fed both horizontally and vertically at the same time. High-precision screw rod is difficult to do, how high the requirements are, for example, after processing, it should be hung up straight to prevent deformation, and the requirements for natural installation are also quite high. ”

Listening to Professor Gu Luotu say this, Chongzhen Emperor Zhu Youzhen suddenly felt a little sad, even if he can master these techniques, but if he can really be in Daming. He independently produced the tools he brought from the modern age, and then he had to produce higher-level tools. You have to study for at least ten or eight years, right? When will it be ready for mass production?

Professor Gu Luotu saw that Yan Ting and Jian Xunlou seemed to be a little tired, and smiled slightly, "I have said enough today, any discipline, if you really want to sink your heart, it will take more than ten years, things in the world are not achieved overnight, practice slowly, don't be in a hurry, and experience it with more heart, Jian Xunlou, I am very optimistic about you." Go for it. ”

Chongzhen Emperor Zhu Youzhen nodded, very grateful, but ten or eight years, how could he wait to come? But after thinking about it, he can't get small things, but some things that don't require very high precision, but have a great effect, he still has a chance to get them! Can't make guns, can't you make cannons? It is not possible to build an airplane, it is not possible to build an early engine, first build a large ship, first use an old-fashioned steam engine, supplemented by an internal combustion engine and a steam turbine! Don't be too pessimistic!

Thinking of this, Chongzhen Emperor Zhu Youzhen smiled slightly, looking at the changes on the face of Jian Xunlou, after Daddy left, Yan Ting thought that Jian Xunlou was thinking about the operation just now and was distracted, and sighed softly.

Chongzhen Emperor Zhu Youzhen came back to his senses and smiled slightly, "Your daddy is indeed very powerful!" I don't know when I'll get to that level. ”

Yan Ting pursed her lips slightly, revealing a very good-looking smile, "You are not suitable for this, people who are too persistent in doing things, in fact, they are very suitable for high scientific research, but it is easy to become a fool, a nerd?" ”

Of course Chongzhen Emperor Zhu Youzhen is not worried about this problem, with his life experience, with his life experience, of course he will not say this to Yan Ting, shrugged his shoulders, "Thank you for your concern, I won't, I have many other hobbies, the gear that your father made just now, can you take it back for me as a reference?" ”

Yan Ting nodded, "Yes, but are you going back?" ”

Emperor Chongzhen Zhu Youzhen was surprised, "It's a little late, I heard your father say, it's just learning things, practicing here and going back to practice by myself with me, in fact, it's all the same." ”

Yan Ting was a little disappointed, "Oh, okay, but if you like to practice here, it's okay, and if you don't understand, you can always ask me daddy, isn't it better?" ”

Chongzhen Emperor Zhu Youzhen shook his head sincerely, and bowed politely to Yan Ting, "Thank you and your father, if this is the case again, I will be embarrassed, and besides, I can still come tomorrow?" ”

Yan Ting smiled slightly, "That's right, but I seem to have heard Wen Chengtai say that you sleep two or three hours a day, and you have to do seven or eight jobs alone, is this true?" Don't be so desperate, next month, we're going to rehearse a play for the start of school, will you participate? ”

Chongzhen Emperor Zhu Youzhen didn't want to go, "No, I'm not very interested in these, thank you, goodbye." ”

Yan Ting is very unconvinced, there is no reason, is this Xunlou a fool? Where is there a job that boys are so obsessed with? She was thinking that she had to let this 'wood' open.

Chongzhen Emperor Zhu You checked out Professor Gu Luotu's home, and he kept looking at that gear, already fascinated!

Wen Chengtai smiled, "Brother Zhen, or am I driving?" Being an assistant for you is also hard and comfortable, in fact, it is just to drive for you. Don't you want to have a fun? My sister asked me to ask you to come to my house for dinner? ”

Chongzhen Emperor Zhu Youzhen snorted, raised his head, and said with a smile, "No, Wen Dailin often asks us to go to dinner, isn't it like that, and it's not a serious thing, besides, if we want to go to your house for dinner, we can go at any time?" (To be continued......)
