Chapter 65 - Do It Yourself (1)
"I got on the News Simulcast." Fatty had gotten up early in the morning and bombed the other people in the dorm last night. When they heard this in the morning, they immediately covered their ears.
"Damn you, why are you so cocky if you don't sleep early in the morning?" Liu Yang searched for something to throw on the bed, but he could not find, so he could only scold: "You only have one arm on News Simulcast, you fat arm, go die!"
In the midst of all the protests, Fatty was kicked out of the dormitory. It was only seven o'clock and he already didn't want others to sleep well. Wasn't it his junior who still had to attend classes? Was there really a need?After finishing his breakfast, the fatty, who had calmed down, directly ran to the school factory to look for Elder Liu. They had said that they would reforge the old machine tool from Rhine in 1933, and now Guo Tailai was finally going to do it.
"Great." Elder Liu was also very happy. "Five years ago, I already had several tons of special steel stored outside. After being exposed to the wind and sun for five years, I should be able to see the light of day."It's easy to make a lathe, but it's not so easy to make a delicate lathe. This way, the only result would be that the accessories made would not be accurate or even deform. That was something that no matter how high the processing accuracy was, it would never be able to make up for, because the most important problem was the internal stress of the materials.
It begins to process when the internal stress is not fully released, and it is inevitable that it will deform afterwards.
There are many ways to release internal stresses in materials, such as heat treatment, artificial beat vibration, ultrasonic shock vibration, etc. But usually, the best way is to eliminate internal stresses by natural aging, which is to put it into natural condition. Of course, this method was the slowest.
There is a long period of time in the country to be unable to make real high precision machine tools, and sometimes has to do with the material. The pace of modern people is so fast that few people can settle down and spend years waiting for a circular axis or a guide rail to release its stress. Although heat treatment could quickly remove stress, the effect was not ideal. Low accuracy was fine, but high precision lathe s had extremely strict requirements. They did not have enough precision to create things. This was also one of the reasons.Five years of material, of course, that's for the best. Guo Tailai and Elder Liu did not care about the materials first, but rather took down the old lathe. To be honest, the most valuable part of the old lathe was its bed. The same reason was because of the internal stress. The old lathe's bed was always machine tool factory's favorite. Therefore, the bed had to be kept.
As for the other parts, they would have to be redone and replaced. Guo Tai Lai, Elder Liu, and the others were all veterans. Very soon, with the help of a few carpenters who came over to help, the old lathe was completely dismantled.There was no need to remap all the parts and components, and Guo Tailai did not intend to recreate a old lathe from decades ago. With this condition and the materials he had stored for five years, why not create an advanced one?
It was impossible to create an advanced five-axis processing center, even with Guo Tailai's craftsmanship, he couldn't do it with the chip and the control system. Therefore, Guo Tai Lai's plan was to use the old lathe's bed as the base to create a high precision mechanical lathe. Hmm, it's just a lathe. It's unlikely that it has any other functions.
There would be many high precision lathe in the future, so Guo Tailai chose one that was most suitable for this old lathe bed. Of course, the bed had to go through a series of processes. After all, it was an old model from decades ago, and some parts needed to be modified in order to fit the new type of lathe.
The electrical machines had to be re-selected, everything in the gearbox had to be re-designed, and the rest of the bearings, rails and other parts had to be the same. It was probably enough for Guo Tailai to work two or three months everyday. Get rid of the winter break and be busy until next April. He would be able to hold on for a little longer until June. At that time, he would have to busy himself with his graduation defense, then graduate and take a leave, waiting for the start of his postgraduate studies in September.
It's a good plan. Guo Tailai explained his plan to Elder Liu. How could Elder Liu not agree when he heard that Guo Tai Lai didn't want to create old lathe but wanted to create a high precision lathe of his own design? The better Guo Tailai behaved, the more respect he would have as his master.
The other parts were fine, but the pure machinery could be made by Guo Tailai himself, but not the electric motor. Besides processing, the electric motor had to be wound, so he had no other choice but to find a suitable electric motor on the market. He did not have much funding nor did Elder Liu have any good model suggestions. He could only look for Zhao Yanyan. Elder Liu went to apply for the money, while Guo Tai went to look for the electric motor.
"Motor?" Zhao Yanyan asked Guo Tai Lai what she wanted to do, and after getting the parameters that Guo Tai Lai needed, she did not refuse, "I will have the company help you check the models, but do you have any funds?This was the project that the department and the Professor Wang had agreed on, the additional fee must definitely be approved, and Zhao Yanyan could not directly help Guo Tai Lai raise the money, and Guo Tai Lai himself would not provide the money, so Zhao Yanyan had asked this question.
"Ask about the model and price first." Guo Tailai answered honestly, "Old Liu has already applied for the funds. I wonder how much he can apply for."
"Are you sure you want to design it yourself?" With regards to Guo Tai Lai's request to design a brand-new high precision lathe, after experiencing the high precision gyro, Zhao Yanyan had no doubts about Guo Tai Lai's design and assembling ability.
"Why not?" Guo Tai Lai was curious why Zhao Yanyan would ask such a question.
"If that's what you're going to do, you'd better go through the formal project approval process." Zhao Yanyan instructed: "You must first take out the design draft and have the experts review it once. Only after you have obtained the feasibility report can you then apply for the production budget and go through the procurement process.
"So complicated?" Guo Tailai was shocked. If he really had to go through this process, wouldn't that mean that even the yellow flowers would turn cold and he might not even be able to start work after graduation?
"That's why I'm curious!" Zhao Yanyan was really curious: "Didn't you plan to recreate all of the accessories and then assemble them? Why did you change your design again? ""I was planning on using this exercise to assemble the equipment." Guo Tailai was also helpless. "But didn't you make a high precision gyro last time? This exercise was useless. Rather than just making a new one, we might as well make a new one. "
"Then why don't you do it yourself?" Zhao Yanyan suddenly suggested, "This will be much simpler."
