Chapter 11 - exoskeleton seat (1)
Two crankshaft s, the biggest error was not more than 2 microns. Both were within the tolerance range of 5 microns, and their surface finish had met the requirements of the company. Even the Roundness and Coaxial Degree that Da Xiyizhen cared the most about did not exceed 1 μm. It was precise to the extreme.
This kind of processing technique was obviously not something that could be done by human hands. Even if it was possible to do it using manual labor, according to the time in Wan Manager, after digging back and forth for a day, it would only take a day at most.
China has high precision numerical control machine tool? This was a huge matter!His heart was already in turmoil, but Da Xiyizhen"s face did not change at all, he stood up and congratulated the Wan Manager: "Congratulations! Wansan, we can begin negotiations on the transfer of technology for that engine. "
This kind of negotiation was not something that could be completed in a day or two. Wan Manager, accompanied by Da Xiyizhen, left the Suzaku Company and prepared to immediately form a negotiating team to start the negotiations.Da Xiyizhen, who had sent off the Wan Manager, immediately called a meeting to study the processing techniques of the two crankshaft and the words he had recorded from the Wan Manager. Of course, the main point was to deduce the current situation of the Chinese high precision numerical control machine tool from this.
"Don"t tell the little devil a single word without a hundred thousand yuan." After returning to the hotel, Wan Manager instructed his secretary directly.The capable secretary nodded, but in her heart, she rolled her eyes. He had only paid a total of 50,000 for the processing fees, yet he sold it for 100,000 just like that. As expected, he was a cunning businessman.
However, Wan Manager"s next sentence made the little secretary smile brightly.
"No matter how much you can get, it"ll count as your travel allowance. The company won"t receive any other benefits." Wan Manager casually said, "Have fun."
The company"s travel allowance was only a small amount of money, but 100,000 yuan was more than a dozen times more than that. The secretary had decided to go to Tokyo from Jingang County to buy the long-awaited bag and makeup.
Guo Tailai didn"t know that he had already earned a huge sum of money. He lived a comfortable life in school and enjoyed a wonderful fifth year of life with his roommates.
Even his closest roommate couldn"t tell that Guo Tailai"s gla.s.ses were different from before the holidays. Now he was just wearing the same frame, but inside he was wearing a pair of flat gla.s.ses, completely without any count.
Liu Yang and Guo Tailai were best friends, he admired Fatty for being able to lose more than 20 jin of weight in this one month"s vacation.
However, Liu Yang was a specially recruited student in sports, and the school team specialized in volleyball, so he could just barely be counted as half an expert in fitness. Since the start of school, he didn"t have time to bother with it. He took advantage of Guo Tai"s early return to talk about losing weight and losing it too quickly to avoid damaging his body.
Fatty was naturally a kind person who would follow the flow. Under normal circ.u.mstances, it was not a good choice for him to quickly lose weight. Thus, he had already made a plan to reduce his weight at the rate of four to five catties per month.
Even if there was a nan.o.bot, Guo Tailai firmly believed that the body belonged to him. The night pa.s.sed quickly in the midst of laughing and laughing.
The next morning, Guo Tailai was still early in the morning. After breakfast, he went straight to the school"s factory locksmith"s workshop.
He had already done half of the graduation design sample. Yesterday, he was delayed by the task Elder Liu arranged for him. Today, he would continue to complete the subsequent part.Speaking of which, the tools in Elder Liu"s Workroom were really exquisite. Guo Tailai felt itchy just thinking about it, so he used these tools to make them today. The only flaw was that the material was only ordinary steel, not better t.i.tanium alloy.
After arriving at the workshop, Guo Tailai went straight to Elder Liu"s Workroom. Even though Elder Liu"s Workroom was locked, and the key was in Elder Liu"s hands. However, to a fatty who was extremely proficient in locksmith work and had two eyes that could reach 1 micron accuracy, was that kind of ordinary padlock key a problem?
Obviously not. Fatty could easily find a metal file and produce an identical key. It did not even take ten minutes. Seeing him arrogantly opening the room with the key, the other people did not care about him. In any case, Elder Liu had already agreed to let him use the Workroom, and many people knew that.
He first appraised every tool before starting his own work. Before, old lathe from 1933 could use the hydraulic cylinder and hydraulic piston they got from the car. They did not need to adjust it too much, they only needed to do the remaining parts.
Not long after he started working, Elder Liu walked in with two fitness b.a.l.l.s in his hands.
Mr. Liu was not surprised that Guo Tailai could enter without a key. A genius who didn"t even need to use measuring tool to process 5 microns of precision, asking him to use the key to open the door once before using such a simple lock to block the door was simply a joke.Guo Tailai greeted him politely. It was only this morning that Guo Tailai found out Elder Liu"s ident.i.ty and his position in the factory. Besides, he was old enough to devote his life to the country, which was enough for Guo Tailai to respect.
"Fatty, what do you think about that crankshaft yesterday?" Elder Liu sat in the only chair of the Workroom and asked Guo Tailai with a smile.
"Normal four-cylinder engine crankshaft." Guo Tailai stood in front of the workbench, gesturing with the saw while answering casually. "But the designer is trash. If I were his boss, I"d fire him immediately."
"What do you mean?" Elder Liu asked Guo Tailai with a smile on his face.
"Engine crankshaft, you need the same axis to be no more than 5 μm, normal. "It"s normal for the roundness and cylinder to be high." Guo Tailai kept his eyes on the workpiece as he replied, "But your other size requirements are also 5 microns. Aren"t you just looking for something to play with?""The normal expansion coefficient of steel is 10 times or 10 times negative six times per degree centigrade. A meter long workpiece would have a length change of over 10 microns per degree Celsius." Guo Tai Lai continued to explain without raising his head: "Your accuracy is so high, but you don"t mark the temperature requirements. Isn"t that a bit excessive?" Furthermore, the working temperature of the crankshaft is at least tens or even hundreds of times higher than the normal temperature. The size of the crankshaft has already expanded by more than a few dozen or even hundreds of microns, not to mention the disturbance and deformation caused under such complicated conditions, what"s the point of needing 5 microns? "
"So, if the designer is not trash, then it is an intentional increase in processing costs and difficulty, as well as an additional expense." Guo Tailai cut the workpiece in his hand. Then he looked up at Elder Liu and said, "Old man, do you want to fire this designer?"
"If I were to guess, I"d be fired too." Elder Liu smiled happily. Looking at the fatty"s shapeless workpiece, he pointed at the piece on his hand with interest. "What are you trying to do?"
"My graduation design." Guo Tai Lai answered quickly. "exoskeleton seat."
