Chapter 6 Exoskeleton Seat On
The maximum error of the two crankshafts is only 2 microns, all within the tolerance range he required is plus or minus 5 microns, and the surface finish meets the requirements of the company's processing. Even the roundness, cylindricality and coaxiality that Daxi Ichima is most concerned about, does not exceed 1 micron, and it is simply extremely accurate.
Such a processing technology is obviously not something that can be done manually. Even if it takes time to do it, according to Manager Wan’s time, it only takes one day to complete it in at most. Except for high-precision CNC machine tools, there is no other possibility.
China has high-precision CNC machine tools? This is a big deal!
My heart was already stormy, but Daxi Yizhen's face was still silent. She stood up and congratulated Manager Wan: "Congratulations! Wansang, we can start negotiations on the technology transfer of that engine."
Such negotiations are not a matter of one or two days. Manager Wan, accompanied by Ichimashi Osaki, left Suzuki Company and prepared to form his own negotiation team immediately to start the negotiations.
Daxi Yizhen, who sent Manager Wan away, immediately convened a meeting to study the processing technology of the two crankshafts and the words of Manager Wan he recorded. Of course, the focus is on the current situation of China's high-precision CNC machine tools that were inferred from this.
"If there is no 100,000 yuan, don't tell the Japanese a word." After returning to the hotel, Manager Wan directly reminded his secretary.
The capable female secretary nodded, but rolled her eyes in her heart. The total processing fee was only 50,000 yuan, and one news was about to be sold for 100,000 yuan. It was indeed a profitable businessman.
However, Manager Wan's next sentence made the little secretary smile.
"How much can I get is all calculated as your business trip subsidy this time, and the company will not give additional subsidies." Manager Wan said casually: "Have fun."
The company's business trip subsidy is only how much, and the 100,000 yuan can exceed several times or ten times. The secretary has decided to go to Tokyo from Shizuoka Prefecture to buy the bag and cosmetics that had long been optimistic about.
Guo Tailai didn't know that he had already had a huge income, and lived a very comfortable school life in a daze, and enjoyed a wonderful life in his Big Five with his roommates.
Even the closest roommate did not see that Guo Tailai's glasses were different from those before the holiday. Now he was just wearing the same frame, but there was a pair of flat glasses inside, with no degree at all.
Liu Yang and Guo Tailai are best friends. He admires the fat man for losing more than 20 kilograms during a month's holiday.
However, Liu Yang is a sports special enrollment student. The school team is professionally a second-class volleyball passer, and is barely considered half an expert in exercise and fitness. She has not been at work these days since the beginning of school. She took advantage of Guo Tai’s early arrival and then found an opportunity to tell Guo Tai about the advice of not losing weight too quickly to avoid damage to her body.
Of course, fat people are good at following the flow. Under normal circumstances, it is not a good choice to lose weight quickly, so he has made a plan to lose weight at a rate of about four or five pounds per month.
Even with nanorobots, Guo Tailai firmly believes that his body is his own and he cannot overdraw his energy at will. He laughed and happier, and he quickly spent the night.
The next morning, Guo Tailai got up early in the morning, and after breakfast, he went straight to the fitter workshop of the school-run factory.
The graduation design sample has been made halfway, and I was delayed by the job arranged by Mr. Liu yesterday. Today I will continue to complete the subsequent part.
Having said that, the tools in Mr. Liu's workshop are really exquisite. Thinking about it, Guo Tailai was itchy, so I used these tools to create them today. The only drawback is that the material is just ordinary steel, not better titanium alloy.
When he arrived at the workshop, Guo Tailai went straight to Mr. Liu's workshop. Although Mr. Liu's workshop was locked and the key was in Mr. Liu's hands. However, for a fat man who can achieve 1 micron accuracy by eye measurement and is proficient in fitter work, is that ordinary padlock key a problem?
Obviously not. The fat man could find a piece of iron piece to file out an exact same key, which took him not even ten minutes to exceed. Seeing him swaggeringly fitting the key to open the room, others ignored him. Anyway, Mr. Liu had agreed to him to use this workshop, and many people knew about it.
After appreciating each tool, Guo Tailai started his own work. The hydraulic cylinder and hydraulic pistons that came out of the old lathe in 1933 were completely used, and there was no need for too much adjustment. Now, just do the rest.
Not long after he started, Mr. Liu walked in with two fitness balls again.
Mr. Liu was not surprised that Guo Tailai could come in without a key. A genius who did not need to use measurement tools to process 5 microns of precision, letting him open the door with the key once and rely on such a simple lock to block it was a joke.
Guo Tailai greeted him in a regular manner. This morning, Guo Tailai only learned about Mr. Liu's identity and his status in the factory. Moreover, at that age, he devoted his life to the country, which was enough for Guo Tailai to respect him.
"Fatty, what do you think of the crankshaft yesterday?" Mr. Liu sat on the only chair in the workshop before asking Guo Tailai with a smile.
"Ordinary four-cylinder engine crankshaft." Guo Tailai stood in front of the workbench and gestured to the saw while answering casually: "But the designer is trash. If I were his boss, he would definitely fire him directly."
"What do you mean?" Old Liu was in high spirits, had a smile on his face, and asked Guo Tailai.
"You require the engine crankshaft to be coaxial at no more than 5 microns, which is normal. The requirements for high roundness and cylindricality are also normal." Guo Tailai kept staring at the workpiece with his eyes and replied: "But your other ordinary size requirements are also 5 microns. Isn't that a problem to play?"
"The normal expansion coefficient of steel is more than ten times, minus six times for every degree Celsius, and the length of a workpiece of one meter long changes by more than ten microns." Guo Tailai continued to explain without raising his head: "You have such high accuracy requirements but do not mark the temperature requirements. Isn't that a half-baked person? Moreover, the working temperature of the crankshaft is at least dozens or hundreds of microns higher than the normal temperature, and the size expansion changes have exceeded dozens or even hundreds of microns, not to mention the disturbance and deformation caused by complex working conditions. Is it a big deal to require 5 microns?"
"So, if the designer is not a garbage, it is intentionally increasing the processing cost and processing difficulty, and increasing the extra expenses out of thin air." Guo Tai said this and saw the workpiece in his hand. Then he looked up at Old Liu and said, "Old man, do you think such a designer should be fired?"
"If I were to do it, I would have fired." Old Liu smiled happily. Looking at the fat man's unformed workpiece, he clicked the part on his hand with great interest: "What are you going to do?"
