Chapter 71 High Precision Lathe (Part 1)

"Master, come and give me the electricity." Guo Tailai asked Mr. Liu to be the first person to start the lathe.

Mr. Liu was not too polite. He watched Fatty build this lathe bit by bit. During this period, he used his own experience to give Fatty a lot of advice. It can be said that this is the hard work of the two of them. It's the first time to power on and debug, Mr. Liu will do his part.

Hum, the motor starts to spin. Listening to the voice, Mr. Liu was taken aback, the voice is so low?

The motor was designed and installed by Guo Tailai, and the spare parts are manufactured with an accuracy of 0.5 microns. In addition to Fatty’s excellent assembly skills and dynamic balance debugging skills, the motor turned out to be just a low hum when it was running. Can't hear.

Guo Tailai pretended to put a coin on the protective cover of the motor, and the motor turned for two minutes, but the coin standing on it remained motionless.

Mr. Liu knew that Guo Tailai's motor must be unusual, but he didn't expect that besides the low noise, there was not even the slightest vibration. Although the vibration of the motor is minimal, such a smooth one is absolutely rare.

Unbelievably, he put his hand on the protective cover of the motor, and Mr. Liu felt it carefully. Ordinary motors, with the sensitive touch of Liu's old fingers, can definitely detect more than one trace of vibration. But the motor made by Fatty didn't even vibrate at all, it was unbelievable.

The motor is quiet, and the entire lathe is not so noisy. Of course, the tool is not being processed now, so the voice is naturally very low.

The lathe is semi-automatic, it can feed the tool manually or automatically, the only thing that is not so high-end is that it is just a lathe.

Guo Tailai changed the motor, the gearbox, the guide rail, and everything that can be changed. Even the size markings are different. The scale enlarged by several stages of gears can be directly accurate to the unit of micron. The only thing I have to say is that I haven’t made it, that is, the blade head. I don’t have a good blade steel on hand, so I can only use the mass-produced goods bought outside and then finely grind it myself.

If it were someone else, it might take a day or two to adjust the various dimensions of the new lathe. Guo Tailai doesn't use it here at all. He can know the exact size with his eyes and hands. The calipers and dial gauges used in the workshop are not as good. Guo Tailai's eyes are precise. When the lathe is assembled, the debugging has actually been completed synchronously.

Fatty made a high-precision lathe, so naturally he would not turn blanks on it, so he directly found a semi-finished short shaft, clamped it with a jig, fixed the tail top, adjusted the position of the turning tool, and then entered the tool.

"Well, it's okay to feed the knife at a steady and uniform speed." Mr. Liu looked at the side and nodded. Level 9 fitter, it is very simple to do some lathe work, and he is also qualified to comment.

It is very simple to turn a short axle, and the fat man's lifting is as light as it is, and he will cut it to the end.

"The outer diameter is 1.5 centimeters now. To be exact, it is 15.02 millimeters. There is a margin of 1 wire in the radius." After withdrawing the knife, Guo Tailai directly stated the size.

Mr. Liu took a dial gauge and began to measure carefully. It's not that he doesn't believe Guo Tailai's eyes, but he wants to measure it himself. Otherwise, the referee and the players are Guo Tailai, wouldn't that give Fatty a chance to cheat? What's more, he really wants to know whether this 1-silk margin can be accurately driven.

Seeing that Guo Tailai made a slight adjustment on the enlarged scale, he continued to advance the knife. Immediately, a puff of filaments bloomed on the part where the long axis entered the knife. The amount of 1 silk is half thinner than a human hair, and this entry of the knife is exactly a very thin silk thread.

Guo Tailai stared at the situation of the knife entering, until the knife was finished, and after operating the knife back, a smile appeared on his face: "Master, the car dropped a thread, no more, no less."

Elder Liu couldn't wait to go up with the dial gauge. Seeing the measurement results, Elder Liu almost narrowed his eyes with a smile. However, he was not too proud, but directed Fatty to continue to feed the knife, this time changing to 5 microns, then 3 microns, 2 microns, and finally 1 micron.

When the 1-micron cut was completed, the measurement was done and it was still extremely accurate, Mr. Liu couldn't bear it anymore, his body softened, and he sat on the chair that the fat man put over in time. Suddenly, a nearly seventy-year-old man just shed tears.

Guo Tailai didn't say a word. He knew that Mr. Liu must be excited. In fact, Fatty himself was very happy. He personally built a lathe with a precision of one micron. A lathe can do it, and there is no need for a fat man to polish it with a fitter.

"Okay! Fatty! Good!" Excited, Mr. Liu could only say yes and call Fatty. After going back and forth several times, he finally said something else: "Retirement and accepting you as an apprentice really give me face!"

The master and apprentice sat in this dust-free workshop for a long time, basically doing nothing, just looking at the lathe and chatting.

Mr. Liu recalled many difficulties, people and things he encountered in his work, and expressed his feelings about the difficulty of being blocked by technology. Guo Tailai sat next to him and listened quietly. The old man probably held back these words for many years and wanted to talk to others. Seeing the breakthrough of this lathe today, it would be good for Mr. Liu to open up the conversation box and release it.

"Fatty, have you fallen in love with Zhao Yanyan?" At the end, Mr. Liu was almost venting, but suddenly the subject changed and turned to Guo Tailai.

Guo Tailai was taken aback by the sudden question, and immediately denied it: "No way, how could she have a crush on me!"

"If you like it, you like it. What's so embarrassing?" Mr. Liu is an old man. Guo Tailai can see his performance in the past two months. Something is on my mind: "Zhao Yanyan is such a beautiful little girl, it would be strange if you don't like her!"

"Have you told her?" Elder Liu turned to look at Guo Tailai and asked him.

"Dare not." Guo Tailai didn't want to hide it in front of the master, and said with his head down: "Sister, she said that she is not married, and she doesn't plan to get married in this life. She also said that if I can succeed in becoming a bodybuilder, she Just be my girlfriend."

"Then what are you waiting for?" Elder Liu laughed, "Hurry up and practice!"

"Do you think it's interesting?" Guo Tailai glanced at Old Liu resentfully: "His family can directly arrange for her to go to the Southern Group. Her family background is so good, and she is so beautiful, smart, and well educated. I am just an ordinary worker's family. is it possible?"

"How do you know if you don't try?" Mr. Liu certainly knows that Zhao Yanyan's family background is very powerful: "I went there on the day of her defense, and I have never seen her smile so happily. Don't you young people often say , there is still a dream, what if it comes true?"
