Chapter 8 How Is It Possible (Part 2)

"Grandpa, I'm going to use your room and those things for a few days." Guo Tailai didn't care about the faces of everyone in the room, and said to Old Liu, "Also, you promised to teach me how to press the bottom of the box. Don't play tricks!"

Guo Tailai dropped his things and left. He didn't stop working for three and a half hours, and his chest was already hungry. Basically, after saying these words, the fat man had reached the limit of his patience, and without waiting for a few people to respond, Guo Tailai ran away in a hurry, and if he didn't run to the cafeteria, he would have nothing to eat.

Factory Manager Li and Manager Wan and his son, who were waiting anxiously in the office, were completely speechless. finished?

Director Li doesn't just sit in the office, he also has a craft, otherwise how can he determine how long it will take for the fitter to polish by hand? Needless to say, Manager Wan was responsible for the front-line production, and had communicated with the factory's senior fitters in advance, so the estimated time would definitely not be too far behind.

Facing Fatty, it only took three and a half hours to complete the workload that they estimated would take a sixth-level fitter for a month. Their first reaction was that it was impossible!

However, this job was supervised by the retired ninth-level fitter Mr. Liu, and they couldn't say anything to question, they could only scream in their hearts, how could it be possible?

"Measure it!" Old man Liu pointed to the box on the table, and he went to the chair next to him and sat down.

Not to mention that Factory Director Li and Manager Wan were terrified, even Mr. Liu himself was in lingering fear at this moment.

Guo Tailai, that fat man, shot too fast, and it wasn't the kind of finishing method at all. The basic skills are learned solidly, but the courage to do it is too great, and Old Liu is in a cold sweat watching it.

There is only 1 thread of machining allowance. When Mr. Liu passed by himself, he thought that the fat man was still carefully measuring the dimensions and comparing them with the drawings. As soon as he entered, he found that the fat man had already clamped the semi-finished crankshaft, and he was holding the last crankshaft in his hand. A fine diamond file is used to file down the outer circle of the small head hole of the connecting rod.

Mr. Liu almost screamed out. He finally knew that he was most afraid of distraction due to external factors when polishing by hand, so he forcibly held back. He didn't make a sound until the fat man's file was in place.

"What are you doing?" Elder Liu asked angrily at Guo Tailai after closing the door of that small room.

"Machining the crankshaft!" Guo Tailai looked innocently at the furious old man Liu: "Didn't you ask me to do this? Not to mention, your tools are amazing, many times more refined than those outside."

"Did you do this?" Boss Liu was furious, and yelled at Guo Tailai: "Do you know how much machining allowance there is? You still need to use a file, such a little allowance is only enough for fine grinding! I I was really blind yesterday!"

"Please!" Fatty is not used to Old Man Liu's habit of relying on the old and selling the old: "Isn't it just leaving a machining allowance? How big is it, do you care whether I finish grinding or filing? Come, measure!"

While talking, the fat man took out a dial gauge from the tool box next to him and threw it to old man Liu. Really, what's wrong with making me work and whimpering? If it weren't for the fact that the entire fitter workshop was respectful to old man Liu, Guo Tailai wouldn't be so angry.

Of course Mr. Liu has to measure it. If the fat man doesn’t know how serious it is, the crankshaft will be useless no matter how hard the diamond file is.

However, Mr. Liu measured several times in a row, measured several positions of the file, and the readings of the dial indicator were exactly the same, all of them were 30.010 mm, which was exactly the same. If you file off another thread on the opposite side, it will be exactly 30 mm in diameter marked on the drawing.

That is to say, the fat man just filed off one thread with one file. The feel and the precision of the control are simply amazing!

Even Mr. Liu himself in his prime would not dare to say that he could file off exactly one thread in one file. He had to carefully divide it into several times, and file off the outer layer bit by bit. You have to measure several times accurately and take the average value before you dare to continue. How can it be done with a file like Fatty?

After the fat man changed his position again and finished it with a file, Mr. Liu measured it several times to make sure that the fat man's hand was extremely stable and accurate to the point of jaw-dropping. After that, Mr. Liu was sure that he had definitely found a treasure.

After three times, Mr. Liu stopped taking measurements every time, and watched the fat man file one by one in order to complete the final step of finishing the crankshaft, which originally required high-precision CNC machine tools, bit by bit. Filed to size.

Fatty knows it in his hands and knows it in his heart even more. The plane is fine, as long as the file is accurate and in place. The inner diameter and outer diameter of the big round hole and the small round hole of the connecting rod are all round, which is very difficult to process, but just like this, the fat man follows the arc curve, and it can be done with one file.

This is no longer the pinnacle, but the skill is close to the Tao, uncanny workmanship. Mr. Liu didn't even know how to describe Fatty's craftsmanship. Although he was a ninth-level fitter, he didn't dare to say that he was compared with Fatty in this regard.

The only thing that can be stronger than Fatty is the various incomparably rich experiences that have been accumulated over the past few decades. Since Fatty has such amazing skills, Mr. Liu wished he could imbue him with everything he knew.

So, the fat man started working on the side, and Mr. Liu told him the precautions, techniques, and processing methods of various corners and curved surfaces in advance, stuffing it into the fat man's mind like indoctrination.

Guo Tailai's basic skills are very solid, and the two of them actually work very easily, without the kind of prudence that people outside imagined, as if they were facing a big enemy.

During the chat, Mr. Liu knew Guo Tailai's name and the purpose of coming to the fitter workshop.

Guo Tailai also knows that Mr. Liu is definitely a master. He has learned these things from his father. Mr. Liu has more subtle, more secure and creative methods and techniques to realize them. First-line manufacturing, but these valuable experiences are definitely what Guo Tailai dreams of.

The two chatted relaxedly, and without knowing it, even the hand-finishing behind the file and the back was completed in this way. At the end of the day, the fat man polished it quickly, and the two of them didn't waste any more time, and took the things back to the office directly.

Only now did Mr. Liu realize that the finished product had not been measured by him.

What makes Mr. Liu even more horrified when he thinks about it is that from the beginning to the end, he never saw the fat man move the dial indicator, and he has been working all the time, and he has never measured it once.

"Qualified...qualified...qualified...qualified..." Manager Wan and Factory Manager Li each held a crankshaft and the other held a dial indicator, comparing them to the drawings and kept measuring, saying Qualified one by one.

In the end, all marked dimensions are qualified, and both the inner and outer circles are completely standard. They estimated that one crankshaft would require a six-level fitter to finish grinding for a month, and the fat man finished two crankshafts in three and a half hours. How could it be possible?

"How did he do it?" Director Li was going crazy, is this still human?
