......
Knightley asked him if he understood the difficulty of the precision processing industry, especially the high-precision processing of similar instruments.
The Master Craftsman showed an unpredictable smile and walked to the pile of precision mechanical parts carefully placed on the cushion.
Escapement splint, hour wheel, span wheel, needle wheel, handle shaft, tourbillon, spring.
These parts, only from the perspective of polishing precision, can indeed make a large number of old workers in China ashamed to drill the ground.
"The problem is with the parts you fit."
The words of the Master Craftsman made a group of white-bearded old workers under the Stafin Group unable to sit still.
They blew their beards and stared, asking the Master Craftsman why to conclude that the fault was on them.
"Even without measurement, we came to such a conclusion." Knightley shook his head and smiled with some confidence: "You are laughing at our Stafin Group without any basis."
The Master Craftsman continued very calmly: "The watch needle appears to be in a break-point working state, but you can't even detect the most basic fault detection."
"Do I need to laugh at this kind of thing?"
Knightley and the group of craftsmen behind him seemed to be gripped by a key point, and their expressions suddenly solidified.
The maintenance and repair of mechanical watches is exactly what their group of craftsmen are good at. On the fifth floor of the shopping center, there is a separate floor of Gothic decoration, full of aristocratic nostalgia of the famous clubhouse.
It is claimed that any antique mechanical watch can be repaired there, and it also collects the entire Hua Xia, the most complete limited edition famous watch.
Now they can't even detect the fault of a mechanical watch designed and manufactured by themselves.
All the parts have not been damaged or deformed, nor have there been any changes in accuracy.
The craftsmen had no choice but to throw the reason to Hua Xia, but the Master Craftsman hit the nail on the head and pointed out their cowardly behavior.
Yes!
The mechanical watch made by oneself, but even the most basic faults can't be detected. Does this need people to laugh at it?
It should be them, laughing at themselves.
"You... how do you prove it?" Knightley stared at his eyes, all unconvinced.
"Do you want to know which part is the problem?" The Master Craftsman used his hand and inadvertently slipped over a part.
"How about this? I'll give you some answers."
"If you still can't figure out where the problem is after I finish speaking." The Master Craftsman looked around at the white-bearded craftsmen and nodded, "Then you really are …"
"Stupidity to a whole new level."
Perhaps it was because he didn't have enough confidence, but when the old man who looked like a farmer swept his gaze over him, he was stunned. This group of craftsmen, who had high attainments in the field of precision components, suddenly felt uneasy and nervous.
Strangely …
He was worried about becoming an idiot.
This feeling was like a teacher saying in front of his students, "I'll tell you how to solve a problem. If you still can't figure out the correct answer, then you might as well pack up and go home to farm."
In the wild thoughts of these craftsmen, the Master Craftsman calmly gave the answer.
"You've made a mistake called 'having high expectations but little ability'. “
"Making a large mechanical watch is not too difficult a technology in itself. But you blindly think that making a large mechanical watch, you can still control the travel time error within the ten-second error range of ordinary wristwatches, and use the same complex structure design as a wristwatch. "
"The same processing technology, and design ideas, to make different sizes of parts. If mechanical manufacturing is so easy, then what are 10,000 tons and 50,000 tons of hydraulic hammers? Just use 10,000 tons of them all. "
"I won't say that the precision of the parts you make is worse than what I process with my eyes closed."
"Let's talk about the most important tourbillon in it."
"The balance on the tourbillon looks beautiful, but you actually use this kind of mentally retarded wire structure to surround this giant mechanical watch with a diameter of three meters?"
After the Master Craftsman finished, from the young vice president Knightley to the following group of white-bearded craftsmen who looked older than the Master Craftsman, all became cross-eyed and stared at the Master Craftsman.
He didn't beat around the bush, nor did he hide any hidden hints. It directly tells them that the problem lies in the tourbillon they are most proud of.
And even the parts on the tourbillon are pointed out in detail.
Their redesigned balance wheel is equipped with three layers of blue steel hairspring.
A tourbillon is made up of more than seventy parts. It is the core device that distinguishes between noble and ordinary mechanical watches.
An ordinary mechanical watch, for example, costs 10,000 yuan, and the mechanical watch with the tourbillon device will sell for 200,000 yuan.
The tourbillon, which is specially designed to overcome gravity, has successfully controlled the travel time error of the mechanical watch to the second level. The balance wheel above the tourbillon and the hairspring above the balance wheel are soul devices.
As one of the largest manufacturers of watch parts in Switzerland, the Starfin Group makes tourbillon.
Of course, when making this huge mechanical watch, it will naturally use tourbillon to show its noble lineage.
The tourbillon controls the movement of the second wheel, and the second wheel moves one circle, and the minute wheel moves one circle, and the minute wheel moves one circle, and the hour wheel moves one circle.
Therefore, the tourbillon is the foundation of accuracy, so of course, the parts on the tourbillon have problems, and the whole clock will follow.
"No... No... No." A white-bearded craftsman stammered and said with panic: "If there is a problem with our winding structure, why did it run for three days before, and there was no problem?"
The Master Craftsman asked him strangely: "Because of the idiocy of the designer, are there still few examples of operational failures in a short period of time?"
The craftsmen quickly surrounded the tourbillon like a celestial globe, and the most important balance wheel above has been removed.
The Master Craftsman said that their design of the balance wheel winding wire was simply retarded.
But all the balance wheel hairspring is the same winding wire scheme as a mosquito coil. Although they have made some changes on the balance wheel, the hairspring has not moved.
After the Master Craftsman pointed out, they looked at the structure of the hairspring again and found some clues.
The elastic hairspring like a mosquito coil can evenly distribute the gravity deviation caused by gravity. Now the size is larger, it seems to be a hairspring...
I can't tell the feeling, but I feel something is wrong. But limited by the lack of technology, I can't see what's wrong.
"Do you think that this structure can't distribute the gravity deviation more reasonably?" The Master Craftsman has a kind appearance of a teacher: "Then the hairspring may vibrate or something like that?"
"Hmm?"
This group of old craftsmen who have been assigned to the idiots, as if they were struck by thunder, trembled all over. (To be continued.)
