Luxury Goods: From Handicraft Workshops To Domination Of The World

Chapter 146 Observatory Certification, Micron-Level Cnc Machine Tools, Full Cnc Integrated Watchmaki

"If I remember correctly.

"Like Vacheron Constantin, watches and movement parts worth tens of millions can only be polished on the top machine tools in Prussia. W

"The movement parts can achieve micron-level precision, and they are very light and thin."

"To set up a watch production line, the first step is the machine tool."

Back to Jianjia Workshop.

Gu Bai thought about it in his heart and cleared his mind.

Inside a factory building.

Gu Bai focused his eyes, and the store interface appeared in front of him, [production facilities], [technical documents], [talent training], and [laboratories].

Machine tools, known as the mother of industry, are also surprisingly expensive, often costing hundreds of thousands, hundreds of thousands of extravagant points.

If you want to buy these top goods, you have to sell more luxury goods!

Fortunately.

Watch parts are all the size of a grain of rice, so they don't need a large machine tool, but high precision.

【Micro-scale ultra-small CNC machine tool】

【Price: 10000 luxury points】

[Description: A six-axis linkage machine tool that can process parts of 10cmx10cm*10cm with a precision of 1 micron. 】

Ok...

The precision is really high, 1 micron level!

The size is also really small, the largest is to process a mug.

Of course, it is enough to produce movement parts.

"place!"

With Gu Bai's thought, boxes containing machine tool parts appeared in the workshop one by one.

After the workers have finished debugging, they can process the parts.

next.

Gu Bai spent another 2,000 luxury points to buy a high-end coating process of "green gold coating" in the [Technical Documents] column. 01

The essence of the green water ghost lies in green, and high-grade coating technology is essential.

Then, in the [Talent Training] column, I spent 2000 luxury points to buy a skill book, "Senior Watchmaker Skills".

after use.

Numerous watchmaking experiences were integrated into Gu Bai's memory, and in an instant, he had the world's top watchmaking skills.

three days later.

Plants, equipment, raw materials...everything is taken care of.

Gu Bai came to the machine tool console, took a deep breath, and input the CAD part drawings into the machine tool computer.

This basic "Pluto movement" requires more than 300 fine parts.

"start up!"

Gu Bai pressed the start button, the mechanical arm moved flexibly according to the program, and began to turn and mill an alloy plate, and soon a CNC watch case was produced.

The so-called CNC processing is very similar to engraving, using several cutter heads to carve the target into the desired shape.

Gears, cover plates, clutch levers, escape wheels...

Crown, hands, hours, minutes...

Cover, bottom cover...

Groups of watch parts are integrally formed and CNC machined out.

CNC process is quite expensive and generally only used in core parts.

Like Gu Bai, the full CNC process is too expensive, and ordinary companies can't do it, and they don't have the technical strength.

"This gear."

"It's thinner than expected."

under the electron microscope.

Gu Bai picked up a piece of gear with tweezers, and observed it a little. It was as thin as a feather, and according to the scale, the thickness was about 50 microns, or 0.05 millimeters.

How thin is this?

For the 20 million Vacheron Constantin “Attic Craftsman” series, the thickness of the gears should be around 0.30 mm, a difference of 6 times.

The benefits of thinness are self-evident.

Mechanical watches, dojos in snail shells, every bit of space, every bit of weight is very important.

By reducing the thickness, more space can be made for the waterproof function.

Certainly worth mentioning.

Among the parts of the movement, the bearing needs to be made of precious stones, and the durable ruby ​​is the best. This kind of gemstone bearings cannot be processed by CNC machine tools naturally, and they are all processed by entrusting gemstone factories.

Jian Jia's words.

Gu Bai replaced the bearing material with red broken diamonds, calling it diamond bearings.

Has better wear resistance.

"Mr. Gu, these parts are too delicate."

"Fortunately, this is a dust-free workshop, because the family wears a mask.

"Otherwise, if you are not careful, if you take a breath, all the parts will be blown away."

Aunt Liu stood aside and did not dare to breathe.

Every part is extremely delicate in her eyes, even with an electron microscope, there is no trace of flaws, it is simply perfect.

"However, such an ultra-thin gear."

"It's a hassle to assemble, isn't it?"

Aunt Liu frowned again.

Not only her, but even some watchmakers behind her also showed embarrassment. It is hard to imagine how difficult it is to combine gears that are as thin as cicada wings.

"It's not a big problem, just look at me."

Gu Bai smiled.

Now, he is already a "senior watchmaker", and with the background of a god-level tailor and jeweler, it is not a big problem to assemble a movement.

Come to the console.

Open the 50 times electronic magnifying glass, the inside of the top-level mechanical watch is too complicated, and requires a 50 times magnification function to facilitate assembly operations.

Haute Horlogerie, not the cover, is quick to assemble.

In just 2 hours, a complex and exquisite mechanical structure appeared in front of Wang.

tick, tick,

The gear set rotates precisely like a planet, full of mechanical beauty, as if forming a precise planetary galaxy.

The escapement mechanism beats the balance wheel back and forth.

The hairspring keeps beating, and the beat rhythm of the escapement mechanism is precisely controlled at 1S/time, making a ticking, ticking timing sound.

hiss~

Aunt Liu and the others made a gasping sound.

Aunt Liu has owned several mechanical watches, but those movements, compared with this "Pluto movement", are like antiques hundreds of years ago.

It's too bad.

The watchmakers on the scene, one by one, also widened their eyes.

They are all veterans, have helped many foreign big-name OEMs, and have seen many big-name movements.

There is one thing to say.

This "Pluto movement" only has the function of time and calendar, and the structure is not complicated, but it has a different kind of mechanical beauty when you look at it.

"This movement, in terms of design, seems to surpass foreign big-name movements."

"On the parts, all ultra-thin, micron-scale parts are used."

"President Gu's craftsmanship is also very top-notch."

"I think this is why this movement looks so precise, coordinated and beautiful."

An old watchmaker said with emotion.

The crux of the problem was pointed out, which attracted a lot of recognition.

"All right."

"I'll rest for a while, and you guys test the performance of this movement first."

Gu Bai yawned.

He has to do work on the dial and case early tomorrow morning, so he is going to take a rest first.

The work here is left to Aunt Liu and the others.

movement.

First measure the weight, place it on the measuring instrument, and a number jumps out: 35g.

For a diving watch movement, this weight is quite light.

Lightweight, will greatly improve the wearing feel.

Next is volume.

The diameter has not changed, it is still 29.6mm.

But thanks to the ultra-thin gear structure, Gu Bai polished the column structure again, and the thickness is much thinner than the expected 4.25mm, reaching 2.95mm.

Don't underestimate the thickness of 1.3mm, it is an exaggerated figure for a mechanical watch.

"It's incredible."

"The weight and volume of this movement are almost perfect."

"However, for a movement, the most important thing is the accuracy of travel time. If the time is not accurate, everything is out of the question."

Aunt Liu took a deep breath.

Good movement.

Rotten movement.

The simplest judgment is whether the time is accurate or not.

The most authoritative certification in this regard is the "Certificate of Observatory Certification" issued by C.O.S.C (Swiss Official Observatory).

This certification is very strict.

There are altogether three laboratories in Riva, Bill and La Chaux-de-Fonds. The accuracy of the movement will be tested in different humidity, temperature and weather within 15 days.

Watches that pass the test will be engraved with the words "Chronometer"|The price will also rise.

The average daily error needs to be between -4 seconds and +6 seconds.

Generally speaking, it is 5 seconds error.

but.

Observatory certification is expensive, and it is naturally unrealistic to travel to Ruishi.

"let's start."

Aunt Liu opened the mouth and arranged a test time.

This requires the use of professional equipment.

Put the movement in a glass shell, place it on a simulated arm, and press the "start button", and the simulated arm will rotate in a simulated manner.

At the same time, the calibration electronic clock on the side began to count 790 hours.

In this case.

You only need to check the difference between the running time of the movement and the time of calibrating the electronic clock to infer the error of a movement.

"Guess how accurate it will be?"

"For domestic brands, within one minute, it is considered a success..."

"I hope I can advance for a minute!"

"If it's 30 seconds, then it has reached the level of the Ruishi movement, hahaha

"Based on the perfection of this movement, perhaps, it can really enter 30 seconds!"

"It's possible, but keep a low profile"

"It won't be cut into 5 seconds, it's an observatory-level standard!"

"It's a bit difficult..."

"impossible..."

"Hurry up tomorrow..."

The watchmakers talked a lot.

There was a look of deep anticipation on his face.

They are all masters.

Naturally, it can be seen that the design, parts and craftsmanship of this movement made by Gu Bai are very top-notch.

They are also very curious about the accuracy and how much it can achieve!

"Okay, let's go back and rest.

"See you tomorrow!"

Aunt Liu couldn't help but said in anticipation.

Test accuracy.

It takes at least 12 hours.

She also secretly looked forward to tomorrow coming sooner.

Overnight.

In the early morning, Aunt Liu and the watchmaker entered the dust-free workshop in a hurry without washing their faces or putting on makeup.

12 hours have just passed.

now.

Calibrate the electronic clock, display the time, 12:00:00:150 milliseconds.

The time displayed on the movement is 12:00:00.

Such a guess.

Within 12 hours, the time difference between the two basically does not exceed 1 second. If you want to measure detailed data, you need to look at it for a few more days.

But even so.

It can also be preliminarily concluded that the 24-hour error of this movement is at most within 2 seconds!

Error within 2S!

This is definitely more accurate than the Swiss Observatory certification!

Pluto movement, isn't it about to take off?!.
