Successful fruit picking system

The video continues, a pair of shoe buckles are designed into a square or nearly diamond-shaped main body shape, and hollow elements should be added.

This design actually has a lot of loss,

Because even if it is not a hollow part, just talking about the square itself, it is not as good as a round or oval shape that can retain the large volume characteristics of the diamond to the maximum.

Think about it and know that a square shape requires cutting off the four sides of a pebble-like diamond along a string similar to a circle.

If the finished product is round or oval, the next part can be kept.

However, Zhai Xiaoguo said that the round shoe buckle is made, which has the kind of round and oval cheap brooches in the online 5 yuan jewelry store.

Not gorgeous, not stunning, not expensive...

In that case, how to harvest money from the rich and balance the world?

We just want to use 150 carats of diamonds to reduce the remaining 100 carats to reflect the hard-won and preciousness of this 100 carats?!

Therefore, it doesn't matter if you lose a little quality, as long as you watch the cattle batch, others can't make it!

The teachers and students want to vomit: nonsense!Of course not in other people's homes!Have you ever seen a diamond with a hollow design?

What kind of cutting is used for the hollow part?

How to polish the cut out hollow structure?

Traditional diamonds are polished with a "convex structure", which means that although each cut surface is flat, these flat surfaces together constitute an overall convex structure.

In theory, any diamond, no matter how complex the facet is designed, only needs to find the right angle, even if there is only one flat grinder, all of its faces can be polished by directly leaning against the polishing surface of the flat grinder.

But it won’t work where there is a concave structure...

For example, for their all-diamond ring, the outer side of the ring structure can be polished well no matter how many facets are designed, but how to polish the inner surface of the ring?

If the material is changed to jade or wood, the hollow carving technique with concave structure is very common. Because the material is softer, the inside of the hollow structure is easier to polish.

But now it's a hard diamond!

Whether it is the inner side of the ring or the hollow part required by the shoe buckle, the inner side grinding becomes a problem. The grinder or belt machine that processes the convex structure cannot penetrate into these small spaces at all. Even with hand drills, it is easy to have lack of grinding. Uneven, irregular situation...

Shouldn't it be a little bit of rubbing with the sandpaper in your hand, without stopping the electronic caliper card, and then rubbing it for months or even years?

In other words, does it degenerate into a handicraft industry?

Some people insist that handmade products are the guarantee of excellence, because the accuracy of handmade products is higher than that of machines, as long as you have the craftsmanship...

In some special fields, such as surface grinding and rounding of regular shapes, it is indeed possible to manually grind to several decimal places with high precision.

However, this has already added some restrictions...

How much accuracy can be guaranteed for workpieces with irregular shapes?

The blades of aero engines, because they are relatively regular and large-area grinding, there have been some processes of grinding by hand.

However, with the improvement of precision requirements, in the end, we can only find a way to replace it with a machine, such as a multi-axis CNC grinding machine...

It is easier to understand by replacing it with a chip that does not have a large area for manual use.

Can the nano-scale microcircuits on the chip be carved out with a hand knife?

Assuming that it can be carved out, can a circuit unit calculated in units of 100 million be carved out in ten thousand years on a chip?

Therefore, the quality of the machine, that is, in terms of "quality" and "quantity", is superior to manual.

The most important thing is that people don't need to feel sad or dissatisfied about not being able to compare with machines, they should be happy instead!

Because the advancement of productivity has liberated the labor force, people don’t need to spend another 10,000 years to carve a chip by hand, and dozens of generations are exhausted, but it may not be guaranteed to be used...

This is also the reason why the mechanized industry replaces the handicraft industry, because it is good, not bad.

Otherwise, people will only use bad machinery industry to replace good handicraft industry with their brains...

Of course, the accuracy of manual work is higher than that of machines.

The past exists, today exists, and the future will also exist.

But it must be understood that the premise for its existence is that in some industries, the product itself requires low accuracy, and it is not necessary to spend thousands of trillions to create an industrial chain with nanometer precision like the chip industry.

Moreover, the market size of these products is not large, and the cost of inventing the machine cannot be earned at all, so it is better to use your hands.

In this regard, it is generally only manual for specific processes, most of which are still mechanized...

For example, watches, cars, etc. carefully crafted by hand craftsmen, let’s not say that these things are originally mechanical creations made by machinery, but they are mechanical creations.

Even if manual work is used, in the entire industrial chain, only a few processes are done manually.

This is because their market scale is not large and only needs to meet the needs of a small number of wealthy people, so slow work and a small amount of meticulous work is enough, and invest more money to invent a highly accurate machine to replace the few handwork. The process is not cost-effective...

This is mentioned because Zhai Xiaoguo asked these jewelry design students to use technology to solve the problems they encountered. Some students said:

Their jewelry design is not the same. Many times people tend to be hand-made, while mechanical creation is despised.

I also let Zhai Xiaoguo watch a few self-media videos about making jewelry...

Zhai Xiaoguo saw that someone in the video insisted that he didn't use any modern tools and used the so-called traditional craftsmanship from beginning to end...

Zhai Xiaoguo believes that as long as it does not violate the law and morals, everyone has the right to do what they like to do, including this person who emphasizes the need to use traditional handicrafts.

The problem is that you have to despise the mechanical creation to set off the hand-made cattle batch, step on the handful, this is wrong!

This buddy said that if you make a gold ring, how can you use an electric furnace to melt small gold ingots?

You must use charcoal fire and a hand-drawn bellows!

However, let’s not discuss whether gold was melted like this in ancient times.

The reason why this man can be so willful, choose a method that wastes more energy and time than melting gold with an electric furnace, without worrying about starving to death, is because the modern large-scale industrial system has liberated his labor force, and he does not need to be in the earth every day. You have to look at God's wink when you plan to eat!

The coke or coal he uses to melt gold, even if it is difficult to concentrate heat with charcoal, is supported by modern industrial systems...

Coal is dug by a large industry, coke is drilled by a large industry, and charcoal is artificially planted from a fast-growing economic forest...

what?Did you go into the mountains and chop wood to burn charcoal?

Well, let’s not say that cutting down trees and burning charcoal is illegal or not,

That mountain can have wood, probably because it started to mine fossil fuels on a large scale after industrialization, and then worked hard to close the mountain for afforestation, the state gave subsidies, and the village officials were all over the mountain to catch sheep and did not allow grazing, logging, or even artificial tree planting. Okay……

Zhai Xiaoguo said to this group of students who had clearly entered the university to study science, but did not use scientific methodology to guide themselves in solving problems, let alone a historical materialism:

If you can't think of a way to solve the diamond polishing problem with modern technology, you can only polish it slowly by hand until it is old, then there is no need to go to college!

Why eat 4,500 yuan in one month of food, plus the supply of various experimental materials?

You can find a small manual workshop, which not only requires no investment, but also directly produces output...

Of course, even if you find a small handicraft workshop, it is probably supported by various modern large-scale industrial systems as the background, and it is not the real handicraft that people imagine...

It’s not that Zhai Xiaoguo looks down on handicrafts, but that many people clearly enjoy the life brought about by the modern industrial system, but they always think that modern science and the modern industrial system are bad, polluting, used to torture people, or so-called The ancient and traditional pastoral and handicraft life is good, only advanced...

To be honest, if productivity is still at the stage of farming and handicrafts, then people with this kind of thinking are working hard every day, basically living in their 30s will reach the age when the loess is buried. There is time to criticize modern science. And industry...

The ancient handicraft industry does not exist and does not require modern universities, let alone the support of modern technology.

Because in the macro-low-speed natural environment that people have evolved, they do not have high requirements for understanding and mastering objective laws.

If you don’t need to use rockets to launch satellites, you just need to build a sky monkey, you really don’t need the blessings of modern science and modern industrial systems, you can do it by hand...
