In Narita, Japan, there is a century-old eel rice restaurant. The door is a sheet of paper. For hundreds of years, eel masters have sat here and slaughtered eels. Before killing the fish, the master would carefully examine the table and even use a ruler to measure whether the table was flat enough. I asked him why. He says an uneven table could affect the eel's taste. I think he's exaggerating a little. But that's how the Japanese get their work done. I once worked in the conference room of a Japanese hotel. Every time there was a meeting, the leader would take me to measure whether the distance between each table was the same with a tape measure, and even calculate the steps needed to walk from the podium to the seat. I don't understand. Is that necessary? The leader said, yes! Indeed, when this spirit is integrated into all walks of life in Japan, you will find that they have made amazing achievements. For example, in the field of precision machining, the world's top three countries are: Germany, Japan and Switzerland. There was a small factory in Japan with only a dozen workers who made only one product -- dice. Love playing mahjong people know that the dice due to each side of different points, the center of gravity is not the same, so when the dice thrown down is unable to do absolutely fair. But the company has improved the accuracy rate to 99.999999%, the only one in the world that has mastered this precision machining technology. Founded in 1930, Okano Industrial Co., a small company in Tokyo's Okada ward, claims to be the world's leader in stamping. With only five employees, including Okano's wife and son-in-law, they created the world miracle by producing the world's thinest syringe needle. When you're facing the needle, you barely see it, and when it enters your body -- let's just say, experiments show, it's like being bitten by a mosquito.
In 2017, Callum Hasegawa from Japan shared a six-second video that got crazy likes on youtube, showing a metal block with a bulge on it, which you can then slowly press down into the bottom to become a smooth surface. The most striking thing about the surface is that it is surprisingly smooth and has no cut gaps, demonstrating the power of Japanese precision metalworking. How did you do that? The machine? No! It's the power of people! After the machine is roughed up, the skill of the veteran artist is revealed. Ifeng.com once described how the old artist is to create an absolute plane: Experienced craftsmen with the shovel a knife a knife to get rough machining of plane, at the same time also in the plane of shovel out the need to do a reference plane, and then paint on the control plane, the plane processing in the control plane sliding, then processing plane on part of the color and contrast in the plane off color part is respectively is higher than that of two plane to part, Need to shovel again, this process is repeated until the two planes on the color is completely uniform so far, this time the plane left on the knife marks just as the lubrication groove, killing two birds with one stone. But even so, you can not guarantee that you can get an absolute plane, veteran artists will generally make three planes, two of which are exactly the same, to make an absolute plane. Germany, Japan and Switzerland are the countries with the best reputations in this field. So why do these three countries do so well in precision machining? In fact, there is no mystery, just patience, diligence, constantly polishing the product. Of course, after the Meiji Restoration, Japan has been learning German skills, which can be regarded as the primary school of Germany in Asia, but the meticulous and serious attitude of the Japanese also makes Japan a better country
