Appearing in the eyes of Ye Qing, it is a silver-white Standard 6 angle nut.

Pick up this nut gently, Ye Qing’s first reaction is that this nut is very heavy.

Standard nuts of the same size are about 7 grams. Ye Qing often deals with these things and is very accurate in grasping its weight. But starting with this nut, the weight is around 5 grams.

The increase in weight means that this nut is made of a denser, harder alloy.

When Ye Qing pinched the alloy nut in his hand and aimed at the crystal lamp above his head to observe the thread on the inner wall.

Ye Qing, who had been hardened by monsters, was surprised to be unable to bear.

There is no thread in this nut.

Inside some crystal nuts, under the light, there is a faint reflection of metal.

If there is reflection, the metal mirror is representative. But the inner wall of a nut is as smooth as a mirror like a seamless precision tube.

Without a threaded nut, can this be called a nut, perhaps a metal washer is more appropriate.

What is a nut?

Nuts are the most common metal parts in modern industry and life. Nuts and screws, the two are tightly combined to fix the principle of objects, even the first grade children know.

The inside of the nut is called internal test thread, and the top of the screw or bolt is called outside thread. Only 2 nuts and screws of the same specification can be connected together.

The diameter is the same, and the pitch between the threads is the same.

If there is no thread, how to tighten the connection with the screw?

Ye Qing believes that Japan Technologies impossible committed such a mistake that violated the common sense of physics. Since they proudly gave this nut as a gift, there must be something in this nut.

“Is there a magnifying glass?”

Professor Cai Chenning has some solemn nodded, handed over a Kalander 300 times portable Microscope.

Portable Microscope with its own light source is usually used to observe the surface of jewelry, and the surface roughness of metal materials. It is only the size of a cell phone and is very suitable for carrying.

After adjusting the resolution and light source, Ye Qing aligned the lens of the portable Microscope with the inner hole of the nut.

Ye Qing’s face has also become solemn, under 300 times magnification, the inner hole of the nut that seemed to be as smooth as the mirror surface. There was actually one after another internal test thread. These threads were surrounded by a circle, and the spacing between the pattern teeth was too small to be incredible.

Under the observation of 300 portable Microscope, you can barely see a trace of depression between the teeth.

How thin are these striated teeth?

The thickness of a hair strand is 0.06 mm on average. However, a hair strand can be easily seen with naked eye. If the hairs are lined up neatly and there are gaps of the same thickness in the middle, can it be seen by the human eye?

A closer look can reveal the clues. Ye Qing pulled one of her hair down, placed it under the portable Microscope, observed it, and recorded the focal length and approximate width in the heart, and then aligned it to the inner wall of the alloy nut.

Compared with the hair thread, the pitch of the thread is too small to judge. This shows that the gap between the striated teeth is much smaller than 10% of the hair hair. As for how small it is, it has exceeded the human eye’s visual analysis ability.

“We measured it with a laser interferometer, the thread pitch is 0.2 wires, and the thread depth is 3 wires.” Professor Cai Chenning gave the answer.

“No wonder.”

Ye Qing understands that the human eye can distinguish things that are much thinner than the hair. Under sufficient light sources and contrast of different colors, even silk can be seen. But such a small thing has reached the limit of naked eye recognition.

A single silk is okay. If two silks are close together and there is a gap of the same thickness in the middle, the human eye will default to one.

The same principle applies to these threads in front of us. It is too thin, only about 30 times as thick as the hair.

A circle of ultra-fine threads surrounds, as it should be by rights has exceeded the human eye’s visual recognition limit, resulting in the illusion that there is no thread on the surface of this nut.

1 millimeter, in industrial processing, is often referred to as 1 wire, which is equal to 1 mm.

But now the precision of the International Five-axis Processing Center is usually 0.2 wires. The domestic precision is like 0.8 threads.

This merely theoretical data, in actual operation, if you want to reach a precision of 0.2 wires, you must adjust the machine tools to the optimal level, use laser to calibrate the tool, and the tool wear is automatically compensated.

This nut in Ye Qing’s hand has already represented the processing limit of ordinary Five-axis Processing Center.

“An eye opener, who can imagine Japan Technologies University, can make a nut like this?” Professor Cai Chenning said with some sorrow: “When we got this nut, we still have students who don’t know how to do it, mocking Japan Technologies University Even the nut and the washer are unclear. Send a washer with no thread, it is said to be a nut.”

“Someone asked me that even a commercial 5-axis center can control precision at 0.2 wires. In theory, in a laboratory, you can control precision higher. Why can’t you make a screw?”

Because this screw must be in one go, a few 100 naked eye invisible threads are processed on it.

The key is that you have to have a tool that can be tapped, not to mention that it is not available in the market, I will make a stupid thing. Making a tool that can tap a screw is much more difficult than making a screw like this.

Also, the thread of this screw or nut is too thin. If a machine machine tool cuts lightly from alloy steel, it will cut the thickness of a wire.

Will the cut piece never be a vertical metal piece, but a roll like a lollipop?

This is due to metal stress, thermal deformation, cutting angle of the tool, metal toughness, etc.

Professor Cai Chenning wonders, how does Japan Technologies University do, in a 5 mm height nut, processing produces a few hundred ultra-precision threads with only 100 wire pitch?

The most critical people’s processing thread is not deformed.

“The answer is on the metal material used for this nut.” Ye Qing gazed at the nut representing the most cutting-edge processing technology, and said softly: “Japan has made a lot of achievements in the special alloy. The ordinary metal is not resistant to high temperatures. The alloy they use The material should be able to avoid metal stress and thermal deformation.”

“I also guess that this is the case.” Professor Cai Chenning cautiously asked: “But no matter what kind of alloy is as thin as 0.2 silk, it will deform with a light touch.”

“The recipe I brought with me, I used hand-made to grind out a very thin probe to test the hardness of the thread. I thought it would deform with a light touch, but the thread of this nut is not at all.”

“It may be that the nano-level coating has increased hardness. Using plasma vapor deposition, it can be coated with a diamond grinding layer with a thickness of only a few nanometers in one layer.” Ye Qing, brought out by a group of top grade monsters, said that some are not sure. .

Professor Cai Chenning, who also knows a little about this process, has fallen into a long grin.

They cannot do any of the technology mentioned by Ye Qing.

Not only can they not be done by Zhongyun University, none of the Seiko companies that Professor Cai Chenning knows can do this.

Therefore, he called Ye Qing cheeky and invited Ye Qing to dinner.

Even the normally 2 sleeved breeze, the Principal who almost never participated in the meal, ran, staring at Ye Qing.

“Ye Ye…General, then…can you make this kind of screw?” The elegant Wang Hongnian Principal blushed at this moment. He is a typical old-school educator. When he sees students, he always stretches his face to maintain his stereotyped image of solemn.

Ye Qing is also his student. At this time, Wang Hongnian Principal, with his old face, asked Ye Qing for help. There was always a feeling that his image was completely ruined.

Especially in the case of more than a dozen students sitting on the table.

But at this moment, no one cares about the problem of Principal’s image or not.

Immediately, Zhongyun University’s face was gone. Now in the campus forum, Mechanical Engineering Department has become a national sinner. This screw can’t be done. They can’t even find the object. Are they free to care about Principal?

Everyone was staring at Ye Qing, and Ye Qing was holding his chin: “It’s easy to make screws, the key is that I am now graduated. This academic exchange meeting is all students at school.”

Simple screw making Ah!

Making screws is simple…

Wang Hongnian Principal, who summoned the wolf from Japan Technologies University, didn’t hear the following sentence at all. His head was hot and he slammed up from his chair. His expression was even more exciting than when he became Bureau of Education Chief: ” Chief Ye quickly made a screw and fiercely taught the arrogant guy.”

“Chief Ye ~ Didn’t the school send out the graduate application form when they graduated?” Professor Cai Chenning’s eyebrows were almost flying, and he was rubbing his hands excitedly.

“It seems there is…” Ye Qing of course remembers the form. Merely Ye Qing knows that she is not that piece of material. She won’t pass it if you fill it.

Professor Cai Chenning snapped a blank form on the rotary table.

“Welcome Chief Ye to come to our school as a graduate student. You are not used to take classes. If it is not that damn programming to go, it is no problem to take the Court Academecian degree directly with your professional knowledge.”
