Li Hao: The file they use is an ordinary double-grain file, and there is nothing special about it.

If you want to work on metal surfaces, you can't just use a file.

Finally, it is necessary to use different types of sandpaper for sanding.

But the filing step alone has already stumped many students.

The reason why Zhou Wen wanted to play was to see if his scanning eye could be of great use.

He followed the specifications in the book, held the file in his hand, placed it on the surface of the workpiece, and frustrated it in one direction according to the standard operation.

Li Hao on the side was frightened, for fear of any accidents.

After all, Zhou Wen was not a student of their Mechanical Academy, and this was the first time he had done it.

Kong Xiang clasped his arms in front of his chest, looking arrogant.

Metal surface processing may seem simple, but it is actually very difficult.

The higher the accuracy required, the more difficult it is to do.

"We use a file to file down, the most difficult thing is to ensure that the strength of each stroke is the same, a little more on one side, a little less on the other, the surface seems to be a small error, but with an instrument measurement, the error is very large. Kong Xiang said slowly on the side.

Dividing a millimeter into 100 parts, each of which is 0.01 millimeter, or ten microns, is called a wire in mechanical dimensioning, these are not normative units, but they are also traditionally said.

How much can be filed with a file, the students don't know how much they can file.

But after all, it's just an internship in the workshop, not really processing the workpiece, and everyone doesn't care about the accuracy, as long as it's about the same.

But Zhou Wen is different, what he wants to challenge is mirror processing, which is difficult.

At the very least, the surface must be smoothed first.

"Sting!"

Zhou Wen filed a file, and some iron filings could be seen falling on the vise.

At this time, Zhou Wen's movements stopped, squatted down, put his eyes and the surface of the workpiece on a horizontal line, and looked at the workpiece intently.

The patterns in his field of vision are completely different from the others.

The small unevenness on the surface was extremely obvious to his eyes, and every trace would not be missed.

Zhou Wen carefully observed every scratch, and he needed to find a suitable point to continue to frustrate.

At this time, a voice suddenly sounded in his ears.

"The wearer is already familiar with the basic functions of the Scanning Eye, and the Scanning Eye function will soon be fully activated. ”

The pleasant voice sounded again, and Zhou Wen was stunned for a moment.

Are there any other features that aren't turned on?

At this moment, a string of numbers suddenly appeared in Zhou Wen's sight.

The numbers hung next to some of the objects, following his gaze.

A line of numbers also appears on the workpiece clamped by the vise.

"It is 70mm long, 15mm wide and 15mm high. ”

"!" Zhou Wen suddenly exclaimed.

He never expected that the value could still be displayed.

"President, what's wrong with you?" Li Hao hurriedly asked.

Zhou Wen turned his head to see that there was also a string of numbers hanging beside Li Hao.

"175cm tall. ”

Everyone has a height value around them.

"I didn't find out that there was this function before?" Zhou Wen wondered in his heart.

Height is his first impression of everyone, and if he can see all the heights, he should be able to see some other values as well.

Zhou Wen's heart moved, and in his field of vision, all these numbers disappeared.

He wasn't interested in paying attention to other people's heights every day.

Zhou Wen immediately looked at the workpiece in the vice, he wanted to make an attempt.

Turn on the microscopy function to magnify the surface of the workpiece.

When viewed from the side, you can see the unevenness of the surface of the workpiece.

These are like mountains.

Zhou Wen's heart moved, and suddenly, numbers appeared on these mountains.

"Height 0.57mm, Height 0.34mm, Height 0.66mm......"

Looking at this scene, Zhou Wen's heart was full of surprise.

Without measuring, he can measure the length with his naked eye!

This is the eye of scanning!

Scanning, how can it be called scanning without data.

Zhou Wen directly took out the file and filed it downward.

Theoretically, the surface error of this workpiece is so large that it can be said to be scrapped, but Zhou Wen feels that it can still be rescued.

One, two, three......

Under Zhou Wen's slow operation, the surface of the workpiece became flat at a speed visible to the naked eye.

The students on the side all looked at this scene in amazement.

Outside the workshop, Liu Wenping walked in with a teacup in his hand.

"What's going on?" Liu Wenping wondered.

"Teacher Liu, Zhou Wen said that he wanted to try polishing the hammer head, so I asked him to give it a try. Li Hao hurriedly said.

Hearing this, Liu Wenping's eyes suddenly lit up.

He wanted Zhou Wen to come to the Machinery Institute before, but this kid was unwilling, but now he is actually interested and takes the initiative to polish the workpiece.

"Teacher Liu, Zhou Wen just said that he wants to challenge mirror processing!" Kong Xiang's voice suddenly sounded.

Liu Wenping's expression was stunned for a moment, and he almost scolded directly.

Mirror finishing, are you kidding?

He hurriedly turned his head to look over.

At this moment, Zhou Wen concentrated on grinding the surface of the workpiece with a file.

"Mr. Liu, he's been polishing for a long time, and he hasn't even done this one, and he still wants to process the mirror, isn't it just wishful thinking!" Kong Xiang sneered.

Metal surface processing, mirror surface is the most ideal state.

The smaller the error, the longer the life of the workpiece.

When it comes to machinery, precision is important.

"Shut up!" Liu Wenping suddenly scolded.

Kong Xiang's face froze, and he couldn't figure out why Liu Wenping reprimanded him.

At this moment, Liu Wenping bent down slightly, his two eyes stared at the boss, staring at Zhou Wen's hands.

The file moves over the surface of the workpiece one by one, bringing up iron filings with each blow.

At first, I didn't think there was anything when I saw Liu Wenping, but it was just an ordinary usage.

But on closer inspection, Liu Wenping almost scared out of heart disease.

The strength of each of Zhou Wen's knives is exactly the same, and the thickness of each file is just right, no more and no less.

Those students can't see it, how can Liu Wenping, who has been in the workshop for more than ten years, not see it!

"Teacher Liu, do you think he can do it?" Li Hao said curiously.

Zhou Wen's appearance looks like that.

"This is the master...... Liu Wenping sighed.

"What?" Kong Xiang was dumbfounded, "What master?"

Liu Wenping shook his head helplessly and said: "Students, although I have always told you that hard work can change a lot, it is undeniable that talent does exist. ”

"Don't look at Zhou Wen just grinding on the surface, but in fact, every one of his knives is extremely accurate, and it is no worse than a machine. Liu Wenping continued.

"It's not bad compared to a machine, teacher, are you kidding?" Kong Xiang said in disbelief.

He was already the best performer among the crowd, and now there was an economics school with better talent than him, and he felt very uncomfortable.

"Nothing is impossible, you should know that machine tools are produced by industrial machine tools, so what is the production of machine tools?" Liu Wen said slowly.

Industrial machine tools are the equipment used to produce machine tools, which is the symbol of an industrial manufacturing power.

In the past, when there was no equipment, the parts of the mother machine could only be made by workers.

People can do a lot more powerful things than machines, but they are inefficient.

The machine is capable of mass production.

Many students were all shocked by Liu Wenping's words, is Zhou Wen really that powerful?

At this time, Zhou Wen in front of the vise let out a sigh of relief and said, "Finally filed this side." ”

Everyone hurriedly turned their heads to look, only to see that the workpiece, which could be seen with the naked eye, had become extremely smooth on one side.

It's just a file, but that's it, it's better than what they sanded with sandpaper.

Zhou Wen kept moving, continued to turn the workpiece over, and continued to process.

Every knife is extremely precise.

Zhou Wen's movements are also extremely standardized, which is pleasing to the eye.

Liu Wenping and a group of students all gathered around to watch.

Outside the workshop, a student who looked a little older walked in.

He saw a group of teachers and students all standing motionless next to him, with puzzled expressions, and cautiously walked in, and also stood aside and watched.

After processing a noodle, Zhou Wen immediately changed the noodle.

The six sides were processed in no time.

With the eyes of scanning and the hands as steady as a dog, processing these is not a problem for Zhou Wen at all.

"That's too fast, isn't it?" said the student who came in at the end.

Hearing the voice, Liu Wenping turned his head to look over.

"Wang Zhao, why are you here?" Liu Wenping wondered.

"Mr. Liu, we are doing experiments over there, but the guide rail of the lathe is broken, I want you to go over and take a look. Wang Zhao pleaded.

"Okay, I see, we'll get over later. Liu Wenping nodded.

Wang Zhao is a graduate student of the Institute of Mechanical Engineering, and he is using the lathe in the training building to process a workpiece, which he designed himself.

"Teacher Liu, who is this person, seeing that his technique is so stable, you can transfer him to my research room. Wang Zhao said with a flattering smile.

"Students of the Faculty of Economics, I can't move. Liu Wenping shook his head.

Wang Zhao was dumbfounded: "Students from the School of Economics?"

Should you be so good as an economics student?

At this time, Zhou Wen had already taken out the sandpaper and began to polish it.

He carefully sanded it with sandpaper, and each stroke was very steady.

First coarse grinding, then medium grinding, and finally fine grinding.

The last step is to polish the mirror surface.

With Zhou Wen's movements, a mirror-like surface appeared on the original dull workpiece, reflecting the light.

The mirror surface is like a mirror, which can reflect the scene.

The students around were all stunned, and they were actually made by him.

Among these people, Kong Xiang's face was the most ugly.

"That's it!" At the end of the last session, Zhou Wen put down the sandpaper, wiped the entire surface with a soft flannel cloth, and put it on the workbench.

The workpiece is boxy, and the surface reflects the surrounding scene.

If someone says that it is not mechanical polishing, but manual polishing, it is really hard to believe.

"I don't believe it! I'm going to measure!" Kong Xiang shouted.
