This thread can only be filed little by little.

However, these are not difficult things for Zhou Wen at all.

Liu Wenping took out a few pieces of special tool steel and threw them to Zhou Wen.

The two of them started working in the workshop.

There is no CNC machine tool in the workshop that can process this accuracy, and everything is a last resort.

Thinking back to the time when a group of people knocked out nuclear weapons with an abacus on the desert desert, this difficulty is nothing.

For lunch, Wang Zhao sent the boxed lunch bought from the canteen, and several people dealt with the meal directly in the workshop.

During the whole processing process, Liu Wenping became more and more frightened the more he watched.

If he didn't know that Zhou Wen was a person, he would have thought that Zhou Wen was a highly intelligent robot sent by some country.

Zhou Wen's eyes and hands are like machines.

Usually he has to use the instrument to measure the size, and Zhou Wen directly reports the number.

The accuracy of the vernier caliper is 01, the accuracy of the spiral micrometer and micrometer is 001, and the accuracy of the dial gauge is 0001.

The laser ratio meter can be accurate to 00002 at a constant temperature.

The smaller the accuracy of the measurement, the greater the environmental requirements.

temperature, which affects the size of the object.

But none of this is a problem for Zhou Wen.

As long as he can see it, he can see the dimensional data.

"Old Xue, it will take a while, you go back to rest first. Zhou Wen said slowly.

He's got the hang of it, and that's all that's left for the final processing.

"Out of the way, I'm going to see you do it with my own eyes. Xue Lao said slowly, his expression was very haggard.

"Old Xue, you are too old to stay up, just stay here with Zhou Wen and I. Liu Wenping hurriedly persuaded.

Xue Lao is seventy years old, and if there is an accident if he stays here, everyone can't afford it.

"Teacher Liu, I mean you should go back too, I'll just stay here alone. Zhou Wen said sincerely.

The processing methods that should be mastered have been mastered, and it is useless for these teachers to stay here, so it is better to go back and rest.

These people are not comparable to Zhou Wen's energy and physical strength.

Not to mention the bonus of the superhuman robe, just the few body-strengthening pills he ate before, Zhou Wen's current physical fitness is not comparable to ordinary people.

"Are you going to do it alone?" Liu Wenping wondered.

"Teacher Liu, I can only do this processing alone, you can't help, you just have a good rest, just wait for my good news tomorrow morning." Zhou Wen said with a smile.

Wang Zhao on the side said: "I'll stay here, I'll go back to the dormitory." ”

"Okay, you and Zhou Wen together, I'll send Xue Lao home first. Liu Wenping nodded.

It's nighttime now, and it's already dark.

It's easy to have an accident if you go back later.

"Old Xue, Teacher Liu walks slowly. Zhou Wen said with a smile.

A smile appeared on Old Xue's haggard face, and he stretched out his hand and patted Zhou Wen's shoulder.

"Zhou Wen, I can meet an excellent student like you in my life, and it is not in vain that I have come here all my life, I know that your ambition is not in machining, but I still hope that you can go a little in the direction of scientific research. Xue Lao said earnestly.

"Science and technology are the primary productive forces, this sentence has never been wrong, the so-called economy and finance ultimately have to rely on the development of science and technology. ”

"From the first industrial revolution to the present hundreds of years, it is the fastest period of development of the entire human society, and the speed of development will be even faster in the future. ”

"Science and technology represent the hard power of the country, and if science and technology are strong, our fists will be harder, and we will not be bullied in the international community. ”

"I know that many students in the School of Economics feel that we don't make money and don't want to come to the School of Mechanical Engineering, and many students in our School do not choose to pursue this industry after graduation. ”

"But I believe that our scientific research life will get better and better in the future. ”

"Every truth is like a star in the night sky, and when we reach out and pluck the star, even the whole universe trembles. ”

After Xue Lao finished speaking, he turned around and walked outside.

These words were said by him from the bottom of his heart, no matter how much Zhou Wen could listen to them.

If you say it, Xue Lao will not regret it.

When Xue Lao left, Zhou Wen still stood in place and did not move for a long time.

His eyes were thoughtful, as if he was thinking about Xue Lao's words.

Wang Zhao on the side sighed and said: "Our life is getting better and better now, it is the people from generation to generation who have worked hard with their blood, Xue Lao and he ......."

"I understand. Zhou Wen said slowly.

He didn't understand these scientists before, but he seemed to understand something now.

On the path of science, there is no profit and harmony, there is only the pursuit of truth.

On this road, scientists have gained far more spiritually than ordinary people imagine.

This life is in vain......

"Work hard, we'll get this done tonight. Zhou Wen said in a deep voice.

"Okay!" Wang Zhao nodded.

On the workbench, the workpiece is already placed.

The rudimentary shape of a screw is machined with a machine tool.

The length of the thread is 10 mm, and the exterior is all covered with threads, and one side is an inner hexagon for easy screwing with tools.

But this screw does not have a cover, so this hexagon should also be engraved on the inside of the screw.

However, this is not difficult, and it can be processed directly with a lathe.

The most difficult thing is the thread on it, which can only be carved out little by little.

Zhou Wen held a very small knife in his hand and moved on the screw, carving out the threads little by little.

The slightest mistake in this will be nullified.

High temperatures are generated during the machining process, which causes the threads to deform, so gas is used to cool down the threads to prevent deformation.

At two o'clock in the middle of the night, Wang Zhao was already asleep on another workbench, and Zhou Wen was still working.

He was holding a non-standard screw in his hand, and his face was joyful.

"It's finally done!" Zhou Wen said excitedly.

After several mistakes, Zhou Wen finally made a screw.

He now had a faint feeling that if he had a whole set of tools in his hand, he could file everything by hand.

"This one is still a little flawed, but it doesn't affect the use, I'll make another one. Zhou Wen said secretly in his heart.

Without making too much noise, so as not to wake up Wang Zhao, Zhou Wen picked up the excess workpiece on the side and continued to process.

This time it's even faster, and in an hour, a screw has been formed.

"It's a little better, but it's still not perfect, and I could be more accurate. Zhou Wen frowned and commented in his heart.

Picking up a workpiece again, Zhou Wen got careful this time, and after half an hour, all the threads were done.

"Haha! This is perfect!" Zhou Wen looked at the screws in his hand, his face full of joy.

All three screws could be used, but the one he made in the end was more perfect.

More accurate than the original thread!

Zhou Wen carefully picked up the three screws, went out the door, and walked into another laboratory.

There is an instrument in this laboratory that coats the workpiece.

Huhai University is a little worse in high-precision metal processing, but it is strong in nanotechnology.

This instrument can plate another material on the workpiece with nanometer precision, and more importantly, this equipment is domestic.

After processing, Zhou Wen held three screws in his hand and breathed a sigh of relief.

The screw looks dull, like a matte surface, because of the material covering.

With the naked eye, the threads on it are not visible.

Zhou Wen returned to the workshop with the screws, saw that the time was still early, and quietly ran to the original lathe.

I also have to help get the guide rail, I haven't finished it yet, and I just have nothing to do now, so I just cleaned up the guide rail together.

......

At six o'clock in the morning, Wang Zhao woke up sleepy-eyed and saw that the side was empty, and there were three made screws on the workbench.

"Damn, the screws are ready!" Wang Zhao shouted excitedly.

"Zhou Wen, Zhou Wen!" Wang Zhao hurriedly shouted.

However, Zhou Wen is no longer here.

Zhou Wen is sitting in front of the workbench in the workshop of the original flexible shaft machine at the moment, carrying out the final carving of the jade bracelet.

His subordinates, the appearance of a hollowed-out ring phoenix jade bracelet has appeared.

The white jade phoenix pattern surrounds a circle, connected from end to end, and is extremely exquisite.

Each pattern is reflected in the depth of the carving, and the feathers and scales can be clearly seen not only from any angle.

There was also a jade pendant on the table.

Hollow carved dragon play phoenix jade pendant.

A dragon and a phoenix are separated from each other, surrounded by a bead, with distinct scales and lifelike, reflecting light.

The ring made for Zhu Xialan has also been made.

This ring is even more difficult, and it is just a few maple leaves carved in hollow.

Zhou Wenwen was just carved briefly, but later with the Scanning Eye, he opened it directly, carving every blade of the maple leaf as if it were real.

If you look at it with a magnifying glass, you can see the texture on the leaves.

As Zhou Wen put down the last stroke, the entire jade bracelet was completed.

"It's finally done!" Zhou Wen let out a sigh.

Not only did it exceed expectations, but it also achieved its goals ahead of schedule.

Taking out the box prepared in advance, Zhou Wen put the jade bracelet and jade pendant into the box together.

Zhu Xialan's ring was packed in another small box.

Hetian mutton fat white jade ring, coupled with this process, this ring sells for hundreds of thousands, which is much more precious than those diamonds.

After cleaning up the workbench and putting everything into the box, Zhou Wen walked out of the workshop with the toolbox.

If nothing else, this will be his last time here.

Although he didn't stay for a long time, Zhou Wen liked the environment very much.

"Come back when you have a chance. Zhou Wen smiled and walked out of the workshop.

......

In the hotel, Haruto Yamaguchi was kneeling on the ground and eating breakfast.

"What? You said Huhai University said that the screws were made?" Haruto Yamaguchi said in surprise as he picked up the phone.

"Okay, I'm afraid they won't be able to do it, but now that they've made it, I'm going to go and see it!" Haruto Yamaguchi laughed.

He didn't believe that Huhai University could make this screw at all.

As for the screws that are made now, they must also be something that cannot be used.

High-precision processing, Dongying is not weaker than any country!

Harukoto Yamaguchi has this self-confidence.

After breakfast, Haruto Yamaguchi changed into a Toei costume and slowly walked out of the room.

In the other rooms, several people dressed in Dongying costumes also walked out one after another and followed him.
