"This is a bearing billet with a radius of two centimeters, and the error should be within two millimeters...... Chen Tong, you are the first place in the Fucheng Lathe Competition last year, come, you come to give me a finished product to see!"

Chen Wei pointed to one of the more than thirty workers in front of him and shouted.

The worker, Chen Tong, was about twenty-seven or eighteen years old, about the same age as Chen Wei, and he walked to a lathe with confidence, skillfully put on protective gear, and started the machinery to work.

More than ten minutes later, a bearing was cared out.

"Teacher Chen, I'm done!"

"Okay, Song Peng, you can test it!"

"Mr. Chen, the error of this part is 1.5 millimeters, which meets the standard of 10%!"

Other people heard this value showed a look of envy, they are all lathes, can reach 10% of the specified error is already good, the other party has increased 0.5 millimeters, this is the master level, don't underestimate this trace of improvement, that is enough to affect the life of a machine tool, is very remarkable.

"Come here, watch me work, remember, write down my skills at all!"

After Chen Wei finished speaking, he put on protective gear and walked to the same machine tool to work.

Everyone watched intently, Chen Wei's techniques were very different, but the speed was faster, and a finished product was completed in less than five minutes.

"Test it!"

Chen Wei pointed.

"What? The error is only 0.8 millimeters? How is it possible?"

This value frightened everyone, to know that these equipment are the original equipment of the bearing factory, have been used for almost 30 years, the whole Fucheng to do bearings are used this equipment, so many years no one has ever been able to reduce the error to less than five percent, such a part is completely in line with the standards of the new generation of equipment manufacturing, that is to say, if the bearing factory can manufacture this precision bearing, then it will not go out of business, and will not be acquired by Liu Lang in the form of a special enterprise.

Now that Chen Wei has done it, if he is a master with decades of experience, everyone can still accept it, but the age of the person is younger than many people, is it just because he is a top student of Huaxia Industrial Technology?

"Are you surprised? Why can I make the same device with such high accuracy? Do you know why?"

Chen Wei asked.

"Teacher Chen, because you are a college student! You are still a top student of Huaxia University, we can't compare!"

One replied with a shake of his head.

"What's wrong with college students? College students are also human beings, and they have one head and two hands, do I have one more hand than you? That's three hands, and the police will arrest me!"

"Three hands" is the name of the common people for the thief, everyone laughed when they heard it, although the other party is a college student, but he also speaks "rudely" at work, and everyone thinks that he is their "kind".

"Let me tell you, this is the craft, what is the craft? To put it bluntly, it is your own ability, which allows you to bring out the limits of the machine, do you want to have such a skill?"

"I think, of course I think about it, I think about it in my dreams!"

The crowd shouted.

"Okay, then you have to study hard, in fact, this is very simple, it is a tangential process, and this process was invented by Liu Lang and Mr. Liu!"

"What? Mr. Liu again?"

Everyone was shocked again, but they quickly recovered, since they came to work in North Industries Group, almost all the knowledge they learned every day was related to Liu Lang, not to mention Chen Wei, even in Professor Xiong's mouth, this child is also an omnipotent immortal.

"Okay, don't be stunned, today I will tell you the essence of the tangential process, you have to learn hard, if you don't learn well, then give me fifty bearings to ......... today!"

In another workshop, an engineer from Huaxia Industrial Technology Co., Ltd. named Du Xin is giving a lesson to a group of welders.

"Let me ask you a question, I use the same material to make two doors, one of which is smaller, because it is made of a single piece of material, and the other door is made of two pieces of material welded together, then I ask, which of these two doors is stronger?"

"Teacher Du, of course it's the first door!"

One person asked.

"What do you say?"

Duhin smiled and looked at the others.

"That's right!

"I know your reasons, I think that the integrity of a complete material is of course better than the welded material, just like sewing clothes, if the clothes are broken, no matter how good you sew, it can't be compared with the original good clothes......... However, I tell you that this idea is wrong, the real welding technology is not splicing, but a way to improve the original strength, if you don't believe it, today I will show you ......!"

"This is a metal material strength tester bought by Mr. Liu from the United States, which can test the stress, tensile, toughness and other indicators of the pipe, there are two kinds of pipe fittings here, one is forged by a 1,000-ton hydraulic press, the diameter is 30 centimeters, let's take a look!"

Everyone looked at it, as welders, of course, they knew whether the pipes had been welded, which was the most common kind of iron pipes with a length of 50 centimeters and a diameter of 30 centimeters.

"These are two identical iron pipes, but I'm going to weld them together now, you see!"

After Du Xin finished speaking, he picked up the welding tools after putting on the protective gear and started working, which immediately attracted everyone's attention.

They are all workers with several years of welding experience, although they are not masters, but there are also long-established "masters" among the masters, what "pressure vessel factory first welding", what "hydraulic parts factory old welding king", these old workers have absolutely unique technology, but compared with Du Xin, who is also thirty years old, it seems to be a little inferior, all kinds of difficult welding methods at hand.

Du Xin's welding techniques are varied, what vertical welding, direct welding, twist welding, all kinds of techniques to make everyone dizzy, less than ten minutes, two iron pipes were welded together.

"What a speed!"

Everyone was secretly amazed.

This kind of iron pipe is the most ordinary cast iron, and the iron pipe is not large, but if you change it to welding it yourself, it will take fifteen minutes.

Although everyone still hasn't understood what the purpose of this Teacher Du is, with this method, I'm afraid there will be no second person in Fucheng.

"Okay, now let's do a destructive experiment, that is, tear this iron pipe apart, and then everyone will see what you think, Xiao Sun, you can help!"

The two men put a 70-centimeter-long iron pipe into the metal material measuring instrument, and then carried out a completely sealed treatment, and after turning on the switch, everyone retreated to the side of the digital display screen.

Various numbers were constantly displayed on the screen, and Dushin explained to everyone.

"It's the pressure, it's the pressure on the internal pipe, and the pressure limit of the pipe......... Look, the iron pipe is almost at the limit of pressure!"

That is, in ten minutes, there was a "bang" sound in the pressure chamber, the sound was very small, but everyone heard it clearly, obviously the iron pipe was broken by hydraulic oil.

Of course, these people have encountered this phenomenon in their respective factories, the pressure of the hydraulic press is too large or the welding is not done well, and the iron pipe is sometimes no different from the piece of paper under the powerful hydraulic press, they are not surprised, but they really haven't seen this kind of instrument that can display various parameters, and they have never even heard of it, it is simply a magical instrument.
