Lao Wang has a lot of experience. At the beginning, he was just positioning.
After the traces are made, the drill bit can rotate stably, and it is confirmed that the hole can be drilled accurately, the force begins to be exerted.
In this way, the force will not be dispersed and the drill bit will not deflect, so naturally the drill bit will not be damaged.
"It's in." Lao Wang immediately shouted happily when he felt the iron filings flying.
"Hey, this thing made by this foreigner works. No wonder it's so expensive!" Cheng Daqi said happily.
"What's there to be proud of? Is this special alloy produced domestically?" Qian Wenhua said angrily.
"Bang!" Just when everyone thought everything was fine, they suddenly heard a crisp sound and the drill bit broke.
"Ah?" Lao Wang was stunned in surprise and even forgot to turn off the electric drill.
In fact, it doesn't matter whether to turn off the electric drill or not at this time.
"how so?"
Cheng Daqi obviously couldn't accept what happened suddenly.
In his subconscious, the quality of foreign products is very good, but now this performance makes him very disappointed!
"What's going on?" Qian Wenhua also looked at Lao Wang in surprise.
Lao Wang was a little stunned. He knew very well what happened just now.
It turns out that this kind of thing can only happen to some domestically produced drill bits.
The drill bit has penetrated into the steel, but it is affected by the high-strength steel and cannot drill further.
But at this time, the drill bit is still rotating at high speed, so how can the drill bit not break?
But now he is using drill bits imported from foreign countries! And it’s a tungsten alloy drill bit!
How can such a drill bit be broken?
The most important thing is that Lao Wang is very aware of the strength of this drill bit.
But the performance of the current drill was definitely not as good as the strange-looking thing in front of him.
Lao Wang also knows that the harder the material, the better the drill bit made.
But now there is a kind of steel that is harder and tougher than the drill bits they imported. This is incomprehensible.
If this kind of steel can really be produced in China, what kind of prosthetic limbs can be made? How great it would be to directly produce drill bits!
How can the alloy used to produce such a strange thing be able to produce hundreds of the drill bits he used just now? How much production value is this?
Even if it is not sold, but just replaces drill bits imported from foreign countries, how much foreign exchange can be saved every year?
"Are there any good drill bits left? Take them out and keep drilling!"
Among them, Yu Aiguo's reaction was the fastest. He immediately thought that this might be an opportunity.
Qian Wenhua's reaction was not slow: "Find some drill bits and drill in another position."
"It's best to find good drill bits. If your machine shop doesn't have them, then try to borrow a few."
Cheng Daqi looked at the old leader and then at Lao Wang.
Lao Wang smiled bitterly and said: "This drill bit was bought by a master I recognized when I went to the provincial capital machinery factory to study."
Qian Wenhua was speechless. They couldn't find the temple gate now carrying the pig's head?
No, it should be because they are poor!
"Change the drill bit to a thicker one so it won't be broken, right?"
It was Yu Aiguo who responded the fastest.
He is more interested in materials now. As for whether it can be used as a prosthetic limb, he has seen it with his own eyes before, is it still unclear?
Glancing at Qian Wenhua secretly, Yu Aiguo was a little embarrassed. He almost missed the treasure!
However, this time it was definitely an unexpected surprise. He really didn't expect that he, who prided himself on being so smart, would one day almost do something like buying a casket for a pearl.
You have eyes but don’t recognize gold and jade! Jade Aiguo was a little emotional.
However, no one looked at him with emotion at this time, but everyone's eyes were shining, because there was no fool at the scene.
Lao Wang also realized at this time that it seemed that these leaders were more interested in this kind of material.
I replaced the drill bit with a larger specification, and even replaced the electric drill and went directly to the drill press.
Clamp the prosthetic limb securely and use a drill press to drill the holes, so you won't be afraid of the drill bit being broken.
However, the domestic drill bits at this time are really not good.
Of course, drill bits of this quality will actually be available in a few decades.
But at that time, a drill bit only cost a few yuan, and the more expensive ones were only a dozen yuan.
Obviously, the price in the future cannot be compared with the current price.
It’s just that the quality is as bad as ever, so although the drill bit is very thick, it is still a bit stretched when it comes to high-quality tool steel.
Fortunately, I used a drill press this time. I could grind an iron pestle into a needle and grind it slowly, and I could actually make a hole.
Although it took a lot of time and the hole drilled was a bit big, it was drilled through in the end, but the drill bit was a bit worn.
"Without affecting the test prosthesis, select a few locations to drill holes to see if the material is the same in all places."
Qian Wenhua was already beaming with joy at this time, but he still wanted to seek more confirmation.
Open the clamp, change the position, and grind the pestle into a needle again.
At this time, everyone saw how excellent the material of the prosthetic limbs in front of them was.
"Preliminarily, the hardness is definitely very high, and the toughness should also be low,"
Lao Wang looked at the material in front of him eagerly. If there was such material, their processing factory could make their own drill bits.
Through the conversation with several leaders just now, Lao Wang also knew that this thing was made by a rural boy.
Since a rural boy can make prosthetic limbs without any professional tools, the processing performance of this steel must be very good.
A high-quality high-carbon steel that should have good workability during processing, including hot and cold working properties.
Now it seems that the tensile strength and impact toughness of this alloy steel are super strong.
Also, the strength and ductility should also be good.
With these characteristics, no matter how easy it is to process, what can they not do?
What's more, this high carbon steel obviously doesn't have tungsten treatment.
Would the performance be better if some more tungsten was added?
"Don't be anxious! Now let this brother try it out to see if this prosthesis works well."
Seeing a group of people trying to tear the prosthetic limb into pieces, Yu Aiguo was a little anxious.
"Wait a while, as long as it works well for testing, you can take it apart and play with it however you want."
Qian Wenhua glared and said, "How can you just take it apart for fun?"
Yu Aiguo smiled bitterly and said, "Even if this material is extremely good, so what?"
Qian Wenhua was stunned for a moment, and then thought of something.
Cheng Daqi didn't understand what Yu Aiguo meant. He widened his eyes and said, "Even if I don't know how to do it, I still know that this thing is useful. It is still very useful!"
Xiao Zhou was thoughtful on the other side, because he was also a smart man and had already sensed some changes in the country.
If it were the case, no matter which brother unit had any technological breakthrough, as long as the factory was willing to pay some travel expenses, they could send people to learn it.
What now? It seems to be a little different.
If ordinary people still can't feel this, leaders big and small already have a clear understanding.
Of course, if you pretend to be confused and insist on taking other people's things, that's another matter.
"Let's do the experiment first. After all, it's something that appears in China. If the meat rots in the pot, it's a good thing anyway!"
The old leader is still very aware and reacts quickly.
"Drilling?" Lao Wang next to him asked.
Qian Wenhua waved his hand and said: "Try to see if it works first. This is more important than some high-quality materials. After all, we are people-oriented!"
After unifying their opinions, Qian Wenhua was no longer anxious.
Because he knows very well that if he is oppressed based on national justice, what will he not get?
But, can it still be done now?
In the past, under this name, a large pharmacy of some kind did some very outrageous things and obtained many private secret recipes passed down from generation to generation.
But what's the final result? I heard that even the warehouse was burned down?
Regardless of whether he was really burned or not, the drug seller is making a lot of money now.
Although it is to make money for the country, is this really a good thing?
Qian Wenhua thought a little too much, because he knew very well that robbing other people's things would not last long.
Especially in the technical field, the consequences of doing so are even worse!
Not to mention other things, if people can’t make a profit by researching technology, why should they still work so hard to do research in the future?
This applies to any industry!
For example, if they snatch this special alloy, it won't bring enough benefits to the inventor. Will there be such a good thing in the future?
Maybe, but certainly not much!
Can the development of a country only rely on luck?
Obviously, this is not advisable.
So what should be done if a technology wants to be applied and developed?
This is worth thinking about, because they have now decided to reform and open up!
