Fizemos a BOLA PERFEITA de NIÓBIO!

and today we are going to make the perfect ball with niobium. And then this ball is going to be great because we are going to use one that is even more special than niobium, in a while you will understand why, but it is also going to be a different method than ever before. The perfect balls that we have already made we will use a metal lathe, but to begin with, what is this niobium? Niobium is a metal that has many applications, some people think that it is rare and only exists in Brazil. But this is not true, the minerals that are used to produce niobium exist in more than 85 places spread across all continents, but here in Brazil has mastered niobium technology so much that we are the largest niobium producers in the world, including us.

We did it, although we saw it in Araxá in Minas Gerais, where CBMM is mentally produced, which is a leading company in the segment, it was from there that we brought these beauties, here there are people who think that it is a stone, a mineral that we already extracted the niobium of the earth like this, but the reality is that this is niobium, it is a metallic alloy that to everyone's surprise, in aluminum with niobium, appears in iron, with the obvious, this Here is one of the main products to niobium base. What is it used for in industry?

It is added to steel as a kind of seasoning. And then the steel becomes more malleable and stronger, but for our industry Perfect Ball here. manual is not entirely like that, look what happens if I try to make a mistake with a piece of iron-niobium put in and nothing, the truth is that this material here is very hard because we are trying to do it, we spoke with cbmm and they sent this beautiful billet Obviously metallic, simply the material purer that you have to produce within it our perfect ball is all about removing the excess and it is the principle of the metal lathe and similar to that wood lathe that we already use in the manual of the world the The difference here, this here is absurdly more Precisely, what we are going to do is clamp that niobium billet here in this Chestnut and what will remove the niobium from the piece, right?

What will it reveal? Wow, what's already inside is this tool here? the tip, we have a hard metal that will crush the niobium And when the piece rotates to control this rotation and make a perfect ball is that we have a template to copy the template, there are two cars here, so we will have to look at the draw and move these two cranks, this one will control this movement from here to there and this one here is the depth so in the end it's going to be a manual job and if we make a mistake when copying the template a somewhat oval ball may come out But that won't happen Relax, watch the movement What this needle will do on top of the drawing, is exactly the same movement as making land in front and And in this case I hope it is not that type of movement that.

What happened with the microphone is now like this and I'm going to place the niobium cylinder as you may have imagined, one was exactly centered. I need help here using the dial indicator to make the part as accurate as possible. After the other side we will make a hole in the center, this is important to be able to hold the pieces on both sides and now the machining begins to make sure that this type of milk that falls on top is an oil that is used for refrigeration, so we have the possibility of ruin. the tip of the tool.

And then this is the first thing that will be machined here. It is not exactly the ball, it is a handle, a support so that we can hold the cylinder in another way. When we are going to make a ball, we cannot learn from this large part, we have to put something small in it, which is what will remain after grandma has made it and this coiled worm that is coming out, so this leftover is called a chip. Now we are going to start polishing more or less giving it the shape of the ball without much care, which is more to remove the material, although we are not even going to use the template, it is a good time to start training here. on the lathe because there is not much commitment, so they explained to me that you have to watch the chip all the time so that it always comes out the same width.

If I remove too much chip here I can cause a defect. on the ball or ruin the lathe. Looking from the outside we think it's cold but this process is very hot at the point where the tool touches the niobium it is hundreds of degrees, look what happens when we pour a little oil on top. It's time to turn it on its side and now you will understand that the handle we are talking about is a kind of Lollipop handle that we are using here now we are going to punish ourselves a little but it is also time to place the template.

At first we can't even follow the template because there is still a lot of material to remove but we are already starting to give it a spherical shape and we arrived here at 10 in the morning it is already five in the morning in the afternoon EA put it at this stage we will have to continue tomorrow and And then and you might get the impression that this right here is I'm peeling a carrot and it's a knife in butter, but it's not, you see, it's softer than niobium car, but it's still a metal difficult to teach, used in very rare and very specific things like MRI machines, particle accelerators, rockets, space probes, 1 What's up?

What's happening? What can you do something there? And then and I thought this here is a little light, it's not, it's not and I still need to remove this pallet cart up here. I know it's clear that I'm not doing everything alone, right? Whoever planned what the onion looks like, what tool I use, how were you going to do everything on the lathe? He was the messenger, he was also the one who did everything right on the ball, I just did some scribbling as I went. How many years have you been working at Contour 49? years, so Ten Years Before I was born I was already working Contouring, do you think that if I practice another 15 years I can make a ball on my own like this, can you do it as a dedicated student?

And then it's not easy, no grinder suffers, right? I thought it had a lathe, we were chipped, but no, if the material is hard, then it's easy to put the batteries in, whatever it is, look, it's already jingling, the water is hot, eh, and I'll stay until the end because This is going to be the most beautiful yet geometrically perfect and most expensive hot ball we've ever done in my serious number. Look, I swear he has a belly button. the ball we just made and it's a little silly, right, and a mirrored navel, let's take this thing over there, whoever looks at it, without a doubt, one of the best manual balls in the world, can even use it as a cannonball and finally after 3 days you will see this neon ball, but keep in mind that this will not be the only different thing you will see of this stuff out there, send me a message and you told me that not even a man is using lithium. ion batteries for electric vehicles, the idea that these batteries can be charged ultra-fast in less than 10 minutes and this is just one example of the big changes that can be seen with new materials and the work is still very recent, there are still a lot to discover, let's agree, if this is not worth a thumbs up, I don't know what a thumbs up is and if you want to know how niobium is produced from the moment it goes into the ground until it becomes a real job Check out what we did there in Araxá, it's great
