oh yes it does, what do you think that link is?
Great with no music! 🙂
👍👍
Thanks for watching!
No ear plugs either
No Music and funny Subtitles. Best Channel
Thanks a lot!
Thank you again FM!
No music, nice and relaxing. Love it!
Thank you for enjoying my video as always ;)
Yesterday I wondered why saw blades cost so much. Now I wonder how they can cost so little.
Скажем спасибо массовому производству!
This not a saw @$$ hole , these are diamond blades and expensive because have diamond
@@yashar4086Bort is not nearly as expensive as gem grade diamonds. The process is what makes the expense.
@@yashar4086 lol bro these are definitely saw blades. please relax.

great video, but one correction…the welding process is brazing, not welding.
Those fibre lasers they use for engraving are so cool.
This is very labor intensive. No wonder that they cost so much. Thanks
Just automate these simple tasks like painting, etc
Great production and editing, and even better with no music! Thanks for making the videos
Another great video. Thankyou. 👍
Thanks for watching! ;)
This is the most interesting video I’ve seen here. I had no idea what goes into making diamond cutting tools but I have a pretty good idea now. And those grinders sure take a beating! Great job.
Mohs hardness 9 grinding wheel (aluminum oxide / corundum) against Mohs hardness 10 material - diamond. They don't want to use a diamond grinding wheel because it will cut the diamonds. They want the diamonds to protrude from the carrier matrix - which is some sort of carbide (e.g. tungsten carbide). The oven process used to make the carbide is called sintering.
@@fredinit Thank you! This is really interesting stuff. I know the old saying, cut diamond with diamonds, but as you know that is not the only consideration. I’d like to know more about the diamond powder that is referenced in the video. I figure its composition is a fraction actual diamond and something else like an oxide that behaves like a flux. For sintering as you describe. I’d also like to know how they crush the diamonds to the size they prefer for this powder. Neat stuff!
Gotta love that high tech counter on the press! "nothing more permanent than a temporary solution that works."
And… splitting hairs here, but those cutting tips are brazed on, not welded.
I was going to say the same thing. 😊
I think he'd appreciate the feedback.
That difference may not exist in Korean, in many languages it's just different types of soldering for everything, you just specify wich type of solder, like TIG soldering, brass soldering, tin soldering, laser soldering, friction soldering and so on.
That may be so… but the English subtitles end up being incorrect. For anyone not hip to the lingo, brazing (or hard soldering) is the act of heating two objects, then using a filler material to join them (think: glue). Welding is the act of bringing one or more objects to the point of being molten then with or without filler they are joined by the fusion of those materials.
Not everyone has English as their first language.
my instinct was that this was a mostly automated process all done by machines, but there is so much more manual work involved. great video as usual
I'm amazed that most steps in the process are completed by hand instead of machine.
amazing process and super amazingly filmed !
This is like homemade or small factory, but they can produce such a quality item, great!

As long as it’s not China I’m glad to support. Korea and Taiwan make great tools.
China can manufacture to any standard. You just don't want to pay for it.
@@ShainAndrews No, I don't want to send my money to an aggressive regime that pays no heed to international law.
Me too.
@@rovert1284 Very true.
@@ShainAndrews I just hate China and all the stealing and aggression.. thats why i dont buy from China.. if possible

Another interesting and well produced video! Thank you for sharing!
It is nice diamonds have some practical use and not just blingbling.

Great video, and many thanks for the written subtitles 👏👏👏
ALL good. Made in Korea, the GOOD part! Thanks!
Good that you show literally how they are made, and not just an assembly line like everyone else does.
Very nice!
impressive, the diamond it self is just a compressed powder, i wonder how this arrange at molecular level to form such a solid.

That "diamond powder" looks more like a mixture of diamond powder and the metal (brass? bronze?) which is going to hold it together, i.e. act as a matrix for diamond grit. Also, this "baking" is probably called "sintering" in the trade... ;-)
That's so great
Cheers 👍💪✌
Thanks for watching!
I used to have my own concrete cutting business so I knew what goes into making the blades. But I am VERY impressed with the grinding wheels, they mush have a high diamond content to be able to grind diamond blades. I still have a segment out of an old diamond drill which I use to reshape/reface the grinding wheels in my workshop. Put a diamond onto a normal grinding wheel and the grinding wheel disapairs.
I have a lot more respect for expensive cutting tools now. Quality not expensive.
Danke.
Can you imagine, diamond dust everywhere?
Just glanced at your subscriber count... Wow. I've been with you since early 2022. I remember a few thousand followers back then. Well done!

There's probably some pakistani guys sitting on the ground with bare feet and mininal tools making discs just like this in some back-alley sweatshop.

I was using a diamond blade 10 minutes ago. Always wondered how you get dusmonds to stick to steel!
Thank you for filming this.
Thanks for watching!
That "diamond powder" looks more like a mixture of diamond powder and the metal (brass? bronze?) fillings, and this metal is going to hold it together, i.e. act as a matrix for diamond grit. It's the same as with "carbide tips" (saw tips or cutting inserts) - tungsten carbide (WC) or titanium carbide (TiC) are too brittle by themselves (and probably next to impossible to form into some definite shape alone), so they are always used within more elastic matrix - typically cobalt and vanadium (AFAIR).
а где автоматизация ? Стоит чел подсовывает руками .....
Она в будущей пятилетке...
hey like it nice and inefficient
Korea makes nice things. South that is.
*终于知道了。❤️*
2:40 i love that little arm
made in korea?
the supreme leader made these?!?
Assalamualaikum. !!
0:50 I wonder how many fingers that machine has taken off over the years... I can't believe how manual this process is for this particular blade.
Very interesting! Isn't that brazing?

Where did the fluting come from on the cutting edge? They were not these after coming out of the presses and there was no more pressing done afterwards, only baking. I love the paint they used.
All types are interesting and I have no favourite.
Thanks for this video, were can we buy these disks? Kind regards from the Netherlands
ну и чем это лучше пакистанцев? только что в перчатках и респираторах.
Well, I guess the workers won't die as young.
Thats a lot of ‘Hands -on’ work

I use industrial diamonds for dressing grinding wheels.
Do you need to go through a state permit process or pay to get into these factories?
Супер
:)
As in, blades that cut through actual diamonds?😮
Interesting and somehow impressive, but I see a lot of space for additional automation. This whole manufacturing process could be automated to the point where you put raw materials at the beginning of production line and take boxes ready to be shipped on the other side. I guess it is not automated because work of these people is cheaper than all the required equipment.
c'est dingue j'utilise des disques diamant dans le bâtiment il faut que le disque soit parfaitement droit quand tu coupe
10000 rpm minutes t'aimerais pas voire le disque voilé merci de faire du bon taf
10:30 I've always liked the idea that you can just press dry materials together and mostly make them into something. How are the abrasive wheels made?
Same method... roughly. Pseudo sintering with the addition of epoxy bonding agents.

a grinder to grind the diamond grinding tool
individually created
Really impressive. I didn't realise diamond powder could be compressed like that, I didn't think it would get hard or did you not show the firing of the blades?. What sort of grinding wheel do you use for grinding diamonds?
That "diamond powder" looks more like a mixture of diamond powder and the metal (brass? bronze?) fillings, and this metal is going to hold it together, i.e. act as a matrix for diamond grit. It's the same as with "carbide tips" (saw tips or cutting inserts) - tungsten carbide (WC) or titanium carbide (TiC) are too brittle by themselves (and probably next to impossible to form into some definite shape alone), so they are always used within more elastic matrix - typically cobalt and vanadium (AFAIR), hence different classes of inserts, dedicated to various materials (hard/ soft) and types of cut (continuous or interrupted).
And then there are ceramic inserts, polycrystalline diamond inserts and cubic boron nitride inserts, but they are totally different animals (and pricey as hell too).
Abrasive discs for bench grinders use (typically) a ceramic matrix, while these for angle grinders are phenol-resin bonded (hence the funny smell when cutting steel with them).
Also, this "baking" is probably called "sintering" in the trade. In a nutshell, you just heat the mixture to the "below melting point" temperature.
PS: At 13:43 you can see individual diamond grains - these tiny black "pimples" are diamonds, all the rest is just a matrix holding them in place.
When an individual diamond piece gets too dull, the forces acting on it (while cutting whatever it has to be cut) become stronger than adhesion forces holding it in the matrix, and the grain falls off, and the matrix quickly wears off until new piece of diamond "comes out" - and so da capo al fine.
However, when the material being cut is too soft there may be to little force to actually force that blunted grain out (a normal occurrence when drilling holes in glass panes), and that's why the manual calls, in such cases, to run the discs through hard material for a while to "resharpen it". Kinda counter-intuitive, but when you know "how it works" it makes sense. (In case of glass grinding core drills, the drill is pushed into a block of aluminium oxide, aka corundum, normally used as mild abrasive stone for hard steels, like HSS.)
@@MrKotBonifacy wow what a great explanation thank you. I have seen WC inserts being made and knew they had a binder hence my question about this "diamond powder", much appreciated
@@campbellmorrison8540 Be my guest : )
Also, I just noticed I omitted one sentence in my previous comment - nothing critical, I just forgot to add "and when the material of matrix/ binder is heated (during sintering) individual pieces of it "glue" themselves with their neighbours, akin to what happens during so-called forge welding".
BTW, that "self-sharpening mechanism" works for all grinding materials - ceramic discs for bench/ die grinders and angle grinder ones as well.
And, oh, "there's one more thing" ;-) I answered few other questions "like yours" here (there were more than few people asking the "about the same" but the author never answered these so I chimed in, but kinda lost track of what to whom I typed), so anyway:
_"What sort of grinding wheel do you use for grinding diamonds?"_
Fro "grinding diamonds as such" a paste of diamond powder and oil (vegetable one?) is used - this is how they make gemstones of rough diamonds, but in this case here you don't really "grind diamonds" but the matrix material and a little bit of the outer part of that steel discs - for which a regular silicon carbide (SiC) ceramic bonded grinding discs are used.
And they sorta-kinda manage to do just that, HOWEVER, whenever a diamond piece embedded in the matrix meets that SiC disc it just rips it apart, like a steel ripper rips soil - hence the insane amount of dust produced in the process (it's all SiC grit ripped off the grinding disc) and the rate these discs are used up in the process. But then you have to smooth and flatten the edges of these diamond discs, and SiC-ceramic discs are relatively cheap, so this is how they do it - and then there's no way around it anyway. Even if they tried to use a diamond abrasive wheels (i.e. discs with a thick layer of diamond grit embedded in brass or bronze, or in resin or rubber, which are used in machines for grinding and polishing glass pane edges and for fine-grinding of carbide tools, like tipped saws) these discs would probably get clogged with all that "non-diamond" material. Can't vouch for it, never saw it happening, but I've heard from someone running a carbide tool sharpening shop that whenever a carbide tipped circular saw requires "deep" grinding he uses regular corundum discs to remove some of the steel behind carbide tips because steel tends to clog diamond discs (in the same fashion like aluminium, which clogs regular cutting and grinding discs).
And then these diamond discs I just mentioned aren't exactly cheap either, so I guess that "SiC-ceramic discs" option still comes out as the cheapest one. But this is just my educated guess, so don't take it as any Holy Revelation of sort ;-)
So inefficient! It's stunningly inefficient. Like before automation was invented.
What about the worker’s?
All that manual labor to make a couple blades, they must sell for like $500 each?
what if they made a blade made
of all diamond.. that would
be so sharp!!!
Diamond is not sharp.
@@ShainAndrews not with that kind of attitude
Something I just realized is that the wear on those machines, like the lathes, grinding tools, anything with moving parts... has to be unreal.. with all that diamond dust settling on everything...
That "whole lotta dust" is actually MOSTLY (like 99.9% I'd say) silicon carbide (SiC) dust from all these grinding stones used to smooth/ flatten the diamond grit holding matrix. While the matrix is pretty soft (bronze or brass, I reckon - maybe aluminium bronze or silicon bronze) the diamond grit wreaks havoc on much softer silicone carbide, hence the insane amount of dust - but then again nearly all of it is evacuated before it can "float around" and settle on the machinery. But some of it probably does get airborne, dunno for sure.
I imagined, that Korea is a hi-tech country. It's weird to see, that there is no automation of manufacturing process.
after watching this video, I think the disks grinding or cuting are very cheap. therefor they must have more price then this fee in this bazar.

Just cut my finger with one of these. ( not same brand ) Only a tiny wound luckily. Funny thing it doesn't hut nearly as much as a cut from a blade.
I know this factory and their products, looks like they changed company name.
Look no Robots.
diamond?
:( no hearing protection for the press operator
So, what do they grind the diamond edge with?
Looks like regular silicon carbide (SiC) grinding "stone". And it isn't grinding "diamond" edge "as such" but mostly metal - i.e. steel discs and the brass (probably brass) matrix (that darker, thicker stuff around the circumference of these discs) which holds diamond grit, so "yes, we can". But still, the diamond grit "does its job too", and it grinds down much softer SiC disc like crazy, hence this insane amount of dust.
Anyone know what is mixed with the diamond powder that hardens and holds the diamond dust on the metal blade when they bake it?
The solders contained powders of technically pure metals in the following approximate ratio, %
(wt.): 20 Sn, 43 Cu, 25-30 Co, 7-12 W.
Synthetic
diamonds with a grain size of 315-400 microns are introduced into the mixture of metal powders. An aqueous solution is added to the solders as a binder a solution of polyvinyl
alcohol in an amount of 12% by weight of metal
powders. The samples with the applied diamond-containing mixture are dried and then annealed in vacuum or neutral gas at a temperature of 820 C with an exposure time of 40 minutes and more. p.s When you open production, invite me to work as a technology partner.
Seems like they use quite a bit of time and grinding supplies to dress the cutting edges. Why not sell them with the full amount of brazed diamonds? They save cost and I would get more diamonds to cut with. Does any brand sell them undressed?
I am wondering the exact same thing.
We hoped that AI will do repetative work instead of us to have more time to paint picture and do music, but something went wrong way...
Not clear: how small diamonds are attached to the disk ?
The diamond powder is mixed in with metal powder. That way they can braze it (weld it). Diamond by itself couldn't be welded i reckon.
Those are all jobs for Optimus Prime
Primitive, but they're getting it done.

7:47 I'm sorry, what process??💀
Méthodes complètements dépassées on se croirait en 1950......
Well I'm not complaining about the price anymore
why would there be a direction of rotation?
PROBABLY because of how ridges on cutting edge are shaped - they are meant to make cutting more efficient and (probably) make the disc last longer.
For those disks... I see no reason for them to be directional. Probably an artifact left over from other image files used on the laser that were modified for these disks.
