I worked in WIZO EDM a long time ago, specializing in wire and sink EDM work. Watching an EMD process is like watching paint dry, but Trevor, you made EDM look exciting and fun!
Haha I agree Karlo, it’s a little different than watching Barry plow through a piece of steel 😆 but the technology is certainly exciting in its own way!Thanks for watching 👍🏻
I work at Micro 100, and I machine tungsten carbide boring bars on a daily basis. There are many things that you have to be careful of while grinding tungsten carbide, varying from the temperature of the room to the amount of carbide that builds up on the grind wheels.
I love seeing the versatility of wire EDM machines and how they cut through so many different materials effortlessly. Thanks for the info and explanation on tungsten carbide Trevor!
Uhmm, guys, tungsten carbide is a _ceramic_ (a compound consisting of a metal element and a non-metal element), it's not a metal (alloy). But given that C2 Tungsten carbide has 6% cobalt in it, it's actually metal ceramic composite material, often called a "cermet" (ceramic / metal composite). But you can't really call it metal. (Sorry, I'm a materials scientist & engineer / metallurgist, I can't *not* be pedantic in this case!)
My dad specialised in spark erosion in the 1960s -1990s using a Charmille EDM with a relaxation circuit. This was ideal for tungsten carbide sparking. His main work was machining cold heading dies for screw/nail manufacturing. The electrodes were made of tungsten copper.
It makes the sludge that's left behind extremely abrasive. Really useful for cleaning some things, but definitely not something you want to leave behind on the machines table surfaces.
Awesome video. Glad you touched on slug management by adding that rough cut;, arguably the most important topic for lights-out WEDM when cutting any metal.
You are right. The TC itself is a ceramic and in the commonly used form in machining tools, it's "gled" together with a metal binder, e.g. cobalt. This makes the complete material a metal-ceramic composite.
@@DeusEversor Steel is an alloy where the carbon content is not so high that the entire material is cementite. Tungsten carbide is a ceramic and if it were still bound together using tungsten, maybe it would be an alloy. This area I am not an expert in, but tungsten carbide itself is a ceramic. Cobalt or nickel are commonly used to hold the grains together
nah it's machining. It's just in another form like grinding.. that too is within the subject of machining, tho neither are chip cutting machining methods :)
@@therealsourc3 If you go into the nitty gritty details: No, EDM isn't machining. The metal removal is done by spark discharge, where the heat of a very localized electric current causes the material to melt locally, so that the liquid can remove the solidified droplets. In case of conventional machining and grinding, the removal is mechanical.
Pure tungsten carbide is a ceramic (a chemical formula with a metallic element and a non-metallic element). Commercial tungsten carbide typically has some metal added, to create a cermet, a ceramic metal composite.
@@reidb9422"shaping on a machjne" isn't called "machining" in all cases. It tends to be "shaping _by cutting_ on a machine" that is called machining. Forging is also shaping, but using a powered hammer to forge is not "machining", yet it is shaping on a machine too. A powered bead roller is a machine, but rolling a bead, while it is shaping, isn't machining either. A powered tube bender? Same argument. In terms of fabrication/manufacturing, "machining" is mostly used when referring to shaping by cutting chips off. When you use a big ol' CNC grinding wheel to shape, you don't speak of machining, but of, well, grinding. But, hey, let's enjoy being pedantic for a moment and move on. This is all just unwritten convention, it's not legislation or anything.
You can also cut some grades of ceramic turning and milling tips as well, if it conducts electricity it can be cut some materials cut better than others. They are an amazing machine ❤️.
Your work is very inspiring. Our main products on the wire EDM machine is cutters with PCD or CBN cutlayer on tungsten plate. We also produce base plates for cutters, tool blocks and tool holders for metallmachining.
As a GOLD OBESESSED and working alot with Tungstencarbide endgauges . I love the GOLD LIKE WEIGHT of that awesome super metal called TUNGSTEN☆☆☆☆☆ Grtzz from the Netherlands johny Geerts
Use a Norton form diamond wheel, with flood coolant in a surface grinder. And you can put them in with a better edge. The EDM leaves a slight Hone. Not every customer likes a wire EDM cutting edge. A ground edge side wheeling on a grinder will always give you the best cutting edge.
For the features you are cutting I would agree the EDM is the way to go no doubt. I have to make 700 series tungsten ballasts for the military. It is all mill work. What I have found to work the best and last for a little while are the HARVI III endmills and the HARVI 1TE for the smaller range endmills. The GO drills do and excellent job and I use an OSG tap that is for inconel. I just approached it like running titanium and adjusted from there.
@@magicponyrides Yes it would be silly to essentially cut an endmill with and endmill. This is why I said I cut the 700 series tungsten. I mentioned it because most websites say the same thing , do not even try cutting in a mill, lathe possibly, but to use and EDM, Sinker, or Grinder. With the features I have to machine and the time frame I am given an EDM or Sinker just aren’t going to cut it and a grinder isn’t going to make the features.
I notice that this edm machine cuts and removes the copper after it was used to burn the piece being machined. Is this because the copper cannot hold a charge more than once? If we take an analogy of a saw blade, is it acting like every tooth of that saw blade is being ground away immediately after 1 use?
Is it cutting up the used wire into little bits? If so, that is super convenient. Last time I saw an EDM it had a bin with a giant tumble weed of wire which was densely packs at all.
Great video! Question from my side: could you show how that wire can cut a conical hole into a block and another one: do you have a 4th axis attachment for that wire EDM to demonstrate chip and pressure less "turning" of a tiny part ?
From my base knowledge, it'd have to be a shallow angle cone. The one I have access to I believe is like less than 10 degrees, maybe 12? Basically you offset the.. I'll call them guides and make a circle. Angles increase the chance of wire breakage which isn't fun.
Tungsten Carbide isn’t a metal - it’s a ceramic and not even the hardest ceramic (that’s boron nitride (although there is a argument between that and boron carbide)). Diamond is just slightly harder than Boron nitride and carbide. The material here is however cobalt / tungsten carbide reinforced composite.
Whatsup all at Titans of CNC, first off I absolutely love everything you guys do, it's really inspiring to all of us in the manufacturing industry... Trevor I'd love to see Barry machine this part on the mill and show you the chips 😂. As one who is an all rounder and works on milling machines, wire edm machines, cnc lathes and edm sinkers, grinding you name it. I have one question..... Trevor when are you going to drop us a video of 6axis wire edm machining? Keep it up all the way form South Africa.
On my charmilles 510, E2 rough cut is 0.25 wire plus spark gap is total 0.36mm, E6 would remove on a pass cutting steel 0.030mm E7 0.040mm E10 0.007mm E11 0.003mm. The thing to get your head around is an edm works on mm/min and lasers or mills or lathes work on m/min so an edm is the tortoise.
It would be cool to use some chemicals to clear out the part without doing it by your hand and also don't loosing dimensions after proces such. We use WEDM in our workshop for 6 years now and i didn't found right anwser yet. Maybe because i wasn't serching for it to hard ;)
I've tried to cut tungsten carbide once with angle grinder. It didn't work, the part just broke in half beacuse of cutting wheel wibration, but cutting it normally would be almost impossible.
Amazing work as always. Would love to see references to what services you use for your video production in the description as well. I'd like to know who the artist is for the song at the end of the video
Is Imperial Ra different to Metric Ra, if so, how would you „translate“ that into Metric (the usual 25.4 ?) Asking because we grind carbide (mostly for tooling (drills, end mills, reamers…)) and we aim for Ra 0.15 or better (usually around Ra 0.03-0.1)
I need this metal to make nozzel thorth on rocket engine. Direct contact with combustion chamber and behinde cupper heat pipe or graphene to radiate the heat from the thungsten carbide.
Great video! Always enjoy watching your videos and love the education you provide. Sorry to say that but Carbide is not metal, it's COMPOSITE. Nevertheless, thank you for the great work.

Cemented tungsten carbide is not a metal but a composite. Like you said in the video, it's tungsten carbide powder glued together with cobalt.
Correct 👍✋ I pointed out the same thing cause its very far from elemental tungsten

Just amazing how brass wire charged with electricity can cut right through tungsten-carbide
Very interesting the way the cobalt binder erodes before the carbide. Cool info man!

I started my apprenticeship on a makino u6 &u3 less than a month ago, I love every minute. Watching wire burn never gets old!!!!!
Tungsten carbide is not a metal, that is commonly mistaken. Cool machining nonetheless!
would you call it a steel then?
And iron carbide (steel) ?
