As far as I can see it there is no wire. He is using a solid electrode like in edm drilling

pretty sure its the electrolyte doing the "cutting"

@@ale6242 the electrolyte isn't doing the cutting but shielding/connecting the electrical circuit and pushing out the metal ions from each discharge event. it is just like water jet cutting but instead of cutting grit in the water, you are passing a current through the electrolyte to cut.

the flaired edge is because the liquid is doing the cutting. the rod in the centre just provide the liquid with a charge.

@@markcastonguay7906 do you always contradict yourself in the same comment?

That's very kind of you. Thanks so much.

how the fuck can this grab a hold of you? he's obviously planning to make a EXTREMELY overpriced piece of shit just like he guy he is trash talking in his video

The only thing interesting about this comment, is your profile which was made Dec 17/2021. Like 9 days ago :)

@@darkracer1252 An* "extremely overpriced piece of shit". Not so obvious if I didn't derive that from the provided information. You are entitled to your own opinion that would have been better off kept to yourself in this case.

@@Alex-si1bi you can watch videos without an account you know?

@@Nepoxification You can watch videos without _KZfaq,_ even (using Invidious)

Thanks, Taps! Yes, it's definitely in the plans to get that kerf smaller. Many avenues to approach there, so I'm not going to be short on work to do! Even if I could get the kerf to .5 or .25 times the current diameter I'd be pretty happy. That'd make it cut 2-4 times as fast as it is now.

@@ZURAD Hooray! Looking forward to seeing those experiments. Didn't realize it would also speed up the cut, but makes sense in retrospect. Will be interesting to see how much the thinner wire starts to deflect or not. Exciting!

Breaking Taps 😂 Good Channel name 👍

@@ZURAD try using spinning helical enameled wire (that's the thinnest conductive material i know ) and a slow warm stream of electrolyte cause its doing the heavy lifting....

It would be awesome to see your version.

Please do! We've got a more cleaned up and effective beta in the pipeline.

@@ZURAD I want to do thing like that but from my scrap laser cnc , could you tell what voltage you used and what was the current , it was pulsed or straight dc ?

Thank you! I think so too. This is really important work to keep improving on.

Thanks, BAX. Means a lot coming from someone like you. There's a TON of work to be done still.

Thanks so much!

Will do! We may have a kit at some point in the future to help with the decision paralysis

It's cool, huh? Thanks!

Awesome! Thank you! Still needs a lot of work, but it's exciting I agree.

Thanks 👍

Thanks! I will!

Stick around. We've got a lot of improvements in the works.

This is a really good point and something I've been concerned about. I have been successful with capturing CR6 in citric acid. The acid actually helps machining and lets the waste enter solution instead of floccing out. TBH I am going to be trying some EDM instead. Seems safer from a chemical perspective.

@@ZURAD if your Cr6 content is low enough (no more than 6 or 7% i think) then the iron content should reduce it without need for additives. If you need to run higher Cr material, your addition of citric or similar mild acid does help with safety, as well as dissolving the waste, such that flushing the surface is easier. It makes filtration a bit more difficult though, and the citric becomes an expensive consumable even at scale. Adding iron or sulfate salts will be cheaper, although they can mess up the process fluid quickly. EDM is safer and easier to control, but once you work through the challenges of ECM you have a very powerful surface forming tool, especially as the materials and shapes begin to challenge the limits of EDM. The two are often complementary. For example, your demonstration machine can deburr sharp edges and polish surfaces of a part after an EDM, saw or waterjet has made some accurate features with straight, non-tapered cuts. if ECM just does the last operation, there won't be as much waste to worry about.

@@TimothyNoronha I agree that EDM will be much safer and easier to control. If you check some of my recent community posts I've been having great success with EDM. We're even running a Kickstarter on it soon! You can sign up to the mailing list at rackrobo.io if you're interested.

Thanks! Will do!

Awesome, thank you! There's no need to run wire as in ECM there should be no tool wear.

Appreciate it

Very cool! Have you seen the E3D ASMBL? Looks awesome for finishing prints with machining

That's the dream!

AQTT - your comment seems to summarize best what others were attempting to describe as well. With that said, it seems to me that the solution to a controlled kerf width and less flare is to submerge the part, recirculate the electrolyte and move the swarf and current accordingly. But now were just describing basically an EDM machine with side cutting capability? This is a really cool idea - scaling down EDM technology to a desktop device.

Welcome aboard!

Thank you!

😆

Awesome. So glad to hear it! I'm available on the discord channel linked in the description.

Trying hard to keep it more signal than noise

Thanks, will do!

Thanks! Will do!

That is a very interesting idea. Afaik the taper is caused by surface tension against the work piece so maybe!

@@ZURAD the 2 ways i can think of reducing surface tension: 1. A wetting agent (like soap) in the liquid. 2. Increase temperature. A bit of soap in the water would be easy to try.

@@DuncanLaw Absolutely. I've been looking into different surfactants. I think it's pretty obvious why a low foaming one would be desirable. That's why I'll probably try something like dishwasher detergent

@@ZURAD Yup. Old fashioned powdered floor cleaning soaps might be worth a try too. They are highly concentrated and engineered to be non-slip for safety reasons which i presume implies they don't increase the viscosity of the water much.

For some cases you might make _use_ of the taper. As you know, a chamber for tapered cartridges without a lathe is the biggest stumbling block for DIY gunsmithing right now.

Absolutely. It's extremely simple for what it can do.

This is a thing commercially with ECM, but it's such a delicate to control process you're better off working on 2D tool paths or die plunging.

not really....this aint something you can simply change your tool for and start going.

More to come!

Hey, thanks!

🙏

Thanks, will do!

Thanks a lot!

Thanks!

@@ZURAD I can see this being very useful for a home shop.

Thank you!

Right now stuff works best with 1mm or smaller sheet metal, but we're working hard on making it better!

Pretty far! I'm hoping to do a new video soon. Started a company called Rack Robotics (we're on youtube!).

Thank you! Cheers!
