Electrical discharge machining (EDM) Demonstrator from Trash Parts

I wanted to try out EDM on a small scale before heading into my "EDM graphite die sinking" project.
So i took what i had on hand and build a little demonstrator.
Arduino code can be found here:

I have learned from Baxedm that you need to use water with a specific conductivity to generate a spark on close proximity, not on contact. Thought I’d share Awesome project!

[@palliyil]

I think using deionised water instead of oil might give you a clearer view

[@chrisfairbrother9197]

Deionised water is used on wire eroders that cut with brass wire. Spark eroders (edm) use a light low flash point oil. So, sunflower oil is is good starting point.

Using a solenoid to lift the electrode everytime of conact works perfectly and maintains the spark gap

GREAT !!! thanks for sharing...

[@claystorage]

yay this is great! break us into that edm !

IM Jaffery How are you? I hope you will be fine Your video is great to watch. I have understood the mechanical, But could not understand how motor forward and reverse is happening, if possible send circuit diagram Yours sincerely,

[@Ace2Tactic]

Can you show how to wire the arduino please

[@chrisfairbrother9197]

A very good start on a simple edm machine. Try cutting something hard like a ball bearing to prove you can put a shallow hole in something you cannot usually cut.

i am working on the video of part 3 now and it will include some cutting of diverse materials

[@klausbrinck2137]

2-Eurocent-coins are made of steel, platted with copper (if it were pure copper, like other currencies earlier, the copper would be much more worth than the worth of the 2-cent-coin itself ;-) If EDM can cut steel, hardened steel shouldn´t make a difference...

Awesome! Great work

[@boltzbrain3039]

Thx :) comments like this motivate me a lot

[@Mr.Smalleys]

AWESOME! I have everything I need here, I need to go back to your use of the H-Bridge but its just an arc to eat away from the metal or do I need something else, , off to watch more and learn, Thank you.

One could say you built a wire edm machine... Ba dum Tsss

[@hanifatuttaqiyyahnurf2609]

how long it takes? to produce a hole? or first stretch on the workpiece?

[@devilvortex1]

Not bad 30 min if is made from scratch only to see if is work.

[@richardmittmann1836]

maybe I wasn't paying attention, but what did you use as a powersource?

[@boltzbrain3039]

in this case my Lab Powersupply with 0-50V DC, i found that about 24v worked best for this case, on higher voltages the process was quicker but welding became a problem. And since my setup wasnt exactly stiff i tryed to avoid welding.

[@palliyil]

@@boltzbrain3039 What was the current draw? Will a 10A 24V SMPS supply suffice?

[@boltzbrain3039]

@@palliyil a 10A 24V will do the job

[@AllTheNamesWereInUse]

Was searching the comments for this also. Thanks :)

Hello Sir,would you mind sharing a schematic... I'm really not able to follow up from the video.

[@waypointproductions8248]

Hello BolzBrain .. Hey I was wanting to message you to give something a try ... I think you can cut your time cutting through a whole lot quicker.

[@KrishnaKumar-ro3pz]

You all seem to have the required kind of trash lying around. Unlucky me. But nice setup

[@klausbrinck2137]

Yeah, I even think I noticed a unicorn and the emerald sword in the corner of his workshop... ;-)

[@AhmedMohamed-yj3kt]

can you make a drill edm ?

[@boltzbrain3039]

i am planing to do a die sinking edm, if that works i may do a drill edm

[@rok1475]

Please don’t put any more thumping background music on your videos. Very few dance club enthusiasts are interested in EDM.
