- Welcome to the first episode of the Everything EDM - Learn to Burn series. Zero Tolerance LLC zeroes in on electrical discharge machining (EDM), starting from the basic concepts.
There are many different names for this subtractive manufacturing process: spark machining, spark eroding, die sinking... the list goes on and electrical discharge machining is considered a "non traditional" or "non conventional" machining process. This video, Introduction to Electrical Discharge Machining, will show you how, what, and why.
00:15 Introduction to Zero Tolerance and how they use electrical discharge machining to create their plastic injection molds.
2:14 Beginning the electrical discharge machining process of an intricate mold.
3:37 Using the electrode holder and how it works.
8:43 Continuing the electrical discharge machining process of an intricate mold.
11:24 Quick lesson about how the electrode and voltage create the spark and cut the metal.
13:31 No broken cutters with hardened steel and EDM.
14:01 Thank you and closing

Just wanted to comment on the gracious footnote that Steve provides at 14:05 where he states "......so [if] somebody has taught you something in the past, ... I always recommend that you thank them, and continue growing to honor their input into your life".
Given all the degenerate crap in the news, Steve's gesture was a humbling gift that made my day......thanks.
Charles, happy to hear that! thank you for watching
Thanks for watching!!
The best way to honor you mentors is to pass in what you have learned.
I am a tool and diemaker of 40 years and I just really enjoyed your video, and your explanation of the over burn. I was trained in an old edm that yes we used super glue, on the carbon graphite and small c clamps and all kind of stuff, ah the good old days..😃
I'm more of a fan of electrochemical milling: essentially reverse electroplating.
Selective masking confines metal removal for etching graphics; a formed cathode can 'plunge-cut', leaving a hole with the same profile as the tool.
Wire EDM is more precise, but tool configuration prevents making concavities on flat surfaces.
ECM with a shaped cathode works very well for plunge-cuts and concave surfaces, but requires 100's of amps, high-pressure electrolyte pumps, cooling and rigid fixtures...
EDM can plunge-cut, but the tool is consumed.
I've used ECM and masking to make decorative designs (back-filling etched areas with silver-solder), roughing out the shape of knives (think terraced hill-sides) from steel billets.
Fascinating process.
Great video Steve! This is an amazing resource that you're creating for future EDM machinists. This sector of manufacturing definitely needs more light shed on it so I'm sure that many people within and outside of the industry will find your knowledge useful.
Thank you! We are excited to continue this EDM series and help others learn more about EDM technology. Thanks for watching
Very usefull 👍waiting for 2nd session of edm keep it going🙌
Sure I know what EDM is *untz untz untz*🎶🎵😂
How cool is that water bed coming up ...👏
Fascinating content since most don't see much EDM. Really want to see more of this kind of content, so thank you. ZT has some impressive machinery and EDM is magic for tool & die workloads.
An inexpensive lapel mic will greatly improve the audio. Looking forward to the current and voltage info as well as the lifetime of the graphite electrodes.
Thanks James!
Imagine how strong u could make parts out with this method there's no real heat except the area its decomposing ...
U could make perfect pulleys . crankshafts.
U can run this at any axis...
Great information! Thank you!
That is cool, I too run a Neuar and a Sodick Edm, just great to keep learning. Been doing it for four years.
Always new things to learn! Thanks for watching
Have always found the process interesting, always wanted to learn more about the sinker process. Worked in a mold shop for only 4 months, and only saw them run the sinkers they had twice the entire time I was there. But they have wire EDM and hole popper EDM where I'm at now.
Wire EDM seems to be more popular in some shops, depending upon the work that comes in. In our latest episode we explain why sometimes it makes sense to burn more of the job than to mill it, in our shop anyway. Our sinkers & wire are always running. It really helps keep the work flowing utilizing another path of getting high end results.
Thank you for this video !!
Thanks for sharing!
Thank you. This is a very clear explanation of how the process works. I did my tool makers apprenticeship at Ronson products in the UK in the 1960,s There was a spark eroder machine that was frequently used to rescue a workpiece that had a broken tap in it. We utilized it a lot 😂
That's awesome, thanks for watching!
Really? I’m still wondering what it’s all about. 7 minutes before we even learnt what EDM means, ending with a machine hopping up and down. No explanation in here. He even suggests looking at RUclips for an explanation!
@@SirHackaL0t. well, I guess it depends on how a viewer understands the content.
@@ussweeneyd Maybe, but it’s title says it’s for those who don’t know what it is and are looking for some info.
awesome!!
Awesome videos. I run a couple a sodicks at my shop. Diffently alot to know on edm. Very fun job but can be stressfull, when you have a couple hundred electrodes to run for a job.
Thanks for watching!
I learned to burn on a manual Eastco Sparkatron in 89 then moved up to C axis Charmilles Roboform die sinkers. Big fan of Errowa tooling. Channel to launch Summer 2022.
That's awesome, thanks for watching!
I learned this before and this video is helpful❤
I subscribed you before two minutes in your video
Thank you!
The machine shop I worked in didn't make mistakes. Never saw one ever.
Nope, we had "happy little accidents", puzzles, and entertainment. Sometimes that last one meant we were getting a new guy soon.
This is the cool!
Thanks for the vid.
What is the lifetime of such electrodes? Can I do mass production of small parts using these electrodes? How often should I replace them?
Thanks.
Pretty cool, subtractative spot welder type machine on a CNC machine is a simpler way of explaining it, where the welder doesn't touch the project so it cuts away not adds to.
🙂👌❗
Thanks for watching!!!
I want this machine....
Excellent video! I've been interested in EDM for a long time but could never find any places to learn to run them or OJT jobs.
Stay tuned for more episodes! Thanks for watching
If you happen to live in Louisiana we're hiring! On the job training
Great video! I have a question: after edm cut, surface of cut section roughness is low, maybe after cutting, you will do polish process for it?
It depends on what the finish the customer is requiring or what the individual part requirements are. Thanks for watching!
Nice to see a modern edm in action. Where do you get the dielectric oil to buy?
We get some from Belmont and the Eagle came with some good oil that we like.
great video! Question: EDM process makes as good a part as the electrode. So how are the electrodes for EDM made? Considering there are limitations in other machining processes. Thanks!
Can you share who is the manufacture of the chuck that hold the SS block
Did you consider calling the company In Tolerance? 😏
We did not, but do like the idea!
Where can I learn how to run this kind of setup? How do I get started. I’m brand new and want to learn everything about this. Also what different kinds of edm machines are there. I have no clue lol. Thanks!
So if i wanna sink a square hole 20mm by 20mm do i have to mill the electrode smaller then 20mm or 20mm sharp?
Thank you sir
But i want to ask something at 14:35 you show us some products how can i measure the quality of this products ..am i use the plastic product or what ?
In general how to measure the quality of tinny products that come from die sinker?
In this work peice needed to dailing??
time 9:29. What kind of drive does pinoli have?
Awesome, unnecessary to dial of elec, and workpiece, how to touching and what parameter condition did you used if mirror finishing.?
Anyone knows how much they cost? Used one? New? For smaller work? Is there anyone around 4000 euro approx or what are the prices and quality of the cheaper once?
why not 3d additive print electrodes? at this point in time, that's gotta be a thing...
How the cutters are made??
Your machine is also CNC machine . What you are referring to as "classical CNC" is actually CNC mills and lathes.
can one buy the jig that dose the burning from your shop or how or where would you get one made in order to do your own edm burn
We buy majority of our tooling from www.sunspotedm.com
steve is it posable to edm a rmr cut on a gun slide
We manufacture and design alot of gun & gun magazine molds here, we use EDM and Wire EDM on every tool
edm does not mean electronicly displacing metal xD its electric discharge machining (i think)
Both terms are correct! We hear it referred to both frequently
“Electrically Displacing Metal”?
Or “electrical discharge machining”?
It could go either way, alot of folks say both.
Cool tech but this can be used for weapons coz' sand will clock the mechanism but it's so cool.
God bless.
Why put one these on a 3d printer and do the reverse instead of starting from the bottom start at the top removing material.
I got it a bit but what machine made the electrode so precise?
Afaik they have a cnc mill just for making the electrodes
does the electrode made on wire edm?
We machine our electrodes in our Makino F3 mill
Being one of those old timers I'll mention your not quite correct on the square corners knowledge. In your lifetime cnc Mills and lathes do the heavy lifting. It's easier to design around the processes available on the shop floor so square corners are avoided when possible.
A shaper can cut square corners and brooches can also cut square corners but usually requires a hole or pocket space for the chip to roll into during the cutting. Not many shops have shapers these days and the skills to run them is even rarer than the machines.
A waterjet can also cut square holes. The real advantage to EDM is accuracy. You can maintain far better tolerances than most waterjet machines and you can work in blind holes. A plastic injection piece to hold wires probably doesn't need tight tolerances. The die for this part could have been a dozen different ways using conventional machines and easier to machine tool steels and then had the individual pieces heat treated for the desired hardness.
If you got a guy with a burn table in the area that also designs and cuts his own electrodes for the task at hand and at an affordable rate then it makes sense to farm that part of the die build out.
With the internet and modern software, and a fast and efficient postal system, farming out work has become the new standard.
I've made square holes with broaches manually. This guy is full of shit.
or just a hot tungsten tool cutter, as heated up
🤔, this says nothing about 'erectile disfunction medication'...?
If you have an EDM that does accurate machining then why not make your own holders?
awesome technology. we also show videos of this technology on our channel. it's a fantastic technology.
"perfect" square corners, sure
LOL
What is the type of sensor that prevents the workpiece and the electrode from shorting each other. How is the distance measured by the sensor. Shunt resistor?
you call that an introduction?, great explaining power...
wait a minute…… this has nothing to do with electronic dance music!!!
Cant believe you Just used your hand to clean the surfaces...
J
I thought this was going to explain what EDM does to create shapes
... not an advertisement for what you can do.
Uhuh?

You never explained what edm is. I came for an introduction.
Could have better flushing on that first burn. Also we did make a similar clip with that christmas tree type clip. We originally made the die in insert layers, then we developed the first ever rotary electrode system, so we could rotate the electrode through the die insert.
