- This video introduces the novice machinist to electrical discharge machining often referred to as EDM. Electrical discharge machining is not generally used by novice machinists but learning the basics of the process can help to impress a future employer or bring someone to farm out certain operations to a specialized shop because they would understand that this technique could help in completing and important part.

I hope you are using some sort of breathing protection when you are cutting the carbon electrodes.
Hi Terry, You are very right to mention that. Yes I do use protection and I should have mentioned it in the video. I will pin your comment to the start of the comments section so others can benefit. Thanks for writing and for taking the time to write. Marc
Thanks for the comment, Marc. Nice video and explanation of EDM machining. Before viewing it I knew nothing about EDM accept for its three initials 😁; now I'm much better informed. It's seems sorta like focused ultra-sonic cleaning that is ramped up on steroids!
THANK YOU!!
I just heard about EDM realizing it's not just electronic dance music🤩
Yours was far and away the best video on it I found after searching for an hour. Absolutely fascinating process and your video was spot on. Clear, concise, to the point, and covered enough that I think I have enough to go on to speak knowledgly about it.
I have seen easily 40 small shops auctioned off every week for almost a year now.
I was going to start a surplus business, but I realized I don't want to be a part of helping people lose jobs and businesses they have run for 30 years.
I LOVE Everything about metalworking, but have never touched more than a hacksaw. I built 2 very successful businesses in industries I had no interest in, retired by 37, but lost everything in the recession. I have a crazy idea to create a business that I think can help these small guys who never upgraded, and just want to retire, but won't get anything if they auction or try to sell with a broker who will take 12% cash up front out of the deal. EDM could be one part that I missed.
Thank you again for the video, and I love your website. It's going to be an incredible resource for me.
When you come down here to south Florida for the winter, I would love to meet you.
My Dad was born on Windsor, and we have a cabin near North Bay, Ontario.
Thanks again,

@@THATLAZYMACHINIST was that carbon of graphite made electrode ??
@@joediverfl lol that’s too funny! I started working with EDM over a year ago, and I still think of electric dance music! Some the older guys at work just don’t get it.
You did a great job -- EDM is an area not widely covered on machining channels .
Home Machinist should appreciate your video.
I do. :D
I am a dentist, and some of our endodontic files are EDM. That's why I´m here, and even my self understand this process. Thank you very much sir!
Great video, Marc. Thanks for taking the time to make it and share it with your viewers.
Many years ago I was able to work at a machine shop and they had a wire EDM. I never got to see it run but the machining abilities were amazing at the time when I saw some of the examples it produced. I appreciate seeing the mechanics behind that as you presented them.
I like your style of teaching, speaking slowly and clearly, and giving the accurate pieces of information. Thumps up!
Thanks Marc, my first introduction to EDM. Heard of It, but never saw the details. Thanks
You are providing great pedagogy and also high quality illustration. Thank you very much for the time and efforts you have dedicated this great teaching! I enjoyed it very much :-)
Very thorough explanation. No questions, here! Thanks a bunch!
I just love it when machines go all the way up to 11... that means it made by people who mean business, and who have a sense of humor.
As an experienced machinist I still enjoy your videos and sometimes still learn something new or different, keep it up
YES!!! I was just going to comment on that! Nice observation.
I thought I was the only one who noticed that. Power going to 11 someone definitely had a sense of humor
Back in the groove! Excellent video, sir.
Nice to see the basics of EDM being shown.
This is one of the best channels on CZcams. Nicely done.
Great video, very informative! Keep'em coming! Thanks for the work that goes into making these videos.
VERY interesting video Mark!!!!! Thanks for taking the time to produce and upload.
Cheers from John, Australia.
joandar1 hi sir
I am a tool manufacturer in India. I want to sell my products in Australia or all the world. Can u help me
Merci pour cette super vidéo, l'électro érosion est trop sous-représentée.
Bravo, depuis la France ! :-)
Thanks for the clear and simple explanation. I only recently learned that EDM even existed. This has helped to gain a basic and useful understanding of it.
Watched a video of a large broken tap being removed with an EDM. Thank you for the clear and concise explanation of this process.
That is some good background wisdom you got there. High precision, high accuracy stuff
Nice one Marc, enjoyed.
Great Video, hope to see more!
Very cool. Thank you for sharing how this is done.
Dear Marc, thank you for your next superb vid!
In the next video, I will probably produce a double lobed crankshaft for a small steam engine. Why? Why not, it sounds like fun and that it what it is all about. Thanks for watching and for taking the time to write, Marc
A really good all round intro to EDM - thanks for sharing the video. And I love that the machine has power settings up to 11. Nice to see a sense of humour in tool designers!
yeah, but he wasn't game to put it on 11 and live life on the edge.
Reminded me of a scene in "This is Spinal Tap". LOL
Thank you!
I appreciate you sharing your knowledge.
20:44 Current goes up to 11. Nice👌🏼
That was such a good into to EDM! Well done
That is really an amazing process. Thankyou.
That was great. Thanks Marc
Very well done!
Fascinating, well done, very well articulated. Thanks!
Thanks Josh! It's all for fun and I am happy to know that the video is appreciated. Marc
Thank you! Love your videos
Thank you very much for such a nice video, very detailed and pedagogic, all the best!.
Awesome lesson. Thank you.
Great video! I'm subbing. I came across this vid because I wanted to understand this process a bit better and your vid is great!
Thanks for posting this informative video.
Thank you, very informative.
It's really helpful for my study. Thank you so much!
VERY GOOD SIR....THANKS FOR SHARING YOUR EXPERTISE ....MAY GOD BLESS YOU
Sir you are a master ,I was looking for info in this field and you gave me it all thank you
Your tools are very cool! Thanks.
Thank you, so interesting..
Bundle of thanks sir.....
Love and respect from Pakistan
That’s amazing. Thanks for sharing.
thank you for the highly educational video.
well done never new such wonder of a thing all the best from John in Texas
You have a nice style. Thanks.
Amazing stuff , Thanks .
Thank You for this, I learned today!
Very well explained. Thx.
Great video!!!
Thanks - I operate 2 die sinker EDM and a wire EDM and I watched this from end to end and thoroughly enjoyed your presentation :)
What kind of parts do you make? (Just curious. I'm going to make an edm.)
Great explanation, thank you.
As always, I am SO thankful for your videos and taking this time. I hate to have to point it out, but at about 7:20 when your words are on the screen, you have the word "SAYIMG" vs. "SAYING". Please keep up the fantastic efforts you make for us all!
Very informative, thank you!
Love the video buddy! Very informative, helped me out a lot:)
Wow.I finally know now how EDM works.Heard about it,knew it existed but had no idea how it works.Thank you.

Hey, you're back! ;-)
Hey Marc,
Happy New Year to you and all of your viewers! Here's hoping that everyone has a safe and enjoyable 2020!!! All the best, Terry!!!👽😎🤠
Your videos are always great ! Thanks for sharing, and thanks to "Patrick" too for her support !
EDM Machine used more than Die for injection moulds purposes I have 12 years of experience in this machine in India Hyderabad
Thanks , Enjoyed. Like the humor, later from Texas.
Nice to see a good serious runthrough with an older style EDM and older 3R style holder. I started on EDM on modern Swiss Agie Charmilles machines that generate their own settings with touchscreen interface- wondered how the older ones I had seen before worked. I heard the oldest had mechanical orbiter mechanisms...cant even imagine what it was like to run those
Brother, if you want to see one, you can check my latest upload... I just saved one that is nearly new-old stock grade from being tossed to scrappers for pennies a pound... You wont see me use her for quite a while, as i have to build a new shop to actually house all the machinery that i hoarded in anticipation of a proper shop, thereby crowding what was my current shop to point where I have 11 machines waiting a maintenance or a large service or even a full restoration... I know that i`m 4 years late to the party, but 4 years ago i had just a few machines and never intended on having and EDM machine... 2 days ago, i was tossed one into my lap essentially, and i`m referring precisely to the Granddaddy Charmilles D1T orbital sinker, which i intend on running both as an EDM sinker but also as a Jig grinder, as all the dust can easily be contained with a separate oil tank that will keep all the dust inert and harmless to any machine, thus not harming the machine in any way... She has 2 micron dials and a 1 micron DRO, so it would be ridiculous to fail to utilize the full potential of a machine capable of containing grit like no grinder or dust vacuum ever could... In the end, whether its ultra hard mould steel particles that EDM generates or abrasive dust from grinding, both are extremely abrasive and are nearly identical in regards to being harmful to machines if not perfectly contained... Even the Moore Jig grinders can`t boast about that ability... Neither can Hauser ones... The machines you are referring to are literally out of this world in regards to their quality... It`s little wonder that Charmilles still exists today, even tho in a marriage with Agie...
I know this is kind of a shameless plugging of my own video, but really, it`s not, this is a 5yo video and a 4yo comment, so who else could see this reply if you don`t check it out... It`s a personal communication as i would like to hear more from you if you know anything about the D1T... I`ve got all the books, but they seem to be unicorn grade machines... And i want you to see one if you never have seen them... They really are works of art...
All the best and kindest regards!

Keep teaching. Our society needs these skills and those that perform them.
And yet that society only wants to pay them 12 dollars an hour, and we wonder why the country is failing.
@@abdullahwisimulacha4770 yeah, no. Western society was founded upon false hope. They were in control long before America
Good information and vid. slowly getting there my self and hope to be as informed as you.
Great video
Not much info on EDM machining on CZcams.
Showing us milling graphite electrodes was a nice touch.

Very cool, thanks for the video
Excellent!
Possibly the best explanation on youtube!
Thanks for the compliment, thanks for watching and for taking the time to write. It is appreciated, Marc
Great video, years ago I broke a head stud in an aluminum snowmobile engine.
A friend of mine worked at Boeing and used EDM to remove the broken part for me.
I had wondered how it was done.
Thank you for sharing your video with us.
Thank you Marc. That was very educational. I imagine someone having an EDM in their home shop would make them a very happy camper.
Great video, very informative, good explanation and very good film quality. thanks for sharing with us. Dan
Film was not used.
thanks, man, it is very interesting, nicely explained
Great video 👍🏻👍🏻
Have anyone said when machining graphite use a shop vac to suck up the airborne graphite dust.
when we machine graphite electrodes, that is what our machinist do to keep from breathing the dust.
I operate commercial edm machines. you have done a very good job in showing EDM.
This was very good. It shows an alternative method of machining through hardened steel and any other materials that conduct electricity. Zero warpage, no loss of material tempering, no heat damage of any type was done with this process... Nice!!!
Well, a disadvantage of edm is that just near where the sparks were, there is a heat affected zone which changes material properties a bit :(
, @Robbie James, That might be true with the metals that have low critical temp. / heat affected zones, like aluminum (475° F) . But the female thread can still be repaired in several cases, with a thread repair insert, and the EDM could remove the broken pieces , without significant collateral damage, that is often associated with schlock techniques... So EDM is STILL necessary to do ANY kind of repairs to the threaded castings made of most types of metal that conduct electricity, and then saving the castings from being scrapped... Therefore , EDM STILL has the distinct advantage of removing stuck - tooling/fasteners the best way known, to get the machines working again, at MINIMAL expense... BTW, because the EDM process uses liquids like soluble oil and water mix to help disintegrate the stuck pieces, the water also COOLS the surrounding metals from becoming affected by high heat, and thus localizing the intense heat to the parts being disintegrated... EDM is DEFINITELY the best way to remove stuck fasteners and tooling from hard to find / expensive pieces...
Tres good I enjoyed
great video Marc....never seen this process before
Yet you are "teaching" people machining or whatever your videos are about...
This is not something we see in the machining videos. Now you've got my interest up. I think this would be a great addition to a shop. Good luck doing that D with a cnc, let alone in hss. I love your quotes.
There are things not covered in the Internet. EDM is one, next one (same field, injection molding) is proper polishing and "texturing" surfaces, plus repair welding (single pulse micro-TIG and laser welding). Top Secret (almost) stuff.

Very interesting video ! Thanks Marc. also, it's good to know that EDM is not a type of cheese.
I regularly machine graphite for glass working. A shop vac with a drywall dust filter and nitrile gloves help keep my lungs & hands clean.
Hi Marc - TYVM. EDM is usually used to produce tooling for near net shape sintered PM parts, as you know. But while watching your excellent vid for some reason I kept thinking of the novel "1632" by Eric Flint.
Thank you Marc, and those who helped you in producing this video! I have heard about EDM before but, this is the first time I have seen it performed. I am glad that I got to see it through your perspective. Now who is going to help you get all that graphite cleaned up from your shop? You will be finding hidden traces of it for months! I used to do a lot of Cadmium plating using those electrodes. They are messy when being shaped!
Hi Scott! I would like to thank everyone that is involved but this is a one man show. There is a reason why my videos look amateurish, this is my little retirement project that I do it mostly to help others and also because I find it fun to produce the videos. And yes, I am alone for cleanup as well! Thanks for watching and for taking the time to write, Marc.
Hi Marc, I was referring to your statement at 28:39. I am a long time subscriber to your wonderful channel. It is obvious to me that the turning and mill work was done in your shop. However the EDM portion was not. Hence, my reference to "those who helped". Once again I want to thank you for ALL the effort that you put into sharing your knowledge with us. BTW, I don't see amateurish, I see a teacher having fun!
Great video, Marc. I didn't know very many of the aspects of IDM, until your video. Thanks for sharing!
But you're "entitled" to "teach" people machining, or whatever your vids are...
How timely I just bought a book about edm and waiting for it to come from America. I fancy building a tap burner. Although wire EDM eroders do some amazing work. Does the machine use pulsed DC when cutting, or is the frying noise just a function of the arc lengths.
This was rather interesting.
Thank you!
thanks much very helpful .learn something.
Triangular toolpost is brilliant.
Thank you.
a good tuto work thanks
I was a moldmaker. 5 axis EDM was a very important process. A very versatile process. A very good process for porting gun barrels due to minimal bur. Set up a tungsten electrode and fixture.$$$ I've left the industry but, it was profitable while I was a moldmaker....
Very cool! What type of dielectric fluid did you use?
Thanks for the video. I remember in the 80's EDM was gonna change the world. I imagine today getting rid of an EDM machine is like trying to give away a free CRT TV.
Hi! If there are free EDM machines that need new home please contact me.
Not if you are in a precision industry. Turbo molecular pump impellers are made with EDM.
Hope you make more vidz on this and how to do hard to make parts
That was great.
D first electrode was good but the second electrode was very groovy man! Thanks😉
Divad Ignawm - what a strange person you are...
I mean the first electrode was D shaped so there was a deeper message which you weren't able to unravel until you encountered a witch like me. 'Cmon boy go show her some romance. whip her with it. Whak! Whak! she will laugh like you've never heard. hahahaha.
Well I sure learned a lot!
I see when you need that extra push over the cliff, your EDM go's up to eleven
Thanks for the wonderful video demonstrating EDM. I was wondering how the power consumption of EDM compares to the power consumed by a commercial lathe or something like a Bridgeport mill?
Thanks and it is good to see you making videos.
Great vid Marc! An educating one for me... heard of EDM but have never seen it until now! Thanks!

Ditto
Also known as "spark erosion", well here in the UK anyway. Very interesting video young man!
A really great video, i learned a lot, but a comment on the hazards of graphite dust might be appropriate. In industry a lot of precautions are taken, i think. Great work, none the less.
