Dear friend
have u built this machine from plans/ books available only from three legends on this planet?

Pl. share your comments
sanjiv(group)

Hi Sanjiv, Did you get the plans of the EDM I emailed to you a week or two back? If not, let me have your email address againand I'll resend them.
Ian.

Would it be possible you could send those plans to me just to have a look at.

Thanks in advance

Bent

I would be interested in looking at those plans as well.. if not too much trouble could I be a recepient as well....

cheers
emmkay

Hi bent and emkay, I haven't managed to work out how to attach anything to this forum yet, otherwise I'd attach them. The best I can do is to get your email address and I'll send them to you direct.
If someone can give me a bit of a "show me" I'll be able to contribute on a broader spectrum.
"one picture is worth a thousand words".
When I hit the small box above to attach a picture I get a box pop up that says "please enter url of your image"
What's that in English?
Ian.

Ian.

Not sure where you are here, Ian, but if I want to send a pic, go to "Advanced".
You get the usual sort of type-in window, but with possibility of inserting icons etc., and lower down is "additional options".
Click on "manage attachments" - this opens a window where you can add several.
You just browse for the location of your picture in your own files.
When you find it, click on it to get the location into one of the small windows, then hit the "upload" button.
Then use the "preview" button to check all is well, then "submit".
If the pic is too big, you'll be told, so you have to make the original file smaller, then go through the process again.
Hope this helps.
John

Yeah, sounds interesting, I would like to have a squiz at that too !!!

The thought of blasting steel away with electricity sounds like a great way to spend a quiet Sunday :)

If you don't have any luck posting on the forum email it to me and I can have a go.

Russell.

Hi John, where do I find "advanced"?
Ian.

If you look beside the post quick reply button under where you type, you will see Go Advanced, click on that and it gives you more options, there will be a box with additional options under where you type, with a button named manage attachments, click on that and you will have another box popup that you will be able to browse and upload you pics...

Good Luck.

Russell.

dear ian
i searched a lot to my email box. i couldt found any trace of this plan. my email address is " jaimatakee@yahoo.com " pl send them, i will load the same on CNC Zone.

Hi Ian,
Russell's given you the final step, so I look forward to seeing the set up.
Sounds interesting enough to add the the ever increasing number of projects........ !
John

Here goes for better or worse...
Ian.

Hi all, I see you're all on line. Thanks a lot for all the advice. Now there's no stopping the monster, so be prepared to be bored to tears with all the "This is how I did it" or "Here's my latest creation/project"
Let me know if the plans are readable or otherwise.
I see the file sizes are only a few Kb's. I might try sending a bigger file next time and see how it turns out.
Ian.

Oops, page 6 is missing. I'll go back and edit it in.
Ian.

Ok. page 6 with the circuit diagram is up , so I hope it's what you want.
Ian.

be prepared to be bored to tears with all the "This is how I did it" or "Here's my latest creation/project"


Oh yeah, I for one think I will be one of those boring people to tears, now my router is finished (pretty much anyway) this sounds like a pretty sweet project, thanks for the inspiration.

dear sir!
what do u want to say by this?

THANKS IAN, i have this but i dont remember from where i got it as my computer was formatted due to TORZON HORSE. i will find PDF for same

Still no one has committed that he made edm by the plans availabe from these three legends

It appears that the design is using the E.D. Machining method for use as Tap-Disintegrator, commercial types of Tap-Disintegrators usually use simple low-voltage (3~6vac), high-current method.
This design should work for machining however.
Also the Robert Langois design is worth looking at as it uses a bit later logic control methods, and I am sure that there are many improvements out there on his design.
Al.

Hi Al, I'm presently committed to changing my stick welder to do tig welding, using the usual add ons of diodes for DC and an inductor along with a High Frequency gizmo.
Wouldn't it be awesome to add EDM to the average DIY stick welder. If the voltage was brought up to about 100volts the power would blow your mind...yeahhh!
Starting with the average 100 amp stick welder all it would take is a step up transformer to get the volts. Anybody got any ideas on this?
Somehow I don't think this is the way, as having downed the voltage and upped the amps for welding, it would take another transformer to achieve what a mains transformer would do straight off and simpler.
Ian.

I have built Henry Washburn's EDM from Strictly IC magazine. The setup uses a stepper and 48 volts 5 amps for the probe. Everything is adjustable including the timing for the stepper and probe. I use it for getting those pesky little broken taps and stainless parts out of alum. normally in the 4/40 size. I don't have the plans or schematic as when I was in touch with Henry they where copyrighted and would not violate his work.
The problem with mine is on the larger items where more power would help out. For fluid I use de-ionised water with a coffee filter for straining. Never have seen anything in the filter so the crap probably lays in the bottom which I clean after use. It also is very slow cutting but I have lots of time especially when I look at remaking some of my turbine parts. I also use a windshield washer pump but am going to find something that will run continuous as it heats up. You need something with a bit of pressure to blow the metal out of the hole or it will start to arc all over the inside.
I will include a picture of mine from an old drill press that went up in smoke in a fire. I may be able to help in some ways.

Ian, One setback to keep in mind is that a stick welder is constant-current Variable-Voltage, because it is relatively higher open circuit voltage (~75v ).
The voltage start to collapse or decrease whenever a current starts to flow, This is usually done with a loosly or variably coupled (shunted) primary to secondary on the transformer.
I am not sure what the requirements are for TIG, but it is not much use for MIG as MIG requires ~35vdc and constant voltage.
Al.

The plans looks god

Thanks Ian

So any one got any intention of building a DIY EDM ?

I would like to but I dont have the room for any more projects until mid next year :violin:

Russell.

Hi vulcom, that's a pretty crafty way of getting your electrode positioned with the x-y slides.
I wouldn't mind having a go at beefing up the specs of the plans I've got to get a bigger unit.
Once you know the circuit layout and requirements then you can start redesigning.
I think I would like to set up an X-Y table and drive them with two stepper motors so that actual "machining" can be done as opposed to plunging a hole out.
I'm not sure if this is the way to go as a wire cutter will cut out shapes very accurately.
Now if we had a simple design or amendments to the existing plans to do wire-cutting, that would be something.
Anybody know of the voltages and amps used generally and the wire specs to do a decent job?
At the moment I've got Tig on the brain, and that's one project that's top of my wish list, but I'd like to mull over the outline of a wire cutter to see if it can be made without too much exotic componentry, and also gather bits and pieces to have a go at along the way.
One thing for sure, it will be CNC to drive the tables, but as this technology already exists for foam cutters, I think it would probably suit wire cutters as well. Correct me if I'm wrong.
Ian (getting too many irons in the fire)

Hi machinefix, thanks for that, I reckon that is the most straight forward explanation I seen yet. The circuit diagram is great too. I don't have CNC but the core idea is all it takes to get the grey matter working.

Ian, thanks for posting the plans, have been looking at the Robert Langois design, nice to have another view on it.

Hi Sanjiv, don't get too frustrated with waiting for someone to make one of these machines, we're all too busy right now on other projects, but in the meantime we're collecting data and designs so that when the desire to actually make one occurs, then all the info' is there.
Nothing is stopping you from having a go.
Remember what Confucius said, "the longest journey starts with asking a few directions from well meaning friends and then goes on to getting some equipment at the local $2 shop and finally when the day arrives and your all fired up and rearing to go, Mum says "go and cut the grass, and then wash the car".
Ian.

Hi all, I see that deionised water is mentioned for use with EDM set-ups.
I get distilled water from my freezer when I defrost it and end up with two bucket fulls of "snow".
Usually I let the snow melt and bottle it in 'Coke bottles for use in topping up car batteries.
I get the idea that distilled water is preferable to tap water, due to it not conducting or shorting current by electrolysis and so boiling the water away.
This would be the opposite of the method used for producing hydrogen and oxygen in the HYDROX type gas torch where an electrolyte is added to the water to cause a current flow and so breaking the water down into it's constituents parts, E.G. hydrogen and oxygen.

Can any one mail me plane or any sort of detail to make home made EDM (of course small capacity). I am on the crucial stage and cant offered to buy.
My e-mail id is chinmay61076@yahoo.com.

Hi Guys,
I saw a wire EDM running today and it is very impresive.
I don't think an earlier question was answered but cutting 2mm plate it was using 110V and about 0.5amps.
They had the settings on the machine for higher currents.
It was orsm to watch and the 6M of wire reeling itself on one wheel reversing and reeling itself back.
The machine was very solid castings but I think one can be built failry easily.
There is no force on the job. It just has to be held.
It was 4-Axis too. You can make a pyramid from solid steel.
The job was held by 2 rails and water was pumped to either side of the job.
Spraying on the top and bottom.

I'd like to try and build one after the next 2 projects.

Cheers
Rod

HiThe machine was very solid castings but I think one can be built failry easily.

Rod, I agree, but i think easy is a relative term. you need very precise motion control and wire handling mechanisms. although there's no force, the the precision demands a rigid structure, ie no vibration. There's a good discussion in here somewhere, worth searching out. Roysol who posts here knows these machines inside and out and has outlined the basic mechanical requirements and challenges faced.

I'm going to build a plunge version first, right after i finish the sheet metal brake, grinder dust extractor, spot welder, one shot oiler for mill and lathe, power supply for the pillar tool, cnc lite mill, circuits and power supplfor for same and a couple of engines...god knows why i just ordered material for a V-8. i better live to 150 or I'll be leaving behind one confusing mess :D.

Hi McGyver,
Thanks for the info. I'll try and find the the discusion. It's a bit hard with the search engine here as it can't find anything when searching EDM.

I'd like to start on one after the milling conversion, the router, plastic vacuum molder, another milling machine and then a EDM.

To many machines to build, not enough time in the day, money and a nagging missis.

Cheers
Rodney

could you email to me as pdf...vry interested and would appreciate the knowledge!
Jimbo

cncsurfer@gmail.com

Having run both sinker and wire EDM's on the job... I can tell you it would NOT be a simple task to build a wire machine of more than 2 axis (basically a wire band saw...)

Sinker machines however can be made rather simple.

I am building Ben Flemmings design currently for my own use. It is about as simple as it gets. Well not as simple as Jon Elson's (the pico-systems link posted earlier), but it is rather self contained if you consider the tank/pump as a seperate unit.

really interested and appreciate if you can email the edm machine building guide as well!
joe_x27@hotmail.com

Hi Predator, I've got some pages from the Model Engineer that describe a small EDM for home construction and use.
I'll email them to you.
They're pretty basic stuff but if you want to learn about the construction and allied circuitry it'll serve as a start, and if your electronic knowledge is up to it you can adjust the components as you see fit.
Ian.

could i get you to mail them to me as well?


thanks

Hi Balwinder, let me have your email address and I'll send them direct to you.
Ian.

are these plans for a wire edm? if so i am in.

Hi 4th, the plans are for a conventional "peck & burn" type. More of a model makers toy but the principle is sound and if you apply the design & circuitry to a more advanced design it will give you something to experiment with.
Ian.

May I have the plans, too?

juhannus1@hotmail.com

Thank you very much.

Juhannus from Finland

Hi,

Can I get those plans to.

mjosburn@msn.com

Thanks,

Mike

Can't wait to try this one out.

Has anyone finished one of these yet?

And if so Hows it working?

Pictures?

Hi Miljnor, it's something I've wanted to have a go at for a few years but everything else got first priority.

The principle is simple, just peck away at a piece of conductive material with enough amperage and eventually you'll burn a hole through it.

I heard of someone who used an arc welder to get serious, so there's room for experiment as long as you understand the principle.
Ian.

Ive used industrial machines before wasn't really asking about how they worked I am more interested in the finished DIY project to see how hard it would be to do one of my own and to see how effective they are.

If you want to make one yourself, you'll have to know a bit about basic electronics, this way you can tailor the device to your needs, but more importantly once it's made you can find out why if it doesn't work.
Ian.

I know your trying to help, but I know enough about electronics to make one, and most likely make it work, but there is a lot less work to be done if someone else has done it before and worked out some of the bugs.

I don't need advice on how to make one (yet) just want to see a homemade/DIY one working before i even attempt it.

Mike,

Ben Fleming has written a book (http://homebuiltedm.tripod.com/) that has a circuit and directions for building a small EDM machine. There is also a yahoo group (http://groups.yahoo.com/group/EDMHomeBuilders/) for people that have built or are interested in building a machine based on his book. There is also a circuit board available through the group.

Also Dan Mauch (Camtronics) sells plans for a small wire edm cnc machine.

Alan

I'm not quite sure how this forum works.

Hi everyone! This is my first post so don't be too hard on me :0)

I can see lots of people asking stuff but not many replies??

If there are any plans for a tap disintegrator electronic or mechanical I would love them. I am running an old Charmilles F45 wire eroder. I have removed all of the CNC electronics and replaced them with a 6 axis system from Conqueror Designs here in the UK. The system is now PC driven with full 3D Graphics. All of the hardware is external to the PC with no dodgy software drivers etc., just a standard serial port. I'm simply using the old spark generator which seems to work OK albeit a bit temperamental. I can work to within about .005mm without too much difficulty. (Not too bad for for a country bumkin working in his backgarden, even if I do say so myself)

Like I said I'm not altogether sure how this forum all works, but I have mpg and jpg's of the system working, and I'd be happy to share any information I have on the subject.

Any tap disintegrator info would be great. I have some students who need an electro/mechanical project. I could probably start from scratch with them but why re-invent the wheel? If you guys don't mind helping out

Hi Botty, welcome to the board.

There are some home builder plans that were published in the Model Engineer some years back for a small EDM.

Post your email address and I'll send them to you direct.
Ian.

looking for plans if possible send it to me also thanks my add is mintukalsi28@yahoo.com

looking for spark genrator sercuit mine is not working acc to my need

hi ppl,can you give me a schematic of diy EDM home made?Plis i want to build one,
share to my mail,kybkyb7@gmail.com

Hi Balwinder/Kayaba

I'll forward the plans Handlewanker sent me, it's not the best design in the World but it should work. I have some students building one from the plans, we are updating the electronics. I'll post the final details of the changes to the circuits and mechanics, as and when we finish it.

Hello!!
Anybody have circuits and plans to make EDM machine with 555 to control the pulse.

Hi jsologuren, send me your email adress and I'll email you some I have direct.
Ian.

My E mail is sologurenjulio@yahoo.com.

Thanks a lot

alot of people asking for plans, but has anyone built one yet?


if so WHERE ARE THE PICTURES? ;)

Dear Michael,
I have a lot of development in Vision Machines, Laser Marking, Equipments with Microprocessor and DSP.
My WebSite is www.cymsystems.com, I have few machines with cnc that I make studing cnc_zone articles.

Please dont spam advertising BS on a public forum!

There are rules against it, and besides i don't see anything on the sight that is relevant to Homebuilt EDM.

Most people here don't want to hear about commercial machines, we want to hear and see Home built stuff. And I am not the exception.

hello friends:
I write to request them circuits (plans) to build a pulse control EDM. I allready made one, but is a metal desintegrator tap remover, with a series of Resistors and capacitors, but I want to build one better than this, with a modulator or a pulse control.
thanks and excuse me my grammatical erros, I´m not american.

Hi, does anyone have any real plans which they would not mind sharing, as I would like to make a EDM with 3 axis CNC control, regards Steve

3 axis CNC control....Hmmmmm.....the EDm produces the cavity etc by using a formed copper/graphite etc electrode, during which the end is gradually eroded away also, but the cavity formed is the shape of the electrode, unless you mean that the electrode is a square or round section and the form is produced by weaving around a shape under CNC control, which means then that all you need is the EDM circuits and the rest is normal CNC layout?

There are real plans to produce the sparking process, but they are pretty standard anyway.
Ian.

I would also like to build a 4 axis CNC Sinker type EDM.

When I say 4 axis I will use a spindle electrode holder which can function as an orbiter or as a controlled "C" axis - such as might be used to burn transfer ports in the cylinder sleeve of a 2 cycle engine.

3 axis helical moves with a rotating spindle allow "thread milling" type burning of thread forms in full hard materials.

There don't appear to be any functional public domain or open source plans out there. The power stage I will be using is proprietary, don't ask me to give away something that isn't mine to give. As to the control side I have high hopes that at some future point EMC2 can be adapted as the CNC control, but there are many unique to the EDM process issues which will still require much developement.

How do you do that? EDMs of the sinker variety have limitations. You can make threads by using a thread form electrode and a tapped greenboard guide. The Z axis has a rotary head that spins on center, and drives the threaded electrode in and out of the greenboard and into the work. Electrodes wear very quickly compared to a mill. I just don't see how you could make four axis work with a sinker. A wire EDM is different.

Hi Guys,
I saw a wire EDM running today and it is very impresive.
I don't think an earlier question was answered but cutting 2mm plate it was using 110V and about 0.5amps.
They had the settings on the machine for higher currents.
It was orsm to watch and the 6M of wire reeling itself on one wheel reversing and reeling itself back.
The machine was very solid castings but I think one can be built failry easily.
There is no force on the job. It just has to be held.
It was 4-Axis too. You can make a pyramid from solid steel.
The job was held by 2 rails and water was pumped to either side of the job.
Spraying on the top and bottom.

I'd like to try and build one after the next 2 projects.

Cheers
Rod

Anyone interested in making one of these can find complete details and drawings in "The Model Engineers Workshop Mag. issue 95-96 and 97. The article is by Peter Rawlinson.

This post has been going for a two or three years, has anyone got any comments/feedback on any particular design they have built for a sinker EDM?
Anyone built the http://homebuiltedm.tripod.com ?
Al.

I have mine 70-80% complete.

It would get done faster if I was able to spend more time at home, but I go where I am paid to go...

I have Ben's book and his PCB - I much prefer using a real PCB vrs perf board or attempting to fab my own PCB.

If I were to my own I would likely use a bigger H-Bridge chip to allow slightly larger servos than the ones suitable for Bens Drawer slide design.

Many members in the yahoo forum have reported successfull builds.

The Key thing about Ben's book is he gets into the details of using the EDM and preaches the gospel of proper flushing... Its way more than a simple how to writeup.

Also - Some day a pulsed EDM follow up book has been promised. :stickpoke

I have both the Langlois and Fleming books. My head is finished but was built with a stepper motor. I ran into trouble making a decent PCB for the stepper control though, so it has sat. After finding the Fleming book with a simpler servo drive, I decided to incorporate both designs into one ideal unit.

Langlois goes into deeper detail for controlling the burn with a capacitor bank that includes larger capacitors. Fleming has the simpler control and goes into detail for an EDM tank. I have everything I need except a PCB board for the control. Because I already made a precision stepper driven head, I'd really prefer to build Langlois' control, but will probably bite the bullet and find some servo that I can cobble to the stepper mount just to get it done.

dear all

please I hope to built EDM machine any body can help me for this project

thanks in advance

Hi Gamal, post your email adress and I'll send them to you direct.

They were posted previously in the first one or two pages on this thread.

Ian.

Dear IAN

thank you for answer my mail is (yyoonnes@yahoo.com)

thanks

gamal

I would like to get the plans. By the way, I can offer a book from a Russian that invented the EDM where he explains all the different factors affecting sinking EDM. By the way I also would like to know if any of the plans include an EDM by pulse (not R-C circuit)

moltenig@hotmail.com

Hi gmolteni, The plans are for a straight forward die sinker type that uses a stepper motor drive to peck the form out controlled by the circuit.

If you are familiar with electronics maybe you can modify the circuits and post a plan for an update to the system.

I'll send them as is to your email adress.
Ian.

Hi Handlewanker

Can I also have one of your plan please?
my email address: stchen99@gmail.com

Thank you very much for the plans Handlewanker.

I found most of the information about EDM very light, not going deep on practical information.

I uploaded a very interesting russian book (english edition of the book) about sink EDM http://www.esnips.com/web/mecanica3

Although the book is rather old, (in fact is one of the first scientifical studies about the subject) is very interesting the way the matter is covered, perhaps it would be useful for someone else.

I was looking a PDF named "edm-power.pdf" but the output of 7555 goes to nowere ...
something is bad there :(

See you, and thank you in advance for your plans

The first EDM I ran was one of the first commercial EDMs out there. That thing had huge vacuum tubes like an old radio station. It appeared to work on the low voltage/high current principle. One feature that I noticed was the "automatic" feeder which used some sort of sensor on the current where if it made solid contact the tool would back up until proper arc was maintained. I'm told this was how early carbon-arc streetlamps worked.
I stumbled across this thread looking for a project and I'm pumped about this one. Stay tuned for further developments.

Personal info: In Jan 2009 I retired after 50+ years in the machinist/tool&die trade. I find I still have to build things.

Thank you very much for the plans Handlewanker.

Hi Predator, I've got some pages from the Model Engineer that describe a small EDM for home construction and use.
I'll email them to you.
They're pretty basic stuff but if you want to learn about the construction and allied circuitry it'll serve as a start, and if your electronic knowledge is up to it you can adjust the components as you see fit.
Ian.
Hi Ian,

I am new to this forum. I would like to build this edm too, could you also send me your design from the magazine? Here is my email address: jimmy_linggar@yahoo.com

Thank you in advance.

Btw, is this design the same as the one you have attached in the earlier post (with 7 jpg pages)?

greetings,
jlinggar

All you guys got the plans, has anyone completed it?

Hello Handlewanker,Please send a copy of your plans to my email address:santafesonido@hotmail.com tanks a lot

Hi Handlewanker,

May as well add me to your mailing list.

I built Ben Fleming's Servo type sinker generator but am looking into other generators that can put out more useable amps for larger total electrode surface area.

May I also ask for your plans ? My email isabelo@gmail.com

Hi Skullworks, send me your email adress and I'll send them direct to you.

The plans are for a DIY model of quite modest ability so if you want something with a bit more grunt, maybe this is too "Model Maker" type.

Hi Santafesonido, I tried to send the plans to your email adress but got a message saying adress couldn't be found, I'll try again.

If that fails, the plans can be found on the earlier posts on this thread.
Ian.

Thank you handlewanker for emailing your plans.

Here is my sinking EDM. For a downfeed I used a common 90 VDC gearmotor.
A PLC monitors the spark voltage and has the gearmotor go FORWARD/STOP/REVERSE for feeding the electrode.

Power supply plans came from:
"Build An EDM" by Robert langlois

Available from the Village Press, Inc

The rest was built from my head. I have no drawings of the hardware.

I saw your pic of the coupling keyway cut with EDM machine. How would you compare if it is cut with a slotter or shaper ? What is the tolerance for fitnest cut with EDM ?

That slot or keyway was a blind hole. Not likely a slotter or keyway cutter could do it.

EDM always has an overburn of around .006 per side so you make the electrode undersize accordingly.

Jim

What is the depth of the blind hole and how long did it took the EDM to finish ?

Depth was 1 1/2 or 2". Probably took an hour or more to burn the slot. But, the machine is automated and shuts off when the depth has been reached.
