Have you tried this?

Yes I have tried them.

Maybe you need to change your fluid...

...or maybe track down and ask one of these guy's....Ken or Tony Rolfe...

I think you have the manufacturer name wrong possibly, they seem to only do contract work....is it possible?

Hello Johan, the company still exists, they are based in Sheffield, UK.
Here is their Website address Erodatoolsltd.co.uk
Their telephone number is ++44 1226 763725
Hope this helps.

thanks for the reply but it is not Arodatools.

The description on the machine is:Aroda.

N.E. Eroda Machinery Ltd, Electro Discharge Equipment.

Unit D Taoman street, Wakefield WF1Sou, Yorkshire.

I do not know if this is helpful.

Regards.

I would try these guys....

Hi Johan, in your opening post you wrote "Can anybody please help me to get a wiring circuit diagram for an Eroda EDM" using the word Eroda, now you are using a completely new word " Aroda".
Please confirm which machine you have, maybe a foto of the Data Plate information would be helpful !

Please excuse my finger problem, it is ERODA

They have gone out of business three times, and each time they change the name slightly, and start a new business...

N.E. ERODA MACHINERY LIMITED, 10 Sep 1973 - 21 Mar 1991 ...

ERODA HOUSE LIMITED till 2011

Eroda Tools Limited...

If I were to guess, I would say the private company owns the public company/companies that keep failing...this is probably designed as a liability dodge...so good luck trying to deal with them directly...what you need is a specialist that can redesign or replace the part/or parts that have failed...would be my advice..or you can keep trying to figure it out yourself...this all depends on financial means at your disposal...

Although the wiring diagram might help: what you really need is the circuit diagram for the pulse generator PCB.

Just looking for any EDM pulse generator circuit diagrams on the net might help.

But there might be a short cut: does the PCB have any Aluminium Electrolytic capacitors on it? If so replace them. Exact equivalents will do, but if you can get higher temperature/longer life versions they will last longer. Better still would be to replace them with equivalent voltage and capacitance MLCCs (MultiLayer ceramic Capacitors) but this might be impractical.

This "fix" works for loads of "power supply" type problems. Often you can spot the dried out capacitors because their cans are "rising up" off the PCB.

Hi Johan, I contacted the company in Sheffield to see if they could help but No-Go unfortunately.
Here is their reply.

Hi Norman,

No unfortunately that was a different company to ours and we are not affiliated in any way (there were two separate companies set up by brothers who had fallen out). Eroda machinery has long since been out of business so sorry but we cannot be of any assistance.

Best regards,

Caroline Healey

Works Manager
If I understand your orginal post the machine works but is slow.. maybe you could try to find out which parts / components would make it slow.. I don't recall if you said how old the machine is, maybe when it was built, it was the normal speed ?
Guess you can try Randall's suggestion !

Looking through the indexes of the various EDM books that I have:

Cyssau's L'Usinage et le Durcissement par Etincelage lists an "Erodomatic" machine manufactured by a company named Wickman in England. No wiring diagram.

Spark Machining published by The Machinery Pubishing Co., Ltd mentions the same machine, or family of machines. No wiring diagram.

Neither entry mentions running "too slowly" in its troubleshooting section.
