Good Day People.. I got a question regarding the design on the book.. Is the vertical movement speed/feedrate Pulse Width Modulated controlled or regulated at...
Thank you for accepting me into your group, I all ready have the How to Book which I purchased some months ago and put it on the must do list, I live in the UK...
Just pure 12 volts, either off or full 12 volts up or down, polarity reversed of course. Are you sure you'll be able to get, or on the other hand I'm pretty...
... fine > enough movements to work effectively as an EDM. On industrial machines like mine, hydraulics is the way to go - and ten thousandth of an inch and...
I guess it just shows how little on the subject I really know. I'll have to chalk up another one for hydraulics though, I already was amazed at the shear...
The DC motor runs full speed down until the arc is established. Once this happens you will notice (if you connect an analog meter across the motor terminals)...
Not trying to get too off the subject of Mr. Flemming's design, but just as a general point of interest... I know we have at least a few EDM "pros" who follow...
... Tools on real machines can weigh many kilos - one up for hydraulics. Hydraulics can apply a lot of power in a very compact way - so the heavy tool can be...
... No, its a bi-directional cylinder, about 1.5" in diameter, that acts on a very traditional machine tool slide. ... England went from our old "LSD" currency...

Makes a lot of sense to me now too!  Thanks Al for asking that question! Thanks Steve I would have never guessed it could operate that fast. Jim ... From:...
Now I can see said the blind man! Thanks for the run down Steve! For the work I anticipate doing this little gear motor head will be just fine for me. I...
The tremendous force for which hydraulics are usually known is secondary in this application: you are right that there is next to no force exerted on the...
Thanks guys, for the insightful responses. That certainy answers my question. I guess if I had thought that through it might have been obvious. I have heard it...
In my opinion the application of hydraulics to replace in EDM servo heads is just attempt to make something more complicated than what is really necessary to...
This thread started when a reader who owns an old commercial EDM that has a hydraulic ram wanted to know if the control system in this machine could be made to...
Umm, as I understand it, many commercial EDM machines DO use hydraulics for many of the reasons outlined by some of the other posters. I asked the question...
Ben: Regarding your & EDM circuit. I'm helping Blake build his project box. As a long-time electronic hobbyist, I understand your circuit operation. Some...
... Er. Most of the big EDMs I have seen are hydraulic It has to be said that a properly running modern edm is it isn't really "pecking" terribly much, the ram...
... this happens you will notice (if you connect an analog meter across the motor terminals) that the motor is tweaked with a small (analog) voltage, usually...
I beg to differ, this site is for the builders of Ben's EDM machine according to his book. We know you are an expert and have operated industrial machines but ...
... I think we will have to agree to differ, especially since Ben has been joining in. Of course we have to realise that, for a scratch built hobby EDM,...
I did not install limit switches to keep the design as simple as possible though there are several benefits of using such switches as you know. In the new...
I don't have a problem with discussing the EDM related hydraulic rams. I don't mind any topics related to EDM being discussed here that in part is what this...
Pity you don't want to publish the postcard. It's brilliant prose which far out-Waughs Evelyn Waugh for acid humor. ... From: Ben Fleming <bnf@...> To:...
