What would happen to a EDM if the fluid got to flash temperature? If you break a piece of Stainless Steel. Ben Fleming’s design is very heavily based on Robert Langlois’, but he adds a very clever design to pump and filter the dielectric fluid. May be wrong on this but I’m sure i have seen references on t’internet about the design using some voltages generated direct from v mains and not from an isolated supply.

Something very simple, suitable for making holes and removing broken tools like taps. A new, unread, unused book in perfect condition with no missing or damaged pages. Fun to make, fascinating to use — perfect results! Electrical Discharge Machining EDM is a bby that uses electrical discharges from an electrode to erode langloiis electrically conductive material.

I think they are called a tap out or something? I built an EDM from the Langois book. But you’ll need to also resize everything downstream: They just don’t seem as prevalent as they used to be.

If I hook up the primaries in paralell and the secondaries in paralell and connect to V to the primary side, I get 60V output.

You can check him out at: Robert Langlois’ book a collection of the articles published in HSM is excellent — it explains all the EDM concepts and how to calculate the yb for the power resistor, the various RC settings for speed versus surface finish burns.

One thing to note, capacitors, they hold energy, higher voltages mean higher bukld of getting fried.

There was a problem filtering reviews right now. Well I’ve stumbled around My junk collection and came up with a 1KVA transformer with two primary and two secondary windings primarysecondary. After reading the authors explanation, I now have a decent understanding of all of this, and could see applications for stepper motors in other machines that I may build. I should have guessed this due to the fact that the booklet is only fifty something pages.

That’s joules delivered in a millisecond, a peak power of horsepower if it were continuous.
