Warning: n00b ? - What can you tell me about an Elox Electron Drill?
Interested in potentially buying one of these. I do repair work and get a fair amount of busted off bolts and drill bits, if welding something to it won't get it out I usually end up digging it out piece by piece with a carbide bit in a high speed dentist-style air drill. EDM seems far more glamorous than sweating over a blind hole with an air drill.
Seller doesn't seem to know too much about it (hasn't used it from what I gathered), workability is questionable but price is right so even if I have to do some fixing/troubleshooting I can afford to. Bear in mind I know very little about EDM's and tap burners/disintegrators, I bought a couple DIY books and was thinking about eventually building one for kicks but at the price this one is going for I would be time ahead to start with a solid base rather than sourcing all the components and building my own.
I guess my main questions are:
- What power requirements does this machine have? What can it output in KVA?
- what would this machine use for cutting fluid?
- how big/how small can this machine go for electrodes/diameters?
- what kind of electrodes would this machine typically use? For disintegrating taps, bolts, drill bits etc is there any distinct advantage/disadvantage of certain types of electrodes?
- Could an extreme DIY'er add a portable head like the newer electro-arc machines have for doing work on-vehicle?
Thanks for the help
Anybody? Bueller, Bueller?
Can't really help on that make, but I own a Cammann disintegrator which works great...and fast. The smallest elec. I have is .040". Mine only goes up to 3/8'' electrode, but that doesn't mean much. For example: I burnt out a 1½-6 tap with the 3/8'' electrode. Took two passes side by side. Piece of cake. It was about 2½'' in the hole and the top was exploded like glass. Didn't matter, just zipped right through it. You can hear the difference when it clears the bottom end of the tap.
As for coolant, I use ""Discool". Cammann's own mix. Works good. You can use graphite electrodes, but I use 100% pure molybdenum. They last a bunch longer. One thing that does suck, is after you burn out a steel stud in an aluminum chunk, you've still got to dig out the threads. Ain't corrosion fun!
Setup can be a challenge, but I tell them in advance that this ain't cheap. I won't even consider the job for less than 100 bucks. If they whine about it, that's fine too. This company makes a portable machine, but mine is not. Plus, I don't want to get into that, anyway. This unit was 460V, but all you have to do is change the taps to 230V and different fuses. The output on mine is 15KVA.
Anybody else know anything about these units before I pull the trigger?
Googling elox brings up a company called "EDM Zap" that services them, anyone know anything about those guys? Do they own the right to Elox now, if not who does? I'm going to call them tomorrow see if I can get ahold of a knowledgeable tech or manual about this machine.
Appreciate the info but I'm in absolutely no position to buy a new tap burner. Do you know anything about the old used one I'm considering purchasing? What parts can you get me for it, your website says you have all manner of EDM parts?
