Re: [CAD_CAM_EDM_DRO] Commercial EDM capacitance ranges

Very good information thanks.

Can you adjust the voltage level your machine puts out when it's open
circuit?

I assume you can adjust the on and off time of the spark?

The water versus oil in the wire makes sense now. The wire is 'wasted' so
you don't
care if the water causes more electrode errosion.

Seems to me though for the home shop or hobbiest, using oil instead of water
to make that wire
go further would be a good thing to do. I've priced EDM wire and it's not
cheap. But neither is
anything else that has EDM stuck on it. Kind of like Mercedes and airplanes
<grin>.

thanks,
Larry Edington
( so I won't be confused with the other Larry E. here )
