I've few questions in my mind regarding EDM that if we use micron size diameter electrode (say of size 200 mm or 0.2 microns),
1. How to hold one end of the electrode without deflecting the same?
2. If we are using Hollow electrode, how to pass the dielectric fluid through it from the other end as the electrode would also be rotating?
3. Say if we use chuck kind of arrangement to hold the electrode, how can it become possible to provide dielectric fluid through other end of that chuck, without causing any leakage of dielectric fluid?
Please suggest some ideas...
I think the diameters are a bit confusing, because 200 mm diameter can be very neat clamping. For diameters less than 1 μm, you have to consider how to get these wires. Normally one has a wire that dilutes itself successively.
The questions you ask are already very justified, but many users also see this as their know-how. For electrode lengths of up to 1-2 mm one should find very fast solutions. It is only really critical when the aspects go well over 10.
