Hi All:
I need to burn some skinny copper electrodes for a sinker job, and I'm trying to figure out how I can hold them to cut them on the wire EDM.
They're only about 0.200 diameter, one inch tall and six lobed, something like a supercharger rotor.
They can be cut in one pass...no need for skim cuts.
I tried tapping a 2mm hole in the center, wiring most of the profile and putting a strap clamp across the part, then bolting it to the waste block with another 2mm screw and finishing the cut...it didn't do badly, but it's not perfect either.
I've thought about filling part of the gap with quick set epoxy and putting a pigtail strap across from the waste block to the part to maintain conductivity and then finishing the cut.
Have any of you tried anything like this?
Cheers
Marcus
