The magic of EDM machines
The other day we were asked to remove a section out of a valve. It’s not a huge valve but milling it would’ve been difficult all the way to the center so we put it on the EDM to blast out the side to make the inside visible. through to the stuff on the inside. Here are the images.
This was all burned at 150 amps which is max for this machine.
Nothing crazy interesting, but I thought it may be neat.
