You are still on my ignore list -- but since this is an important point, I will pay you a modicum of attention:Nice thread. The only thing wrong was the head line of the thread. He didn't build it himself, just assembled a bunch of off the shelf parts. https://baxedm.com/
I cringed as I watched him thread the electrode into the chuck. The last thing I think one wants to do introduce bends into the electrode. This would likely add considerably to the hole tolerance.but diameter not exact...
That's not so easy to do with hardened parts - or even carbide parts.one could follow up with standard
drill and wind up with all dimensions dead on.
But there are a few of us doing it on this forum, and many more doing it world wide.Integrating some purpose-made parts and instrumentation into a final system saves a considerable amout of time and effort -- and the project would probably be next to impossible to complete otherwise.
But the final "product" is home built -- in my ever so humble opinion.
As some one who did EDM for a living for quite a few years, I can tell you that isn't true. It is done to size by changing the size of the electrode. Meaning you adjust the electrode size by what is called the "over burn", the amount the spark takes out. You can easily get drill accuracy and with experimentation reamer accuracy.Whats interesting here, case where hole is drilled perfectly strait thru
side of bearing, but diameter not exact, one could follow up with standard
drill and wind up with all dimensions dead on
Then how and why do you continue to respond to my posts?You are still on my ignore list
Here's what I'm thinking: I have an airless paint sprayer just like the one he's using in the video. I wonder if I could use the water jet to do some cutting of softer materials.
