Hi everyone,
I am a newbie to EDM machine and have zero background about it.
I just did several run using cooper-tungsten electrode to drill a hole on a inconel piece with 3/4" thick. I followed the operating procedure on the manual book and the results came out not quite right. If anyone familiar with Elox Astra 50 please give me some advice. Thanking you in advance for your help!

Advice? My first advice: Give a clear question. Oversize, ugly, not straight? What does "not quite right" mean?

[EDM_Fixer]

What size hole? What material? How thick?

What settings you running?

Whats the burn look like?

That will give us a start....later Jim

A little more detail please.

What size hole?

Were you using a roto-spindle and a flush-chuck?

Examples:

Were you using a single-hole or a multi-channel tube?

Standard or reverse (draw) flush?

What were your power settings?

What, exactly, do you mean by "not quite right"?
