Electrochemical machining

[mingki]

I am trying to build an electro chemical machining device.
Could you recommend me some good tutorials on how to build electro chemical machining device?
Please help~!

Googled for Electro discharge machining and found out this:

Thanks a lot. I will also study EDM.
But now, I need to build ECM machine.
Could you recommend me a tutorial site for DIY EDM machine?
Also, My workpieces are made of SUS316L, monel, Inconel.
In this case, I wonder whether the electrochemical machining could work...

Can't help much, not my field of expertise. I just wanted to outline that a google search can provide some good informations

This is an extremely broad subject to be addressed in an internet forum. It might be helpful if you could provide a bit more about what type of electrochemical machining you are wanting to do and why.

Hi, I hope I could build ECM machine to process(cutting, grooving, milling) stainless steel, inconel, monel material without affecting their mechanical characteristics and chemical properties. But, I just realised that ECM doesn't work for non conductive materials just like my above mentioned workpieces. In this case, EDM could work? I think EDM method generates heat to he material, then the mechanical and chemical characteristics of the workpieces will be changed, right?
I think I am lost here..

Does ECM work for steel alloy like inconel, monel, hastelloy?
how does it work with Stainless steel?

Those are all metals, they are conductive. We EDM 304 stainless steel all the time, I think those other metals would not be a problem. It is usually done on a bath so the work piece sees only very localized heating.

ECM on those exotic alloys will require quite a specialized knowledge of chemistry. We have a part photo etched from Nitronic 60 and only a couple of suppliers have done it successfully. The ones that can do it have made millions of parts for us, the others swore it could not be done.

Thank you.
