Build your own EDM machine.

Custom CNC mills can be built from off-the-shelf parts. EDM is different. The arc generator is normally not sold on its own, because it has to be designed for the machine it runs in. BaxEDM makes an adaptable generator, so engineers and serious builders can finish a custom wire, hole or sinker machine without designing that generator from scratch.

What’s included

Order any of these by email: sales@baxedm.com. The BX17 is the previous generator. It is no longer sold.

Why it exists

The generator was the missing part.

The market for custom CNC milling machines is large, both professionally and for serious hobby builds. For EDM, the arc generator is the hurdle. It is a complex piece of hardware, usually designed into a complete machine, and not offered as a component.

BaxEDM’s generator is built to drop into a custom design and still produce professional results. With that part available, a low-cost custom EDM machine is a mechanical and controls project.

From the people running them

“So far I have machined with the generator for 4300+ hours without any problems and have been able to make many parts.”

“Highly recommending this generator unit. It is built by a professional and it delivers what it promises.”

Jaakko Fagerlund · Suomen Tiirikointipalvelu

“I spoke with Mike by email on a Saturday morning, and on Saturday afternoon he called to say the firmware was updated. I bought another generator for my work.”

Gordon Kirkwood · SRI International
