Build an EDM

Amazon Renewed Refurbished products with a warranty. The tank is a lot smaller in person than it looks. These items are shipped from and sold by different sellers.

Especially considering he never actually built his circuit. That will also allow all of the tabs to fit in more thoroughly, helping the assembly keep in square and slide more smoothly. When that electrode is close to the metal and the potential is high enough to ionise a path through the dielectric fluid, an electric arc gets created between them, taking out a chunk of your workpiece. Other than hardcore machinists or mechanical engineers, few people know langloi it is, which is probably why I’ve never seen one used for milling PCBs.

The PCB holders at the bottom might be changed builld little before I build buils, but the idea will stay the same. Does this project spark your interest?


It goes through a 2: I grabbed a cool-ass box. That is made more difficult by the hackspace being in a state of flux at the moment after having our lease unexpectedly terminate recently. A little while later, I got a frantic text message, “Pick up your shit!

Useful for museums and schools. I’m using components scavenged almost entirely from my hackspace’s parts bins, however, so I am limited by what I can find. Description EDM is often used for milling very hard materials, or very deep, thin holes. ComiXology Thousands of Digital Comics.

I put all of my polished-ish stuff up on my website leftbut I’ll be experimenting with this format for a daily-blag type thing.

Through a completely offhand comment that someone made about finding a PicKit in the dumpster a couple days later, I rushed over and did some diving, recovering most of my project. If melts and catches fire, put it out, okay? Your Email Remember me. I need some sort of analog readback at each of the stages. If I come across a transistor that is slightly faster, lower Rds this is 5 Ohm – too high!

It needed a bunch of rework, anyway. Except for the power output stage, I couldn’t find that board. Very little drawing out of stuff beforehand. I guess a year-long hiatus is enough, right?

Heading down there a couple days later, well into the packing effort, to grab my project box, I couldn’t find it where I left it. Afterwards, the top flips up, and those PCB holders are angled so that the oil drips back into the tank. Usually or often, I should say they’re going right to 0V, so my natural inclination is the drive the gate voltage using ground as the reference. How well this works will depend heavily on how well I can filter out the noise from arcing.


Electrodes are on the right. Well, I need to, to know what’s going on during a burn. There’s a problem loading this menu right now. I needed dimensions of all of the parts to mount and design around this anyway, so a couple hours with their laser cutter files produced this:.

Would you like to tell us about a lower price? English Choose a language for shopping. Your Password Forgot your password? It uses three TINY!

Basically a spark welder to remove material.

That double-ensures that this portion will eventually be replaced, probably with a CNC system of my own design. Already have an account? As it stands, I have a clean 5v rail and a dirty 80v rail. It’s only 60v my final circuit is 80vbut the principles don’t change with the lower voltage. Eventually I may need a 12v rail for driving motors, but I’d like to put that langlous as lang,ois as possible.

And nothing blows up! Probably redesign at some point to use some threaded rod and homemade anti-backlash nuts.
