Just a few words to compliment Ben on a really excellent design. I'm very impressed with this little machine, results are superb and it's a real asset in the...
I would also like to say that it works great! I've tried various electrodes (haven't tried graphite yet) and this thing eats through metal like it was butter....
I use copper in the hole poper, on the wire edm and some times on the sinker to hit that really fine finish. Other then that I use Poco 2,1 or AF graphite. The...
... hopes that the new pulse book will be out in the spring or early summer 2007. It is not tech problem were fighting but health problems. This book is a two...
Hi, new to the group so I just thought I'd say hello. I just ordered my copy of the book and I'm looking forward to reading it. I've built two cnc machines to...
Chris, yes, but there is no provision for it in Ben's design. Also, the controller will need additional controls to control the arc in the X-Y axis. A simple...
Hi Guys, I would think a moving electrode (excluding wire edm) would possibly be a problem for a graphite electrode, I mean if you apply force to the graphite...
... but you don't apply any force. Graphite electrodes are frequently used with orbiting heads in industry. ... That's the basics but not the only way to do...
I've already built a couple of cnc machines. I don't understand why you couldn't mount the electrode to the gantry and pass it over the material. As it erodes...
I haven't seen a home built one, but the EMC doc's say it includes cnc code for controlling an EDM. The cnc EDM's I've used will burn any direction and there...
... for machining complex shapes. ... The system is single axis, it is not designed nor is it suitable for CNC use no matter what the axes used. Graham...
... The problem is that as you get the deeper the direction you need to move the electrode to maintain the spark gap may be in the x,y plane rather than up and...
... it's single axis as described in the book. that doesn't mean the design couldn't be modified/expanded on to make it usable for cnc. Chris Reynolds ...
Fortunately, your objections have no power to make something impossible. With a separately powered rotating head, and 2-axis CNC controlling an x-y table,...
I currently have a 4 axis controller and four stepper motors that I could put to use on a new cnc machine. So it would seem that there are some really cool ...
There are lots of types of EDM's The spark gap doesn't so much need to be a given size, as much as it needs to be kept open and at a proper distance to let a...
well I got my book today and it's been an interesting read so far. so to get back to my question about using it to do 3d milling I noticed something...
any friend have circuit diagram of power supply required for edm which can be made at home? ... Stay in the know. Pulse on the new Yahoo.com. Check it out....
Ben's book has all the schematics in it that you'll need for the edm machine. Chris Reynolds http://builderofstuff.com "Computers are like air conditioners -...
you can get it from www.lindsaybks.com that's where I got my copy Chris Reynolds http://builderofstuff.com "Computers are like air conditioners - They can't...
from what I've read so far, yes I don't look at any design as the end all be all of something, rather I like to look at designs as starting points for my own...
Guys, I've just posted some pictures of my recently built PC Board in my "MaximumBob" folder in the Photos section. I was genuinely inspired by Nick Jones' PC...
