I think a low cost EDM would be perfect for fabricating small watch parts. Stupid accurate, no forces on the cutting head, could easily be desktop sized (at least for a work area of a few cm) and very quiet. Can only cut metal, but that's a pretty decent compromise I think.
- anfractuosity 9y agoI just found https://www.geartechnology.com/issues/0610x/edm.pdf https://www.geartechnology.com/issues/0610x/edm.pdf which seems to confirm that EDM has been used for watch gears - "Wire EDM can be used for micro- machining applications, including the gears found in watches" Do you know of any low cost EDM machines out of interest?
- Hasz 9y agoI've actually been playing around with designing one, but lack the free time to do so. I have a couple of Fusion360 models set up with commercially available parts, but I don't have a physical prototype yet. I'm planning on setting one up this summer. I know of nothing available commercially at a reasonable price and size.
