Thread: Wire EDM machine

For testing purposes (and because I wanted one) I tried cutting a tiny screw-cutting tool for my lathe on this machine. It cut a 3/16" high-speed steel toolbit with a 1mm long 47.5deg tip (which some people might recognise as the thread angle of a BA thread) basically by cutting straight across with a deviation to form the "point" of the tool. Took around 5-10mins to cut - wish I'd timed it but I wasn't really expecting it to work at all! I can see a use for this machine for myself, cutting form tools for lathe work directly into HSS. According to one guy I spoke to, EDM works well with tungsten carbide as well.
