THese would be tiny, but highly detailed parts, think N scale model trains where a rivet would be about.005" in diam and about as tall. I would mill in plastics, brass and alum and wax as well. 12,000 RPM would be OK, to start with anyway. I am a total newbie to full 3 and 4 axis machining.
[For features that small, you might want the faster spindle option. Running very small tools requires very fast speeds, if you want to maintain reasonable feedrates.]
THe above is hobby/business. I'd also use it in my primary business where I do prototypes and mechanisms. I have a Prototrak Bridgeport and this would be for the stuff that is too small and to supplement it.
[That makes sense. It won't take a cut as heavy as the Bridgeport can, but it will do finer work.]
Can I use Onecnc which I own to bring CAM into it? From what I read they use a modified version of Mach.
[If OneCNC has a Mach3 postprocessor, then it should work well right out of the box. If they don't, then you might have to fiddle with a generic Fanuc post to get all the G-code functions working right.]
How would you compare it(if you know) to the Neo and the Minitech machines?
[I don't know much about those machines; the Neo is made in the UK, and would probably cost a lot to import. Minitech has a number of different options, and the ACT would be comparable to the ones in the middle to upper range. But I'm pretty sure it's less expensive.]
Thanks again,
Paul
