Hi guys,
In my first machine i used 12mm threaded iron rod for transporting the gantry. The nut is made of a copper-zink alloy (Messing, dont know the English word).
It works, i compensated backlash by means of two springloaded nuts, no fancy stuff. But it's no ballscrew.
So i started thinking of using Teflon. Dont know the English word either, but it's the stuff used in cooking pans. (duh...)
Anyway, did anybody recently try this with teflon? It's tough, it's wear and heat resistant and it slides like...well, more like a ballscrew than copper-zink does.
Being tough, it might be hard to drill accurately, and tap 12mm thread into the hole.
Anybody want to share thoughts about this? A beer for the first reply!:cheers:
Thanks,
Ed.
