Chris So do they use some needle roller bearings that run on the lobes or something?
I could make that work I reckon. I already have the massive big angular contact bearings and if I can make the lobe part OK then I'm away. Add a big clamp to hold everything rigid and tight for milling and I have a decent commercial quality 4th axis. Might use a 1kw Chinese servo drive on it. Then add my harmonic drive I have for a 5th axis and I'm into 5axis territory. Just need to learn how to do that on linuxcnc haha. My bearings have a 100mm ID and I'm thinking that would be good for a hollow spindle maybe.. Not that I would need one that much.
