[CAD_CAM_EDM_DRO] rotating nut/ rack and pinion drive

Doug and all,

Just a couple quick links to rotating nut and rack drive manufacturers.

Of interest is Thomsons new RN series of rotating nut
ballscrew drives. The hollow ball-bearing nut housing is
integral in the unit. The lube starvation (due to grease
slinging) issue is dealt with by recommending a pressure
oil lube. I would have no problem specifying a fully tested
system like this... but I'll bet the price is out of this world!

The other is a manufacturer of racks for gantry machines:
