i love finding slight technical inaccuracies in something i’ve written and covertly (and usually sloppily) giving that inaccuracy an out through some convoluted means instead of just correcting it purely to thwart a Type Of Guy i anticipate would comment smugly about it who also does not exist nor could exist since people correctly do not read what i write more closely than they would a children’s book. this quirk is something we italians refer to as La Schizofrenico
good article. highlight:
“Due to its complexity, the roller screw is a relatively expensive actuator (as much as an order of magnitude more expensive than ball screws), but may be suitable for high-precision, high-speed, heavy-load, long-life, and heavy-use applications.”
ball screws are already bonkers expensive. precision acme threaded lead screws are just regular expensive. i only ever hear about ball screws being used in modern high-end CNC machines. what insane use case decided ball screws weren’t enough
