Title: Roller Screws
Post by: Arbalist on April 19, 2014, 03:37:48 PM

Shame the Chinese don't fit stuff like this on their milling machines! I've seen ball screw conversions but this is perhaps even better?

Interesting stuff. It's a shame some enterprising soul in China hasn't come out with an affordable easy to fit "upgrade" kit for my VMC Mill!
