Re: [CAD_CAM_EDM_DRO] Handwheels on a retrofit? Why!? was Re: software questions DRO

I'm referring to the standard 5 TPI on a Bridgeport. Yes, Bridgeport sold and sells as a factory option, the installation of ballscrews. They are meant for CNC use. I dont know how you can label a fact a "wives tale".

This isn't usually true, more like a wives tale. If your ballscrew
pitch is much more than .5 turn/inch it won't backdrive. Most mills
are several turns per inch. If this wasn't true Bridgeport would not
have offerred a manual mill with ballscrews. Check out the ballscrew
company web sites.
