14mm ballscrew + nut for VMC260

[John S]

One thing to remember with fine pitched ballscrews is they have a shorter life than courser pitched ones due to less ball being in contact with the screw and nut.

Hi John,
I am not too wory about the life time... I only use my mill once or twice a week...
If I replace the ballscrews with new ones, they will last a life time for me. :-)

But thank you for the info!

Did anyone find a good source for threaded ballnuts?.. my boxford Z Axis Ballnut just spat its bearings out... so im looking for a source of threaded ballnuts myself that wont snatch my arm off...

the reason i say go for a larger pitch (5mm), is you get a far stronger ballscrew which will give probably 5 times the life of the 2.5mm pitch screw. These boxford ballscrews are a common fail point, and are just not upto the job.
