need to find ballscrews to replace the leadscews on my mill. anyone have any lying about? who makes the best ones out there and the best value(quality and price)

I had mine made custom from rockford ball screw, $800.00 for x and y, plus there yoke. Installed pretty easy.

Try Hiwin, they seem very inexpensive. Like 300 to 400 per screw. They claim to be a supplier to Bridgeport and that's why they are so cheap.

[rwerner518]

do you still have part numbers for the material? and the yoke?

[DRD]

Go to rockforballscrew.com on the web, all the info up there. They have tons of drawings on hand, and wil make what ever you need. the whole kit was $800.00 plus shipping. Also, I used elrod machines x-y motor brackets, plain out awesome, they come with new bearings and all hard ware.

Just bought Rockford X-Y set with yoke retail $650.00 and the angular dearing set is $105.00 but this is not really an upgrade at least on the later style BPs but bearing headquarters is a distributer and has a slight discount. I think if you can live with a maximum of .002 per foot this is the best deal in town. mach3 has screw mapping for cnc.

Just did an install on a set of rolled screws from Hiwin. I don't have the numbers here with my at the moment but a quick call to them will answer all your questions. Call them and talk to Jason in engineering ( I don't know why, but that's the routine).

I researched and found them to be the best deal in my opinion. Search this site for numerous threads on this topic.
