I'm going to make a milling spindle for my lathe and would like to use angular contact bearings in the rear, and a needle roller bearing at the tooling end - inspired by the Deckel vertical spindle. I'd like the needle rollers to ride on the spindle.. I'm pretty set on this layout for milling.
I'd like to make it from EN19T or EN24T and wondered if either of these would be reasonably hard wearing (as a bearing inner race surface) if lapped then burnished where the needle rollers ride?
The milling spindle would be used only occasionally, driven by 1/3hp motor, ISO20 taper.
Thank you
