Spindles - Lingering Questions

Hey Jim @Webb, hey Bob, hey all,

what I wanted to add is that what I was paying attention to when buying are things like runout, and that the bearings meet ABEC 7 / P4S.

Among other things, I relied on that when buying.

This CNC Depot spindle meets the ABEC 7 requirement, that’s fine. And ISO 30 Tool Changer, that’s nice.

Note that Mechatron spindle has at least 3 bearings.

That’s what I relied on too. My Mechatron spindle is manufactured where I live, they have good support and I have a warranty.
