Correcting Runout - practicalmachinist.com

Jun 01, 2004· The runout you measured on your spindle nose is pretty good - most CNCs are within 50 millionths in fact. Can I assume you measured the radial runout, and got about the same? And was this on a taper? It sounds like the adapter is riding high on the spindle nose taper, and not bottoming out correctly on the flat mounting surface of the spindle.
