Probably holding speeds to 60 IPM or less would be good. Make sure
you lube your screws frequently through the hole in the center of the table.
Be aware that the Bridgeport scheme lets the Y nut and screw survive
on whatever oil drips off the X nut, meaning it gets shortchanged.
You might want to pull the Y screw every few months and wipe
some light grease on it as a backup lube.
