I use 1/16" grinding discs all the time for such. I think I'd arrange to
clamp the shaft not the motor frame so as to
reduce vibration on the bearings. It it amazing what those discs will do
at reasonable speeds.

Quick and easy way is to use a 1mm cutting disc on a angle grinder.
Slightly harder option is put it in a mill,
clamp the shaft and cut 5mm off
Just don't bang on shaft and you will be sweet.
I would definitely not take them apart that's a headache

I just got a great deal on three 750w brushless servos and drives to
upgrade my cnc mill. They have the same face dimensions, but the shafts
are 5mm longer than the old brush servos. There was no clearance between
the motor shaft and ball screw inside the coupler, so I need shorten the
32mm long 19mm diam shafts by 5mm. Can this be done without damage to the
motor from heat or vibration? I don't want to have to pull the ball screws.
Thanks,
