Are taper lock pulleys a good choice for ball screws?

Wait there's a big difference between a router and a milling machine so it's not that simple.!

The milling machine is often rotating the ball-screw much slower with a lower pitch ball-screw. A router is using a high pitch and spinning the screw upto twice the speed and often much longer length (heavier) screws so the inertia becomes more of an issue. Also, servo's or steppers change the outcome. I've got a feeling muzzer is using servo's which have much higher torque than steppers.!

The weight of the pulley and the effect of inertia DOES affect the machine negatively in some circumstances ie: 3D where you are accelerating and de-accelerating quickly with lots of direction changes. Rapid positioning like when drilling lots of holes over a large area where you need to accelerate hard and then slow down between holes.!

All these kinds of operations are affected by the diameter and length of the screw which play a big part in the effect inertia has on the system, so any extra weight you add will only affect this negatively. If you plan to operate at high feed rates or do lots of 2.5/3D work then think carefully about any extra weight you add.

If the screws are long and the gantry heavy then 4.5Nm isn't a massive amount of torque if rotating the screws at higher RPM's.!

I've got a 112mm taper lock and it is weighty.
It's for the 1.8kw servo that's going to be for a mill spindle.
Wouldn't fancy that on a ball screw!!!.
Going to have a go at lightening it with pockets (sort of trivial persuit segments) not cutting all the way through.
