Fwiw..
On steppers, the max acceleration with 48V DC, 542 drivers, Nema 23 3Nm steppers, 3:1 via HTD 5/15 mm, about 0.8 secs to max speed.
My table on a moving table VMC is over 200 kg in mass.
It stops in maybe 1- 2 mm from max speed. Using hw pulsing from a good generator, lately pokeys.

On 400W ac servos, Nema 23, 3.9 Nm peak, it stops in about 1 mm or less.

On the lathe, the new saddle assy == 150 kg.
32 / 4 mm ballscrew, 750W cont ac servos, 10 Nm peak.

X starts and stops in much less than 1 mm, if I was to use high acceleration - I don´t.
I use about 20% of max acc. for "normal" use.

Steppers in the past used to do similar, with much lower top speeds, and much less accuracy.

My c axis spindle and z axis (lathe) have about 10 kW of power in terms of inertia (I know its not kW technically).
Ie industrial turning centers (HAAS ST10) of 10 kWh cont. has about the same peak torque (102 Nm at 1200 rpm) as I have (90 Nm) 0-1000 rpm.
Using a 10" 4-jaw chuck.

The steppers at 1:3 ran about 600-700 rpm, 200 rpm+ at screw of 5 mm rise.

The servos run 3000 rpm, but I only use one third or 1000 rpm.
Very fast accelerations are like hitting the screw mount bearings with a big hammer, 10 kg, literally.
It wears the bearings out fast.

My mounts could take 3000 kgf loads, you could stand a truck on them.

Recap:
Lathes and mills typically go to max-speed in about 1 mm - 2 mm of travel.
Steppers are ok for full-out, and servo systems depend on a lot of stuff.

Anecdote:
The ac servos go to 3000 rpm in about 20 ms, 0.02 secs. Both 60V 400W and 220V 750 W servos.
It is likely the lathe servos could do full-peak accelerations, with the saddle, to 3000 rpm, at 0.02 secs or so.

At 10 Nm direct drive peak, the push force is about 650-700 kgf, 7000 N, near 1900 lbs of force.
For 150 kg mass on saddle assy, ==> 4.3 kgf.
43 m s/s acceleration.

At 1000 rpm x 5 mm, = 5 m/min. /60 = .083 m/sec.
8.3 cm/sec.
In 0.02 secs, the travel is 0.166 cm, = 1.6 mm.
