Is a reduction drive necessary for servo motors?

Hi,
I'm looking at upgrading a CNC lathe that currently has 210 oz/in steppers
to servo motors.
The servo motors are rated at just over 300 oz/in.
The current stepper set-up is direct coupled using zero backlash flexible
couplers. The ball screws have a lead of 4mm/turn.
As the servos appear to be more powerful than the steppers, I feel I should
be able to do a direct replacement, but have not used servos before.
Do I need to use any gear reduction, or can I direct couple the servos via
the flexible coupling as is done with the existing steppers.
Any help or comments appreciated.
Thanks,
Peter Homann
