It could be used, but I think you could do better. These are low inertia
motors, and are not needed for an XY table application. Also, this is
a 1300 W motor, which seems VERY high for your application. I'm
using a 1/8 Hp (continuous) motor on a Bridgeport!

To properly use this motor, you'd need an appropriate servo amp for it.
The speed would be limited if you used it with a Gecko servo drive.
