Denford Software & Machines

hello,
now i'm doing my thesis(degree) in developing of cnc machine,
and my main reference is from novaturn lathe.
can i know the motor is servo motor or stepper motor. and its specification.
ur help can help me alot.. because i know nothing about this machine.

stepper motors on the x and z axis, dc motor on the spindle.

do u have any specification on the x and z axis stepper motor. i mean the type of the motor is it variable reluctance motor or hybrid? if the motor is variable reluctance is it bipolar or unipolar motor..sry if i made mistake.ty
