Circuit for Controlling Stepper Motor on Power Feed

Hi, I am hoping someone can point me in the right direction. I need
a circuit that will generate variable pulse rates to control a power
feed that is driven by a stepper motor.
My turret mill is a Cincinatti Toolmaster which has a fancy DC disc
motor power feed system. Great until one motor burnt out and they
want over 1000 GB Pounds for another! Anyway it is 30 year old
technology so I am updating with the largest stepper motor and drive
from www.arceurotrade.com.
In order to make the thing useful I need a circuit that will
generate the pulses to control the driver. Obviously for power feed
I need to run the motor at variable speeds depending on the job in
hand. This could be via a potentiometer control or even
keypad/switch entry.
The other feature I would like is a fast traverse option to run the
motor at top speed. However, I do not know what 'top speed' is for
this type of motor. The original motor went up to 3000rpm but I
don't think I will get that from a stepper (will I ?).
Any info or sources to consider would be very gratefully received.
