CNC hydraulic test

Hello Friends,
For years I dreamed of converting the hydraulic control of
my copy lathe into CNC.
Right now I have 2 electronically driven proportional valves
sitting on my table together with the driver boards.
The client permits me to make a test for my project before I shall
install them in his machine.
The input is -10V...0V...+10VDC but I have no computer with interface
cards.
Has somebody an idea how I could make me a simple test set-up to find
out
if these proportional valves would do an acceptable job in an CNC
application?

In THOSE days when I studied it was said it would go OK to make a CNC
machine with hydraulic pistons. Now everybody goes with ball screws and
server or stepper motors. Might be I am stubborn but at least I want
want to have made
a test before I go to ball screws.

Good luck to everybody and enjoy northern summer we have the rain again
in Costa Rica.
