2-18 CHAPTER 2: DESCRIPTION
SUPER HYDROBAR HS
Operating pressure
The operating pressure must be set according to the diameter of the guide tube.
Altering the pressure (17) and changing of diameter of the working tube will cause the thrust force to vary.
The operating pressure can be adjusted between 0.8 and 6 bar according to the diameters of the bar to
be worked.
Turning the pressure regulator to the right causes the pressure to increase. This can be seen on the
pressure gauge
If the speed regulator is completely closed, there will no longer be any operating
pressure.
Procedure:

Tube in reloading position

Pusher blocked so that the piston is at least 200 mm short of the end-stop.

A1 selector in AUT position

Speed regulator fully open

Turn on the lathe and the HYDROBAR

Find the desired setting by means of the pressure regulator.
Vitesse d’avance
The feed speed must be sufficient to be able to push the bar while following the positioning movement of
the turret (without damaging it).
The feed speed can be adjusted by means of the flow regulator (18).
Procedure :

Tube in reloading position

Pusher blocked so that the piston is about 200 mm ahead of the end-of-bar stop.

Fully open the speed regulator by turning to the left

Place A1 selector in AUT position

Turn on the lathe and the HYDROBAR
Progressively close the speed regulator until the pressure begins to drop. Reopen the speed regulator
and find the balance point. This is the position in which the feed speed will be at its lowest possible. Now,
to increase it, turn the speed regulator to the left.
