By turning the handwheel
to the right
, move the saddle forward so that the dies come into
contact with the tube end.
Note: A plate on the frame gives a reminder that the saddle moves in the opposite direction
to the direction of rotation of the wheel: the saddle moves to the left (i.e. towards the front
chuck) when you turn the wheel to the right, and vice versa.
!
Turn the wheel slowly to the right applying pressure to enable the die to cut into the tube
end.
When the die has cut 3 or 4 threads, release the wheel and let the saddle move by itself. (You
should not accompany the movement of the saddle as this risks making the thread
inaccurate).
When the preset length of the thread is reached, the dies will retract automatically. (The
operator has to manually open the 1/4” – 3/8” die head).
Stop the motor.
Check that the length of the thread and the outside diameter are sufficient: if a threaded collar
or joint is screwed onto the tube, part of the thread must still be visible. Loosen the chucks
and remove the tube.
Important:
If a thread turns out to be too short, change the length setting and carry out the threading
operation again from the start
and not from the end of the previous thread. (The joint may seize
where the two threads meet).
Producing double threads on short tubes (nipples or reels)
Virax supplies an optional nipple holder which can be used to produce double threads on short
tubes with diameters from 1/2” to 2”:
