SUPER HYDROBAR HS
3.2.1. End of bar position
The end-of-bar signal is given when the piston (B) enters into contact with the stop ring (C). This moves
up against the pusher disk (D) and releases the microswitch (F). In normal mode, the microswitch is held
down by the spring (G).
The length of the off-cut will depend on the length of the pusher (see point 3.1.2). For the sake of safety,
a maximum distance of 150mm between the exit of the tube and entry of the headstock must not be
exceeded.
NB:
The total travel of the pusher disk (D) and the stop pin (C) is 2
mm. The screw (H) therefore has to be adjusted in such a way
that when the pusher disk (D) is in the rear (or working) position,
the microswitch (F) is ON.
At the end of the bar, the pusher disk (D) is pushed 1.5 mm
forwards. At that point, the microswitch (F) should be OFF.
As total disk travel is 2 mm, there is still a 0.5 mm mechanical
travel in reserve.
Should there be no end-of-bar signal, check that there are no
shavings between the mobile parts of the end-of-bar device
(pusher disk, stop pin, etc.)
End-of-bar monitor
Tube in reloading position
A1 function selector in AUT position
Turn on the lathe in automatic cycle
Allow the piston to move up against the end stop
When the collet next opens, the lathe and the bar-feeder hydraulic pump should come on.
