ADJUSTMENTS AND SETTING-UP

•
Turn the knob A to lift the lower clamp until the bar
axis is lifted to approx. 2 mm over the bar-pusher axis
C . Turn the screw B to lower the upper clamp until the
bar axis becomes aligned with the bar-pusher C axis
again (the sensor S5 must not be energized).
•
Turn the crank vigorously to obtain bar introduction
into the bar-pusher collet. Make sure that the clamps
do not let go of the bar during this operation. Repeat
this operation two or three times to make sure that
good adjustment has been obtained. Then continue
to turn the crank until sensor
S2 becomes energized.
5.4. CAM BOX - TIMING
If the feeder is equipped with a cam box, each cam should be
timed to its own microswitch. The timing procedure is as follows.
❑
Microswitch function
S90 - Bar feed enabling
It controls the bar feeding motor start/stop. It must be operated at
each collet opening. In addition, it also controls operation of the
bar/headstock synchronizing device.
S91 - Bar change-over enabling
It signals lathe collet opening/closing to the feeder.
It determines the camshaft stop position at bar end.
S92 - Feed stop enabling
Only used in sliding headstock lathes. It disables the feeding thrust
during any operations requiring headstock return with a closed collet.
S99 - Camshaft stop
It determines the camshaft stop position when there is no thread (con-
nected in series with a microswitch or relay located on the lathe).
