INFORMATION
If shaped bars (hexagonal, square bars etc.) are to be machined, make sure that
the guide diameter is larger than the diameter circumscribed on the profile, in
order to prevent bar scraping against the sprocket edges.
INFORMATION:
In standard working mode parameter 18 "Guide working mode (0-1)" (see the
"Keyboard Instruction Manual") must be set to mode 0; fork D can be positioned
in any of the slots.
INFORMATION:
When working in "staggered channel" mode, only 3 settings shown in the table
are selectable notwithstanding the 4 available guide channels for the smallest
channel "d" cannot be staggered to a smaller channel.
5.3.3 Working mode with standard and staggered sprockets
Standard working mode
The two pairs of sprockets have the same rotation and do not
move while the bar pusher is moving.
Ideal staggered channels mode
The selected channel is immediately inferior to the diameter of
the bar pusher ; the bar pusher opens the passage while
moving forward by causing the sprockets to rotate and be set
to the next guide channel the diameter of which is larger than
the selected channel.
The bar diameter larger (Picture 051) or even slightly larger
(Fig.041) than the diameter of the selected channel. .
