4. Balancing
Any necessary precision balancing can
be carried out on the complete tool with
set screws screwed into extension/
reducing adapters from the outside. This
means that the residual imbalance based
on the complete tool can easily be
achieved for different quality levels Q as
a function of the operating speed.
No additional balancing surfa-
ces or holes must be added
to this boring tool!
Max. permitted residual imbalance of
the machine manufacturer has to be
observed (if necessary complete tools
have to be balanced).
5. Operation
Fixing the insert holders
hight displaced cutting
The two-part and axial height-displaced
front of the tool is provided with serra-
tions to enable the insert holder to be
simply and quickly fitted. Transposition
of the insert holders is not possible,
since the difference in height is in the
tool and not in the insert holder. The
f-dimension of the insert holder is always
the same. The rigid side is for the insert
holder for roughing
5
and the moving
side – the slide – is for the insert holder
for finishing
6
. Refer to the technical
data regarding the tightening torque for
the special screw
7
to secure the insert
holder.
Fixing insert holders with level cut
When machining with
level cut distribu-
tion
, the insert holder must be fitted on
the appropriate side for rough machining
(silver-grey). The roughing end of the
boring tool as well as the roughing insert
holder are marked with a triangle.
Adjusting and clamping
the insert holders
An adjuster device is required to set the
individually adjustable cutting edges.
Setting the insert holder for rough
machining
Set the diameter by adjusting on the
front serrations with the fastening screw
7
only lightly screwed into the slot in
the insert holder. More precise setting
can be carried out with the grub screw
8
in the insert holder, in which the grub
screw presses against fastening screw,
thereby allowing an adjustment of the
diameter into the positive range. For
support against fluctuating cutting for-
ces, this grub screw must always be in
contact with the fastening screw.
Adjusting and clamping
the insert holder for finishing
To clamp the slider
9
and the adjuster
nut, the tool is equipped with a clamping
piece
