Fitting the precision boring tool
Depending on the required diameter, the
precision boring tool
serrated tool bodies or serrated slides. For
this purpose, use the associated clamping
;
elements (page 19). Please note: the long
side of the clamping bolt
mounted turned away from the cutting
edge, with the flat part pointing in the
direction of the screwhead

Fitting the insert holder
( /
The slider or
tool is provided with serra tions, which
provide a perfect fit for the insert holder
Reverse machining can be
carried out by turning the
insert holder through 180°
(Note: counter-clockwise
rotation!).
Setting the machining diameter
An adjusting device or gauge is needed to
set the machining diameter. Carry out a
rough preset with a cap screw
loosely screwed in by sliding the precision
boring tool onto the serrated part of the
serrated tool body (KZK) or the Alu-Line
serrated slide (KZS) with the aid of a
threaded pin, if available.

1. Slacken the cap screw

to the diameter. A clockwise rotation
produces an increase in diameter.
- Traverse measurement:
1.5 mm (.063") (radial)
- 1 rotation of the scale:
0.2 mm in Ø (.01" in Ø)
- One division on the scale:
0.01 mm in Ø (.0005" in Ø)

.
2.1 Increasing the diameter:
Reset the scale to the value required
(clockwise rotation).
2.2 Reducing the diameter:
Check the value set on the tool (fig.
a, example: scale reading 5). Turn
the scale back by half a rotation,
counter-clockwise rotation (fig. b).
Set new value, clockwise rotation
(fig. c, example: scale reading 2)
