en ENGLISH Set the chamfer height to "zero" and adjust the scale ring (9) (zero position): 2. Look at the edge of the guide rail (14) at a very flat angle (from below). Lift and turn the adjusting ring (7). Adjust the indexable insert (19) so that virtually no material is removed when working at a later stage (only the edge is scratched). (Chamfer height = 0 mm) 3. Insert mains supply plug. Carry out a trial cut, see chapter 8.2. Pull the mains plug out of the socket. 4. Repeat steps 2 and 3 if necessary until the chamfer height is set to "zero". 5.

Set the chamfer height to "zero" and adjust the
scale ring (9) (zero position):
2.
Look at the edge of the guide rail (14) at a very
flat angle (from below).
Lift and turn the adjusting ring (7). Adjust the
indexable insert (19) so that virtually no material
is removed when working at a later stage (only
the edge is scratched). (Chamfer height = 0 mm)
3.
Insert mains supply plug. Carry out a trial cut,
see chapter 8.2. Pull the mains plug out of the
socket.
4.
Repeat steps 2 and 3 if necessary until the
chamfer height is set to "zero".
5.
Loosen the two clamping screws (8) on the scale
ring.
6.
Turn the scale ring (9) so that the scale is set to
"0". See figure:
7.
Tighten the two clamping screws (8).
Determining the setting value:
Note:
always produce large chamfer heights in
several milling operations (at least 3). Hard
materials require more milling operations. This has
the following advantages: a higher indexable insert
service life, work results with a higher surface
quality, more pleasant working conditions.
Do not exceed the "maximum chamfer height
per milling operation" specified below.
KFM 15...(at 45°):
1st milling operation: max. 6 mm
2nd +3rd milling operation: max. 2 mm
KFM 17...:(at 45°)
1st milling operation: max. 9 mm
2nd +3rd milling operation: max. 3 mm
Do not exceed the maximum permitted chamfer
height (h
max
) (see the Technical Specifications
chapter).
It is recommended that very little material is
removed during the last milling operation to ensure
an optimum surface quality.
8.
Select the diagram that applies to your machine
(see back).
9.
Select the line that applies to the set chamfer
angle (see back).
10.
Example
for a chamfer angle of 45° and a
desired chamfer height of 3 mm (see figure
below). Result: setting value = 2.0.
Select the chamfer height that you want to set on
the Y-axis. Draw a horizontal line to the
intersection with the line. Draw a vertical line
from this intersection to the X-axis. Read the
value on the X-axis. You must now set this "X"
value as follows on the machine.
Note:
The diagram is based on sharp-edged
workpieces. For workpieces with rounded
edges, the milling height must be taken into
account during setting.
Setting the chamfer height:
11.Pull the adjusting ring (7) upwards and turn it so
that the "X" value from the diagram is set on the
scale (9). See figure (below): set "X" value = 2.0.
(One revolution corresponds to "X"=3. For large
X values: perform several revolutions. The scale
(6) is used for rough orientation during the
setting process).
12.Carry out a trial cut.
13.Proceed as follows if the chamfer height should
be set very accurately for the last milling
operation:
Carry out a trial cut. Measure the cut chamfer
height and adjust it by one scale mark if
necessary by turning the adjusting ring (7):
clockwise rotation = larger chamfer height.
Anticlockwise rotation = lower chamfer height.
Carry out another trial cut. Repeat this step if
necessary.
