manuellem Unwuchtausgleich.
Maximum permissible cutting speed:
Vc = 2'000 m/min.
EWB UP (Ultra Precision) class boring
heads are fitted with an innovative, ex-
tremely precise fine adjustment mecha-
nism. This enables fine adjustments of
0.001 mm on Ø (1µm to be made directly
from the gold dial (9) ). Any unbalance is
very easily compensated using an integrat-
ed counterweight, which is adjusted to the
required finished diameter by means of the
additional chrome dial (11). All the heads
contain coolant holes to provide cutting fluid
right up to the insert.
Adjusting the diameter:
- Loosen the clamping screw (2) on the fine
adjustment mechanism (9).
- Turn the gold fine adjustment dial (9)
counter-clockwise until it stops. Do not
force the dial! Then rotate the dial 3 full
turns clockwise to the nearest whole
number (10).

- Loosen the clamping screw (4) for the in-
sert holder (3).
- Coarse adjustment: The end face is fitted
with a cog wheel (7). This is used for
coarse diameter adjustment between the
insert holder (3) and the fine adjustment
cartridge. The scale (8) is useful as a
coarse guide.
- There is a coarse adjustment slot (6) in
the insert holder (3). Set the insert tip (5)
to the required diameter. Do not forget
the allowance for the measuring cut.
E.g.: Required Ø42, Allowance in Ø0.25;
Set Ø: 41.75.
- Tighten the insert holder clamp screw (4).
- When tightening the clamping screw (4),
the fine adjuster may shift slightly, so ro-
tate the fine adjustment dial (9) back one
turn and then forward to the same whole
number on the dial.
- Fine correction of the diameter: Rotate
the fine adjustment scale (9), always in a
positive direction (clockwise), to set the
final diameter. Be aware of the cartridge
travel limits.

counter-clockwise direction to the end stop.
Periodic lubrication: Approximately every 20
