Fine tuning of height

Optionally, the 60 kN KHKP press is equipped with a fine-tuning device for the
press ram (not available for 20 kN KHKP). With this device, the press ram can be
adjusted continuously with an accuracy of 0.05 mm. The maximum adjustment
travel is 12 mm.
Open the door (Fig. 1, Pos. 4) at
the guide unit (Fig. 1, Pos. 3).
Unlock the two hexagon screws
from the countering (Fig. 3, Pos. 1),
but do ot turn out completely.
Now the fine-adjustment device
(Fig. 3, Pos. 2) can be turned
continuously by help of the included
lever up to max. 12 mm adjustment
travel. With the shorter, bent side of
the lever (ø 8 mm) the adjustment
travel can be tested. With the
turned-off side (ø 4 mm), the fine-
adjustment device can be adjusted
(Offset ø 4 mm not shown in Fig.
3). One scale line determines 0.05
mm of adjustment travel.
After the adjustment process the two hexagon screws must be countered.
Close the door again and keep the key in a safe place.
DANGER OF CRUSHING!
The front door must remain closed during all press operations!
