NOTICE
Tighten the mounting bolt accroding to the specified
torque
. If tightening torque is insufficient or too
strong, bolts might brake.
Use only attached bolts.
NOTICE
In order to achieve the full stroke of the chuck the draw nut
needs to have sufficient play in the spindle. The ROTA NCKplus
315-A6 will only achieve its full stroke if the draw nut blank is
shortened by 4 mm.
Mounting
Mounting the chuck with a reduction or extension flange
If the chuck is screwed on with an intermediate flange, the follow-
ing points must be observed:
For mounting the chuck on the machine spindle with a short taper
by means of a reduction or extension flange, a corresponding
chuck flange is attached on the spindle nose.
1 Before installing the chuck flange, remove any dirt or swarf
from the machine spindle and from the centring mount and
the contact surface of the flange.
2 A chuck flange made by the user himself must be finished ma-
chining on the machine spindle and must be balanced before
the chuck is mounted.
3 After mounting, it must be ensured that the flange is fitted
tightly on the entire surface.
4 Next, the radial and axial run-out must be checked as in
. During this, proceed as described in figure B
The chuck is mounted after the flange has been aligned. During
this, it must be ensured that any contaminations on the flange and
on the chuck contact surfaces are removed.
