WARNING
Risk of injury from falling of the unit during transport and
assembly!
The use of a crane is necessary for assembling the lathe chuck.
This can be fastened on the eye bolt provided (see Fig. "Assembly
of the chuck" - C). The eye bolt is in all deliveries from chuck size
250 and up included.
Before commissioning the lathe chuck, the eye-bolt has to be
removed.
•
Push the chuck onto the intermediate flange. During this, it
must be ensured that the through-holes for attaching the chuck
coincide with the threaded holes of the flange (see Fig.
"Assembly of the chuck" - D).
•
Next, turn in the fastening screws and tighten them slightly.
Check the chuck for radial and axial run-out (see figure
"Assembly of the chuck" - E) and align with slight blows with a
hammer on the outer diameter if necessary. Next, screw the
chuck tightly onto the chuck flange by means of the fastening
screws using a torque wrench. During this, pay attention to the
specified maximum tightening torques
. Next,
check the radial and axial run-out again as described in figure
(see figure "Assembly of the chuck" - E).
Mounting the chuck by means of a direct mount
When mounting the chuck by means of a direct mount with a
through screw connection, the flange is first attached to the chuck
and subsequently mounted on the spindle.
•
Before mounting the chuck flange on the cylindrical recess of
the chuck, dirt and swarf must be removed from the centring
mount and contact surface of the flange.
•
The flange must be slightly tightened on the chuck by means of
the supplied screws and aligned towards the chuck body. The
radial and axial run-out must be checked.
•
Next, the screws must be tightened with the specified torque
•
After mounting, it must be ensured that the flange is fitted
tightly on the entire surface. Check radial and axial run-out.
After mounting the flange on the chuck, the chuck must be
mounted on the machine spindle.
