Mounting of the chuck
Mounting the chuck with a reduction or extension flange
If the chuck is screwed on with an intermediate flange, the
following 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.
• 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.
• A chuck flange made by the user himself must be finished
machining on the machine spindle and must be balanced
before the chuck is mounted.
• After mounting, it must be ensured that the flange is fitted
tightly on the entire surface.
• Next, the radial and axial run-out must be checked (see Fig.
"Assembly of the chuck" - B ( 7.2, Page 28)).
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.
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 quick-change or intermediate flange - C). The eye
bolt is in all deliveries from chuck size 260 and up included.
