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 (see chapter "Torque
per screw"
). 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 centering
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.
•
Afterwards tighten the screws with the stated torque (see
•
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.
•
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).
•
Then screw in the mounting screws and tighten slightly. Then
check the chuck for radial and axial runout (see Fig. "Assembly
of the chuck" - E). Tighten the mounting screws on the chuck
flange with a torque wrench. When doing this, observe the
