Chucks in size 265 or above
• Offset the base jaws (item 22) up to the outermost marking of
the chuck face.
• Lift the chuck to in front of the spindle lug using an eye bolt
flush to the center of the spindle.
• Screw the rotating center sleeve (item 14) onto the draw tube
as far as the stop using the supplied assembly tool (item 23).
• Slightly tighten the supplied chuck mounting screws (item 31)
alternately to attach the chuck to the spindle nose.
• Check the chuck for concentricity and axial run-out accuracy
(see Fig. } 5.4 [
/
29] ) and, if necessary, align at the outer
diameter with gentle taps using a hammer.
• Tighten the mounting screws (item 31) with a torque wrench.
Observe the maximum admissible torques } 4 [
/
26] .
• Check the chuck again for concentricity and axial run-out
accuracy (see Fig.
}
5.4 [
/
29] ). The "Concentricity and axial
run-out tolerances" table shows the concentricities and axial
run-out accuracies to be achieved.
• Check the actuating force is functioning and is sufficiently large.
• Move the clamping cylinder to the foremost position. Unlock
the jaw connection with the supplied jaw change key (item 20)
and insert or offset the base jaws into the chuck's jaw guidance
as shown on markings 1, 2 or 3.
• Check that the base jaws can move easily and check the jaw
stroke.
At regular intervals, check that the retainer ring (item 15) is
seated firmly.
The parts are disassembled in the same way but in the reverse
order.
