Chuck Removal
To remove chuck:
1. DISCONNECT MACHINE FROM POWER!
2. Use appropriate lifting, support, or protective
device to protect ways and support chuck
(refer to
Chuck Safety & Support Devices
section for more details).
3. Loosen camlocks by turning key counter-
clockwise until each cam line is aligned with
its corresponding spindle mark, as shown
below.
Cam line and spindle mark aligned
Figure 33. Camlock is fully loosened when the
cam line is aligned with the spindle mark.
Tip: Camlocks can become very tight. A
cheater pipe may be used as a last resort to
add leverage when loosening. After loosen-
ing, you may need to wiggle the chuck key in
the camlock to fully disengage the stud.
4.
Using dead blow hammer or other soft mal-
let, lightly tap around outer circumference of
chuck body to loosen it from spindle.
5.
Remove chuck from spindle, using light rock-
ing motion to carefully slide studs out of cam
holes.
— If chuck does not immediately come off,
rotate it approximately 60° and tap it
again. Make sure all marks on cams and
spindle are properly aligned for removal.
This 3-jaw, scroll-type chuck has an internal scroll-
gear
that moves all jaws in unison when a
djusted
with the chuck key
. This chuck holds
cylindrical
parts on-center with the axis of spindle rotation
and can be
rotated
at high speeds if the workpiece
is properly clamped and balanced.
IMPORTANT: Never mix jaw types or
positions
to accommodate an odd-shaped workpiece.
T
he chuck will spin out of balance and
may throw
the workpiece
! Instead, use an independent jaw
chuck or a faceplate.
