Disassembling of KSZ collet chuck
By removing the mounting bolts (11) the chuck flange (04)
and the base body (07) can be separated. The mounting
bolts (12) remain tightened. In case these bolts are opened
they have to be remounted and thightened with
a torque of 10 Nm (at KSZ-AZ only).
Mounting of the chuck flange (04)
Check the radial and axial accuracy of the machine spindle.
These values should not exceed 5 µm to allow accurate
machining with the collet chuck.
Clean the mounting faces of the machine spindle (01) and
the chuck before assembling. Put the chuck flange (04)
onto the machine spindle (01), orientate and tighten the
mounting bolts (10) according to the specification of the
machine manufacturer.

ASSEMBLY
Reduce the actuating force for the actuating cylinder to the
lowest value possible. Bring the draw tube (02) to its complete
forward (right) end position. Mount the adapter (03)
(optional: has to be machined according to the machine
specification). Screw the draw piston (05) together with the
base body (07) and the workstop base (08) (at KSZ-AZ only)
completely onto the draw tube assembly (02/03). Orientate
the through holes of the bolts (11) of the base body assembly
(05-07) to the tapped holes of the chuck flange (04).
Pull the draw tube at lowest force possible backward (left
direction) and assemble the base body assembly into the
chuck flange (04). Tighten the mounting bolts (11).
Check radial and face runout
Put a dial indicator onto the face of the base body (07) and
check the face runout. To check the radial concentricity put
the dial indicator onto the Id taper. Within the clearance of
the parts the radial runout of the base body can be fine
adjusted. In case the runout cannot be adjusted to less
than 10 µm the chuck has to be disassembled once more
and checked for contamination or damage. Repeat the
assembly process until you reach a runout of less than 10
µm.
