13.2 Fault table
Fault
Possible cause
Remedial action
Remedied by
Incorrect axial
strokes in the
clamping device
Dirt in the parts in
the power flow
Remove and clean the clamping
elements, and remove, dismantle
and clean the clamping device if
necessary
Skilled specia-
list
Defective drawtube
adapter
Discussion with the manufacturer Manufacturer
Incorrect drawtube
position
Check drawtube position and align
with the clamping device
Skilled specia-
list
Clamping element
cannot be
swapped in or out
Defective axial
strokes in the
clamping device
See fault »Defective axial strokes
in the clamping device«
Clamping force is
too weak
Workpiece outside
the clamping width
diameter
Use a suitable clamping element
Skilled specia-
list
Axial actuating
force on drawtube
too weak
Check machine setting and cor-
rect if necessary
Incorrect lubrica-
tion condition
Check lubrication of the clamping
device and correct if necessary
Clamping force is
too high
Axial actuating
force on drawtube
too high
Check machine setting and cor-
rect if necessary
Skilled specia-
list
Geometry devia-
tion on the work-
piece
Concentricity error
on the clamping
device
Check axial run-out of the clamp-
ing device and correct if neces-
sary
Skilled specia-
list
Face run-out error
of the clamping de-
vice
Check face run-out of the clamp-
ing device and clean the mating
surfaces if necessary
Clamping elements
installed incorrectly
Check the gap dimension
and correct if necessary
Dirty locating area
on the clamping el-
ement
Remove the clamping elements;
clean the coupling area and the
clamping element
Geometry error on
the workpiece due
to incorrect type of
clamping element
Use a suitable clamping element
Elastic distortion
Reduce the clamping force to the
level applicable for the clamping
device and the workpiece
