Workpiece is out of tolerance
Dirt between segmented clamping
sleeve and mandrel taper. Remove and clean the screw and
segmented clamping sleeve

deformed during the clamping process.
After machining, it should go back to
its original shape
Use material that is less bent out of
shape initially
Marks on the clamping area Point or linear workpiece clamping
The difference between the clamping
diameter and the workpiece bore is too
large. Change to a segmented clamping
sleeve that fits

workpiece
Dirt on the mounting surfaces Clean the soiled surfaces
Workpiece is not clamped
Clamping bolt has not been fully tightened
