HYDROK – Trouble shooting

9.2 Trouble shooting table

Fault

Possible cause

Fault correction

Corrected by

Clamping
device does
not open or the
release stroke
is insufficient.

Fouling of the draw
mechanism

Remove the clamping head
and clean the coupling area
[see section »Disassembling
the clamping head«].

Specialist

Clamping force
is too low

Work piece is under-di-
mensioned

Replace with a suitable
clamping head

Specialist

Insufficient hydraulic
pressure on the clamping
cylinder

Check the machine-side
hydraulic aggregate

Hydraulic
specialist

Compression springs
fatigued [at permanent
tension]

Replace compression springs

Specialist

Dimensional
deviation on
the work piece

Contaminated coupling
area

Clean the coupling area of the
clamping unit [see section
»Cleaning«].

Specialist

Contaminated clamping
taper

Remove the clamping head
and clean the clamping taper
[see section »Cleaning«].

Specialist

Formal defect
on the work
piece

Elastic deformation of
feedstock that is subject
to formal defects. After
machining, the work piece
returns to its original form.

Use feedstock with fewer
formal defects.
Use a clamping head with
several sharp teeth in the
clamping surface.

Specialist

Clamping force is too high Reduce the clamping force to

the valid level for the clamping
device and the workpiece

Specialist

Marks on the
clamping
surface

Point or linear work piece
clamping

Replace with a clamping head
that has a smoother clamping
surface

Specialist

Wrong clamping head
type

Replace the clamping head

Specialist

Excessive dimensional
difference between the
work piece diameter and
the clamping bore

Replace with a clamping head
that has a suitable clamping
bore
