Fault
Causes and solutions
Dual stroke chuck:
When clamping the workpiece the 3
indicator pins protrude from the
front side more than 0.5 mm;
or the base jaw edge is outside of
the permissible area marked
“Clamping Zone”;
or, if mechanical stroke monitoring
with an inductive proximity switch is
installed, the machine receives the
signal “Clamping not permissible”
The overlap of the clamping stroke in the chuck
piston is insufficient. There is a danger that parts will
be damaged in the force transmission area.
The top jaws must be offset radially outward by one
or more teeth until the indicator pin in the chuck
body is countersunk during O.D. clamping;
or t
he base jaw edge is within the “Clamping Zone”;
or, if stroke monitoring is installed, the machines
receives a release signal.
Pressure monitoring with the
inductive proximity switch sends no
release signal.
Check working pressure.
Clamping cylinder is leaking in the cylinder or valve
area; check working pressure.
Replace defective seal elements. If necessary,
completely dismantle chuck, clean, grease and
replace O-rings and/or profile seals.
Pressure monitoring with the
inductive proximity switch initially
sends a release signal. After a short
time the machine no longer receives
a release signal.
Chuck is leaking in the cylinder or valve area. Check
working pressure.
Replace defective seal elements. If necessary,
completely dismantle chuck, clean, grease and
replace O-rings and/or profile seals.
