clamping accuracy and the associated manufacturing accuracy of
the workpiece.
When replacing always use SCHUNK original spare parts.
•
Make sure that the contact surfaces of the mounting surfaces
are always clean.
•
Conduct regular visual and functional checks of the centering
taper and centering sleeve. If there is visible damage, it may be
necessary to replace the component to ensure the required
centering accuracy.
Function Test
The functional test should confirm the proper functioning of the
quick-change pallet systems and the pressure display.
Proper functioning is deemed, if
•
the clamping slide moves smoothly at minimum system
pressure (5 bar).
•
the clamping system shows no signs of leaking.
•
the (safety) indicator pin of the pressure display visualizes the
corresponding operating mode and remains in the respective
position.
Leak test
As part of a leak test, the air and plug-in connections and the
pressure display for turbo monitoring should be tested for leaks.
The following components are required for the leak test:
pressure gauge, supply line with coupling nipple.
Performing the leak test:
1 Connect the components to the air connection in the following
order:
–
pressure gauge, supply line with coupling nipple.
2 Pressurize the clamping system with compressed air.
3 Check the clamping system for tightness in both switch
positions for module control.
4 Check the tightness of the integrated pressure display. The
indicator pin should change to the corresponding operating
mode.
To determine the tightness of the clamping system, no clamping
pallet should be fitted.
