Maintenance and care
The item numbers specified for the corresponding individual
components relate to chapter drawings.
Please observe the following instructions in order to keep the
clamping system operating smoothly:
•
Upgrade the base jaws and the chuck piston at least every
three months or more often if necessary (see chapter
, Disassembling and assembling the clamping
force block). Clean housing, base jaws and chuck piston and
reassemble everything.
IMPORTANT!
Please regularly check the clamping device for tightness by
applying a clamping force tester over a longer period of time (>10
min.). The clamping force should not drop during this period.
Please adjust the inspection interval to the operating conditions of
the clamping device, however, we do recommend conducting a
check every 5,000 clamping cycles at the latest.
Disassembling and assembling the clamping force block
When replacing wearing parts (e.g. seals - for seal kit lists see
) adhere to the following order:
NOTE:
The base jaws (2), chuck piston (3) and housing (1) are made to go
together. These parts cannot be replaced individually. To replace
these parts, ship the entire clamping force block to SCHUNK along
with a repair order.
1 Apply 6 bar of air pressure to the clamping system until the
jaws are in the OPEN position.
2 Remove the covering strip (item 8) and the guide strips (item
6).
3 Remove the cylindrical screw (item 69) from the chuck piston.
4 Remove the pressure line.
5 Loosen the screws (items 82, 84) and disassemble the clamping
system from the mounting flange (item 5). Air may escape at
this point.
6 To remove the chuck piston (item 3), screw in the center bore.
7 Pull the base jaws (item 2) out of the housing (item 1).
8 Before pulling off the mounting flange (item 5), all the screws
first need to be removed.
