Fastening and connection
Flatness
If several linked clamping modules are mounted, make sure that
the flatness and height deviation of the locating surfaces from
module to module (based on a 200 mm gauge for bore holes) is
≤ 0.03 mm. The gauge deviation may not exceed ± 0.015 mm.
Agreement
Due to redundancy, the clamping pins with positioning accuracy in
one direction (PNG.PB.B40) should be used for clamping systems that
are more than 160 mm apart or that do not show a positioning
tolerance of ± 0.01 mm. For the clamping areas that are not intended
for alignment of the device or pallet, clamping pins with centering
clearance (PNG.HB.C40) can be used (also refer to chapter "Clamping
pins"
(

4.5, Page 30) ).
Air bleed screw for the piston chamber
When connecting the quick-change pallet systems, it must be
taken into consideration that it is only possible to completely
ventilate the piston chamber via the air connections during the
locking process. The relevant valves or shut-off valves should
therefore be equipped with load relief.
This also applies to the turbo connection.
If the turbo connection is
not used, the relevant side of the piston must have a way of being
ventilated. This is optimally done via the turbo connection itself.
Only with model size PNG.138: alternatively, a ventilation option can
be created by removing the set-screw M5 x 4 in the module cover.
