General Installation Notes
The clamping pins are available as accessories and are suitable for
transporting the clamping station. The eye bolts can be screwed
into the internal threads of the clamping pins.
The quick-change pallet modules of the clamping station are
unlocked with compressed air to insert the clamping pins.
CAUTION
For transport, the air supply must be disconnected so that the
clamping pins remain locked.
When connecting the quick-change pallet systems, it must be
taken into consideration that it is only possible to completely
ventilate the piston chamber during the locking process. For that
reason, the corresponding valves, sound absorbers or shut-off
valves should be fitted with load relief.
This also applies to the turbo connection. If the turbo connection is
not used, it must be possible to ventilate the relevant side of the
piston.
When disconnecting hose lines, the relevant openings must be
secured with seal plugs to prevent ingress of dirt or cooling
lubricant.
CAUTION
Danger of injury due to sharp edges and rough or slippery
surfaces
•Wear personal protective equipment, particularly protective
gloves.

Aligning the clamping station
The clamping station can be aligned with loose T-nuts along an
aligning groove on the machine table. At least two T-nuts offset
lengthwise are provided and their size is matched to the aligning
groove on the machine table. The T-nuts are not included in the
scope of delivery of the clamping station.
Alignment using T-nuts
Mounting the clamping stations
Flatness and distances
In order to assemble the clamping station, the clamping surface
must have a flatness of ≤ 0.02 mm (based on the entire support
area of the clamping station). The clamping zone must have
sufficient rigidity in order to ensure the relative flatness of the
clamping modules. If several clamping stations are installed that
are linked, it is important to ensure that the flatness and height
deviation of the locating surfaces from module to module (based
on a 50 mm gauge for bore holes) is ≤ 0.02 mm. The gauge
deviation between the separate clamping stations must not
exceed ± 0.015 mm from module to module.

01.00|NSL mikro 50-13 1425873|en
Compliance
For the sake of conformity, clamping pins with positioning
accuracy in one direction (SPB mikro 10) should be used for
clamping modules within a clamping station or multiple interlinked
clamping stations 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 (SPC mikro 10) can be
used.(4.4, Page 25)
Even height of the clamping modules
Even height of the clamping modules within a clamping station is
only ensured when in a clamped state. The clamping station is to
be fastened with the BRR mikro 17 clamp blanks included in the
scope of delivery. The clamping station must be fastened on the
machine table with all clamp blanks provided to ensure safe
mounting. The clamp blanks must be fastened with adequately
dimensioned fastening screws in accordance with DIN EN ISO 4762
of thread size M4 or above. The prescribed arrangement for the
clamp blanks can be found in the following clamping diagram.
CAUTION
The height of the modules will only be even once the clamping
station has been properly mounted on the machine table.
For the arrangement of the BRR mikro 17 clamps see the
"Clamping range" illustration.
