General assembly notes

The item numbers specified for the corresponding individual

components relate to chapter drawings.( 11, Page 40)

Assembly, dismantling and modification work on the quick-change
pallet system may only be carried out by specialist personnel.

Request our installation drawings if doing the installation yourself.

Disconnect the power supply lines and ensure that there is no
residual energy in the system before performing assembly,
modification, maintenance, or adjustment work on the
pneumatically actuated quick-change pallet system.

Wear protective equipment (gloves, protective shoes).

Access to the drive piston (pos. 4) on the side must be ensured
during the assembly of the manually actuated quick-change
pallet system, in particular in the event of clamped clamping
pallets. Check whether the drive piston is easy to access in order
to open or close the clamping module prior to the installation.

WARNING

Risk of injury due to dropping the quick-change pallet system
during transport

Transport with care.

CAUTION

Risk of injury due to crushing

Install the quick-change pallet system carefully.
Do not place any limbs into the gaps or between the clamping
station and the machine.

If several linked clamping units are mounted, make sure that the
flatness and height deviation of the locating surface from module
to module (based on a gauge of 200 mm) lies within 0.01 mm. The
interface position deviation must not exceed ± 0.015 mm.

Due to redundancy, the clamping pins with positioning accuracy in
one direction (SPB mini 20) 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 (SPB mini 20) can be used (also refer
to chapter "Clamping pins SPA 20 mini, SPB 20 mini, SPC 20 mini"

( 6.4, Page 23)).

NOTE
When connecting the pneumatically actuated quick-change pallet
system, ensure that it is only possible to completely ventilate the
piston chamber via the air connection on the base side 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, it must be possible to
ventilate the relevant side of the piston. Be sure to take the
ventilation methods into account (see Fig. "Air bleed screw via

turbo connection").

Ventilation via turbo connection

When dismantling the clamping system from the machine table,
the corresponding openings must be secured with set-screws to
prevent ingress of dirt.

If several units are activated via shared hose lines, feed lines with
the following minimum cross-sections must be used.

Fastening and connection NSE mini 90

The NSE mini 90 is fastened in the installation space by 6 M6
screws (see Fig. "Fastening and connections NSE mini 90").

The assembly module is positioned using the centering diameter of
the installation space: Ø 90H6.

The air connection is made the standard way via the coupling bore
on the lower face side of the quick-change pallet module. This
requires that the bottom opening be sealed with an O-ring, which
is inserted into the O-ring seat in the table top.
Machine the axial sealing O-ring seat according to the following
dimensions: Ø 9

+ 0.1

x 1.1

+ 0.05

.

The accessory pack of the NSE mini 90 contains the O-rings Ø 6 x

1.5 (item 14) for sealing the hose-free direct connections on the

base side.

When the turbo connection is used, the spring-actuated locking
procedure is actively supported with air pressure.
If the turbo connection is not used, the relevant side of the piston
must be able to ventilate.

Fastening and connection NSE-M mini 90

The NSE-M mini 90 is fastened in the installation space by 6 M6
screws (see Fig. "Fastening and connections NSE-M mini 90").

The assembly module is positioned using the centering diameter of
the installation space: Ø 90H6.

As standard, the clamping system is driven manually by rotary
movement at the drive piston (item 4), which is on the side in the
base body (item 1).

The clamping system can be operated by means of a hexagonal
screwdriver (angled pin wrench).

No air supply is required for the operation of the clamping system.
The openings on the base side therefore do not have to be sealed.

Fastening and NSE mini 90-V1, NSE-M mini 90-V1 connection

The NSE mini 90-V1 and NSE-M mini 90-V1 clamping modules have
fitting grooves for position orientation of the clamping pallet.

The modules are fixed in the installation space with 6 M6 screws.
One of them is a mounting location fixed with a fitting

6.3.3

Assembly

02.00|NSE mini 90, NSE-M mini 90 |en

23

screw (see fig. "Fastening and connections NSE mini 90-V1, NSE-M
mini 90-V1").

The fitting screw is designed for position orientation and anti-turn
protection of the quick-change pallet module in the installation
space. In the installation space an additional fitting bore is
required for position orientation via the fitting screw.

The Fig. "Fastening and connections NSE mini 90-V1, NSE-M mini
90-V1" below shows how a clamping pallet is connected to the
VERO-S NSE mini 90-V1 quick-change pallet system (NSE-M mini
90-V1). Individual clamping pallets and clamping devices can be
attached to the interface of the VERO-S NSE mini 90-V1.
When producing clamping pallets in-house, pay attention to the
exact positioning clearance of the indexing pin bore to the middle
of the clamping pin. For dimensions, please refer to the
illustration. The indexing pin IXB V1 PAL mini is not included in the
scope of delivery of the quick-change pallet system and must be

ordered separately (see "Accessories" chapter ( 4.1, Page 14)).

SPA 20 mini, SPB 20 mini, SPC 20 mini clamping bolts

NOTICE

Notes on clamping pins and mounting screws

The holding force of the quick-change pallet system is limited
essentially by the tightness of the screw connection which
connects the clamping pin to the pallet or the device. This is why
only screws of strength class 12.9 may be used.
Only original SCHUNK clamping pins may be used.
If the clamping pins are to be used in customer-owned devices,
the customer must provide sufficiently dimensioned threaded
holes or a sufficiently thick mounting material.

The clamping pins can be attached to the device or pallet in two
different ways. The mounting variant on the left in the illustration,
which is screwed from above, is the preferred variant. With this
variant, if there is a module failure then the device or pallet can be
removed after disassembling the clamping pins.

Note about pallet changing

NOTICE

When changing the pallet using lifting equipment or a robot,
ensure that the pallet is lifted exactly parallel to the modules.
The inclination (X) during lifting may not exceed 1.2°.
If the inclination is larger, the clamping pins can jam and the
system components could be damaged or destroyed. In this
case, the system must be inspected and damaged parts must be
replaced immediately.
Only original SCHUNK spare parts may be used!

02.00|NSE mini 90, NSE-M mini 90 |en

Pneumatic circuit diagram

The pneumatic circuit diagram shows the supply lines and the
pneumatic components for actuating the different functions of the
clamping system. When the monitoring function is connected, the
measurable differential pressure should reach at least 1 bar when
one clamping module is shut down so that secure evaluation can
be performed via the air gap sensor. The maximum pressure of the
monitoring function is 2 bar. In order for the monitoring function
to be actuated, a flow control valve with a preset air volume flow
of approx. 15 l/min must be connected upstream in the feed line.

In order to guarantee reliable evaluation, the pressure and air
volume must be held constant. Pressure fluctuations can affect the
settings of the pressure switch and lead to incorrect measurement
results.

6.6

Assembly

02.00|NSE mini 90, NSE-M mini 90 |en

The length and cross-section of the line can affect the switching
time of the control components. It may be necessary to readjust
the control components. Check the control components of the
monitoring functions at regular intervals. If errors occur in the
monitoring control system, you must detect the cause of the error.

direction and release the clamping pin.

3 The pallet can be removed.

The clamping pins are available as separate accessories in three
models (see chapter "Clamping pin SPA 20 mini, SPB 20 mini, SPC
20 mini" Link Spannbolzen). The clamping pins are mounted on
customized pallets or devices.

Locking

1 Depressurize the system.

2 The clamping slides are guided inwards by spring force. When

locking, the pallet is pulled onto the contact surface of the
clamping module and the clamping pin is clamped in the
clamping module in a self-locking and form-fitting manner. It
is therefore not necessary to apply pressure to the clamping
module during machining.

3 When the turbo connection is used, the spring-actuated

locking procedure is actively supported with air pressure. A
turbo impulse is sufficient for a higher pull down force. If the
turbo connection is not used, the relevant side of the piston
must be able to ventilate. The clamping pin is centered at the
taper bore of the clamping module, which is why the angular
alignment of the clamping system can be selected as desired.

Clamping functions with the manually actuated clamping
system

The manually actuated clamping system can be operated by
means of a hexagonal screwdriver (angled pin wrench).

No compressed air is required for the function. This makes the
clamping system extremely flexible and allows it to be used
wherever no pressure medium is available.

Unlocking

1 The manually operated clamping system is unlocked by a

rotary movement on the side drive piston (item 4) with the
required unlocking torque (see chapter "Technical Data"

( 5, Page 15)). Insert the spanner wrench into the hexagon

socket of the actuator spindle and turn counter-clockwise.

2 The clamping slides secured by springs (item 7) move

outwards until the final position of the rotary movement
noticeably engages. If the rotary movement is not carried out
to the end position during opening, the drive piston can turn
back and lock the clamping system again.

3 The clamping pin is released.

The clamping pins are available as separate accessories in
three models (see chapter "Clamping pin SPA 20 mini, SPB 20
mini, SPC 20 mini). The clamping pins are mounted on
customized pallets or devices.

4 The pallet can be removed.

Locking

1 The pallet can be inserted in the clamping system as soon as

the clamping slides are unlocked and the rotary movement on
the drive piston noticeably engages.

2 Insert the pallet in the clamping system.

3 Insert the spanner wrench into the hexagon socket of the

actuator spindle and turn clockwise.

4 The clamping slides are guided mechanically inwards by spring

force. When locking, the pallet is pulled onto the contact
surface of the clamping module and the clamping pin is
clamped in the clamping module in a self-locking and form­fitting manner. The clamping pin is centered at the taper bore
of the clamping module, which is why the angular alignment
of the clamping system can be selected as desired.

Clamping slide position monitoring

The quick-change pallet systems NSE mini 90 (-V1) and NSE-M mini
90 (-V1) have a standard pressure monitoring of the clamping slide
position.

This way, an electronic differential pressure switch can for
instance be used to monitor the dynamic pressure at the clamping
sides of the quick-change pallet system. This means the slide
position can be monitored electronically in order to ensure that
the clamping slides are in an unlocked position as soon as the
pallet can be lifted. A pressure switch signals to the operator or
the machine which position the clamping slides are in. This way,
the clamping system can be protected from any possible damage.

The air connection is performed as standard via the base-side
connection bore of the quick-change system on the cover (item 2).
For information on sealing the air connection, please refer to

chapter "Fastening and attachment" ( 6.3, Page 18).

Pressure build-up in the "OPEN" and/or "CLOSED" mode. One of
the two monitors, or when necessary both monitoring
connections, can be connected and overseen for mutual security.
Control of the clamping slide monitor requires a reduced pressure
supply limited to 2 bar (see "Pneumatic circuit diagram"

( 6.6, Page 26)).

The measurable differential pressure must reach a minimum of

0.5 bar in order for a reliable evaluation to be done via the air

gap sensor. The maximum pressure is 2 bar.

Monitoring requires a pressure gauge, an adjustable throttle and
an air gap sensor.

The control of the module is performed using the hose-free direct
connections.

For this purpose, the provided connections (see illustrations in
chapters "General assembly instructions" and "Fastening and

connection ( 6.3, Page 18)) must be controlled via bore holes on

the base side and the M3 set-screw in the cover (item 2) must be
removed.

The air bleed screw must lead through an open groove in the table
top. This requires that the bottom opening be sealed with an O­ring, which is inserted into the O-ring seat in the table top.

dimensions: Ø 9

90 contains the O-rings Ø 6 x 1.5 (item 14) for sealing the hose­free direct connections on the base side.

Use of the dynamic pressure monitoring function is not mandatory
for the basic operation of the clamping module.

NOTICE

If the pneumatic monitoring function for monitoring the
clamping slide position is not used, it must be ensured that the
quick-change pallet systems can be loaded or unloaded without
being damaged.

• Before loading or unloading the clamping pallet it must be
ensured that all integrated clamping modules are unlocked.

• Before beginning the machining process it must be ensured
that the integrated clamping modules are locked, and that the
clamping pallet is placed flat on the locating surface.

Monitoring of the operating status can be ensured by lifting or
shaking the clamping pallet.

In the case of clamping modules with manual actuation, attention
must be paid to the correct position of the drive piston (stop limit
on the left or right). A marking with the directions of rotation at
the circumference of the clamping system shows the selected
operating state.

Maintenance and care

NSE mini 90 and NSE mini 90-V1

The pneumatically actuated quick-change pallet systems NSE mini
90 and NSE mini 90-V1 are designed for low-maintenance
operation, meaning the clamping modules must only be opened or
disassembled in exceptional circumstances.

CAUTION

Risk of injury and risk of damage to the pneumatic clamping
modules when opening the modules.
If a pneumatic clamping module has to be disassembled, send
the module to SCHUNK for repair.
Drive ring and piston are spring preloaded and must only be
removed and installed using a special installation tool by trained
specialist personnel and in line with the appropriate removal
and installation manual.

NSE-M mini 90 and NSE-M mini 90-V1

The manually actuated quick-change pallet systems NSE-M mini 90
and NSE-M mini 90-V1 are designed for low-maintenance
operation, meaning the clamping modules must only be opened or
disassembled in exceptional circumstances.

If disassembly of the manual quick-change pallet systems is
necessary, observe the following instructions:

1 Clean all the parts thoroughly and check for damage and wear.

Replace any damaged or worn parts. Only use original
SCHUNK spare parts.

2 Grease the sliding surfaces of all movable components with

Renolit HLT 2.

To ensure the quick-change pallet system operates perfectly, the
following instructions must be observed:

Pressure medium: Compressed air, compressed air quality
according to ISO 8573-1:7 4 4

NOTICE

A separate maintenance unit with oiler must be used for the air
supply.

Ambient conditions and operating conditions

• Make sure that the contact surfaces of the interface are always
clean.

• Make absolutely sure that no chips of any kind can enter the
interface and that the interface does not fill with cooling
emulsion, which is particularly possible with vertical positioning
of the clamping pin axis. The best way to ensure both of these
is to use the SDE mini 20 or SDE mini 90 protection covers.
If the interface should fill with cooling emulsion, initiate the
unlocking process and dry out the interface in actuated state.

• Only use high-quality cooling emulsions with anti-corrosive
additives during processing.

• Check the units at regular intervals (at least every two weeks or
after 1000 clamping operations). The system is functioning
correctly if the clamping slides move smoothly at minimum
system pressure (6 bar).

• Carry out regular visual/functional checks. In case of visible
damage or signs of malfunction, shut down the quick-change
pallet system immediately. The system may only be started up
again once the faults have been corrected, for instance by
replacement of a damaged module.
