3.2.5 Measuring the clamping force
The existing clamping force is measured with the help
of HSK clamping force measuring equipment by inser-
ting it in the spindle. The HSK clamping forces (draw-in
forces) result from the respective operating forces on
the draw bolt (table 1).
3.3 Dismantling
The locking unit is dismantled in the release position in
the following order:
• The HSK clamping set is dismantled
• The clamping sleeve is released with a special key
(refer to table 3 for Röhm ID no)
• The clamping sleeve is removed together with collet
and draw bar
• The draw bolt is screwed from the draw bolt extensi-
on (sleeve socket wrench)
Dismantling can only take place from the front side of
the spindle. The clamping and release unit must not be
dismantled. A requirement for dismantling the draw bolt
is the rotation prevention of the draw bolt extension.

4. Operation

Release the function positions; clamping and clam-
ping without a tool can be achieved with different
clamping and release units. Irrespective of the
construction and the type of generated forces (hy-
draulic, pneumatic or electric), the operating elements
must always be brought into the neutral position
before starting the spindle. The respective pistons etc
may not come into contact with the end of the draw
bolt and must maintain a constant safety clearance
during the rotation of spindle.
Once the clamping force has been introduced, the lo-
cking unit transfers the operating force onto the HSK
clamping set and mechanically self-locks this traction.
The operating force must and may not be applied
during rotation of the spindle.
The monitoring of the various function positions duri-
ng standstill and the clamping position during rotation
can be individually triggered with different types of
sensors whereby the specific information in chapter 2
must be observed.

5. Maintenance and servicing

The locking unit is maintenance-free. Lubrication
cycles or the replacement of expendable parts is not
necessary.
Clamping force measurements are recommended
to control functions. After a free stroke (clamping
without tool), HSK clamping force measurements can
be undertaken with standard equipment.
The condition of the locking unit is decisive for its
function, clamping and locking force and its durabi-
14
lity. In order to check the condition of the unit, it must be
tested at regular intervals according to the maintenance
instructions. Irrespective of the clamping frequency, a
clamping force test must be carried out after approxima-
tely 40 operating hours. Special clamping force devices
(draw-in force measuring equipment) should be used if
necessary.
The HSK clamping set should be lubricated if the clam-
ping force significantly deviates from the target value
(refer to the clamping set instruction manual). If these
measures are not successful, the HSK clamping set must
be replaced. The clamping force measurements can also
be supported by stroke measurements.
The locking unit must only be replaced according to the
procedure in 3.3 if the new HSK clamping set does not
lead to optimal results and if exceptional loss of the clam-
ping force occurs.

6. Replacement parts

Defective or worn individual parts are not renewed. In
such cases, the locking unit is fully exchanged.
In order to be able to smoothly process subsequent
orders for replacement parts, it is necessary to state
the 7 digit identification number engraved on the
module and, if available, the fabrication number.
We draw your attention to the fact that exclusively ORI-
GINAL Röhm parts or parts from authorised Röhm GmbH
suppliers must be used. No liability is accepted by Röhm
GmbH for any damages resulting from the use of parts
from other companies.
Furthermore, the warranty does not include:
1. Damages caused by the operator due to failure to fulfil
the written instructions of the seller with reference to
the operation and maintenance of the equipment.
. Natural wear and tear.
3. Damages caused by force majeure.
4. Damages caused by any type of incorrect operation or
caused by improper use or operation of the clamping
facility or parts thereof.
5. Damages caused by third parties.
6. Damages which are caused by the use of the system
or parts thereof under irregular conditions (e.g. mate-
rials, work pieces, tools, cutting data or programs etc),
particularly without consulting the seller or manufac-
turer and receiving written approval.
7. Damages which can be traced back to changes to
environmental conditions.
