HEMA Global - The Group is expanding
its production and sales rooms
at the Qingdao location in the
People's Republic of China
Following successful growth in recent
years our Qingdao location had to
expand its production capacities and
services rooms.
German Industry Park, Qingdao
Within just twelve months the HEMA
partner in China, Dr Zhengkang Zhao,
had new buildings erected that need
not shy away from international
comparison.
Steffen Walter, Dr. Zengkang Zhao
Affiliated with the German Industry
Park the company now presents its
production and customer advice divisions
distributed over a surface of
15,000 square metres on four floors.
Here HEMA Zhao is a key pillar and
utilises over 30% of the new area for
catering to the Asian market with even
greater efficiency.
Today many of our customers see the
ideal complement in the coordinated
collaboration between the onsite HEMA
partner and their Asian subsidiaries.
We shall be pleased to support your
efforts in this growth region, which will
be gaining even greater significance in
future.
Electric brake - presentation at EMO
in Milan
HEMA clamping and braking systems
are designed for precision applications
with strokes considerably less than one
millimetre.
However there are many fields that
cannot reliably fulfil these precision
requirements for the guides and contact
surfaces.
Our latest offer has been designed for
just these fields, and we would like to

Electromagnetic disk brake SSB-1000
present to you our SSB-1000 type in a
little more detail as a universal operating/retaining/emergency
brake for
general machine building.
The SSB-1000 is an extremely compact
operating/retaining/emergency brake
with very low energy consumption. Its
floating bearing compensates for minor
axial asymmetries in the brake disc.
Electromagnetic disk brake SSB-1000
The floating bearing for the whole brake
compensates for minor runout errors in
the brake disc and presents a full
contact surface in conjunction with the
parallel transfer of forces to the brake
blocks. The linings therefore do not
need to be ground in.
The brake is available for three disc
thicknesses (20, 25, 30 mm), in two
flange designs, and for two braking
torque ranges.
Potential applications are e.g. in production
lines with FTS interlinking to multiple
machining centres.
Here the components are conveyed over
rails from machine to machine with a
mean tolerance of 1 to 5 mm. Our brake
engages at the transfer station and is
disengaged everywhere else.
A new, innovative type of magnetic
system reliably prevents overheating
and minimises current consumption
(rated power 2 kVA in the breakaway
phase; only 10 VA in the retaining
phase).
The system is designed for IP 65 classification
and can be operated with 230 V
or 400 V.
It applies a nominal retaining force of
10 kN or braking torques up to 6.5 kNm,
depending on the brake disc diameter.
At only 25 kg the component presents
an excellent power to mass ratio. We
can also provide an optional condition
monitor with up to two sensors, an electric
wear limit indicator, and special
designs with sintered linings.
The product can also be used in cranes,
as a chassis brake e.g. in conveyor
systems and mining plant, and in
environments with high temperatures.
NEW - LinClamp can now clamp and
brake in bends as well
In a number of machines traverses take
place not only along straight lines, but
also over gently curving rails.
LinClamp for linear curved guides
Roof cover
LinClamp S, size 100 (new)
Accordingly the market offers roller
guides and linear curved guides.
These elements facilitate high precision
guiding that cannot be obtained with
the conventional combinations of rotary
and linear traverses.
The LinClamp S Series provides the
ideal clamping or braking element for
these applications. Its adaptable clamping
jaw geometry provides a reliable,
fully functional solution for practical
applications.
The HEMA complete roof cover
system allows degrees of freedom on
oversized portal machining centre
Portal milling machines are masters of
versatility. Owing to the gantry design
the moved masses are very small, so
above all large workpieces can be
machined efficiently.
Five side, five axis machining can generate
even complex shapes out of the
material in a short time.

EMO Milan Hall 3, Stand G05 +++ HEMA at EMO Milan Hall 3, Stand G05 +++
The structure minimises vibrations for
high dimensional accuracy, surface
quality, and maximised cutting efficiency.
When designing and adapting each
working chamber in the portal milling
machine there are virtually no limits to
the imagination.
HEMA cover systems installed at
various positions along the x, y, or z axis
or as a complete roof cover allow
various concepts for the clamping table,
integrated partitions, a tandem or duo
design, and various pallet changers.
CoverShutter
Our solutions with integrated rail guides
and pneumatic closing elements enhance
the workpiece loading flexibility
and at the same time provide reliable
machining protection for the work
chamber and the operator's work room.
VISIPORT - projectile proof screw
unions - IWF tested solution now
available
Modern machining centres should be
allrounders. However with this combination
of milling and turning also
manufacturers assigned traditionally to
the pure milling sectors have to adapt
their safety concepts to the turning
machine standard DIN EN 12415.
These machining centres must therefore
be inevitably fitted with glass / polycarbonate
safety windows with verified
retention properties in the corresponding
safety classes, in most cases
B2/B3 or C2/C3.
An additional problem here affects how
the inspection windows are integrated.
HLVB HEMA Linear vertical brake
VISIPORT can be attached with an
adhesive and so presents a possible
solution.
Nevertheless some customers still want
to use their spanners. When the
VISIPORT is screwed through the
glass/PC composite a projectile impacting
the window will loosen the
screws, and there is an incalculable risk
for the operator.
VISIPORT - integrated mounting plate
On the strength of projectile tests
conducted at the Berlin IWF Institute for
all safety classes from A1 to C3 for
inspection windows HEMA has verified
the safety of the HEMA VISIPORT screw
union system.
Customers can now utilise this solution
with an untroubled conscience.
Edition 2009
HLVB HEMA linear vertical brake
for the purely mechanical retention
of loads
HEMA sees itself as a partner for
customised solutions.
A major German machine tool builder
approached us with the assignment to
fit an additional locking system to the
machine housing's sliding door that
opened upwards.
HLVB layout drawing
The vertical, hand operated sliding door
needs a counterbalance.
As a result it can be opened and closed
with the minimum of effort and remains
at any position without falling closed.

+++ HEMA at EMO Milan Hall 3, Stand G05 +++ HEMA at EMO Milan Hall 3 +++
What happens when the connection to
the counterbalance fails?
The sliding door must then be retained
with an additional system if there is to
be no danger to the operator. However
the clamping force should take effect
only when the counterbalance fails, i.e.
in »normal mode« this force must be
balanced out with some kind of system.
This balancing out is ideally the force
exerted by the counterbalance itself,
which is made possible with a suitable
release mechanism.
The HEMA HLVB design provides
particular advantages. The release
mechanism is activated by the counterbalance.
In other words the clamping
element is integrated directly in the flux
of forces, and as soon as this is disrupted
at any point the element is activated
immediately. Owing to the element's
optimal installed position the braked
mass provides an additional boost to the
retaining force.
In this project the braking distance was
verified to be less than 5 mm on the test
rig. There has been some thought about
an expansion with a pneumatic or
electromagnetic release.
DiskClamp for hydraulic braking in
excess of 12,000 Nm
Our new and most powerful DiskClamp
to date does not of course represent the
series standard. However the team of
developers headed by Edmund Likus
has delivered yet another milestone in
the form of the DSC 670.
DiskClamp DSC 670, inner diameter 670 mm
At a swivel table manufactured by an
Italian series machine producer the
DSC 670 operates at 50 bar to exert a
braking torque of 12,000 Nm over thirty
six pistons on its disc.
DiskClamp DSC 670
The internal diameter is 670 mm. In
collaboration with the customer the
system was developed ready for use in
the record time of three months. Our
next DiskClamp project will deal with
the subject of emergency braking on
high speed spindles.
We shall be pleased to support you in
your requests and actual project ideas.
PClamp E now at an even lower
price
This entry level product for low cost bar
and cylinder clamping is now available
at an even lower price! Thanks to optimised
components we can now offer a
15% or 25% discount on this product.
The compact E model can do almost
everything the N types can.
PClamp E
The compact version for lower retaining
forces, the PClamp E is characterised by
a smaller installation height and is
therefore ideal for applications in
constricted spaces or operating areas
requiring low retaining forces.
Initiators cannot be used here. Although
the clamping unit's exterior differs from
the N, X, and ISO versions, the operating
principle is identical.

VECTOR C² OUTSIDE - optimally
closing lamellas, also in corners
EMO news - Japan's number one
machine tool maker puts its trust in its
latest HSC machining centre after
exhaustive endurance tests on the
HEMA cover variant VECTOR C²
Outside.
The VECTOR C² features as a chip protector
two overlapping edged plates
secured to each fold.
This corner lamella solution on three
sides is highly aesthetic and reliable.
The stable design, also travelling at
speeds in excess of 100 m/min, shows in
this example the structural flexibility at
the inside angles, outside angles, and in
combination with several coupled
angles.
Detail of SAMURAI Vector
The special HEMA design of the two
lamellas in the corner provides excellent
sealing and stripping properties.
One feature that particularly convinced
HEMA customers was the lamellas'
contact pressure.
Endurance tests verified the reliability
of the VECTOR C² under the most
gruelling conditions, and new projects
can be tested under field conditions
before kickoff.
