STARK zero point clamping systems

Zero point-based flexibility – due to element or nipple
SPEEDY classic 2 balance – we place emphasis on flexibility
Direct workpiece clamping – a gripping topic for the future.
However this technology has its demands.
STARK Spannsysteme has accepted this challenge and developed a system that has the characteristic of equalising corresponding tolerances.
The SPEEDY balance series has particular advantages: existing threads on the workpiece can be used, a special fit is
not required. Thanks to the integrated equaliser function in the
clamping element of +/– 0.75 mm
the workpiece can be clamped directly using the thread without additional effort.
The retractable nipples are available with different threads.
They can be screwed in either manually or using automation.
The system has zero point accuracy and therefore the workpiece can be used on several machines or even for intermediate measurements.
Safety checks are integrated with a pneumatic clamping check
and release check. The supply lines to the clamping elements
are supplied hydraulically via deep bores. Other versions, e.g.
DHF (third hand function) incl. pneumatic checking are available on request.
The clamping element described in the flyer is based on
SPEEDY classic 2 technology (clamping using spring force
20 kN, hydraulic release). Other elements such as SPEEDY
hydratec (double-action hydraulic) or SPEEDY etec (electrically
powered) are also available.

Flexible height and position clamping element (art. no. 6000 008)
The newly developed, flexible position clamping element from
STARK solves clamping situations where "adaptation to suit the
workpiece" is required.
The "distortion" of workpieces is a sensitive topic during any
mechanical machining process that now also affects zero point
clamping technology. While with pallets, plates and stable
parts, overdetermination (multiple clamping and
support points) can be accepted.
In the case of thin-walled parts and direct workpiece clamping,
the risk of "distortion" is however very high.
Distortion-free clamping is possible using a 3-point support.
But what happens if stability suffers as a result? If further
clamping and support points are necessary?
Workpiece with multiple clamping and support points
It is exactly here that the flexible position clamping element
comes into play – clamping and support in one element.
First the clamping force is applied to all clamping elements with
up to 20 kN. While the 3 support points are fixed
and pulled onto the supports during clamping, additional flexible position clamping elements are also moved into position at
further retaining points and
clamped. The fixing force achieved depends on the hydraulic

Flange retractable nipple with equaliser ±1.5 mm in one axis
The critical contradiction of "stable clamping" and the necessary "movement" is ideally solved with the retractable nipple with equaliser. The retractable nipple with equaliser is used if a large amount of thermal expansion is to be expected. The compensation of
±1.5 mm also contributes to simpler and cost-saving manufacture of the pallets, as larger manufacturing tolerances are possible. In
addition the flange on the retractable nipple can be used as a hardened, wear-free support.

Zero point clamping systems – from simple to complex
SPEEDY easy click - now also with blowing out and system control
Clicks in immediately, also without supply of energy
Clicks – and holds
The new SPEEDY easy click is a mechanical fast closing clamp
that clicks in and stays in place without the supply of energy.
Release is simply by means of an air connection at a pressure
of 3–8 bar or a power socket.
SPEEDY easy click is used for cutting and non-cutting
The mechanical clicking system makes SPEEDY easy click
ideal as a robot gripper in automation engineering. The quick
clamping time (click) enables it to be used as a design element
in production lines. The particularly compact design permits
tight spacing, short retractable nipples 15 mm long ensure
short extraction distances.
Integrated polling options and oil-free operation extend the
range of applications.
The SPEEDY easy click is also available with system control,
polling and blowing out.

Want to machine workpieces on 5 sides and clamp with repetitive accuracy?
Then the modular systems from STARK are just right.
STARK has developed zero

1988 and is considered a pioneer in this field. The retractable nipple is mounted directly
on the clamping device or
directly on the workpiece.

Optical clamping check
Is the zero point clamping
system securely clamped?
In many applications,
e.g. during turning, the
clamping check is a must.
The newly designed optical
clamping check checks the
position of the piston in the
SPEEDY and outputs absolutely reliable information via a
traffic light signal. Straightforward operation and straightforward upgrading are key
advantages of these safety

Booster - change pallets quickly and safely
The booster is used for releasing single-acting clamping systems.
It converts compressed air into hydraulic pressure and is suitable for ranges
from 30 to 80 bar. A major advantage of the new booster is that pressure can be
applied to several SPEEDY classic at the same time.

Coupling quickly and safely – pneumatically, hydraulically
Multimedia coupling (electrical + pneumatic)
The STARK media coupling with the combination of pneumatics and electrics was specially developed for automation.
During this process particular attention was paid to reliability.
The coupling can be used in combination with all STARK zero
point clamping systems. An automatically extending, integrated
clearing nozzle keeps the contacts clean.
A special seal ensures the reliable transfer of all media in harsh
everyday conditions.
n Electrical and pneumatic coupling with clearing device
n Extremely small space envelope
n IP67 (coupled)
n Can be combined with all STARK zero point clamping systems
Example: Gripper for robot with multimedia coupling
Multimedia coupling (hydraulic + pneumatic)
If several lines are to be coupled and uncoupled again at the
same time, this solution represents an enormous simplification.
STARK is also setting new standards in relation to reliability
here! The coupling, which can be configured as required by
the customer (number of lines and nominal sizes), is equipped
with the SPEEDY easy click. This feature makes it possible
to safeguard the connections via the machine controller or
the unit used. Only if the related enable has been provided
n One coupling process for all media by SPEEDY easy click time saving
n A safety function can be integrated in the actuation of the
SPEEDY easy click (enable for coupling by controller, polling
coupling parking station).
n Tidy hose connections - no mix ups
is it possible to remove the manual coupling from the parking station. Coupling is then undertaken by simply pushing
into place – the SPEEDY easy click engages. And only if the
enable to uncouple has been given (e.g. only once all lines
are depressurised) is the SPEEDY easy click supplied with the
release pressure. The actual release process, the uncoupling,
is undertaken conveniently using a button. It could not be more
straightforward and more reliable.

Docking unit with media transfer
Minimise set-up times –
relocate set-up times
Significant cost-savings
in manufacturing are now
increasingly only achievable
by shortening process times
and especially by relocating
set-up times away from the
machine. Productivity can
be significantly increased by
using zero point clamping
systems with the related time
The docking unit supplies
the pallet with oil and air for
clamping, releasing, clearing
or polling. This feature has
several advantages at once:
n All the energy and supply
lines are routed via the
docking unit.
n Saving in expensive
machine pallets
reduces costs, storage
space and weight.
n Automated solutions can
also be realised using a
simple range of machinery.
Pallet store with more than 50 jigs
Effective protection of the clamping point is ensured by the central locking provided by the
clamping elements SPEEDY classic 4. The raised supports and the central locking are cleaned
using the integrated clearing nozzles. As a consequence automated, repetitively accurate
clamping is possible. Thanks to the flexibility due to the usage of the zero point clamping system
and the minimisation of the set-up times, processing times can be significantly reduced and
enormous costs saved. It is only on the usage of these systems that unmanned, fully automated
work shifts become possible.
