High precision, optimum visibility,
and certified robustness
THE advantages of the new generation
of SERVOLASERS from LAP include
extreme robustness and optimum
visibility. The latest version of the
SERVOLASER tireXpert also features
an Ethernet/IP interface to make
connecting to the PLC even more
convenient. Manufacturers also benefit
from the low Ethernet/IP error rate. All
of this makes LAP very useful in laser-
assisted production.
A unique feature of the tireXpert series
is its long rails. Providing a projection
accuracy of up to ±0.5mm, the laser can
be delivered with up to 2,600mm of travel
range. ‘Shorter rails’, with a travel range
of 400mm and above, even provide a
± 0.2mm accuracy.
Another highlight is the travel
speed. The laser modules on the new
SERVOLASER tireXpert move at up to
1,000mm per second.
Unlike
products
from
other
manufacturers, the robustness of the
closed housing on the SERVOLASER
is certified to protection class IP54
(dust and splash-proof). This serves to
protect the optics and mechanics, whilst
ensuring the long service life of the
SERVOLASER.
Every SERVOLASER is put through
a 48-hour test prior to delivery. During
the test, the parallelism and straightness
of the laser lines are controlled
continuously. This is important, because
they are used to control the position of
the individual rubber plies during tyre
building.

Automatic bending cells for
automotive industry
IN the automotive supply industry, the
production of hollow profiles for body
and chassis construction, exhaust gas
technology and other fields of application
benefit from automatic bending cells,
which can simplify the manufacturing
process, offer occupational safety,
withstand non-stop operation, and
increase productivity.
Stricter
threshold
values
for

emissions, efficiency in fuel
consumption, and demands on safety
and comfort force manufacturers and
suppliers to build more components and
to produce them smaller, lighter and
more robust. The use of hollow profiles
plays an important role.
Pipes and tube profiles have to
provide complex geometries and smaller
bending radii.
New high-strength and lightweight
materials as well as reduced wall
thicknesses make new demands on the
machining of hollow profiles.
Tailor-made tube bending cells
permit automatic production of tube
and profiled semi-finished products –
from tube separation and weld seam
positioning via bending process to
integrated quality control, reshaping
or separation systems and unmanned
further transport of the semi-finished
products. They can offer advantages in
the rational series production of injection
pipes, coolant and axle tubes, tie rods,
and several body, exhaust gas system
and chassis components.
The centrepiece of an automatic
bending cell is usually a mandrel
bending machine. In contrast to warm
bending, the cold bending process of
this machine ensures fast and energy
efficient machining processes and
hardly changes the microstructure of
the material. The use
of a bending mandrel
permits the reliable
production of very small
radii, even in the case
of thin-walled tubes.
Schwarze-Robitec
offers various mandrel
bending machine series
for rational mass production. They are
freely programmable CNC controlled
plants that can be integrated into existing
production processes. The machines of
the CNC MR series, for example, have
been optimised for the production of
tubes with different radii or bend-in-bend
geometries. Fitted with stacked bending
tools, they ensure minimal set-up times.
“For every plant we offer a modular
configurable accessory programme
which we adapt flexibly to the specific
project demands and user needs,” said
Schwarze-Robitec managing director
Bert Zorn. “In such a way we develop an
ideal production solution together with
the customer.”
Schwarze-Robitec integrates ma-
chines into existing manufacturing
cells, but can also supply completely
harmonised fully automatic tube bending
machines, depending on demand and
specification profile. The company also
integrates measuring systems for quality
control, upon request.
