Faced with tight production schedules to meet customer demand, new product introductions and an
ongoing continuous improvement programme that sees NC programs updated regularly, Trumpf‘s machine
tool manufacturing facility in Austria relies on VERICUT NC simulation software to provide production
process security
Trumpf Maschinen Austria GmbH &
Co KG is one of 40 subsidiaries and
branches of the German Trumpf
Group that plays a key role in the group’s
global presence. As the group’s expert in
press brake and bending technology, the
TruBend press brakes and the TruBend
Cell 5000 and TruBend Cell 7000
automation solutions, the ToolMaster and
laser-hardened press brakes are all
produced in Pasching, Upper Austria.
In the nancial year ending 2019,
660 employees working at the
36,000 m2 facility generated sales of
around €327 million.
Due to high customer demand in
recent years, production at Trumpf in
Pasching had reached its physical limits.
The order-related production of the
precision-welded machine base is kept
within an extremely tight timeframe, with
a buffer of just two days’ production.
Absolute process reliability is therefore
imperative. In the area of mechanical
production, a continuous CAM process
chain, including tool measurement and
real-time simulation with VERICUT,
ensures production process quality.
The broad portfolio of Trumpf bending
technology includes machines for die and
swivel bending, as well as large-format
bending machines and fully automated
solutions. “With die bending, or folding,
the sheet metal is bent by a controlled
downward movement of the press beam.
Here, the at sheet material is pressed by
an upper tool into a V-shaped lower tool
(die) and formed in a straight line. The
back gauges ensure that the workpiece is
positioned precisely,” explains Bernhard
Zipko, Head of Production at this key
Trumpf business unit.
First and foremost, the mechanical
engineering of the machines must be
precise to ensure the subsequent
accuracy of the bending process. This is
achieved in Pasching through a high level
of vertical integration. “We operate two
modern large-scale machining centres
speci cally for the machining of large
parts such as the machine frame or press
beams, made of ST52 non-alloyed steel
that is ideally suited to welded
structures,” continues Bernhard Zipko.
The frames and beams can be up to
3 m high, 4.5 m long and individually
weighing up to 15 tons each, with
manufacturing tolerances in the
hundredths of a millimetre range,
as Bernhard Zipko emphasises:
“We produce 176 different models and
variants over three shifts using these two
machining centres on a just-in-time basis.
This means that the cycle times must be
low, but the accuracies must be very
high. Even for the longest frames we only
tolerate errors of 0.02 mm.”
CONSTANT FURTHER DEVELOPMENT
In Pasching, process improvements are
the order of the day in all areas,
including, of course, mechanical
production: “Our goal is to increase
productivity by around 6% per year.
We achieve this through the use of the
most modern tools to increase the cutting
data and stability, a constant reduction in
non-productive times, constructive
improvements and optimised
programming of the components,”
explains Andreas Mayrhofer, CNC
Application Engineer.

simulate the original NC code after the
post-processor run. This ensures the
highest level of process reliability when
machining all of the company’s parts.
