Tools for maximising capacity
MANY tube and pipe processing
companies exclusively use custom-
made bending machines to achieve
maximum precision and productivity.
However, full machine capacity is often
only possible in combination with a high-
quality tool solution.
Market requirements rise continuously,
whether through global competition,
more complex tube geometries, or more
exotic materials. The requirements
placed on production processes and
production machines also change.
High-quality tool solutions contribute to
faster throughput times, reduced non-
productive times, and improved total
productivity.
“Those making false economies
usually invest double – in the form of time
and money,” commented Hartmut Stöhr,
managing director of pipe and tube
bending machine company Schwarze-
Robitec. Tube bending machines are
high-tech products, which offer constant
high quality only with the corresponding
tool outfit.
Questions regarding the geometry of
the tubes to be processed, their material
and their output quantity determine the
dimensioning of machine and tools. A
lack of know-how can then quickly take
its toll in the form of high reject rates,
lack of quality, and complaints. “Those
who don’t buy the tools from the bending
specialist should check carefully
whether the initially lower investment
costs can actually be maintained across
the complete production cycle,” advises
Mr Stöhr. “I recommend users to play it
safe in this sensitive area and to benefit
from the advice and experience of the
machine manufacturer.”
For this reason, Schwarze-Robitec
does not sell any ready-made tool series
products. Instead, the company offers
a modular-configurable accessories
programme that is adapted flexibly
to the specific project requirements.
This comprises single-stack tools and
multiple-radius bending tools both for
series and high-volume production.
Schwarze-Robitec designs material
equipment especially for the respective
user industries. Specialised know-how
has been available for decades for
the automobile, boiler and power plant
industries, plant and shipbuilding, as
well as the offshore industry. Common
to all material solutions are the use
of high-quality materials and special
hardening processes, which optimise
the precision, wear resistance,
dimensional stability and endurance of
the tools. High repeat accuracy is also
ensured.
