Tailor-made solution for
challenging demands in
steel tube and bar
A GERMAN bar manufacturing compa-
ny that had highly non-standard cutting
and testing requirements for its unique
thread bar products, which are made
out of high-tensile specialist steels, has
been offered an innovative solution by
Bültmann.
Bültmann’s reputation for innovation
and high levels of experience dealing
with similarly challenging specialist
applications made it a logical choice for
the bar manufacturer.
Special bars of 30m length and with a
maximum diameter of 85mm are flexibly
cut into several different lengths by
means of an efficient sawing unit with
tungsten carbide tools.
As a consequence the bars are
distributed in different order-related
transport racks and packed into
transport bundles when
ready. Length positioning
to the nearest millimetre,
as well as the automatic loading and
unloading of the products, is carried out
by two handling units with independent
axis control.
Adequate gripper systems ensure
precisely defined material handling and
high process reliability.
A 100 per cent quality control inspec-
tion of the final thread automatically
takes place before the bars are passed
and discharged into the transport racks
without intervention by the user.
Special testing units are installed
to provide the necessary dimension-
dependent thread testing gauges.
The test procedure is fully torque
controlled. This automated, precision
process ensures that when the end user
receives the product, the thread bar
systems delivered correspond exactly
to their demands for quality and ensure
that the bars can be used for the most
demanding applications.
Bültmann added that it is looking
forward to continuing to take on
challenging projects and maintaining
a close cooperation with its customer,
which has used several specially
designed Bültmann peeling and
straightening lines for many years.
