Tube and profile processing
NOT all tube work pieces have to be
processed within a tolerance range
of 0.01mm. In addition, the machines
available for processing 6m or 12m tube
lengths in a diameter range up to 140mm
have functions that may not be required
for particular applications. Machine
hourly rates are so high that the treatment
of simple work pieces is too expensive.
For work pieces that only contain
diagonal drillings or threads and have
to be cut in length or mitre, the RBV20
tube processing machine from hebö is
an alternative solution.
Tube processing machines have to
be able to react as fast as possible to
customer demands. A challenge in tube
processing is rapid variant diversity.
As result there is a trend towards
small series or individual production.
Production plants that cope with these
requirements have to be flexibly adjusted
to the changed conditions.
Instead of buying detailed solutions,
there is a trend towards complete
packages, with everything from a
single source – from material feed and
removal of material over processing, to
commissioning, training and after-sales
service.
The module-based RBV20 machine
system from hebö covers easy
applications, eg set-up of one drilling
unit with one feed axis, a control
cabinet and controller with a ready
plug-and-play system, to complex,
fully automatic production plants.
Based on the work piece the complete
process chain is considered and an
optimal solution according to individual
demands is devised.
For reaching a high rate of machinery
uptime, RBV20 controllers are supplied
with a diagnosis system to find the
source of errors quickly. Specialists from
hebö can also provide assistance via the
standard supplied remote maintenance
module. RBV20 can process profiles up
to a perimeter diameter of 140mm. By
the grab-through principle almost any
profile lengths can be worked on. The
high dynamic tube feed drives with a
maximum speed of 1,000mm/s. Round
and square tubes can be processed
from all sides by a 360° profile-rotating
device. Other profiles can be processed
using a special clamping device.
Commercially available tubes
and profiles have several tolerance
deviations. These are dimensional
deviations of cross section profiles, form
errors of cross section, and bending
or torsion deviations over the profile
longitudinal axis. By clamping directly
in the working area and using the grab-
through principle, these deviations are
compensated partly.
Drilling units that are orthogonal to the
tube longitudinal axes can be swivelled
up to 60° to make diagonal drillings.
Drilling, core cutting, flow drilling and
thread forming are standard procedures
for an RBV20.
