Modular tube ID scarfing systems
MANY modern tube mills need flexible
production for meeting the precise tube
requirements of their customers.
Alpha Metall provides them with a
modular mechanical tube ID scarfing
system that offers competitive technical
solutions for common tube ID 10-100mm.
For tube ID 26-620mm the hydraulic tube
ID scarfing technology that the company
offers is state-of-the-art.
Both technologies have been
approved in the market for more than
30 years. The operation of mechanical
tube ID scarfing systems is intuitive
for the staff and investment costs are
competitive.
The basic mechanical spare parts
are available from Alpha Metall stock
as and when required. Alpha Metall
commissioning includes staff training
and fine adjustment for perfect tube
ID results. Enquiries on non-standard
customised tube ID scarfing systems
are also welcome.

Circular saw solution for tough
everyday industrial application
WITH its heavy-duty PSU 450 series,
Behringer Eisele presents a modular-
design high-performance circular saw
that adapts to the sawing job.
The PSU is available in a semi-
automatic version, the PSU450-H, and
as the fully automatic PSU 450 VE or
PSU450 CNC2. For sawblade diameters
up to 470mm and a wide cutting range
of up to 160mm for round material and
240 x 85 for slabs, the machine provides
the solution to a wide range of different
sawing requirements. The clamping
units, with fast adjustment and quick-
change facility, are beneficial particularly
where different sawing conditions have
to be taken into account.
Also on offer for both the PSU models
is a version for sawing aluminium. A high-
powered drive system of 6.5/8kW and a
speed of 1,250/2,500 rpm respectively
ensure powerful and fast material
machining. The PSU 450 can also be
connected to an extraction system – a
necessary option when working with
aluminium.
Due to its universal applicability, the
wide speed range of 6-48 or 12-96 rpm
makes the PSU series suited to working
with pipes and square hollow profiles.
In addition, in the semi-automatic PSU
450-H the cutting range for square
material can be further extended using
the adjustable transverse material stop
to as much as 400 x 30mm (when
making 90° cuts).
For curved pipes or hydroforming
products, Behringer Eisele offers the
PSU 450 GS. With the aid of a fixture,
this model is capable of trimming curved
pipes. The two-hand control system
provided as standard eliminates the
need for the protective hood that can be
an inconvenience for this type of sawing
assignment.
Both in thesemi- and the fullyautomatic
version, the basic machine comprises a
hard-wearing machine frame in which
the basic and swivel plate with the saw
are embedded as the central unit. The
sawing unit comprises a high-powered
motor and a hydraulic feed cylinder, as
well as a worm-parallel helical gear pair
with rotation compensation.
The swivel range from left to right is
wide, particularly in the semi-automatic
version, at 30°-45°-90° and 45°-30°-0°.
The fully automatic PSU 450 CNC2 is
equipped with a convenient CNC control
system. In addition, a material feed
axis, a swivel axis for mitre cuts and a
waste disposal unit for optimum process
reliability are integrated into the basic
machine.
The new interactive graphic IPC
control system permits programming not
only in the workshop but also in the form
of online data transmission from a PC
office workstation. The various jobs and
their respective terms of reference are
simply and conveniently programmed on
screen. The large swivel range permits
acute angles of as low as ±30° to be
cut. The program-controlled discharge
gripper of the PSU opens up scope
for the free selection of cuts, with the
gripper travelling automatically out of the
potential collision area of the saw.
Material feed is performed by a CNC-
controlled feed gripper mounted on a
durable backlash-free pre-tensioned
linear guide. Material tensioning takes
place vertically by means of a tensioning
cylinder that adjusts automatically to
the profile size, and horizontally by
the tensioning device of the feed and
discharge gripper. All tensioning pressure
levels can be individually adjusted.
Protective machine enclosures are
designed for simple handling and to
offer the operator a comprehensive
view of the functional areas of the saw
during operation. The modular-structure
sawing system, featuring different types
of magazine and sorting systems,
permits individual customer needs to be
addressed.
