Updated laser tube cutter
for metals and plastics
Amada Miyachi America Inc, a
manufacturer of laser welding, marking,
cutting and micro machining equipment
and systems, has introduced its updated
Sigma Laser Tube Cutter, which can be
used with both microsecond fibre and
femtosecond disk lasers.
The new cutting system provides edge
quality for both metals and plastics,
making it suitable for medical device
applications, including a wide range of
tubes and stents.
With three and four axes motion
options, and the ability to cut tubes with
diameters from 0.2 to 25mm, the Sigma
is suitable for both wet and dry cutting.
It features an automated tube loader
option and a 22" graphic user interface
on a swing arm.
The Sigma Laser Tube Cutter allows
users to maximise throughput with high
speed direct drive integrated X and
Theta ‘lathe’ axes stages.
Featuring two, three and
four axes options, the tube
cutter can be configured to
the specific cutting application
for both on- and off-axis cut
geometries. The lathe stages
are mounted directly to a
granite base, while the vertical
and horizontal stages are
mounted to a granite gantry
secured to the granite base.
Two different laser source options are
available. The microsecond fibre laser
offers excellent beam quality and high
pulse repetition rates for high speed
precision cutting.
The femtosecond disk laser provides
cut quality using cold ablation cutting to
produce edge quality that reduces post-
processing costs.
Small tube diameters cut with the fibre
laser are cooled using a self-contained
water system that features flow and
level sensors to monitor operation. The
lathe stages and all connections are
sealed for use in wet cutting.
Enclosure options include Class 1
systems in both open and closed frame,
and Class 4 systems, customised to
specific integration, access and loading
speed requirements.

High performance circular saw
with modular design
Behringer Eisele’s robust PSU 450 H
is a high performance circular saw in
modular design, for universal use in
workshops and factories. With saw
blade diameters of up to 450mm it is
suitable for a broad range of tasks.
With the PSU 450 H, the basic machine
comprises a robust frame in which the
base plate and turntable including the
sawing assembly are embedded as a
central unit.
The sawing assembly consists of a
powerful motor and hydraulic feed
cylinder, and a worm drive helical
gearbox with rotation compensation.
For the semi-automatic, the swivel
range is very broad.
The operator control panel is covered by
a cowling, and a protective cover, which
swings up, provides secure protection
during the sawing process.
The rapidly adjustable and exchange-
able clamping units are advantageous
under different sawing conditions.
The clamping units are fitted both
horizontally and vertically. An aluminium
clamp block operating as long-stroke
cylinder with 160mm displacement and
clamping force monitor clamps the
materials safely and precisely.
The clamp force can be set
independently in both directions, and is
readable on two manometers. The large
swivel range enables acute angles of
±30° to be sawn.
