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 andTheta
‘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.
