Updated laser tube cutter for metals and plastics

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

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

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.

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
