Updated laser tube cutter for metals and plastics

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.

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.

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.

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

High performance circular saw with modular design

swings up, provides secure protection during the sawing process.

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 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.
