The Sigma Laser Tube Cutter gas assist fine fiber laser cutting system is ideal for precision cutting of stainless steels, cobalt-chrome steel alloys, and Nitinol. The Sigma fiber Laser Tube Cutter features high speed direct drive stages that maximize throughput. Multi axis options allow users to customize the tube cutter according to the cutting application for both on and off axis cut geometries. A user friendly interface with intuitive icons and customizable options provides easy navigation and programming for either program editing or execution.

The system utilizes a "gas assist" fiber laser cutting technology, also known as “fusion cutting" which is achieved by delivering laser energy to the cut zone assisted by a coaxial gas flow of either oxygen (O2), air, or an inert gas, depending on the materials and laser cut requirements.

This fine laser cutting method can be used for both on and off-axis cutting.  For further information, as well as a comparison with other popular cutting technologies see our Precision Laser Cutting Options paper.

Miyachi Unitek's proprietary position-based laser firing control algorithm enables precise pulse overlap to be maintained during multiple linear and rotary axes of coordinated motion. The laser source can be selected based on specific application and material requirements.
