SIGMA® Laser Stent and Tube Cutting System

The SIGMA Laser Stent and Tube Cutting System is designed for precision micro-cutting of tubes.  High speed linear motors and the latest generation digital controller minimize tool path cycle time, options for fiber lasers or femtosecond lasers enable a fast and stable laser cutting process, and an AMADA WELD TECH-designed operator-oriented machine interface maximizes user ease and efficiency.  AMADA WELD TECH engineers provide system installation at your facility, along with a fully developed laser process and operational training as part of the system delivery.

The SIGMA Laser Stent and Tube Cutting System can be integrated with either a fiber laser or a femtosecond laser to ensure optimal results for a wide variety of stent and tube materials and thicknesses.  Complete tooling offerings enable laser processing of tube diameters from 0.2 mm – 30 mm (0.008 in – 1.180 in), and th...
