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 the flexible platform with up to 4 axes of coordinated motion allows for both on-axis and off-axis feature cutting.  The system control software interface and hardware layout provide easy operator use for day-in-day-out production, including a single screen user interface, multi-level password protection, excellent workspace access, quick-open sliding door, internal process area lighting, part capture and unload options, and easy-to-access maintenance points.

The rigid steel frame and granite processing platform mounted to pneumatic isolators provide excellent vibration dampening for the processing area.  Vibration-producing components, like chillers and water pumps, are mounted on an isolated internal platform, standing free of the machine frame.  For enhanced automation capabilities, AMADA WELD TECH offers automated tube loaders, robotic arms for loading and unloading, and machine vision systems for precision part positioning and feature measurements.
