SIGMA^® Laser Micromachining System

The SIGMA  Laser Micromachining System is designed to be a flexible laser-integrated system that can process a broad range of laser micromachining applications, such as precision laser ablation and selective ablation, drilling, surface texturing, and marking.  The SIGMA  system can be customized to a large extent, including both its dimensions and its components.  This allows the system to accommodate a wide range of sample part types and sizes, motion stage travel dimensions, laser sources, optical delivery methods, and automation and accessory components, including robotic arms, vibratory feeders, and conveyor systems.  Tooling components are customized to suit almost any application.

Due to the range of different micromachining applications, SIGMA Laser Micromachining Systems can be integrated with a variety of different laser beam delivery heads, ranging from galvanometer 2D scan heads, to fixed-optic focus heads, to multi-axis 3D scan heads.  Femtosecond lasers are typically the lasers of choice, due to their ability to provide the best material removal quality, with minimal-to-no thermal defects, and the highest degree of process stability and precision.  With options in IR, green, and in special cases, UV, wavelengths, femtosecond lasers provide the optimal processing capability for nearly any material, including metals and metal alloys, polymers, ceramics, and glasses.  For processes that benefit from other types of laser sources, the SIGMA Laser Micromachining System can also be configured with a range of fiber, DPSS nanosecond green or UV, CO₂, and picosecond lasers, selected specifically for your application.

The SIGMA Laser Micromachining System is constructed with a rigid steel frame and a granite processing platform mounted to pneumatic isolators to provide excellent vibration dampening for the processing area.  This allows the system to maintain extremely high precision and tight dimensional tolerances for critical processes.  Customizable machine interfaces allow for comprehensive and intuitive system control tailored to your specific process.  For enhanced automation capabilities, AMADA WELD TECH offers automated tube loaders, robotic arms for loading and unloading, vibratory feeders, conveyor systems, and machine vision systems for precision part positioning and feature measurements.  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.
