AMADA – Laser Cutting and Micromachining
Laser cutting and laser micromachining are non-contact processes which utilize a laser for micro drilling, micro milling, micromachining, micro patterning, micro scribing and ablation for industrial applications. The cut and feature edges are of high quality with little no burring, low surface roughness and dimensional accuracy.
The laser micro cutting process works by directing the laser beam through a co-axial gas nozzle to the workpiece. The laser melts a thin filament of material according to power and part conduction, the pressure of the coaxial assist gas then removes this molten filament through the underside of the cut. This process is repeated as the laser moves across the workpiece. According to cut conditions the periodic removal of material can sometimes be seen as “striation” lines running from the top to the bottom of the cut edge. This is a single pass processing technique that can create single sided features and asymmetrical features with very small internal radii.
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.
