The LWS is SISMA's marking and engraving system for large workpieces. The portal opens on three sides for access to the work area, the worktable lowers or comes out entirely to take bulky and heavy parts, and the coaxial vision system puts the camera on the laser's own optical path for precise, repeatable centering. Beyond marking, it is built for long, deep engraving work.
Specifications for the SISMA LWS-A are listed below as published on sisma.com. SISMA publishes metric figures; the imperial values shown are unit conversions. SISMA S.p.A. is headquartered in Piovene Rocchette, Italy; SISMA laser systems are sold and supported in Southern California by MASCO.
