Overview
Built around the size of the part
SISMA LWS is designed for large, heavy or hard-to-transport parts. The work plane can be lowered or removed to suit the size and weight of the piece, and a large portal that opens on three sides gives access to the work area. The Z axis is motorised, and the X and Y axes can be motorised if required.
Three versions are offered. LWS-M has manual X and Y axes and a fixed worktable; LWS-M Plus adds a motorised X axis; LWS-A has three motorised axes, a lowerable or removable worktable and a motorised door. An XXL version has a 1215 x 1050 mm work surface.
The maximum marking size is 280 x 280 mm with a 420 mm focal length. Besides marking bulky parts, including isolated marks in a single area, LWS is suited to long, deep engraving. With a rotating spindle it can machine circular parts up to 150 mm in diameter.
