Rotating spindle, with numerous types of vices.

High-precision stepper spindle.

Coaxial Vision System (CVS). The viewpoint of the camera coincides with the optical path of the laser beam and allows the work area to be viewed directly in the programming software, greatly facilitating the construction of the machine program.
Advantages:
– High precision and repeatability of centering;
– Possibility of eliminating jigs or fixtures;
– Possibility of laser rework on the same part to achieve the required depth or finish.

Pattern Matching (PM) is a software feature added to CVS (optional) that enables automatic recognition of workpieces on the table and consequently accurate and repeatable positioning and execution of machining operations (marking, engraving, cutting, etc.).

FILL-IT software for generating filler graphics for aesthetic effects. It is capable of reproducing effects such as perlage, sunburst, côte de genève, brushed, sandblasted and with the possibility of customised effects.

Double red pointer.

Modular and 2D-3D laser engraving and texture “Easy mold” solution is available.

Plate vise.

Fume suction unit.

LWS Brochure

The SISMA LWS is designed for industrial laser marking, deep engraving and permanent part identification on large or heavy metal components. Its flexible workstation design makes it ideal for manufacturers producing machinery, tooling, moulds, fabricated parts and precision-engineered components where accuracy and repeatability are essential.

Suitable for marking serial numbers, Data Matrix and QR codes, product branding, logos, traceability information and deep engraved features, the LWS supports efficient production workflows while maintaining exceptional marking quality. Optional CVS vision technology, Pattern Matching software and rotary axis accessories enable automated positioning and reliable processing of complex or cylindrical components, making the system an excellent solution for both single-piece and batch manufacturing.

You ask, we answer

Yes. Unlike compact desktop laser markers, the SISMA LWS is specifically designed to accommodate large, heavy and complex components. Its spacious three-sided working area and optional removable or lowering worktable make loading oversized parts easier while maintaining precise laser positioning.
The SISMA LWS is used across a range of industries including automotive, aerospace, engineering, toolmaking, medical device manufacturing, electronics and precision metal fabrication. It is particularly suited to manufacturers requiring permanent, high-quality identification and traceability marking on metal components.
The SISMA LWS can be equipped with advanced technologies such as the Coaxial Vision System (CVS), Pattern Matching software and optional motorised X, Y and Z axes. These features improve positioning accuracy, reduce setup time and ensure consistent marking quality, even on complex or irregularly shaped parts.
