This Cantilever Cutting Machine using the well proven YAG crystal laser optical system technology. Its laser power is 500W maximum. All the optical system is located in the cantilever and water cooled. The structure is well rigid; the steel is treated by an anti-corrosion layer of primer,and then painted. The fume aspiration system mounted directly avoiding any air pollution and there are two drawers to facilitate the removal of the processed parts.
