Marchetti's hydraulic tensioners, for marble and granite, ensure uniform tensioning of the blades, increasing their life and efficiency. The uniform tension also speeds up the installation and dismantling of the blades in the blade holder frame. The tensioners can be mounted on any blade holder frame with diamond or non-diamond blades. In recent years Officine Marchetti has developed special cuts for slabs up to 8 mm thick, continuing to improve their equipment always in step with the times.
