Single head sawing machine 450 mm with electropneumatic inclination positioning. The machine is composed of two main cylinder blocks: a normalized electrowelded steel base and smelting head units. This solution results to be of fundamental relevance to reply to the stresses that arise during the use. The head movement organs are placed in the rear part of the sawing machine. This allowed to obtain some holes on the working table that always allow the scraps drop during the cutting. The machine meets the CE requirements.
