Unique in the world in its category! The cast iron saw unit with a rigid closed loop structure can accommodate a blade of max. 400 mm diameter (for si 400es and Nova si 40) with the scoring blade mounted, ensuring perfect and easy cutting of veneer panels and thick solid wood material. The saw blade uses 100% of the motor power, thanks to the scoring blade with an independent motor as standard. The rotation fulcrums of the saw unit have a 120 mm diameter and stand on steady crescent shaped rests that separate it from the base: a rigid reliable solution.
