Machine for cutting panels

The invention relates to a machine (1) for cutting a plate (P)， comprising a work surface (3) on which a cutting line is formed， a saw unit (4)， having a circular knife (41) which is arranged to cut from the Exit the work surface along the cutting line， the circular knife (41) being designed to assume a reference position in which it is arranged perpendicular to the work surface (3) to assume a first angular cutting position， in which it is inclined on a first side of the circular knife (41) at a variable angle to the working surface (3)， and to assume a second angular cutting position in which it is on a second side of the circular knife (41) which is opposite the first side is inclined at a variable angle to the work surface (3)， a protective unit (5)， comprising a protective hood (51) to protect the circular knife (41) of the sawing unit (4)， the protective hood (51) being dimensioned so that it has a volume to contain only the volume that the circular knife (41) defines as it rotates from the reference position to either the first or second bevel cut position. The protective assembly can be brought into a first and a second protective configuration perpendicular to the cutting line by drive means (6) and the drive means are arranged between the work surface (3) and the protective assembly (5).
