Claim 3:
4. The cutting machine according to claim 3, wherein each of said units comprises a body with a first side parallel to the inner side of the plate and a second side orthogonal and underlying the first side, in which the first side slides along a respective guide, the second side is orthogonal to the inner side of the plate and defines a bracket above the blade; and each of the secondary carriages has a first arm parallel to the bracket of the respective primary carriage, to which it is constrained by a corresponding slide guide, and a second arm which is orthogonal to the first arm and, at a free end, supports a shaft of a respective grinding wheel, the second arm passing through an opening formed in the bracket, so that the grinding wheel and the respective shaft are below the bracket and the said second arm is free to move in the opening in the secondary direction, on the first arm of each secondary carriage being connected a connecting rod which, in turn, is connected with a corresponding electric motor, each motor being supported by a surface that each said body exhibits at a predetermined distance from a side parallel to the plate, each connecting rod being connected to the first arm by a pin perpendicular to both the connecting rod and the first arm.
