A motor-driven machine with integrated suction duct removal of chips drawn or sucked into the machine, comprising: a drive motor; a suction removal fan including a fan wheel connected to and driven by the drive motor, the fan wheel having a plurality of blades; an air guide housing within which the blades rotate, the air guide housing having an inlet and an outlet, and defining a front wall; a suction conduit associated with the inlet of the air guide housing the suction conduit serving to conduct air and chips to the air guide housing; and a disintegrating element situated at the inlet of the air guide housing and in communication with the suction conduit, and extending between the front wall and the blades, the disintegrating element being fixed relative to the air guide housing. The blades of the fan wheel extend axially, face the front wall and define a gap with the disintegrating element. At least one cutting edge-like raised portion is formed on the disintegrating element in the gap, and sucked-in chips are disintegrated by means of the blades and the at least one cutting edge-like raised portion.
