<p>An abrasive cutting machine includes a housing and a cutting arm on which a cutting tool is accommodated on the end side. The cutting tool is driven via a belt by an engine of the abrasive cutting machine, and the housing encompasses a fan chamber for accommodating a fan wheel by which an air flow is provided. A belt chamber for accommodating the belt is embodied in the cutting arm, with improved durability of a belt, in particular the dust exposure of the belt for power transfer from the engine to the cutting tool. Provision is made between the fan chamber and the belt chamber for an air duct, through which at least a part of the air flow, which is created by the fan wheel, reaches from the fan chamber into the belt chamber, so as to apply a sealing air flow to the belt chamber.</p> |
