An automated air-burst control device is provided for use with a machining tool to clear away fragments of a work piece being machined. The air-burst control device includes an inlet pneumatically communicating with a source of compressed air. A control valve pneumatically communicates with the inlet, and is movable between open flow and closed flow conditions. The control valve is normally disposed in the closed flow condition for blocking air flow from the inlet through the control valve. An actuator is operatively connected to the control valve, and responsive to a triggering event for moving the control valve into its open flow condition to release air flow from the inlet through the control valve. An air flow outlet line pneumatically communicates with the control valve, and has a free end thereof directed towards the work piece being machined. Upon occurrence of the triggering event, the actuator moves the control valve into its open flow condition to direct a burst of air flow from the inlet through the outlet line to the work piece being machined, thereby clearing away fragments of the work piece from the work piece and the machining tool.
