A machining swarf removing apparatus (7) includes a left and a right machining swarf removing units (25)(26). When removing machining swarf adhered to a recovery box (6), the left machining swarf removing unit (25) is placed in removal starting position. A brush (32) enters an insertion-ready state in which transverse direction thereof is oriented in a second direction D2. The brush (32) is moved to an insertion position for insertion into the recovery box (6), then the brush (32) is rotated to enter a machining swarf removal-ready state in which a longitudinal direction thereof is oriented in the second direction D2. The left machining swarf removing unit (25) is moved to remove the machining swarf adhered to the recovery box (6) by the brush (32), while a left rod vibrating device (43) is driven to vibrate a rod (33), vibrating the brush (32) attached to the rod (33).
