Machining swarf removing apparatus

A machining swarf removing apparatus configured to remove machining swarf by a brush, the machining swarf being generated when a workpiece is machined and being adhered to an inner wall of a recovery box having an opening on an upper surface thereof and extending in a first direction, the machining swarf removing apparatus comprising:

• a moving unit configured to move the brush in the first direction;
• a lifting and lowering unit configured to lift and lower the brush between a storage position where the brush is stored in the recovery box and a retracted position where the brush is retracted above the recovery box;
• a rotating unit configured to rotate the brush about an axial direction of the brush;
• and
• a control unit configured to control driving of the moving unit, the lifting and lowering unit, and the rotating unit, wherein
• the brush is formed such that a length of one side of a plane orthogonal to a lifting and lowering direction is less than a length of another side orthogonal to the one side;
• the length of the one side is less than an opening width of the recovery box in the first direction and in a second direction orthogonal to the lifting and lowering direction;
• and the length of the other side is greater than the opening width of the recovery box in the second direction, and
• the control unit drives the lifting and lowering unit and the rotating unit such that when the brush removes machining swarf, the brush is moved from the retracted position to the storage position in a reference state in which the one side of the brush is oriented in the second direction, and then the brush enters a removal-ready state in which the other side of the brush is oriented in the second direction;
• and the control unit drives the moving unit such that in the removal-ready state, the brush in the storage position is moved in the first direction.
