  • Patent number: 9339907
    Abstract: To provide a chip disposal device of a machine tool which surely separates and collects a cutting fluid adhering to a chip lump, thereby capable of reducing an amount of the cutting fluid discharged to the outside of the machine. The chip disposal device includes a liquid separating part 65 which separates and collects a cutting fluid adhering to chips, the liquid separating part 65 has a mounting part 66 which is provided continuously from an inclined discharge surface 20a and is inclined so as to get lower as it goes more apart outward from the inclined discharge surface 20a, and to which a first chip lump a1 conveyed by a first scraping plate 36a is transferred. Then, the first chip lump a1 on the mounting part 66 stays on the mounting part 66 until dropping by being pushed by a second chip lump a2 conveyed by a second scraping plate 36b following the first scraping plate 36a.
