Abstract: A touching detection device (1) includes: a probe (10) having a touched part (11) with a touch surface (11a, 11b) to be touched by an object to be detected, a support part (13) supporting the touched part (11), and a sensed part (19); a sensor (S) sensing the sensed part (19); and a body (2) holding the probe (10) and the sensor (S). The support part (13) is held by the body (2) to be swingable in a direction in which the object to be detected touches the touch surface (11a, 11b) of the touched part (11). The sensed part (19) is displaced in accordance with the amount of swing of the support part (13). The sensor (S) senses the sensed part (19) and outputs a detection signal when the sensed part (19) is displaced by a preset displacement amount. The support part (13) supports the touched part (11) via an angle adjustment mechanism (15) configured to be able to adjust the angle of the touch surface (11a, 11b) in the swinging direction of the support part (13).

Abstract: A chip discharge device of a machine tool includes a coolant tank storing coolant which is supplied to and dropped from a machining point, and a chip conveyor discharging chips which are generated at and dropped from the machining point, to an outside of the machine tool. A bottom wall of the coolant tank is inclined in a chip discharge side by mounting the coolant tank to the bed.

Abstract: A chip conveyor includes a pair of endless chains arranged in parallel, a drive mechanism turning the endless chains, a cover body having a chip receiving port and a chip discharge port at a beginning and an end of a forward path of the endless chains, respectively, scrapers connected to the endless chains therebetween, and a chip guide plate disposed along the endless chains to be in sliding contact with the scrapers. The chip guide plate is composed of a forward path corresponding part extending from the receiving port to the discharge port and a return path corresponding part bent toward a return path at the receiving port and extended along the return path. The scrapers are in sliding contact with both the return path corresponding part and a surface of the cover body facing the return path corresponding part when in sliding contact with the return path corresponding part.

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.
