Abstract: A composite processing machine with an automatic swiveling composite turret device. Transmitting and releasing of rotational force to a rotating tool is automatically switched between indexing and locked securing. Included is a clutch-action-coupled rotational force transmission/release switching mechanism (10). A common motor (9) is the drive source for a rotation drive mechanism (7) for transmitting rotational force to a rotating tool (5) and a swivel drive mechanism (8) for swiveling a turret (3). Transmission of rotational force of common motor (9) to rotation drive mechanism (7) is released when turret (3) is slid along swivel shaft part (2) to unlock clutch device (4) and enable turret (3) to swivel, and rotational force of common motor (9) is transmitted to rotating tool (5) when turret (3) is slid back to lock and secure clutch device (4) in an indexed position of turret (3).

Abstract: The present invention provides a machine tool provided with a cover body having a simple structure, excellent operability, and low manufacturing cost. A tool post movement region one-side-closing cover part (9) for closing a tool post movement region open part (8) is configured so as to be: capable of expanding and contracting in a horizontal movement direction of a tool post (3); arranged facing the tool post (3); elongated by urging means (10) to press against the tool post (3) in a relatively slidable manner and close the tool post movement region open part (8); expanded and contracted by movement of the tool post (3) to hold the tool post movement region open part (8) in a closed state; and provided unconnected to the tool post (3) so that the tool post (3) is relatively slidable with respect to the tool post movement region one-side-closing cover part (9), and the tool post movement region open part (8) is held in a closed state.

Abstract: A machine tool in which a fluid discharge port (4) for discharging a fluid (F) supplied from a fluid supply unit is provided to a rake surface (3) of a blade tip section (2) provided at a distal end section of the cutting tool (1), which cuts the workpiece (W), and the fluid (F) is discharged from the fluid discharge port (4) toward a rake-surface (2)-facing surface of chips (D) from the workpiece (W) that slide in pressure contact with the rake surface (3), the fluid (F) discharged from the fluid discharge port (4) reducing the force with which the chips (D) that slide in pressure contact with the rake surface (3) make pressure contact with the rake surface (3), and reducing the amount of frictional heat generated by the chips (D) sliding in pressure contact with the rake surface (3).
