    摘要： A spindle head for machine tools includes a housing (16), a spindle (12) having a through-hole (12b) formed therein and a tapered portion (12c) at one end thereof for receiving a tool holder (8), a bearing means (14, 44) for supporting rotatably the spindle (12) in the housing (16), a draw-bar (30) placed in the through-hole (12b) of the spindle (12), a collet (36) connected to the draw-bar at its one end for holding the tool holder (8), and means (20, 28) for moving the spindle (12), the bearing means (14, 44) having a concave portion (14c). The spindle (12) has a convex portion (12a, 42a) corresponding in shape to the concave portion (14c). The concave portion (14c) of the bearing means (14, 44) cooperates with the convex portion (12a, 42a) of the spindle (12) so that the bearing means (14, 44) can support the spindle (12) in both radial and thrust directions.

    摘要： Provided is a machine tool that can suppress an increase in centrifugal force which is generated when turning an end effector, and prevent an increase in route errors of the end effector. This machine tool comprises: a rotary unit that rotates around a first axis; a first arm extending from the rotary unit; a second arm that is connected to the first arm, and supports an end effector; a single power source that is configured to supply power to the rotary unit and the second arm; and a switching mechanism that is configured to switch a destination of power supply from the power source, from one of the rotary unit and the second arm to the other. The second arm is configured to rotate around a second axis intersecting the first axis.

    摘要： The present disclosure discloses a complex machining turning center. In the complex machining turning center according to the present disclosure, a tool post 103 is moved on a bed 101 along an X-axis by a slide rest 104, a tailstock 105 is moved along a Z-axis direction, and a headstock 102 is moved in a C-axis direction, and the complex machining turning center includes: a B-axis swing movement unit 110 which allows the headstock 102 to swing along a B-axis on a plane coordinate formed by the X-axis and the Z-axis; and a Y-axis up/down movement unit 120 which allows the headstock 102 to be moved upward and downward along a Y-axis that crosses the X-axis and the Z-axis.
