  • Composite lathe
    Patent number: 7240412
    Abstract: To provide a composite lathe enabling the overlapping of movement areas without lowering supporting stiffness of a tool post, and thus realizing enhanced machinability. An XY supporting plane A by which a tool post 5 in is supported to be movable in an X-axis direction is set non-parallel to an XZ supporting plane B by which a third spindle 6 is supported to be movable in the X-axis direction, and an axis of the movement in the X-axis direction of the tool post 5 is set apart in a Y-axis direction from an axis of the movement in the X-axis direction of the third spindle 6.
    Type: Grant
    Filed: March 31, 2006
    Date of Patent: July 10, 2007
    Assignee: Mori Seiki Co., Ltd.
    Inventors: Yukinaga Sasazawa, Kazuhiko Matsumoto, Tsutomu Tokuma
  • Composite lathe
    Patent number: 7237310
    Abstract: To provide a composite lathe enabling downsizing of a machine main body and realizing an enlarged machining area. A cutting point “c” of a tool post 5 is positioned vertically under a straight line connecting axes “a” of a first spindle headstock 3 and a second spindle headstock 4, and an X-axis stroke of a cutting point of a third spindle 6 overlaps an X-axis stroke of the tool post 5 by a half or more of the X-axis stroke of the tool post 5.
