Abstract
To provide a machine tool in which supporting stiffness of a tool post is increased, thereby enabling improvement in machining accuracy. When seen in a Z-axis direction, a tool post 5 includes: a supporting member 30 having a pair of left and right leg parts 30a, 30a and an upper beam part 30b coupling at least upper ends of the both leg parts 30a with each other; and a turret 31 to whose outer circumferential portion a plurality of tools are attached. The supporting member 30 is supported to be movable in a Z-axis direction between a first and a second spindle headstock 3, 4, and the turret 31 is supported to be movable in an X-axis direction by turret guide rails 33, 33 which are disposed on front faces of the left and right leg parts 30a, 30a.
Claims9
A machine tool comprising:
- a bed;
- a first spindle headstock having a spindle rotation axis and disposed on said bed;
- a moving table disposed to be coaxial with said first spindle headstock and to be movable in the axis (Z-axis) direction;
- and
- a tool post disposed between said first spindle headstock and said moving table,
- wherein said tool post includes:
- a supporting member having a pair of left and right leg parts positioned on the left and right when seen in the axis direction and a beam part integrally coupling at least upper ends of the both leg parts with each other;
- and
- a turret to whose outer circumferential portion a plurality of tools are attached and which is supported by the supporting member, and
- wherein the supporting member is supported on said bed to be movable in the axis direction, and the turret is supported to be movable in an up/down (X-axis) direction by turret guide rails disposed on front faces of the left and right leg parts.
