Abstract: A rotary tool-equipped tool rest is provided, including a movable member made to move frontwardly when a turret is clamped with respect to a non-swiveling housing after swiveling and indexing. Then, a phase determining pin provided in the turret is made to project and engage with the non-swiveling housing. Further, a coupling mechanism to clamp the turret with respect to the non-swiveling housing has three coupling members.

Abstract: There is provided an NC processing machine in which a cleaning operation is carried out automatically, instead of a processing operation. A turret having plural tool mounting surfaces at its outer peripheral surface is supported on a tool post which is movable in the directions of a Z axis and an X axis, such that the turret is rotatable about a T axis. A gripper shaft extending along an M axis parallel to the T axis and is spaced radially from the T axis is rotatably supported on one of the tool mounting surfaces of the turret. A movable gripper capable of detachably gripping a chip cleaning member is mounted to one end of the gripper shaft. A stationary gripper capable of detachably gripping the chip cleaning member is placed such that it can transfer and receive the chip cleaning member to and from the movable gripper within the range of movement caused by composite operations of the movement of the tool post in the directions of the Z axis and the X axis and the rotation of the turret about the T axis.

Abstract: In a rotary tool-equipped tool rest 1, a movable member 27 is made to move frontwardly when a turret 1 is clamped with respect to a non-swiveling housing 2 after swiveling and indexing. Then, a phase determining pin 8 provided in the turret 1 is made to project and engaged with the non-swiveling housing 2. Further, a coupling mechanism to clamp the turret 1 with respect to the non-swiveling housing 2 has three-pieces coupling including a first coupling member 26, a second coupling member 28 and a third coupling member 29.
