ABSTRACT:
In a turret type of machine tool having a turret head which can be rotated for indexing to selectively index an arbitrary one of tool mounting members provided in a plurality of circumferential portions into a machining position which coincides with a predetermined radial direction, the construction of the turret head is simplified to reduce the cost and increase the reliability. A first supporting body is provided which is connected to a moving mechanism which advances or recedes the turret head along an axis of machining coinciding with the axial line of the tool mounting member at the machining position. A second supporting body which is movable along the axis of machining is supported on the first supporting body, and the turret head is rotatably supported on the second supporting body so as to be rotated for indexing. A spindle head is fixed to the first supporting body such that a spindle to be supported on the spindle head coincides with the axis of machining. At least a front end of the spindle head is contained in a space inside the turret head. A tool holder to be held by the tool mounting member in the machining position is engaged with, or detached from, the spindle by the movement of the second supporting body relative to the first supporting body.
