Claims

[Scope of Claim for Utility Model Registration] A turret main body that is rotatable around the center line of one rotation and movable between a retracted position and an extended position along the rotation center line. a supported adapter for removably retaining a cutting tool; an axial drive mechanism for moving the adapter between the retracted position and the extended position; and an adapter rotation drive mechanism that rotates the adapter at the protruding position by an angle equal to the angular interval between a plurality of rotational positions, the positioning mechanism having a circular cross-sectional shape. accomplished,
at least one pin fixed to one of the turret main body and the adapter at right angles to the rotation center line of the adapter and with a part of the pin interfering with the other of the turret main body and the adapter; It is formed in a portion of the other of the tool rest main body and the adapter that interferes with a portion of the pin, and engages with a portion of the pin as the adapter moves to the retracted position at each of the plurality of rotational positions. An index tool rest comprising a plurality of positioning recesses.
