ABSTRACT:
In a turret punch press 1 provided with an upper rotatable turret 5 having a plurality of punches P and a lower rotatable turret 7 having a plurality of dies D, a diameter of the lower turret 7 is determined to be larger than that of the upper turret 5; rotational centers of the upper and lower turrets 5 and 7 are determined to be eccentric from each other; and on a line obtained by connecting the two rotational centers of both the upper and lower turrets when seen on a plane, a position at which the upper and lower turrets 5 and 7 are overlapped upon each other is determined to be a punching position 21 and positions remotely opposite to the punching position 21 and at which the upper and lower turrets 5 and 7 are separated from each other are determined to be indexing positions 61 at which the angular positions of the punch P and the die D can be both indexed. In the turret punch press, it is possible to easily index the angular positions of a plurality of the punches and the dies at need, and further to facilitate the automatization of the turret punch press.
