ABSTRACT:
Disclosed is a turret punch press in which tap holder assemblies TA are incorporated into the press body through tool lifters. Each of the tap holder assemblies TA is composed of a tap holding mechanism, a tap feeding mechanism and a tabular workpiece clamping mechanism formed on the same axis. At the same time, transmission mechanisms DA for selectively transmitting the torque from the press body to the tap holding mechanisms are incorporated into the press body. With a punch press having this construction, tapping can be performed on the same axis as punching.
