Abstract
A press is described using piezoelectric actuators to achieve both the hold down of the work piece during the processing operation as well as powering the die used in deforming the work piece. The sub-assembly containing the piezoelectric element is structured to allow convenient removal from the main body of the press thereby facilitating repair operations, as well as coarse and fine adjusting facilities for the position of the piezoelectric element within the actuator assembly.
