ABSTRACT:
An electropressing apparatus includes an electric motor driven through a motor driver circuit to operate a pressing ram through a rotational mechanism constructed to move the pressing ram in a vertical direction relative the workpiece. Various detecting and control arrangements are used to detect, memorize, set and change the following: an initial position of the pressing ram; an upper limit stop position of the pressing ram with respect to the workpiece; a lower limit stop position of the pressing ram immediately above the workpiece; a position at which the pressing ram starts to apply a pressure to the workpiece; and a terminal position at which the pressing ram stops to apply pressure to the workpiece.
