A press machine including a bottom dead center position correction control section, the bottom dead center position correction control section (51, 53) is adapted to perform position correction control that corrects an actual bottom dead center position of a slide to a target bottom dead center position while controlling rotation of an adjustment motor by utilizing target bottom dead center position data and bottom dead center position data detected during a press operation, each press cycle of the press machine corresponding to a single stroke of the slide, the press machine comprising: a speed state determination section (51, 53), characterized in that the speed state determination section is adapted to determine whether an actual press speed in strokes per minute is in a changing state in which an absolute value of a change rate of the actual press speed is more equal to or greater than that of a predetermined change rate or a stable state in which the absolute value of the change rate of the actual press speed is smaller than that of the predetermined change rate; and the press machine further comprises a control cycle count setting section adapted to set a control multi-cycle count; and a mode selection control section (51, 53) adapted to select a single-cycle control mode when the speed state determination section has determined that the actual press speed is in the changing state, and adapted to select a set multi-cycle control mode when the speed state determination section has determined that the actual press speed is in the stable state, wherein the bottom dead center position correction control section (51, 53) performs the position correction control corresponding to each press cycle when the single-cycle control mode has been selected, and performs the position correction control corresponding to each control multi-cycle count set by the control cycle count setting section when the set multi-cycle control mode has been selected by the mode selection control section. a speed state determination section (51, 53), the speed state determination section is adapted to determine whether an actual press speed in strokes per minute is in a changing state in which an absolute value of a change rate of the actual press speed is more equal to or greater than that of a predetermined change rate or a stable state in which the absolute value of the change rate of the actual press speed is smaller than that of the predetermined change rate; and the press machine further comprises a control cycle count setting section adapted to set a control multi-cycle count; and a mode selection control section (51, 53) adapted to select a single-cycle control mode when the speed state determination section has determined that the actual press speed is in the changing state, and adapted to select a set multi-cycle control mode when the speed state determination section has determined that the actual press speed is in the stable state, wherein the bottom dead center position correction control section (51, 53) performs the position correction control corresponding to each press cycle when the single-cycle control mode has been selected, and performs the position correction control corresponding to each control multi-cycle count set by the control cycle count setting section when the set multi-cycle control mode has been selected by the mode selection control section.
