| Zusammenfassung: | A press machine uses a crank mechanism which can perform pressing by a pressing force control when a slide exists in a pressing region. When the slide is determined to exist between an initial position and a switching position to the pressing region, the slide is moved down by rotating a motor regularly by a position control system. When the slide is determined to exist in the pressing region, pressing is performed by moving down the slide such that a slide pressing force becomes equal to a set slide pressing force by a pressing force control system. |
