In a press device for pressing a slider with a plurality of motors as driving sources, pressing is performed while a slider is kept horizontal even if an eccentric load is applied. In this press device, in the teaching stage, when the eccentric load is to be applied, a degree of shortage of a driving torque in each of the driving sources is determined at each timing when the eccentric load is applied so that a torque addition signal for compensating for the torque shortage is supplied to the respective corresponding driving sources corresponding to the respective timing during the actual machining
