Abstract:
Disclosed herein are an electric press and a method for calibrating the electric press, which can implement a rapid calibration operation. An electric press (10) includes a ram location information storage unit (63) and a load control unit (64). The ram location information storage unit (63) stores ram location information, corresponding to actual load values and representing locations to which a ram is moved, in advance. The load control unit (64) applies an actual load, corresponding to at least one location which belongs to the locations represented by the ram location information and to which the ram is moved, to a compression target by moving the ram to the location. Accordingly, the load value output by the detection unit is calibrated based on the actual load value applied to the compression target.
