Abstract
An electric discharge machine is provided. The electric discharge machine includes: an axis drive part moving a tool electrode in at least one axial direction; and a sensor unit detecting a linear movement position of the axis drive part in the axial direction. The sensor unit includes a measurement scale having a linear shape, a position detector scanning the measurement scale and obtaining position information, and a pair of adjustment blocks fixed to both ends of the measurement scale or the position detector and erected perpendicular to an extension direction of the measurement scale. The adjustment blocks are fixed to the axis drive part and are curved in the axial direction due to a temperature change.
