Abstract
An electrical discharge machining apparatus in which a workpiece is machined by generating an electrical discharge between the workpiece and a facing electrode immersed in a machining liquid. A blower is provided for forcing cooling air into the interior of a bed, a column, and a head of the apparatus to prevent thermal displacements between the electrode and the workpiece and thus ensure accurate machining. The blower may also be used to cool the machining liquid.
