Abstract
A wire cut electric discharge machine (10) is equipped with a work table including a horizontal slide table (20) mounted on a metallic bed (14) of the wire cut electric discharge machine (10), and a work rest (22) fixed to the upper surface of the horizontal slide table (20). The horizontal slide table (20) and the work rest (22) are formed of an electro-conductive ceramic material to connect the work table directly electrically to the grounded metallic bed (14) so that the work table is held at ground potential without increasing reactance (L).
