The invention relates to an electric discharge machine with a column which carries on its top cantilever the tool head with a holder for the machining electrode, having a work table for the workpiece to be machined and a container, fastened to the work table, for accommodating the dielectric working fluid. The invention is characterised in that bar-shaped elements for a light grille are fastened to the frame, which bar-shaped elements carry sensors, receivers or reflectors and of which the two nearest to the operating side can be turned down from a vertical working position into the inactive horizontal position. <IMAGE> |
