<p>A wire-cut electroerosion apparatus comprising a working tank (6) for containing a dielectric fluid having at least one wall with an opening (36) therein, and a lower arm (15) which is supported at one end on the outside of the working tank, extending through the opening and the tank being movable relatively to the lower arm in a sealing relationship. The working tank consists of a base container member (12) and at least one movable frame member (13,14). The base container member includes a rear wall with the opening therein and a low wall formed at the other three sides which is lower than the base of the workpiece. The movable frame member can be lowered using a pantagraph (20) to thereby easily access the workpiece and an electrode wire. <IMAGE></p> |
