Abstract
An electrical discharge machine with at least one wire electrode (30) in which the wire electrode (30) runs between two guide heads (10,10'). At least one, in particular, both, guide heads (10,10') are formed to be at least partially spherical. At least one of the guide heads (10,10') is seated in a manner suited for spherical rotations. Alternatively or additionally, a drive means is provided for the spherical rotation of at least one guide head (10,10'). The spatial position of the wire electrode (30), in particular, its conical angle, can be adjusted completely or essentially by subjecting the two opposing spherical guide heads (10,10') to spherical rotations and/or a modification of spacing.
