Electrical discharge machine with at least one wire electrode and method of machining a workpiece in such a machine
First Claim
1. A wire guide head for an electrical wire discharge machine of the type wherein a wire is guided between an upper and a lower wire guide head, said wire guide head comprising:
- a body that is at least partially spherical, the body having a wire passage defined therethrough;
a wire guide disposed in said wire passage for guiding the wire in said passage;
a support for rotatably supporting said body such that said passage can be directed in a plurality of directions; and
a drive means for spherically rotating said body to adjust the direction of said passage.

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.
