ABSTRACT:
A travelling-wire electro-erosion machine which has a head assembly comprising a tubular support formed with a plurality of roller guides positioned to define a path for a travelling wire forming an electrode for electroerosion. Above the tubular support, there is provided a boxlike housing with a supply wheel and a takeup wheel for the wire and a bevel gear on the tubular support cooperates with a pinion on a motor which enables rotation of the entire assembly. A worm-gear arrangement may be used instead of the bevel gears and a different construction of the guide rollers may be provided as well, e.g. on the downwardly extending projection from the tubular body.
