Patent Number Title Of Patent Date Issued
D432396 Wire spool October 24, 2000
6566622 Wire electrode May 20, 2003
A wire electrode, and a method for making it, for use in spark-erosive cutting having an electrically conducting core essentially absorbing the tensile forces. The wire electrode has furthermore a coating which wears during erosion, which coating consists of two layers. Such a wire e
6447930 Wire electrode and process for producing a wire electrode, particular for a spark erosion proces September 10, 2002
In order to produce a wire electrode having a core consisting of a copper/zinc alloy and to produce a specific sheath layer, the sheath layer is coated onto the core at a temperature at which no diffusion occurs. The wire electrode is subsequently heated at a heating speed higher than
6348667 Wire electrode for the spark-erosive cutting of hard metal February 19, 2002
A method and a wire electrode for the spark-erosive cutting of hard metal, whereby the wire electrode has a core and at least one outer coat surrounding the core and wearing during cutting. To avoid corrosion, as, for example, pitting, a wire electrode is chosen, the wearing outer coat
5762726 Wire electrode and process for producing a wire electrode, particular for a spark erosion proces June 9, 1998
In order to produce a wire electrode having a core consisting of a copper/zinc alloy and to produce a specific sheath layer, the sheath layer is coated onto the core at a temperature at which no diffusion occurs. The wire electrode is subsequently heated at a heating speed higher than
