(Cutting Sample)
Hitachi Electric Discharge Machining (EDM) wire is especially designed for cutting hard metals using the EDM process. Featuring superior electric properties, EDM Wire is the first choice for high-speed machining and cutting projects requiring surface precision.
Composition
Lead and other impurities degrade the performance of electrode wires. We have kept these at a minimum, using closely examined materials to improve electric discharge.
High dimentional precision
We use a diamond dice of precisely controlled hole diameter to limit wire diameter tolerance and roundness tolerance. Theses are both limited to 1µm.
Stable machinical performance
Both hardness and soft (annealed) material show a high stable value tensile strength with little deviation.
High surface quality
All our EDM Wire types feature a smooth flawless surface, free from irregularities. Hitachi EDM Wire has been subjected to a unique surface treatment ensuring that no brass powder (chips) are generated.
High cutting speed
Based on a process to optimize the percentage of Zine, which improves discharging properties, cutting speed can be increased (by up to 10%) under the same processing condition.
