In Electrical Discharge Machining (EDM), a thin single-strand metal wire, usually brass, is fed through the workpiece. EDM is a thermal process, removing material from the two electrodes by melting or vaporization, along with pressure dynamics established in the spark-gap. Material is removed from the work piece by a series of rapidly recurring current discharges between the tool-electrode, or simply the “tool” or “electrode,” and the workpiece-electrode, or “work piece.” The process depends upon the tool and work piece not making actual contact.
- Brother H570A Wire
EDM
- Max speed of 300 mm2/min
- High speed automatic threading
- A 0.1 µm pitch optical linear scale (XY axes) and a 2.5 µm Ry surface roughness for highest machining accuracy in its class.
- Capable of machining medium and large parts, and complicated shaped parts due to a table stroke of 410 mm x 260 mm, up to 350 kg parts
- Indexing for multi-face machining.
