Spark Erosion

Spark Erosion is a high precision machining technique which has many benefits:

  • Spark ErosionVery intricate shapes can be achieved in the work piece
  • Component can be hardened and finished on the spark Eroder
  • No distortion on machined part
  • Square corners can be achieved
  • Broken drills and taps can be easily removed
  • Very fine finishes
  • Most metals can be sparked
  • Very accurate


A brief overview of spark erosion.
An electrode is manufactured, either from copper or graphite to the required component shape. The electrode then erodes the work piece via DC current through the machine.

The machine we have is a Charmilles 2-LC Spark Eroder with digital read out. Tank size 500mm x 300mm.
