Spark Erosion Services

Spark erosion (also sometimes called Electro Discharge Machining) is used to machine complicated shapes from a range of materials. The process works by placing the workpiece between two electrodes which are separated by a dielectric liquid, which acts as both a conductor and a cooling agent. These electrodes produce electric discharge sparks to produce the heat needed for a controlled melting of excess material to create the desired part. With spark erosion, there is no mechanical abrasion found in CNC milling and turning.

Here at I&G Precision Engineering we offer precise spark erosion services to manufacture complex shapes in extremely hard materials. With spark erosion we commonly produce:

  • Blind keyways
  • GearsSplines
  • Complex forms
  • Press tools

Using our in-house technology for spark erosion, we can produce both high volume batch components along with prototype parts on a timescale to suit you. Our factory near Swansea in South Wales typically produces between 600 and 700 components per month, with each one undergoing extensive quality inspections before shipping.
