Spark Eroding. Co. UK
On Site Spark erosion or Spark eroding or electro metal disintegration for the removing of broken
bolts, studs, drills, taps or extractors. The removal of broken drills, taps, extractors, bolts etc.,
is achieved by creating an electric spark between the broken item and the electrode which is held
in a vibrating head. The spark at the tip of the electrode and the item to be removed reaches
almost 5000 degrees Centigrade. Flooding with coolant creates a thermal shock, reducing the
heated material of the broken item to powder which is flushed away. No discernable heating of the
 parent material occurs, and there is no distortion of the parent metal when removing the broken
 drill, tap or extractor.

Spark erosion can be carried out in house, or at your site, anywhere,
subject to call out charge, and is perfect for removing broken taps,
broken drills and broken extractors, as well as broken bolts and studs.
By prior arrangement, we can also work on small transportable items,
either sent by carrier or your own transport
