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
