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 and washing it 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.
The Disintegrator Process |
 |
Because the high temperature arc between the
electrode and the work piece is continuously quenched by coolant, there is no
softening of material around the
hole. The hole created by the arc takes the same shape as the
electrode used. BENEFITS to you: • Reclaim expensive parts quickly, easily. • No re-manufacturing of parts. • Flexible working hours. • Quick response. • Eliminate production overruns and late deliveries. • Scrap reclamation. |
The spark eroding process has burnt out the centre of
a broken tap leaving only the flutes to be removed, not damaging the
parent metal. It also removes the centre only of a broken drill, but may
do some damage to the threads of a broken bolt or stud, which then would need
to be reclaimed by the insertion of a wire insert.
