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

A clean cut with no damage to the work piece with drills and taps

action of electrode disintigrating tap 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.

tap after spark eroding 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.
