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.
