Typical problem of mechanical couplings with stud bolt seized can be solved only by destruction of stud, without any damage to threaded hole. Destruction can be carried out by spark erosion (EDM) instead of mechanical progressive drilling which requires at least a time 5 times bigger.
Process can be performed in any position (included overhead), no limit on size by progressive cut.
Special Add-ons and Customization
Available several shape of electrodes to allow any kind of destruction in the shortest time.
Automatic feed applied to reach high precision and low execution time.
Available for anchor / positioning system and shape of cut.
