Benefits of NX Technology

  • High-speed pulse technology, which allows to get the following results:
      • Shorter machining times in jobs that involve very difficult flushing.
      • More homogeneous finish on large surface areas (VDI 20 – Ra 1.00 µm on 225 mm²).
      • Very deep grooves can be machined, with the highest quality and precision guaranteed (VDI 20 – Ra 1.00 µm up to 100 mm).
  • New SAAC system that maximizes generator performance in erosion work involving evolutive surface electrodes. It is particularly apt where the workpiece has little area at the outse.
