DESCRIPTION

Drilling machines are equipped with a vibration system which generates axial oscillations from the spindle rotation. To cope with different constraints, two vibration system technologies have been developed: one with eccentric discs (for automatic drilling unit) the other with a swashplate (for spindle).

BENEFITS

  • Improved remove of the chips
  • Improved productivity by decreasing tool breakdown
  • Simple and robust technology
  • Adaptation: Possibility to modulate oscillation frequency and amplitude
