Abstract

The paper deals the problem of generation of a drill torsional vibration during drilling, applying a new type of vibration quite simple design exciters of torsional vibrations, which operation is based on the interacting of permanent magnets situated on input and output elements. External torque of a machine spindle generates parametric torsional vibrations of the drill because of variable magnetic stiffness. Frequency of vibrations depends on rotation frequency of the spindle, the number of pairs of permanent magnets and the order of their poles placement.
