Paper Title:
Study on the Mechanism of Prolonging Service Life of Tap in Low Frequency Torsional Vibration Tapping
  Abstract

The mechanism of prolonging service life of tap in low frequency vibration tapping was studied from two aspects of the reduction of wear and the insensitivity of the passivation of tap. Repeated cutting and separate type boundary lubrication improved the contact and lubrication status on rear face of tap. On the one hand, it greatly reduced the wear of rear face the tap, on the other hand, it markedly decreased the passivation sensitivity of tap to blunt radius and flank wear. With the interaction of two factors mentioned above, the service of life was prolonged greatly by low frequency vibration tapping.
