To solve the big bulk, high cost and short life span problem of current vibration tapping and reaming system , and to promote application of the high performance vibration tapping and reaming technology, they proposed a wedge type torsional vibrator, which is of much smaller pressure angle, more compact,and which is symmetry in construction and easy to be fabricated.

Affected by some certain factors,it will appear flaws that hole enlarges when the centre of workpiece deviated from the centre of reaming.

Technology discussion on aperture increment of reamed hole;

This paper analyzes the main factors affecting the reamed hole quality and puts forward the control methods for hole reaming quality.
