Influence of Ultrasonic Burnishing Technique on Surface Quality and Change in the Dimensions of Metal Shafts

Abstract EN

This paper presents ultrasonic burnishing as a mechanical surface treatment for improving the quality of rotating shafts.

Ultrasonic burnishing is a modern method for finishing workpieces to produce a good surface quality.

This process improves the surface quality and increases the surface hardness of the workpiece, and the surface roughness of the workpiece improves.

As a result, wear resistance and fatigue life increase.

Furthermore, these improvements are achieved without expensive equipment or long processing times.

In this paper the influence of the ultraburnishing technique on the change in diameter and its effects on the out-of-roundness of rotating shafts are investigated.

This paper also takes a look at the magnitudes of the improvement of the surface roughness as a result of using ultrasonic burnishing.

Three different materials, aluminium, 34-CrNiMo6 tempering steel, and S355J2 structural steel, are examined.

The results showed that ultrasonic burnishing is a treatment that improves the quality of components.

Ultrasonic burnishing also has a reducing effect on the final diameter and out-of-roundness and increases the hardness of the workpiece.

It can also be stated that the material of the workpiece does not have a significant effect on the magnitude of the reduced surface roughness values.
