Definition of VSR(vibratory stress relief)
It describes a physical process is this: that is tightly controlled using a vibration energy,
the metal work piece is processed to resolve the workpiece during and after the processing of
the internal and residual stresses occur dimensional changes resulting load capacity and resistance to change.
VSR（vibratory stress relief) to eliminate, reduce or homogenizing the residual stress of the metal workpiece, the workpiece
to improve resistance to static and dynamic load, the deformation resistance, stability,
efficacy superior dimensional accuracy.
