The VSR is used for mechanical weldments, castings and machined parts, which produce residual stress, affect the dimensional stability, stiffness, strength, fatigue life and machining performance of components, and even lead to cracks and profitable corrosion. It can eliminate the residual stress and prevent the deformation of the workpiece.

The VSR equipment of our company is rated speed 8000r / minr, rated exciting force 35KN, applicable to the weight range of VSR parts (0.1-50) tons. It is mainly used for stress removal of fan impeller.
