A method and apparatus (23) for vibro-treating an object (30). The method comprises the steps of controlling a relative displacement between a vibro-treating media (32) and a surface area of the object (30) to provide a vibro-treating effect; and, controlling movement of the object (30) relative to a surface of the vibro-treating media (32) whilst controlling relative displacement between the vibro-treating media (32) and the surface area of the object (30), according to one or more pre-determined conditions, to provide a substantially even vibro-treating condition over the surface area of the object (30).
