Abstract
Abstract A self-separating finishing machine for finishing of parts with finishing media, having a rotatable housing comprising a finishing chamber and a storage chamber and a foraminous member therebetween, wherein the housing is rotatable from a first and finishing position to a second and media-separating position and to a third and parts-ejection position, and wherein vibratory means, preferably variable-intensity vibratory means, is operatively associated with said foraminous member for vibration of said foraminous member, especially at different intensities, when said housing is in different positions of rotation, such machine embodying a particularly advantageous type of variable-intensity vibratory motor especially adapted for use in such machine, and a method of finishing involving the impartation of various intensities of vibration to the foraminous member at different stages of the process, e.g., when the housing is in different positions of rotation, are disclosed.
