Abstract
A vibratory barrel finishing machine comprises a single or multiple barrel arrangement of an elongated elliptical form in plan view including semicircular barrel sections at the opposite ends thereof and straight longitudinal barrel sections running in parallel and connecting between the opposite semi-circular barrel sections, the semi-circular barrel sections having descending-slope path in the direction of the flow of a mass (a mixture of unfinished workpieces and abrasive media) and straight barrel sections having ascending-slope path in the direction of the mass flow. The machine further includes workpiece guide means or workpiece advance control means which both provides the constant and smooth travel of the mass, particularly around the corners of the barrel structure, thus preventing the individual workpieces from impingement each other.
