Abstract
Abstract A vibratory finishing machine includes an elongated container supported at longitudinally spaced intervals for oscillator movement at a predetermined natural frequency and on an effective axis offset laterally to a vertical plane extending through the center of the container. In one form, the container consists of longitudinally aligned and rigidly connected sections each supported by a plurality of aligned spring beams mounted on a corresponding frame section so that each container section has substantially the same natural frequency of oscillation. A pair of opposing magnets are mounted on each frame section to effect vibration of an armature rigidly connected to the corresponding container section, and each armature is generally aligned with the corresponding spring beams. Each pair of magnets is separately controllable to provide for varying the amplitude of oscillation of each container section. The container may also be enclosed to provide a ball mill or may be provided with end openings for progressive finishing an elongated part.
