Vibratory finishing machine having a helical and tubular container

摘要

A vibratory finishing machine includes a base having an upper face, coil springs mounted on the upper face of the base, a vibrator having an outer peripheral face and mounted on the base via the coil springs for vibration, a vibrating motor mounted on the vibrator, and a helical tubular container into which an admixture of workpieces to be finished and finishing media are loaded. The container has upper and lower flat superposed faces extending lengthwise and is helically wound on the outer peripheral face of the vibrator at a plurality of turns so that the upper and/or lower superposed faces of each turn of the container are superposed on the lower and/or upper superposed faces of the adjacent turn or turns respectively.
