Abstract:
A barrel polishing apparatus for polishing a surface of a work, comprising:a polishing medium receiving container having a polishing medium therein; means for rotating said medium container about a vertical axis for creating a continuous circumferential flow of said polishing medium therein; and a work supporting arm for attaching the work at a distal end thereof wherein the work supporting arm is rotatably connected to a supporting column provided outside of said polishing medium container, said work supporting arm being positioned away from a center of the polishing medium receiving container in a direction tangential to the polishing medium receiving container; wherein said work supporting arm is inclined relative to a surface of the polishing medium so that the work is faced diagonally toward a direction of said continuous circumferential flow of polishing medium when polishing said work, thereby creating a downward flow of the polishing medium along a lower surface of the work.
