FLOW BARREL POLISHING DEVICE AND POLISHING METHOD

摘要

A flow barrel polishing device has a hollow cylinder-like fixed container (1) and a rotary table (2) horizontally rotated with a sliding section gap (3) formed at the bottom of the fixed container (1). Work and media are placed in the fixed container (1) and the rotary table (2) is horizontally rotated. Then, the work and the media flow in a whirling manner to form a mass (M) and the work is polished. A fixed or rotatably supported hollow cylinder (4) is provided on the rotation center of the rotary table (2), and by this, the outer peripheral surface of the mass (M) is made to be in contact with the inner peripheral surface of the fixed container (1) and the inner peripheral surface of the mass (M) is made to be in contact with the outer peripheral surface of the hollow cylinder (4), thereby the work in the mass (M) is polished.
