Title:
MAGNETIC POLISHING MACHINE
Document Type and Number:
WIPO Patent Application WO/2019/207656
Kind Code:
A1
Abstract:
The present invention comprises: a container (2) in which a material to be polished and a number of polishing pieces are housed; a plurality of rotating plates (5) which have magnets (7) attached thereto and which are rotatably arranged below the container (2); and a first rotating mechanism (6) that rotates the rotating plates (5) about the rotation axes A1 of the rotating plates (5). Since the plurality of rotating plates (5) are arranged below the container (2) in this manner, the polishing pieces are mixed together in the entire container (2) by the centrifugal force of the polishing pieces from the rotation of the rotating plates (5). For this reason, a reduction in the amount of the material to be polished above the central portions of the rotating plates (5) and in the vicinity of the rotation axes A1 of the rotating plates (5) is suppressed. Thus, it is possible to suppress polishing unevenness.
