Document Type and Number:
WIPO Patent Application WO/2020/177295
Kind Code:
A1
Abstract:
Disclosed is an apparatus for the batch polishing of workpieces, the apparatus comprising an annular cavity (7), in which several workpieces are mounted, magnetic abrasives (12), which are arranged in the annular cavity (7) and used for polishing the workpieces, and multiple magnet sets, which are used for generating a magnetic field for the magnetic abrasives (12) in order to remove a surface material of the workpieces, wherein each of the magnet sets comprises magnets (6) arranged on both inner and outer sides of the annular cavity (7) and configured to rotate around the axis of the annular cavity (7). The apparatus can ensure a high-precision polishing characteristic of magnetic-field-assisted polishing, realizes the function of high-precision polishing of a large batch of workpieces, can be used for the surface treatment of alloys, ceramics, glass and various nonferrous materials, and can also be used for a finishing process of a complex porous surface.
