Title:
BARREL POLISHING METHOD, AND CUSHIONING MATERIAL
Document Type and Number:
WIPO Patent Application WO/2023/162930
Kind Code:
A1
Abstract:
The objective of the present invention is to reduce wear of polishing stones without causing a deterioration in the polishing power of the polishing stones themselves or increasing the cost. This barrel polishing method is a method for polishing a workpiece (11) by means of polishing stones (12), by introducing the workpiece (11), the polishing stones (12), water (13), and a cushioning material (14) into a barrel tank (10), wherein a median diameter (D50) of the cushioning material (14) is 1.2 μm to 2000 μm, and the amount of cushioning material (14) introduced is 2 wt% to 30 wt% with respect to the water (13). Since the cushioning material (14) exhibits a cushioning effect when the workpiece (11) and the polishing stones (12) collide, and when the polishing stones (12) collide with one another, the polishing stones (12) are less liable to wear. Since there is no need to adjust the composition of the polishing stones (12) or to make significant process changes, the cost does not increase. Wear of the polishing stones (12) can therefore be reduced without increasing the cost.
