徴としたフエライト磁石研削用ホルダ。 A ferrite magnet grinding holder for holding a plurality of ferrite magnets lined up in a straight line when grinding the outer and inner surfaces of substantially arc plate-shaped ferrite magnets using a rotating grindstone, the holder comprises a lower holder and an upper holder. The upper surface of the lower holder is formed into a convex arcuate surface that matches the inner surface shape of the ferrite magnet, and band-shaped raised portions are formed on the upper surface at regular intervals in the longitudinal direction to a height that is less than half the thickness of the ferrite magnet. A partitioned space in which one ferrite magnet is placed is formed between the band-shaped raised parts, and a vacuum suction hole is opened in each partitioned space, and the lower surface of the upper holder matches the outer surface shape of the ferrite magnet. A ferrite magnet grinding holder characterized in that it is formed into a concave arcuate surface, a similar belt-like protuberance is formed on the lower surface to form divided spaces, and vacuum suction holes are opened in each of the divided spaces.
