摘要

The device has an annular base (4) and a grindstone device (6) attached to the lower surface of the base. A coolant container that is open towards the interior in a radial direction is formed on the inner surface of the base. The coolant container extends continuously in a peripheral direction between an upper inclined surface and a protruding surface extending outwards below the upper inclined surface.
