Abstract
A device is enclosed which is suitable for supplying grinding fluid to an apparatus for generating curved surfaces by means of a rotating grindstone, and which supplies grinding fluid to the grinding point under optimum conditions as the grinding point moves. It includes a means for turning nozzles, which discharge grinding fluid onto a grinding point from a fixed direction, about the axis of the grindstone, and is able to constantly ensure a sufficient supply of grinding fluid to the grinding point by controlling the turning so that the nozzles are always pointing in a fixed direction relative to the grinding point so that the tendency of clogging and wear of the grindstone is diminishes.
