Abstract:
1. In combination with a grinding disk rotatable about an axis 10 to grind a workpiece and having an outer periphery through which cooling liquid is projected radially on rotation of the disk, a shield assembly comprising: a shield juxtaposed with a sector of the grinding disk and formed with a collecting groove closely surrounding a portion of the outer periphery of the disk and forming therewith a passage extending angularly in a rotation direction of the disk from an intake end to an output end, the groove being so closely spaced from the disk that, on rotation of the disk, liquid exiting radially from the outer periphery is propelled angularly as a stream along the groove toward the output end thereof; and nozzle means in the shield at the output end for intercepting at least a portion of the stream and directing it as a substream through a nozzle passage at a location generally where the periphery of the disk engages the workpiece.
