Spray arrangement for wet grinding machine - has internal teeth in elastomer segment which deflect coolant back against workpiece

摘要

The spray arrangement incorporates a segment which is made from an elastomer. The face of the segment which is opposite the cylindrical surface which is being ground, has a number of teeth or serrations which run parallel to the centreline of the workpiece. The teeth on the segment have a sloping surface at one side, so that coolant which is flung off the workpiece by centrifugal force is deflected back again against the workpiece. The radius of the segment can be adjusted by means of a screw to suit the radius of the workpiece. Coolant is supplied to the workpiece from the inside of the segment.
