Straight grinding fluids have been shown to have high performance but were not used in actual grinding because of the high possibility of fire hazards and thermal distortion of work. A dual-fluid supply method has been developed by the authors that makes such grinding fluids practically applicable. The method consists of supplying a straight grinding fluid from a Makitsuke nozzle (that stick the grinding fluid to the wheel surface) and, at the same time, directing a coolant on the underside of workpiece. The method has been applied successfully in high efficiency grinding (1200 mm2/min) using a CBN wheel, with the result of a grinding performance about 5 times better than that obtainable by the conventional method.
