Abstract
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.
