Abstract
Grinding with a fine abrasive wheel has problems with regard to vulnerability to loading and marked reduction of the dressing interval as the chip pocket is extremely small. In this report, the authors propose a new coolant supply method that combines the "kilosonic vibration coolant," which superimposes a kHz-order ultrasonic vibration with the "coolant flow guided flexible sheet method," which is as effective coolant supplying method, to achieve active reduction of loading. With application of this method to surface plunge grinding of copper and SKD11 using a GC1000 grinding wheel, it was shown experimentally that wheel wear accompanying adhesion of chips could be reduced. In addition, it was also confirmed that a good surface could be produced by miller face grinding on SCM435 using a GC3000 grinding wheel.
