Peel grinding may be considered as one end of the HEDG spectrum of processes. Because a narrow wheel contact width is employed and rather more moderate depths of cut, power consumption is much lower than in HEDG. Grinding wheel wear is minimized and improved grinding ratios are achieved by using high-speed superabrasive wheels.
