Abstract: The method is for profiling blades (406) with a belt (402) grinding profiling machine (400). The blades (406) are mounted into a vise (432). A vertical position of the template (404) is adjusted by rotating the rotatable knob (448). The motor (408) is turned on to rotate the grinding belt (402) over the grinding wheel (410). The guide wheel (424) engages the underside profile (420) of the template (404). The guide wheel (424) of the template (404) guides movement of the grinding wheel (414) mounted on the common axle by moving the guide wheel (424) along the underside profile (420) of the template (404). The grinding belt (402) grinds material off the underside of the blade (406) until a portion of the underside profile (420) of the template (404) is copied to the underside (422) of the blade (406).
