The method is for profiling blades with a belt grinding profiling machine. The blades are mounted into a vise. A vertical position of the template is adjusted by rotating the rotatable knob. The motor is turned on to rotate the grinding belt over the grinding wheel. The guide wheel engages the underside profile of the template. The guide wheel of the template guides movement of the grinding wheel mounted on the common axle by moving the guide wheel along the underside profile of the template. The grinding belt grinds material off the underside of the blade until a portion of the underside profile of the template is copied to the underside of the blade.

Described is an apparatus for finishing metallic and non-metallic surfaces by abrasion techniques. Described is an apparatus configured for finishing a zone on the surface of a bladed article of manufacture, wherein the apparatus comprises one or more channels having a cross-sectional profile including at least one finishing area to finish an operative zone of the article that optimizes a clearance portion of the article, wherein an angle of each finishing area of the cross-sectional profile is substantively the same as an optimal clearance angle of the article, wherein the apparatus is configured to position the operable zone of the article along the angle of the finishing area during sharpening.
