SHARPENING A KNIFE BLADE

摘要

A method and apparatus (10) for grinding a knife blade (66) to form a sharpened edge. The blade (66) is held in a fixture (56) including a self-centering clamp (57) with a pair of jaws (96, 98) gripping the knife blade (66) by engaging opposite sides (76, 78) of a part of the blade (66) tapered toward an edge location, and holding the blade (66) so that the intended edge location of the blade is in a desired location with respect to the fixture (56). This permits use of profiled grinding wheels (32, 34) of hard material mounted on a carriage under computer control to grind an edge bevel accurately on each side of the blade, forming a sharp edge.
