Method and apparatus for sharpening a tool blade

摘要

A device for sharpening a tool blade has a pair of spaced guide rails and a bracket for mounting a sharpening stone on the guide rails. A carriage is slidably supported on the guide rails and has a pair of spaced slide plates adjustably supporting a blade angle plate thereon. A clamp mechanism secures the tool blade on the angle plate which is secured in an adjusted position for forming a primary angle on the blade cutting edge by reciprocal movement of the carriage along the guide rails. The angle plate and attached tool blade are readjusted on the carriage for subsequently forming a secondary angle on the cutting edge of the tool blade. Printed indicia adjacent a plurality of adjustment holes formed in the slide plates set the primary and secondary angles of the cutting edge. Mating surfaces on the carriage and guide rails set the amount of material to be removed from the blade during reciprocal movement along an abrasive sharpening material.
