Title:
ナイフエッジ研磨装置
Document Type and Number:
Japanese Patent JP2006524586
Kind Code:
A
Abstract:
Two counter-rotating, intermeshing, toothed wheels grind opposite sides of an interposed blade to create or burrlessly sharpen a knife-edge on the blade. The wheels can be solid or comprised of a fixed stack of toothed disks, concentrically aligned, the teeth of each succeeding disk angularly offset in a common direction from the teeth of the next preceding disk to create a wheel having a plurality of uniform, elongated composite teeth around the circumference of the stack, the teeth being angled from the wheel's axis. Two such wheels, one with teeth angled in an opposite direction, can be counter-rotated and because of the oppositely angled teeth, are capable of intermeshing. The degree of intermeshing can be selectively varied to correspondingly vary the sharpening angle. The apex ridges of both the solid and composite teeth can be selectively profiled to sharpen non-uniformly, e.g. serrating a blade edge.
