US 2025/0389101 A1 · DURABLE CUTTING EDGES WITH WEAR RESISTANT WEAR INDICATOR

Abstract

A cutting edge of a machine is fabricated by cutting one or more grooves within a base cutting edge and incorporating one or more hard tiles in the grooves. An edge groove may be cut into a ground-engaging edge of the cutting edge and hard tiles may be disposed therein. Additionally, a face groove may be cut into a corner of the cutting edge, within which hard tiles may be disposed. At the face of the cutting edge, distanced from the ground-engaging edge, a wear indicator groove may be cut and wear indicator tiles may be disposed therein. Furthermore, laser-clad abrasion resistant material may be provided on a face of the cutting edge to improve the wear resistance of the face. Further still, the corners of the cutting edge may be rounded at its end(s) to remove the sharp corners that wear faster than the rest of the cutting edge.

Dependent claims

A cutting edge, comprising:

a ground-engaging edge;
an end edge;
a face extending up to the ground-engaging edge and the end edge;
a first wear indicator tile disposed within a first groove within the face, the first wear indicator tile at a predetermined distance from the ground-engaging edge;
and
a second wear indicator tile disposed within the first groove proximal to the first wear indicator tile, wherein the first wear indicator tile and the second wear indicator tile comprise tungsten carbide (WC) and cobalt (Co).
