Publication number: 20220087109Abstract: A cutting element, in particular for abrasive cut material, is provided that includes a substrate that defines at least one cutting wedge which is formed by first and second wedge surfaces that intersect along a wedge edge. A cutting layer that extends over the first wedge surface and defines a cutting edge which lies on the wedge edge when new. The wear resistance of the cutting layer is greater than wear resistance of the substrate. The cutting layer is configured to define a blade-shaped protrusion that projects beyond the wedge edge due to wear of the substrate in the area of the second wedge surface to provide a self-resharpening cutting edge. The cutting layer or part thereof is formed by means of melt-metallurgical modification of an edge zone of the substrate by in-situ precipitation of finely dispersed inherent hard phases from partial melting of the edge zone of the substrate.Type: ApplicationFiled: September 17, 2021Publication date: March 24, 2022Applicant: Gebrüder Busatis Gesellschaft m.b.H.Inventor: Wolfgang Lutz

Patent number: 10668547Abstract: A saw blade for cutting stalk crops, such as for example maize or millet, has a planar flank and a facet flank and a sawing edge with a succession of saw teeth. The saw teeth are provided with a wear protection zone, the wear resistance of which is greater than that of a material of the base body of the saw blade. The wear protection zone is respectively located on the planar flank of each saw tooth. The saw teeth in the region of the tooth face have a cutting facet, starting from the facet flank. The cutting facet is configured at a distance from the planar flank of the saw tooth to form a blunt tooth cutting edge and, in a preferred embodiment, the cutting facet and the facet flank are configured without a wear protection zone.Type: GrantFiled: May 9, 2018Date of Patent: June 2, 2020Assignee: Gebrueder Busatis Gesellschaft m.b.H.Inventors: Wolfgang Lutz, Thomas Riegler
