Title: The Innovative Mind of Staffan Söderberg
Introduction: Staffan Söderberg, an accomplished inventor based in Huddinge, Sweden, is making waves in the field of cutting tool technology. With a keen focus on enhancing metal machining processes, his innovative contributions are transforming industry standards.
Latest Patents: Staffan holds two significant patents that showcase his expertise in the development of coated cutting tools. The first patent is for an Al2O3 coated cutting tool, which involves a coated CBN cutting tool designed for metal machining. This tool features one or more CBN bodies, potentially with a carbide backing. The coating consists of multiple layers of refractory compounds, with at least one fine-grained, crystalline γ-phase alumina layer (Al2O3) having a grain size of less than 0.1 µm. The deposition of this aluminum oxide layer utilizes a Plasma Activated Chemical Vapor Deposition (PACVD) process, where plasma is generated by a bipolar pulsed DC voltage applied across two electrodes connected to the tool substrate.
The second patent describes a PVD Al2O3 coated cutting tool, which also targets the metal machining sector. Similar in design, this tool is composed of one or more CBN substrate bodies, with or without carbide backing. The layer covering the tool is made up of refractory compounds, with at least one layer being fine-grained, crystalline γ-phase alumina (Al2O3) of grain size less than 0.1 µm. The Al2O3 layer is applied using a bipolar pulsed DMS technique (Dual Magnetron Sputtering) under substrate temperatures ranging from 450°C to 700°C.
