Latest Patents

Andreas Lumkemann holds a patent for a hob cutter with a coating and a method for coating hob cutters. The invention involves a hob cutter tool that features a specialized coating produced by a physical vapor deposition method. This method utilizes an atmosphere containing nitrogen, where an arc discharge is generated between an anode and pure aluminum and chromium cathodes. The vaporized aluminum and chromium are deposited onto the rotating hob cutter tool, creating a multi-layered coating composed of (AlCr)-nitride. The layers differ in their aluminum to chromium ratios, alternating to enhance the tool's performance. This innovative approach not only improves the tool's longevity but also its cutting efficiency.
