High Frequency Surface Hardening

High Frequency Surface Hardening is a process in which only the surface layer of the component at the desired thickness is heated by eddy currents and subsequently hardened. The thickness of the layer is, if desired, within the range from a few tenths of a millimetre to several millimetres. The result is a hard surface layer on the tough core of the component. The most common components this process is used for are camshafts, hydraulic pistons, gearboxes, shaft diameters for bearings, and the like. This process is carried out on a GV 80 (80 KW / 250 KHz) high-frequency machine aggregate.
