Description

With SDF® generators, two different frequencies act simultaneously on the workpiece to be heated, causing the entire component to be induction-hardened with absolutely uniform depth and temperature. New precision – maximum flexibility The outstanding advantages of this patented method are especially evident when hardening complex components. Such as gearwheels, for example: While medium frequencies essentially penetrate more deeply into the gearwheel, primarily heating the tooth base, the high frequencies heat the tooth tip. This is why the SDF® method applies two different frequencies simultaneously to the workpiece to be heated. The entire component is heated with absolutely uniform depth and temperature.
