State-of-the-art induction technology for crankshaft hardening plants

Crankshafts are used in combustion engines, transforming the con rod’s stroke into a rotatory motion for driving the axle shaft. Along with this, torsional and flexural fatigue appears and demands a special heat treatment process. The induction hardening with a rotating crankshaft has mostly replaced competitive methods and provides the engine builders with a flexible production process for varying geometries, different hardening zones as well as increasing production rates.
