Minimal distortion and with the highest precision
The crankshaft is a key part in engine construction. New requirements due to lightweight automotive construction and higher efficiency in engine technology require precision within ever tighter tolerances when hardening crankshafts.
Crankshafts must also have combined material properties: high-precision inductively hardened surfaces for wear-free and long-lasting running properties and elasticity of the component body for high torque absorption. Tread hardening improves wear resistance. The radius hardening also offers an increase in the bending fatigue strength of the crankshaft, which is required for high-performance crankshafts as well as for medium-sized and large crankshafts. It is used, among other things, in cars and trucks and as a large crankshaft for locomotives, ship propulsion systems or for large diesel engines for generators, compressors or pumps.
In the field of induction hardening systems for crankshafts, SMS Elotherm is one of the market leaders and has a great deal of expertise, which has led to an international establishment in the system business. Hardening technologies that are tailored and optimized to customer or workpiece-specific requirements, such as processes that minimize distortion, are far superior to conventional methods.
SMS Elotherm has developed applications especially for the inductive hardening and tempering of crankshafts, which are available to our global customers depending on the application and size of the crankshaft. All hardening systems are built with modular assemblies, so that important details can also be adapted without major additional costs and thus bring the greatest possible benefit to the system operators.
