Crankshaft hardening A guide to the benefits of induction heating

EFD Induction crankshaft hardening systems are a proven way to meet stringent specifications, while at the same time minimizing costs. Available in four machine types, these systems offer compelling technical and commercial benefits. Fillet hardening capability Active power variation dynamically adjusts the power in accordance with the crankshaft’s angle of rotation during heating. The result is minimized distortion, as active power adjustment limits heat seepage. The feature also enables inductive fillet hardening—a process that contributes to making smaller, lighter, more fuel-efficient...

The EFD Induction range of crankshaft hardening systems Our crankshaft hardening systems are divided into four types: drum, robot, heavy and conveyor. Each type is modular, making it easy to adapt to changing requirements. Automatic cycles, CNC or PLC controls and realtime process monitoring are standard for each type—as are innovations that minimize Total Indicated Run-out. Drum type This system is designed for truck and off-highway crankshafts up to a maximum length of 1,5m. Singleand double-head, and single- and twin-tank versions are available. Heavy type The heavy type is for...
