In continuous industrial operation, the machine can achieve cycle times under 30 s for hardening of four-cylinder passenger vehicle crankshafts. Most crankshafts are manufactured in cast steel; some high-end crankshafts are produced with forged steel. This results in extremely short cycle times, even with large crankshafts and the patented induction hardening of split pin crankshafts are also possible. With induction, only the part to be hardened is heated. Cook Induction Heating Co. In response to a control command, the machine automatically configures itself for different spacings between main and pin bearings.
