The photo shows the hardening station of a motorcyle engine assembly
crankshaft induction hardening and reheating machine.

※At Fuji Denshi, we refer to tempering as reheating to differentiate from
furnace methods.

In the photo, two sections of the shaft are induction heated.

The spray quenching jacket is combined with the coil unit for a rapid
heating-quenching process.

To perform hardening and reheating with the same machine, the converter is
designed to switch between two frequencies.

Even with two heating-quenching cycles, the cycle time is kept under 1 minuteper workpiece.
