According to the different frequency of the induction hardening for surface heating, it can be divided into the super high frequency(27MHz), high frequency(200～250kHz), medium frequency(2500～8000Hz). So because of the different frequency of the current of the induction hardening machine, the heating depth of current penetration is different too. The high frequency is mainly used for the surface hardening of the little size gears and axis parts because of the shallow depth of current penetration about (0.2-2mm). The super high frequency is mainly used for the surface hardening of the sawtooth, cutting edge and other thin workpieces.

Induction heating is the process of heating an electrically conducting object (usually a metal) by electromagnetic induction, through heat generated in the object by eddy currents. An induction heater consists of induction power supply (induction heater) and inductor (coil) that is a shaped to contour the part, and a work station where the part is held and presented to the coil.
