The invention belongs to the technical field of part processing, and particularly relates to a part surface high-frequency quenching technology. The part surface high-frequency quenching technology comprises the following steps that the first step, a workpiece is cleaned, specifically, impurities and dust on the surface of the workpiece are removed by cleaning fluid, then drying is conducted, andthe drying time ranges from 40min to 50min; the second step, rapid heating is conducted, specifically, the cleaned workpiece is clamped by a clamp and then is put into an inductor which is formed by hollow copper pipes in a winding mode, the clamp can be rotated, the alternating current with the frequency ranging from 1000Hz to 16000Hz is provided, the induced currents with the same frequency areformed on the surface of the workpiece, and therefore the surface or the local portion of the part can be rapidly heated; the third step, cooling soaking is conducted, specifically, the temperature ofthe surface or the local portion of the part is detected by a temperature sensor, and after the temperature ranges from 1000 DEG C to 1100 DEG C, cooling soaking is conducted on the part through liquid spraying holes of the inductor; and the fourth step, quenching is accomplished, the hardness of the surface or the local portion of the part is detected, specifically, the hardness of the surface or the local portion of the part is detected by a hardness detector, and after the requirement for the needed hardness is met, the quenching working procedure is accomplished.
