HIGH FREQUENCY HEAT TREATMENT METHOD FOR PARTS WITH SHAFT

摘要

The present invention provides a high frequency heat treatment method for a part having a shaft, wherein a shaft of a portion such as a part applied to a transmission of a vehicle is high frequency heat treated to be surface hardening treated. The high frequency heat treatment method for a part having a shaft enables a high frequency heat treatment process and a cooling process which are uniform to an entire circumference of a shaft (3) in an object (1) to be processed which is put on a fixing jig (24) on a rotational plate (20) by using a high frequency heat treatment device (10) of a part having a shaft which comprises a rotation unit (12), a supply unit (13), a heat treatment unit (16), and a blowout unit (17), thereby ensuring stability of quality.
