[0040] The workflow of this application is as follows, with the loading and unloading device serving as both the starting and ending point. The material is loaded from the loading and unloading device onto the carrier slider. As it passes the water supply pipe area, water is supplied to the blind holes on the top surface of the second base on the carrier slider via the water supply pipe. The water supply pipe is made of a skeletal tube or a shaped metal tube directly aligned with the point requiring water supply. The carrier slider then moves to the area where the induction coil of the induction heater is located, where localized tempering is performed via electromagnetic heating. The water in the blind holes ensures that the second base does not overheat, and also ensures that the bits placed in the blind holes undergo localized tempering rather than complete tempering. After tempering, the bits enter the fan array area for cooling. Because this application uses a circular track, the cooled bits return to the loading and unloading device for unloading.
