According to the machining method of the slewing bearing, firstly, a first powder metallurgy raw material is used for being pressed into an inner ring inner layer component and an outer ring outer layer component through powder metallurgy, and the periphery of the inner ring inner layer component and the inner periphery of the outer ring outer layer component are provided with a plurality of evenly-distributed tooth-shaped protruding parts so that the contact face of the inner layer and the outer layer can be enlarged; then the inner ring inner layer component and the outer ring outer layer component are taken out and put into a secondary forming mold, a second powder metallurgy raw material is put into a gap, the inner ring outer layer component is pressed on the outer side of the inner ring inner layer component to form an inner ring of an integrated structure, and the outer ring inner layer component is pressed on the inner side of the outer ring outer layer component to form an outer ring of an integrated
