Zusammenfassung:The invention discloses a machining method for stepped ring grooves of a supercharger sliding bearing. The machining efficiency is higher, and the machining cost is lower. The machining method for thestepped ring grooves of the supercharger sliding bearing comprises the following steps that S1, the supercharger sliding bearing is prepared, the four stepped ring grooves which are evenly arranged in the circumferential direction are to be machined in the supercharger sliding bearing, and the stepped ring grooves are integrally in a fan shape and comprise the upper-layer ring grooves and the lower-layer ring grooves communicating with the outer sides of the upper-layer ring grooves; S2, holes are drilled in the circle centers, to be subjected to fillet machining, of the two ends of each stepped ring groove, and the finish machining allowance of subsequent fillets is reserved; S3, a sinking table is milled at the drilling position of one end of each stepped ring groove to serve as a cutting point of a milling cut
