PROBLEM TO BE SOLVED: To provide grinding and superfinishing methods and a machining device capable of shortening the working time. SOLUTION: This machining method is so formed that grinding wheels and superfinishing grinding wheels are selectively aligned relative to respective machining counterparts of a work having a plurality of machining counterparts rotatably supported to a single axis and axially separated from one another, cross-feeding the grinding wheels and the superfinishing grinding wheels to the respective machining counterparts in the alignment position to grind the respective machining counterparts into the grinding size, and the grinding counterparts ground into the grinding size are superfinished into the superfinishing size. The superfinishing grinding wheels are made to wait in waiting positions with a prescribed interval separated from another machined part ground into the grinding size, at least, in the initial stage of the process for the grinding wheel grinding one of the grinding counterparts. The prescribed interval is determined based on the cross feed position of the superfinishing grinding wheel when another machining counterpart is machined into the superfinishing size.
