description	The invention discloses a tool for machining a step-shaped oil hole in a raceway grinding undercut and an electric spark machining method, relates to a machining method and tool for the step-shaped oil hole, and aims to solve the problems that the machining difficulty of the step-shaped oil hole in the raceway grinding undercut is increased, the machining efficiency is low and the percent of pass is low by adopting an electric spark technology in the prior art. The tool is adjusted, a workpiece is clamped through the tool, an electrode is calibrated, the workpiece is aligned, oil holes of the workpiece are machined, after one oil hole is machined, a locking screw is unscrewed, a workpiece seat is rotated by a corresponding angle relative to a base, the workpiece seat is inserted into the base again, the locking screw is screwed, and the next oil hole is machined. The equant tool is used for overcoming the defect of shaking a rotary table handle, angle errors and repeated positioning errors are avoided, and op
