The invention relates to the technical field of milling cutters, in particular to a wind driven generator rotor magnetic steel ladder groove machining milling cutter which comprises a milling cutter disc, a driving shaft and a first conveying unit. A plurality of groups of mounting grooves are formed in the outer edge of the milling cutter disc, and a cutting assembly is arranged in each group of mounting grooves. The cutting assembly comprises a cutting edge, the cutting edge is provided with a cutting face, and the cutting face is provided with a cutting end used for executing the cutting action. And when the driving shaft drives the milling cutter disc to axially rotate around the milling cutter disc, the cutting end starts deep groove machining immediately. After the cutting fluid in the containing cavity flows into the first flow channel, the first conveying unit can guide the cutting fluid to stably flow to the cutting end, so that the cutting end and the area, making contact with a workpiece, of the cutting fluid are efficiently cooled and lubricated. Therefore, through guiding of the first conveying unit, the flowing path of the cutting fluid on the cutting face is prolonged, the residence time of the cutting fluid on the cutting face and the cutting end is prolonged, efficient cooling and lubricating are achieved, the cutting temperature is remarkably reduced, and heating and abrasion of the cutting edge are reduced.
