An automobile drive axle tube blank grooving processing method comprises the following steps: step one, drilling holes on two processing surfaces of the automobile drive axle tube blank, wherein the diameter of the holes is the width of grooves, and the distance between two holes in the same processing surface is the length of grooves; step two, after drilling holes, milling the holes to a certain distance to the direction of the tube blank by drilling bit in the axial direction of the tube blank; step three, using a combined cutting tool to cut two sides of the groove on one processing surface; step 4, overturning automobile drive axle tube blank, using the combined cutting tool to cut two sides on the groove on the other processing surface and accomplishing the processing. The method can not only solve the technical problem of residual R arc at two ends of the grooves after the competition of processing by using metal saw to cut groove in the prior art, but also can be completed by adopting conventional equ
