Abstract
The utility model belongs to the field of milling cutters, and in particular relates to a stepped polishing milling cutter used for milling a hole, and the stepped polishing milling cutter machining a stepped shape. The stepped polishing milling cutter comprises a cutter handle, wherein the cutter handle is connected with a power device. The stepped polishing milling cutter is characterized in that a step cutting part is connected to one end of the cutter handle; the step cutting part comprises a first step cutting part, a second step cutting part and a third step cutting part; a transition conical surface is arranged between the second step cutting part and the third step cutting part; the diameter of the first step cutting part is less than the diameter of the second step cutting part, and the diameter of the second step cutting part is less than the diameter of the third step cutting part. The utility model designs a stepped polishing milling cutter, which is capable of machining a stepped hole shape once, and polishing the inner wall of the hole, so as to improve the quality of the inner wall of the hole and meet the subsequent assembly requirements; and the additionally arranged transition conical surface forms a chamfer surface on a workpiece, thus facilitating accurate location for other workpieces.
