Abstract
This utility model relates to the field of stepped chamfering end mills and discloses a stepped chamfering end mill with a step-cutting mechanism. The bottom end of the end of the end mill is fixedly fitted with a fixed milling part, and a first milling part is detachably fitted below the fixed milling part. A second milling part is detachably fitted at the bottom end of the first milling part, and a disassembly / assembly mechanism is provided inside the second milling part. The disassembly / assembly mechanism includes an insertion block, which is fixed to one end of the second milling part that penetrates the first milling part. A connecting block is fixedly fitted to the top of the insertion block. This utility model, through the design of the connecting block, engaging groove, rotating plate, engaging block, fixed collar, through hole, and support rod, enables quick disassembly and assembly between the guide rail, fixed milling part, first milling part, and second milling part. If any component is damaged, a component of the same specification can be quickly replaced, avoiding the overall scrapping of the entire component due to damage, thus reducing costs.
