Technical scheme: for reaching above-mentioned purpose, a kind of Stepped Reamers processing soft magnetism stainless steel extension bar endoporus described in the utility model, including shank and blade, molding blade at the bottom of described blade head end providing holes, is provided with aperture molding blade in the middle of blade, molding blade at the bottom of hole and be provided with fraising blade between the molding blade of aperture, blade side is additionally provided with side and cuts sword, described side is cut sword and is provided with anterior angle, and the angle of anterior angle is 10 °, and chip area is spirally extended to blade afterbody from blade head。
Preferably, it is 2mm-3mm that the across back of sword is cut in described side, and to cut the quantity of sword be 3 in described side。
Preferably, described shank and blade are one-body molded, and molding blade at the bottom of described hole, fraising blade, aperture molding blade are one-body molded and stepped。
Preferably, molding blade at the bottom of described hole is 135 ° with fraising blade angle。
Preferably, described aperture molding blade includes 3 sections, and first paragraph and horizontal line angle are 14 °, second segment and horizontal line, and the 3rd section is arc section。
Compared with prior art, the beneficial effects of the utility model are:
(1) a kind of Stepped Reamers processing soft magnetism stainless steel extension bar endoporus described in the utility model, it is 10 ° that the anterior angle of sword is cut in described side, keen edge is cut in side, during cutting light, being greatly improved working (machining) efficiency, the design that width of land is 2-3mm is cut in side simultaneously, it is ensured that the robustness of blade, prevent blade from exerting oneself excessive fractureing when boring, affect cutting-tool's used life。
(2) a kind of Stepped Reamers processing soft magnetism stainless steel extension bar endoporus described in the utility model, molding blade at the bottom of collection hole, fraising blade, aperture molding blade are one-body molded stepped is distributed in blade, multi-step process concentrates on and carries out on a cutter, both can guarantee that the crudy of product, decrease the loaded down with trivial details of tool changing simultaneously, improve work efficiency。
