Problems solved by technology

[0002] At present, the helical milling cutter used in mechanical processing is composed of a helical cutting blade, a tool handle or a positioning hole, etc. The cutting edge of the helical milling cutter has a single force in the feed direction, that is, a single force on one cutting edge. The curved or helical shape of the cutting edge is composed of a single cutting edge. The cutting method of this cutting edge has a large resistance and causes great overall destructiveness, so it is prone to chipping and accidents, and it is easy to cause waste products and bring Great losses, more serious and even casualty accidents

Abstract

The invention provides a helix milling cutter with a compound blade. The helix milling cutter is high in efficiency and strength, and long in service life, and is provided with a cutter handle or a locating hole and a cutter head. The cutter handle or the locating hole and the cutter head are connected with each other or integrated together, and the cutter head is integrally provided with a plurality of cutter stripes or cutter bodies or helix cutting stripes. The helix milling cutter provided with the compound blade is characterized in that: on a cutting face or helix cutting face arrange toward the helix direction, a triangle groove or a trapezoid-shaped groove, or an arc triangle groove or an arc trapezoid-shaped groove is arranged, or an arc-shaped convex, or an inclined convex and concave is arranged, and at least one grade bottom or side part is provided, a plurality of internal inclined cutting faces arranged with an angle more than 90 DEG and less than 180 DEG with the helix cutting face are provided, or a plurality of compound helix cutting faces; or extending of the arc-shaped convex or the inclined convex forms a compound locating resolution platform which is connected with an internal compound helix cutting face, forms a plurality of internal inclined blades or side concave blades, or side inclined blades, so that cutting stress is inclined toward inside, force arm is reduced, outside cutting resistance is resolved, cutting efficiency and service life of the helix milling cutter are increased and prolonged to a largest value respectively, cost is reduced, and resources are saved.

Description

Technical field: [0001] The invention relates to a compound edge helical milling cutter, which is used in mechanical processing of milling machines and the like. Background technique: [0002] At present, the helical milling cutter used in mechanical processing is composed of a helical cutting blade, a tool handle or a positioning hole, etc. The cutting edge of the helical milling cutter has a single force in the feed direction, that is, a single force on one cutting edge. The curved or helical shape of the cutting edge is composed of a single cutting edge. The cutting method of this cutting edge has a large resistance and causes great overall destructiveness, so it is prone to chipping and accidents, and it is easy to cause waste products and bring A lot of losses, more serious even cause casualties. Contents of the invention [0003] The present invention is proposed in view of the above-mentioned problems, aiming at providing a novel compound edge helical milling cutte...
