Problems solved by technology

[0002] At present, milling cutters used in mechanical processing are composed of cutting blades or cutting cutter bodies or tool holders or positioning holes. The cutting edge of the milling cutter has a single force in the feed direction, that is, a single force on one cutting edge The curved or straight shape of the cutting edge is composed of a single cutting edge. The cutting method of this cutting edge has a large resistance, resulting in a large overall destructiveness, so it is prone to chipping and accidents, and it is easy to cause waste products, which brings a lot of damage. Large losses, more serious and even casualty accidents

Abstract

The invention provides a composite milling cutter. The composite 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 composite milling cutter is characterized in that: on a 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 composite 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 composite 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 composite milling cutter are increased and prolonged to a largest value respectively, cost is reduced, and resources are saved.

Description

Technical field: [0001] The present invention relates to a compound milling cutter, which is used in mechanical processing of milling machines and the like. Background technique: [0002] At present, milling cutters used in mechanical processing are composed of cutting blades or cutting cutter bodies or tool holders or positioning holes. The cutting edge of the milling cutter has a single force in the feed direction, that is, a single force on one cutting edge The curved or straight shape of the cutting edge is composed of a single cutting edge. The cutting method of this cutting edge has a large resistance, resulting in a large overall destructiveness, so it is prone to chipping and accidents, and it is easy to cause waste products, which brings a lot of damage. Big losses, more serious even cause casualties. Invention content: [0003] The present invention is proposed in view of the above-mentioned problems, and aims to provide a new type of compound milling cutter, wh...
