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 cutter has high efficiency, high strength, and a long service life and comprises a cutter handle or a locating hole and a cutter head. The cutter is characterized in that a definition is formed about the height relationship between a crack-resisting slitting platform or a high-efficiency slitting platform and an inside adjacent high-efficiency slitting platform; the included angle between a composite helix cutting face and an adjacent composite locating disintegrating platform is more than or equal to 90 DEG; or the height difference of two adjacent composite helix cutting faces is more than or equal to 0.01 mm, or less than four fifths of the thickness of an discharged chip, or less than or equal to a height accounting for 9 times of the cutting feeding amount; or the thickness of the crack-resisting slitting platform is more than 0.6 mm, or less than or equal to one third of the diameter of the milling cutter; or a helix groove is disposed at the composite helix cutting face.

Description

Technical field: [0001] The present invention relates to a composite milling cutter, which is used in machining of milling machines and the like. Background technique: [0002] At present, the milling cutter used in machining is composed of a cutting insert or a cutting tool body or a tool holder or positioning hole. The cutting edge of the milling cutter has a single force in the feed direction, that is, a single cutting edge The curved or linear shape of the cutting edge is composed of a single cutting edge. The cutting method of this kind of cutting edge has high resistance and causes great damage to the whole. Therefore, it is prone to chipping and revitalization accidents, and it is easy to cause waste products. Large losses, more serious and even casualties. Summary of the invention: [0003] The present invention is proposed in view of the above-mentioned problems, and aims to provide a new type of composite milling cutter, which has high cutting efficiency, high strength,...
