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, and the helix milling cutter has high efficiency, high strength and a long service life. The helix milling cutter is provided with a cutter handle or a locating hole and a cutter head which 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 with the compound blade 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 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...
