Scale-like dense-tooth diamond coating milling cutter for composite material

Abstract

The invention relates to a scale-like dense-tooth diamond coating milling cutter for composite material. A plurality of circumferential cutting edges are arranged on a cutter body in the circumferential direction, right spiral chip removal grooves are formed among the circumferential cutting edges, protective cutter edges with shallow-groove-shaped structures are arranged on the right spiral chipremoval grooves, circumferential cutting edge backs are formed on the cutter body through the right spiral chip removal grooves, left-handed left spiral chip removal grooves are formed in the circumferential cutting edge backs, a plurality of end cutting edges are arranged at the front end of the cutter body, and chip containing grooves are formed among the end cutting edges. According to the scale-like dense-tooth diamond coating milling cutter for the composite material, a left spiral and right spiral crossed scale-like structure is adopted, the groove bottoms of the left spiral chip removalgrooves and the right spiral chip removal grooves are arc-shaped, the chip removal space is enlarged, the flowing speed of chips is increased, the chips are cut off and extruded through the right-handed sharp face and the left-handed sharp-breaking face, machined surface smoothness is guaranteed, burrs and delamination phenomena are avoided, the material removal amount of each tooth is reduced, multiple layers of diamond coatings are coated, so that the hardness of the surface of the cutter is enhanced, the abrasion of the cutter is reduced, and the machining cutting speed and the material removal efficiency are improved.

Description

technical field [0001] The invention belongs to the technical field of milling cutters, in particular to a scale-shaped fine-tooth diamond-coated milling cutter for composite materials. Background technique [0002] Due to its high specific strength, high temperature resistance, friction resistance and corrosion resistance, carbon fiber reinforced composite materials are more and more used in aerospace skins, structural parts, interior parts and other components. superior performance. Currently commonly used carbon fiber reinforced composite materials have single-layer structure and laminated structure (carbon fiber + aluminum alloy + carbon fiber or carbon fiber + titanium alloy + carbon fiber). Carbon fiber reinforced composites have the characteristics of poor thermal conductivity, anisotropy and laminated structure, which lead to the disadvantages of excessive milling force, serious tool wear and difficult to guarantee processing quality during milling, which seriously ...

Problems solved by technology

Currently commonly used carbon fiber reinforced composite materials have single-layer structure and laminated structure (carbon fiber + aluminum alloy + carbon fiber or carbon fiber + titanium alloy + carbon fiber). Carbon fiber reinforced composite materials have the characteristics of poor thermal conductivity, anisotropy and laminated structure, which lead to the disadvantages of excessive milling force, serious tool wear and difficulty in guaranteeing processing quality during the milling process, which seriously affect its popularization and application.
