Two-edge pressure-type end mill

Abstract

The invention relates to the technical field of a cutter for cutting machining, in particular to a two-edge pressure-type end mill. The two-edge pressure-type end mill comprises a cutter handle and an edge part which is arranged on the front end of the cutter handle, wherein the edge part is formed by a plurality of sections of spiral structures which are identical in structure and are connected with one another from front to rear, each spiral structure is formed by screwing a left-handed edge body and a right-handed edge body relative to the same axis for half circle, a plurality of spiral scale backs are uniformly arranged on the back surface of each spiral cutter body, a seamed edge of each spiral cutter body and a seamed edge of each scale back are respectively provided with a cutting edge, a spiral cutter withdrawing groove is formed between the two spiral cutter bodies, the seamed-edge side edges of all the spiral cutter bodies form a spiral cutting edge of the two-edge pressure-type end mill, and the front end edges, on the front end of the edge part, of the spiral cutter bodies are intersected to form a mill end edge. The two-edge pressure-type end mill is specially used for cutting a composite material, is free of layering, burrs and the like in the machining process, and is high in machining quality.

Description

technical field [0001] The invention relates to the technical field of cutters for cutting, in particular to a double-edged compression end mill. Background technique [0002] With the advancement of science and technology, various composite materials are more and more used in the industry, so it is necessary to carry out cutting processing on the corresponding materials. At present, conventional end mills are used for processing composite materials. Conventional end mills It is easy to generate vibration during processing, which will cause burrs on the cut composite material, and the composite material will expand and delaminate under the action of cutting force, which will easily cause damage to the tool and scrap the processed workpiece, especially when cutting soft plastic composite materials. When laminating materials, delamination and burrs often occur. Therefore, an end mill specially designed for cutting composite materials needs to be applied urgently. Contents of...
