Example Embodiment

[0015] figure 1 It is a three-dimensional drawing of a non-equidistant texture finishing grinding reducing turning blade. The blade body is designed as an 80° diamond turning blade with a radius of 0.8mm and a material of cemented carbide.

[0016] figure 2 These are the three-dimensional magnified micro-textures, respectively, the magnified micro-textures of the rake surface and the micro-texture of the flank.

[0017] in image 3 Among them, there are non-equidistant arc-shaped groove micro-textures (1) on the rake surface, and the groove widths of the micro-textures are different. The size of the micro-texture conforms to the arithmetic sequence with the first item of 20μm and the tolerance of 5μm. The texture pitch size conforms to the arithmetic sequence with the first item of 60μm and the tolerance of 10μm. The distribution method is that the closer to the cutting edge, the denser the texture, and the smaller the width of the texture groove. When cutting nickel-based supera...

Abstract

The invention relates to a non-equidistant texture finishing abrasion-reducing turning blade. The blade is provided with non-equidistant micro-textures with unequal groove widths and intervals on thefront blade surface and rear blade surface, and the distribution mode of the non-equidistant micro-textures is designed to be dense in front and sparse in back according to the stress distribution condition of a cutter during cutting. The closer the texture is to a cutting edge, the denser the texture is and the smaller the groove width is, thus the problem of breakage of the micro-textures is solved, the abrasion and breakage of the cutter are reduced, and the cutting force is reduced. A cuttings breaking table is machined on the front face of the blade to control cuttings breaking, the cutting edge of the blade is a curved edge, the flow direction of cuttings is changed, and the cuttings are prevented from winding or scratching a workpiece. A volume groove is designed on a polygonal convex table of the front blade surface, and a guide groove enhances the heat dissipation capability of the blade and reduces the cutting temperature.

Description

technical field [0001] The invention relates to a non-equidistant texture finish machining antifriction turning blade. The invention belongs to the technical field of metal cutting tool wear reduction, and is mainly used in the finishing process of high-temperature alloys under steam-mist cooling. Background technique [0002] Nickel-based superalloy GH4169 is a nickel-based alloy material with high hardness, high strength, corrosion resistance and high temperature resistance, which can maintain good stability even in very harsh environments. Because of its excellent performance, it has been widely used in aviation field in recent years. Nickel-based superalloy GH4169 is often used to make heat-resistant parts such as discs and blades of aerospace engines and gas turbines, and occupies an important position in the aviation, aerospace and atomic energy industries. In recent years, with the rapid development of the defense industry, great progress has been made in the fields...
