Abstract

The invention relates to the technical field of metal cutting, and discloses a double-face groove profile cutting blade. A blade body is of a geometric structure, wherein the geometric structure is provided with a polygon and is symmetric up and down. A positioning hole is formed in the geometric center. The blade body is composed of an upper end face, a lower end face, a plurality of side surfaces and an arc side face located between every two adjacent side surfaces, and the upper end face and the lower end face are provided with supporting surfaces between the edges of scrap cutting tables and the positioning hole. The top corner of the blade is provided with no fewer than one cutting unit part, and each cutting unit part is composed of a cutting edge, the corresponding scrap cutting table and a scrap cutting guiding protruding part, wherein the scrap cutting table is composed of a front blade face and a plurality of cutting guiding faces, the scrap cutting guiding protruding part isarranged at the top corner of the cutting unit part, and the cutting edge is composed of an arc cutting edge body, a main cutting edge body, a transition cutting edge body and an auxiliary cutting edge body. Through the blade, the sharpness and stability of the cutting edges are improved, scrap cutting and discharging are smooth, blade abrasion is reduced, and the phenomenon of built-up edges iseffectively restrained.

Description

technical field [0001] The invention relates to the technical field of metal cutting, and more specifically, to a double-sided groove cutting insert. Background technique [0002] Materials such as stainless steel and nickel-based alloys have high alloy element content and strong plastic deformation ability. Usually, the cutting force is large during turning, which generates a lot of heat, which makes the temperature of the tool rise sharply, resulting in the deformation of the tool material. The strength decreases, which increases the wear of the tool due to high temperature oxidation; [0003] At the same time, stainless steel often causes work hardening due to plastic deformation during the processing process, which causes the chips in the cutting process to become tough. During the processing process, if the flow direction and discharge of the chips are not properly guided, this will lead to uncontrolled chip flow. It will cause scratches on the processed surface, and e...
