Novel abrasion reduction turning tool blade for high-temperature alloys

Abstract

The invention discloses a novel abrasion reduction turning tool blade for high-temperature alloys and relates to the technical field of abrasion reduction turning tool blades. A tool body is rhombic and is in a central symmetry mode. A main cutting edge of the tool body is linear. Main rear tool face microstructures, auxiliary rear tool face microstructures, front tool face microstructures and chip breaker groove face microstructures are distributed in the area, close to the tool tip, of the main rear tool face of the tool body, the area, close to the tool tip and the main cutting edge, of theauxiliary rear tool face, the position, close to the tool tip and the main cutting edge, of the front tool face of the tool body and the area, close to the tool tip, of chip breaker grooves correspondingly in an array mode. The tool body is provided with semispherical protrusions and symmetrical streamlined protrusions, and the symmetrical streamlined protrusions and the semispherical protrusionsform the chip breaker grooves. Blade bottom heat dissipation grooves are formed in the bottom of the tool body. A fastening screw hole is formed in the middle of the tool body. By means of the novelabrasion reduction turning tool blade for the high-temperature alloys, the tool-chip friction force and the tool-chip contact area can be reduced, curling of cuttings is increased, the chip breaking capacity of the tool and the heat dissipation performance are improved, and the service life is prolonged.

Description

technical field [0001] The invention relates to a novel wear-reducing turning blade for high-temperature alloys, and belongs to the technical field of wear-reducing turning blades. Background technique [0002] With the development of science and technology, the machinery industry is constantly undergoing technological innovations, and the field of mechanical precision machining is the foundation and pillar of the machinery industry. Its development directly affects the overall level of machinery. Especially in recent years, with the continuous progress of materials science, various difficult-to-machine materials continue to appear, which poses new challenges to the field of machining industry. Under the background of difficult processing materials and high processing precision, the upgrading of cutting inserts is also imperative. The current traditional cutting blades have high friction and high cutting temperature during cutting, so the blades are easy to wear, and the cu...

AI Technical Summary

Problems solved by technology

The surface roughness of the parts processed after the blade is worn is low, the dimensional accuracy of the parts is low, and the temperature is high during cutting, and the tool life is short, especially when processing special materials such as superalloys.
