Abstract

The invention discloses a microstructure superhard cutter and a manufacturing method thereof. The microstructure superhard cutter comprises a cutter body and a cutter head connected with the cutter body, wherein the cutter head comprises a rake face, a flank face and a tip; a microstructure depressed downwards is arranged on the rake face; and a chip breaking structure for cutting off accumulatedchips is arranged on one side, away from the tip, of the microstructure. The manufacturing method of the microstructure superhard cutter comprises the following steps: S1, adjusting the relative position of a laser and the to-be-machined cutter; S2, turning on the laser to irradiate the rake face of the to-be-machined cutter; S3, controlling the laser to move along a predetermined path. The microstructure with high precision can be machined on the cutter with high hardness, the cutter is suitable for suitable for batch production; and the cutter with the micro structure ahs the advantages thatthe heat dissipation area in the cutting process can be increased, cutting heat is reduced, and the service life of the cutter is prolonged.

Description

technical field [0001] The invention relates to the technical field of superhard tool processing, in particular to a microstructure superhard tool and a manufacturing method thereof. Background technique [0002] Tool wear is a key issue in the process of mechanical manufacturing. The friction between the tool and the workpiece will inevitably cause tool wear, affect the processing efficiency and service life of the tool, and increase the processing cost. Tribology and bionics studies have shown that the smoother the surface of the tool, the more wear-resistant it is. A certain micro-pits structure is created on the surface of the tool, which can play a role in reducing vibration and wear resistance, and can improve the lubrication effect and make it more wear-resistant. friction performance. [0003] PCD superhard cutting tools are widely used in processing materials with high hardness. PCD cutting tools have the characteristics of high hardness, high compressive strength,...
