Description

technical field [0001] The invention belongs to the technical field of cutting tools, and in particular relates to an alloy material for cutting tools and a preparation method thereof. Background technique [0002] In mechanical processing, the tool is constantly in contact with the chip and the workpiece and undergoes strong friction during cutting, which can easily cause sharp wear of the tool, thereby reducing the tool life. In the field of machining, alloy steel is the most widely used cutting tool material. The hardness, toughness and wear resistance of traditional alloy steel tools are not good. During mechanical cutting, they are easy to break and wear and need to be replaced frequently, which increases the cost of cutting. In addition, for some materials with high hardness or products with special shapes and sizes In some cases, traditional alloy steel knives are not up to the task. Therefore, it is necessary to provide a material for cutting tools with good hardne...
