Cast metal cutting high wear-resistant industrial tool

Abstract

The invention relates to a casted high-wear-resistance industrial cutter for metal cutting. The casted high-wear-resistance industrial cutter consists of the following components in percentage by weight: 40%-70% of niobium carbide, 5%-15% of chromium carbide, 5%-15% of titanium nitride, 0.1%-5% of boron nitride, 1%-10% of carbon powder, 5%-20% of a forming agent, 0.2%-0.5% of alumina, 0.2%-0.4% of calcined kaolin, 0.05%-0.1% of tungstate, 0.1%-0.6% of heavy rare earth and 0.1%-0.3% of zirconia. The casted high-wear-resistance industrial cutter is high in hardness and good in wear resistance and has obvious superiorities in thermal stability, thermal conductivity, corrosion resistance, oxidation resistance, high temperature hardness and high temperature strength; the cutter can be used for continuously and rapidly cutting at a high temperature, the friction force is low during the cutting, the cutting is relatively strong, notches are relatively neat, and the burr is avoided; the cutter is applied to cutting machining and production, the cutting speed can be greatly increased, and then the production efficiency is improved; the cutter can be used for machining various difficultly-cut materials and is high in machining accuracy and product precision; furthermore, production materials are safe and environmentally friendly, so that the cutter is relatively safe and secure when used for cutting foods and medicines, thereby being beneficial to environmental protection.

Description

technical field [0001] The invention relates to the technical field of cutting tools, in particular to a cast metal cutting high wear-resistant industrial cutting tool and a preparation process thereof. Background technique [0002] With the continuous improvement of human living standards, the demand for resources is also increasing, and the operating costs of resources and new problems brought about by opening up in increasingly difficult rock formations have brought about the strength of the tool's resistance to fracture and fatigue fracture. Therefore, higher requirements are put forward for wear-resistant materials with high hardness and high strength, new parts, new tools, and tools suitable for extreme conditions. , Traditional cemented carbide is widely used in various cutting tools due to a series of excellent properties such as high strength and hardness, good wear resistance, good red hardness, small thermal expansion coefficient, high elastic modulus and good che...

Problems solved by technology

Compared with other tool materials, the most obvious disadvantages of ceramic tools are insufficient fracture toughness, poor bending strength and thermal shock resistance, and cracks are prone to occur when the cutting temperature changes significantly
