Abstract

The invention relates to a cubic boron nitride / titanium carbide compound sintered cutter material. The cutter material is mainly prepared by sintering the following raw materials in part by weight: 40 to 70 parts of cubic boron nitride microlite with the granularity between 1 and 20 mu m, 30 to 50 parts of titanium carbide microlite with the granularity between 1 and 4 mu m, 0.05 to 0.5 part of silicon powder with the granularity between 1 and 3 mu m, 0.05 to 0.5 part of carbon powder with the granularity of 300 meshes, 0.1 to 2 parts of tungsten carbide powder with the granularity between 1and 3 mu m, and 1 to 10 parts of aluminum powder with the granularity between 2 and 10 mu m. The hardness of the cutter material is HV 5,500 to 6,500, and the bending strength is 1,000 to 1,500 Mpa. Cutters made of the cutter material are applied to machining gears after quenching, and can be used under the condition that the on-line velocity is 300m, the machining efficiency of the cutters is more than 1.5 times that of the conventional cutters, and the service life is more than 2 times that of the conventional cutters.

Description

technical field [0001] The invention belongs to the technical field of high-hard technical materials, and in particular relates to a cubic boron nitride / titanium carbide composite sintered tool material and a preparation method thereof. Background technique [0002] At present, cemented carbide is generally used as the tool material for knives. This material has poor hardness and wear resistance, and is prone to wear and tear, resulting in a short service life of the tool. Especially in the gear processing industry, the requirements for the wear resistance and hardness of the tool material are higher. Therefore, it is imperative to develop a cutting tool material with high hardness, good wear resistance, excellent mechanical properties and reasonable cost performance. Contents of the invention [0003] The purpose of the present invention is to solve the above-mentioned technical problems existing in the prior art, and provide a cubic boron nitride / titanium carbide compos...
