Abstract

A cemented carbide cutting tool provided by the present invention is mainly characterized in that it consists of the following raw materials in parts by weight: 65-78 parts of hard phase, 10-12 parts of binder phase, 6-8 parts of inhibiting phase, 2-4 parts hardened phase. The cemented carbide cutter provided by the invention overcomes the defects of the prior art, has a simple manufacturing process, and effectively improves the hardness, strength and toughness of the cemented carbide cutter.

Description

technical field [0001] The invention belongs to the technical field of tool processing, and in particular relates to a cemented carbide tool. Background technique [0002] Because of its high hardness and wear resistance, cemented carbide is widely used to make wear-resistant parts, cutting tools, molds, mining tools, geological drilling tools, oil extraction tools, structural parts, high temperature and high pressure cylinders Body and mechanical seal parts, etc. At present, the cutting speed of cemented carbide cutting tools is hundreds of times higher than that of carbon steel, and 4-7 times higher than that of high-speed steel. However, they generally have the problems of low bending strength, poor impact toughness, high brittleness and easy wear. To solve the above problems, most of the cemented carbide tools are heat treated. The heat treatment of an existing cemented carbide tool adopts salt bath quenching or oil quenching, and then tempering treatment process, alth...
