Cemented carbide is the most widely used type of high-speed machining (HSM) tool material. This type of material is produced by powder metallurgy, and consists of hard carbide (usually tungsten carbide WC) particles and a softer metal bond composition.

Want to be applied to high-performance, high-precision CNC machine tools, while achieving stability and better processing efficiency, generally put forward higher requirements than ordinary tools for carbide CNC tools from design to manufacturing and use.

The cemented carbide is made of tungsten carbide powder as a matrix, and is pressed and sintered with cobalt powder as a binder. Usually contains 94% tungsten carbide and 6% cobalt. Because of its high hardness, it is very wear-resistant and has a certain strength, suitable for high-speed cutting.

Cemented carbides or hard metals as they are often dubbed are a class of materials made by ‘cementing’ grains of tungsten carbide in a binder matrix of the metal cobalt by a process called liquid phase sintering.

Tungsten carbide (WC) has excellent properties of high hardness, high strength, high rigidity, good wear resistance, and thermal conductivity. It has wide application files of tools in the metalworking, drilling, and mining industries under severe conditions of high-pressure

Indexable carbide inserts are the industry workhorses. Even though these carbide inserts cost less than some other tools, they have the loosest tolerances, from 0 to 0.012 in., depending on the ratio of length to diameter.

Tungsten Carbide blades are known for being sharp and durable. They are wear-resistant, and can be used in a variety of industrial applications where extremely sharp cutting instruments are needed.

The main problem that may occur during the milling process is the possibility that chips may choke the tool. If a milling cutter is finally choked, it cannot carry out chips any more and the feeding force of the spindle will break it.

Designing for Carbide Designing for Carbide requires special considerations in the area of selecting safety factors based on stress, toughness, impact and corrosion characteristics. Components should be designed within these parameters for optimum performance.

The hardness of the metal is the ability of the metal material to resist local deformation, especially plastic deformation, indentation or scratching. It is an indicator to measure the degree of softness and hardness of the metal material.
