What is cemented carbide material?
Cemented carbide material is an alloy material made of a hard compound of refractory metals and a bonding metal through a powder metallurgy process.
What are the parts of cemented carbide blades?
Carbide-based matrix.Among the carbide blade materials whose main component is tungsten carbide, the type with very small particles is usually called micro-carbide, and can be used for turning tools of small automatic machine tools or carbide materials for low-speed cutting at 40~50m/min on small-diameter end mills.
Coating. The surface coating of cemented carbide blades refers to a layer of titanium carbide, titanium nitride or aluminum oxide about 1~2μm thick on the surface of the blade. Its toughness is similar to that of cemented carbide materials, and its hardness at high temperature is similar to that of alloy ceramics or ceramics.
What is alloy ceramic?
The material with performance between carbide blades and ceramics is alloy ceramic, which is a composite term for ceramic and metal. Its main component is titanium carbide, which is then mixed with a small amount of titanium nitride or tungsten carbide and sintered with nickel or molybdenum as a binder. Alloy ceramics have good high-temperature wear resistance and low affinity with iron, so they are very suitable for high-speed finishing.
What are CBN and PCD blades?
Nowadays, the use of blades made of fine powder of cubic boron nitride or artificial diamond is increasing. The former is called CBN tool, and the latter is called sintered diamond tool.
In short, as the market demand for cemented carbide blades increases, cemented carbide blade materials, coatings and technologies are in line with market development, and are constantly innovating and developing. New technical formulas are also updated iteratively to meet different market needs.
