Basic Concepts Of Cemented Carbide Inserts

The industrial application of cemented carbide inserts in metal cutting began in the 1930s. Since then, cemented carbide has evolved into the most common tool material so far. Tools with relatively small size are often made of integral cemented carbide; Non integral cemented carbide tools use cemented carbide only in the cutting area.

Cemented carbide is also called TC, because the main component of cemented carbide is tungsten carbide, which is a material with very high hardness, and it has a series of excellent properties such as wear resistance, good strength and toughness, heat resistance and corrosion resistance. It has been widely used in cutting tools mainly used in metal cutting and processing.

Cemented carbide is a kind of alloy material, which is used to cut cast iron, non-ferrous metals, glass, stone and ordinary steel. It can also be used to cut difficult materials such as heat-resistant steel, stainless steel and tool steel. However, due to its high price, most manufacturers will give priority to high-speed steel on the premise of maintaining good cutting of blades.

However, compared with high-speed steel tools, using cemented carbide tools to process workpieces can not only obtain better machined surface quality, but also obtain higher machining speed; Cemented carbide tools can withstand higher cutting heat, which is the main reason why they can achieve higher metal removal rate. When machining difficult processed materials such as high alloy steel or stainless steel, or in the case of mass production and capacity expansion, such high-speed steel tools are easy to wear quickly, the use of cemented carbide tools can usually make the cutting performance better
