Application of Ultra-fine Grain Cemented Carbide

What is Ultra-fine Grain Tungsten Carbide?

Ultra-fine grain cemented carbide is a kind of cemented carbide with high hardness, strength, and wear resistance. The mutual adsorption-diffusion effect during processing is small. Ultra-fine grain cemented carbide is suitable for processing heat-resistant alloy steel, titanium, high-strength non-metallic brittle materials, and metal materials. It can also be applied to manufacture materials such as glass, marble, granite, FRP, and other non-ferrous metals, as well as tungsten, molybdenum, and other alloys.

High-quality cutting tool material

Due to the high toughness and strength, high hardness, and wear resistance of ultra-fine-grained cemented carbide, a high-precision edge can be obtained as a cutting tool, allowing a large rake angle to ensure a sharp edge. Therefore, it can withstand larger cutting forces and a higher surface finish. It can improve the precision of the tool and the finish of the processing material by 1-3 times, especially in the processing of heat-resistant alloys, titanium alloys, and chilled cast iron, showing good cutting performance.

Ultra-fine-grained carbide tools can machine high-strength steels, heat-resistant alloys, and stainless steels with more than twice the service life of P01 or K10 alloys.

Such as machining these ultra-fine grained carbide tools, the service life of these materials is more than ten times longer than that of carbide tools.

The development of ultra-fine grained carbide has laid the foundation for the development of carbide end mills and carbide twist drills. Carbide end mills and twist drills are made of high-strength, high-hardness, ultra-fine-grained carbide to ensure center-edge cutting performance.

Carbide End Mills

Carbide end mills are widely used in the mold industry (especially plastic mold industry), automobile industry, IT, and related industries. The plastics industry uses a large amount of pre-hardened HRC 30-34 plastic mold steel as raw materials, whose machine ability is poor in hardness. High-precision pattern cavities with good surface roughness can be efficiently machined using only carbide end mills. Solid carbide end mills with diameters of 0.1mm to 8mm are widely used to process round glass fiber to reinforce printed circuit boards and perform micromachining.

Carbide Drill

Solid carbide twist drills are rapidly developing to meet the high efficiency of the automotive industry and the processing of plastic reinforced fiberglass boards (PCBs) in the IT industry. When drilling on the PCB, the hole of the hole has no glass fiber hair, and the high-speed steel twist drill cannot meet the requirements, and a solid carbide twist drill must be used. With the rapid development of electronics, information, and other industries, the demand for cemented carbide twist drills will continue to grow.
