Three ways to manufacture carbide rod
Extrusion is the most popular method of producing carbide rods. It is a very practical way to manufacture long carbide rods like 330mm.310mm and 500mm, etc. However, its time-consuming drying process is the weakness that we have to pay attention to.
Automatic pressing is the most effective ways to press short sizes like 6*50,10*75,16*100, etc. It can save cost from cutting carbide rods and it doesn’t need time to dry. So the lead time is faster than extrusion. On the other hand, long rods cannot be manufactured by this method.
Cold Isostatic Press
Cold isostatic press(CIP) is the latest technology of making carbide rods. Because it can make long bars like 400mm but it doesn’t require wax like extrusion, so it doesn’t need time to dry, either. This is the best option when making big diameters like 30mm and 40mm.
Applications of tungsten carbide rods
Carbide rods are mainly used for drills, end mills, and reamer. It can also be used for cutting, stamping and measuring tools. It is used in the paper, packaging, printing, and non-ferrous metal processing industries. In addition, it is also widely used in the processing of high-speed steel tools, carbide milling cutters, carbide tools, carbide drills, high-speed steel, carbide tools, etc. Carbide rods can be used not only for cutting and drilling tools but also for input needles, various roll wore parts and structural materials. In addition, it can be used in many fields, such as machinery, chemical, petroleum, metallurgy, electronics and defense industries

What is ultra-fine cemented carbide?
Ultra-fine grain cemented carbide is a high hardness, high strength and high wear resistance both carbide, and the processing of mutual adsorption – diffusion effect is small, suitable for processing heat-resistant alloy steel, titanium, high High strength non-metallic brittle materials and metal materials such as glass, marble, granite, Plastic reinforced glass fiberboard and other cutting and non-ferrous metals tungsten, molybdenum and other alloy processing.
As the ultra-fine grain cemented carbide with high toughness and strength, high hardness and wear resistance, so as a cutting tool to obtain high-precision edge, allowing the use of large rake angle to ensure sharp blade edge. So that it can withstand a large cutting force, and can get a high finish of the machined surface.
It can improve the precision of the tool and the finish of the machined material by 1 ~ 3, especially in the processing of heat-resistant alloy, titanium alloy, chilled cast iron, and other aspects show good cutting performance. Ultra-fine grain carbide cutting tool processing high-strength steel, heat-resistant alloys, and stainless steel, life than P01 or K10 alloy more than doubled
Ultra-fine grain carbide cutting tool processing these materials better than ordinary carbide cutting tool and the life is more than 10 times higher. The development of ultrafine grain cemented carbide has been developed to build the foundation of cemented carbide end mills and carbide twist drills.
Carbide end mills and twist drills are generally made of high strength, high hardness, ultrafine grain cemented carbide to ensure the cutting performance of the center edge. Carbide end mills are widely used in the mold industry (especially plastic mold industry), the automotive industry, IT and related industries. The plastic industry has a large number of pre-hardened HRC30-34 plastic mold steel as raw materials, in which the hardness of its machinability is poor, only the use of carbide end mills high-efficiency processing of good surface roughness of high precision mode Cavity.
At present, carbide end mills have been used in automobile production lines, IT and related industries extensive use of Ф0.1 ~ 8mm overall carbide end mill processing glass fiber reinforced printed circuit board around and micro-processing.
Solid Carbide Twist Drill is rapidly evolving to meet the high efficiency of the automotive industry and the processing of plastic reinforced glass fiber boards (PCBs) in the IT industry. Drilling on the PCB, the hole of the hole without glass fiber hair, high-speed steel twist drill cannot meet the requirements, and must use the overall carbide twist drill. With the rapid development of electronics, information and other industries, the demand for carbide twist drill will be growing.
